Autores: Maffezzoli, Niccolò; Vallelonga, Paul; Edwards, Ross; Saiz-lopez, Alfonso; Turetta, Clara; Kjær, Helle Astrid; Barbante, Carlo; Vinther, Bo; Spolaor, Andrea.
Although it has been demonstrated that the speed and magnitude of recent Arctic sea ice decline is unprecedented for the past 1,450 years, few records are available to provide a paleoclimate context for Arctic sea ice extent. Here we present a 120 kyr record of bromine enrichment from the RECAP ice core, coastal East Greenland, and reconstruct past sea ice conditions in the North Atlantic as far north as the entrance of the Arctic Ocean (50–85° N). Bromine enrichment has been previously employed to reconstruct first-year sea ice (FYSI) in the Canadian Arctic over the last glacial cycle. We find that during the last deglaciation, the transition from multi-year sea ice (MYSI) to FYSI started at ∼ 17.6 kyr, synchronous with sea ice reductions observed in the...

Provedor de dados: 87
Autores: SILVA,J.R.O.; MARQUES,J.N.R.; GODOY,C.V.C.; BATISTA,L.B.; SILVA,A.A.; RONCHI,C.P.
ABSTRACT: The hormesis effect of 2,4-D, applied at two stages of soybean development, on the physiological components of crop yield, was investigated. Soybean seeds of the cultivar ‘AG 3680 IPRO’ were sown in pots containing 7 L of a substrate and kept in a greenhouse. A randomized complete block design with four replicates was used. Eighteen treatments were tested, arranged in a split-plot scheme. The plots consisted of two stages of herbicide application (V4 and V6), and the split-plots were arranged by nine 2,4-D doses (0, 5, 10, 15, 20, 25, 30, 40, and 50 g ha-1). At the time of harvest, 100 days after sowing, significant interactions between crop development stages and 2,4-D doses were observed for the number of nodes in the main stem (NNMS) and the...

3-D crustal density model of the Sea of Marmara
Provedor de dados: 5
Autores: Gholamrezaie, Ershad; Scheck-wenderoth, Magdalena; Bott, Judith; Heidbach, Oliver; Strecker, Manfred R.
The Sea of Marmara, in northwestern Turkey, is a transition zone where the dextral North Anatolian Fault zone (NAFZ) propagates westward from the Anatolian Plate to the Aegean Sea Plate. The area is of interest in the context of seismic hazard of Istanbul, a metropolitan area with about 15 million inhabitants. Geophysical observations indicate that the crust is heterogeneous beneath the Marmara basin, but a detailed characterization of the crustal heterogeneities is still missing. To assess if and how crustal heterogeneities are related to the NAFZ segmentation below the Sea of Marmara, we develop new crustal-scale 3-D density models which integrate geological and seismological data and that are additionally constrained by 3-D gravity modeling. For the...

3-D environmental extreme value models for the tension in a mooring line of a semi-submersible
Provedor de dados: 5
Autores: Raillard, Nicolas; Prevosto, Marc; Pineau, H.
Design optimization is crucial as offshore structures are exposed to deeper and harsher marine conditions. The structure behaviour is dependent on several joint environmental parameters (wind, wave, currents, etc.). Environmental contours are useful representations to provide multivariate design conditions. However, these contours may lead to different design points depending on the method used to compute them, and thus may be misleading to structural engineer. In this work, we propose to use a response meta-model for the inter-comparison of some state-of-the-art methods available for modelling multivariate extremes, in order to provide a straightforward methodology, focusing on the derivation of three-dimensional contours. The considered case study...

6-Bromoindirubin-3’-oxime promotes osteogenic differentiation of canine BMSCs through inhibition of GSK3β activity and activation of the Wnt/β-catenin signaling pathway
Provedor de dados: 42
Autores: ZHAO,XIAO-E; YANG,ZHENSHAN; GAO,ZHEN; GE,JUNBANG; WEI,QIANG; MA,BAOHUA.
﻿﻿This﻿﻿ study aimed to investigate how 6-bromoindirubin-3’-oxime (BIO) increases the osteogenic differentiation of canine bone mesenchymal stem cells (BMSCs) and the role of the Wnt/β-catenin signaling pathway in this process. We mimicked the effect of Wnt by adding BIO to the culture medium of BMSCs and examined whether canonical Wnt signaling positively affects the differentiation of these cells into osteoblasts. Canine BMSCs were cultured with 0.5 and 1.0 μM BIO under osteogenic conditions and then differentiation markers were investigated. It was found that BIO significantly increased the activity of alkaline phosphatase (ALP), the number of ALP-positive cells, the mineralization level and calcium deposits. Moreover, cells cultured with 0.5 and 1.0 μM...

80’s population-specific compositions of two related anadromous shad species during the oceanic phase determined by microchemistry of archived otoliths
Provedor de dados: 5
Autores: Nachón, David José; Bareille, Gilles; Drouineau, Hilaire; Tabouret, Helene; Taverny, Catherine; Boisneau, Catherine; Berail, Sylvain; Pécheyran, Christophe; Claverie, Fanny; Daverat, Françoise.
The specific stock composition and dispersion of anadromous fish species aggregations in the marine environment are poorly known, while they can play a major role in the metapopulation dynamics. Otolith microchemistry has proven to be a powerful tool to address natal origins of anadromous fish. We used archived otolith microchemistry to investigate the population-specific composition of European shads (Alosa alosa and Alosa fallax) subadults in the ocean during the 80’s. The allocation of natal origin was addressed relying on contemporary water and juveniles signatures within a Bayesian model. A great discrimination of natal origin was obtained at the Biscay Gulf scale. However, the discrimination of 80’s natal origin for the southern rivers with similar...

A 5.3‐million‐year history of monsoonal precipitation in northwestern Australia
Provedor de dados: 5
Autores: Stuut, Jan‐berend W.; De Deckker, Patrick; Saavedra‐pellitero, Mariem; Bassinot, Franck; Drury, Anna‐joy; Walczak, Maureen H.; Nagashima, Kana; Murayama, Masafumi.
New proxy records from deep‐sea sediment cores from the northwestern continental margin of Western Australian reveal a 5.3 million‐year (Ma) history of aridity and tropical‐monsoon activity in northwestern Australia. Following the warm and dry early Pliocene (~5.3 Ma), the northwestern Australian continent experienced a gradual increase in humidity peaking at about 3.8 Ma with higher than present‐day rainfall. Between 3.8 and about 2.8 Ma, climate became progressively more arid with more rainfall variability. Coinciding with the onset of the northern hemisphere glaciations and the intensification of the northern hemisphere monsoon, aridity continued to increase overall from 2.8 Ma until today, with greater variance in precipitation and an increased...

Autores: LOPES, M. A.
A Amazônia é, de longe, o melhor estudo de caso para inserção do Brasil na economia natural do conhecimento. Primeiro, porque precisamos estar mais preparados a argumentar de forma mais inteligente e assertiva com aqueles que insistem que o Brasil deve se responsabilizar sozinho, e de graça, por uma enorme fatia da proteção ambiental do planeta. Segundo, porque já vemos emergir no mundo uma nova economia de base biológica, em segmentos vitais como a agricultura, a saúde, e as indústrias química, de materiais e de energia. E a biodiversidade, a maior riqueza da Amazônia , é matéria-prima essencial para o futuro dessa bioeconomia.

The Biogeochemical-Argo program (BGC-Argo) is a new profiling-float-based, ocean wide, and distributed ocean monitoring program which is tightly linked to, and has benefited significantly from, the Argo program. The community has recommended for BGC-Argo to measure six additional properties in addition to pressure, temperature and salinity measured by Argo, to include oxygen, pH, nitrate, downwelling light, chlorophyll fluorescence and the optical backscattering coefficient. The purpose of this addition is to enable the monitoring of ocean biogeochemistry and health, and in particular, monitor major processes such as ocean deoxygenation, acidification and warming and their effect on phytoplankton, the main source of energy of marine ecosystems. Here we...

A biomechanical study on proximal junctional kyphosis following long-segment posterior spinal fusion
Provedor de dados: 56
Autores: Zhu,Wen-Yi; Zang,Lei; Li,Jian; Guan,Li; Hai,Yong.
Posterior long-segment spinal fusion may lead to proximal junctional kyphosis (PJK). The present study sought to identify the appropriate fusion levels required in order to prevent PJK using finite element analysis. A finite element model was constructed based on the whole-spine computed tomography findings of a healthy adult. Nine commonly used posterior spinal fusion methods were selected. Stress on the annulus fibrosis fibers, the posterior ligamentous complex, and the vertebrae after various spinal fusions in the upright position were compared. This study was divided into two groups: non-fusion and fusion. In the former, the stress between the T10 and the upper thoracic vertebrae was higher. Comparing thoracic and lumbar segments in the fusion group,...

A bomba-relógio do consumismo.
Provedor de dados: 14
Autores: LOPES, M. A.
A economia global tem se comportado como se os recursos materiais do planeta fossem ilimitados, consumindo biomassa, combustíveis fósseis e minerais em volumes que chegam a 90 trilhões de toneladas anualmente, ou três vezes o volume extraído em 1970. Hoje nos damos conta de que não é mais possível sustentar um modelo econômico baseado no consumo sem limites. A escalada no consumo e sua relação com o desperdício e outro assunto que precisa ganhar a atenção das lideranças e dos formuladores de políticas públicas. Muitos acreditam que o desenvolvimento tecnológico nos permitirá alcançar novos patamares de eficiência no uso de recursos, levando a reduções na sua demanda e uso.

Conhecer a atmosfera do planeta Terra é uma das aspirações que vêm sendo perseguidas pela humanidade desde os tempos mais remotos. A partir do momento em que o homem tomou consciência da interdependência das condições climáticas e daquelas resultantes de sua deliberada intervenção no meio natural, como necessidade para o desenvolvimento social, ele passou a produzir e registrar o conhecimento sobre os componentes da natureza (MENDONÇA; DANNI-OLIVEIRA, 2007). A agricultura é uma das atividades econômicas mais dependentes das condições climáticas.

We report a botulism outbreak in Charolais cattle fed with wheat flour contaminated by Clostridium botulinum type C and the management of the outbreak at each step from the clinical suspicion to the cleaning and disinfection operations. Diagnosis was based on typical suggestive clinical signs and detection of C. botulinum type C using real-time PCR in samples collected from three young affected bulls. All young exposed bulls and cows (18 animals) eventually died, but three young bulls and one cow were recovering when it was decided to euthanize them. C. botulinum type C was detected in the liver of these four animals. Analysis of the ration components demonstrated that wheat flour, wheat, and the mill used to make flour were positive for C. botulinum type...

A COMBINATION OF DISCRETE EVENT SIMULATION AND MULTI-CRITERIA ANALYSIS TO CONFIGURE SUGARCANE DROP AND HOOK DELIVERY SYSTEMS
Provedor de dados: 70
Autores: Faria,Danilo A. F. de; Frazão,Márcia L. da S.; Vieira,José G. V.; Silva,João E. A. R. da; Lemos,Paula H.
ABSTRACT This article explores decision analysis regarding Drop and Hook (D&amp;H) transportation operations at sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different configurations for sugarcane delivery systems using internal, external, or no D&amp;H systems. A D&amp;H strategy maximises truck utilisation, as semi-trailers can be handled independently of the traction unit of the trucks, which makes the transport system more agile. For internal D&amp;H systems the semi-trailer detaching/attaching point is located inside the mill site while for external D&amp;H systems it is located outside, before the trucks’ weighbridge. Each configuration requires...

Host-microbe interactions play crucial roles in marine ecosystems, but we still have very little understanding of the mechanisms that govern these relationships, the evolutionary processes that shape them, and their ecological consequences. The holobiont concept is a renewed paradigm in biology that can help describe and understand these complex systems. It posits that a host and its associated microbiota, living together in a long-lasting relationship, form the holobiont, and have to be studied together, as a coherent biological and functional unit, in order to understand the biology, ecology and evolution of the organisms. Here we discuss critical concepts and opportunities in marine holobiont research and identify key challenges in the field. We...

A comparative assessment of the uncertainties of global surface ocean CO2 estimates using a machine-learning ensemble (CSIR-ML6 version 2019a) - have we hit the wall?
Provedor de dados: 5
Autores: Gregor, Luke; Lebehot, Alice D.; Kok, Schalk; Monteiro, Pedro M. Scheel.
Over the last decade, advanced statistical inference and machine learning have been used to fill the gaps in sparse surface ocean CO2 measurements (Rodenbeck et al., 2015). The estimates from these methods have been used to constrain seasonal, interannual and decadal variability in sea-air CO2 fluxes and the drivers of these changes (Landschutzer et al., 2015, 2016; Gregor et al., 2018). However, it is also becoming clear that these methods are converging towards a common bias and root mean square error (RMSE) boundary: "the wall", which suggests that pCO(2) estimates are now limited by both data gaps and scale-sensitive observations. Here, we analyse this problem by introducing a new gap-filling method, an ensemble average of six machine-learning models...

A Computational Framework for Daily Power Flow Analysis Considering Photovoltaic Distributed Generation
Provedor de dados: 52
Autores: Gurski,Erico; Moraes,Fillipe Alexandre; Fritzen,Paulo Cícero; Benedito,Raphael Augusto de Souza.
Abstract In Brazil, the demand for the acquisition and installation of photovoltaic systems has grown exponentially and, with that, the importance of studies considering their effects on the distribution grids power flow also grows. Due to the intermittent nature of photovoltaic generation, it is important to approach the analysis in a discrete way, taking into account the changes in the power injections during the studied period. Thus, this article presents the daily analysis of the effects of photovoltaic generation on the distribution system through the computational implementation of a discretized power flow routine. The implemented routine can also analyze the effects of other distributed generations on distribution grids, whether those grids are...

A decision-making framework to reduce the risk of collisions between ships and whales
Provedor de dados: 5
Autores: Sèbe, Maxime; Kontovas, Christos, A.; Pendleton, Linwood.
Ship strikes are one of the main human-induced threats to whale survival. A variety of measures have been used or proposed to reduce collisions and subsequent mortality of whales. These include operational measures, such as mandatory speed reduction, or technical ones, such as detection tools. There is, however, a lack of a systematic approach to assessing the various measures that can mitigate the risk of ship collisions with whales. In this paper, a holistic approach is proposed to evaluate mitigation measures based on a risk assessment framework that has been adopted by the International Maritime Organization (IMO), namely the Formal Safety Assessment (FSA). Formal Safety Assessment (FSA) is “a rational and systematic process for assessing the risk...

Resumo O arroz é um alimento básico na dieta do brasileiro; contudo, o lento crescimento de seu consumo tem impactos diretos na expansão do setor. Para compreender os fatores que afetam esse consumo e suas inter-relações com outros alimentos foram estimadas, neste estudo, as elasticidades da demanda por dez alimentos nos domicílios brasileiros, utilizando dados da Pesquisa de Orçamentos Familiares 2008-2009. Para tanto, foi aplicado o modelo Quadratic Almost Ideal Demand System (Quaids) ajustado para o problema do consumo censurado e da endogeneidade das despesas. Os resultados gerais indicam que o arroz apresenta elasticidade-dispêndio menor que a unidade. A elasticidade-renda da demanda reforça esse comportamento de bem necessário, sendo mais elevada em...

A Design and Analysis Methodology for Component-Based Real-Time Architectures of Autonomous Systems
Provedor de dados: 5
Autores: Gobillot, Nicolas; Lesire, Charles; Doose, David.
The integration of autonomous robots in real applications is a challenge. It needs that the behaviour of these robots is proved to be safe. In this paper, we focus on the real-time software embedded on the robot, and that supports the execution of safe and autonomous behaviours. We propose a methodology that goes from the design of component-based software architectures using a Domain Specific Language, to the analysis of the real-time constraints that arise when considering the safety of software applications. This methodology is supported by a code generation toolchain that ensures that the code eventually executed on the robot is consistent with the analysis performed. This methodology is applied on a ground robot exploring an area. Categories (2), (3)

A desvalorização cambial e a exportação de produtos florestais madeireiros
Provedor de dados: 123
Autores: Hersen,Amarildo; Hoeflich,Vitor Afonso; Lima,Jandir Ferrera de.
Resumo O objetivo deste artigo é analisar o comportamento das exportações de produtos madeireiros do setor florestal após a desvalorização cambial, a partir de 2012. O método de avaliação de impacto foi o de diferença em diferenças (DD). Os resultados apontam que, apesar de as exportações representarem, em média, volume menor que a comercialização doméstica, elas tiveram variação absoluta mais expressiva com a desvalorização da moeda brasileira, a partir de 2012. A expressiva queda do real frente ao dólar possibilitou uma trajetória do volume de produtos madeireiros exportados mais positiva que na hipótese de sua inexistência. Contudo, políticas públicas de inclusão do pequeno produtor e empresários do setor madeireiro poderiam ter possibilitado resultados...

A diagramatic scale to quantify severity of antracnose in Rubus glaucus Benth
Provedor de dados: 65
Autores: Patiño,Paula Andrea González; Álvarez,Gloria Edith Guerrero; Valencia,Liliana Isaza.
ABSTRACT:  Rubus glaucus Benth, commonly referred to as mora de Castilla, is affected by Colletotrichum acutatum, as it induces anthracnose in many of the plant organs. Generally, it affects the fruits during the post-harvest phase and damages them, causing economic losses due to the poor crop quality. At present, no standardized methods are available for this pathosystem that can be used to characterize quantitatively the epidemic and to permit the prediction and comparison of the disease management techniques. In this research, we proposed a logarithmic diagrammatic scale of the severity of anthracnose induced by C. acutatum in the fruits of the thornless variety of R. glaucus Benth. This scale is constructed on the adjustment of the Weber-Fechner law...

Autores: GARCIA,MAURÍCIO S.; PRETTO,FLÁVIO A.; DIAS-DA-SILVA,SÉRGIO; MÜLLER,RODRIGO T.
Abstract: Discoveries in Carnian-aged rocks are establishing a rich and diverse dinosaurian fauna at the so-called ‘dawn of the age of dinosaurs’ in the Late Triassic of Western Gondwana. Accordingly, Brazilian strata from the Candelária Sequence have contributed extensively to this trend. Here, we present a new dinosaurian specimen (CAPPA/UFSM 0200) from this geological unit. The material was collected at a fossiliferous site that had no previous record of dinosaurs. Our specimen comprises a single ilium, which we describe in detail. Its anatomy is consistent with Carnian sauropodomorph dinosaurs, but differs from coeval specimens by several features, although we do not discard the possibility of these features being the result of intraspecific variation....

A First Look at Dissolved Ge Isotopes in Marine Sediments
Provedor de dados: 5
Autores: Baronas, J. Jotautas; Hammond, Douglas E.; Rouxel, Olivier; Monteverde, Danielle R.
The removal of chemical species from seawater during the precipitation of authigenic minerals is difficult to constrain but may play a major role in the global biogeochemical cycles of some elements, including silicon (Si) and germanium (Ge). Here, we present Ge/Si, δ74Ge, and supporting chemical data of pore waters and core incubations at three continental margin sites in California and the Gulf of Mexico. We used these data to partition Ge release and uptake by the various allogenic (delivered via sedimentation) and authigenic (formed in situ) phases in these sediments. About half of the pore water Ge (δ74Gepw = 1.3–2.4‰) is supplied by biogenic silica dissolution (δ74Ge ~ 3‰), with the other half contributed by lithogenic particulates (δ74Ge ~ 0.6‰)....

Video and image data are regularly used in the field of benthic ecology to document biodiversity. However, their use is subject to a number of challenges, principally the identification of taxa within the images without associated physical specimens. The challenge of applying traditional taxonomic keys to the identification of fauna from images has led to the development of personal, group, or institution level reference image catalogues of operational taxonomic units (OTUs) or morphospecies. Lack of standardisation among these reference catalogues has led to problems with observer bias and the inability to combine datasets across studies. In addition, lack of a common reference standard is stifling efforts in the application of artificial intelligence to...

Abstract MicroRNAs (miRNAs) play an essential role in gene expression and affect the development of tumours, including breast cancer (BC). Polymorphisms in miRNA genes can affect the interaction of miRNAs with their target messenger RNA by interfering, creating or disrupting target sites. The single nucleotide polymorphism (SNP) rs2910164, located in the seed region of miR146a, was shown to be associated with BC among different populations. In the present study, we investigated whether rs2910164 is associated with BC in 326 patients and 411 controls from a Brazilian population of predominantly European ancestry. The presence of the allele rs2910164*C was associated with an increased risk of BC (OR=1.4, 95% CI=1.03-1.85, p = 0.03). We also analysed publicly...

ABSTRACT Body-size is significantly correlated with the number of vertebrae (pleomerism) in multiple vertebrate lineages, indicating that somitogenesis process is an important factor dictating evolutionary change associated to phyletic allometry and, consequently, species fitness and diversification. However, the role of the evolution of extreme body sizes (dwarfism and gigantism) remains elusive in snakes, mainly with respect to postnatal ontogeny in dietary preferences associated with evolution of gigantism in many lineages. We described herein a new species in the highly diversified and species-rich genus Atractus on the basis of four specimens from the southeastern slopes of the Ecuadorian Andes. The new species is morphologically similar and...

Plankton are the base of marine food webs, essential to sustaining fisheries and other marine life. Continuous Plankton Recorders (CPRs) have sampled plankton for decades in both hemispheres and several regional seas. CPR research has been integral to advancing understanding of plankton dynamics and informing policy and management decisions. We describe how the CPR can contribute to global plankton diversity monitoring, being cost-effective over large scales and providing taxonomically resolved data. At OceanObs09 an integrated network of regional CPR surveys was envisaged and in 2011 the existing surveys formed the Global Alliance of CPR Surveys (GACS). GAGS first focused on strengthening the dataset by identifying and documenting CPR best practices,...

A result of this interspecific encounter is the occurrence of hybrids, which are frequently found along the coasts of Amapá state in Brazil, French Guiana and Guyana. Here we present new genetic evidence indicating the occurrence of a hybrid swarm along the Guianas Shield coastline, which is an interspecific hybrid zone that also separates T. manatus populations located east (Brazil) and west (Caribbean, Gulf of Mexico, Florida and Antilles). In addition, we suggest that this hybrid population occupies a peculiar mangrove-rich environment under strong influence of the Amazon River plume, which requires an...

Autores: BOGNOLA, I. A.; LEMOS, A. V.
O conceito de produtividade florestal ou agrícola é muito amplo. Não é apenas o conceito da quantidade de um determinado produto produzido por unidade de tempo ou espaço físico (hectare, por exemplo). Conceitualmente, podemos adotar três definições: produtividade potencial, produtividade atingível e produtividade real.

Autores: Wang, Chen; Mouche, Alexis; Tandeo, Pierre; Stopa, Justin; Longépé, Nicolas; Erhard, Guillaume; Foster, Ralph C.; Vandemark, Douglas; Chapron, Bertrand.
The Sentinel‐1 mission is part of the European Copernicus program aiming at providing observations for Land, Marine and Atmosphere Monitoring, Emergency Management, Security and Climate Change. It is a constellation of two (Sentinel‐1 A and B) Synthetic Aperture Radar (SAR) satellites. The SAR wave mode (WV) routinely collects high‐resolution SAR images of the ocean surface during day and night and through clouds. In this study, a subset of more than 37,000 SAR images is labelled corresponding to ten geophysical phenomena, including both oceanic and meteorologic features. These images cover the entire open ocean and are manually selected from Sentinel‐1A WV acquisitions in 2016. For each image, only one prevalent geophysical phenomenon with its prescribed...

A Late Quaternary record of highstand shedding from an isolated carbonate platform (Juan de Nova, southern Indian Ocean)
Provedor de dados: 5
Autores: Counts, John; Jorry, Stephan; Vazquez Riveiros, Natalia; Jouet, Gwenael; Giraudeau, Jacques; Cheron, Sandrine; Boissier, Audrey; Miramontes, Elda.
A 27 m core collected on the seafloor near Juan de Nova island at 1909 m depth in the SW Indian Ocean preserves a high‐resolution record of carbonate sediment export to the deep sea over the past 1 Myr. Core chronology was established using calcareous nannofossil biostratigraphy and benthic foraminiferal δ18O. Throughout the core, preserved highstand intervals (MIS 1, 5, 7, 9, 11, 13, 15, 23 and 25) are marked by an increase in the aragonite content within the sediment. Aragonite is likely sourced from the nearby Juan de Nova carbonate platform ~10 km to the south, and is interpreted to result from flooding of the platform top. Platform inundation allows carbonate muds to be winnowed from their original shallow‐water environment of deposition, suspended in...

A literature review as an aid to identify strategies for mitigating ostreid herpesvirus 1 in Crassostrea gigas hatchery and nursery systems
Provedor de dados: 5
Autores: Rodgers, Chris; Arzul, Isabelle; Carrasco, Noèlia; Furones Nozal, Dolores.
An understanding of husbandry strategies and any associated risk factors is important for designing management control measures that can reduce mortality in Pacific oysters, Crassostrea gigas, caused by ostreid  herpesvirus 1 (OsHV-1). The type of culture facility can be considered in relation to the potential pathways that could lead to the entry of a pathogen and its survival. In addition, the animal host (e.g. age, physiological state,  selective breeding programmes), husbandry procedures (e.g. stocking density), the pathogen itself (e.g. pathogenicity, virulence) and environmental effects (e.g. temperature) represent other relevant interconnected factors. However, all these factors provide valuable background information for outlining the mitigation...

A literature review of the pollination strategies and breeding systems in Oncidiinae orchids
Provedor de dados: 39
Autores: Castro,Jonas B.; Singer,Rodrigo B.
ABSTRACT Oncidiinae is an exclusively Neotropical orchid subtribe with about 1600 described species and an impressive array of vegetative and floral morphological adaptations. We present the results of a literature survey on the pollination strategies and breeding systems of this orchid subtribe. The flowers are pollinated by a wide range of insects (mostly bees) and, sometimes, hummingbirds. Several genera reward their pollinators with floral resources such as oils, nectar or perfumes. Whereas pollination by oil-gathering bees likely evolved several times within Oncidiinae, exclusive pollination by perfume-gathering male Euglossine bees is likely restricted to a set of closely-related genera. Pollination by food or sexual deception is also present within...

A long-term field experiment demonstrates the influence of tillage on the bacterial potential to produce soil structure-stabilizing agents such as exopolysaccharides and lipopolysaccharides
Provedor de dados: 21
Autores: Cania, Barbara; Vestergaard, Gisle; Krauss, Maike; Fliessbach, Andreas; Schloter, Michael; Schulz, Stefanie.
Background: Stable soil aggregates are essential for optimal crop growth and preventing soil erosion. However, tillage  is often used in agriculture to loosen the soil, which disrupts the integrity of these aggregates. Soil aggregation can be  enhanced by bacteria through their ability to produce exopolysaccharides and lipopolysaccharides. These compounds  stabilize soil aggregates by “gluing” soil particles together. However, it has yet to be shown how tillage influences the  bacterial potential to produce aggregate-stabilizing agents. Therefore, we sampled conventional and reduced tillage treatments at 0–10 cm, 10–20 cm and 20–50 cm from a long-term field trial in Frick, Switzerland. We compared the stable aggregate fraction of the soil and the bacterial...

Abstract: The aim of this study was investigate the effects of a low-protein, high-carbohydrate (LPHC) diet introduced to rats soon after weaning. The animals were distributed in the following groups: LPHC45: fed an LPHC diet (6%-protein, 74%-carbohydrate) for 45 days; C45: fed a control (C) diet (17%-protein, 63%-carbohydrate) for 45 days; R (Reverse): fed with LPHC for 15 days followed by C diet for 30 days. The LPHC45 group showed alterations in the energetic balance with an increase in brown adipose tissue, and in glucose tolerance, and lower final body weight, muscle mass and total protein in blood when compared with C45 group. The HOMA-IR index was similar between LPHC45 and C45 groups, but this parameter was lower in LPHC45 compared with R groups....

The development of methods to automatically determine the chemical nature of microplastics by FTIR-ATR spectra is an important challenge. A machine learning method, named k-nearest neighbors classification, has been applied on spectra of microplastics collected during Tara Expedition in the Mediterranean Sea (2014). To realize these tests, a learning database composed of 969 microplastic spectra has been created. Results show that the machine learning process is very efficient to identify spectra of classical polymers such as poly(ethylene), but also that the learning database must be enhanced with less common microplastic spectra. Finally, this method has been applied on more than 4000 spectra of unidentified microplastics. The verification protocol...

A meta‐analysis of fish behavioural reaction to underwater human presence

In an increasingly anthropic world, humans have profound impacts on the distribution and behaviour of marine fishes. The increased human presence has modified fishesf antipredator behavioural responses, and consequently flight decisions, as a function of their changed perceptions of risk. Understanding how fish react to human presence can help identify the most vulnerable functional groups/species and estimate impacts caused by human disturbance. Shoal and body size are known to influence fish flight initiation distance (FID; the distance between the predator and prey when the prey begins to escape); however, few studies attempt to test the moderators of these relationships. Here, we present a comprehensive meta]analysis evaluating FID of fish in...

ABSTRACT: Food security assurance to meet the demands of increased population growth requires a proportional increase in milk and meat production which, in turn, depends on animal nutrition. Assessing foliar application of micronutrients for production of substantive quantities of good quality forage must be a goal of modern, profit-oriented, sustainable agriculture and plants with better competitive ability as compared to weeds. This meta-analysis made a quantitative and qualitative analysis of the impact of foliar feeding of micronutrients (iron, zinc, copper, sulfur and boron) on forage crops under varying pedo-climatic conditions. Weighted and unweighted meta-analyses were performed on 139 studies to evaluate 19 independent variables (9 qualitative, 5...

For data-limited stocks (DLS), professional fishing data can be used as a potential source of information, especially in the absence of appropriate scientific survey, to understand abundance evolution under realistic hypothesis on resource catchability. This work focuses on a data-filtering approach, the selected fishing effort must reflect vessel activity that is least dependent on their technical characteristics and as stable as possible over time. The variable of interest is landing by fishing sequence (landing for a given gear, gear mesh, day and ICES statistical rectangle) called LPUE. In order to account for the abundance of the species, it was necessary to consider the discards. The method thus proceeds in 4 steps: (i) focus on LPUE variability and...

Autores: Cherri,Adriana Cristina; Vianna,Andrea Carla Gonçalves; Ramos,Rômulo Pimentel; Florentino,Helenice de Oliveira.
ABSTRACT: Brazil is the largest sugarcane producer in the world and the leader in the production of sugar and ethanol. Although sugarcane has become an important factor in the Brazilian economy, cultivation has presented many issues, for example, the problems due to burning before the manual harvest. The Brazilian authorities have approved a law that prohibits this practice and mechanized harvesting has thus become the most fitting approach. Given this development, areas for sugarcane plantation must be properly rebuilt to accommodate the new way of harvesting. The main characteristic demanded of sugarcane plots to use harvesting machines is that they must be rectangular. In the present paper, we propose a methodology for dividing the plantation area into...

ABSTRACT The aim of the present study was to propose a mixed model for a sensory analysis of four experiments with blends of different standards of quality, including the species Coffea Arabica L. and Coffea Canephora. Each experiment differed in the proportions used to formulate the blends and the concentrations used in preparing the beverages, these being 7% and 10% coffee powder for each 100 ml of water. The response variables under analysis were the sensory characteristics of the beverage found in an assessment made by a group of trained tasters, considering taste, bitterness and a final score. Each description followed a numerical rating scale of intensity that ranged from 0 to 10. The model was implemented using the least squares method; this led to...

Long-chain diols have been detected in a wide range of environments and have been used to reconstruct past environmental changes, however only a few long-term records exist to date. Here we reconstructed past environmental changes in the central Sea of Okhotsk over the last 1.5 million years, covering the Mid-Pleistocene Transition (MPT). Sea surface temperatures (SST) reconstructed using the Long-Chain Diol Index (LDI) reflects glacial/interglacial changes. However, when compared with other organic paleothermometers (Uk’37 and TEXL86) the LDI-SST is lower during interglacials and similar or higher during glacials, possibly suggesting a shift of diol production season during interglacials. The LDI-SST does not change in periodicity around the MPT as...

They are an example of an ecosystem based on chemosynthesis, where life is sustained by energy from chemicals rather than energy from sunlight. The discovery of an abundance of life around deep-sea hydrothermal vents emitting hot and toxic fluids demonstrated that animals and other organisms could thrive in the dark, cold and high-pressure deep oceans. Mussels are among the most studied animals found near hydrothermal vents. Scientists discovered that mussels rely on a close, living relationship—a “symbiosis”—with bacteria for their nutrition. In this symbiosis, bacteria use chemicals...

A new and improved electric fish finder with resources for printed circuit board fabrication
Provedor de dados: 83
Autores: Haag,Michael A.; Lambert,Jeffrey C.; Waddell,Joseph C.; Crampton,William G.R.
ABSTRACT We describe the circuit design, construction, and operation of a field-portable electric fish finder (an AC-coupled wide-band differential bio-amplifier with loudspeaker output). This device permits detection and monitoring of the electric organ discharges generated by neotropical gymnotiform fishes (as well as the mormyroid fishes of tropical Africa). Our design is modified from earlier versions to optimize detection performance and stability over a wider range of ambient water conductivity, including under conditions of extremely low conductivity (&lt; ca. 10 μScm-1). Our new electric fish finder design also incorporates complete waterproofing and longer battery autonomy. We provide Gerber and Eagle files made with the electronic design...

A new approach to recruitment overfishing diagnosis is presented. We hypothesize that condition of recruits should increase when recruitment failures are caused by fishing activity. This would be a consequence of the increase in trophic resource availability, because the population is smaller than that which the ecosystem could support. Temporal series of hake recruit condition were calculated from MEDITS survey data collected in Mediterranean geographical sub-areas (GSAs) 1, 6, 17 and 19 from 1994 to 2015. Multiple linear regressions were used to analyse the relationship between mean annual condition and abundance of recruits and climatic indices in each GSA. Significant correlations were only detected in GSA 6, where 69% of condition variability was...

A new cecidogenous species of many-plumed moth (Alucitidae) associated with Cordiera A. Rich. ex DC. (Rubiaceae) in the Brazilian Cerrado
Provedor de dados: 103
Autores: Moreira,Gilson R.P.; Pereira,Cristiano M.; Becker,Vitor O.; Specht,Alexandre; Gonçalves,Gislene L.
ABSTRACT Larvae of many-plumed moths (Alucitidae), especially in the world-wide genus Alucita Linnaeus, 1758 are known as borers or gall-inducers on flowers, fruits and shoots of a few dicotyledonous families, including Bignoniaceae, Caprifoliaceae and Rubiaceae. However, there is no study available on the biology of the monotypic, Neotropical genus Prymnotomis Meyrick, 1931 except for its original description that was based on a single male, the holotype of Prymnotomis crypsicroca Meyrick, 1931 from Espirito Santo, Brazil. We describe here a second species for this genus, Prymnotomis cecidicola sp. nov. whose larvae induce galls on Cordiera elliptica (Cham.) Kuntze (Rubiaceae), a dioecious plant with dimorphic inflorescences found in the Brazilian...

Abstract: In this paper, we introduce a new three-parameter distribution by compounding the Nadarajah-Haghighi and geometric distributions, which can be interpreted as a truncated Marshall-Olkin extended Weibull. The compounding procedure is based on the work by Marshall and Olkin 1997. We prove that the new distribution can be obtained as a compound model with mixing exponential distribution. It can have decreasing, increasing, upside-down bathtub, bathtub-shaped, constant and decreasing-increasing-decreasing failure rate functions depending on the values of the parameters. Some mathematical properties of the new distribution are studied including moments and quantile function. The maximum likelihood estimation procedure is discussed and a particle swarm...

A new definition of the South-East Madagascar Bloom and analysis of its variability
Provedor de dados: 5
Autores: Dilmahamod, Ahmad Fehmi; Penven, Pierrick; Aguiar gonzalez, B.; Reason, C. J. C.; Hermes, J. C.
The South‐East Madagascar Bloom occurs in an oligotrophic region of the South‐West Indian Ocean. Phase‐locked to austral summer, this sporadic feature exhibits substantial temporal and spatial variability. Several studies, with different hypotheses, have focused on the initiation mechanism triggering the bloom but none has been as yet clearly substantiated. With 19‐years of ocean colour dataset available as well as in‐situ measurements (Argo profiles), the time is ripe to review this feature. The bloom is characterized in a novel manner and a new bloom index is suggested, yielding 11 bloom years, including 3 major bloom years (1999, 2006 and 2008). Spatially, the bloom varies from a mean structure (22° S‐32° S; 50° E‐∼70°E) both zonally and meridionally. A...

A new device to autonomously feed individualized mantids on extended periods of time
Provedor de dados: 92
Autores: Scherrer,Marcus V.; Aguiar,Alexandre P.
ABSTRACT Mantises can live for many months, are naturally voracious, and feed invariably on live prey. Many species have a propensity for cannibalism and cannot be kept together for most of their life cycle, which makes large-scale rearing typically time-consuming, thus easily becoming prohibitive. This is particularly true for early instars, because they are the most abundant stage of a developmental cohort. Such limitation hinders research on Mantodea which depend on live individuals, such as behavior, physiology, ontogeny, and others. In this work, a simple, low-maintenance “self-service” device is described, which is greatly effective in reducing the time needed for keeping live, individual, small to medium-sized mantises. Trial and error usage and...

Provedor de dados: 103
Autores: Melo,Gabriel A.R.; Rosa,Brunno B.
ABSTRACT The first fossil species of the wasp genus Tracheliodes from Dominican amber is described. Tracheliodes grimaldii sp. nov. is based on a single female specimen exhibiting a somewhat generalized morphology compared to the extant fauna. While the new species resembles the Neotropical species in a few characters, it does not possess the many specialized features exhibited by this species group, especially those related to the female legs. This is the 4th genus and the 7th species of apoid wasps described from Dominican amber.

A new glandular Mimosa species from Southern Brazil and insights about its glandular trichomes micromorphology
Provedor de dados: 39
Autores: Silveira,Fernanda Schmidt; Vargas,Wanderleia de; Fortuna-Perez,Ana Paula; Miotto,Silvia Teresinha Sfoggia.
ABSTRACT Mimosa baptistae is a new species presenting stalked glandular trichomes that give it a glutinous appearance, mainly with respect to the leaflets. Furthermore, it is an aculeate species, with multijugate leaves, white stamens, and fruits also covered by glandular trichomes. A herbaria survey and fieldwork only recorded this species as occurring on sandstone outcrops of the city Caçapava do Sul, Brazil. The species may be confused with other species of Mimosa sect. Batocaulon ser. Stipellares such as M. bifurca, M. sobralii and M. lepidota. However, features such as absence/presence of aculei, stamens color, habitat, and flower features are useful for distinguishing them from the new species. Here, we provide notes on morphology, geographic...

A new, harmless, high-throughput endosperm-based DNA extraction method for wheat
Provedor de dados: 65
Autores: Ma,Zhihui; Wang,Yuquan; Wei,Wenhui; Ru,Zhengang.
ABSTRACT:  In this study, a non-destructive, high-throughput, endosperm-based DNA extraction method was developed. To verify the non-destructive nature of this method, a germination test was performed on 288 seeds after sampling their endosperm, which gave a seedling emergence rate that was higher (97.6%) than that of the control group (92%). To confirm the feasibility of the new method, DNA was extracted from plants of a BC1F2 population by two different methods, namely, from endosperm using our rapid, high-throughput method (ER-DNA) and from young leaves emerging from the same sampled seed using the CTAB method (LC-DNA). The ER-DNA was undetectable by agarose gel electrophoresis, but was found to be an adequate replacement for LC-DNA for the...

A new ‘horned’ Stenocercus from the highlands of southeastern Brazil, and redescription of Stenocercus tricristatus (Reptilia: Tropiduridae)
Provedor de dados: 103
Autores: Ávila-Pires,Teresa C. S.; Nogueira,Cristiano de C.; Martins,Marcio.
ABSTRACT A new species of the lizard genus Stenocercus Duméril &amp; Bibron, 1837 is described based on six specimens from Serra da Canastra, Minas Gerais, southeastern Brazil. Similar to S. tricristatus (Duméril, 1851), S. dumerilii (Steindachner, 1867), S. quinarius Nogueira &amp; Rodrigues, 2006, and S. squarrosus Nogueira &amp; Rodrigues, 2006, the new species has a pyramidal head and an enlarged, dorsally projected post-supraciliary scale, like a small horn. It is most similar to S. tricristatus, from which it differs in having a more elongated head in ventral view; a larger number of scales around midbody; a distinctly enlarged, smooth preauricular scale; and probably a larger body size. Moreover, the new species has distinctly keeled scales, with...

A new ocean SAR cross-spectral parameter: definition and directional property using the global Sentinel-1 measurements
Provedor de dados: 5
Autores: Li, Huimin; Chapron, Bertrand; Mouche, Alexis; Stopa, Justin.
Space‐borne synthetic aperture radar (SAR) measurements have already been proven to be invaluable in detecting and quantifying properties of ocean swell systems. With the improved spatial resolution, Sentinel‐1 wave mode measurements can further be extended towards shorter scale waves, i.e. within the surface wave equilibrium range. In this study, a new parameter is derived from filtering SAR image cross‐spectra around range‐traveling intermediate wind waves (wavelengths 15‐20 m). This parameter captures both the radar cross section variability and its time evolution. Given the dependence of intermediate waves on local wind field, this parameter is statistically documented to confirm its sensitivity to both wind speed and wind direction. Comparable to...

A new protodidelphid (Mammalia, Marsupialia, Didelphimorphia) from the Itaboraí Basin and its implications for the evolution of the Protodidelphidae
Provedor de dados: 42
Autores: CARNEIRO,LEONARDO M.
Abstract The Protodidelphidae was a group of marsupials that lived in Gondwana from the early to middle Eocene. Among South American faunas, the Itaboraí Basin calls attention by the presence of four genera and six species. Herein is described Bergqvistherium primigenia gen. et sp. nov., a new protodidelphid from the Itaboraí Basin - lower Eocene. This taxon differs from other protodidelphids in the smaller size, developed entocristid, less brachyo-bunoid adaptations, and entoconid more mesial than the hypoconid. These characters are recovered as plesiomorphies of the Protodidelphidae, supporting Bergqvistherium as an early-divergent lineage of this group. The Protodidelphidae fauna of the Itaboraí Basin is represented by less specialized “basal” taxa,...

A new rheological model for thixoelastic materials in subaqueous gravity driven flows
Provedor de dados: 5
Autores: Hermidas, Navid; Silva Jacinto, Ricardo; Eggenhuisen, Joris T.; Luthi, Stefan M.
A new viscoelastic constitutive model for subaqueous clay-rich gravity flows is presented. It is explained that for the materials which exhibit a minimum in their strain controlled flow curves the structure parameter must be a symmetric function of strain rate and stress. Therefore, the destruction of structure within the material is modeled using the dissipation energy. An expression for the elastic strain of the flowing structure is derived. The final set of equations can reproduce the viscosity bifurcation that clay suspensions may exhibit under a given load. This is explained to be important for prediction of the run-out distance of clay-rich gravity flows. The ability of the model to reproduce the general response of pasty materials to step stress and...

Autores: MELO,Efigenia de; FERREIRA,Carlos Alberto CID; GRIBEL,Rogério.
ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic...

A new species of Curculionichthys (Siluriformes: Loricariidae) from the north edge of the Brazilian Shield, lower Amazon basin
Provedor de dados: 83
Autores: Gamarra,Suelen P.; Calegari,Bárbara B.; Reis,Roberto E.
ABSTRACT A new species of Curculionichthys is described from the rio Curuá-Una basin, in the northern edge of the Brazilian Shield, State of Pará, Brazil. The new species is diagnosed from congeners by possessing a single rostral plate, by having darkened tooth-crowns, and by a series of morphometric and meristic data. A close examination of the species of Curculionichthys revealed the presence of hyperthrophied odontodes on both dorsal and ventral margins of the snout tip, which are illustrated by electronic microscopy. A discussion is provided on possible phylogenetic relationships of the new taxon. The new species is provisionally accessed as Least Concern (not threatened).

Provedor de dados: 5
Autores: Labrune, Céline; Lavesque, Nicolas; Bonifácio, Paulo; Hutchings, Pat.
A new species of Terebellidae, Pista colini sp. n., has been identified from the harbour of Banyuls-sur-Mer, north-western Mediterranean Sea. This new species was found in very high densities, exclusively in gravelly sand deposited manually, and was not found in the original source habitat of the gravel. This species is characterized by the colour of the ventral shields with pinkish anterior part and a blood red posterior part in live specimens, a pair of unequal-sized plumose branchiae inserted on segment II and anterior thoracic neuropodia with long-handled uncini. The presence of long-handled uncini even in the smallest specimens constitutes the major difference between Pista colini sp. n. and other Pista species with a single pair of branchiae such as...

Provedor de dados: 83
Autores: Garcia-Ayala,James R.; Benine,Ricardo C.
ABSTRACT A new species of Poptella is described from the Rio Juma, a tributary of the lower Rio Aripuanã, Rio Madeira basin, Amazonas, Brazil. The new species is distinguished from all congeners, except P. brevispina, by having a lower number of scale rows between the lateral line and dorsal-fin origin (7 vs. 8-10). The new species can be readily distinguished from P. brevispina by the lower number of branched dorsal-fin rays (9 vs. 10). This is the first description of a new species of Poptella since the revisionary study of the Stethaprioninae, published 30 years ago.

ABSTRACT Dihoplotermes, a previously monotypic genus, is now composed of two species. Dihoplotermes taurus sp. nov., a new Termitinae termite species, is illustrated and described based on morphological characters from soldiers, workers, and imago. The new species is distinguished from Dihoplotermes inusitatus Araujo by having a spine-like protuberance with blunt apex on the postmentum, the presence of a spine on the gizzard and the absence of dimorphic soldiers. Furthermore, the internal morphological characteristics of a Dihoplotermes worker are described for the first time. Both internal and external morphological characters were used to improve the characterization of the species.

A NOVEL RAISIN SEGMENTATION ALGORITHM BASED ON DEEP LEARNING AND MORPHOLOGICAL ANALYSIS
Provedor de dados: 70
Autores: Zhao,Yun; Guindo,Mahamed L.; Xu,Xing; Shi,Xiang; Sun,Miao; He,Yong.
ABSTRACT We propose a segmentation algorithm for raisin extraction. The proposed approach consists of the following aspects. Deep learning is used to predict the number of raisins in each connected region, and the shape features such as the roundness, area, X-axis value for the centroid, Y-axis value for the centroid, axis length and perimeter of each region will be used to establish the prediction model. Morphological analysis, based on edge parameters including the polar axis, polar angle and angular velocity, is applied to search for the suitable break points that are useful for identifying the dividing lines between two adjacent raisins. To make our segmentation more accurate, some machine-learning algorithms such as the random forest (RF), support...

Autores: Haji,Salih Omer; Yousif,Raghad Zuhair.
Abstract: Thyroid nodules are cell growths in the thyroid which might be for in one of two categories benign or malignant. Nodular thyroid disease is common and because of the associated risk of malignancy and hyper-function; these nodules have to be examined thoroughly. Hence diagnosing thyroid nodule malignancy in the early stage can mitigate the possibility of death. This paper presents an intelligent thyroid nodules malignancy diagnosis using texture information in run-length matrix derived from 2- level 2D wavelet transform bands (approximation and details). In this work, ANOVA test has been used to for feature selection to reduce for feature selection about 45 run-length features with and without wavelet generated, before feeding those features which...

Globally, vibrios represent an important and well-established group of bacterial foodborne pathogens. The European Commission (EC) mandated the Comite de European Normalisation (CEN) to undertake work to provide validation data for 15 methods in microbiology to support EC legislation. As part of this mandated work programme, merging of ISO/TS 21872–1:2007, which specifies a horizontal method for the detection of V. parahaemolyticus and V. cholerae, and ISO/TS 21872–2:2007, a similar horizontal method for the detection of potentially pathogenic vibrios other than V. cholerae and V. parahaemolyticus) was proposed. Both parts of ISO/TS 21872 utilized classical culture-based isolation techniques coupled with biochemical confirmation steps. The work also...

Anticipating future changes in marine social‐ecological systems (MSES) several decades into the future is essential in the context of accelerating global change. This is challenging in situations where actors do not share common understandings, practices, or visions about the future. We introduce a dedicated scenario method for the development of MSES scenarios in a participatory context. The objective is to allow different actors to jointly develop scenarios which contain their multiple visions of the future. The method starts from four perspectives: “fisheries management,” “ecosystem,” “ocean climate,” and “global context and governance” for which current status and recent trends are summarized. Contrasted scenarios about possible futures are elaborated...

ABSTRACT Advances in potter wasp systematics have been achieved recently, with classificatory changes resulting from analyses based upon large scale molecular datasets. For the Neotropics, recent hypotheses point to the occurrence of an exclusive clade recognized within the tribe Eumenini. In this group, several contributions regarding taxonomy and systematics have been proposed in the last five years, including the genus Alphamenes. This taxon contains seven described species whose distribution is exclusively Neotropical. Females are morphologically homogeneous, and characters related to copulatory organs are useful in male diagnosis. This contribution forms the first phylogenetic approach to include all species of Alphamenes, hence the first to strongly...

A Physiologically Structured Equation to Consider Quota Heterogeneity in the Droop Model
Provedor de dados: 5
Autores: Mairet, Francis; Baron, Regis.
The Droop model allows to represent microalgae growth limited by a nutrient, using a cell quota (also referred to as variable-yield) approach. Single-cell measurements have revealed quota heterogeneity in phytoplankton collected from field studies. Such heterogeneity can be due, among other factors, to spatial structure (e.g. in biogeochemical cycles in the ocean, or for photobioreactors connected in series). Nonetheless, quota heterogeneity is generally omitted in modelling studies, using an average quota approach, or included in size-structured or individual-based models. Here, we propose a distributed Droop equation to tackle this problem, considering subpopulation growth -in line with Droop macroscopic view- rather than cell division dynamics. We...

A predictive index based on environmental filters for the bioassessment of river basins without reference areas in Atlantic Forest biome, Brazil
Provedor de dados: 49
Autores: Souza,Natália Freitas de; Baptista,Darcílio Fernandes; Buss,Daniel Forsin.
Abstract: Biological assessments that use the reference condition approach are based on the concept of comparing a site's observed biology to sites where disturbance is minimal or absent. However, in many regions of the world, such areas are scarce or nonexistent. In this study, an alternative approach proposed by Chessman and Royal for bioassessment without reference areas based on environmental filters was tested in Brazil. This approach assumes that key environmental features act in the selection of potential colonists, from a regional pool of taxa, based on the ecological traits (tolerances) possessed by each taxon. We developed the approach by: 1) determining the regional pool, based on a large Atlantic Forest biome database; 2) selecting...

A predictive multimetric index based on macroinvetebrates for Atlantic Forest wadeable streams assessment
Provedor de dados: 49
Autores: Oliveira,Renata Bley da Silveira de; Mugnai,Riccardo; Pereira,Priscilla da Silva; Souza,Natália Freitas de; Baptista,Darcílio Fernandes.
Abstract: Multimetric Indices (MMIs) have been widely applied for ecological assessment in freshwater ecosystems. Most MMIs face difficulties when scaling up from small spatial scales because larger scales usually encompass great environmental variability. Covariance of anthropogenic pressures with natural environmental gradients can be a confounding factor in assessing biologic responses to anthropogenic pressures. This study presents the development and validation of a predictive multimetric index to assess the ecological condition of Atlantic Forest wadeable streams using benthic macroinvertebrates. To do so, we sampled 158 sites for the index development. We adjusted each biological metric to natural variation through multiple regression analyses...

Habitat dynamics interacting with species dispersal abilities could generate gradients in species diversity and prevalence of species traits when the latter are associated with species dispersal potential. Using a process‐based model of diversification constrained by a dispersal parameter, we simulated the interplay between reef habitat dynamics during the past 140 million years and dispersal, shaping lineage diversification history and assemblage composition globally. The emerging patterns from the simulations were compared to current prevalence of species traits related to dispersal for 6315 tropical reef fish species. We found a significant spatial congruence between the prevalence of simulated low dispersal values and areas with a large proportion of...

Autores: Silva,Orlando Monteiro da; Moreira,Felipe Dias Gomes.
Resumo: Esse estudo analisou a evolução dos custos totais do comércio bilateral do Brasil com os principais parceiros comerciais, no período de 1995 a 2012. Os custos totais do comércio foram divididos entre custos tarifários e não tarifários, para os setores de produtos manufaturados e agrícolas. Avaliou-se, também, os custos do comércio brasileiro no Mercosul e o efeito da sua redução sobre os fluxos do comércio bilateral. Os resultados mostraram uma diminuição contínua dos custos do comércio internacional e da importância relativa das tarifas comparadas às medidas não tarifárias. Os custos do comércio internacional foram maiores para os produtos agrícolas do que para os manufaturados, e aumentaram durante o “boom das commodities” (2002/07), evidenciando...

A Rapid and Reliable Method for Molecular Detection of Fusarium guttiforme, the Etiological Agent of Pineapple Fusariosis
Provedor de dados: 52
Autores: Carnielli-Queiroz,Lorena; Fernandes,Patricia Machado Bueno; Fernandes,Antônio Alberto Ribeiro; Ventura,José Aires.
Abstract Pineapple (Ananas comosus var. comosus) fusariosis is an economically important fungal disease affecting the plant and its fruit. A rapid and reliable diagnosis is the base of integrated disease management practices. Fusariosis has resulted in quarantines for pineapple products in Central America, Africa and Asia. Difficulties diagnosing and correctly identifying the fungus Fusarium guttiforme, agent of the pineapple fusariosis, have led to the search for new methodologies, and for this we developed a new reliable molecular method to detect it. For diagnostic purposes, real-time PCR of elongation factor gene 1-α (ef1) was used to rapidly, specifically and sensitively diagnose F. guttiforme. A pathogenicity test was conducted with slips of the...

ABSTRACT:  A 14-year-old female Dachshund was referred to a veterinary hospital with a history and signalment of head pressing, compulsive walking, and right circling. At ophthalmologic examination, a mature cataract and absence of photomotor reflex in the right eye were observed. The neurological exam revealed multifocal encephalic signs. At necropsy, a conical solid tan mass was observed involving the right optic nerve throughout its extension to the optic chiasm. Histopathological findings confirmed a retrobulbar papillary meningioma, considered rare and seldom included as differential diagnosis in patients with neurological signs.

Autores: Diesel,Jose Francisco; Ortiz,Mauro F.; Marinotti,Osvaldo; Vasconcelos,Ana Tereza R.; Loreto,Elgion L. S.
Abstract The mobilome, portion of the genome composed of transposable elements (TEs), of Anopheles darlingi was described together with the genome of this species. Here, this mobilome was revised using similarity and de novo search approaches. A total of 5.6% of the A. darlingi genome is derived of TEs. Class I gypsy and copia were the most abundant superfamilies, corresponding to 22.36% of the mobilome. Non-LTR elements of the R1 and Jockey superfamilies account for 11% of the TEs. Among Class II TEs, the mariner superfamily is the most abundant (16.01%). Approximately 87% of the A. darlingi mobilome consist of short, truncated and/or degenerated copies of TEs. Only three retrotransposons, two belonging to gypsy and one to copia superfamilies, are...

Abstract Antispastis Meyrick, 1926 is a poorly known genus of leaf-mining micromoths endemic to the Neotropics, with still uncertain taxonomic position within the Yponomeutoidea. In the present study, the egg, larva and pupa of A. clarkei Pastrana, previously known only from Argentina, are described and illustrated with the aid of optical and scanning electron microscopy. Data on life history, including histology of the mine, are also provided. Family placement of the genus is reassessed based on comparison of morphology and DNA sequences with closely related lineages. The larvae form blotch mines on the upper surface of Solanum L. (Solanaceae) leaves, feeding on palisade parenchyma in all instars. Pupation occurs outside the mine, in an inverted...

ABSTRACT The success of soil prediction by VIS-NIR-SWIR spectroscopy has led to considerable investment in large soil spectral libraries. The aims of this study were 1) to develop a soil VIS-NIR-SWIR spectroscopy approach using legacy soil samples to improve spectral soil information in a regional scale; (2) to compare six spectral preprocessing techniques; and (3) to compare the performance of linear and non-linear multivariate models for prediction of sand and clay content. A total of 1,534 legacy soil samples, stored by Epagri, were collected from agricultural areas in 2009 on a regional scale, covering 260 municipalities of Santa Catarina. Six spectral preprocessing techniques were applied and compared with reflectance spectra (control treatment) in...

Development of global ocean observing capacity for the biological EOVs is on the cusp of a step-change. Current capacity to automate data collection and processing and to integrate the resulting data streams with complementary data, openly available as FAIR data, is certain to dramatically increase the amount and quality of information and knowledge available to scientists and decision makers into the future. There is little doubt that scientists will continue to expand their understanding of what lives in the ocean, where it lives and how it is changing. However, whether this expanding information stream will inform policy and management or be incorporated into indicators for national reporting is more uncertain. Coordinated data collection including open...

Autores: Paull, John.
The present review of the Independent Review of the South Australian GM Food  Crop Moratorium (Anderson, 2019) reveals that the so-called Independent Review is not independent at all and thus it falls at the first hurdle. Kym Anderson is a long term vocal advocate of genetically modified crops and has expressed such views regularly over the past two decades. The Independent Review was commissioned by the South Australian Minister for Primary Industries and Regional Development. There were 216 public submissions, of these, 78% (n=168) were for retaining the existing Moratorium, 18% (n=39) were for scrapping the Moratorium, and 4% (n=8) were undecided. 100% of the food available in Australian supermarkets is GM-free which mirrors the sentiments of Australian...

ABSTRACT The Mylodontidae Scelidotheriinae (Mammalia, Xenarthra, Tardigrada) are a diversified clade of South American fossil ground sloths, with a wide geographic distribution, especially in high and middle latitudes. According to the last revision, the Quaternary diversity includes the genera Scelidotherium, Catonyx, and Valgipes. The clade Scelidotheriinae is well represented in the Pleistocene of the Tarija-Padcaya basin, and the first mention of these ground sloths correspond to the middle of the XIX Century. Since then, several species (i.e., Scelidotherium tarijensis, Scelidodon tarijensis, Scelidotherium capellini) have been reported as inhabiting the Tarija-Padcaya basin during the Pleistocene. Despite the abundance of fossil records of...

Autores: Mahmoudian-sani,Mohammad-Reza; Sheikhshabani,SomayehHashemi; Mirfakhar,Farzaneh Sadat; Asgharzade,Samira.
Hearing loss induced by chemotherapy and acoustic trauma is mainly associated with two factors, free radical formation and apoptosis pathway activation. Despite numerous efforts on reducing the effects of these factors, no definite strategy is still determined to interfere with and control these processes. In recent studies, various protective agents, including antioxidants have been used on animal models, to inhibit the formation of free radicals thus improving hearing loss.In this review article we will discuss the role of traditional herbal medicine in treatment of noise/drug induced hearing loss, focusing on medicinal plants’ active substances,as well as their mechanisms of action in reducing or preventing the formation of free radicals thus increasing...

A row cropping system with cover crops for balancing weed and soil fertility management in organic cereal production
Provedor de dados: 21
Autores: Phan, Hong TT; Thorup-Kristensen, Kristian.
This manuscript shows the result from testing the new row cropping system for its ability to produce a balanced combination of inter-row hoeing and undersown cover crop in order to obtain a sufficient N supply and an effective weed control as well as to identify optimal sowing time for high biomass production and cover crop species suited for late undersowing. The new system produced a sufficient N supply and an acceptable weed control effect, leading to an improvement in the subsequent crop yield. Yield in this system is potentially improved further because some managements are suggested to increase its weed control effect, especially for the perennial creeping thistle cirsium arvense.

Esta semana, o Prosa Rural fala sobre a saúde do solo e o uso de bioindicadores nas análises de solo. Até recentemente, a presença de bioindicadores que ajudassem a avaliar a saúde dos solos não fazia parte das rotinas de análises de solo. Pesquisadores da Embrapa desenvolveram a tecnologia da bioanálise de solo que vai preencher essa lacuna. A partir das próximas safras, além de poderem solicitar aos laboratórios análises químicas e físicas dos solos, os produtores também vão poder ter acesso a informações referentes a maquinaria biológica do solo, constituída por microrganismos, raízes e fauna. Quem explica esse assunto é a pesquisadora da Embrapa Cerrados, Ieda Mendes.

Farmers are important actors for regional development and biodiversity protection. Agri-environment-climate measures (AECM) are therefore a central tool of the European Union to support its biodiversity conservation policy. AECM generally reward farmers for fulfilling predefined management actions or avoiding specific practices. In contrast, result oriented AECM are intended to reward farmers for the outcome of nature friendly management practices. This approach gives more flexibility in management and hence promotes farmers engagement and autonomy. Besides educational activities and agricultural advisory services farmers need user friendly tools to assess biodiversity in order to meet result oriented AECM. Thus, we present a biodiversity assessment scheme...

A simplified model for the baroclinic and barotropic ocean response to moving tropical cyclones: 1. Satellite Observations
Provedor de dados: 5
Autores: Kudryavtsev, Vladimir; Monzikova, Anna; Combot, Clement; Chapron, Bertrand; Reul, Nicolas; Quilfen, Yves.
Changes of sea surface temperature (SST) and height (SSH) derived from 20‐days passive microwave and altimeter measurements for three tropical cyclones (TCs), Jimena, Ignacio and Kilo, during the 2015 Pacific hurricane season, sampling different stages of intensification, wind speeds, radii, Coriolis parameter, translation velocities, and ocean stratification conditions, are reported and analyzed. As triggered along the path of moving TCs, very large interior ocean displacements can occur to leave prominent SSH anomalies in the TC wake. Resulting surface depressions can reach.3‐.5 m, depending upon size, translation speed, and ocean stratification conditions. These signatures can be quite persistent, i.e. more than few weeks, to possibly be intercepted...

A simplified model for the baroclinic and barotropic ocean response to moving tropical cyclones: 2. Model and Simulations
Provedor de dados: 5
Autores: Kudryavtsev, Vladimir; Monzikova, Anna; Combot, Clement; Chapron, Bertrand; Reul, Nicolas.
A simplified analytical model is developed to describe the baroclinic and barotropic ocean response to moving Tropical cyclones (TC) and their associated pycnocline erosions. The model builds on classical mixed layer (ML) models and linear models of ocean response to transient events. As suggested, disturbances of the upper ocean stratification caused by the ML development shall not strongly impact the dynamics of baroclinic modes. Accordingly, the baroclinic response can be estimated using the pre‐storm ocean stratification condition. To the contrary, the ML is strongly coupled with these interior motions, through the TC‐induced upwelling response which affects the entrainment velocity. The ML temperature is then strongly dependent on the local...

Because of the relatively long growing cycle and the high cost of research into turkey production and nutrition, the potential benefits from modelling growth in this avian species are considerable. Though there are many studies aimed at evaluating animal growth models, the number of studies targeting growth models in turkeys is quite limited. In this paper we present a sinusoidal function to describe the evolution of growth in turkeys as a function of time based on data published by Aviagen. The new function was evaluated with regard to its ability to describe the relationship between body weight and age in turkeys and was compared to four standard growth functions: the Gompertz, logistic, Lopez, and Richards. The results of this study show that the new...

Macroautophagy is a mechanism that is involved in various cellular processes, including cellular homeostasis and innate immunity. This pathway has been described in organisms ranging in complexity from yeasts to mammals, and recent results indicate that it occurs in the mantle of the Pacific oyster, Crassostrea gigas. However, the autophagy pathway has never been explored in the hemocytes of C. gigas, which are the main effectors of its immune system and thus play a key role in the defence of the Pacific oyster against pathogens. To investigate autophagy in oyster hemocytes, tools currently used to monitor this mechanism in mammals, including flow cytometry, fluorescent microscopy and transmission electron microscopy, were adapted and applied to the...

Autores: ALBERTINI,MARCELO K.; BACKES,ANDRÉ R.; SÁ,ADRIANO L. DE.
Abstract: The average faculty productivity have been described as a rapid rise-short peak-gradual decline pattern. Way et al. (2017) have studied this pattern for faculty careers in Computer Science in North America using a piecewise linear model. In this paper, we use a similar methodology and study trajectories (N = 20655) of the Brazilian Computer Science community. First, we have evaluated how the median publication count of researchers is related to institution prestige and public vs. private administration. Second, we have studied how the annual publication rates have increased and its variation according to prestige ranks of institutions. Third, we have found the average trajectory can indeed be described as the canonical rapid increase and slower...

Autores: Souza,Aracele Maria de; Resende,Sarah Stela; Sousa,Taís Nóbrega de; Brito,Cristiana Ferreira Alves de.
Abstract The genetic background of the Brazilian population is mainly characterized by three parental populations: European, African, and Native American. The aim of this study was to overview the genetic ancestry estimates for different Brazilian geographic regions and analyze factors involved in these estimates. In this systematic scoping review were included 51 studies, comprehending 81 populations of 19 states from five regions of Brazil. To reduce the potential of bias from studies with different sampling methods, we calculated the mean genetic ancestry weighted by the number of individuals. The weighted mean proportions of European, African, and Native American ancestries were 68.1%, 19.6%, and 11.6%, respectively. At the regional level, the highest...

Provedor de dados: 39
Autores: Eggers,Lilian; Marchioretto,Rafaella; Souza-Chies,Tatiana T.; Chauveau,Olivier.
ABSTRACT A taxonomic synopsis of Cypella (Iridaceae) in Brazil is presented with recognition of 16 species, two of them represented by two subspecies. An identification key to the taxa is provided and species are described and illustrated. New synonyms are indicated, and eight lectotypes, two epitypes and one neotype are designated. Results include distribution, habitat, phenology, conservation status, notes and examined specimens of all taxa, as well as comments on dubious and misused names. The resulting framework revealed that most of the Brazilian species of Cypella occur in the state of Rio Grande do Sul and in the Pampa Biome, although Río de la Plata grasslands (RPG) is the most species-rich biogeographic unit of the genus.

A taxonomical study of benthic Prorocentrum species (Prorocentrales, Dinophyceae) from Anse Dufour (Martinique Island, eastern Caribbean Sea)
Provedor de dados: 5
Autores: Chomérat, Nicolas; Bilien, Gwenael; Zentz, Frédéric.
About 30 benthic Prorocentrum species have been described, some of which producing okadaic acid and derivatives involved in diarrhetic shellfish poisoning. The western Caribbean has been extensively studied for benthic dinoflagellates associated with ciguatera, and fifteen Prorocentrum species were described from mangroves and coral reefs of Belize. In contrast, no study reported the diversity of this genus in the Eastern Caribbean, especially in the Lesser Antilles. This study adds to the biodiversity knowledge in Martinique Island by investigating one site of the Caribbean coast from 2010 to 2017. Sediment samples were collected each year in March and studied taxonomically. Identification was realized morphologically by scanning electron microscopy,...

A Three‐way Balance in The Beaufort Gyre: The Ice‐Ocean Governor, Wind Stress, and Eddy Diffusivity
Provedor de dados: 5
Autores: Doddridge, Edward W.; Meneghello, Gianluca; Marshall, John; Scott, Jon; Lique, Camille.
The Beaufort Gyre (BG) is a large anticyclonic circulation in the Arctic Ocean. Its strength is directly related to the halocline depth, and therefore also to the storage of freshwater. It has recently been proposed that the equilibrium state of the BG is set by the Ice‐Ocean Governor, a negative feedback between surface currents and ice‐ocean stress, rather than a balance between lateral mesoscale eddy fluxes and surface Ekman pumping. However, mesoscale eddies are present in the Arctic Ocean; it is therefore important to extend the Ice‐Ocean Governor theory to include lateral fluxes due to mesoscale eddies. Here, a non‐linear ordinary differential equation is derived that represents the effects of wind stress, the Ice‐Ocean Governor, and eddy fluxes....

A two-dimensional analytical model of vertical water entry for asymmetric bodies with flow separation
Provedor de dados: 5
Autores: Hascoët, Romain; Jacques, Nicolas; Scolan, Yves-marie; Tassin, Alan.
The vertical water entry of asymmetric two-dimensional bodies with flow separation is considered. As long as there is no flow separation, linearised Wagner's theory combined with the modified Logvinovich model has been shown to provide computationally fast and reliable estimates of slamming loads during water entry. Tassin et al. [11] introduced the fictitious body continuation (FBC) concept as a way to extend the use of Wagner's model to separated flow configurations, but they only considered symmetric bodies. In the present study, we investigate the ability of the FBC concept to provide accurate estimates of slamming loads for asymmetric bodies. In this case, flow separation may not occur simultaneously on both sides of the body. During an intermediate...

ABSTRACT Lichens play a key role in natural ecosystems, as they can function as primary producers, recycle minerals and fix nitrogen. Despite their environmental importance, little is known about lichen ecology in Brazil, and especially about how abiotic factors may influence their spatial distribution. In this study, we aimed to verify how the cover and richness of corticolous lichens on Araucaria angustifolia trunks vary between two different habitats (Forest and Grassland). The photoquadrat sampling method was applied to A. angustifolia trunks. The Coral Point Count software with Excel extensions (CPCe) was used to analyze photographs for lichen cover and richness. Additionally, a redundancy analysis was conducted to estimate how five abiotic and two...

ABSTRACT Equine piroplasmosis is a tick-borne disease caused by the protozoan parasites Babesia caballi and Theileria equi. We report a case of abortion in association with transplacental Theileria equi infection in a mare from the State of Espírito Santo, southeast Brazil. An apparently healthy mare aborted at the tenth month of gestation. At necropsy, the subcutaneous tissue, skeletal muscles, and visible mucosae of the aborted fetus were pale, and there was moderate hydrothorax and marked splenomegaly. Microscopic findings included splenic lymphoid hyperplasia and nephrosis. Merozoite-infected erythrocytes were found within blood vessels of all organs examined and were most numerous in the brain. DNA extracted from the spleen, liver, kidney, and thymus...

ABSTRACT Seed germination is an important step for plants without vegetative propagation and is a physiological process that begins with specific environmental cues resulting in biochemical responses. Breaking-dormancy is necessary to study germination in dormant seeds with asynchronous germination. We investigated the processes of breaking dormancy and germination of Butia capitata (Arecaceae) seeds, in which germination is slow and asynchronous, by operculum removal. This treatment increased germination of B. capitata to 90 %. Embryos of dry, imbibed, 24-hours post-operculum removal and early-germinated seeds were collected for biochemical analysis of the following: quantification of abscisic acid (ABA) and hydrogen peroxide (H2O2), activities of...

Marine resources stewardships are progressively becoming more receptive to an effective incorporation of both ecosystem and environmental complexities into the analytical frameworks of fisheries assessment. Understanding and predicting marine fish production for spatially and demographically complex populations in changing environmental conditions is however still a difficult task. Indeed, fisheries assessment is mostly based on deterministic models that lack realistic parameterizations of the intricate biological and physical processes shaping recruitment, a cornerstone in population dynamics. We use here a large metapopulation of a harvested fish, the European hake (Merluccius merluccius), managed across transnational boundaries in the northwestern...

Many farm sustainability assessments use multi-criteria methods for aggregating indicators based on performance scores and importance weights. One of these is the SMART-Farm Tool, which measures the degree of goal achievement of farms across 327 indicators nested within 4 sustainability dimensions, 21 themes and 58 sub-themes of the FAO-SAFA Guidelines (Sustainability Assessment of Food and Agriculture). This study aims to improve the empirical foundation of the SMART-Farm Tool by (i) evaluating the uncertainty of indicator weights obtained via expert opinion and (ii) integrating this uncertainty into SMART assessment results. An adapted Delphi process was implemented, involving a group of 67 experts from 21 countries divided into thematic and regional...

Accumulation and dispersion dynamics of mud and sand particles in a continental shelf under estuarine influence: a numerical modelling analysis (Gironde, France)
Provedor de dados: 5
Autores: Diaz, Melanie; Grasso, Florent; Le Hir, Pierre; Caillaud, Matthieu; Thouvenin, Benedicte.
Coastal environments are directly influenced by terrigenous inputs coming from rivers through estuaries. Quantifying the amount of nutrients and contaminants brought by sediments from continental areas to the sea is of major interest for marine resource protection. The complexity of the intra-estuarine dynamics, associated with the strong variability of meteorological forcing makes it difficult to quantify the residence time of particles within the estuary and the accumulation and dispersion areas offshore the mouth. Moreover, the dynamics of fine sediment trapping areas in the adjacent continental shelf (e.g. temporary or permanent storage such as the “West-Gironde Mud Patch” (WGMP) ) remains extremely challenging to address. Based on a realistic...

Provedor de dados: 56
Autores: Li,Min; Kong,Yan; Chen,Hongcun; Chu,Aiqin; Song,Guiqi; Cui,Yan.
Sarcopenia remains poorly managed in clinical practice due to the lack of simple and accurate screening tools. This study aimed to identify the cutoff values of the SARC-F questionnaire and Ishii's score using the variables age, grip strength, and calf circumference in older inpatients in China to compare the accuracy of the two methods and to explore their predictive ability for adverse outcomes (rehospitalization, falls, fracture, and death). Hospitalized patients (n=138) aged ≥60 years were included. The accuracy of the two tools was evaluated using the reference diagnosis recommended by the Asian Working Group on Sarcopenia (assessing patients with measurements of muscle mass, handgrip strength, and usual gait speed). Follow-up data were obtained by...

Autores: Avellar-Costa,Pedro; Santos,Danielle Cabral dos; Lange,Carla Christine; Laport,Marinella Silva; Brito,Maria Aparecida Vasconcelos Paiva; Rossi,Ciro César; Giambiagi-deMarval,Marcia.
ABSTRACT:  We compared the potential of routine techniques used for the identification of Staphylococcus species, aiming to evaluate their accuracy in the detection of 43 Staphylococcus chromogenes strains isolated from bovine mastitis that, despite being a coagulase-negative species, are able to clot plasma. These strains could be mistakenly suspected to be S. aureus and lead to an unappropriated treatment of the disease. MALDI-TOF, PCR-RFLP of the chaperonine gene groEL, and sequencing of the 16S rRNA and elongation factor Tu gene tuf were employed. Results from the four methods were coincident for only half of the strains because of the low accuracy of the groEL PCR-RFLP (51.2% accuracy). Even though all the sequencing results were identical, the high...

Autores: Santos,Wedisson Oliveira; Mattiello,Edson Marcio; Barreto,Matheus Sampaio Carneiro; Cantarutti,Reinaldo Bertola.
ABSTRACT: There are several globally accepted methods to chemically characterize P-fertilizers, but not all are suitable to predict the agronomic efficiency of the P sources in terms of plant nutrition. Our aim was to investigate the performance of P extractors for fertilizers, investigating the consistency of different methods for P sources of varying properties and the related plant responses. The experiment was carried out in a greenhouse, using corn as a model plant. Phosphorus values extractable in water, 2 % citric acid, 2 % formic acid, ammonium neutral citrate + water, and acid ammonium citrate were evaluated for eight P fertilizers of varied solubility and correlated with P uptake by corn. The extractors citric acid and formic acid recovered no...

Acoustic accelerometry reveals diel activity patterns in premigratory Port Jackson sharks
Provedor de dados: 5
Autores: Kadar, Julianna; Ladds, Monique; Mourier, Johann; Day, Joanna; Brown, Culum.
Distinguishing the factors that influence activity within a species advances understanding of their behavior and ecology. Continuous observation in the marine environment is not feasible but biotelemetry devices provide an opportunity for detailed analysis of movements and activity patterns. This study investigated the detail that calibration of accelerometers measuring root mean square (RMS) acceleration with video footage can add to understanding the activity patterns of male and female Port Jackson sharks (Heterodontus portusjacksoni) in a captive environment. Linear regression was used to relate RMS acceleration output to time‐matched behavior captured on video to quantify diel activity patterns. To validate captive data, diel patterns from captive...

Acquiring plant features with optical sensing devices in an organic strip-cropping system
Provedor de dados: 21
Autores: Krus, Anne; van Apeldoorn, Dirk; Valero, Constantino; Ramirez, José Juan.
There is an increasing market for organic agriculture (Golijan &amp; Popovi\vs, 2016). However, the lack of attention for biodiversity and soil fertility of current practices is a pressing issue. The SUREVEG project (CORE Organic Cofund, 2018) therefore looks at strip-cropping in organic production and its implementation in intensive farming to improve soil fertility and biodiversity throughout Europe. The aim is to enhance resilience (Wojtkowski, 2008), system sustainability, local nutrient recycling, and soil carbon storage (Wang, Li &amp; Alva, 2010) among others. To counteract the additional labour of a multi-crop system, a robotic tool is proposed, which will operate upside down suspended from a wide-span mobile carriage. Within the project framework,...

Autores: Passos Neto,Oscar Pacheco; Santos,André Bezerra dos; Silva,José Roberto Feitosa; Mota,Suetônio Bastos.
ABSTRACT Endocrine disruptors are exogenous substances that can impair one or more functions of the endocrine system and cause adverse effects to the health of an intact organism. The main goal of this study was to evaluate the effect of the endocrine disruptors 17β-estradiol (E2) and 17α-ethinyl estradiol (EE2) on the sexual differentiation of Nile tilapia during spawning. Six treatments and one control with three replications, totalizing 21 experimental units, were assessed in a completely randomized design. Hormones were dosed at concentrations of 250, 500, and 1,000 ng L−1 (treatments E2-250, E2-500, E2-1,000, EE2-250, EE2-500, and EE2-1,000). Exposure to hormones occurred during the first 28 days of life. After this period, water was completely...

Many social-ecological system(SES)-based approaches have been proposed to address environmental problems. Most social-ecological frameworks developed to date, however, lack clear operational linkages between humans and nature to efficiently guide SESs toward resilience. A conceptual framework designed to be operational is therefore necessary, as well as a network of research platforms with which to apply it. We defined explicit coupling processes that can be used as leverages to pilot an SES toward sustainability. We proposed to formalize an SES as a dynamic entity composed of two coupling interfaces, i.e., adaptive management and ecosystem services, both set within a landscape context to provide an actionable framework. These interfaces describe the way...

Autores: Malagodi-Braga, Kátia Sampaio; Moriconi, Waldemore; Queiroga, Joel Leandro de; Urchei, Mário Artemio; Pazianotto, Ricardo Antônio Almeida; Roncon, Kenny.
Trigona spinipes Fabricius (Apidae: Meliponini), is a common stingless bee widely seen in urban and rural areas in Brazil, popularly known as irapuá, arapuá or bee-dog. Although these bees are considered pollinators of some cultivated plants, they are better known for the damage they cause in different crops. During experimental agroecological cultivation of Artemisia (Artemisia annua Linn, Asteraceae), in Jaguariúna (SP, Brazil), stingless bees Trigona spinipes (Fabricius) were observed sucking phloem sap directly from the plant, a phenomenon not yet described in scientific literature. This study aimed to register and describe the phloem sap-sucking behavior performed by T. spinipes for the first time, as well as to assess the potential impact of this...

Provedor de dados: 103
Autores: Back,Janaína P.; Suzin,Adriane; Aguiar,Lucas M.
ABSTRACT Constant changes in natural environments impose challenges to wild animal populations, especially those that depend on social life. We gathered data on the activity budget and social interactions of a capuchin monkey (Sapajus sp.) group of 17 individuals confined to an urban green area receiving human food supplementation. We observed the capuchins between 7:00 am and 5:00 pm, three days a month, between January 2012 and June 2013 (total of 530 hours of direct observations). We collected 15,208 behavioral records through instantaneous scan sampling and 2,538 events of social interaction in an adapted version of the “all occurrences” method. Activity budget of capuchins was dominated by traveling (42%) and foraging (38%), followed by feeding (10%),...

Actual evapotranspiration and crop coefficient of sweet orange during the initial development phase in the Rio Largo region, Alagoas
Provedor de dados: 65
Autores: Silva,Ricardo Barros; Souza,José Leonaldo de; Ferreira Júnior,Ricardo Araújo; Santos,Marcos Alex dos; Souza,Renan Cantalice de; Santos,Wellington Manoel dos.
ABSTRACT:  Determining actual crop evapotranspiration (ETa) is paramount for irrigation management. The principal measurement methods and physical models generally require crop and weather data that are not readily available. We determined the crop coefficient (Kc) of sweet oranges during the initial development stage and evaluated the performance of the Poulovassilis semi-empirical model coupled with a simple soil water balance for estimating the ETa. The ETa was inferred from the variation in the soil water content over time, measured by time-domain reflectometry. In the Poulovassilis model, the ETa is obtained by multiplying the crop evapotranspiration (ETc) by an adjustment coefficient (ca), which accounts for a reduction in the evapotranspiration...

Acute toxicity of nitrate in Litopenaeus vannamei juveniles at low salinity levels
Provedor de dados: 65
Autores: Alves Neto,Inácio; Brandão,Hellyjúnyor; Furtado,Plínio Schmidt; Wasielesky Jr,Wilson.
ABSTRACT: Different technologies have been developed to improve the performance of Litopenaeus vannamei in low salinity, mainly in super-intensive systems like recirculation and BFT (Biofloc Technology System) systems. However, there is an accumulation of toxic nitrogenous compounds to the shrimps such as nitrate, that at high concentrations and depending on the salinity of the culture water can be lethal. Acute toxicity tests allow to analyze the relationship between the compound and other abiotic or biotic variables. The aim of this research was to determine the acute toxicity and safety level of nitrate (N-NO3 -) for juveniles of L. vannamei at salinities of 5 and 10g.L-1. For salinity of 5g.L-1, a control and 5 treatments were tested, with nitrate...

ABSTRACT In maize breeding programs conducted by private companies, it is common to perform the product advanced trials (PAT) in several cultivation environments in order to better recommend the new hybrids, as well as to provide opportunities for the farmers to evaluate their products. The aim of this study was to describe the adaptability and stability of maize hybrids from unreplicated PATs using a multivariate approach combined with univariate methods. We considered the grain yield data of twelve maize hybrids evaluated in a PATs network conducted by the company DuPont Pioneer in 80 cultivation environments in the states of Minas Gerais and Goias, in second-crop of 2014. The AMMI analysis was employed and additionally we applied the methods based on...

Autores: Studnicki,Marcin; Derejko,Adriana; Wójcik-Gront,Elżbieta; Kosma,Michał.
ABSTRACT: Multi-environment trials are commonly used to assess cultivar adaptation patterns under different environmental conditions and to help make effective cultivar recommendations for growers. An example of a multi-environment trial system used for cultivar recommendations is the Polish Post-registration Variety Testing System. A common approach in cultivar recommendations is to evaluate the adaptability of cultivars across, or for, specific trial locations. However, the locations of the trials and the fields where a farmer will grow a crop are hardly ever in the same place. Therefore, it would be better to group the trial locations into regions and give recommendations for the whole region. The aim of this study is to evaluate the grain yield...

ADDITION OF BOILER CHARCOAL WASTE TO COMPOST FOR USE AS SUBSTRATE FOR VEGETABLE SEEDLINGS
Provedor de dados: 70
Autores: Lorin,Higor E. F.; Costa,Mônica S. S. de M.; Chiarelotto,Maico; Santos,Francielly T. dos; Costa,Luiz A. de M.
ABSTRACT The recovery of waste from the broiler production chain (BPC) is consistent with the principles of a circular economy. Besides turning waste into organic compost, its use as substrate for the production of vegetable seedlings further increases its economic value. However, it is necessary to adapt its characteristics to enable its use as substrate. To this end, the addition of boiler remnant charcoal wastes (BCW), another type of waste generated in the BPC, to the organic compost resulting from the composting of BPC waste with different bulking agents (BAs) was studied. The addition of BCW to agro-industrial compost reduced the electrical conductivity (EC) of substrates. Multiple linear regression showed that, of the 13 variables (physical,...

ABSTRACT A study was conducted to evaluate the effect of chlorogenic acid (ChA) added pre-cooling and its combination with caffeine added during warming on cooled-stored boar semen parameters. Ten ejaculates were diluted in commercial extender with or without 4.5mg/ml ChA and stored at 15°C. After 0, 24 and 72 hours of storage, aliquots of these doses were taken and incubated at 37°C in the presence or absence of 8.0mM caffeine. Semen quality was evaluated after 10 and 120 minutes of incubation. The ChA increased (P &lt;0.01) the sperm motility, viability, acrosomal integrity and the percentage of spermatozoa with high mitochondrial activity (PMHA), however, decreased (P &lt;0.01) the malondialdehyde (MDA) concentration. Caffeine increased (P&lt;0.05) the...

Provedor de dados: 42
Autores: PÉLLICO NETTO,SYLVIO; BEHLING,ALEXANDRE.
Abstract: This study deals with the subject biomass estimation. The objective was to achieve the additivity of tree biomass components, which is defined as the compatibility among the component predictions and total tree biomass, using ratio estimates. The biomass estimation model was applied to black wattle trees in forest stands, which include a sample of 670 trees in an age range of 1 to 10.75 years. The adjusted model, in which the total biomass, or sum of predicted components, is a function of the stem volume multiplied by the Scalar Coefficients Proxy of Density, proved to be of great interest for biomass estimation and consistent when compared to the results obtained by WNSUR estimates (traditional method). The natural additivity of the tree biomass...

RESUMO Em seres humanos, a adiponectinemia está associada à obesidade e ao risco aumentado a uma ampla variedade de cânceres. Embora o papel dessa adipocina esteja bem documentado na patogênese do câncer em humanos, tal associação permanece a ser determinada em cães. Nesses animais, a relação da adiponectina com a carcinogênese parece ser ainda meramente especulativa. Nesse contexto, buscou-se nesta investigação comparar os níveis séricos de adiponectina em fêmeas hígidas e em portadoras de carcinomas mamários com diagnóstico histopatológico de carcinoma mamário tubular simples estágio 4, com comprometimento de linfonodos, porém sem metástases a distância detectadas. Foi observado que as cadelas diagnosticadas com carcinoma mamário tiveram níveis séricos...

High caloric intake promotes chronic inflammation, insulin resistance, and chronic diseases such as type-2 diabetes, which may be prevented by food restriction (FR). The effect of FR on expression of pro-inflammatory and anti-inflammatory genes in adipose tissue, liver, muscle, and brain was compared. Male Swiss mice were submitted to FR (FR group) or had free access to food (control group) during 56 days. The liver, gastrocnemius muscle, brain, and epididymal white adipose tissue (WAT) were collected for analysis of gene expressions. FR attenuated inflammation in the liver, brain, and gastrocnemius muscle but did not markedly change inflammatory gene expression in epididymal WAT. We concluded that adipose tissue was less responsive to FR in terms of gene...

This work investigated adult-mediated connectivity and spatial population structure of sardine in the European Atlantic waters. The spatial and temporal progress of cohorts was modelled using abundance-at-age survey data by area in the period 2000 to 2016, covering the region from the northern Bay of Biscay to the eastern Gulf of Cadiz. A novel methodology was used to calculate indices of cohort movement between areas. Movement was relatively low between three large regions, the Bay of Biscay, the northern Spanish and Portuguese waters and the Gulf of Cadiz, each hosting a recruitment hotspot. On the other hand, one half of the sardines recruited in North Portugal and a quarter of those recruited in Southwest Portugal moved to northern Spanish waters and...

Advanced method for sea ice concentration retrieval from satellite microwave radiometer measurements at frequencies near 90 GHz
Provedor de dados: 5
Autores: Zabolotskikh, E.v.; Balashova, E.a.; Chapron, Bertrand.
An advanced method for sea ice concentration retrieval from satellite microwave radiometer measurements at frequencies near 90 GHz is presented. The method is based on the new approach for the determination of the tie points ― the polarization differences (PD) of the brightness temperatures (TB) of the ocean-atmosphere system (PDW) and the sea ice-atmosphere system microwave radiation (PDSI). The approach is based on the results of physical modeling of the sea ice – ocean – atmosphere TB and the analysis of the measurements of the Advanced Microwave Scanning Radiometer 2 (AMSR2) in the Arctic region. The TB simulation is carried out for the whole ranges of the Arctic atmospheric conditions and sea ice and ocean parameters. The method of sea ice...

Provedor de dados: 75
Autores: Cardoso,Jean Carlos; Oliveira,Maria Eduarda BS de; Cardoso,Fernanda de CI.
ABSTRACT The production of secondary metabolites from medicinal plants, also called Plant-Derived Medicinal Compounds (PDMC), is gaining ground in the last decade. Concomitant to the increase in the knowledge about pharmacological properties of these compounds, horticultural plants are becoming the most important, sustainable and low-cost biomass source to obtain high-complex PDMCs to be used as medicaments. Biotechnological tools, including plant cell and tissue culture and plant genetic transformation, are increasingly being employed to produce high quality and rare PDMC under in vitro conditions. The proper use of these technologies requires studies in organogenesis to allow for better control of in vitro plant development and, thus, to the production...

Abstract  Coconut palm (Cocos nucifera L.) is one of the most important tropical species used by man, known as “tree of life”. In recent decades, with the expansion of coconut growing areas, limitations such as the occurrence of pests, uniformity of crops, adaptation to different ecosystems and others have affected the production and longevity of coconut trees. This review describes the major advances in propagation techniques of coconut palm, conventionally, by seeds and through plant tissue culture techniques from the mid-twentieth century onwards, as well as phytosanitary aspects that should be considered to mitigate the spread of pests and diseases.

Abstract  Apple production has been an important economic activity worldwide. The wide dissemination and cultivation of apple trees in several regions of the world is due to the development of propagation techniques from its domestication to the present time. Apple trees can be propagated by seeds, restricted to the use in breeding programs, and multiplied by several methods of vegetative propagation, both for rootstocks and apple scion cultivars. Considering the high technological level currently used in apple crop management, plant propagation plays a very important role in order to enable seedling production with high morphological quality and free of diseases, requiring new advances and propagation improvements in new releases of rootstocks and apple...

Abstract  Fig tree (Ficus carica L.) stands out due to its range of cultivation and easy adaptation to diverse edaphoclimatic conditions. In addition to its adaptability, fruits have nutraceutical characteristics and are used in industry and for fresh consumption, widely appreciated by the world cuisine. Due to lack of manpower and phytosanitary problems, the area planted in Brazil has decreased recently. To overcome these obstacles, the production of quality seedlings is the first step to obtaining productive and healthy orchards. Therefore, the aim of the present literature review was to gather data referring to advances in research related to the fig tree propagation. Currently, the methods found for fig tree propagation consist of seedling production,...

Abstratct  Brazilian Cherry tree is a native fruit tree belonging to the Myrtaceae family, with ample adaptation to the different edaphoclimatic conditions of Brazil, which makes this fruit widely known. However, there are still few commercial orchards, which may soon be reversed, since studies have shown the benefits of the consumption of this fruit for human health, as well as the potentialities for industrial processing. Thus, Brazilian Cherry tree will no longer be a backyard plant and will be grown in commercial orchards, which demands the production of seedlings with genetic quality. Sexual propagation with the use of seeds should be replaced by asexual propagation by means of cutting, grafting, spreading and tissue culture. The grafting method has...

Abstract  The Myrtaceae family has representatives spread worldwide, and Jabuticaba tree is an important species native to Brazil, which is grown not only in the backyards and domestic orchards, but also in commercial orchards, landscaping projects and in several tropical and subtropical countries. The propagation of this species in a sexual form or by seeds is simple and efficient, being able to reach 100%. However, long juvenile phase and genetic segregation have led to the search for methods that allow the propagation of selected trees and guarantee through their standardized and productive clones, fruit quality and fruiting precocity. Protocols for asexual propagation are still scarce, but they show efficient methods, making possible the commercial use...

Abstract  The lack of an efficient method of propagation in some cultivars makes it difficult to expand the blueberry culture. In Brazil, we still do not produce seedlings with needed quality and quantity to improve the sector. The cloning of the selected material through mini propagation and micro propagation is an alternative to increase the multiplication and rooting capacity of the blueberries. Allied to this, the use of cultivation system without soil for the development of cloned material facilitates the seedlings production. In addition, we can keep matrices in small spaces with the use of mini-gardens and clonal micro-gardens controlling climatic and nutritional factors. In the Laboratory of Fruit Plants Propagation, of the Phytotechnology...

Autores: Schuch,Márcia Wulff; Tomaz,Zeni Fonseca Pinto; Casarin,Josiane Vergara; Moreira,Roseane Maidana; Silva,Jacqueline Barcelos da.
Abstract  In Brazil, there is a growing interest in the crop of the olive tree, especially in those regions considered suitable for cultivation, where low temperatures occur between 8ºC and 10ºC in the period before flowering. The areas with these characteristics are located mainly in the South and Southeast regions of the country, characterized by a temperate climate in function of altitude, with the occurrence of natural vernalization. The propagation is an integral part of the production chain and the first step towards the implantation of the olive tree crop or renovation of the existing orchards. Obtaining quality seedlings, besides guaranteeing uniformity and reliable varietal origin, is a factor that influences the whole life of the orchard,...

Abstract  Papaya (Carica papaya L.) is a fruit tree of great economic and food interest worldwide. Its propagation can occur both sexually and asexually. Traditionally, it is propagated by seeds; however, vegetative propagation has been often used with the use of in vitro and ex vitro culture techniques. In vegetative propagation, the cutting method has been extensively explored. Research has also been developed using grafting. In recent years, papaya cultivation has also become a model for other fruit plants in the use of biotechnological techniques aiming applications ranging from germplasm conservation to genetic transformation of plants. Since the beginning of the 1970s, the culture of papaya tree tissues has been intensely studied, allowing greater...

Advancing our understanding of ocean biogeochemistry, biology, and ecosystems relies on the ability to make observations both in the ocean and at the critical boundaries between the ocean and other earth systems at relevant spatial and temporal scales. After decades of advancement in ocean observing technologies, one of the key remaining challenges is how to cost-effectively make measurements at the increased resolution necessary for illuminating complex system processes and rapidly evolving changes. In recent years, biogeochemical in situ sensors have been emerging that are threefold or more lower in cost than established technologies; the cost reduction for many biological in situ sensors has also been significant, although the absolute costs are still...

Sprat is a pelagic species of increasing commercial interest in European waters, yet little is known about its biology or the drivers of its population fluctuations. As a result, the species is currently without an analytical assessment or forecast across much of the North East Atlantic. The objectives of this study were to: verify otolithbased age estimation of sprat; assess the precision, bias and reproducibility of these age estimates; and, determine the age structure of sprat within one North East Atlantic management unit (Celtic Seas ecoregion). Samples were collected over three years (2011, 2013 &amp; 2014) from both commercial catches and scientific surveys. Counts of daily increments in otoliths were used to establish when the first annulus was...

Agglomeration of wet particles in dense granular flows
Provedor de dados: 5
Autores: Vo, Thanh Trung; Nezamabadi, Saeid; Mutabaruka, Patrick; Delenne, Jean-yves; Izard, Edouard; Pellenq, Roland; Radjai, Farhang.
In order to get insight into the wet agglomeration process, we numerically investigate the growth of a single granule inside a dense flow of an initially homogeneous distribution of wet and dry particles. The simulations are performed by means of the discrete element method and the binding liquid is assumed to be transported by the wet particles, which interact via capillary and viscous force laws. The granule size is found to be an exponential function of time, reflecting the conservation of the amount of liquid and the decrease of the number of available wet particles inside the flow during agglomeration. We analyze this behavior in terms of the accretion and erosion rates of wet particles for a range of different values of material parameters such as...

Aggregation processes of Tuna under Drifting Fish Aggregating Devices (DFADS) assessed through fisher's echosounder buoy in the Indian Ocean
Provedor de dados: 5
Autores: Baidai, Y; Dagorn, Laurent; Amande, Mj; Gaertner, Daniel; Capello, Manuela.
The aggregative behavior of tuna around floating object is widely exploited by the industrial purse-seine fishery, which deploy thousands of floating objects each year in all oceans in order to improve their catches. These fish aggregating devices (FADs) are generally equipped with echosounder buoys that can collect acoustic data, conferring to these devices the status of privileged observation platforms for the fish communities that aggregate. Using a classification model based on supervised learning algorithms trained on M3I buoy data, we were able to translate the acoustic data collected along the trajectories of 5748 drifting FADs newly deployed between 2016 and 2018 in the Indian Ocean into presence or absence of tuna aggregation.

Given the strong effects of behavioural hierarchies on growth in many cultured species and the key role of feed efficiency in aquaculture economics, understanding the nature of the interaction of these variables is important for the sustainability of aquaculture. The relationship between agonistic behaviour, growth and feed efficiency in Nile tilapia, Oreochromis niloticus, was studied by rearing 120 fish in eight aquaria. Fish were video-recorded to estimate the occurrence of agonistic behaviour during a fasting and a refeeding period. Growth, feed intake and feed conversion efficiency (FCE - calculated as the inverse of feed conversion ratio (FCR)) were subsequently measured individually for each fish. Fish showed 58% less agonistic traits during the...

Abstract: The objective of this work was to evaluate the growth and production of a garlic clone subjected to either infection or virus-free conditions, according to bulb and clove size classification. The experiment was carried out in a randomized complete block design with four replicates. Treatments consisted of either virus-infected or virus-free cloves, obtained from bulbs of four size classes and from cloves with three sieve diameters. Vegetative characteristics and plant production were assessed. Plants infected by viral complexes showed a reduction in emergence (8.4%), plant height (9.8%), and production of marketable bulbs (39.4%), as well as a lower average mass of bulbs and cloves. The virus-free clone produced more bulbs in classes 5 (42-47...

ABSTRACT Uneven maturation in canola is an important challenge for its management in regions subject to frost and high rainfall at the end of the cycle. In order to identify practices to maximize grain yield under these growing conditions, this work evaluated the effects of desiccation with herbicides at different phenological stages on Hyola 433, one of the most commonly used hybrids in Brazil. The experiment was conducted in a randomized block design with four repetitions in a 6 x 4 factorial scheme, with five herbicides: paraquat, diquat and ammonium glufosinate at dose of 400 g a.i. ha-1, glyphosate at 1,440 g a.i. ha-1 and saflufenacil at 70 g a.i. ha-1, plus the control, at four phenological stages of silique maturation (G2, G3, G4 and G5)....

ABSTRACT One of the benefits of irrigation with wastewater in agriculture is the reduction in the use of mineral fertilizers and the increase in crop yield. For wastewater application, the use of remote sensing can help to define specific management areas. The aim of this study was to evaluate the yield and the growth of irrigated white oats (Avena sativa L.) with varying treated sewage effluent (TSE) levels. These attributes were then correlated with Normalized Difference Vegetation Index (NDVI) values obtained at four phenological stages of the crop and used to define critical limits of NDVI. The experiment consisted of five TSE treatments differing in irrigation depths (11, 31, 60, 87, and 100%). Mean NDVI values in the crop were determined with an...

Autores: Silva, Gutierres Nelson; Grossi, José Antônio Saraiva; Carvalho, Marcela Silva; Kuki, Kacilda Naomi; Goulart, Samuel de Melo; Pimentel, Leonardo Duarte.
Macauba fruits are oil-rich drupes with high moisture content at harvest. This feature can affect the chemical properties of the oil and increase the costs of biodiesel production. Therefore, it is necessary to adopt postharvest strategies to ensure oil quality. The aim of this work was to evaluate the effect of drying macauba fruit on the quality of the pulp oil. Husked and dehusked fruits were dried at 60°C and then stored. At 0, 15, 45, 100, and 180 days after storage, fruit samples were retrieved, and the oil from the pulp was evaluated for physicochemical parameters. The removal of the husk from the fruits considerably reduced the drying time compared to that of the husked fruits. Drying prevented deterioration of the fruit even after 180 days of...

ABSTRACT:  The white mulberry leaves are typically available on the market in dried or encapsulated form. It was assumed in the study that appropriate drying of leaves of the white mulberry is significant for obtaining intermediate products with high content of compounds having anti-oxidative activity. The purpose of the study was to determine the influence of the temperature of mulberry leaves air drying on the content of phenolic acids and flavonols. It has been determined that the content of these compounds in the leaves depended on the drying temperature. Drying at 60 °C favored release of phenolic acids and flavonols from complexes and/or formation of new compounds. Their total content was 22% higher than in leaves dried at 30 °C. Drying at 90 °C...

Air-sea disequilibrium enhances ocean carbon storage during glacial periods
Provedor de dados: 5
Autores: Khatiwala, S.; Schmittner, A.; Muglia, J.
The prevailing hypothesis for lower atmospheric carbon dioxide (CO2) concentrations during glacial periods is an increased efficiency of the ocean's biological pump. However, tests of this and other hypotheses have been hampered by the difficulty to accurately quantify ocean carbon components. Here, we use an observationally constrained earth system model to precisely quantify these components and the role that different processes play in simulated glacial-interglacial CO2 variations. We find that air-sea disequilibrium greatly amplifies the effects of cooler temperatures and iron fertilization on glacial ocean carbon storage even as the efficiency of the soft-tissue biological pump decreases. These two processes, which have previously been regarded as...

Air-Sea Turbulent Fluxes From a Wave-Following Platform During Six Experiments at Sea
Provedor de dados: 5
Autores: Bourras, Denis; Cambra, Remi; Marié, Louis; Bouin, Marie-noëlle; Baggio, Lucio; Branger, Hubert; Beghoura, Houda; Reverdin, Gilles; Dewitte, Boris; Paulmier, Aurélien; Maes, Christophe; Ardhuin, Fabrice; Pairaud, Ivane; Fraunié, Philippe; Luneau, Christopher; Hauser, Danièle.
Turbulent fluxes at the air‐sea interface are estimated with data collected in 2011 to 2017 with a low‐profile platform during six experiments in four regions. The observations were carried out with moderate winds (2‐10 m s‐1) and averaged wave heights of 1.5 m. Most of the time, there was a swell, with an averaged wave age (the ratio between wave phase speed and wind speed) being equal to 2.8±1.6. Three flux calculation methods are used, namely the eddy‐covariance (EC), the inertial‐dissipation (ID), and the bulk methods. For the EC method, a spectral technique is proposed to correct wind data from platform motion. A mean bias affecting the friction velocity (u*) is then evaluated. The comparison between EC u* and ID u* estimates suggests that a constant...

Ull er et næringsrikt materiale og lavverdiull (skitten, filtet og noen fraksjoner av pigmentert ull)kan ha verdi som en næringsstoffressurs i landbruket. Rapporten omhandler en kartlegging av slik ull gjennom en spørreundersøkelse blant sauebønder i Fosenregionen. Flere gårdbrukere svarte at de kaster eller brenner ullen og noen sa de ønsker seg kunnskap om alternative måter å bruke ullen på. I prosjektet ble ull undersøkt som bestanddel i talle med halm til sau. Tallen ble siden lagt opp i komposter. Etter å ha vært først i talle og deretter i kompost, var ullen på god vei til å brytes ned. Hvorvidt komposten hadde tilfredsstillende spredeegenskaper ble ikke undersøkt i dette forsøket.

ABSTRACT: Allelopathy is defined as the ability of certain plants and microorganisms to interfere with the metabolism of other species through substances released into the environment, being an alternative to control weeds and diseases. In this context, this study aimed to evaluate the allelopathic potential and identify groups of secondary metabolites of Paspalum maritimum Trind. The species Lactuca sativa, Digitaria insularis, Emilia coccinea, and Portulaca oleracea were used as recipient plants. The ethanolic extract was obtained from shoot and root of donor species to evaluate the allelopathic potential. Potentially allelopathic effects were evaluated by means of germination tests, germination speed index, and initial seedling growth. A phytochemical...

ABSTRACT Allometric models defining the relationship between stem diameter and total tree height in the Amazon basin are important because they refine the estimates of tree carbon stocks and flow in the region. This study tests different allometric models to estimate the total tree height from the stem diameter in an ecotone zone between ombrophilous and seasonal forests in the Brazilian state of Roraima, in northern Amazonia. Stem diameter and total height were measured directly in 65 recently fallen trees (live or dead). Linear and nonlinear regressions were tested to represent the D:H relation in this specific ecotone zone. Criteria for model selection were the standard error of the estimate (Syx) and the adjusted coefficient of determination (R²adj),...

Abstract Abstract: The hepatoprotective effects of the ethanolic extracts of propolis (EEP) on alcohol-induced liver steatosis were investigated in Wistar rats. Chronic alcoholic fatty liver was induced by administration of 52% alcohol to male Wistar rats at the dose of 1% body weight for 7 weeks. Then animals were simultaneously treated with 50% ethanol solutions of EEP or normal saline at the dose of 0.1% body weight for 4 further weeks. Serological analyses and liver histopathology studies were performed to investigate the development of steatosis. Microarray analysis was conducted to investigate the alterations of hepatic gene expression profiling. Our results showed that 4-week treatment of EEP helped to restore the levels of various blood indices,...

RESUMO A sarna notoédrica é uma doença altamente pruriginosa, causada pelo ácaro Notoedres cati. O diagnóstico consiste na observação do ácaro no material analisado, sendo o raspado cutâneo o método mais utilizado. Outras técnicas têm surgido como alternativas menos invasivas no diagnóstico de sarnas, sobretudo para demodicose em cães, como a de fita de acetato e o arrancamento de pelos, que vêm se mostrando tão sensíveis quanto o raspado cutâneo no diagnóstico de tal dermatopatia. Desse modo, o objetivo deste estudo foi comparar o raspado cutâneo com dois métodos alternativos para diagnóstico de sarna notoédrica em gatos: fita de acetato e arrancamento de pelo, sendo possível concluir que o método da fita é tão sensível quanto o raspado cutâneo, ambos...

Somatic embryogenesis (SE) is the most striking and prominent example of plant plasticity upon severe stress. Inducing immature carrot seeds perform SE as substitute to germination by auxin treatment can be seen as switch between stress levels associated to morphophysiological plasticity. This experimental system is highly powerful to explore stress response factors that mediate the metabolic switch between cell and tissue identities. Developmental plasticity per se is an emerging trait for in vitro systems and crop improvement. It is supposed to underlie multi-stress tolerance. High plasticity can protect plants throughout life cycles against variable abiotic and biotic conditions. We provide proof of concepts for the existing hypothesis that alternative...

Autores: CASTRO,Vinicius Gomes de; AZAMBUJA,Rafael da Rosa; PARCHEN,Carlos Frederico Alice; IWAKIRI,Setsuo.
ABSTRACT Wood-cement composite (WCC) is a potential construction material for tropical regions, due to its physico-mechanical properties and resistance to decay and fungi attack. However it is important to test alternative production methods and wood materials that are easier and cheaper than those traditionally used, in order to create a higher demand for this product. The aim of this work was to evaluate the use of wood from four Amazonian species (Eschweilera coriaceae, Swartzia recurva, Manilkara amazonica and Pouteria guianensis) in the production of wood-cement composites through a vibro-dynamic compression process, an alternative method to the use of a hydraulic press. The inhibition degree caused by the wood to the cement cure, measured by the...

ABSTRACT Bactrocera carambolae Drew &amp; Hancock is a quarantine pest present in Brazil and is the main phytosanitary barrier for the export of fresh fruits from that country. In this work, we evaluated the effect of Amazonian isolates of Metarhizium on kill larvae, pupae, and adults of B. carambolae in soil applications. The mortality of larvae and pupae in sterile soil treated with Metarhizium anisopliae was 70 %. In addition, 100 % of the adults that emerged from this substrate died up to five days later. This isolate caused the mortality of larvae and pupae in non-sterile soil, but its effect was more evident after adult emergence (70 % mortality up to ten days after emergence). Metarhizium robertsii was effective in killing larvae and pupae of the...

Oral mucositis (OM) is a common and dose-limiting side effect of cancer treatment, including 5-fluorouracil (5-FU) and radiotherapy. The efficacy of the therapeutic measures to prevent OM is limited and disease prevention is not fully observable. Amifostine is a cytoprotective agent with a described anti-inflammatory potential. It is clinically used to reduce radiotherapy and chemotherapy-associated xerostomia. This study investigated the protective effect of amifostine on an experimental model of OM. Hamsters were divided into six groups: saline control group (5 mL/kg), mechanical trauma (scratches) of the right cheek pouch; 5-FU (60 and 40 mg/kg, ip, respectively, administered on days 1 and 2); amifostine (12.5, 25, or 50 mg/kg) + 5-FU + scratches....

ABSTRACT A digestibility assay was conducted in order to determine the digestibility coefficients (DC) of amino acids of feed ingredients in cecectomized adult roosters. In total 48 cecectomized adult roosters were used to assess the coefficient of digestibility of 7 ingredients: corn, soybean meal, soybean concentrate, corn gluten meal, wheat bran, peanut meal, and feather meal. Each ingredient was replicated six times and a group of 6 rooster was used to measure endogenous amino acid losses. After 48 hours of fasting, the roosters were tube fed 20g of ingredients tested twice during a day. At 12 hour-intervals excreta and endogenous losses were collected and immediately freeze-dried for further chemical analysis. At the end of the assay, excreta were...

Provedor de dados: 53
Autores: Mendes,Kassio Ferreira; Alonso,Felipe Gimenes; Mertens,Tatiane Beatriz; Inoue,Miriam; Oliveira,Marcelo Gomes de; Tornisielo,Valdemar Luiz.
ABSTRACT The application of sewage sludge (SS) in agriculture is a practice used worldwide, and it is commonly applied in sugarcane to supply nutrients, with beneficial effects on crop productivity and soil; but SS can increase sorption and decrease desorption of herbicides. However, in tropical soils such as in Brazil, there are no studies regarding the behavior of pre-emergent herbicides, mainly aminocyclopyrachlor and mesotrione, in SS-amended soil. The aim of the present study was to determine the effect of municipal SS applied in agriculture on the sorption–desorption of aminocyclopyrachlor and mesotrione in clay soil. Aminocyclopyrachlor (pyrimidine-2-14C-aminocyclopyrachlor) and mesotrione (cyclohexane-2-14C-mesotrione) sorption–desorption was...

ABSTRACT: A reliable quantification of nitrogen (N) losses by ammonia (NH3) volatilization can contribute to identifying optimized strategies of fertilizer management. The objective of this study was to quantify ammonia volatilization from several organic N sources incorporated into or applied onto the soil surface. Two cultivation areas, under snap bean and corn, were evaluated at Embrapa Agrobiology, Seropédica, Rio de Janeiro (RJ). Both experiments used a randomized complete block design in split-plots, with four replications. The main plots consisted of four organic fertilizers (castor bean cake, bokashi, legume fertilizers, cattle manure), at rates of 200 kg ha-1 N, and a control treatment (without fertilization), and the subplots corresponded to the...

Autores: Megda,Michele Xavier Vieira; Mariano,Eduardo; Leite,José Marcos; Megda,Marcio Mahmoud; Trivelin,Paulo Cesar Ocheuze.
Abstract: The objective of this work was to evaluate the effect of the application of ammonium chloride as a nitrogen source for sugarcane (Saccharum sp.) on the development of the crop’s shoot and roots during two consecutive cycles. The experiment was conducted on a Typic Hapludox in the first and second sugarcane ratoons. The treatments consisted of four N doses (50, 100, 150, and 200 kg ha-1) applied as ammonium chloride (NH4Cl), besides a control, without the application of N. The increase in the NH4Cl dose increased in up to three times soil electrical conductivity in the layer of 0.0-0.2 m, with a consequent increase in the concentration of chlorine in leaves. In the second cycle, the contents of chlorine increased in 1,900 mg kg-1 in the leaf with...

Ammopiptanthus mongolicus stress-responsive NAC gene enhances the tolerance of transgenic Arabidopsis thaliana to drought and cold stresses
Provedor de dados: 74
Autores: Pang,Xinyue; Xue,Min; Ren,Meiyan; Nan,Dina; Wu,Yaqi; Guo,Huiqin.
Abstract Drought and cold are the primary factors limiting plant growth worldwide. The Ammopiptanthus mongolicus NAC11 (AmNAC11) gene encodes a stress-responsive transcription factor. Expression of the AmNAC11 gene was induced by drought, cold and high salinity. The AmNAC11 protein was localized in the nucleus and plays an important role in tolerance to drought, cold and salt stresses. We also found that differential expression of AmNAC11 was induced in the early stages of seed germination and was related to root growth. When the AmNAC11 gene was introduced into Arabidopsis thaliana by an Agrobacterium-mediated method, the transgenic lines expressing AmNAC11 displayed significantly enhanced tolerance to drought and freezing stresses compared to wild-type...

RESUMEN Actualmente, la infección por el virus de dengue (DENV) es uno de los problemas más importantes de salud pública en países tropicales y endémicos como Colombia, pues en tanto puede ser producida por cuatro diferentes serotipos virales, durante las infecciones secundarias se presentan frecuentemente cuadros más severos que incluso pueden llevar a desenlaces fatales. El centro de la fisiopatología del dengue grave es el daño producido al endotelio, que se traduce en un aumento en la permeabilidad vascular que se evidencia como fuga plasmática, descontrol en la coagulación y daño de órganos. Aunque hay varias teorías que explican la enfermedad severa, el fenómeno denominado amplificación de la infección dependiente de anticuerpos (antibody dependent...

An analytical study of the atmospheric boundary layer flow and divergence over a SST front
Provedor de dados: 5
Autores: Ayet, Alex; Redelsperger, Jean-luc.
We present an analytical model reproducing literature‐based numerical simulations of the Marine Atmospheric Boundary Layer (MABL) over a SST front, with wind blowing from the cold to the warm side. Turbulence is parameterised through a varying diffusion coefficient with two critical features: it is parabolic on the vertical and its mean value is decoupled from the MABL height (unlike an Ekman layer model). These two novel features are found essential to recover the internal structure of the MABL from numerical simulations. Different dynamical regimes are obtained and interpreted in terms of non‐dimensional numbers characterising the relative importance of terms driving the momentum equation. A closed‐form expression of the vertically integrated wind...

An Annual Cycle of Submesoscale Vertical Flow and Restratification in the Upper Ocean
Provedor de dados: 5
Autores: Yu, Xiaolong; Naveira Garabato, Alberto C.; Martin, Adrian P; Buckingham, Christian; Brannigan, Liam; Su, Zhan.
Numerical simulations suggest that submesoscale turbulence may transform lateral buoyancy gradients into vertical stratification, and thus restratify the upper ocean via vertical flow. However, the observational evidence for this restratifying process has been lacking due to the difficulty in measuring such ephemeral phenomena, particularly over periods of months to years. This study presents an annual cycle of the vertical velocity and associated restratification estimated from two nested clusters of meso- and submesoscale-resolving moorings, deployed in a typical mid-ocean area of the Northeast Atlantic. Vertical velocities inferred using the non-diffusive density equation are substantially stronger at submesoscales (horizontal scales of 1-10 km) than at...

An assessment of the factors determining rotifer assemblage in river-lake systems: the effects of seasonality and habitat
Provedor de dados: 103
Autores: Serafim-Júnior,Moacyr; Perbiche-Neves,Gilmar; Lansac-Tôha,Fabio A.
ABSTRACT Zooplankton exhibit several trends of variation in space and time, and these trends can be more evident in natural environments without anthropic perturbations. Examples of anthropic factors are climate change, eutrophication and construction of reservoirs. This study evaluated the influence of three factors - seasonality, type of environment and the presence of aquatic macrophytes - on various ecological attributes of rotifers in a river-lake system located in the Paraná River floodplain. Monthly samplings were conducted during 1993 and 1994. The mean species richness per sample was 60 species. The seasonality and the type of environment influenced the ecological attributes of rotifer assemblages, while the presence or absence of aquatic...

Based on the framework of attribute diversity (a generalization of Hill numbers of order q), we develop a class of functional diversity measures sensitive not only to species abundances but also to trait‐based species‐pairwise functional distances. The new method refines and improves on the conventional species‐equivalent approach in three areas: (1) the conventional method often gives similar values (close to unity) to assemblages with contrasting levels of functional diversity; (2) when a distance metric is unbounded, the conventional functional diversity depends on the presence/absence of other assemblages in the study; (3) in partitioning functional gamma diversity into alpha and beta components, the conventional gamma is sometimes less than alpha.

As global change becomes a major concern, the need to contextualize discrete observations to highlight long-term evolutions also becomes more relevant. In response to this challenge, Marine Historical Ecology (MHE) has recently emerged as a new discipline within the marine sciences, dedicated to studying the relationship between long-term evolution of marine ecosystems and temporal variations of external predictors such as meteorological parameters, or descriptors of human activities. In recent years, therefore, considerable effort has been devoted to study long-term time series on fisheries and environmental data. This approach has increased our knowledge about natural variability and functioning of marine environments and has helped us to characterize...

The Mediterranean Sea is now recognized as a hotspot of global change, ranking among the fastest warming ocean regions. In order to project future plausible scenarios of marine biodiversity at the scale of the whole Mediterranean basin, the current challenge is to develop an explicit representation of the multispecies spatial dynamics under the combined influence of fishing pressure and climate change. Notwithstanding the advanced state-of-the-art modeling of food webs in the region, no previous studies have projected the consequences of climate change on marine ecosystems in an integrated way, considering changes in ocean dynamics, in phyto- and zoo-plankton productions, shifts in Mediterranean species distributions and their trophic interactions at the...

Autores: Halouani, Ghassen; Le Loc'H, François; Shin, Yunne-jai; Velez, Laure; Hattab, Tarek; Romdhane, Mohamed Salah; Ben Rais Lasram, Frida.
In order to assist fisheries managers, ecological indicators are needed to evaluate the effects of fishing activities on marine ecosystems and to improve communication of these effects in both public and scientific contexts. Finding appropriate indicators is challenging given the complexity of marine food webs as well as the ecosystem response to fishing pressure. In this study, an end-to-end model developed in the Gulf of Gabes ecosystem (Tunisia) was used to compare the performance of a set of ecosystem indicators in assessing the impact of fishing. This end-to-end model aimed to represent the ecosystem functioning by coupling two existing sub-models, the multispecies individual-based model OSMOSE, representing the dynamics of exploited species and the...

An Estimate of Thorium 234 Partition Coefficients Through Global Inverse Modeling
Provedor de dados: 5
Autores: Le Gland, Guillaume; Aumont, Olivier; Memery, Laurent.
Thorium-234 (Th-234), an insoluble radioisotope scavenged by marine particles, can be used as a proxy of the biological carbon pump. Thorium-234 observations can constrain biogeochemical models, but a necessary first step is to estimate the poorly known partition coefficients between particulate and dissolved phases. In this study, the Th-234 partition coefficients for five particle types, differing in size and chemical composition, are estimated by fitting a global 3-D Th-234 model based on the coupled ocean general circulation-biogeochemistry model NEMO-PISCES (at a resolution of 2 degrees) to a global Th-234 data set (including GEOTRACES data). Surface partition coefficients are estimated between 0.79 and 16.7x10(6). Biogenic silica has the smallest...

Provedor de dados: 83
Autores: Boaventura,Túlio P.; Gil,Viviane S. B.; Gil,Camila S. B.; Peres,Anderson M.; Luz,Ronald K.
ABSTRACT This study tested an external tag for juveniles of Lophiosilurus alexandri and measured the effects of tagging in different size classes of fishes. Experiment 1 evaluated the retention rate and influence of the tag on survival and growth of three hundred fishes divided Small, Medium and Large size classes. After 90 days of experiment the fishes had 100% survival and the tag had a higher retention rate for animals of the Large size class. Experiment 2 evaluated the tag’s influence on hematology parameters of forty-two fishes at 5, 10 and 30 days post-tagging. In this experiment both tagged and untagged animals experienced 9.4% mortality. The hematocrit was higher on the 30th day for tagged animals than for untagged animals. No difference was...

The ocean plays a vital role in the global climate system and biosphere, providing crucial resources for humanity including water, food, energy, and raw materials. There is a compelling need to develop an integrated basin-scale ocean observing system to support of ocean management. We articulate a vision for basin-scale ocean observing – A comprehensive All-Atlantic Ocean Observing Systems that benefits all of us living, working and relying on the ocean. Until now, basin-scale ocean observation has been conducted through loosely-aligned arrangements of national and international efforts. The All-Atlantic Ocean Observing System (AtlantOS) is an integrated concept for a forward-looking framework and basin-scale partnership to establish a comprehensive ocean...

Autores: CARDOSO,YAMILA P.; BRANCOLINI,FLORENCIA; PROTOGINO,LUCILA; PARACAMPO,ARIEL; BOGAN,SERGIO; POSADAS,PAULA; MONTOYA-BURGOS,JUAN I.
Abstract Abstract: Hypostomus commersoni Valenciennes 1836, Hypostomus cordovae (Günther 1880) and Hypostomus laplatae (Eigenmann 1907) have been little studied since their original descriptions. This study shows a comprehensive review of these species from the Lower La Plata Basin, including their taxonomic history, distribution, color patterns, morphology, and ecological and molecular phylogenetic data. Morphological and phylogenetic analyses based on D-loop sequences suggested that H. commersoni can be separated into two subclades, or subgroups. Based on these results and on the non-overlapping distribution range of the two subclades, we conclude that they represent two distinct species, thereby revalidating H. spiniger. The results also suggest that H....

AN INTELLIGENT COMPUTER VISION SYSTEM FOR VEGETABLES AND FRUITS QUALITY INSPECTION USING SOFT COMPUTING TECHNIQUES
Provedor de dados: 111
Autores: G, Narendra V.
The quality of food products is very important for the human health. The large population and the increased requirements of food products makes it difficult to arrive the desired quality. The quality inspection and sorting tons of fruits and vegetables manually is a slow, costly, and an inaccurate process. In this research a vision-based quality inspection and sorting system is developed, to increase the quality of food products. The quality inspection and sorting process depends on capturing the image of the fruits/vegetables, analyzing captured image to discard defected products in order to identify the good or bad. Four different systems for different food products have been developed namely, Orange, Lemon, Sweet Lime, and Tomato. A dataset of 1200...

Provedor de dados: 5
Autores: Sauger, Carine; Quinquis, Jerome; Lepoittevin, Mélanie; Heude-berthelin, Clothilde; Kellner, Kristell; Elie, Nicolas; Dubroca, Laurent.
The European plaice (Pleuronectes platessa) is a commercial species with stock management advice given through the estimation of fish length at maturity (L50) (Mahé et al., 2007). Estimating the maturity of fish species has been worked on by the International Council for the Exploration of the Sea (ICES) that wants to harmonize the definitions, terminologies and practices used to determine the different maturity phases. Project MATO (MATurité Objective des poissons par l’histologie quantitative) will, among other things, bring knowledge on the ovarian histology of the plaice in order to correlate histological maturity with macroscopic parameters like the size color and texture of the ovaries. With this knowledge, the aim of this study is to set up a...

Ocean colour is recognised as an Essential Climate Variable (ECV) by the Global Climate Observing System (GCOS); and spectrally-resolved water-leaving radiances (or remote-sensing reflectances) in the visible domain, and chlorophyll-a concentration are identified as required ECV products. Time series of the products at the global scale and at high spatial resolution, derived from ocean-colour data, are key to studying the dynamics of phytoplankton at seasonal and inter-annual scales; their role in marine biogeochemistry; the global carbon cycle; the modulation of how phytoplankton distribute solar-induced heat in the upper layers of the ocean; and the response of the marine ecosystem to climate variability and change. However, generating a long time series...

An organic cereal row cropping system − A combination of relay undersown cover crop and inter-row hoeing for a balanced Nitrogen and weed management
Provedor de dados: 21
Autores: Phan, Hong TT.
This PhD thesis contains the new findings about a new row cropping system for organic cereal production. The tested row cropping system is feasible for the combination of inter-row hoeing and undersown cover crop for a more balanced N and weed management, which resulted in a yield improvement of the subsequent crop compared to the traditional system including autumn tillage or cover crop. Although the current design with spring inter-row hoeing and undersown cover crop was less effective than autumn tillage for the control of perennial creeping thistle (Cirsium arvense), there was a promising result of the red clover/orchard grass mixture and several possible options to further improve the weed control effect of the new system. Therefore, the new row...

Autores: Melo,F.G.; Godoy,M.E.; Facury Filho,E.J.; Carvalho,A.U.; Meneses,R.M.; Pierezan,F.
ABSTRACT Cases of compressive myelopathy syndrome associated with post vaccinal pyogranulomas were diagnosed post mortem in three cows from a farm in Minas Gerais state, Brazil. These cows presented ataxia and bilateral paresis of the pelvic limbs, which evolved to paralysis, and sternal recumbence. On necropsy, locally extensive areas of the longissimus dorsi muscle were replaced by pyogranulomas supported by moderate amounts of fibrous connective tissue. On the cut surface, some nodules contained yellowish and viscous fluid (purulent exudate) or whitish fluid (interpreted as the oily adjuvant of a vaccine). In the spinal canal of the subjacent vertebrae, compressing the spinal cord, were pyogranulomas identical to those described in the skeletal muscle....

Provedor de dados: 89
Autores: Torres,ACD; Costa,CS; Pinto,PN; Santos,HA; Amarante,AF; Gómez,SYM; Resende,M; Martins,NRS.
ABSTRACT Industrial broilers raised on helminthic medication-free feed were diagnosed with a severe disease caused by Ascaridia galli, characterized by intestinal hemorrhage and obstruction. A. galli was identified based on the morphological features of the nematode. Broilers were raised for a longer period (63 days) for weight recovery, grouped as stunted (n=500), had low body score and had fetid diarrhea. The duodenum-jejunum segment was the most severely affected with obstruction and had localized accumulation of gas. The intestinal mucosa was severely congested with petechial and suffusive hemorrhages. The outbreak resulted in morbidity of about 10% and mortality of up to 4% and was associated to the absence of preventive medication on feed and slack...

Abstract Montane and submontane forest patches in the state of Bahia, Brazil, are among the few large and preserved Atlantic Forests remnants. They are strongholds of an almost complete elevational gradient, which harbor both lowland and highland bird taxa. Despite being considered a biodiversity hotspot, few ornithologists have surveyed these forests, especially along elevational gradients. Here we compile bird records acquired from systematic surveys and random observations carried out since the 1980s in a 7,500 ha private protected area: Serra Bonita private reserve. We recorded 368 species, of which 143 are Atlantic Forest endemic taxa. Some 16 and 13 species are threatened at the global and national levels, respectively. If one accounts for...

We compiled published Brazilian gall-inducing insect inventories aiming to understand trends and biases in this field research and to investigate the factors that potentially explain the diversity of gall-inducing insects among different sampling sites. A total of 51 studies with gall-inducing insect inventories were compiled for Brazil, which sampled 151 sites in 88 municipalities, 13 states and five regions. The number of papers published on gall-inducing insects per year has increased over the last 30 years, being Cecidomyiidae (Diptera) the main galling taxon, Fabaceae the main host-plant family and Protium heptaphyllum (Burseraceae) the most important super-host species in these inventories. We found a great bias in the geographical distribution of...

An Overview on Marek’s Disease Virus Evolution and Evidence for Increased Virulence in Brazil
Provedor de dados: 89
Autores: Torres,ACD; Marin,SY; Costa,CS; Martins,NRS.
ABSTRACT Marek’s disease virus (MDV) has been shown to be evolving to higher virulence. One of the genetic sites involved in virulence which enables such characterization is the 339-amino acid Meq protein encoding gene (meq). The reemergence of clinical Marek’s disease (MD) in vaccinated flocks can be associated to changes in meq. Our studies have shown the presence of very virulent MDV strains in the Brazilian industrial and free-range poultry. We present an overview of MD increasing severity and indicate the necessity of using phylogenetic tools for best accompanying MDV evolution.

Provedor de dados: 56
Autores: Volobueva,A.S.; Orekhov,A.N.; Deykin,A.V.
Animal models of diseases are invaluable tools of modern medicine. More than forty years have passed since the first successful experiments and the spectrum of available models, as well as the list of methods for creating them, have expanded dramatically. The major step forward in creating specific disease models was the development of gene editing techniques, which allowed for targeted modification of the animal's genome. In this review, we discuss the available tools for creating transgenic animal models, such as transgenesis methods, recombinases, and nucleases, including zinc finger nuclease (ZFN), transcription activator-like effector nuclease (TALEN), and CRISPR/Cas9 systems. We then focus specifically on the models of atherosclerosis, especially...

Autores: Oliveira, Luís Flávio Souza de; Staudt, Miriam; Machado, Michel Mansur; Fuentefria, Alexandre Meneghello.
The steroid hormones are lipids in nature, which play crucial roles in several metabolic and behavioral pathways in mammals. Drug therapy uses sterol hormones for treating some disturbances linked with its deficiency; however, the illicit use of these hormones by amateur and elite athletes to enhance performance or body appearance may lead to several health issues. In this study we evaluated the anxious-like behavior and the long-term memory acquisition of male rats undergoing sedentary life-style or physical effort, with or without anabolic-androgenic steroids (ASC) treatment. The results showed a decrease in anxious-like behavioral levels in rats that received ASC treatment associated or not with physical effort, but this treatment did not affect the...

Autores: WORKSHOP SOBRE PRODUÇÃO DE CAPRINOS NA REGIÃO DA MATA ATLÂNTICA, 16., 2019, Coronel Pacheco.
A introdução dos caprinos no País ocorreu com a colonização e permaneceu durante muitos anos sem exploração econômica, dada a influência dos portugueses no incentivo à bovinocultura, para uso como força de trabalho na produção de açúcar no Nordeste. Foi somente na década de 1980, que as primeiras iniciativas de produção comercial foram consolidadas, com destaque para a CCA Laticínios no Sudeste e, na década de 2000, das políticas públicas de aquisição de alimentos, na produção no Nordeste, que se consolidou, especialmente, nos estados do Rio Grande do Norte, Paraíba e Pernambuco. Desde então, a caprinocultura leiteira tem passado por um progressivo processo de transformação de atividade produtora de leite fluído, para outra de alto valor agregado como...

Autores: Menezes Neto, Jayme Bezerra de Menezes; Mattos, Jorge Luiz Schirmer de; Caporal, Francisco Roberto.
O objetivo desta revisão bibliográfica é apresentar um conjunto de ferramentas metodológicas úteis para as análises da dinâmica biofísica de agroecossistemas. Essas metodologias envolvem o cálculo dos Retornos de Energia Investida (REIs), que são indicadores de eficiência energética construídos a partir da quantificação e classificação da Produtividade Primária Líquida (PPL) e do consumo de insumos externos. Esses indicadores expressam não só o custo de energia da biomassa líquida produzida em benefício da sociedade, mas também possibilitam a coleta de informações sobre mudanças estruturais nos agroecossistemas que afetam a manutenção dos serviços ecossistêmicos por eles promovidos. O assunto foi abordado a partir do enfoque teórico-metodológico do...

Chrysodeixis includens (Walker, 1858) (Lepidoptera: Noctuidae) tem sido considerada uma praga severa em lavouras como a soja e o algodão, espécies de grande importância econômica para o Brasil. Inseticidas à base de baculovírus, um grupo de vírus patogênicos a insetos, têm sido usados com sucesso para controlar lepidópteros-praga na agricultura brasileira. A multiplicação em massa do vírus para a produção comercial deve partir da seleção de isolados virais com alta virulência para resultar em um produto com alta efetividade contra a praga no campo. Dois isolados virais, obtidos de lagartas infectadas de Chrysodeixis includens em plantações de soja em Buritis-MG, foram purificados, identificados, analisados e avaliados quanto à atividade biológica por meio...

Para isso, há necessidade de um agente efetivo para a transferência do pólen entre variedades compatíveis. Entre os agentes que atuam na polinização de macieiras as abelhas melíferas se destacam, representando mais de 95% dos polinizadores encontrados sobre as flores. É fato que a abelha Apis mellifera é a espécie mais utilizada nos serviços de polinização dirigida em pomares de maçã no Brasil (Figura 1). Isso deve-se as características de fácil manejo, elevada população de indivíduos nas colmeias, facilidade de transporte dos enxames dos apiários para os pomares e da eficiência da espécie na polinização.

Autores: Gonçalves-Ferri,W.A.; Jauregui,A.; Martins-Celini,F.P.; Sansano,I.; Fabro,A.T.; Sacramento,E.M.F.; Aragon,D.C.; Ochoa,J.M.
Atelectasis and inadequate oxygenation in lung donors is a common problem during the retrieval of these organs. Nevertheless, the use of high positive end-expiratory pressure (PEEP) is not habitual during procedures of lung retrieval. Twenty-one Sprague-Dawley male consanguineous rats were used in the study. The animals were divided into 3 groups according to the level of PEEP used: low (2 cmH2O), moderate (5 cmH2O), and high (10 cmH2O). Animals were ventilated with a tidal volume of 6 mL/kg. Before lung removal, the lungs were inspected for the presence of atelectasis. When atelectasis was detected, alveolar recruitment maneuvers were performed. Blood gasometric analysis was performed immediately. Finally, the lungs were retrieved, weighed, and submitted...

Autores: Santos,Francielle da Rocha; Mariano,Juliana D’Angela; Sestrem Junior,Jonas Abilio; Urbanetz Junior,Jair.
Abstract Sustainability, a concept used to exploit natural resources without harming future generations, is being applied to power generation. In Brazil, the main source of electric energy comes from hydroelectric plants, due to abundant water resources. However, the implementation of these plants causes irreversible impacts on the environment and society. On the other hand, the impacts caused by photovoltaic panels are considerably smaller in the construction phase and zero in the operation phase. This article describes the impacts generated by hydroelectric power plants and gives an overview of the power generated by floating photovoltaic panels using 10% of the area of the reservoirs of the largest hydroelectric power plants in Brazil. The results...

ABSTRACT:  The aim of this study was to use quantile regression (QR) to characterize the effect of the adaptability parameter throughout the distribution of the productivity variable on black bean cultivars launched by different national research institutes (research centers) over the last 50 years. For this purpose, 40 cultivars developed by Brazilian genetic improvement programs between 1959 and 2013 were used. Initially, QR models were adjusted considering three quantiles (τ = 0.2, 0.5 and 0.8). Subsequently, with the confidence intervals, quantile models τ = 0.2 and 0.8 (QR0.2 and QR0.8) showed differences regarding the parameter of adaptability and average productivity. Finally, by grouping the cultivars into one of the two groups defined from QR0.2...

Analysis of the Phenol and Flavonoid Content from Basil Leaves (Ocimum Americanum L) Extract Using Pulsed Electric Field (PEF) Pre-Treatment
Provedor de dados: 111
Autores: Hendrawan, Yusuf; Sabrinauly, Sabrinauly; Hawa, La Choviya; Argo, Bambang Dwi; Rachmawati, Muchnuria.
Basil leaves (Ocimum Americanum Linn) are commonly known to contain phenol and flavonoid compounds which can act as antimicrobial and antioxidants. In general, the bioactive compound can be obtained by conventional extraction method, maceration. To increase the amount of bioactive compounds which can be extracted, it is necessary to conduct pre-treatment using Pulsed Electric Field (PEF). PEF has an advantage in increasing the compound transfer contained in cells to be extracted from the plant tissues via electroporation mechanisms, without causing significant temperature changes. This study aims to determine the effect of electric field strength variations (2, 3, and 4 kV/cm) and duration of pre-treatment (1, 2, and 3 minutes) to total phenol and...

Provedor de dados: 74
Autores: Taxis,Tasia M.; Bauermann,Fernando V.; Ridpath,Julia F.; Casas,Eduardo.
Abstract Acute infections of bovine viral diarrhea virus (BVDV) lead to a range of clinical presentations. Laboratory tests for detection depend on collection of samples during a short viremia. Acutely infected animals remain largely undiagnosed. Transfer RNA halves (tsRNAs) are hypothesized to function like microRNAs to regulate gene expression during an immune response. The objective of this study was to identify tsRNAs in cattle that had been challenged with a non-cytopathic field strain of BVDV. Colostrum-deprived neonatal Holstein calves were either challenged with BVDV (n=5) or mock challenged (n=4). Sera was collected prior to challenge and days 4, 9, and 16 post challenge. RNA was extracted and read counts of small non-coding RNAs were assessed...

Analytical linear modelization of a buckled undulating membrane tidal energy converter
Provedor de dados: 5
Autores: Trasch, Martin; Deporte, Astrid; Delacroix, Sylvain; Germain, Gregory; Drevet, Jean-baptiste.
This paper presents an analytical linear model developed to study the behaviour of a buckled membrane tidal energy converter. The Euler beam theory and the elongated body theory are used for the fluid structure interaction formulation. The effect of electromechanical converters used to convert the undulating motion into electrical energy is reproduced by adding a term equivalent to viscous material damping. The influence of compression force, flaps and hanging conditions is studied, as well as the effects of simulated power take-off through internal damping. The system's behaviour is characterized by undulating mode, critical flow velocity, motion frequency and amplitude. The model shows good agreement in terms of frequency and satisfactory results for the...

Anatomical and histochemical comparison of the primary and adventitious roots of Attalea microcarpa (Arecaceae) at the initial growth stage
Provedor de dados: 36
Autores: CORRÊA,Marcos Melo; ARAÚJO,Maria Gracimar Pacheco de; MENDONÇA,Maria Sílvia de.
ABSTRACT We describe the anatomical structure of roots originating from the apocole of Attalea microcarpa compared to the primary root, by means of usual methods for optical microscopy. The adventitious roots are differentiated in the apocole associated to vascular bundles, and can remain as a single structure or branch. They have the basic root structure characteristic of Arecoideae palms, without schizogenous spaces, which are observed in the primary root, in addition to few air spaces. Mucilages, starch and proteins were present in both types of roots. Adventitious roots of the apocole are described for the first time in Arecaceae.

Provedor de dados: 3
Autores: Pereira, Thiago Scremin Boscolo; Arco, André Del; Hoffmann, Patrícia; Marques, Vanessa Belentani.
Descriptive studies of the fish digestive system are fundamental because they provide information on the biology of the species. Thus, the objective of this study was to morphologically describe the digestive system of the pufferfish, Chilomycterus spinosus spinosus. For this, adult specimens of pufferfish (n = 10) of both sexes were used. The animals were fixed with 10% aqueous formaldehyde solution, dissected, analyzed descriptively and photographed. The results demonstrate that the pufferfish has a morphologically modified digestive system, which is adapted to the defense behavior. This species presents a pouch-shaped diverticulum, that is called abdominal pouch, which allows the expansion of the celomatic cavity and the temporary storage of food....

Autores: Taube, M. J.; Oliveira, L. A.; Vieira, M.; Souza, R. O.; Lehmkuhl, R. C.; Bortolini, Z.
O Nútria, conhecido também como ratão-do-banhado (Myocastor coypus) é um animal silvestre da ordem Rodentia, da família Myocastoridae, e do gênero Myocastor. A família Myocastoridae possui sete gêneros, porém o Myocastor é o único presente no Brasil. Nas espécies silvestres as informações sobre o esqueleto apendicular e ainda descrições anátomoradiográficas são escassas, principalmente em relação aos roedores, tornando difícil a descrição e diagnóstico de afecções que envolvam ossos. O exame radiográfico é um dos métodos mais eficazes na pesquisa de doenças que acometem os animais, devido a sua relação custo-benefício. Desta forma, conhecer a anatomia e a normalidade é fundamental para poder visibilizar as alterações radiográficas. Além de que, a...

ABSTRACT: Anesthetics are effective to reduce or minimize stress in handling operations related to fish cultures. Aiming to avoid residual effects of synthetic drugs, several natural agents, such as essential oils (EOs), have been tested. The aim of this study was to determine the optimal concentration of the EO of Ocimum micranthum for induction of anesthesia in juveniles of silver catfish (Rhamdia quelen) and grass carp (Ctenopharyngodon idella). Results demonstrated that the most suitable concentration to sedate silver catfish and carp is 25μL/L, while to anesthetize 200μL/L is more suitable for silver catfish and 100μL/L for grass carp, because these concentrations induce deep anesthesia in less than three min and recovery in less than five min....

Autores: Oldoni,Lucas V.; Cattani,Carlos E. V.; Mercante,Erivelto; Johann,Jerry A.; Antunes,João F. G.; Almeida,Luiz.
ABSTRACT In the state of Paraná, Brazil, there are no major changes in areas cultivated with annual crops, mainly due to environmental laws that do not allow expansions to new areas. There is a great contribution of the annual crops to the domestic demand of food and economic demand in the exports. Thus, the area and distribution of annual crops are information of great importance. New methodologies, such as data mining, are being tested with the objective of analyzing and improving their potential use for classification of land use and land cover. This study used the classifiers decision tree and random forest with Normalized Difference Vegetation Index (NDVI) temporal metrics on images from Operational Land Imager (OLI)/Landsat-8.

Anomalously deep BSR related to a transient state of the gas hydrate system in the western Black Sea
Provedor de dados: 5
Autores: Ker, Stephan; Thomas, Yannick; Riboulot, Vincent; Sultan, Nabil; Bernard, Céline; Scalabrin, Carla; Ion, G; Marsset, Bruno.
A comprehensive characterization of the gas hydrate system offshore the western Black Sea was performed through an integrated analysis of geophysical data. We detected the Bottom Simulating Reflector (BSR), which marks, in this area, the base of gas hydrate stability. The observed BSR depth does not fit the theoretical steady-state base of gas hydrate stability zone (BGHSZ). We show that the disparity between the BSR and predicted BGHSZ is the result of a transient state of the hydrate system due to the ongoing re-equilibrium since the Last Glacial Maximum. When gas hydrates are brought outside the stability zone due to changes in temperature and sea level, their dissociation generates an increase in interstitial pore pressure. This process is favorable to...

Autores: Santos,Marcelo Guerra; Porto,Gabriela Fraga; Lancellotti,Isabella Rodrigues; Feitosa,Rodrigo M.
Abstract Galls are neoformed plant structures created by cell hyperplasia and hypertrophy induced by a number of organisms, especially insects. After adult insects hatch, senescent galls may remain on the host plant and be occupied by a succession of fauna, the most important and dominant being ants. This study aimed at characterizing the ant fauna successor of stem galls induced by microlepidoptera in Microgramma squamulosa (Kaulf.) de la Sota (Polypodiaceae). Four collections were carried out in the municipality of Nova Friburgo, Rio de Janeiro state, Brazil. The galls were packed in plastic bags and taken to the laboratory. Ants were euthanized and conserved in 70° GL alcohol and later identified. A total of 49 stem galls were collected and analyzed, 15...

This study aimed to assess the ecotoxicological effects of the interaction of fullerene (C60) and benzo[a]pyrene (B[a]P) on the marine mussel, Mytilus galloprovincialis. The uptake of nC60, B[a]P and mixtures of nC60 and B[a]P into tissues was confirmed by GC-MS, LC-HRMS and ICP-MS. Biomarkers of DNA damage as well as proteomics analysis were applied to unravel the toxic effect of B[a]P and C60. Antagonistic responses were observed at the genotoxic and proteomic level. Differentially expressed proteins (DEPs) were only identified in the B[a]P single exposure and the B[a]P mixture exposure groups containing 1 mg/L of C60, the majority of which were down-regulated (~52%). No DEPs were identified at any of the concentrations of nC60 (p &lt; 0.05, 1% FDR)....

Autores: Thomas, Elizabeh R; Allen, Claire S; Etourneau, Johan; King, Amy Cf; Severi, Mirko; Winton, V. Holly L.; Mueller, Juliane; Crosta, Xavier; Peck, Victoria L.
Dramatic changes in sea ice have been observed in both poles in recent decades. However, the observational period for sea ice is short, and the climate models tasked with predicting future change in sea ice struggle to capture the current Antarctic trends. Paleoclimate archives, from marine sedimentary records and coastal Antarctic ice cores, provide a means of understanding sea ice variability and its drivers over decadal to centennial timescales. In this study, we collate published records of Antarctic sea ice over the past 2000 years (2 ka). We evaluate the current proxies and explore the potential of combining marine and ice core records to produce multi-archive reconstructions. Despite identifying 92 sea ice reconstructions, the spatial and temporal...

Abstract Our understanding of the impacts of ongoing global warming on terrestrial species has increased significantly during the last several years, but how climatic change has affected, and will affect, the distribution of earthworms remains largely unknown. We used climate niche modeling to model the current distribution of the giant earthworm Rhinodrilus alatus - an endemic species of the Cerrado Domain in Brazil, which is traditionally harvested and commercialized for fishing bait. R. alatus is sensitive to environmental changes because climate, in synergy with soil attributes, determine its annual reproductive cycle and distribution. The paleoclimatic reconstructions predict important geographical shifts from LGM (~21,000 yBp) to the present...

Abstract This study investigated the effects of the ethanolic extract from the bark of Combretum leprosum (ECL) on intestinal transit and castor-oil induced diarrhea in mice. The oral administration of ECL (750 and 1000 mg/kg) slowed intestinal transit (ID50 of 455 mg/kg). The ECL (250-1000 mg/kg) reduced castor-oil induced diarrhea, in a time- and dose-dependent manner (p &lt; 0.05). To determine if antidiarrheal effect of ECL involves α2-adrenergic or opioid receptor activation, the mice were pretreated with antagonists of these receptors, yohimbine or naloxone respectively. None of these drugs inhibited the antidiarrheal effect of ECL. To test if antidiarrheal effect of ECL is due to an antisecretory action, we realized the enteropooling assay on rats....

Leptospirosis is an important zoonosis spread worldwide. The persistence of the agent in the environment and the high potential of infection are guaranteed, among other factors, by the multiplicity of host species able to harbor and eliminate it. On the other hand, the role of cats in the epidemiology of infection has received little attention.

Abstract Lafoensia pacari A. St. Hill has been used in traditional medicine as an anti-ulcerogenic and anti-inflammatory. Although there is an ethnopharmacological indication for cancer treatment, only a few studies have demonstrated its possible anticancer activity. Thus, the aims of this study were: (1) to evaluate the antineoplastic effect of L. pacari ethanolic extract (LPE) in lung carcinoma cells, (2) to determine the mode of action of LPE and (3) to identify the substances present in LPE. Human and murine lung cancer cell lines were grown in vitro and treated with different concentrations of LPE. Cell cycle and caspase-3 activity assays were performed in order to verify the mode of action. LC-ESI-MS screening was performed to detect the compounds...

ABSTRACT  Background:  The venom of Phoneutria nigriventer spider is a source of numerous bioactive substances, including some toxins active in insects. An example is PnTx4(5-5) that shows a high insecticidal activity and no apparent toxicity to mice, although it inhibited NMDA-evoked currents in rat hippocampal neurons. In this work the analgesic activity of PnTx4(5-5) (renamed Γ-ctenitoxin-Pn1a) was investigated.  Methods:  The antinociceptive activity was evaluated using the paw pressure test in rats, after hyperalgesia induction with intraplantar injection of carrageenan or prostaglandin E2 (PGE2).  Results:  PnTx4(5-5), subcutaneously injected, was able to reduce the hyperalgesia induced by PGE2 in rat paw, demonstrating a systemic effect. PnTx4(5-5)...

Eugenol has been employed for decades as a condiment, an antimycotic, an antibacterial, an antiviral, and an antioxidant, and it is one of the natural analgesics most frequently utilized for pain and inflammation. Our objective was to determine the analgesic/anti-inflammatory effect of eugenol compared with diclofenac, naproxen, and tramadol using the formalin test. The formalin method was used in 6- to 10-week-old Wistar rats (weighing 250 g each) divided into six groups: saline (0.9%); formalin (5%); diclofenac (250 µg/kg); naproxen (400 µg/kg); tramadol (500 µg/kg), and eugenol (1,400 µg/kg), in the intraplantar part of the hind-end trunk of the rats, with n = 5 per group. Eugenol diminished 44.4% of nociceptive behavior in phase 1 and 48% in phase 2 (p...

Anti-predator response of Haliotis tuberculata is modified after only one generation of domestication
Provedor de dados: 5
Autores: Roussel, Sabine; Bisch, T; Lachambre, S; Boudry, Pierre; Gervois, Jl; Lambert, Christophe; Huchette, S; Day, R.
Domestication of Haliotis tuberculata has only recently begun. During the process, we expect that behavioural and physiological traits may evolve to become more adapted to their captive environment. These modifications may result from intentional selection of production traits or unconscious and unintentional selection due to conditions experienced in the farm environment. To study this process at the earliest stage, the progeny of 3 different broodstocks obtained from wild parents, selected farmed abalone and randomly sampled farmed abalone, were studied. After rearing for 16 mo in separate tanks, offspring from the 3 progenies were placed together in sea cages at the same density. After 3 yr, behavioural traits were studied, and the immune status after a...

Abstract Natural products, especially phytochemicals, have been extensively studies and have exhibited important antiproliferative effects. The American native species Urera baccifera (L.) Gaudich. ex Wedd. (Urticaceae) is widely distributed in Brazil, where it is known as urtiga-vermelha or urtigão. The leaves are popularly used as anti-inflammatory, antirheumatic and in the treatment of gastric disorders. However, the antiproliferative potential of this plant against human tumor cells remain to be elucidated. In this study, we evaluated the antiproliferative effects of U. baccifera leaves extracts and fractions against a panel of human tumor cell lines in vitro besides a chemical evaluation of the most active sample by mass spectrometry (ESI-IT-MSn).

Autores: Witten, Stephanie; Ritteser, Carolin; Grashorn, Michael; Aulrich, Karen.
Knowledge of the precaecal (pc) crude protein (CP) and amino acid (AA) digestibility can be used in formulation of poultry diets. The pc CP and AA digestibility can differ between various feedstuffs as well as between batches of the same feedstuff. Thus, table values can provide misleading information. However, they are generally used because there is no standard method to predict the actual pc CP and AA digestibility. Thus, the aim of the study was to evaluate the use of an in vitro multi-enzyme assay to predict the pc digestibility of CP and AA in broiler chicken.  The adapted in vitro multi-enzyme assay provides good estimates for the pc CP and AA digestibility of single feedstuffs for broiler chicken. Further calibrations with in vivo results are...

A disposição de resíduos de processos industriais é um dos grandes desafios das fábricas de celulose e papel. O seu uso como insumo para o plantio florestal é uma forma interessante de disposição, uma vez que resolve o problema legal, ambiental e econômico de destinação, ao mesmo tempo em que contribui para a reposição de nutrientes retirados com a colheita florestal, reciclando nutrientes e mantendo ou melhorando a fertilidade do solo e a sustentabilidade do sítio florestal. Os solos comumente utilizados para os plantios de pinus, como aqueles das classes dos Latossolos, Argissolos, Neossolos Quartzarênicos e Cambissolos são, em sua maioria, ácidos e com baixa disponibilidade de nutrientes e, quando submetidos a amplas extrações de nutrientes pela...

ABSTRACT The apparent faecal digestibility of the essential amino acids from Ω3 PUFA layer diets and feeding solutions to avoid possible adverse effects of such diets were investigated in two experiments conducted on Lohmann Brown laying hens. Experiment 1 used 72 layers assigned to three groups (C1, E1-1, E2), while experiment 2 used 96 layers assigned to four groups (C2, E1-2, E3, E4). All experimental diets have been enriched in Ω 3 PUFA by supplementing a conventional diet (C1, C2) with 5% flaxseed meal and 2% camelina meal. Diets E2 and E4 had an increased level of Cu (150 mg/kg), diets E3 and E4 were supplemented with 0.0125% enzyme mix, while diets E1-1 and E1-2 were only supplemented with 5% flaxseed meal and 2% camelina meal. The digestibility...

ABSTRACT The objective of this study was to evaluate the apparent selectivity of sheep in marandu palisadegrass (Urochloa brizantha cv. Marandu) pastures with four heights at the beginning of the deferment period (15, 25, 35 and 45cm). The deferment period was 92 days and started on 03/21/2014. Evaluations occurred in the beginning (first week), middle (45th day) and end (92nd day) of the grazing period, in winter (06/21/2014 to 09/21/2014). Deferred pastures with 15 and 25cm presented lower forage mass (FM), but higher live leaf (LL) percentage in FM than deferred pastures with 35 and 45cm. The live stem percentage in the FM and the apparent selectivity index (ASI) of the LL were superior in the deferred pasture with 45cm. The dead stem (DS) percentage in...

Autores: Lagos,Maria Jeannine Bonilla; Sobral,Paulo José do Amaral.
ABSTRACT: Edible chitosan-based films, in pure form (CH100), or blended with gelatin (GEL50:CH50), with and without boldo extract (B) were prepared. The oxygen permeability of the films, as well as color changes and antioxidant and antimicrobial activities on beef hamburgers samples were evaluated. CH100+B film exhibited optimal oxygen barrier properties (6.40±0.170cc-mL/[m²-day]), and this value was significantly increased in blended films (GEL50:CH50+B = 12.99±1.50cc-mL/[m²-day]) (P&lt;0.05). All films provoked color changes in hamburger samples during storage, and the samples covered with CH100+B film showed a lower brightness and a higher redness. All films effectively protected beef hamburger from lipid oxidation, and boldo extract incorporation in...

Provedor de dados: 52
Autores: Lombardi,Julia; Ciocia,Felicia; Uniacke-Lowe,Thérèse; Boeris,Valeria; Risso,Patricia; McSweeney,Paul L. H.
Abstract The coagulation of milk by a serin protease from Aspergillus niger NRRL3 was studied by rheology. Cheddar-type cheese was manufactured using 3.5% (v/v) of fungal enzymatic extract and fermentation-produced chymosin was used as control coagulant. Full composition and ripening of both kinds of Cheddar cheese were studied. Differences in the proteolysis of caseins, not only during cheese manufacture but also during ripening, affected cheese composition, texture and peptide profile. Microbial development during ripening was not affected by the coagulant used.

Application of lactic acid bacteria in green  biorefineries
Provedor de dados: 21
Autores: Lübeck, Mette; Lübeck, Peter Stephensen.
Lactic acid bacteria (LAB) have extensive industrial applications as producers of lactic acid, as probiotics, as biocontrol agents and as biopreservatives. LAB play a large role in food fermentation and in silage processes, where crops such as grass, legumes, cereals or corn are fermented into high-moisture feed that is storable and can be used to feed cattle, sheep or other ruminants. LAB also have great applications within green biorefineries, with simultaneous production of protein-rich feed for monogastric animals, silage or feed pellets for ruminants and production of lactic acid or specific amino acids. In green biorefineries, fresh or ensiled wet biomass is mechanically fractionated into green juice and solid residues (press cake), where the plant...

Approche géostatistique de la distribution de poissons plats dans la nourricerie de l'estuaire de Seine
Provedor de dados: 5
Autores: Cariou, Thibault; Dubroca, Laurent; Vogel, Camille; Bez, Nicolas.
L’estuaire de Seine est un habitat essentiel pour les espèces halieutiques emblématiques de la façade Manche-Mer du Nord en sa qualité de nourricerie. Cet estuaire a connu de profondes modifications morphologiques au cours des 30 dernières années des suites d’une forte anthropisation de ces rives. Cet habitat estuarien-côtier, comptant parmi les habitats les plus productifs du milieu marin, joue un rôle central dans le renouvellement des stocks de pêche, en favorisant la croissance et la survie des juvéniles des espèces dites « nourricerie-dépendantes ». Malgré une couverture temporelle très inégale dans les campagnes depuis 30 ans, les suivis des communautés de juvéniles et les observations biotiques (communautés benthiques), abiotiques (hydrodynamisme,...

Eu não canso de me surpreender. Os primeiros telefones celulares, parece mentira, só telefonavam. Os atuais são multifuncionais e, no meu caso, mal consigo me lembrar a última vez que o usei para fazer uma ligação, apesar de tê-lo usado como câmera fotográfica, filmadora, guia de ruas, televisão, régua, alarme, videogame, trena e lanterna entre uma ligação e outra. O que amplifica sobremaneira a usabilidade dos celulares e de outros dispositivos móveis como os tablets, são os aplicativos que podemos baixar nas ?lojas? de aplicativos. Quando precisar de qualquer coisa, seja lá o que for, vale muito a pena conferir se não há um ou mais apps (o apelido de aplicativos que será usado a partir daqui neste texto) que possam o ajudar, pois é bem provável que...

Provedor de dados: 14
Autores: DRUMOND, P. M.; RIBEIRO, M. de F.; KIILL, L. H. P.; SANTOS, R. S.
Apesar dos inúmeros benefícios associados às abelhas-sem-ferrão, algumas espécies são consideradas pragas agrícolas (como as arapuás, por exemplo), por danificarem caules, flores, folhas e/ou frutos, facilitando a entrada de organismos causadores de doenças, prejudicando o desenvolvimento das plantas, bem como reduzindo a quantidade e o valor comercial dos frutos. Esta publicação reúne algumas medidas que podem auxiliar os produtores rurais a minimizar os impactos negativos causados pelas abelhas-arapuás e a conviver com esse grupo de insetos, o qual desempenha importante papel no ecossistema.

Autores: LIMA FILHO, R. de; REIS, F.; PEDREIRA, B. C. e; MARCHIÓ, W.
Os desafios da pecuária remetem a dois mundos: resultados técnicos e econômicos. Saber conduzir a atividade agropecuária de maneira a obter sempre esses dois sucessos é o que tem atraído os produtores para a utilização de tecnologias de intensificação sustentável. Dentre elas, a integração de sistemas tem se tornado uma prática cada vez mais comum. Os sistemas integrados de produção agropecuária podem gerar de 2 a 3 vezes mais rentabilidade que sistemas convencionais, entregando resultados entre R$ 2.500,00 e R$ 7.000,00 por hectare líquido com a adoção da integração, e é exatamente sobre esse sistema que o artigo aborda.

Provedor de dados: 74
Autores: Brandão,José Henrique S. G.; Rodrigues,Nureyev F.; Eguiluz,Maria; Guzman,Frank; Margis,Rogerio.
Abstract Araucaria angustifolia is endemic to southern Brazil. Known as Brazilian pine, A. angustifolia is the only native conifer species with economic and social relevance in this country. Due to massive exploitation, it has suffered a significant population decline and currently is classified as critically endangered. This encouraged the scientific community to investigate genetic features in Brazilian pine to increase resources for management and preservation. In this work, RNA-Seq data was used to determine the complete nucleotide sequence of the A. angustifolia chloroplast genome (cpDNA). The cpDNA is 146,203 bp in length and contains 122 genes, including 80 protein-coding genes, 5 ribosomal RNA genes, and 37 tRNA genes. Coding regions comprise...

Provedor de dados: 39
Autores: Duarte,Lorrane Marques; Bertini,Simone Cristina Braga; Stürmer,Sidney Luiz; Lambais,Marcio Rodrigues; Azevedo,Lucas Carvalho Basilio.
ABSTRACT Arbuscular mycorrhizal fungi (AMF) play an important role in plant community productivity and structure, and so studying the factors that affect the diversity and structure of this fungal community is important for understanding their ecology in tropical forests. We investigated AMF spore communities and root colonization under three forest phytophysiognomies (Restinga Forest, REF; Lowland Ombrophilous Dense Forest, LLF; and Montane Ombrophilous Dense Forest, MTF). Spore abundance was lowest in LLF and highest in REF, with no statistical differences relative to MTF. Spore diversity indices and root colonization rates were not statistically different among the phytophysiognomies. However, principal components analysis revealed that AMF community...

ABSTRACT The inoculation of arbuscular mycorrhizal fungi (AMF), increasing the rhizospheric influence, might provide higher levels of bioactive compounds. Thus, the objective was to evaluate the influence of the AMF inoculation on the physicochemical components of fruit’s quality in field. Strawberry fruits from cultivars Camarosa, Aromas, Camino Real, Monterey, Portola, San Andreas and Albion in 2016, and Camarosa, Camino Real, Monterey and Albion in 2017 were either inoculated or non-inoculated with AMF. The analyzed physicochemical components of fruit’s quality were ascorbic acid, titrated acidity, pH, soluble solids, soluble solids/titrated acidity ratio, phenolic compounds, anthocyanins, and firmness. The inoculation with AMF on strawberry plants in...

ABSTRACT The plant Varronia leucocephala is widely used in Brazil for its therapeutic properties. However, a major problem for the seedlings is the low percentage of root formation. The objective of this study was to establish a rooting protocol for V. leucocephala cuttings, using phytoregulators and microelements associated with arbuscular mycorrhizal fungi. The auxin indole-3-butyric acid (IBA) concentration of 1500 mg L-1 showed the best rooting percentage, and it is proposed associating the microelements zinc and boron with the highest IBA doses. Although an increase in the rooting percentage was observed in the presence of zinc, it was not the most suitable for improving the percentage of propagation. Consequently, association of arbuscular...

Autores: Fonseca,Arley José; Freitas,Ana Flávia de; Carvalho,Gladyston Rodrigues; Carneiro,Marco Aurélio Carbone; Vilela,Diego Júnior Martins; Fassio,Larissa de Oliveira.
ABSTRACT The benefits of mycorrhization occur with the growth of hyphae in colonized roots by promoting an increase of the contact surface which improves the initial growth due to a better absorption of water and nutrients. The objective was to evaluate the effect of arbuscular mycorrhizal fungus Rhizophagus clarus inoculation over the initial development and nutritional response of six genotypes of Coffea arabica L. Six genotypes of Coffea arabica L. were used (MGS Aranas, H29-1-8-5, Red Catuai IAC 144, IPR 100, Catigua MG2, Paraíso H 419-1) and with arbuscular mycorrhizal fungus - AMF: Rhizophagus clarus and without the application of the fungus. For the production of coffee seedlings, seeds were placed to germinate in plastic trays with sterile sand....

Multi‐model Arctic Ocean ``Climate Response Function” (CRF) experiments are analyzed in order to explore the effects of anomalous wind forcing over the Greenland Sea (GS) on poleward ocean heat transport, Atlantic Water (AW) pathways, and the extent of Arctic sea ice. Particular emphasis is placed on the sensitivity of the AW circulation to anomalously strong or weak GS winds in relation to natural variability, the latter manifested as part of the North Atlantic Oscillation (NAO). We find that anomalously strong (weak) GS wind forcing, comparable in strength to a strong positive (negative) NAO index, results in an intensification (weakening) of the poleward AW flow, extending from south of the North Atlantic Subpolar Gyre, through the Nordic Seas, and all...

Santarém and Belém were the municipalities with the highest number of species records, with 139 and 88, respectively. The high number of Ctenuchina records in the Amazon is underestimated because this subtribe has never been sampled in the vast majority of the biome. This is a worrying scenario because the Amazon has the world highest absolute rate of forest reduction. To suggest...

The objective of this study was to verify the agreement between pre-programmed and executed pacing during race walking and whether level of the athletes experience and performance influenced this relationship. Twenty-nine national and international race walkers participated in this study (14 males, 24.0±7.1 years old, and 15 females, 23.3±7.3 years old). Pre-programmed pacing for 10- and 20-km official walking races was self-selected via demonstrative pacing charts prior to races, while executed pacing was analyzed by a specialist investigator via an individual plot of current velocity versus distance. There was no agreement between pre-programmed and executed pacing (P=0.674). There was no association between the ability to match the pre-programmed pace...

Polymetallic seafloor massive sulphide deposits are potential targets for deep-sea mining, but high concentrations of metals (including copper - Cu) may be released during exploitation activities, potentially inducing harmful impact. To determine whether shallow-water shrimp are suitable ecotoxicological proxies for deep-sea hydrothermal vent shrimp the effects of waterborne Cu exposure (3 and 10 days at 0.4 and 4 μM concentrations) in Palaemon elegans, Palaemon serratus, and Palaemon varians were compared with Mirocaris fortunata. Accumulation of Cu and a set of biomarkers were analysed. Results show different responses among congeneric species indicating that it is not appropriate to use shallow-water shrimps as ecotoxicological proxies for deep-water...

Are we close to knowing the plant diversity of the Amazon?
Provedor de dados: 42
Autores: HOPKINS,MICHAEL J.G.
Abstract: Amazonia is often cited as having the most diverse flora on the planet. However, the total number of species of higher plants in the region has been largely a matter of guesswork. Some recent publications have estimated the total number of species present, which indicate a lower overall diversity than was estimated in the past. However, analysis of the sampling density across the region, and data from various sources suggest that there may be reason why the recent figures may be considerable underestimates. I believe that much more investment in extensive collecting of quality plant specimens is needed to encounter the very large number of rare and local species that might never have been collected. Unfortunately the tendencies of investment in...

Provedor de dados: 52
Autores: Sánchez-Gendriz,Ignacio; Hernández-Seoane,D.; Sóñora-Mengana,A.; Pascau-Simón,A.
Abstract Venous refilling time (VRT) can diagnose the presence of venous diseases in lower limbs. In order to calculate VRT it is necessary to determine the End of the Emptying Maneuvers (EEM). First Derivative Method (FDM) can be employed for automatic detection of the EEM, but its sensitivity to artifacts and noise can degrade its performance. In contrast, studies report that Area Triangulation Method (ATM) evinces effectiveness in biosignals point finding. This work compares the exactness of ATM and FDM for recognition of the EEM. The annotations made by 3 trained human observers on 37 photoplethysmography records were used as a reference. Bland-Altman graphics supported the analysis of agreement among human observers and methods, which was complemented...

Argo DAC profile cookbook
Provedor de dados: 5
Autores: Scanderbeg, Megan; Rannou, Jean-philippe; Wong, Annie; Klein, Birgit; Schmid, Claudia; King, Brian; Van Wijk, Esmee.
This DAC cookbook is to include instructions for the DACs on how to calculate different variables for the Argo profile files. This is especially true for some of the additional sensors that are being added to Argo floats. The extra variables increase the complexity of the profile file and extra instructions may be necessary, depending on float and sensor type. It is separate from other data manuals because users do not need to understand all these details, but that it is important that all DACs to be calculating the variables in the same manner. There are instructions in this cookbook that apply to all floats and some that apply to only certain float types. Look through the table of contents for the specific float types included.

RESUMEN En los mares tropicales hay fondos duros sumergidos que albergan corales pero que no son de origen coralino. Este es el caso del sector del Banco de las Ánimas, en la plataforma continental del golfo de Salamanca, mar Caribe colombiano. En su parte superior (14-16 m de profundidad) hay montículos bajos de bloques y lajas de arenisca, a manera de arrecifes, colonizados por biota coralina y corales dispersos. Para confirmar su fitología, se realizó un primer análisis petrográfico, que mostró que las rocas están conformadas por arenas de grano muy fino, maduras en textura, cementadas por dolomita. Se propone que estos arrecifes fueron formados en un sistema playa-duna-laguna de un antiguo nivel del mar, similar a la actual barra costera de Salamanca....

The dense AlpArray network allows studying seismic wave propagation with high spatial resolution. Here we introduce an array approach to measure arrival angles of teleseismic Rayleigh waves. The approach combines the advantages of phase correlation as in the two-station method with array beamforming to obtain the phase-velocity vector. 20 earthquakes from the first two years of the AlpArray project are selected, and spatial patterns of arrival-angle deviations across the AlpArray are shown in maps, depending on period and earthquake location. The cause of these intriguing spatial patterns is discussed. A simple wave-propagation modelling example using an isolated anomaly and a Gaussian beam solution suggests that much of the complexity can be explained as...

Abstract: The objective of this work was to compare methods of obtaining the site index for eucalyptus (Eucalyptus spp.) stands, as well as to evaluate their impact on the stability of this index in databases with and without outliers. Three methods were tested, using linear regression, quantile regression, and artificial neural network. Twenty-two permanent plots from a continuous forest inventory were used, measured in trees with ages from 23 to 83 months. The outliers were identified using a boxplot graphic. The artificial neural network showed better results than the linear and quantile regressions, both for dominant height and site index estimates. The stability obtained for the site index classification by the artificial neural network was also...

ABSTRACT Onion is the third most consumed vegetable worldwide, such as potatoes and tomatoes. Its conservation is influenced by temperature and humidity, and greatest losses occur at postharvest due to lack of storage infrastructure. Thus, the aim of this study was to evaluate the effect of partial cooling in vertical silo on postharvest conservation of cured onion bulbs cultivar Bola Precoce. The experimental design was completely randomized, with six replicates, arranged in split plot scheme. Plots consisted of two storage conditions: onion bulbs stored in silo 1 at room temperature (T1) and bulbs stored in silo 2 with artificial cooling (T2). Subplots were two periods of bulb removal from storage (0 and 14 days). We evaluated peel color, using chroma...

Autores: OLIVEIRA, A. R. de; ARRIEL, N. H. C.
Neste capítulo, foram apresentadas diversas cultivares recomendadas para as regiões dependentes de chuva. Contudo, a tolerância de cada uma é variável, uma vez que o Semiárido brasileiro apresenta subdivisões em relação ao clima, notadamente, em relação aos índices pluviométricos. Portanto, a importância da busca de informações específicas sobre cada cultivar é essencial para o sucesso da cultura. Mesmo assim, o que se pode dizer, de modo geral, é que o plantio deve sempre ser orientado para que ocorra no período chuvoso, a fim de que a cultura tenha maior potencial de expressar sua produtividade.

Autores: ALVES, S. A. M.
A Mancha Foliar de Glomerella é uma doença que afeta a macieira durante o período de verão, principalmente os clones da cultivar Gala. Uma vez constatada a doença no pomar é de difícil controle devido a velocidade de desenvolvimento e a baixa eficiência dos fungicidas em atuar como curativos. Ademais, a planta pode comportar-se como extremamente suscetível e perder as folhas. A seguir são apresentadas as principais características dessa doença.

Autores: MOURA, M. S. B. de; ESPÍNOLA SOBRINHO, J.; SILVA, T. G. F. da; SOUZA, W. M. de.
O Semiárido brasileiro é caracterizado por um conjunto de períodos com balanços hídricos negativos, resultantes da precipitação média anual inferior a 800 mm, insolação média de 2.800 horas por ano e umidade relativa anual média em torno de 50% (MOURA et al., 2007). Neste ambiente, onde o clima é uma das principais características, a ocorrência de secas e a precipitação concentrada em quatro meses do ano são determinantes para a sobrevivência das famílias, da produção agrícola e dos rebanhos. Dessa forma, este capítulo aborda os principais sistemas meteorológicos que ocasionam as precipitações no Semiárido brasileiro e traz um resumo dos mapas climáticos de chuva, evaporação, temperatura e umidade relativa do ar desse ambiente único no Brasil.

ABSTRACT Lygophis flavifrenatus Cope, 1862 is a terrestrial dispsadid distributed in subtropical Brazil, Paraguay, Uruguay, and Argentina. Herein, we present data on sexual dimorphism and reproductive biology of this very poorly studied species. A total of 108 specimens (55 females, 50 males, three hatchlings with unidentified sex) from Brazilian states of Rio Grande do Sul, Santa Catarina and Mato Grosso do Sul were analyzed. Sexual dimorphism by size, body dimensions (tail length, head length, head width) and a number of ventral and subcaudal scales is not well marked in the species. Mature females attain the greater size and have a higher number of ventral scales than mature males. Mature males, in turn, presented longer tail, longer and wider head and...

Abstract We studied aspects of the reproductive behaviour and development of two species of Sarcophagidae (Diptera) of potential forensic importance, Blaesoxipha stallengi (Lahille, 1907) and Sarcophaga ruficornis (Fabricius, 1794), which are dominant in assemblages in dry forests in Northeastern Brazil. We described the behavioural acts associated with courtship and mating and estimated the development time (from egg/larva until adult) - of both species. Description of the reproductive behaviour was based on 50 couples of each species whereas 250 larvae were used for the estimation of the developmental time. A total of 55 successful copula were observed for B. stallengi and 142 for S. ruficornis. Pre-copulatory behaviour differed between the species, as...

Consequences of exposure to polyaromatic hydrocarbons (PAH), toxic components of crude oil, on fish has been widely documented due to their ecological and economical importance. However, although forming a valuable and consistent body of knowledge, use of these data in spill response is limited. Objective of the present study was thus to facilitate the translation of published data into information of operational value. For this, we investigated the dose‐response relationship between dispersant‐treated oil exposure and ecologically‐relevant consequences by combining laboratory and field experiments. Effects were examined over almost a year using juveniles of the slow growing, commercially important European sea bass (Dicentrarchus labrax). Moreover, a...

Assessing the spatial origin of Meltwater Pulse 1A using oxygen‐isotope fingerprinting
Provedor de dados: 5
Autores: Yeung, N.k.h.; Menviel, L.; Meissner, K.j.; Sikes, E.
One of the major phases of sea level rise during the last deglaciation (~19‐11 thousand years before present (ka BP)) is Meltwater Pulse‐1A (MWP‐1A, ~14.5 ka BP), when sea levels rose by 8.6 to 18 meters in less than 400 years. Whether the meltwater originated from the partial disintegration of northern hemispheric (NH) ice sheets, from Antarctica, or both, remains controversial. Here we perform a series of idealized transient simulations of the last deglaciation, focusing on MWP‐1A, with a three‐dimensional oxygen‐isotope enabled Earth System Climate Model. Three meltwater scenarios are considered during MWP‐1A: a sole northern hemispheric source discharging into the North Atlantic, a sole Antarctic source and a combined NH‐Antarctic source. A comparison...

Describing how communities change over space and time is crucial to better understand and predict the functioning of ecosystems. We propose a new methodological framework, based on network theory and modularity concept, to determine which type of mechanisms (i.e. deterministic versus stochastic processes) has the strongest influence on structuring communities. This framework is based on the computation and comparison of two networks: the co-occurrence (based on species abundances) and the functional networks (based on the species traits values). In this way we can assess whether the species belonging to a given functional group also belong to the same co-occurrence group. We adapted the Dg index of Gauzens et al. (2015) to analyze congruence between both...

Abstract  Background: Studies on toad poison are relevant since they are considered a good source of toxins that act on different biological systems. Among the molecules found in the toad poison, it can be highlighted the cardiotonic heterosides, which have a known mechanism that inhibit Na+/K+-ATPase enzyme. However, these poisons have many other molecules that may have important biological actions. Therefore, this work evaluated the action of the low molecular weight components from Rhinella schneideri toad poison on Na+/K+-ATPase and their anticonvulsive and / or neurotoxic effects, in order to detect molecules with actions of biotechnological interest.  Methods: Rhinella schneideri toad (male and female) poison was collected by pressuring their...

ABSTRACT The Atlantic Forest of southeastern Brazil has been considered to have the highest number of tree species per hectare in the world. Assessing the influence of climate on tropical tree species is a priority in the face of ongoing climate change, and for which dendrochronological studies have been important. We address the dendrochronological potential of Licaria bahiana Kurz (Lauraceae), an endemic species of the Atlantic forests. We studied growth ring anatomy of L. bahiana and applied dendrochronological methods to investigate how short-term variation in climate affect its radial growth. Distinct growth rings were observed in all individuals and demarcated by darker tangential fiber zones in latewood. Trees showed high climatic sensitivity (0.48)...

Provedor de dados: 111
Autores: Shiraj-Um-Monira, Syeeda.
This study was conducted to observe the effect of formalin application on the post-harvest quality and shelf life of mango. Mango samples were treated with different concentrations of formalin solutions (10, 100 and 1000 ppm) in two different modes (dipping and spraying) and stored for seven days at ambient condition. Physical characteristics, such as weight loss, color, texture and shrinkage and residual formalin content were observed at every alternate day during storage period. Formalin treatment (dipping and spraying) did not bring up any positive effect in increasing the shelf life of mango. Rather treated with higher concentration of formalin solution (10 ppm&lt;100 ppm&lt;1000 ppm) caused internal and external deterioration. Residual formalin...

Autores: minteh, mustapha.
Abstract: Maintenance cost of agricultural machines accounts for about 10 to 15% of total production cost and this tends to increase as the machine gets older. To stabilized this already high cost, agricultural machinery maintenance engineers chose Preventive Maintenance (PM) strategy. However, the latter may not produce the desired results especially when machines are used under different operating context. In this paper, an assessment of the effects of PM strategy on reliability indicators (failure rate, mean time between failures (MTBF), mean time to repair (MTTR) and mechanical availability) of a rice combine harvester Mitsubishi TVR96 working under the operating context of Pacharr rice fields in The Gambia, is discussed. These reliability indicators...

Assessment of the metal contamination evolution in the Loire estuary using Cu and Zn stable isotopes and geochemical data in sediments
Provedor de dados: 5
Autores: Ferreira Araujo, Daniel; Ponzevera, Emmanuel; Briant, Nicolas; Knoery, Joel; Sireau, Teddy; Mojtahid, Meryem; Metzger, Edouard; Brach-papa, Christophe.
In this work, a multi-elemental approach combining Cu and Zn stable isotopes is used to assess the metal contamination evolution in the Loire estuary bulk sediments. Elemental geochemical data indicate an increase of metal concentrations from the beginning of the industrial period peaking in the 1990s, followed by an attenuation of metal contamination inputs to the estuary. Zinc isotope compositions suggest a binary mixing process between Zn derived from terrigenous material and multi-urban anthropogenic sources. Copper isotope systematics indicate a single natural dominant source represented by weathered silicate particles from soils and rocks. This work demonstrates the applicability of Zn isotopes to identify anthropogenic Zn sources in coastal systems,...

Autores: Garcia,Maria I.; Murúa,Albérico F.; Díaz-Nieto,Leonardo M.; Acosta,Juan C.; Rios,Claudia de Los; Cano,Florencia A.; Blanco,Graciela M.
ABSTRACT Larvivorous fish have been studied as potential biocontrol agents of mosquito larvae and pupae through their trophic interactions. The use of native ﬁsh for mosquito control may have beneﬁts for both aquatic biodiversity and human health. Evaluating the effect of vegetation on the predatory efficacy is fundamental to determine if this species can be used as a biocontrol agent. With the aim of evaluating Jenynsia multidentata (Jenyns, 1842) as a biocontrol agent of Culex pipiens Linnaeus, 1758, we tested its predatory capacity in the presence or absence of aquatic vegetation under laboratory conditions. Two independent experiments were conducted. Larval consumption at a density of 60 larvae (6 larvae/l) was significantly reduced with the vegetation...

Abstract Despite rapid advances in both the early detection and treatment of cancer, the mortality from this disease remains high, which justifies the development of new products that are more selective and effective and have fewer side effects. Accordingly, a novel ester was synthesized that contains two pharmacophores with important biological activities: (I) 4-aminoantipyrine, which has anti-inflammatory and antioxidant effects, and (II) the pharmacophore 1,4-dioxo-butenyl, which has cytotoxic activity. When administered alone, this compound is non-genotoxic, and it does not cause an increasing in splenic phagocytosis. Nevertheless, it can induce cell death. When administered in combination with commercial chemotherapeutic agents, such as doxorubicin,...

ABSTRACT In the Brazilian Cerrado biome, there are wetlands locally known as “Veredas”, which are swampy plains between hills and rivers. Since the 1970’s, the Cerrado biome has been gradually converted to livestock, crop, or forestry production. Until now, very few studies were conducted to evaluate the baseline contents of trace elements in Cerrado wetland soils. Due to their position in the landscape (bottom lands), the wetlands are potentially susceptible to contamination by runoff and/or leaching from surrounding areas at higher altitudes. This work evaluated the As, Cd, Pb, Ni, Zn, Cu, Mn, and Fe contents in soils from six wetlands (undisturbed and disturbed) in the Minas Gerais Triangle region, Brazil. In each wetland, we collected topsoil samples...

Brain-derived neurotrophic factor (BDNF) is widely expressed in the central nervous system and prolongs the survival of dopaminergic neurons in the substantia nigra. Several studies have recently investigated the association between BDNF G196A (Val66Met), a single nucleotide polymorphism influencing cognitive processes, and cognitive impairment in Parkinson's disease (PD), but with contradictory findings. Thus, this meta-analysis was performed to clarify the possible association. Relevant studies were identified by a systematic search of PubMed, Embase, and China National Knowledge Infrastructure (CNKI) databases. The strength of the association was evaluated using crude odds ratios and 95% confidence interval. Finally, six studies involving 532 cases and...

ABSTRACT: Despite important biotic stresses to common bean, Anthracnose (ANT) and Angular Leaf Spot (ALS) can cause losses of up to 80 % and occur in more than 60 countries around the world. Genetic resistance is the most sustainable strategy to manage these diseases. Thus, we aimed to (1) identify new SNP markers associated with ALS and ANT resistance loci in elite common bean lines, and (2) provide a functional characterization of the DNA sequences containing the identified SNP markers. We evaluated 60 inbred lines, under field conditions, which represent the elite germplasm developed by the Embrapa common bean breeding program across 22 years, in terms of severity of the ALS and ANT. The lines were genotyped with 5,398 SNPs. Then, a Mixed Linear Model...

ABSTRACT:  The aim of the present study was to explore the association between milk protein content and casein micelle size and to examine the effects of casein micelle size on enzymatic curd strength and dry matter curd yield using reduced laboratory-scale cheese production. In this research, 140 bulk tank milk samples were collected at dairy farms. The traits were analyzed using two linear models, including only fixed effects. Smaller micelles were associated with higher κ-casein and lower αs-casein contents. The casein micellar size (in the absence of the αs-casein and κ-casein effects) did not affect the enzymatic curd strength; however, smaller casein micelles combined with higher fat, lactose, casein and κ-casein contents exhibited a favorable effect...

Abstract Copy number alterations (CNAs) are a frequent feature in human breast cancer, and one of the hallmarks of genomic instability. The FOSL1, GSTP1 and CCND1 genes are located at 11q13, a cytoband commonly affected by CNA in breast cancer, with relevant function in progression and invasion. Our main goal was to analyze CNAs of these genes and determine their association with breast cancer subtypes. Seventy-three cases of invasive breast tumors [52 Luminal, 7 HER2+ and 14 triple negative (TNBC) subtypes] were analyzed by TaqMan assays. CNAs were observed for all genes, with gains more frequently observed. Gains of the FOSL1 gene were observed in 71% of the cases. This gene was the only one with a statistically significant difference (p&lt;0.001) among...

Abstract Long non-coding RNAs (lncRNAs) are implicated in various cellular and pathological processes. Two lncRNAs, myocardial infarction-associated transcript (MIAT) and metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), may be involved in the pathogenesis of coronary artery disease (CAD). Here, we aimed to determine the relative circulating levels of MIAT and MALAT1 in 110 stable CAD patients and 117 controls and to correlate their levels with the clinical and laboratory data. Peripheral blood expression levels were quantified by Real-Time qPCR. The median MIAT expression level in CAD patients was significantly 12-fold higher than controls (p&lt;0.001). Otherwise, the median MALAT1 expression level was comparable in patient and control...

The Atlantic Meridional Overturning Circulation (AMOC) extends from the Southern Ocean to the northern North Atlantic, transporting heat northwards throughout the South and North Atlantic, and sinking carbon and nutrients into the deep ocean. Climate models indicate that changes to the AMOC both herald and drive climate shifts. Intensive trans-basin AMOC observational systems have been put in place to continuously monitor meridional volume transport variability, and in some cases, heat, freshwater and carbon transport. These observational programs have been used to diagnose the magnitude and origins of transport variability, and to investigate impacts of variability on essential climate variables such as sea surface temperature, ocean heat content and...

Atlantic Multidecadal Oscillations drive the basin-scale distribution of Atlantic bluefin tuna
Provedor de dados: 5
Autores: Faillettaz, Robin; Beaugrand, Gregory; Goberville, Eric; Kirby, Richard R.
The Atlantic bluefin tuna (hereafter referred to as "bluefin tuna"), one of the world's most valuable and exploited fish species, has been declining in abundance throughout the Atlantic from the 1960s until the mid-2000s. Following the establishment of drastic management measures, the stock has started to recover recently and, as a result, stakeholders have raised catch quotas by 50% for the period 2017-2020. However, stock assessments still omit the natural, long-term variability in the species distribution. Here, we explore the century-scale fluctuations in bluefin tuna abundance and distribution to demonstrate a prevailing influence of the Atlantic Multidecadal Oscillation (AMO) to provide new insights into both the collapse of the Nordic bluefin tuna...

Atmosphere‐Ocean CO2 Exchange Across the Last Deglaciation from the Boron Isotope Proxy
Provedor de dados: 5
Autores: Shao, Jun; Stott, Lowell D.; Gray, William R.; Greenop, Rosanna; Pecher, Ingo; Neil, Helen L.; Coffin, Richard B.; Davy, Bryan; Rae, James W.b.
Identifying processes within the Earth System that have modulated atmospheric pCO2 during each glacial cycle of the late Pleistocene stands as one of the grand challenges in climate science. The growing array of surface ocean pH estimates from the boron isotope proxy across the last glacial termination may reveal regions of the ocean that influenced the timing and magnitude of pCO2 rise. Here we present two new boron isotope records from the subtropical‐subpolar transition zone of the Southwest Pacific that span the last 20 kyr, as well as new radiocarbon data from the same cores. The new data suggest this region was a source of carbon to the atmosphere rather than a moderate sink as it is today. Significantly higher outgassing is observed between ~16.5‐14...

Autores: Menzel Barraqueta, Jan-lukas; Klar, Jessica K.; Gledhill, Martha; Schlosser, Christian; Shelley, Rachel; Planquette, Helene; Wenzel, Bernhard; Sarthou, Geraldine; Achterberg, Eric P.
Atmospheric deposition is an important source of micronutrients to the ocean, but atmospheric deposition fluxes remain poorly constrained in most ocean regions due to the limited number of field observations of wet and dry atmospheric inputs. Here we present the distribution of dissolved aluminium (dAl), as a tracer of atmospheric inputs, in surface waters of the Atlantic Ocean along GEOTRACES sections GA01, GA06, GA08, and GA10. We used the surface mixed layer concentrations of dAl to calculate atmospheric deposition fluxes using a simple steady state model. We have optimized the aerosol Al fractional solubility, dAl residence time within the surface mixed layer and depth of the surface mixed layer for each separate cruise to calculate the atmospheric...

Atmospheric deposition is an important source of micronutrients to the ocean, but atmospheric deposition fluxes remain poorly constrained in most ocean regions due to the limited number of field observations of wet and dry atmospheric inputs. Here we present the distribution of dissolved aluminium (dAl), as a tracer of atmospheric inputs, in surface waters of the Atlantic Ocean along GEOTRACES sections GA01, GA06, GA08, and GA10. We used the surface mixed-layer concentrations of dAl to calculate atmospheric deposition fluxes using a simple steady state model. We have optimized the Al fractional aerosol solubility, the dAl residence time within the surface mixed layer and the depth of the surface mixed layer for each separate cruise to calculate the...

Autores: Leal,Daniela Piaz Barbosa; Dick,Deborah Pinheiro; Stahl,Anna Meike; Köppchen,Stephan; Burauel,Peter.
ABSTRACT: In Brazil, atrazine (ATZ) is widely applied to maize (Zea mays L.) fields for weed control. The presence of ATZ and its metabolites in soil and water matrices has become a matter of some concern for governmental authorities as well as for society at large. This study evaluated the patterns of ATZ degradation (mineralization, extractable and non-extractable ATZ residues, and metabolite formation) in a Brazilian Typic Paleudult. Soil samples from a cultivated area under a no-tillage system with a history of ATZ application were incubated with 14C-ATZ in both the presence and absence of straw cover on the soil surface, and the evolved 14CO2 was determined by liquid scintillation. Samples from an area with native vegetation, adjacent to the...

Auch Öko-Schweine stinken – Geruch und Ammoniakemissionen aus der ökologischen Tierhaltung messen und mindern
Provedor de dados: 21
Autores: Klöble, Ulrike.
As livestock farming in general, organic livestock farming contributes to emissions of ammonia, odour and particulate matter. Especially for yards and free ventilated housings there is only little knowledge on the magnitude of emissions. This often complicates authorization processes for constructing new or altering existing housings.  Main issues of the workshop are: requirements in authorization processes, measures to reduce emissions and emission measurement standards. Ongoing projects are presented and their relevance as well as knowledge gaps for organic farming are discussed.

Aufwertung in globalen Food Value Chains – Impulse zur Erreichung der nachhaltigen Entwicklungsziele
Provedor de dados: 21
Autores: Matheis, Tanja; Herzig, Christian.
Globale Wertschöpfungsketten versprechen großes Potenzial, um zur Erreichung gleich mehrerer nachhaltiger Entwicklungsziele (SDGs) beizutragen. In der Landwirtschaft hat die Integration von ProduzentInnen in Wertschöpfungsketten neue Arbeitsplätze im Anbau und in der Verarbeitung von Lebensmitteln geschaffen. An vielen Stellen führte die Eingliederung in den internationalen Lebensmittelhandel jedoch auch zu prekären Arbeitsplätzen, Zwangsarbeit und zu einem riskanteren Geschäftsumfeld für Landwirte. Das von Gereffi (2005), Barrientos et al. (2011) und anderen entwickelte Konzept des „Upgrading“ oder der „Aufwertung“ thematisiert diese Bedenken, indem es u.a. beschreibt, wie ProduzentInnen ihre Position innerhalb einer Wertschöpfungskette und damit ihre ...

Australian Summer Monsoon variability in the past 14,000 years revealed by IODP Expedition 356 sediments
Provedor de dados: 5
Autores: Ishiwa, Takeshige; Yokoyama, Yusuke; Reuning, Lars; Mchugh, Cecilia M.; De Vleeschouwer, David; Gallagher, Stephen J.
The International Ocean Discovery Program (IODP) Expedition 356 Site U1461 cored a Miocene to Holocene sedimentary sequence in the upper bathyal carbonate offshore northwestern Australia (NWA). The siliciclastic component of these strata is primarily derived from the Australian continent. Radiocarbon dating on macrofossils and planktonic foraminifera shows that the upper 14 m section at Site U1461 preserves Holocene sediments, recording regional climate variability. K/Ca ratios determined by X-ray fluorescence elemental analyses and %K determined by shipboard natural gamma ray analysis are interpreted as indicators of riverine run-off from the Australian continent. We document the consequences of the variability of the Australian Summer Monsoon (ASM) on...

Auswirkung der Schnittfrequenz bei Rotklee auf den Ertrag von Blattmasse, Rohproteingehalt und -ertrag
Provedor de dados: 21
Autores: Böhm, Herwart.
Futterleguminosen weisen in Blättern hohe Eiweiß- und Aminosäuren¬gehalte auf und könnten somit bei der Erreichung der 100%-Öko-Füttreung einen wesentlichen Beitrag leisten. Neben der Futterleguminosenart und der Sorte kann auch die Nutzungsfrequenz einen Einfluss haben. Hierzu werden am Thünen-Institut für ökologischen Landbau am Standort Trenthorst Feldversuche durchgeführt. Erste Ergebnisse zeigen, dass der Gesamtertrag bei höherer Nutzungsfrequenz zwar abnimmt, dafür jedoch der Blattanteil signifikant erhöht wird. Die Zielgrößen Blattertrag als auch Rohproteinertrag der Blattmasse liegen in beiden Nutzungssystemen auf gleichem Niveau.

Autores: Gattinger, Andreas; Skinner, Colin; Krauss, Maike; Mäder, Paul.
Despite the increase in organic cropland, knowledge on the impact of organic farming on soil-derived nitrous oxide (N2O) and methane (CH4) emissions is rather limited. To improve the knowledge base, N2O and CH4 fluxes were investigated in a 571 day lasting cropping sequence in the “DOK” field trial. Two organic and two non-organic farming systems and an unfertilized control were chosen. For the whole monitoring, the two organic systems combined emitted 40% less N2O than the two non-organic ones cumulated on area-scale. Yield-scaled cumulated N2O emissions were nearly 10% lower for the organic systems combined, despite the yield gap of 27%. We found that besides N input, management induced soil quality properties drive differences in N2O emissions between...

Autores: Johns, Julia; Mück, Ulrich; Knierim, Ute.
Auf 36 Betrieben wurden Auswirkungen von Herdencharakteristika, Haltungs- und Managementbedingungen auf hornbedingte Schäden bei behornten Milchkühen im Laufstall analysiert. Nach univariabler Vorselektion von potenziellen Einflussfaktoren wurden multiple lineare Regressionsmodelle angewandt. Im Grundsatz nahmen hornbedingte Schäden/Tier mit steigendem Behornungsgrad zu. Dennoch gab es auch voll behornte Herden mit sehr wenigen Schäden/Tier. Die Bedeutung der Rasse, des Fütterungs- und Eingliederungsmanagements für die Prävention hornbedingter Schäden wurde unterstrichen. Diese Faktoren zeigten häufiger einen Einfluss auf die Tiere als haltungsbezogene Aspekte.

Authentication of Virgin Olive Oil by Using Dielectric spectroscopy combined with Some Artificial Intelligence Methods
Provedor de dados: 111
Autores: Soltani, Mahmoud; Rashvand, Mahdi; Teimouri, Nima; Omid, Mahmoud.
Adulteration is a serious problem in the food industry. Olive oil is widely adulterated with other cheap edible oils such as sunflower and canola oils. Therefore, developing a low-cost, practical and rapid analytical method for detecting such adulteration in olive oil would be useful and needed.  In this research, we aimed to develop a dielectric measurement based system combined with complementary analytical intelligent techniques to recognize authentication of virgin olive oil from adulterated with vegetable oils (canola and sunflower). 192 sinusoidal signals in the range of 20 kHz and 20 MHz were feed into the cylindrical dielectric sensor filled with oil sample. Correlation based feature selection (CFS) was applied to select the most appropriate...

Measuring in situ soil fluxes of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) continuously at high frequency requires appropriate technology. We tested the combination of a commercial automated soil CO2 flux chamber system (LI-8100A) with a CH4 and N2O analyzer (Picarro G2308) in a tropical rainforest for 4 months. A chamber closure time of 2 min was sufficient for a reliable estimation of CO2 and CH4 fluxes (100% and 98.5% of fluxes were above minimum detectable flux - MDF, respectively). This closure time was generally not suitable for a reliable estimation of the low N2O fluxes in this ecosystem but was sufficient for detecting rare major peak events. A closure time of 25 min was more appropriate for reliable estimation of most N2O...

Autores: Gauci, Adam; Deidun, Alan; Montebello, John; Abela, John; Galgani, Francois.
Four sandy beaches on the island of Malta in the Central Mediterranean were regularly sampled for Large MicroPlastic (LMP) particles having a diameter between 1 mm and 5 mm, at stations located at the waterline and 10 m inshore. The 10975 extracted LMP particles were characterised (dimensions, surface roughness, colour) through unaided visual observation, microscopic analyses, and an algorithm developed within the current study. Two-thirds of the isolated particles were smooth and the majority of these belonged to the grey-white colour category, with a low degree of opaqueness and discolouration, and a high degree of transparency, suggesting that these were dominated by low-density polyethylene LMPs. Conflicting evidence concerning the relative residence...

ABSTRACT: Seedling production is an important step in the lettuce production system. However, there is a tendency to apply excessive irrigation at this stage. The aim of this study was to test the use of the Simplified Irrigation Controller (SIC) under two conditions: first, with the sensor installed in the substrate (measuring the soil water tension) and second, in the atmosphere (“atmospheric” - responding to vapor demand in the atmosphere) to control the irrigation of lettuce seedlings. The performance of the SIC was evaluated by monitoring plant traits. The lettuce seeds of the Regina cultivar were sown in styrofoam trays with commercial organic substrate. Both experiments were conducted under greenhouse conditions and evaluated under different SIC...

The experimental design was completely randomized with treatments consisting of six nutritional plans that included the initial, growth and termination phases and differed in relation to available phosphorus levels, and four replicates of 10 muscovy ducks each. The birds had weekly performance evaluations, and after 90 days, eight birds (four males and four females) in each treatment were slaughtered for evaluation of carcass traits. Data collected were subjected to Tukey test at 5% of significance. Differences were not observed...

Pot capacity (PC) is a direct method of determining field capacity (FC) for experiments with plantings in pots. The objective of this study was to evaluate different laboratory methods to determine field capacity and compare them with the pot capacity method. The experimental design was completely randomized (CRD), with nine treatments (methods of obtaining FC) and four replications, totaling 36 experimental plots. The mean values of moisture contents in the FC of the nine methods were compared, being eight empirically obtained and one directly in the greenhouse, defined as a control treatment (PC). The relative accuracy (RA) for all treatments was determined in relation to the control treatment. The estimation of the upper limit of available water in the...

Avaliação da citologia, genética e biologia reprodutiva de espécies de Paspalum para o estabelecimento de um programa de hibridações.
Provedor de dados: 14
Autores: FAVERO, A. P.
A pecuária brasileira ocupa aproximadamente 180 milhões de hectares do território nacional, sendo que 80% são ocupados com espécies forrageiras exóticas, principalmente do gênero Brachiaria. Tal realidade torna a pecuária altamente vulnerável a danos por praga e/ou doença, com consequências potencialmente desastrosas. Além disso, a grande maioria das cultivares são apomíticas e, geralmente, cada uma representa um só genótipo, em razão de seu sistema reprodutivo. Isso pode ser exemplificado com a infestação de cigarrinha-das-pastagens em Brachiaria decumbens na região CentroOeste (COSENZA, 1982) e a ?Síndrome da Morte Súbita? em pastagens de Brachiaria brizantha na Região Norte (BARBOSA, 2006).

Provedor de dados: 14
Autores: RODRIGUES, S. de M.; POLTRONIERI, M. C.; LEMOS, O. F. de; ARAUJO, S. M. B.; BOTH, J. P. C. L.
Cultivada de modo intensivo, a pimenteira-do-reino se adaptou muito bem às condições edafoclimáticas da região Norte do Brasil, principalmente quando cultivada em estacão de madeira. Esse tipo de tutor encarece o processo de instalação e ampliação dos pimentais, além de promover o corte de árvores da floresta fornecedora de madeira de lei. Como alternativa, desenvolveu-se o cultivo dessa espécie em tutor vivo, com uso de gliricídia (Gliricidia sepium L.), por favorecer o crescimento, o manejo e a condução das plantas de pimenteira-do-reino, além do tutor ser de fácil propagação e propiciar baixos custos de implantação dos pimentais. Entretanto, há necessidade especificamente de conhecer o comportamento de cultivares de pimenteira-do-reino cultivadas em...

Autores: Medeiros,S.O.; Silva,B.J.A.; Carneiro,A.L.; Ferreira Júnior,O.C.; Tanuri,A.
RESUMO FIV e FeLV são retrovírus associados principalmente com neoplasias. Dois testes rápidos são disponibilizados no Brasil para o diagnóstico dessas infecções: um kit de imunocromatografia de fluxo bidirecional (SNAP® Combo IDEXX) e um kit de imunocromatografia de fluxo lateral unidirecional (ALERE/BIONOTE Anigen Rapid). O objetivo deste estudo foi comparar o teste SNAP® com o teste ALERE. Amostras de sangue de 178 gatos foram testadas utilizando-se ambos os kits. A reação em cadeia de polimerase em tempo real (qPCR) foi empregada como método confirmatório para todos os resultados. O teste SNAP® apresentou sensibilidade e especificidade de 100% para FIV; a sensibilidade e a especificidade do teste ALERE foram de 96,15% e 98,68%, respectivamente. A...

Nos solos ácidos o alumínio (Al) encontra-se na forma de cátions, que são tóxicos para a grande maioria dos vegetais. O Al prejudica o desenvolvimento das raízes tornando as plantas mais suscetíveis a secas e doenças. Nestes solos a calagem é indispensável para cultivos agrícolas. As espécies de plantas do Cerrado toleram altas concentrações de Al e, assim, são fontes de biomoléculas com potencial biotecnológico para a aplicação na obtenção de plantas tolerantes ao Al. O objetivo deste trabalho foi avaliar o mecanismo de tolerância ao Al em espécies arbóreo-arbustivas nativas de uma área de Cerrado, visando apoiar a prospecção de genes e biomoléculas envolvidos com a tolerância ao Al. Foram realizados ensaios histoquímicos com hematoxilina em 31 espécies...

Provedor de dados: 14
Autores: RIBASKI, J.
Os sistemas de integração pecuária- -floresta representam uma alternativa economicamente viável que, entre outros benefícios ambientais e sociais, permite a diversificação de fontes de renda, com redução de risco financeiro. Assim, a conversão de áreas de pastagens em sistemas silvipastoris, usando espécies do gênero Eucalyptus com potencial para uso binário (lenha-serraria), poderá ser um importante diferencial competitivo do agronegócio regional, podendo gerar benefícios tanto para o setor pecuário quanto ao setor florestal, uma vez que estes sistemas de integração oferecem emprego e incremento da renda com maior eficiência e sustentabilidade do que a pecuária extensiva tradicional praticada na região.

Provedor de dados: 14
Autores: CAVALCANTI, P. R.; MOTTI, A. C. L.; REIS, W. V. A. dos; SILVA, L. G. da; NICACIO, A. C.; DIAS, F. R. T.; NOGUEIRA, E.; SILVA, J. C. B.
O uso de sêmen refrigerado na reprodução bovina tem ganhado destaque em consequência do aumento da inseminação artificial em tempo fixo (IATF) no Brasil, possibilitando a coleta pré-agendada e preparação do sêmen permitindo o melhor uso dessa biotécnica. A principal vantagem que o sêmen refrigerado apresenta é a maior viabilidade espermática, por não passar pelo processo de criopreservação. Recentemente, estudos mostraram maior taxa de prenhez quando comparado ao sêmen congelado, chegando a um aumento de 20% (SILVA et al., 2016, 2017, 2019). O estudo foi conduzido com objetivo de comparar três diluidores comerciais, sendo dois a base de gema de ovo e um a base de lecitina, durante 15 dias, analisando a viabilidade do sêmen refrigerado, com base na...

Nos últimos anos houve uma notável expansão das áreas de cultivo sob solos arenosos, principalmente nos Estados de Maranhão, Tocantins, Piauí e Bahia, Estados estes que compõem a nova fronteira agrícola no Brasil (Brasil, 2018). Isso foi possível, em partes, pela evolução das práticas de manejo, como o plantio direto (PD) e Integração Lavoura-Pecuária-Floresta (ILPF), que favorecem a maior produção e manutenção da matéria orgânica no solo, propiciando maior disponibilidade de nutrientes e água (Balbino et al., 2012; Gil et al., 2016). Dessa forma, tornou-se possível o uso de solos de textura arenosa que antes eram considerados de pouca relevância em regiões agrícolas, mesmo quando presentes em áreas favoráveis à mecanização, por causa de limitações de...

Background: Azaspiracids (AZAs) are marine toxins that are produced by Azadinium and Amphidoma dinoflagellates that can contaminate edible shellfish inducing a foodborne poisoning in humans, which is characterized by gastrointestinal symptoms. Among these, AZA1, -2, and -3 are regulated in the European Union, being the most important in terms of occurrence and toxicity. In vivo studies in mice showed that, in addition to gastrointestinal effects, AZA1 induces liver alterations that are visible as a swollen organ, with the presence of hepatocellular fat droplets and vacuoles. Hence, an in vitro study was carried out to investigate the effects of AZA1, -2, and -3 on liver cells, using human non-tumor IHH hepatocytes. Results: The exposure of IHH cells to...

Autores: CALVO,JORGE O.; RIGA,BERNARDO GONZALEZ.
Abstract We describe a dentary of a new titanosaur sauropod, Baalsaurus mansillai, gen. et sp. nov. from the Late Cretaceous of Patagonia, Argentina. The material comes from the Portezuelo Formation, Neuquén Group. Titanosaur sauropods lower jaws are scarce and only nine taxa with dentaries have been described. There are two types of morphology in titanosaur dentaries; “L” shaped or “U” shaped based on the shape, without a phylogenetic issue. In this paper; we recognize a new taxa, Baalsaurus mansillai, represented by an “L” shaped dentary with three apomorphic characters that are not present in other taxa: dentary alveoli with 10 teeth in the anterior ramus, a ventrally and anteriorly inclined symphysis and a wide ventral Meckelian groove surrounded by a...

Autores: Santos,Valquíria Oliveira dos; Viana,Alexandre Pio; Preisigke,Sandra da Costa; Santos,Eileen Azevedo.
ABSTRACT The present study aims to characterize the genetic diversity of Passiflora setacea, P. edulis, their hybrids, and first-backcross progenies, and to indicate promising recombinants for generation advancement in a breeding program for transferring resistance to cowpea aphid-borne mosaic virus (CABMV). Ninety-one genotypes were evaluated for 37 morphoagronomic descriptors. The traits were analyzed to obtain a distance matrix, based on the Gower algorithm, using the Ward-Modified Location Model (MLM) procedure for the composition of genetic groups. The adopted strategy led to the formation of five homogeneous groups, where groups I, III, and V comprised the parents P. setacea, P. edulis and interspecific hybrids, respectively, while groups II and IV...

Autores: Zhong,Juying; Li,Gonghua; Xu,Hong; Wang,Yan; Shi,Mingming.
The natural flavonoid glycoside baicalin (BA) produces a variety of pharmaceutical effects, particularly for psychiatric/neurological disorders. This study evaluated the behavioral and neuroprotective effects of BA in mice subjected to chronic unpredictable mild stress, a model of depression. BA (25 and 50 mg/kg) significantly increased sucrose consumption and reduced immobility times in the tail suspension and forced swim tests, demonstrating that BA alleviated depression-like behaviors. Moreover, BA reduced the levels of inflammatory cytokines, such as interleukin 1β, interleukin 6, and tumor necrosis factor α, in serum and in the hippocampus. BA also abrogated increases in NMDAR/NR2B and Ca2+/calmodulin-dependent protein kinase II, and the decrease in...

Bait traps remain attractive to euglossine bees even after two weeks: a report from Brazilian Atlantic forest
Provedor de dados: 92
Autores: Coswosk,Judson Albino; Soares,Elaine Della Giustina; Faria,Luiz R.R.
ABSTRACT Bait traps are effective and commonly used method in the studies of orchid bees. Important questions in the context of this method, including those related to bait dispersion, how long baits remain attractive, the distance from which males are supposed to be attracted to lures and so on, are still open subjects. Data on the attractiveness of bait traps that have remained in the field during two weeks in a large Atlantic forest preserve are presented. Four main results emerge from the data: (i) the abundance of specimens collected per day decreased in all the attractants as the traps were left on the field; (ii) despite this decrease, the absolute number of individuals collected after eight and fifteen days is remarkably, mostly in eugenol and...

Frailty is related to a decrease in the physiological reserves, which causes difficulties in maintaining homeostasis. An example of physiological mechanisms for cardiovascular homeostasis is the baroreflex. The aim of this study was to compare baroreflex among frail, prefrail, and nonfrail individuals, in supine and orthostatic positions. Community-dwelling older adults were evaluated and categorized into frail, prefrail, or nonfrail groups, according to frailty phenotype. The RR interval (RRi) and systolic blood pressure (SBP) series were recorded for 15 min in the supine and 15 min in the orthostatic positions. Mean and variance of RRi and SBP, and baroreflex evaluated by phase, gain (α), and coherence (K2) were determined. A two-way repeated measures...

Bayesian analysis of growth, stem straightness and branching quality in full-sib families of Eucalyptus globulus
Provedor de dados: 53
Autores: Mora,Freddy; Ballesta,Paulina; Serra,Nicolle.
ABSTRACT Eucalyptus globulus is one of the most commonly planted hardwood species for industrial use in various temperate regions around the world. The present study aimed to evaluate 62 full-sib families of E. globulus in one of the southernmost progeny trials of the species in the south of Chile. Estimates of genetic parameters for stem straightness, branching quality and growth traits were based on a Bayesian modelling approach using Gibbs sampling. A Bayes Factor (BF) analysis supported the hypothesis of significant additive genetic variation for all traits under study. Conversely, the BF supported a model with significant dominance effects for the diameter at breast height and stem volume, which explained up to 25% of the phenotypic variation. The...

Bayesian sequential procedure to estimate the viability of seeds Coffea arabica L. in tetrazolium test
Provedor de dados: 63
Autores: Brighenti,Carla Regina Guimarães; Cirillo,Marcelo Ângelo; Costa,André Luís Alves; Rosa,Sttela Dellyzete Veiga Franco da; Guimarães,Renato Mendes.
ABSTRACT: Tetrazolium tests use conventional sampling techniques in which a sample has a fixed size. These tests may be improved by sequential sampling, which does not work with fixed-size samples. When data obtained from an experiment are analyzed sequentially the analysis can be terminated when a particular decision has been made, and thus, there is no need to pre-establish the number of seeds to assess. Bayesian statistics can also help, if we have sufficient knowledge about coffee production in the area to construct a prior distribution. Therefore, we used the Bayesian sequential approach to estimate the percentage of viable coffee seeds submitted to tetrazolium testing, and we incorporated priors with information from other analyses of crops from...

Provedor de dados: 70
Autores: Mota,Vania C.; Andrade,Ednilton T. de; Leite,Daniel F.
ABSTRACT The success of confinement for dairy cattle in the compost barn model depends mainly on the management of the bed and consists of its turning. This paper characterises the spatial variability of the bed temperature in the compost barn confinement model, as well as verifying whether there was an effect on efficiency from turning the bed with different agricultural implements. The experiment was conducted during the summer and winter of 2016, with 8 days of collection in each period. Data were analysed with descriptive statistics methods and geostatistical modelling with semivariograms and kriging maps. The results of the t-test at a5% significance level indicated that, after turning the bed with the plough or rotary hoe, the temperature values were...

Bedding hygiene, cleanliness and lying behaviour  for heifers housed on wood chip or straw deep  bedding
Provedor de dados: 21
Autores: Johanssen, Juni Rosann E.; Sørheim, Kristin; Strøm, Turid; Brunberg, Emma.
The aim of this project was to compare the hygienic quality of the bedding, as well as the parasitic load, cleanliness and lying behaviour in heifers kept on either straw or wood chip deep bedding. Fourteen heifers kept in two pens were housed on straw or wood chip bedding for 43 days, after which the bedding material was switched for 43 additional days. Significantly more mould was found in wood chip than in straw and there was a tendency towards less yeast in wood chip. The heifers had a low faecal parasitic load. The results indicate that the wood chip treatment resulted in somewhat cleaner animals. The heifers had a significantly longer total lying time when kept on straw. In conclusion, wood chip deep bedding could be an option as bedding material,...

ABSTRACT The effect of four nitrogen levels (0, 40, 80 and 120kg N ha-1), applied before deferment on the beef cattle production and structural variables on Urochloa decumbens (signal grass) were assessed from January to October 2012 and from January to September 2013. A randomized block design with three replicates was adopted, in an arrangement of repeated measures in time (grazing period). An interaction effect between nitrogen level and grazing period was observed on extended-plant height and herbage mass. As the nitrogen levels were increased, extended-plant height, herbage mass, total herbage allowance, and efficiency of conversion of fertilizer into herbage were increased. Throughout the grazing period, pasture height, extended-plant height,...

Abstract: The objective of this work was to evaluate the effects of increasing the contents of total solids (TS) in whole milk, by adding increasing amounts of milk replacer powder, on the behavior of dairy heifers. Holstein-Gyr crossbred heifers (n = 60) were distributed in four treatments: 13.5, 16.1, 18.2, and 20.4% TS. From 5 to 55 days of age, heifers received 6 L per day of liquid feed, which was reduced by half from 56 to 59 days. Heifers were weaned at 60 days of age and monitored until 90 days, and their behavior was evaluated weekly. During gradual weaning and after weaning, heifer behavior was recorded 1 hour before and 1 hour after liquid feed was offered, and, during weaning, it was evaluated by the scan method. Heifers fed liquid feed...

ABSTRACT: Environmental enrichment is a dynamic process consisting of a set of activities designed to meet the ethological and psychological needs of animals. It stimulates the natural behavior of each animal species improving the well-being of the individual and avoiding the development of stereotyped behaviors. The present study aimed to assess the potential benefits that four different types of environmental enrichment would bring to the quality of life of shelter dogs. Twenty dogs were observed for 6 hours daily for 5 consecutive days in the first week in order to assess and document their behavior patterns in an experimental kennel. Between the second to the fourth week, 3 forms of game and 1 type of food enrichment were used in the first 4 days of...

Behavioral effects of Bj-PRO-7a, a proline-rich oligopeptide from Bothrops jararaca venom
Provedor de dados: 56

The heptapeptide Bj-PRO-7a, isolated and identified from Bothrops jararaca (Bj) venom, produces antihypertensive and other cardiovascular effects that are independent on angiotensin converting enzyme inhibition, possibly relying on cholinergic muscarinic receptors subtype 1 (M1R). However, whether Bj-PRO-7a acts upon the central nervous system and modifies behavior is yet to be determined. Therefore, the aims of this study were: i) to assess the effects of acute administration of Bj-PRO-7a upon behavior; ii) to reveal mechanisms involved in the effects of Bj-PRO-7a upon locomotion/exploration, anxiety, and depression-like behaviors. For this purpose, adult male Wistar (WT, wild type) and spontaneous hypertensive rats (SHR) received intraperitoneal...

Die Landwirtschaft spielt eine wichtige Rolle in der Erzeugung von Lebensmitteln sowie in der Bereitstellung und dem Erhalt von gesellschaftlichen Gemeingütern. Neben der Artenvielfalt, siehe Volksbegehren in Bayern, wird hierbei der Beitrag der Landwirtschaft zum Klimaschutz besonders stark und kontrovers diskutiert. Insbesondere die Frage, ob der Ökolandbau klimafreundlich oder „schlecht für das Klima“ ist, erregt viele Gemüter. Als Beitrag zu einer Versachlichung der Diskussion wird im Folgenden auf die Hauptpunkte der Kontroverse eingegangen und der Stand der Wissenschaft zusammengefasst.

Below- and aboveground production in cocoa monocultures and agroforestry systems
Provedor de dados: 21
Autores: Niether, Wiebke; Schneidewind, Ulf; Fuchs, Michael; Schneider, Monika; Armengot, Laura.
Farmers expect yield reduction of cash crops like cocoa when growing in agroforestry systems compared to monocultures, due to competition for resources, e.g. nutrients and water. However, complementarities between species in the use of resources may improve resource use efficiency and result in higher system performance.  Cocoa trees have a shallow rooting system while the rooting characteristics of the associated trees are mainly unknown. This work investigates fine root distribution and production in five cocoa production systems: two monocultures and two agroforestry systems under conventional and organic farming, and a successional agroforestry system. In the organic systems a perennial leguminous cover crop was planted and compost was added, while...

ABSTRACT: Green propolis is found only in Brazil and due to its important biological characteristics, the food industry views it as a rich source of bioactive compounds. However, an extract must be produced for its application, which is difficult considering the rigid characteristics of raw propolis. Superfine grinding, a process capable of reducing particle size, enables the extraction of most bioactive compounds in propolis. This study evaluated the influence of grinding on size characteristics, antioxidant and antifungal properties of Brazilian green propolis for food preservation. The propolis powder was produced through six different types of grinding (different sieves and rpm), and its quality was evaluated by scanning electron microscopy-energy...

Benguela Niños and Benguela Niñas in forced ocean simulation from 1958 to 2015
Provedor de dados: 5
Autores: Imbol Koungue, Rodrigue Anicet; Rouault, Mathieu; Illig, Serena; Brandt, Peter; Jouanno, Julien.
A systematic study of Benguela Niño and Benguela Niña events during 1958 to 2015 including those that developed before the satellite era (1982) is carried out using an ocean general circulation model in combination with a linear equatorial model. Altogether, 21 strong warm and cold anomalous coastal events are identified among which 6 undocumented extreme coastal events are reported. Results suggest that most of these extreme coastal events including the newly identified ones are linked to remote equatorial forcing via mode 2 equatorial Kelvin waves. The latter propagates after approaching the African coast poleward as coastally trapped waves leading surface temperature anomalies along the Angola‐Benguela current system by 1 month. 1‐2 months before the...

Benthic foraminifera as tracers of brine production in Storfjorden “sea ice factory”
Provedor de dados: 5
Autores: Fossile, Eleonore; Nardelli, Maria Pia; Jouini, Arbia; Lansard, Bruno; Pusceddu, Antonio; Moccia, Davide; Michel, Elisabeth; Péron, Olivier; Howa, Hélène; Mojtahid, Meryem.
The rapid response of benthic foraminifera to environmental factors (e.g., organic matter quality and quantity, salinity, pH) and their high fossilisation potential make them promising bio-indicators for the intensity and recurrence of brine formation in Arctic seas. Such approach, however, requires a thorough knowledge of their modern ecology in such extreme settings. To this aim, seven stations along a N–S transect across the Storfjorden (Svalbard archipelago) have been sampled using an interface multicorer. This fjord is an area of intense sea ice formation characterised by the production of Brine-enriched Shelf Waters (BSW) as a result of a recurrent latent-heat polynya. Living (Rose Bengal stained) foraminiferal assemblages were analysed together with...

Benthic Foraminifera in Arctic Methane Hydrate Bearing Sediments
Provedor de dados: 5
Autores: Dessandier, Pierre-antoine; Borrelli, Chiara; Kalenitchenko, Dimitri; Panieri, Giuliana.
Benthic foraminifera have been widely used as proxy for paleo-methane emissions, mainly based on their stable isotopic signature. In cold seeps, the ecology of these organisms remains uncertain, in particular their ability to thrive during active phases of seepage. In this study, we evaluate the benthic foraminiferal response to methane seepage in Arctic sediments. We do so by examining living and dead benthic foraminiferal assemblages (&gt;63 mu m) of 11 push cores collected in two of the most active pockmarks (Lunde and Lomvi) along Vestnesa Ridge, offshore western Svalbard. Benthic foraminiferal assemblages are interpreted in the context of sediment geochemistry, seafloor images, and pore water analyses, which are used to characterize the different...

Provedor de dados: 5
Autores: Oleszczuk, Barbara; Michaud, Emma; Morata, Nathalie; Renaud, Paul E.; Kędra, Monika.
The aim of this study was to assess bioturbation rates in relation to macrozoobenthos and environmental variables in the Svalbard fjords, Barents Sea and Nansen Basin during spring to summer transition. The results showed differences in benthic community structure across sampled area in relation to sediment type and phytopigment content. Fjords, Barents Sea and the shallow parts of Nansen Basin (&lt;400 m) were characterized by high functional groups diversity, and by biodiffusive and non-local rates ranging from 0.05 to 1.75 cm−2 y−1 and from 0.2 to 3.2 y−1, respectively. The deeper parts of Nansen Basin, dominated by conveyors species, showed only non-local transport rates (0.1–1 y−1). Both coefficients intensity varied with benthic biomass. Non-local...

Benzyl isothiocyanate inhibits invasion and induces apoptosis via reducing S100A4 expression and increases PUMA expression in oral squamous cell carcinoma cells
Provedor de dados: 56
Autores: Ma,Lei; Chen,Yongjun; Han,Rui; Wang,Shuangyi.
Benzyl isothiocyanate (BITC) has been shown to inhibit invasion and induce apoptosis of various types of cancer. However, its role on human oral squamous cell carcinoma (OSCC) cells is still not well elucidated. In the present study, we investigated the effect of BITC on apoptosis and invasion of SCC9 cells, and its underlying mechanisms in vitro and in vivo. SCC9 cells were exposed to BITC (5 and 25 μM) for 24 and 48 h. Cell growth, apoptosis, invasion, and migration were detected in vitro by MTT, FITC-conjugated annexin V/propidium iodide staining followed by flow cytometry, Matrigel-coated semi-permeable modified Boyden, and wound-healing assay. S100A4, PUMA, and MMP-9 expressions were detected to investigate its mechanisms. Xenotransplantation...

Berücksichtigung von Bodenvariabilität bei der Kalk-Ausbringung
Provedor de dados: 21
Autores: Kling, Charlotte.
In Brandenburg ist die räumliche Variabilität der kalkungsrelevanten Bodenparameter Textur, pH und Humus so groß, dass durch Beprobungen auf 3-5 ha Teilflächen gemäß den VDLUFA-Empfehlungen Unterschiede nur unzureichend erfasst werden. Dies bedingt bei pH-anspruchsvollen Kulturen, wie Luzerne und Kleearten, heterogene Bestände und einen geringeren Vorfruchtwert. Gerade im Ökolandbau ist es daher wichtig, kleinräumige pH bedingte Probleme zu erkennen und Methoden zu entwickeln, die ortsspezifisches Kalkmanagement ermöglichen.  Im Rahmen des EIP-Agri-Projektes „pH-BB: Präzise Kalkung in Brandenburg“ kommen zwei mobile Sensorplattformen auf einem ökologischen und zwei konventionellen Betrieben zum Einsatz.

Der Einkauf von Öko-Lebensmitteln hat in den letzten Jahren deutlich zugenommen. Insbesondere Milch, Gemüse und Eier werden häufig in ökologischer Qualität gekauft. Bei anderen Produktgruppen, wie beispielsweise Süßigkeiten und Käse, wird noch relativ selten zur Öko-Variante gegriffen. Es scheint als würden die typischen Kaufmotive, wie gesundheitliche, geschmackliche Vorzüge oder Umweltfreundlichkeit, nicht zum Kauf der ökologischen Variante bei diesen Produktgruppen führen. Angesichts der immer weiteren Ausdehnung der Produktpalette von Öko-Lebensmitteln in Discountern und Supermärkten, ist es relevant, die Bestimmungsgründe für den Kauf verschiedener Öko-Produktgruppen zu identifizieren.

Nitrogen (N) and phosphorus (P) limitations induce neutral lipid accumulation and membrane lipid remodeling in the domesticated oleaginous microalga Tisochrysis lutea. This study compared growth, photosynthetic activity, biochemical and transcriptional responses of T. lutea throughout batch cultures under N or P limitation compared with non-limiting nutrient condition (NP). The results show that, under N limitation, the breakdown and re-use of cellular N-containing compounds contributed to carbohydrates and further triacylglycerol (TAG) accumulation, where the accumulation of docosahexaenoic acid (DHA) in neutral lipids might mainly be derived from the recycling of membrane polar lipids. Conversely, P limitation did not hinder the photosynthetic capacity;...

Autores: Planner, Anna-Theresa; Koch, Robert; Degen, Barbara.
Schafwolle wird im Zierpflanzenanbau als organischer Dünger eingesetzt. Bei der Erzeugung von Frühjahrsblühern (Bellis perennis und Myosotis sylvatica) wurde die vollständige Bevorratungsdüngung mit Schafwollpellets in drei verschiedenen Größen und mit geschnittenem Schafwollvlies getestet. Mit einer Düngungshöhe von 6-10 kg Schafwolle/m³  bei B. perennis und 10 kg/m³ bei M. sylvatica konnten gute Pflanzenqualitäten erzielt werden. Düngung mit kleinen Pellets führte zum höchsten Nmin-Gehalt im Substrat und zum besten Pflanzenwachstum, welches durch die Messung von Frischmasse, Höhe und Durchmesser der Pflanzen ermittelt wurde. Pflanzengesundheit und Gesamteindruck wurden bei Düngung mit geschnittenem Schafwollvlies am besten bewertet.

Autores: Treu, Hanna; Sanders, Jürn.
Die gesellschaftlichen Kosten der Landwirtschaft sind von großer Bedeutung. Können diese gesellschaftlichen Kosten näher ökonomisch bestimmt werden? Inwiefern unterscheidet sich der Ökolandbau von der konventionellen Landwirtschaft in dieser Hinsicht? Im Rahmen einer Literaturanalyse wurden sieben Bereiche gesellschaftlicher Leistungen in Bezug auf diese Fragen analysiert. Die Analyse ergab, dass die gesellschaftlichen Kosten sehr hoch sind, aber dass sie sich mit der bestehenden Literatur nicht genau abschätzen lassen. Desweiteren schnitt der Ökolandbau in den Studien, die einen ökonomischen Vergleich der gesellschaftlichen Leistungen von Ökolandbau und konventioneller Landwirtschaft durchgeführt haben, besser ab.

The current V3.1 Argo netCDF format that produces a pair of core- and b- profile files per cycle, with N_PROF &gt; 1, allows storage of all profile information returned from BGC floats, in a manner that is as close to float output as possible. These can include multiple full-depth profiles with different pressure levels, multiple shallow profiles with different pressure levels, and recording of spatial and/or temporal delays between the CTD and various BGC sensor outputs. The advantage of this data management approach is that float outputs are faithfully recorded, so that any reprocessing demands that require access to the raw data can be met with ease. However, when measurements from multiple sensors are not aligned during onboard processing by the...

The French initial assessment of the Marine Strategy Framework Directive (MSFD) highlighted the lack of reliable data concerning offshore areas. During the planning of the monitoring programmes, the scientists therefore proposed to partially cover this gap by using existing fisheries research vessel surveys deployed for the purposes of the Common Fisheries Policy (CFP). Testing phases from October 2013 to August 2015 explored ways of improving the effectiveness of these surveys and making them better suited to delivering the information needed for MSFD. The process became operational at the beginning of the year 2016 and six fisheries research surveys henceforth collect new data, with or without additional sampling techniques. This report provides an...

Bimodal zircon ages from Natash volcanics (southeast Egypt) and the link between eruption mechanisms and Late Cretaceous tectonics
Provedor de dados: 5
Autores: Abu El-rus, Mohamed Ali; Paquette, Jean-louis; Chazot, Gilles; Vannucci, Riccardo.
Trachyte plugs from the Natash volcanic field have been precisely dated using in situ U-Pb geochronology on zircon grains at similar to 93Ma. Available zircon ages thus suggest that the overall volcanic history at Natash was probably shorter than previously estimated based on Rb-Sr and K-Ar ages, which are more sensitive to element mobility. Basaltic flows and trachyte plugs were produced by a largely synchronous, Upper Cretaceous volcanic activity that occurred in the Natash area at the onset of the extensional fracturing that preceded and accompanied the doming of the Afro-Arabian Shield. Extraction and eruption of volumetrically dominant basalts from deeper lithospheric levels were ruled by major NW-SE strike-slip faults, whereas both major and...

ABSTRACT The aim of this study was to develop and implement a linear-programming model (LP) that provides as its result a schedule with the best selection of crops in each plot per period, and with the greatest weight gain for each animal. The linear-programming model was developed from empirical work carried out by Alvarenga and Gontijo Neto (2008) in an area of 24 hectares of Embrapa Milho e Sorgo, in Sete Lagoas, Minas Gerais (MG). For the computational implementation of the model, it was necessary to have data on agricultural suitability and animal weight gain for each period and for each plot. In order to test the developed mathematical model, values were randomly generated for agricultural suitability and for animal weight gain using the MATLAB...

Abstract: Ackee (Blighia sapida K. D. Koenig) is an exotic fruit widely consumed in the Caribbean countries. While there is extensive research on the presence of hypoglycin A, other bioactive compounds have not been studied. We identified and quantified the changes in bioactive molecules (total phenol, ascorbic acid, hypoglycin A, squalene, D: A-Friedooleanan-7-ol, (7.alpha.), and oleic acid), antioxidant potential, and volatile compounds during two stages of ripe. A clear reduction in hypoglycin A, ascorbic acid, and total polyphenols during the maturation process were observed. On the contrary, oleic acid, squalene, and D: A-Friedooleanan-7-ol, (7.alpha.) contents increased about 12, 12, and 13 times, respectively with advancing maturity. These bioactive...

Autores: Kęska,Paulina; Wójciak,Karolina Maria; Stadnik,Joanna.
ABSTRACT: This research investigated the potential of beef products with acid whey to release bioactive peptides and thereby emphasize their health-promoting potential. Peptide sequences were isolated and identified by liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS). Firstly, the antihealth properties (toxicity, allergenicity) of the peptides were estimated based on the peptide sequences. Next, their health-promoting potential was demonstrated based on an in silico analysis by determining their bioactivity scores (PeptideRanker). Their various biological actions were also determined using BIOPEP-UWM tools. We presented peptide sequences with properties relevant to ensuring good health and well-being, including cardiovascular...

Abstract: We have established how natural compounds from green propolis collected by the species Apis mellifera act against the growth of Pythium aphanidermatum. On the basis of mass spectrometry (Q-ToF MS), we determined that Artepillin C, the major constituent of green propolis, underlies the effect and displays activity against P. aphanidermatum at a minimal inhibitory concentration of 750 µg.mL-1. Biophysical studies based on model membranes showed that this inhibitory effect may be linked with a membrane-related phenomenon: Artepillin C increases the permeability of membranes with relatively high fluidity in their lateral structure, a feature that is in line with the lipid composition reported for the cytoplasmic membrane of P. aphanidermatum....

Provedor de dados: 87
Autores: DIESEL,F.; TREZZI,M.M.; VIDAL,R.A.; BARANCELLI,M.V.J.; MIZERSKI,P.H.F.
ABSTRACT: Persistence of an herbicide is defined as the ability to maintain the integrity of its molecule and chemical, physical, and phytotoxic properties in the environment where it was applied. Knowledge of persistence has implications both for the toxicity generated on species grown in succession and for the period in which the herbicide controls weeds. This study aimed to assess the persistence of the herbicide saflufenacil in an Oxisol by means of bioassays. Two experiments with the application of 29.4 g ha-1 of saflufenacil were carried out under field conditions: the first in the 2011/2012 season and the second in the 2012/2013 season. Soil samples were collected at depths of up to 10 cm at different times after application. Subsequently, two...

Biochar and Trichoderma harzianum for the Control of Macrophomina phaseolina
Provedor de dados: 52
Autores: Araujo,Alyson Silva de; Blum,Luiz Eduardo Bassay; Figueiredo,Cícero Célio de.
Abstract This study is based on the importance of biological control methods and the lack of information on the effect of biochar (BCH) from sewage sludge associated or not with Trichoderma harzianum on the control of Macrophomina phaseolina in the bean crop (Phaseolus vulgaris, cv. BRS Estilo). Biochar from sewage sludge, pyrolyzed at 500 ºC and used in low concentration (0.5%), has a direct effect on the in vitro control of M. phaseolina. However, higher BCH concentrations stimulated the growth of the pathogen. In culture medium with or without BCH, T. harzianum (strain 1306) inhibited the mycelial growth of M. phaseolina. The addition of BCH + T. harzianum reduced the deleterious effects caused by M. phaseolina on bean plants. This study demonstrated...

Autores: Santos,Sara Ramos dos; Lustosa Filho,José Ferreira; Vergütz,Leonardus; Melo,Leônidas Carrijo Azevedo.
ABSTRACT The use of fertilizers with some degree of protection of the phosphate ions can reduce soil adsorption and increase the absorption by plants, increasing the efficiency of phosphorus (P) fertilization. This study aimed to evaluate the performance of a phosphate fertilizer associated with biochar in granules in a P-fixing soil in a greenhouse experiment. Biochars were produced from two sources of biomass: sugarcane bagasse (SB) and wood sawdust (WS), which were pyrolysed at two temperatures (350 °C and 700 °C). After chemical and physical characterization, the biochar samples were granulated with triple superphosphate (TSP) in a 3:1 ratio (TSP: biochar). The agronomic evaluation of the fertilizers was carried out by two successive maize crops (Zea...

Abstract The aim of this work was to study the myofibril proteins and collagen fraction changes in broiler chickens PSE (pale, soft, exudative) meat during ageing and their relationship to meat quality. The results presented an increase of myofibril proteins and collagen solubility promoted by the enhanced proteases activities during storage. Ultramicroscopically, the PSE meat samples revealed intracellularly a sarcomere super contraction and lacunas within the A and I bands while Z-lines appeared very dense and fragmented in comparison to normal samples. This observation was noticed already at 4h storage while extracellularly collagen fibrils decreased visually within the endomysium only after 24h of conditioning. These results influenced the quality as...

ABSTRACT The genetic diversity of pepper genotypes is usually evaluated based on morphological and molecular descriptors. However, studies using biochemical descriptors of peppers are still incipient. Thus, the objective of this study was identify biochemical descriptors of Capsicum spp. with antioxidant action, most responsive to the selection of superior genotypes, and evaluate the correlation between concentrations of the parameters using principal components analysis. The experiment was conducted in the city of Cáceres, southwest Mato Grosso, Brazil. Seventy-eight pepper accessions from the Active Germplasm Bank of UNEMAT were planted in randomized block design. The harvested fruits were immersed in liquid nitrogen for two minutes, and the following...

ABSTRACT The objective of the present study was to establish the bioclimatic zoning by the temperature and humidity index (THI), considering a historical period and a future scenario, in order to represent the thermal environment for broiler breeding in the State of Minas Gerais. A historical series (1976 - 2014) of THI minimum, average and maximum calculated based on data from 48 conventional meteorological stations was used, belonging to the National Institute of Meteorology of the State of Minas Gerais. The analysis of the temporal series was based on the Mann-Kendall test and linear regression. A geostatistical analysis was also carried out to determine the comfort zoning of broilers as a function of the THI intervals. In this way, the THI spatial...

Autores: MELO,MARÍA CECILIA; DELLAPÉ,PABLO M.
Abstract: A new genus of Larginae (Largidae), Parvacinocoris, is described to include a new species from Argentina and Paraguay, and P. stehliki (Doesburg) new combination, a species previously placed in Acinocoris, previously known from Surinam and Venezuela and in this paper recorded also from Brazil, Colombia and Guatemala. This new genus is similar to Acinocoris however it may be separated by the smaller size, the shorter antennae, the immaculate abdominal sterna, the shape of the parameres, and the presence of a pair of hook‐like processes on the aedeagal conjunctiva. Photographs of dorsal and lateral habitus of both sexes as well as the male genitalia of the new species are included.

Autores: MAGNUSSON,WILLIAM E.
Abstract: In this review I focus on what we need to know to make decisions relevant to land-use planning. I discuss four questions: What information about the distribution of biodiversity is available to decision makers? What sort of information is required at a local scale? Can we use species-distribution modeling to compensate for the lack of empirical information at larger scales? Can we use surrogates based on remote sensing for all our decisions? To be effective, biodiversity information needs to be based on standardized sampling with data made available during the initial planning phases of infrastructure projects, which are now based only on engineering or social considerations and occur several decades before construction starts. The RAPELD method...

Autores: Silva,Carlos Eduardo de Farias; Bertucco,Alberto.
Abstract The development of new technologies which increase the production of biofuel without directly compete with food production is required. Microalgal biomass has recently been in the highlight. The role of this biomass is here discussed within the concept of biorefinery and industrial sustainability of bioethanol production. The process of cultivation in order to accumulate around 50% of carbohydrates in the biomass (dry weight) and the importance of water and nutrient recycling are reviewed. Saccharification of biomass using enzymes or acids and alternative processes such as hydrothermal liquefaction and flash hydrolysis are addressed. Since the main monosaccharide in microalgal biomass is glucose, high rates of hydrolysis and fermentation were,...

ABSTRACT:  Prototheca spp. have been reported as an emergent environmental mastitis pathogen in several countries. Biofilm formation is a significant factor associated with different degrees of virulence developed by many microorganisms, including Prototheca spp. The present study aimed to compare two growth conditions and two staining dyes to determine which combination was more appropriate to evaluate qualitatively and quantitatively the production of biofilm by P. zopfii. Biofilm formation was evaluated in polystyrene microplates under static and dynamic growth conditions and staining with crystal violet or cotton blue dye. All P. zopfii isolates from cows with mastitis were classified as biofilm-producers in all growth conditions and staining. The...

Autores: FRANCO,Ángel G.; CADAVID,Luis F.; ARÉVALO-FERRO,Catalina.
ABSTRACT Many sessile marine invertebrates have life cycles involving the development of larvae that settle on specific substrates to initiate metamorphosis to juvenile forms. Although is recognized that bacterial biofilms play a role in this process, the responsible chemical cues are beginning to be investigated. Here, we tested the role of substrate-specific bacteria biofilms and their Quorum Sensing Signaling Molecule (QSSM) extracts on chemotaxis and settlement of larvae from Hydractinia symbiolongicarpus, a hydroid that grows on gastropod shells occupied by hermit crabs. We isolated and taxonomically identified by 16S rDNA sequencing, 14 bacterial strains from shells having H. symbiolongicarpus. Three isolates, Shigella flexneri, Microbacterium...

Abstract Advances in energy demand in rural areas cannot be dissociated from agricultural modernization, large estates, mechanization of labor and reduced investment in small production. The use of biogas together with biomass are the most cost-effective ways for the small producer, as it has a high calorific value. In the case of biogas the procedure is performed by combining a compressor and a chiller, allowing the gas enter the reactor and burn together with the air stream. The use of these techniques is an auxiliary way to reduce the cost of the producer to produce a certain crop, besides allowing a participation in the final energy supply, so that the utilities have an alternative to distribute the surplus energy to another region, serving thus a...

Surface ocean phosphate is commonly below the standard analytical detection limits, leading to an incomplete picture of the global variation and biogeochemical role of phosphate. A global compilation of phosphate measured using high-sensitivity methods revealed several previously unrecognized low-phosphate areas and clear regional differences. Both observational climatologies and Earth system models (ESMs) systematically overestimated surface phosphate. Furthermore, ESMs misrepresented the relationships between phosphate, phytoplankton biomass, and primary productivity. Atmospheric iron input and nitrogen fixation are known important controls on surface phosphate, but model simulations showed that differences in the iron-to-macronutrient ratio in the...

By altering the phenotypic properties of their hosts, endolithic parasites can modulate the engineering processes of marine ecosystem engineers. Here, we assessed the biogeographical patterns of species assemblages, prevalence and impact of endolithic parasitism in two mussel species that act as important ecosystem engineers in the southern African intertidal habitat, Perna perna and Mytilus galloprovincialis. We conducted large-scale surveys across three biogeographic regions along the South African coast: the subtropical east coast, dominated by the indigenous mussel, P. perna, the warm temperate south coast, where this species coexists with the invasive Mediterranean mussel, M. galloprovincialis, and the cool temperate west coast dominated by M....

Biogeography of the endosymbiotic dinoflagellates (Symbiodiniaceae) community associated with the brooding coral Favia gravida in the Atlantic Ocean
Provedor de dados: 5
Autores: Teschima, Mariana M.; Garrido, Amana; Paris, Alexandra; Nunes, Flavia; Zilberberg, Carla.
Zooxanthellate corals live in symbiosis with phototrophic dinoflagellates of the family Symbiodiniaceae, enabling the host coral to dwell in shallow, nutrient-poor marine waters. The South Atlantic Ocean is characterized by low coral diversity with high levels of endemism. However, little is known about coral–dinoflagellate associations in the region. This study examined the diversity of Symbiodiniaceae associated with the scleractinian coral Favia gravida across its distributional range using the ITS-2 marker. This brooding coral endemic to the South Atlantic can be found across a wide range of latitudes and longitudes, including the Mid-Atlantic islands. Even though it occurs primarily in shallower environments, F. gravida is among the few coral species...

Biological control of fruit flies in Brazil
Provedor de dados: 86
Autores: Paranhos,Beatriz Jordão; Nava,Dori Edson; Malavasi,Aldo.
Abstract: Fruit flies are the main pests of fruit growing in Brazil. They have been managed predominantly with the use of insecticides applied as cover spray and or/as toxic baits. Currently, the trend of management strategies is toward the adoption of methods that cause the lowest environmental impact in large areas. In this context, biological control is an excellent option to be used together with other management strategies, such as sterile insects, because it leaves no residues, does not disturb nontarget pests, and can be permanent if the natural enemy establishes itself in the field. This review paper addresses the current knowledge on the biological control of fruit flies in Brazil, highlighting the great biodiversity of its natural enemies,...

Abstract Phytochemical content of plant extracts can be used effectively to reduce the metal ions to nanoparticles in one-step green synthesis process. In this study, six plant extracts were used for the synthesis of silver nanoparticles (AgNPs). Biologically synthesized AgNPs was characterized using UV-Vis Spectrophotometer, Field Emission Scanning Electron Microscope (FE-SEM), X-ray diffraction (XRD), Energy Dispersive X-ray spectroscopy (EDX) and Fourier Transform Infrared (FTIR) spectroscopy. The individual and combined effects of AgNPs and tetracycline against S. aureus and K. pneumoniae were assessed. Ginger, onion and sidr extracts supported AgNPs formation while arak, garlic and mint extracts failed to convert the silver ions to AgNPs. The present...

Autores: Pasinato,Joel; Redaelli,Luiza Rodrigues; Botton,Marcos; Jesus-Barros,Cristiane Ramos de.
ABSTRACT Bactrocera carambolae Drew &amp; Hancock (Diptera: Tephritidae), native of Southeast Asia, is present in Brazil but restricted to Amapá, Pará and Roraima, where it has quarantine pest status. The possible dispersion to other fruit producing regions of Brazil could cause damages, including for exportation, due to quarantine restrictions imposed by fruit importing countries. The objective of this work was to describe the biological parameters and calculate the fertility life table of B. carambolae on grape (Vitis vinifera L.) and acerola (Malpighia emarginata DC.). The experiment was conducted in the laboratory under controlled conditions. The mean number of punctures and the mean number of eggs per female on grapes were 1.48 ± 0.05 and 9.87 ± 0.36,...

Autores: Upadhyay,Jyoti; Rana,Mahendra; Bisht,Satpal Singh; Rana,Amita; Durgapal,Sumit; Juyal,Vijay.
Experiments were conducted to investigate the effects on health of pregnant female rats exposed to pesticides glyphosate and carbendazim. Glyphosate is used as herbicide and carbendazim as a fungicide; all are commercially available readily for various agricultural and domestic purposes. The hypothesis tested in this investigation is that pesticide exposure during pregnancy causes changes in biomarker responses like serum glucose level, total protein, total cholesterol, triglycerides, SGOT, SGPT, and billirubin level. Significant changes were observed in all above biomarker responses, when compared with the reference. Histopathology of skin and kidney of rat neonates showed marked damage. Degenerative changes and vacuolization with eroded capsule were...

The Water Framework Directive (WFD) currently supports chemical and ecological monitoring programmes in order to achieve the good water surface status. Although chemical and ecological assessments are necessary, they have some limitations. Chemical approaches focus on certain substances identified as priorities, but they do not take into account other potentially harmful substances and also ignore the hazards related to contaminant cocktails. On the other hand, while ecological approaches provide holistic information on the impairment of biological communities in ecosystems, they do not distinguish the role of contaminants in these alterations, and consequently do not allow the establishment of contaminant impact reduction plans. Consequently,...

Biomass and phosphorus content in giant bamboo cuttings influenced by phosphate fertilization
Provedor de dados: 22
Autores: Dunaiski, Felipe Antico; Pauletti, Volnei; Motta, Antônio Carlos Vargas; Gotz, Lenir Fátima.
Dendrocalamus asper, known as giant bamboo or bamboo-bucket, has been used as a substitute for wood and fiber, due mainly to its wide availability, rapid growth rate, short cycle and traditional use as construction material. In general, its cultivation is carried out on phosphorus-deficient soils, using vegetative propagation, mainly from cuttings. Thus, the aim of this study was to evaluate the effect of fertilization with phosphorus doses on the biomass allocation in roots, leaves and stems and on the level and content of P in leaves and roots of bamboo cuttings. The experiment was conducted in a greenhouse, using soil with low P content (2.4 mg dm-3). The treatments consisted of six doses of phosphorus (0, 20, 40, 80, 160 e 320 kg ha-1 of P2O5). The...

Biomass pellets from densification of tree leaf waste with algae
Provedor de dados: 111
Autores: Tippayawong, Nakorn.
Fallen tree leaves in urban or public areas are usually discarded or accumulated and piled in open spaces where blockages of drainage or accidental fire can occur, causing damages to public properties and the environment. These tree leaves are seasonally available biomass residues that may potentially be substituted or mixed with wood to produce biomass pellets. In this work, densification of eucalyptus and teak leaf waste was carried out using a cylindrical die. Several influential operating factors (temperature of 30 and 80oC, pressure of 100, 150 and 200 MPa, and addition of algae as binding agent at 10 to 20% w/w) were investigated with respect to mechanical properties of the biomass pellets such as mass and energy densities, and compressive strength....

Special attention has emerged towards biomass smoke-induced chronic obstructive pulmonary disease (COPD), providing new knowledge for prevention and therapeutic approach of non-smoker COPD patients. However, the understanding of biomass smoke COPD is still limited and somewhat controversial. The aim of the present study was to compare COPD exclusively caused by tobacco smoking with COPD exclusively caused by environmental or occupational exposures. For this cross-sectional study, COPD patients were recruited from outpatient clinics and formed two groups: non-smoker COPD group (n=16) with exposure to biomass smoke who did not smoke cigarette and tobacco smoker COPD group (n=15) with people who did not report biomass smoke exposure. Subjects underwent...

Biomasseabschätzung im ökologischen Feldfutterbau mittels drohnengestützten RGB-Aufnahmen
Provedor de dados: 21
Autores: Grüner, Esther; Möckel, Thomas; Wachendorf, Michael.
Monitoringansätze im ökologischen Futterbau, die den Biomasseertrag über den gesamten Betrieb abschätzen, ermöglichen es dem Landwirt, standortspezifische Managemententscheidungen zu treffen. Die pflanzliche Biomasse und ihre Höhe korrelieren miteinander, wodurch die Höhe des Bestandes zur Ertragsprognose verwendet werden kann. Fernerkundliche Messmethoden sind nützlich, um räumliche Informationen über die Pflanzenhöhe auch über größere Flächen zu erhalten. In dieser Studie wurde eine RGB-Kamera (rot, grün, blau), die an einem kleinen unbemannten Luftfahrzeug (Drohne) angebracht war, zur Ertragsabschätzung in einem ökologischen Futterbauexperiment verwendet. Das Experiment wurde 2016 mit zwei Leguminosen-Grasmischungen (Klee- und Luzernegras) sowie mit...

Die invasive Leguminose Lupinus polyphyllus (Vielblättrige Lupine) breitet sich in artenreichen Borstgrasrasen und Bergmähwiesen aus. Dort verdrängt sie gefährdete Rote-Liste Arten und verändert die Artenzusammensetzung. Wir führten ein Experiment durch um den Biomasseertrag und den Lupinenanteil an der Biomasse zu unterschiedlichen Nutzungszeitpunkten zu untersuchen. Zusätzlich wurde der Alkaloidgehalt der Lupinen ermittelt, da dieser einen Einsatz der Biomasse in der Tierernährung verhindern kann. Die Ergebnisse zeigten Bioamsseerträge vo 3,6 bis 3,9 t Trockenmasse pro Hektar und Lupinenanteile von ca. 30% im Mittel. Der Alkaloidgehalt in den Lupinen wies eine Spannweite zwischen 0,7 und 2,5% in der Trockenmasse auf und war signifikant abhängig vom...

Autores: Rocha,Murillo Grespan da; Barros,Flávio Margarito Martins de; Oliveira,Stanley Robson de Medeiros; Amaral,Lucas Rios do.
ABSTRACT: Knowing the spatial variability of sugarcane biomass in the early stages of development may help growers in their management decision-making. Proximal canopy sensing is a promising technology that can identify this variability but is limited to quantifying plant-specific parameters. In this study, we evaluated whether biometric variables integrated with canopy reflectance data can assist in the generation of models for early-stage sugarcane biomass prediction. To substantiate this assertion, four sugarcane-producing fields were measured with an active crop canopy sensor and 30 sampling plots were selected for manually quantifying chlorophyll content, plant height, stalk number and aboveground biomass. We determined that Random Forest and Multiple...

ABSTRACT The relationships between fish size and sagitta otolith measurements were calculated for the first time for 15 species belonging to six families from the northern Brazilian coast. A total of 220 fish were sampled from the bycatch landed by the bottom-trawl industrial shrimp-fishing fleet between August and September 2016. All species had strong relationships between otolith measurements and fish total length with the coefficient of determination (r 2) ranging between 0.71 and 0.99. The variable most strongly related to fish total length was found to be the sagittal otolith length (OL) with 98% of the variability. These relationships are a useful tool to estimate length and mass of preyed fish from otoliths found in stomach contents of marine...

Biofouling causes major economic losses in the maritime industry. In our site study, the Bay of La Paz (Gulf of California), biofouling on immersed structures is a major problem and is treated mostly with copper-based antifouling paints. Due to the known environmental effect of such treatments, the search for environmentally friendly alternatives in this zone of high biodiversity is a priority to ensure the conservation and protection of species. The aim of this work was to link chemical ecology to marine biotechnology: indeed, the natural defense of macroalgae and sponge was evaluated against biofoulers (biofilm and macrofoulers) from the same geographical zone, and some coatings formulation was done for field assays. Our approach combines in vitro and...

Bioplastics production from agricultural crop residues
Provedor de dados: 111
Autores: Samer, Mohamed.
Bio-based plastics have a huge market and a wide range of applications and then have become increased in economy and research. Due to the environmental hazard on all organisms and the pollution that happens in all natural resources such as air, water, plants and soil pollution and the limitation of quantity of fossil resources on our planet, the future cannot depend on petro-plastics. All fossil products should be replaced by bio-based products. The petro-plastics are one of the fossil products which should be replaced by bio-based plastics. In this study, potato peels were used to produce bioplastics by the extraction of the starch from the peels and adding some ingredients such as water, glycerin, vinegar and industrial colors with different ratios and...

Abstract Parque Estadual do Tainhas - PET (Tainhas State Park) is a protected area with significant extensions of natural grasslands located in highland grasslands of northeastern Rio Grande do Sul state, Brazil, and recognized as an Important Bird Area. Our aim was to record the bird species richness of PET with a greater sampling effort than previous studies at the site, including unpublished data such as occurrence status of most species and evidence of breeding of some of them in the park. We surveyed birds between 2012 and 2018 performing aleatory trails covering mainly the central portion of PET (1,500 ha). We also added records from published studies. We listed 208 species, of which 203 were recorded during our fieldwork (including 18 species of...

H.; Wolkenstein, Klaus; Strother, Paul K.; Woermer, Lars; Hefter, Jens; Nettersheim, Benjamin J.; Hoshino, Yosuke; Schouten, Stefan; Damste, Jaap S. Sinninghe; Nath, Nilamoni; Griesinger, Christian; Kuznetsov, Nikolay B.; Elie, Marcel; Elvert, Marcus; Tegelaar, Erik; Gleixner, Gerd; Hallmann, Christian.
Eukaryotic algae rose to ecological relevance after the Neoproterozoic Snowball Earth glaciations, but the causes for this consequential evolutionary transition remain enigmatic. Cap carbonates were globally deposited directly after these glaciations, but they are usually organic barren or thermally overprinted. Here we show that uniquely-preserved cap dolostones of the Araras Group contain exceptional abundances of a newly identified biomarker: 25,28-bisnorgammacerane. Its secular occurrence, carbon isotope systematics and co-occurrence with other demethylated terpenoids suggest a mechanistic connection to extensive microbial degradation of ciliate-derived biomass in bacterially dominated ecosystems. Declining 25,28-bisnorgammacerane concentrations, and a...

ABSTRACT The effects of different concentrations of oxygen and nitrous oxide on blood gas parameters in pigs maintained under spontaneous or pressure-controlled ventilation, with or without positive end-expiratory pressure (PEEP), were compared. Forty-eight pigs were randomly divided into six groups, submitted to different concentrations of compressed air or N2O, associated with different fractions of inspired oxygen (FiO2). The group subject to 30% of compressed air (GA30) showed the closest proximity to the physiological range of partial pressure (PaO2) expected for the species. For oxygen saturation (SaO2), the values obtained were below the lower physiological limit in the group administered 30% N2O (GN30). Use of PEEP positively interfered in PaCO2...

BMP4 Induces Cardiomyocyte Hypertrophy Through the Activation of ERK 1/2 Signaling Pathway in H9c2 Cells
Provedor de dados: 52
Autores: Yuan,Yu; Tao,Yezheng; Deng,Yongzhi; Ye,Qunhui; Lin,Bin; Wu,Lin.
Abstract Bone morphogenetic protein-4 (BMP4) is a member of the bone morphogenetic protein family which plays an important role in bone formation, inflammation and cardiac hypertrophy. The aim of this study was to investigate the underlying molecular mechanism that BMP4-induced cardiomyocyte hypertrophy. H9c2 cells were used to measure cell surface area and protein synthesis. Western blot was used to examine hypertrophic marker brain natriuretic peptide (BNP) protein expression and phosphorylation of ERK1/2. The results exhibited that cell surface area, protein synthesis and BNP protein expression were increased with BMP4 treatment. While PD98059 inhibited these effects of BMP4. In addition, BMP4 treatment increased phosphorylation of ERK1/2 in a time- and...

Body condition influences ontogeny of foraging behavior in juvenile southern elephant seals
Provedor de dados: 5
Autores: Orgeret, Florian; Cox, Samantha; Weimerskirch, Henri; Guinet, Christophe.
Ontogeny of diving and foraging behavior in marine top predators is poorly understood despite its importance in population recruitment. This lack of knowledge is partly due to the difficulties of monitoring juveniles in the wild, which is linked to high mortality early in life. Pinnipeds are good models for studying the development of foraging behaviors because juveniles are large enough to robustly carry tracking devices for many months. Moreover, parental assistance is absent after a juvenile departs for its first foraging trip, minimizing confounding effects of parental input on the development of foraging skills. In this study, we tracked 20 newly weaned juvenile southern elephant seals from Kerguelen Islands for up to 338 days during their first trip...

Body mass index and glucose variations during the night in free-ranging Artibeus planirostris (Chiroptera: Phyllostomidae)
Provedor de dados: 103
Autores: Azeredo,Luane Maria Melo; Ximenes,Monique Silva; Pereira,Kleytone Alves; Fracasso,Maria Paula Aguiar; Lopez,Luiz Carlos Serramo.
ABSTRACT Body condition is an important measure to estimate the energy reserve of an organism. Scientists frequently use body condition indices (BCIs) with morphometric measures but direct measurements, such as blood glucose, seem to be more reliable. We observed oscillations in the body condition and glucose indexes of individuals of Artibeus planirostris (Spix, 1823) during 13 nights in the field. We assume that if glucose levels are proportional to feeding state and body condition is a measure of energy reserve, blood glucose and BCI should be positively correlated and both are expected to increase during the night as the bats leave their diurnal roost to feed. To test this, we examined the relationship between blood glucose levels, BCI and reproductive...

Provedor de dados: 42
Autores: CAVALCANTE,WASTHENNY V.; PELLEGRINO,DANIEL M.
Abstract The Bohnenblust-Hille polynomial and multilinear inequalities were proved in 1931 and the determination of exact values of their constants is still an open and challenging problem, pursued by various authors. The present paper briefly surveys recent attempts to attack/solve this problem; it also presents new results, like connections with classical results of the linear theory of absolutely summing operators, and new perspectives.

Abstract Clinical research has shed the light on the relation between coagulation and inflammation. Coagulation cascade is activated in lung injury resulting in thrombotic and fibrotic lesions. Such a cascade is initiated by inflammation, then the two systems intense each other. New therapies that modulate coagulation and inflammation will be more successful than therapies targeting only one of them. Mesenchymal stem cells showed anti-inflammatory functions in animal models. The role of mesenchymal stem cells in methotrexate induced lung injury model was evaluated, but no studies scoped on the role of stem cells in coagulation associated with inflammation in such models. This study focuses on the therapeutic role of mesenchymal stem cells against the...

Bone marrow mononuclear cells versus mesenchymal stem cells from adipose tissue on bone healing in an Old World primate: can this be extrapolated to humans?

ABSTRACT In veterinary medicine, the cell therapy is still unexplored and there are many unanswered questions that researchers tend to extrapolate to humans in an attempt to treat certain injuries. Investigating this subject in nonhuman primates turns out to be an unparalleled opportunity to better understand the dynamics of stem cells against some diseases. Thus, we aimed to compare the efficiency of bone marrow mononuclear cells (BMMCs) and mesenchymal stem cells (MSCs) from adipose tissue of Chlorocebus aethiops in induced bone injury. Ten animals were used, male adults subjected, to bone injury the iliac crests. The MSCs were isolated by and cultured. In an autologous manner, the BMMCs were infused in the right iliac crest, and MSCs from adipose tissue...

Bonga shad (   Ethmalosa fimbriata   ) spawning tactics in an upwelling environment
Provedor de dados: 5
Autores: Baldé, Bocar Sabaly; Döring, Julian; Ekau, Werner; Diouf, Malick; Brehmer, Patrice.
Successful recruitment in small pelagic fish populations inhabiting upwelling zones is subject to variation in fecundity and is driven by spatial and temporal fluctuations in environmental conditions, that is, mainly sea surface temperature, salinity and food availability. These fluctuations in abiotic factors have stimulated small pelagic fish populations to exhibit specifically adapted spawning tactics. To better understand to what extent a short‐lived exploited fish species such as bonga shad Ethmalosa fimbriata has adapted to an upwelling environment, we have investigated the interrelationship between upwelling intensity as a proxy for productivity and population fecundity by means of a virtual population analysis. We found that females of intermediate...

RESUMO Este estudo objetiva reportar a ocorrência de apoptose in vivo induzida pelo veneno da serpente Bothrops alternatus em células musculares esqueléticas. Cinco coelhos machos, adultos, receberam 150μg/kg de veneno no músculo vasto lateral, enquanto outros cinco animais receberam 0,1% de BSA diluído em PBS no mesmo local. Após 12 horas, os animais foram eutanasiados, e amostras do local de inoculação foram coletadas para análise histopatológica. Foram evidenciadas necrose e hemorragia nas células musculares. Além disso, a análise imuno-histoquímica para identificação de caspase-3 ativada revelou marcações granulares e agregadas no citoplasma das células musculares, compatíveis com o processo de apoptose. Este é o primeiro relato que confirma o veneno...

Bottom trawling contribution to the spatio-temporal variability of sediment fluxes on the continental shelf of the Bay of Biscay (France)
Provedor de dados: 5
Autores: Mengual, Baptiste; Le Hir, Pierre; Cayocca, Florence; Garlan, T.
Based on experiments, a trawling-induced erosion dynamics was included in a 3D realistic and pre-validated hydro-sedimentary model so as to assess its contribution to the overall regional sediment dynamics in the specific case of the Bay of Biscay continental shelf. The effect of trawling was investigated throughout a 5-year period in terms of horizontal/vertical fluxes and changes in seabed mud content, and compared to the natural variability of sediment fluxes at different spatio-temporal scales. Trawling is shown in the model to significantly contribute to sediment re-suspension, and changes in the seabed at the scale of the shelf. The contribution of trawling to re-suspension is &gt;80% during the high fishing season at many locations on the outer...

ABSTRACT Bovine alphaherpesviruses 1 and 5 (BoHV-1/5) are main pathogens of respiratory, reproductive and neurological diseases in cattle. The aim of this study was to investigate the frequency of neutralizing antibodies against BoHV-1/5 in serum samples and to detect viral DNA in semen of bulls from beef cattle farms located in RS. A total of 372 serum and semen sample from bulls were collected in eighteen farms. Serum samples were submitted to virus neutralization (VN) assay, while semen samples were used to detect BoHV-1 and BoHV-5 DNA by PCR. VN results showed that BoHV-1/5 antibodies were detected in bulls of 66.7% (12/18) of the farms, 295 (79.5%) BoHV positive bulls, 287 for BoHV-1 and 234 for BoHV-; at 43 vaccinated bulls 72.1% (31/43) showing...

Bovine leptospirosis: most prevalent serogroups in the municipality of novo repartimento - Pará
Provedor de dados: 195
Autores: Guedes, I. B.; Araújo, S. A. A.; Souza, G. O.; Castro, J. F. P.; Souza-Filho, A. F.; Heinemann, M. B.
In cattle, leptospirosis is particularly manifested by reproductive disorders, leading to losses in the production of these animals. Once the disease is present in a herd, control becomes difficult, especially by the adaptation of the bacterium to the animal species and can become a reservoir and/or maintenance host, such as serovars of the Sejroe serogroup for cattle.

ABSTRACT This study aimed at evaluating bovine behavioral parameters managed in crowding pens built with modular panel of reforestation wood and homogeneous particle sheets of sugarcane bagasse and in conventional wooden crowding pens. The animals treated had their body surface temperature measured by the infrared thermography method and the behavior evaluated through the flight time parameters and the behavior score in the crowding pens. The results indicated that the animals managed in these buildings showed no difference in the behavioral parameters, but the mean and maximum superficial body temperatures were lower in the animals managed in the crowding pens of modular panel.

O estresse térmico por calor é um importante fator na redução da produtividade dos bovinos. A temperatura corporal, resultante da troca de calor com o ambiente, pode ser usada como índice de adaptação fisiológica, já que o aumento da temperatura significa que o animal está acumulando calor e, se o calor não for perdido, o estresse térmico pode se manifestar. Considerando a dificuldade, em relação a campo, de avaliação de parâmetros fisiológicos, como a temperatura retal (TR), índices ambientais podem ser utilizados, como o índice de temperatura e umidade (ITU) e o índice de temperatura de globo e umidade (ITGU). Neste trabalho, o objetivo foi verificar a tolerância ao calor de novilhas de diferentes grupos genéticos.

Brachionus rotundiformis Tschugunoff, 1921 from the Brachionus plicatilis species complex (Rotifera: Monogononta): A new record from Galápagos Archipelago, Ecuador
Provedor de dados: 84
Autores: López,Carlos; Steinitz-Kannan,Miriam; Stamou,Georgia; Michaloudi,Evangelia; Papakostas,Spiros; Fontaneto,Diego; Segers,Hendrik.
Abstract The presence of the rotifer species Brachionus rotundiformis from the B. plicatilis species complex in Lake Arcturo, a saline lake in the Genovesa Island of the Galápagos Islands, is here reported. This is the first record of the species for the rotifer fauna of Ecuador as well as of the species complex to the Galápagos Islands. This finding is consistent with the idea of high dispersion capacity, and of cosmopolitan distribution of this species complex. Because Genovesa Island is uninhabited, passive transport by wind currents and zoochory by migrant birds seem to emerge as the most plausible factors in this process of colonization. Integrative studies on the morphological variations, genetic, molecular, and ecological aspects are still required...

ABSTRACT:  It is estimated that by 2050 the world population will be 9 billion people; and therefore, the need for alternative sources of protein is inevitable, since conventional sources, such as beef, pork and poultry, will not be sufficient to meet the demand of population growth. Food that includes alternative sources of protein, such as insects, is a reality in countries of Latin America, Asia, Australia, Europe and Africa. This research presents the results of an exploratory study that analysed the food profile of 1,619 consumers in the five Brazilian regions (North, Northeast, Midwest, Southeast and South) as well as their perception, motivation and preferred form of edible insects. The data were analysed by cross-tabulation and expressed as...

Autores: Atrey,Kushangi; Sharma,Yogesh; Bodhey,Narendra K.; Singh,Bikesh Kumar.
Abstract Breast cancer is the most commonly witnessed cancer amongst women around the world. Computer aided diagnosis (CAD) have been playing a significant role in early detection of breast tumors hence to curb the overall mortality rate. This work presents an enhanced empirical study of impact of dominance-based filtering approach on performances of various state-of-the-art classifiers. The feature dominance level is proportional to the difference in means of benign and malignant tumors. The experiments were done on original Wisconsin Breast Cancer Dataset (WBCD) with total nine features. It is found that the classifiers’ performances for top 4 and top 5 dominant-based features are almost equivalent to performances for all nine features. Artificial neural...

Autores: Moreira, Heverton Luis; Savegnago, Rodrigo Pelicioni; Freitas, Luara Afonso; Lôbo, Raysildo Barbosa; Bezerra, Luiz Antônio Framartino; Paz, Claudia Cristina Paro de.
The objective of this study was to develop a bio-economic model for the estimation of economic values of economically important traits in a full-cycle beef cattle production system. The bio-economic model calculated economic values by simulating the impact of changes in the profit of the system consisting of a 1% increase in each trait of the breeding objective, while the other traits were kept constant. The bio-economic model was effective in estimating the sources of revenues and expenses of the production system. The estimated economic values were, in the order of importance for the full-cycle system, R$ 3.69 for male slaughter weight, R$ 3.63 for male weaning weight, R$ 3.58 for weaning rate, R$ 3.40 for female slaughter weight, R$ 2.30 for female...

Autores: Haug, Benedikt; Messmer, Monika M.; Enjalbert, Jérôme; Goldringer, Isabelle; Forst, Emma; Mary-Huard, Tristan; Hohmann, Pierre.
Introduction and methods   Crop mixtures of cereals and legumes have received recent attention in the scope of climate change and local protein supply.   Cereal-legume mixtures are known to increase yield and yield stability compared with pure crops. Thus dedicated breeding strategies for mixed cropping might become necessary. As a model crop, we compared 32 current European spring pea (Pisum sativum L.) and 8 current spring barley (Hordeum vulgare L.) cultivars for their yield performance in mixed and pure stands, with pea as the focal species. Trials were done as an incomplete factorial design (Fig. 1) at two locations in  Switzerland with two replications (Fig. 2). We calculated variance components for the general and specific mixing ability (GMA and...

ABSTRACT  Background: Breast cancer is the neoplasm with both the highest incidence and mortality rate among women worldwide. Given the known snake venom cytotoxicity towards several tumor types, we evaluated the effects of BthTX-I from Bothrops jararacussu on MCF7, SKBR3, and MDAMB231 breast cancer cell lines.  Methods:  BthTX-I cytotoxicity was determined via MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazoliumbromide assay. Cell death was measured by a hypotonic fluorescent solution method, annexin-V-FITC/propidium iodide staining and by apoptotic/autophagic protein expression. Cancer stem cells (CSCs) were quantified by flow cytometry using anti-CD24-FITC and anti-CD44-APC antibodies and propidium iodide.  Results:  BthTX-I at 102 µg/mL induced...

Abstract The purpose of the study was to develop a xenogenic bubaline diaphragm matrix (BDM) for abdominal hernia repair. A fresh diaphragm was decellularized using aqueous sodium dodecyl sulfate (SDS) solutions (0.5-4% w/v) over a period. Acellularity was confirmed histologically and characterized by Masson’s trichrome staining, scanning electron microscopy (SEM), DNA quantification, agarose gel electrophoresis, and Fourier-transform infrared spectroscopy. The BDM was used for clinical abdominal hernia repair in six cattle. Clinical, hemato-biochemical and antioxidant parameters were evaluated to assess biocompatibility of xenogenic BDM. Histologically, the diaphragm treated with 2% SDS for 48 h showed complete acellularity and orderly arranged collagen...

To facilitate the wider implementation of ecosystem modeling platforms and, thereby, to help advance ecosystem-based fisheries management (EBFM) worldwide, tools delivering a large quantity of inputs to ecosystem models are needed. We developed a web application providing OSMOSE ecosystem models with values for trophic, growth and reproduction parameters derived from data from two global information systems (FishBase and SeaLifeBase). Our web application guides the user through simple queries to extract information from FishBase and SeaLifeBase data archives, and it delivers all the configuration files necessary for running an OSMOSE model. Here, we present our web application and demonstrate it for the West Florida Shelf ecosystem. Our software...

Bulk water charges in the dairy industry: A case study of interstate basins in Minas Gerais, Brazil
Provedor de dados: 65
Autores: Lima,Luiz Paulo de; Spletozer,Aline Gonçalves; Jacovine,Laércio Antônio Gonçalves; Carvalho,Antonio Fernandes de.
ABSTRACT:  Water is an essential input for any agribusiness, used for various purposes such as hygiene procedures, heat exchangers and beverage formulation. Water charging, regulated in Brazil by the National Water Resources Policy (Federal Law 9.433/97), is an important issue for the food industry, since it may change the profile of food production costs. Thus, this article aimed to estimate the price increases in the dairy industry from the use of water charging and evaluate the potential benefit of this collection, comparing it to some planned investments in basins plans. We used a case study of a dairy that produced 1 t/d of mozzarella cheese in the state of Minas Gerais. Results indicated that water charging among the basins with current collection...

Butterflies (Lepidoptera: Papilionoidea) from the campos rupestres of Serra de São José, Minas Gerais, Brazil
Provedor de dados: 49
Autores: Henriques,Nathália Ribeiro; Beirão,Marina do Vale; Brasil,Ello; Cornelissen,Tatiana.
Abstract We provide the first inventory of butterfly species (Lepidoptera: Papilionoidea) in Serra de São José, Minas Gerais, Brazil. Serra de São José has elevations ranging from 800 m to 1,400 m above sea level; the butterflies were sampled using traps and entomological nets in seven plots along the altitudinal gradient. We recorded 647 butterflies belonging to 112 species and six families. We also recorded one threatened species and three endemic species for the Cerrado domain, which suggests that Serra de São José is an important refuge for butterfly conservation.

Autores: Melo,Douglas H. A.; Duarte,Marcelo; Mielke,Olaf H. H.; Robbins,Robert K.; Freitas,André V. L.
Abstract Despite being one of the groups most well studied in Brazil, the butterfly fauna of northeastern Brazil, especially north of the mouth of São Francisco River, is poorly known. The aim of this study was to inventory the butterfly fauna in a remnant of Atlantic Forest in the state of Pernambuco as a contribution to understanding the distribution of these insects. The study was carried out in a 384.7 hectares fragment of Parque Estadual Dois Irmãos, in the metropolitan region of Recife. The butterflies were sampled monthly with insect nets from August 2011 to July 2012 and from January to August 2016. Additional records were obtained from two entomological collections and from two previous visits to the area in July 2003 and August 2006. A total of...

Provedor de dados: 84
Autores: Soldati,Déborah; Silveira,Fernando Amaral da; Silva,André Roberto Melo.
Abstract This paper investigates the butterfly fauna of the ‘Serra do Rola-Moça’ State Park, Minas Gerais, Brazil. We evaluate i) the seasonal variation of species richness and composition; and ii) the variation in composition of the local butterfly assemblage among three sampling sites and between the dry and rainy seasons. Sampling was carried out monthly between November 2012 and October 2013, using entomological nets. After a total sampling effort of 504 net hours, 311 species were recorded. One of them is endangered in Brazil, and eight are probable new species. Furthermore, two species were new records for the region and eight considered endemic of the Cerrado domain. There was no significant difference in species richness between the dry and the...

Provedor de dados: 56
Autores: Cruz Junho,C.V.; Trentin-Sonoda,M.; Alvim,J.M.; Gaisler-Silva,F.; Carneiro-Ramos,M.S.
Inflammation plays an important role in the development of cardiovascular diseases (CVDs), suggesting that the immune system is a target of therapeutic interventions used for treating CVDs. This study evaluated mechanisms underlying inflammatory response and cardiomyocyte hypertrophy associated with bacterial lipopolysaccharide (LPS)- or heat shock protein 60 (HSP60)-induced Toll-like receptor (TLR) stimulation and the effect of a small interfering RNA (siRNA) against Ca2+/calmodulin-dependent kinase II delta B (CaMKIIδB) on these outcomes. Our results showed that treatment with HSP60 or LPS (TLR agonists) induced cardiomyocyte hypertrophy and complement system C3 and factor B gene expression. In vitro silencing of CaMKIIδB prevented complement gene...

Cadmium toxicity on seed germination and initial growth of chia
Provedor de dados: 3
Autores: Stefanello, Raquel; Viana, Bruna Boucinha; Neves, Luiz Augusto Salles das.
In recent years, there has been a growing concern related to soil and water contamination due to the constant dispersal of toxic metals. In addition to their ecotoxicological potential, these elements exhibit a cumulative character that favors their permanence in soil and passage to living organisms, which can lead to an ecological imbalance. Among toxic metals, cadmium (Cd) is an obstacle to agriculture because it can adversely affect food quality and human health, as well as diminish plant growth and productivity. Thus, the objective of this work was to evaluate the toxicity of cadmium on seed germination and initial growth of chia. The ecotoxicological effects of four Cd concentrations (15; 30; 45; and 60 mg L-1) were evaluated. The response variables...

Calculated Potential Bedload Versus Real Transported Sands along the Guadiana River Estuary (Spain-Portugal)
Provedor de dados: 5
Autores: Morales, Juan A.; Lozano, Claudio; Sedrati, Mouncef.
The Guadiana estuary is a coastal system located in the southwest of the Iberian Peninsula and is the natural border between Portugal and Spain. It is a rock-bounded estuary which extends along more than 40 km and is characterized by a semidiurnal mesotidal regime. This paper represents an approach to the bedload transport across two flow sections located in the fluvial and marine domains. In the fluvial profile, the most frequent bedform is the plane bed. In the marine area the bed of the deep channel is composed of well-sorted sand, while a lateral bar displays partially cohesive sediments with dominant fine sands in a matrix of clayey silts. Data were acquired during spring and neap tides. Near-bottom water velocities were registered by an acoustic...

Calibration of complex, process-based ecosystem models is a timely task with modellers challenged by many parameters, multiple outputs of interest and often a scarcity of empirical data. Incorrect calibration can lead to unrealistic ecological and socio-economic predictions with the modeller’s experience and available knowledge of the modelled system largely determining the success of model calibration. Here we provide an overview of best practices when calibrating an Atlantis marine ecosystem model, a widely adopted framework that includes the parameters and processes comprised in many different ecosystem models. We highlight the importance of understanding the model structure and data sources of the modelled system. We then focus on several model outputs...

The use of empirical agrometeorological models that can be adjusted to the climatic conditions of different regions has become increasingly necessary to improve water management in grain-producing municipalities. The aim of this work is to examine the correlation between various reference evapotranspiration (ETo) estimation methods and the standard FAO 56 Penman-Monteith method, as well as to determine correction factors, when necessary, for crop-producing municipalities in the northeast of Pará, during both the rainy and dry seasons. We compared simpler methods of ETo estimation to the FAO 56 Penman-Monteith method. For this purpose, meteorological data from Tracuateua, Bragança, Capitão Poço and Castanhal, provided by the National Institute of...

Calibration of the Normalized Radar Cross Section for Sentinel-1 Wave Mode
Provedor de dados: 5
Autores: Li, Huimin; Mouche, Alexis; Stopa, Justin E.; Chapron, Bertrand.
Sentinel-1 (S-1) is a two-satellite constellation for continuity of operational synthetic aperture radar (SAR) observations. Wave mode (WV) is the default mode over open ocean for S-1 to monitor global ocean waves and wind field. Therefore, proper radiometric calibration is essential to accurately infer these geophysical quantities. Based on the global data set acquired by S-1A WV, assessment of normalized radar cross section (NRCS) is carried out through comparison with CMOD5.N predictions over open ocean. The calibration accuracy quantified by NRCS residuals between SAR measurements and CMOD5.N demonstrates distinct features for two incidence angles (23.8° and 36.8°). Particularly, NRCS at 23.8° is overall consistent with CMOD5.N, while NRCS at 36.8°...

An uneven distribution of maize plants at the sowing row can decrease grain yield. This work was carried out to evaluate the effect of an increasing nitrogen rate on maize agronomic performance under different variation coefficients of plant spatial distributions at the sowing row. The experiment was conducted in Lages, Santa Catarina State, South Brazil. Three variation coefficients (VC) of plant spatial distribution (0, 50, and 100%) were tested. At the 0 level, seeds were evenly distributed 17 cm from each other. In the other treatments with uneven spatial distributions, the distances between two neighbouring seeds ranged from 2 to 54 cm. Four nitrogen side-dress rates (0, 125, 250, and 375 kgN ha-1) were evaluated. The increase in VC of plant spatial...

ABSTRACT The aim of this work was to determine whether socioeconomic factors explain the importance of culturally salient plants to social-ecological systems. Extractive communities of the Araripe-Apodi Environmental Protection Area in Northeast Brazil were studied, and a random sample of the population was selected. Quantitative variables (education, age and income) were analyzed using Spearman correlations, while categorical variables (gender and occupation) were analyzed using Mann-Whitney tests. Relationships between socioeconomic factors and the importance of culturally salient plants were all weak. Nevertheless, age influenced the local importance of the largest number of species. Other factors not considered in this study (historical, cultural,...

Can strip-cropping enhance pollination and fruit set in Hokkaido pumpkins?
Provedor de dados: 21
Autores: Johansen, Natasha H.; Dupont, Y.L.
The demand for organic vegetables is increasing rapidly but cannot be met by current agronomic methods. Alternative methods, which enhance biodiversity and ecosystem services including pollination, are currently under development. In SureVeg (a Core Organic Co-fund funded project), we tested strip-cropping systems, i.e. a diversified cropping system in which alternating rows of different vegetable crops are sown. It is hypothesized that strip-cropping will provide floral resources during an extended period, supporting agroecosystem services provided by beneficial insects, including natural biological control and insect pollination.  In the current study, we investigated a cropping system involving two insect pollinated crops: hokkaido pumpkin and faba...

ABSTRACT:  Progressive deterioration and loss of articular cartilage are the final degenerative events common to osteoarthritis (OA). Reactive oxygen species (ROS) play an important role in this chondrocyte catabolic activity, leading to cell death and matrix components breakdown. Intra-articular corticosteroid injections such as triamcinolone acetonide have been used to control pain and inflammation associated with OA. New treatments for OA, platelet-rich plasma and pentosan polysulphate sodium have also been used and further investigations are necessary to determine their safety in joint cells. In this in vitro study, the use of these three substances (triamcinolone acetonide, platelet-rich plasma, and pentosan polysulphate sodium) in healthy...

Can we generate robust species distribution models at the scale of the Southern Ocean?
Provedor de dados: 5
Autores: Fabri-ruiz, Salomé; Danis, Bruno; David, Bruno; Saucède, Thomas.
Aim Species distribution modelling (SDM) represents a valuable alternative to predict species distribution over vast and remote areas of the ocean. We tested whether reliable SDMs can be generated for benthic marine organisms at the scale of the Southern Ocean. We aimed at identifying the main large‐scale factors that determine the distribution of the selected species. The robustness of SDMs was tested with regards to sampling effort, species niche width and biogeography. Location Southern Ocean. Methods The impact of sampling effort was tested using two sets of data: one set with all presence‐only data available until 2005, and a second set using all data available until 2015 including recent records from campaigns carried out during the Census of...

Abstract: Besides stimulating vasoconstriction, Angiotensin II is also well known in inducing reactive oxygen species and promoting inflammatory phenotype switch via its type 1 receptor. In clinic, Angiotensin II type 1 (AT1) receptor blocker like candesartan has been widely applied as an antihypertensive medication. We previous have demonstrated that a higher dose of candesartan plays a protective role after kidney injury. However, whether candesartan could exhibit anti-inflammatory effects remains unclear. Here, by stimulating isolated human embryonic kidney epithelial cells with tumor necrosis factor-α (TNF-α), we observed the anti-inflammation capacity of candesartan ex vivo. It was found that pre-treat with candesartan significantly suppressed...

Autores: PINTO,ANA CAROLINA C.; ROCHA,DEBORA A.S.; MORAES,DANIEL C. DE; JUNQUEIRA,MARIA L.; FERREIRA-PEREIRA,ANTONIO.
Abstract: ﻿Candida albicans is the most frequent fungal species that causes infections in humans. Fluconazole is the main antifungal used to treat Candida infections, and its prolonged and indiscriminate use for the last decades are the most established causes which originated resistant strains. Fungal drug resistance is associated to alterations in ERG11 gene and overexpression of multidrug resistance (MDR) transporters belonging to two families: ATP-binding cassette (ABC) and Major Facilitator Superfamily (MFS). To evaluate the role of MFS transporters in azoles resistance of C. albicans clinical strains, this study aimed to analyze four Candida albicans clinical isolates from the University Hospital in Juiz de Fora (Minas Gerais/Brazil), selected in our...

Autores: Alonso,F.H.; Bulla,C.; Paes,P.R.O.
ABSTRACT The objective of this study was to determine the frequency of different categories of specific and general classification in canine cavitary effusions (CE), as well as their association with the underlying etiologies. The laboratorial and clinical data from 304 cases of canine CE were retrospectively assessed. In 32.9% (100 cases), at least one of the specific classification categories was established, with a subtotal predominance of neoplasia (42%), bacterial serositis (24%) and hemorrhage (16%). Neoplasia was confirmed by effusion cytology in 57.5% of the cases with histopathological confirmation. From the cases in which the specific classification was not obtained, 35.8% were classified as modified transudate, 30.4% as pure transudate, 21.1% %...

The Mediterranean Sea is one of the main hotspots of marine biodiversity in the world. The combined pressures of fishing activity and climate change have also made it a hotspot of global change amidst increasing concern about the worsening status of exploited marine species. To anticipate the impacts of global changes in the Mediterranean Sea, more integrated modelling approaches are needed, which can then help policymakers prioritize management actions and formulate strategies to mitigate impacts and adapt to changes. The aim of this study was to develop a holistic model of marine biodiversity in the Mediterranean Sea with an explicit representation of the spatial, multispecies dynamics of exploited resources subject to the combined influence of climate...

Caractérisation expérimentale et numérique du comportement hydrodynamique d’une hydrolienne à membrane ondulante
Provedor de dados: 5
Autores: Trasch, Martin.
The thesis presented in this document deals with the caracterisation of the behaviour of an undulating membrane tidal energy converter. This kind of device uses the flutter instabilities occurring between a semi-rigid pre-strained membrane and a fluid flow in order to convert the sea currents energy. Above a certain critical flow speed, the structure ondulates, thus activating the linear converters fixed on it. In order to study this system, an experimental model is developped and tested in a flume tank. The power conversion system is simulated by hydraulic dampers. The membrane’s dynamics is analysed in many configurations through trajectory and force measurements, and leads to a parametric study. More realistic flow conditions are also studied, such as...

Carbohydrate antigen 125 (CA125) has long been used as an ovarian cancer biomarker. However, because it is not specific for ovarian cells, CA125 could also be used to monitor congestion and inflammation in heart disease. Acute heart failure (HF) is used to identify patients with a worse prognosis in ST-segment elevation myocardial infarction (STEMI). We aimed to determine the association of CA125 with acute HF in STEMI and to compare CA125 with N-terminal pro brain natriuretic peptide (NTproBNP) with a cross-sectional study. At admission, patients were examined to define Killip class and then underwent coronary angioplasty. Blood samples, preferably taken in the hemodynamic ward, were centrifuged (1500 g for 15 min at ambient temperature) and stored at...

Carbon and silicon cycles at the Earth surface are linked to long-term variations of atmospheric CO2 and oceanic primary production. In these cycles, the river-sea interface is considered a biogeochemical hotspot, and deltas presently receive and preserve a major fraction of riverine particles in shallow water sediments. In contrast, periods of glacial maximum lowstand were characterized by massive exports of sediments to the deep-sea via submarine canyons and accumulation in deep-sea fans. Here, we calculate present-day mass balances for organic carbon (OC) and amorphous silica (aSi) in the terminal lobe complex of the Congo River deep-sea fan as an analogue for glacial periods. We show that this lobe complex constitutes a megasink with the current...

Carbon Dynamics Along the Seine River Network: Insight From a Coupled Estuarine/River Modeling Approach
Provedor de dados: 5
Autores: Laruelle, Goulven G.; Marescaux, Audrey; Le Gendre, Romain; Garnier, Josette; Rabouille, Christophe; Thieu, Vincent.
The Seine river discharges over 700 Gg of carbon (C) every year into the sea mostly under the form of dissolved inorganic carbon (DIC) and emits 445 Gg under the form of carbon dioxide (CO2) to the atmosphere over its entire river network. The watershed, which drains 76,000 km2, is heavily populated with 18 106 inhabitants and is thus submitted to large anthropic pressure. The offline coupling of two Reactive Transport Models is used to understand the complex spatial and temporal dynamics of carbon, oxygen and nutrients and quantify the CO2 exchange at the air-water interface along the main axis of the river. The estuarine section of the Seine is simulated by the generic estuarine model C-GEM (for Carbon Generic Estuarine Model), while the upstream part of...

Autores: Corrêa,Juliano Corulli; Ródio,Lauri Caetano; Rigo,Amanda Zolet; Grohskopf,Marco André; Rebellatto,Agostinho; Mafra,Álvaro Luiz.
Abstract: The objective of this work was to evaluate the effect of the application of organomineral and mineral fertilizers to highly fertile soils on the carbon management index (CMI) and carbon fractions and stock. The experiment was carried out on an Oxisol and Inceptisol, under no-tillage, in three crop seasons. The treatments consisted of two organomineral fertilizers and of two mineral fertilizers in solid and fluid forms, besides a control without fertilization. The application of organomineral and mineral fertilizers, in solid and fluid forms, to the different soil classes with high fertility promoted changes in total organic carbon, particulate organic carbon, and carbon associated with minerals, as well as in carbon stocks and the CMI. In the...

Carbon indices to assess quality of management systems in a Subtropical Acrisol
Provedor de dados: 63
Autores: Zanatta,Josiléia Acordi; Vieira,Frederico Costa Beber; Briedis,Clever; Dieckow,Jeferson; Bayer,Cimélio.
ABSTRACT: Management systems to improve soil quality are essential for agricultural and environmental sustainability. We assessed the quality of soil management systems applied to a subtropical Acrisol in terms of the carbon management index (CMI), the stratification ratio for total organic carbon (SR-TOC) and light fraction of organic matter (SR-LF). In addition, we examined their relationship to chemical, physical and biological soil quality indicators, as well as to maize yield. The study was conducted on a long-term experiment (18 years) in southern Brazil involving two different systems [no tillage (NT) and conventional tillage (CT)], two cropping systems [black oat/maize (O/M) and black oat + vetch/maize + cowpea (OV/MC)] and two nitrogen fertilizer...

Diatoms adapt to changing environmental conditions in very efficient ways. Among the mechanisms that can be activated, the reorientation of carbon metabolism is crucial because it allows the storage of energy into energy-dense molecules, typically lipids. Beside their roles in physiology, lipids are commercially interesting compounds. Therefore studies dealing with this topic are relevant for both basic and applied science. Although the molecular mechanisms involved in the reorientation of carbon metabolism as a response to a deficiency in nutrients such as nitrogen or phosphorus has been partially elucidated, the impacts of carbon availability on the implementation of the reorientation mechanisms remain unclear. Indeed, it has not been determined if the...

Carbon/polyamide 6 thermoplastic composite cylinders for deep sea applications
Provedor de dados: 5
Autores: Arhant, Mael; Briancon, Christophe; Burtin, Christian; Davies, Peter.
The composite materials used at sea are today nearly all based on thermoset resins (polyester, epoxy). However, there is an increasing number of thermoplastic matrix polymers available on the market (PP, PA, PPS, PEEK…), which offer possibilities for forming by local heating, attractive mechanical properties and the potential for end of life recycling. The aim of this study was to design, manufacture and test thermoplastic composite pressure vessels for 4500 meter depth, in order to establish a technical, economic and ecological assessment of the use of these materials to replace traditional composites underwater. First, finite element calculations have been carried out to optimize the stacking sequence with respect to the external pressure and buckling...

Acetaldehyde and formaldehyde may be formed through the ethanol and methanol oxidation, respectively. Acrolein may arise as a thermal degradation product of glycerol, amino acids, carbohydrates and triglycerides or by metabolic activity of microorganisms. In addition, acrolein and furfural are formed during wood combustion; therefore, these aldehydes may be present in raw materials due to the environmental contamination. Furfural is also a product of the Maillard reaction formed from sugars and amino acids, while ethyl...

Autores: Zepeda-Bastida,Armando; Martínez,Maricela Ayala; Simental,Sergio Soto.
ABSTRACT The objective of this study was to use different parts of the Tithonia tubaeformis plant in feed for fattening rabbits and then observe the effects on carcass and meat quality. Forty-eight weaned rabbits (35 days of age) were randomly assigned to four groups (n = 12 by treatment). Animals were fed ad libitum a control diet as well as three experimental diets, with addition of Tithonia tubaeformis leaves, whole plant, and stems. Rabbits were slaughtered after 63 days of age without fasting. Results indicate that live weight (0.917), skin (0.79), feet (6.679), and lumbar circumference of the carcass (0.707) have higher positive correlations with hot carcass. There were no significant differences between treatments for all variables measured, except...

Autores: Rezende, Pedro Leonardo de Paula; Restle, João; Bilego, Ubirajara Oliveira; Fernandes, Juliano José de Resende; Missio, Regis Luis; Guimarães, Tiago Pereira.
Carcass and meat characteristics of 48 Nellore heifers at 24 to 30 months of age, with an initial weight of 263.4 ± 13.9 kg, were evaluated. The experiment was set up as a completely randomized design with four treatments, which consisted of four slaughter-weight classes, namely &lt;340, 340-370, 370-400, or &gt;400 kg. Back fat thickness was not influenced (p &gt; 0.05) by slaughter weight in any of the forms it was expressed (mm or %), averaging 5.3 mm. Loin eye area in cm2 increased (p &lt; 0.05) with the increase in slaughter weight. Animals slaughtered at a live weight (LW) of more than 400 kg showed better (p &lt; 0.05) carcass conformation than the other experimental groups (9.8 points). Heifers slaughtered at over 400 kg LW had a more compact (p...

Cardiac function and intracellular Ca2+ handling proteins are not impaired by high-saturated-fat diet-induced obesity
Provedor de dados: 56
Autores: Deus,A.F.; Vileigas,D.F.; Silva,D.C.T.; Tomasi,L.C.; Campos,D.H.S.; Okoshi,K.; Padovani,C.R.; Cicogna,A.C.
Obesity is often associated with changes in cardiac function; however, the mechanisms responsible for functional abnormalities have not yet been fully clarified. Considering the lack of information regarding high-saturated-fat diet-induced obesity, heart function, and the proteins involved in myocardial calcium (Ca2+) handling, the aim of this study was to test the hypothesis that this dietary model of obesity leads to cardiac dysfunction resulting from alterations in the regulatory proteins of intracellular Ca2+ homeostasis. Male Wistar rats were distributed into two groups: control (C, n=18; standard diet) and obese (Ob, n=19; high-saturated-fat diet), which were fed for 33 weeks. Cardiac structure and function were evaluated using echocardiographic and...

ABSTRACT Aiming to provide cardiovascular morphophysiology information on the Cuniculus paca, an important neotropical rodent, eight healthy adult females of this species were evaluated three times by echocardiography under general anesthesia with isoflurane every 15 days. The exams were performed by a single experienced evaluator with the animals positioned in right and left decubitus. Posteriorly, two expert evaluators measured the cardiac chambers, walls and flow patterns, by B-mode, M-mode, and Doppler ultrasonography. The resulting values were compared among evaluators and periods by the Bland-Altman agreement test and several descriptive statistics were presented for each parameter. Echocardiographic images were obtained between the second and fifth...

ABSTRACT The slow darkening of grains is sought by bean breeders because the consumers consider that darker grains demand more time for cooking. The analysis currently used takes around 90 days to differentiate grain color among genotypes. The objective was to evaluate the color as a function of the value of L* (lightness) of carioca beans, by natural and accelerated methods to verify equivalence between methods, validation of the methodology and identification of genotypes tolerant to the darkening. The grain darkening was compared and evaluated by natural darkening method under shelf conditions, in days storage, and accelerated darkening method under ultraviolet light, in hours. The natural darkening time of 90 days was statistically equal to 24 hours of...

Provedor de dados: 56
Autores: Zhang,Mei; Wen,Xiaorong; Zhou,Chenyun; Huang,Jing; He,Ying.
Peripheral arterial disease (PAD) can impair healing of diabetic foot (DF) in patients with diabetes mellitus. To determine whether carotid intima-media thickness (CIMT) can predict lower limb arterial lesions in patients with DF, this cross-sectional study enrolled patients with DF at West China Hospital (China) between January 2012 and December 2015. Ultrasonography was used to measure CIMT, assess the internal carotid arteries (ICA) for plaques, and evaluate lower limb segmental arteries for stenosis. The optimal CIMT cutoff for detecting lower limb PAD was determined by receiver operating characteristic (ROC) curve analysis. Factors associated with PAD were identified by logistic regression analyses. A total of 167 patients (mean age: 69.7±10.3 years;...

Carriage prevalence of Neisseria meningitidis in the Americas in the 21st century: a systematic review
Provedor de dados: 55
Autores: Santos-Neto,José Francisco; Ferreira,Viviane Matos; Feitosa,Caroline Alves; Martinez-Silveira,Martha Silvia; Campos,Leila Carvalho.
Abstract Neisseria meningitidis is a bacterium that colonizes the human nasopharynx and is transmitted by respiratory droplets from asymptomatic or symptomatic carriers. Occasionally, the pathogen invades the mucosa and enters the bloodstream, causing invasive meningococcal disease, a life-threatening infection. While meningococcal colonization is the first step in the development of invasive disease, the risk factors that predict progression from asymptomatic to symptomatic status are not well-known. The present report aimed to describe the prevalence of N. meningitidis carriers throughout the Americas, emphasizing the risk factors associated with carrier status, as well as the most prevalent serogroups in each studied population. We conducted a...

Abstract  The cashew tree, a genuinely Brazilian fruit tree, is grown mainly because of its nuts and cashew nut shell liquid (CNSL), widely used in industry. Of great food importance, the cashew apple also presents economic representativeness in Brazil. With great variability, the culture has recently begun researches for improvement, with selection of new clones, more productive and with specific purpose. Usually propagated from seeds to produce new orchards, which has been replaced by vegetative propagation using the seed only for rootstocks production. Vegetative propagation by lateral grafting is the mainly technique used to multiplicated this crop, but various clonal propagation techniques, such air layering and tissue culture have been attempted.

Uma alternativa para o produtor de leite está em incorporar as áreas de pastagens aos sistemas de produção, de forma planejada. Isso significa aumentar não só a oferta de alimentos nobres, como leite, carne e cereais, mas produzir múltiplos produtos de florestas plantadas, como madeira, energia, fibra e biodiesel. Neste sentido, os sistemas de integração lavoura-pecuária-floresta (ILPF) ganham destaque como uma alternativa de produção sustentável para a agricultura familiar em áreas montanhosas, na medida em que proporcionam a otimização do uso do solo com ganhos ambientais, aumento da produtividade e da renda no meio rural.

Castanha-do-brasil: boas práticas na coleta e pós-coleta da castanha-do-brasil em Mato Grosso.
Provedor de dados: 14
Autores: BOTELHO, S. de C. C.
A castanha-do-brasil, também conhecida como castanha-do-pará ou castanha-da-amazônia, é uma amêndoa coletada da castanheira. Os frutos são conhecidos como ouriços, podem pesar até 1,5 kg e conter, aproximadamente, 25 sementes ricas em vitaminas, lipídios e proteínas. A safra da castanha ocorre anualmente, durante o período chuvoso (outubro a abril), quando se dá a queda dos frutos. O contato dos frutos com o solo e a presença de umidade contribuem para a contaminação por fungos produtores de micotoxinas indesejadas nas castanhas. Entre essas toxinas, a aflatoxina é a mais comum e seu consumo pode causar diversos problemas de saúde, entre eles o câncer.

ABSTRACT:  This study characterized the demography and spatial pattern of a yerba mate (Ilex paraguariensis A.St.-Hil) population covering areas with different use histories (Presence and Absence of Cattle) in a Araucaria Forest. Data collection was performed in three ha, half in each area. The frequency of individuals by height, spatial distribution pattern, diameter distribution (for reproductive individuals) and sexual ratio were evaluated. An inverted “J” pattern predominated, being exclusive to an area with Cattle Presence, a place which presented a lower density of individuals. The predominant spatial distribution pattern was aggregated, and the reproductive individuals have a preferentially random pattern at the shortest distances. Results indicated...

Autores: HIRATA,A.C.S.; HIRATA,E.K.; RÓS,A.B.; NARITA,N.
ABSTRACT: In vegetable farming, the reduction in the use of herbicides has been an important factor in the definition of the production system. The objective of this research was to evaluate crop yield of cauliflower cultivars grown on Urochloa decumbens straw mulch, as well as the effect of the association between straw and cultivars on weed management. The treatments were arranged in a 2 x 4 factorial scheme: two managements (with or without U. decumbens straw mulch) and four cauliflower cultivars (Barcelona, Bromus, Júlia and Lisblanc). The experiment used a randomized block design with four replicates. There was no interference of straw mulch on crop yield of cauliflower cultivars. Hybrids Barcelona and Júlia presented yields of 22.0 and 23.9 t ha-1,...

CCAAT/enhancer-binding protein alpha (CEBPA) gene haploinsufficiency does not alter hematopoiesis or induce leukemia in Lck-CALM/AF10 transgenic mice
Provedor de dados: 56
Autores: Lange,A.P.; Almeida,L.Y.; Araújo Silva,C.L.; Scheucher,P.S.; Chahud,F.; Krause,A.; Bohlander,S.K.; Rego,E.M.
Although rare, CALM/AF10 is a chromosomal rearrangement found in immature T-cell acute lymphoblastic leukemia (T-ALL), acute myeloid leukemia, and mixed phenotype acute leukemia of T/myeloid lineages with poor prognosis. Moreover, this translocation is detected in 50% of T-ALL patients with gamma/delta T cell receptor rearrangement, frequently associated with low expression of transcription factor CCAAT/enhancer-binding protein alpha (CEBPA). However, the relevance of CEBPA low expression for CALM/AF10 leukemogenesis has not yet been evaluated. We generated double mutant mice, which express the Lck-CALM/AF10 fusion gene and are haploinsufficient for the Cebpa gene. To characterize the hematopoiesis, we quantified hematopoietic stem cells, myeloid...

CD47 expression is decreased in hematopoietic progenitor cells in patients with myelofibrosis
Provedor de dados: 56
Autores: Nonino,A.; Nascimento,J.M.; Mascarenhas,C.C.; Mazzeu,J.F.; Pereira,R.W.; Jacomo,R.H.
Myelofibrosis (MF) is characterized by increased circulating hematopoietic progenitor cells (HPCs), abnormal cytokine levels, and the survival advantage of neoplastic progenitors over their normal counterparts, which leads to progressive disappearance of polyclonal hematopoiesis. CD47 is a surface glycoprotein with many functions, such as acting as a phagocytosis inhibitor of the expressing cell, that is increased in normal hematopoietic stem and progenitor cells mobilized into the blood and several human cancer-initiating cells, such as in acute myeloid leukemia. We compared CD47 expression in hematopoietic stem and progenitor cells of patients with MF and controls and found it to be decreased in progenitors of MF. Exposure of control HPCs to the...

ABSTRACT Hepatitis E virus (HEV) is considered one of the leading causes of acute viral hepatitis worldwide, and about 20 million infections and approximately 57 000 deaths occurred every year. However, little is known about the replicative virus cycle due to the absence of a consensus cell culture model. A549 cell line is considered susceptible to HEV genotype 3, however, both viral strain and cell culture conditions could affect the viral isolation in vitro. The objective of this work was to isolate in vitro an HEV-3 strain obtained from human feces. To this, a genotype 3 HEV strain previously identified by genetic characterization was inoculated in A549 monolayers, and incubated for two hours at 37 °C. Five days post-infection, cells were passaged...

ABSTRACT A 15-year-old, mixed breed, male horse was attended with a history of multiple abscesses in the cervical region with a three-year evolution. Upon admission, three fistulous tracts with drainage of purulent secretions in the cervical region, low body score, restriction of cervical movements, and painful sensitivity to palpation were observed. The horse was diagnosed with osteomyelitis secondary to Streptococcus equi infection. The initial treatment was antibiotic therapy and local curative. Owing to the lack of response, surgical debridement was performed. An initial favorable response was observed; however, after 4 months, drainage recurred, and the animal was euthanized. A post-mortem computed tomography scan was performed to obtain details of...

CFD and experimental analysis of direct solar dryer for fish
Provedor de dados: 111
Autores: Obayopo, Surajudeen Olanrewaju; Oluwasanmi, Alonge.
 Fish preservation is the most important post-harvest process in commercial fishery. The traditional methods of fish preservation are inefficient and susceptible to contamination. Few existing solar fish dryers are not designed for optimal drying performance. In this study, a direct solar dryer for fish was numerically modelled, fabricated and evaluated for performance enhancement. The modeling was performed using computational fluid dynamics (CFD) code to simulate different dimensions of the designed dryer at varying fan speeds. By applying desirability function method, (70 × 60 × 40) cm3 drying chamber with a plane of 25 cm away from the base for tray location gives optimal temperature and the best uniform air flow distribution. The performance of the...

We revisit the challenges and prospects for ocean circulation models following Griffies et al. (2010). Over the past decade, ocean circulation models evolved through improved understanding, numerics, spatial discretization, grid configurations, parameterizations, data assimilation, environmental monitoring, and process-level observations and modeling. Important large scale applications over the last decade are simulations of the Southern Ocean, the Meridional Overturning Circulation and its variability, and regional sea level change. Submesoscale variability is now routinely resolved in process models and permitted in a few global models, and submesoscale effects are parameterized in most global models. The scales where nonhydrostatic effects become...

Visceral leishmaniasis is a zoonotic disease caused by the protozoa of the mononuclear phagocyte system, having dogs as its main urban host. Clinical diagnosis is difficult to perform because of the diversity of clinical signs and the occurrence of asymptomatic cases. Thus, the disease is confirmed by employing laboratory methods. This study reports a case of canine visceral leishmaniasis in which the patient presented several clinical signs, and the veterinarian’s knowledge about the disease was necessary to establish the correct diagnosis.

Changements climatiques dans la mer de Barents : interactions glace-océan, formation et variabilité de la masse d'eau
Provedor de dados: 5
Autores: Barton, Benjamin I.
Winter sea ice has declined in the Barents Sea and there is growing evidence that the low sea ice here coincides with cold, winter surface air temperature in Europe and Asia. Atlantic Water (AW) transported into the Barents Sea is warming and its temperature variability is correlated with variability in sea ice extent. As AW extends into the Barents Sea it is modified into a cooler, fresher water mass called BarentsSea Water (BSW). There are limited observations of BSW despite its importance in the Arctic Ocean system, leading to the question, how does the seasonal sea ice impact ocean stratification and mean flow?First, satellite observations are used to find the Polar Front, a water mass boundary between BSW and fresher Arctic Water to the north. The sea...

Autores: Frías-Quintana,Carlos Alfonso; Álvarez-González,Carlos Alfonso; Guerrero-Zárate,Rocío; Valverde-Chavarría,Silvia; Ulloa-Rojas,Juan B.
ABSTRACT Wolf cichlid, Parachromis dovii, is a species with a high potential for aquaculture in Central America; however, the knowledge of the digestive physiology in larvae period is limited. For these reason, this study evaluated the changes on digestive enzymes (alkaline and acid proteases, trypsin, chymotrypsin, aminopeptidase, carboxypeptidase, lipases, amylases, and phosphatases) during early ontogeny by biochemical analysis. All digestive enzymes were detected at first feeding (6 days after hatching, DAH, 9.49 mm, 168 degree-days DD). Afterwards all enzymes reached two main peaks in activity at 14 or 22 DAH (15.10 mm, 364 DD and 20.83 mm, 550 DD, respectively). Later, there was a gradual decrease in activity for trypsin and acid and alkaline...

Among the species cultivated in Mato Grosso do Sul, the area with soybeans is larger than that only for pasture cultivation. This work was developed in fourteen municipalities of the state. Based on information from the Brazilian Institute of Geography and Statistics (IBGE), the evolution of the area occupied by soybean, pasture and sugarcane in these municipalities was analysed. In particular, the area cultivated with soybeans has shown constant and significant growth. On the other hand, the pasture area has been continuously decreasing, especially in Ponta Porã, Maracaju and Rio Brilhante. The areas previously occupied with pastures are giving way to soy and sugarcane cultivation.

Abstract  Changes in the accumulation patterns of mineral nutrients at different development stages of fruit reflect the requirements of citrus trees for different nutrients, and this information provides an essential reference for rational fertilization. In this study, changes in the contents of 11 nutrients in the whole fruit, fruit pulp, and peel were studied during the whole developmental period of the fruit of ‘Seike’ and ‘Newhall’ navel oranges. We found that the two navel orange cultivars showed very similar changes in nutrients. Specifically, the N, P, Mg, S, Mn, and Zn contents were high in the young fruit stage (April), the K and Fe contents were high in the fruit expansion stage (July and August), and the Ca content was high in the fruit...

ABSTRACT The aim of this study was to evaluate the changes in osmoregulatory metabolism of cotton genotypes subjected to water deficit and recovery period. In a greenhouse, six cotton genotypes and two water managements were combined in a 6 x 2 factorial scheme, in a completely randomized design, evaluated after 14 and 22 days under water stress and recovery conditions, respectively. The water status, growth indicators and compatible solutes in the leaves were evaluated. The genotypes BRS Seridó, BRS Aroeira and BRS 7MH withstand better the stress condition because they had lower variations in their water potentials due to the osmotic adjustment and maintained their growth under water deficit conditions. The BRS 286 is the most sensitive genotype to the...

Oysters modify the planktonic microbial community structure by their filtration and NH4 excretion activities. While many studies have been conducted on this subject with adult oysters, none had been carried out in situ with juveniles. Pacific oyster juveniles (Magallana gigas, previously Crassostrea gigas) died massively all over the world since 2008 in relation with OsHV-1 infection. During mortality episodes, sick and dead oysters are not separated from healthy live ones, and left to decay in the surrounding environment, with unknown consequences for the nutrient cycle and planktonic microbial components (PMC). The present study aimed to elucidate for the first time the interactions between oyster juveniles and PMC during a mortality episode. Innovative...

Autores: Santos, Mirelle Nayana de Sousa; Araujo, Fernanda Ferreira de; Lima, Paula Cristina Carvalho; Costa, Lucas Cavalcante da; Finger, Fernando Luiz.
The increased demand for potato by the Brazilian processing industry requires long term refrigerated storage, but after a few months, natural dormancy ends, and sprouts start to grow. Thus, sprout inhibitors are necessary to reduce the rate of growth and allow further storage. The purpose of research described here was to determine the effects clove and menthol essential oils have on the inhibition of sprout growth in non-dormant ‘Asterix’ tubers. Both eugenol and menthol treatments reduced the rate of sprout growth during storage at 8oC for up to 50 days. Eugenol and menthol essential oils diminished the rate of accumulation of reducing sugar, which are responsible for browning of French fries. Color after frying was within acceptable levels when the...

Autores: Silva,Pollyane Vieira da; Savian,Taciana Villela.
ABSTRACT:  The growth of plants and animals can be described through a growth curve. This curve is given by the equation of a nonlinear model, such as the Logistic model and the Gompertz model. The objective of this study was to adjust the Chanter model, as well as Logistic and Gompertz, using a set of cocoa (clone Sial-105) fruit whose length and diameter measurements were evaluated from 30 to 180 days after pollination, every 15 days. The Chanter model is a hybrid between the Logistic model and Gompertz model whose parameters can be interpreted similarly. A comparison of the quality of fit between the models was made using the following statistical measures: the Akaike’s information criterion (AIC), the Akaike’s weights criterion, Bayesian information...

The Sea Surface Microlayer (SML) is known to be enriched in trace metals relative to the underlaying water and to harbor diverse microbial communities (i.e. neuston). However, the processes linking metals and biota in the SML are not yet fully understood. In this study, we analyzed the metal (Cd, Co, Cu, Fe, Ni, Mo, V, Zn and Pb) concentrations in aerosol samples, SML (dissolved and total fractions) and in subsurface waters (SSW; dissolved fraction at ~ 1 m depth) from the Western Mediterranean Sea during a cruise in May–June 2017. The bacterial community composition and abundance in the SML and SSW, and the primary production and Chl-a in the SSW were measured simultaneously at all stations during the cruise.

Abstract Accurate and rapid diagnostic tools are important aspects of managing tuberculosis (TB) cases appropriately. However, the sensitivity and specificity of diagnostic kits based on immune response such as the tuberculin skin test (TST) and interferon gamma release assay (IGRA) are still debated. Thus, the exploration and assessment of specific biomarker-targeted antibodies are needed for the development of an accurate and rapid diagnostic tool. The present study was conducted in patients with a respiratory problem suspected to be TB at Dr. Soetomo Hospital, Surabaya, Indonesia. Among 102 patients tested by GeneXpert and AFB, 59 serum samples were from cases retrospectively determined to have active TB. A total of 102 serum of healthy controls (HC)...

Abstract The present study consists of the in situ characterization and selection of minimal morphoagronomic descriptors in Passiflora cincinnata genotypes. Forty-one quantitative morphoagronomic descriptors were used, divided in “Plant and Leaf”, “Floral” and “Fruit”. Principal component analysis were used to eliminate descriptors that were less important in the study of multivariate dissimilarity among genotypes. The formation of groups was carried out using Ward’s hierarchical grouping method. The importance of the characters was estimated through the participation of the components by Singh’s method (1981) in order to verify the similarity between lower participation variables in the components. For the set of descriptors “Plant and Leaf” the...

Autores: Drain, Alice; Bonneau, Laurent; Recorbet, Ghislaine; van Tuinen, Diederik; Wipf, Daniel; Courty, Pierre-Emmanuel.
We developed a new protocol to study arbuscular mycorrhizal fungal (AMF) communities in Bordeaux vineyards in a standardized way, in order to compare results obtained over years and between locations. To this end, we first used grapevine root samples instead of soil samples to avoid AMF spores or hyphae interacting with cover plants. We next increased the number of grapevine samples to obtain more representative coverage of AMF communities while decreasing variability intra-vineyard, especially for the larger parcels. In addition, we adapted the DNA extraction protocol dedicated to soil samples to grapevine roots, as a way to increase the yield and the purity of samples. These features, coupled to the choice of the LSU-D2 region as the molecular marker for...

ABSTRACT Capsicum baccatum is one of the main chili pepper species grown and consumed in South America. In Brazil, C. baccatum var. pendulum is widely cultivated, especially “dedo-de-moça” type. For most horticultural crops, including Capsicum species their diversity remains under-explored for traits related to fruit quality, since over the past half century breeding efforts have focused mainly on good agronomic performances. The investment in screening traits such as flavor, nutritional compounds and antioxidant content in traditional varieties is very important to support fruit quality breeding efforts. Thus, the objective of this study was accessing the variations into content of soluble solid, acidity, capsaicinoid, vitamin C, total phenolic compounds...

In the marine environment, biofilm formation is an important lifestyle for microorganisms. A biofilm is comprised of cells embedded in an extracellular matrix that holds them close together and keeps the biofilm attached to the colonized surface. This predominant lifestyle and its main regulation pathway, namely quorum-sensing (QS), have been shown to induce specific bioactive metabolites. In this study, we investigated the biofilm formation by two marine bacteria belonging to the Vibrio species to discover potentially innovative bioactive compounds. We proposed a protocol to isolate biofilm extracts, to analyze their biochemical composition, and to compare them to planktonic cell extracts. Cells were grown attached to a plastic surface; extracts were...

Autores: Paula,Ailton Ferreira de; Dinato,Naiana Barbosa; Vigna,Bianca Baccili Zanotto; Fávero,Alessandra Pereira.
ABSTRACT In Brazil, the thrips (Enneothrips flavens Moulton) and rednecked peanutworm (Stegasta bosquella Chambers) are considered key pests for the peanut crop. Wild species show resistance to both of these pests, and can be used in breeding programs. The production of the sterile interspecific hybrids is necessary, which could be colchicine treated to get a synthetic amphidiploid with the same or similar genomic configuration of cultivated peanut. In this context, this study proposed the hybridization of wild pest-resistant species in 18 distinct combinations, obtaining the interspecific hybrids of Arachis and completing their characterization by (i) the reproductive characterization through pollen stainability with 2% acetocarmine (AC) solution with...

Bacteria from deep-sea hydrothermal vents constitute an attractive source of bioactive molecules. In particular, exopolysaccharides (EPS) produced by these bacteria become a renewable source of both biocompatible and biodegradable molecules. The low molecular weight (LMW) derivatives of the GY785 EPS produced by the deep-sea hydrothermal vent strain Alteromonas infernus have previously displayed some biological properties, similar to those of glycosaminoglycans (GAG), explored in cancer and tissue engineering. These GAG-mimetic derivatives are obtained through a free radical depolymerization process, which could, however, affect their structural integrity. In a previous study, we have shown that A. infernus produces depolymerizing enzymes active on its own...

Autores: Costa-Singh,Tainara; Jorge,Neuza.
Abstract The present study aims to evaluate the influence of extraction methods on the quality of bioactive compounds and antioxidant capacity in Pterodon emarginatusVogel (sucupira) oils. The oils were extracted from the sucupira seeds by Soxhlet and by the extraction system of Bligh &amp; Dyer. The oils were analyzed as to fatty acid profile, tocopherols, phytosterols, carotenoids, total phenolics, and total antioxidant capacity. The extraction by Soxhlet showed better yield of total lipids and was more efficient to extract tocopherols, phytosterols, and carotenoids, besides presenting better antioxidant activity by DPPH•. However, this method showed insufficient capacity to extract the polar lipid components of the sample, as evidenced by the low...

Autores: Blanluet, Arthur; Doray, Mathieu; Berger, Laurent; Romagnan, Jean-baptiste; Le Bouffant, Naig; Lehuta, Sigrid; Petitgas, Pierre.
Sound scattering layers (SSLs) are observed over a broad range of spatio-temporal scales and geographical areas. SSLs represent a large biomass, likely involved in the biological carbon pump and the structure of marine trophic webs. Yet, the taxonomic composition remains largely unknown for many SSLs. To investigate the challenges of SSL sampling, we performed a survey in a small study area in the Northern Bay of Biscay (France) by combining broadband and narrowband acoustics, net sampling, imagery and video recordings. In order to identify organisms contributing to the observed SSLs, we compared measured frequency spectra to forward predicted spectra derived from biological data. Furthermore, to assess the confidence in SSL characterization, we evaluated...

CHEMICAL CONTROL OF ASIAN SOYBEAN RUST AS A FUNCTION OF CULTIVAR, ROW SPACING AND SPRAY BAR SUPPORT SYSTEMS
Provedor de dados: 70
Autores: Hoffmann,Laercio L.; Roehrig,Rafael; Boller,Walter; Forcelini,Carlos A.
ABSTRACT Product deposition and foliar surface cover are highly impacting factors on the efficiency of foliar fungicides applied to soybean cultivars, due to their low mobility, with side effects on Asian soybean rust (ASR) control. Spray bar support systems, such as the air curtain (Vortex®) and the use of nozzles along the bar (Dropleg®), stand out as an alternative to obtain a better distribution of fungicide throughout the plant. In this study, two spray bar support systems (Vortex® and Dropleg®) were, therefore, evaluated and compared with the conventional spraying method based on the biological efficacy in ASR control. In order to do this, two harvests, with three spacing between rows and two cultivars were employed. Vortex® and Dropleg® spray bar...

Chemical control of leaf-cutting ants: how do workers disperse toxic bait fragments onto fungus garden?
Provedor de dados: 92
Autores: Catalani,Gabriela C.; Sousa,Kátia K.A.; Camargo,Roberto S. da; Caldato,Nadia; Matos,Carlos A.O.; Forti,Luiz C.
ABSTRACT Leaf-cutting ants are controlled with toxic baits. For the method’s greater efficiency, the baits must be distributed and processed by workers during fungus cultivation. To test hypotheses whether the mode of action of the active ingredients, which blocks the sodium channels and interrupts the production of ATP in the mitochondria, interferes with fragment distribution in nests; the dispersion of pellets fragments during fungus cultivation by workers was assessed, spatially referencing the fragment onto the fungus garden. Pellets fragments were randomly distributed, but the amount pellets fragments was influenced by the way that the active ingredient acts in the colony.

Autores: Briand, Enora; Reubrecht, Sébastien; Mondeguer, Florence; Sibat, Manoella; Hess, Philipp; Amzil, Zouher; Bormans, Myriam.
Freshwater cyanobacteria are known for their ability to produce bioactive compounds, some of which have been described as allelochemicals. Using a combined approach of co‐cultures and analyses of metabolic profiles, we investigated chemically mediated interactions between two cyanobacterial strains, Microcystis aeruginosa PCC7806 and Planktothrix agardhii PCC7805. More precisely, we evaluated changes in growth, morphology and metabolite production and release by both interacting species. Co‐culture of Microcystis with Planktothrix resulted in a reduction of the growth of Planktothrix together with a decrease of its trichome size and alterations in the morphology of its cells. The production of intracellular compounds by Planktothrix showed a slight...

Autores: Terezo,Rodrigo F.; Córdova,Franciele O. de; Sampaio,Carlos A. de P.
ABSTRACT In the production of glue-laminated timber (GLT), boards derived from planted forest wood with easy workability are glued on top of one another. The main objective of the present work was to evaluate the performance of paricá timber GLT beams (5 × 10 cm) on GLT. Three procedures were performed: (1) GLT beams (5 × 10 cm) were produced using natural lamellae without chemical preservatives; (2) the individual lamellae (2.5 × 5 cm) were chemically treated, and then glued together; and (3) the beams formed from the glued natural lamellae (5 × 10 cm) were treated chemically. The positions of lamellae on the beams were determined by their modulus of elasticity values (MOE), which were estimated by a non-destructive bending test with a three-point load....

Chenier Morphodynamics on the Amazon-Influenced Coast of Suriname, South America: Implications for Beach Ecosystem Services
Provedor de dados: 5
Autores: Anthony, Edward J.; Brunier, Guillaume; Gardel, Antoine; Hiwat, Michael.
The 350-km long coast of Suriname, South America, is part of a unique system in the world characterized by large-scale mud supply from the Amazon and exposed to Atlantic waves. Large banks migrate alongshore from the Amazon to the Orinoco delta, separated by ‘inter-bank’ zones. Banks dissipate waves, partially weld onshore, and are colonized by mangroves, whereas waves in inter-bank areas cause shoreline erosion, mitigated where rare cheniers develop. Cheniers assure coastal protection and recreational and ecosystem services, notably providing nesting sites for marine turtles. Cheniers are also under pressure from sand mining. In order to gain a better understanding of how these cheniers form and evolve, a study was conducted on Braamspunt beach, a major...

Regulation of food systems exists to ensure safety and enhance consumer confidence in the food which they purchase and consume. However, some regulatory systems fail to instil public confidence. In China for example, trust in the domestic food system is low as a consequence of multiple high-profile food scandals, many of which linked to food fraud. Fraud occurs when food is intentionally adulterated for economic gain and may, but not always, pose a risk to the safety of food. Food authenticity and quality may also be compromised. The focus of this research relates to how Chinese consumers perceive food fraud and make choices in the absence of trust in regulatory systems. Seven focus groups with middle class Chinese participants in tier 1 and 2 cities...

ABSTRACT:  Meningiomas are neoplasms that commonly involve the central nervous system of cats, while cholesteatomas are nodular granulomatous chronic lesions within the choroid plexus that are rarely reported in cats. This study described a case of cholesteatoma and non-communicating hydrocephalus associated to a third ventricle meningioma in a cat. Clinically, the cat had a 2-year history of behavioral changes, photophobia and motor incoordination. At the necropsy, a tan-brown mass totally occluded the third ventricle, causing a severe dilation of the lateral ventricles (non-communicating hydrocephalus). Microscopically, the mass was composed by a neoplastic proliferation of spindle cells arranged in bundles, containing in the center psammomatous bodies...

Autores: Trani, Tamires de Vecchi; Lyra, Natália Guerreiro; Pietroluongo, Bruno.
Cholesteatoma is an otologic disease, characterized as a benign aural epidermoid cyst. Clinical manifestations of this disease can be: otalgia, pain or inability to open the mouth, head tilt, facial paralysis, ataxia, and pain under temporomandibular joint palpation. Diagnosis is based on exams such as tomography, magnetic resonance imaging, and video-otoscopy; and histopathological examination is essential to confirm the diagnosis. Surgery is the most effective treatment, albeit it may not be curative, consisting of removing the remains of keratin and squamous epithelium of the middle ear. In Veterinary Medicine, this has a high rate of recurrence.

Provedor de dados: 74
Autores: Nascimento,Sarah do; Coelho,Marcus Alberto Nadruz; Cordeiro,Joel M. P.; Felix,Leonardo P.
Abstract The genus Anthurium has a Neotropical distribution, with karyotype predominance of x = 15, although some species show disploidy or polyploid variations. The karyotypes of seven species and different populations of Anthurium were analyzed using fluorochrome CMA and DAPI staining. The karyotypes were composed of meta- and submetacentric chromosomes, with numbers varying from 2n = 30 to 2n = 60. Supernumerary euchromatic chromosomes were observed in A. affine, and supernumerary heterochromatic chromosomes were observed in A. gladiifolium and A. petrophilum. Polyploidy was recurrent in the Anthurium species analyzed, with records of 2n = 30 and 60 in different A. pentaphyllum populations. Fluorochrome staining revealed different CMA+ banding...

The response of Argopecten purpuratus (Peruvian scallop) to environmental conditions was studied in the upwelling-influenced Bay of Paracas (Peru). Scallops growth and reproduction were monitored weekly over a 7-month period under two conditions (culture depths): on the bottom and 2 m above (suspended culture). At the same time, a high-frequency environmental monitoring was realized at the aforementioned depths. The results indicate that environmental conditions in the Bay are highly variable, especially during the summer: temperature fluctuations up to 8∘C were recorded in less than one day while oxic conditions ranged from oversaturation to anoxia. Milky-turquoise waters discoloration events (sulphide presence suspected) were simultaneously observed...

Autores: SOUTO,XÊNIA M.; BRANQUINHA,MARTA H.; SANTOS,ANDRÉ L.S.
Abstract: Candida haemulonii complex (C. haemulonii, C. haemulonii var. vulnera and C. duobushaemulonii) consists of emergent multidrug-resistant pathogens that cause bloodstream and deep-seated infections. However, little is known about their virulence factors. Herein, we evaluated the presence of extracellular serine peptidases in this fungal complex. Serine peptidase activity was measured by spectrophotometry using chromogenic peptide substrates to the S1 family. Chymotrypsin-, trypsin- and elastase-like activities were detected in all fungal isolates. Since higher chymotrypsin- and trypsin-like activities were observed from the cleavage of N-succinyl-Ala-Ala-Pro-Phe-pNa and N-benzoyl-Phe-Val-Arg-pNa, respectively, these substrates were selected for...

Descoberta de pesquisadores da Embrapa Uva e Vinho (RS) abre caminho para o desenvolvimento de macieiras que precisam de menos dias de frio para produzir. Eles descobriram o mecanismo de ação do gene ICEi no processo de indução e superação da dormência da planta, etapa fundamental para garantir a produção dos frutos. De acordo com a hipótese dos cientistas, esse gene funciona como um gatilho térmico que, ao ser estimulado pelo frio, dispara uma cascata de respostas como a indução da dormência, processo fundamental para plantas originalmente de clima temperado florescerem e produzirem frutos.

Ciguatera fish poisoning in Brazilian traveler to Caribbean
Provedor de dados: 55
Autores: Neves Junior,Cidney K.; Goldani,Luciano Z.
ABSTRACT Ciguatera poisoning is the most common form of non-bacterial food-poisoning from fish worldwide. The incidence among Brazilians returning from high-risk regions is unclear because it is not a mandatory reportable disease. We describe a previously healthy 53-year-old Brazilian woman developed Ciguatera fish poisoning while traveling to Havana, Cuba. Physicians and health care professionals should advise travelers to avoid eating ciguatoxic fish species and potentially toxic fish species in the Caribbean islands. Despite the prognosis for most cases is good with a short duration of self-limited symptoms, early recognition of the identifying clinical features of ciguatera can result in improved patient care.

Ciguatera poisoning in French Polynesia: insights into the novel trends of an ancient disease
Provedor de dados: 5
Autores: Chinain, M.; Gatti, C.m.; Roué, M.; Darius, H.t.
Ciguatera is a non-bacterial seafood poisoning highly prevalent in French Polynesia where it constitutes a major health issue and a major threat to food sustainability and food security for local populations. Ciguatera results from the bioaccumulation in marine food webs of toxins known as ciguatoxins, originating from benthic dinoflagellates in the genera Gambierdiscus and Fukuyoa. Ciguatera is characterized by a complex array of gastrointestinal, neurological and cardiovascular symptoms. The effective management of patients is significantly hampered by the occurrence of atypical forms and/or chronic sequelae in some patients, and the lack of both a confirmatory diagnosis test and a specific antidote. In addition, recent findings have outlined the...

In Cuba, ciguatera poisoning associated with fish consumption is the most commonly occurring non-bacterial seafood-borne illness. Risk management through fish market regulation has existed in Cuba for decades and consists of bans on selected species above a certain weight; however, the actual occurrence of ciguatoxins (CTXs) in seafood has never been verified. From this food safety risk management perspective, a study site locally known to be at risk for ciguatera was selected. Analysis of the epiphytic dinoflagellate community identified the microalga Gambierdiscus. Gambierdiscus species included six of the seven species known to be present in Cuba (G. caribaeus, G. belizeanus, G. carpenteri, G. carolinianus, G. silvae, and F. ruetzleri). CTX-like...

Cirrhotic cardiomyopathy historically has been confused as alcoholic cardiomyopathy. The key points for diagnosis of cirrhotic cardiomyopathy have been well explained, however this entity was neglected for a long time. Nowadays the diagnosis of this entity has become important because it is a factor that contributes significantly to morbidity-mortality in cirrhotic patients. Characteristics of cirrhotic cardiomyopathy are a hyperdynamic circulatory state, altered diastolic relaxation, impaired contractility, and electrophysiological abnormalities, particularity QT interval prolongation. The pathogenesis includes impaired function of beta-receptors, altered transmembrane currents and overproduction of cardiodepressant factors, such as nitric oxide,...

Climate change is impacting marine ecosystems and their goods and services in diverse ways, which can directly hinder our ability to achieve the Sustainable Development Goals (SDGs), set out under the 2030 Agenda for Sustainable Development. Through expert elicitation and a literature review, we find that most climate change effects have a wide variety of negative consequences across marine ecosystem services, though most studies have highlighted impacts from warming and consequences of marine species. Climate change is expected to negatively influence marine ecosystem services through global stressors—such as ocean warming and acidification—but also by amplifying local and regional stressors such as freshwater runoff and pollution load. Experts indicated...

ABSTRACT A female dog was treated at the Veterinary Hospital Governador Laudo Natel for symptomscaused by an intra-abdominal gossypiboma (gossypium: cotton; boma: place of hiding). Showing high morbidity and mortality, the gossypiboma is a granulomatous reaction that is formed in response to exposure to a textile matrix. The objective of this report is to describe the clinical and pathological findings of an intra-abdominal gossypiboma in a female dog. This patient arrived at urgent care showing increased abdominal volume, pain, and cachexia. Ultrasonography showed a regular contour formation that could not be completely delimited. The patient underwent exploratory laparotomy and died in the postoperative period. The gossypiboma had a smooth, firm, and...

ABSTRACT The biological behaviour of the tumours vary according to the species in which they occur, its location within the cavity, clinical stage and histopathological nature. Lingual neoplasms are generally uncommon in companion animals. Rhabdomyosarcomas are malignant, solid, aggressive formations with high metastatic potential. The clinical signs are variable and a definitive diagnosis can only be reached through histopathological analysis of biopsy and necropsy specimen. In some cases, immunohistochemical study may be needed to confirm the diagnosis. This paper aims to highlight important points about this uncommon condition in dogs, using a case report of lingual rhabdomyosarcoma, which showed no evidence of metastasis after diagnosis, nor of local...

Abstract Rare diseases are defined as conditions with a prevalence of no more than 6.5 per 10,000 people. Although each rare disease individually affects a small number of people, collectively, the 6,000 to 8,000 rare conditions (80% of them with genetic cause) affect around 8% of the world’s population. Research about the natural history and underlying pathophysiological mechanisms of rare diseases, as well as clinical trials with new drugs, are important and necessary to develop new strategies for the treatment of these conditions. This report describes the experience of a clinical research group working with rare diseases in a reference center for lysosomal diseases in Brazil (Medical Genetics Service, Hospital de Clínicas de Porto Alegre).

Autores: Fatobene,Bárbhara Joana dos Reis; Gonçalves,Wallace; Oliveira,Claudio Marcelo Gonçalves; Guerreiro Filho,Oliveiro.
ABSTRACT: Plants of Coffea arabica Icatu IAC 925 germplasm show resistance to Meloidogyne paranaensis under field conditions, but with variable rates of segregation. One mother plant, IAC 3, of Icatu IAC 925 was evaluated under controlled conditions through the reaction of its clones, obtained by somatic embryogenesis. Reproduction of nematodes in clones were compared with an open-pollinated progeny from the same mother plant, C. arabica cultivar Mundo Novo IAC 515-20, susceptible to nematodes, and Clone IAC 1, also susceptible and obtained by somatic embryogenesis. Open-pollinated progeny showed segregation to resistance and was classified as susceptible according to the reproduction factor. The average number of nematodes (eggs and J2) per gram of roots...

Cnidom variation through distinct developmental stages in the sea anemone Aulactinia marplatensis (Zamponi, 1977) (Cnidaria: Actiniaria)
Provedor de dados: 42
Autores: GARESE,AGUSTÍN; GONZÁLEZ-MUÑOZ,RICARDO; ACUÑA,FABIÁN H.
The cnidae are the exclusive diagnostic structures of phylum Cnidaria. The inventory of all cnidae types of a particular species is called the cnidom. The study of cnidae has been widely addressed in all classes of cnidarians. Particularly in the order Actiniaria (sea anemones), the study of the composition, size and distribution of cnidae is essential to the identification and description of species. In the present study, we examine the cnidom of the sea anemone Aulactinia marplatensis in three different stages of development throughout its life cycle. We found that the composition and abundance patterns are very similar between the adult and juvenile stages, although significant differences in the size capsules were found between both stages and in all...

Autores: SIQUEIRA, F.; GIACHETTO, P. F.
Variações no número de cópias de regiões específicas do DNA, ou simplesmente CNVs (Copy Number Variations), constituem um tipo de marcador molecular que é encontrado com frequência nos genomas de mamíferos e plantas. Em humanos, o impacto das CNVs sobre os fenótipos já foi relatado em características adaptativas, mortalidade embrionária e em algumas doenças complexas como autismo, esquizofrenia, doença de Chron, artrite reumatoide, diabetes tipo I e obesidade. Comparada aos SNPs (Single Nucleotide Polymorphism), as CNVs envolvem um número maior de sequências genômicas, apresentando, potencialmente, um impacto mais pronunciado na expressão gênica, em função de alterações na estrutura e na dosagem gênica. Assim, acredita-se que esse marcador também exerça um...

To understand and predict the physical, chemical, and biological processes at play in coastal and nearshore marine areas requires an integrated, interdisciplinary approach. The case study of the French structuration of coastal ocean and nearshore observing systems provides an original overview on a federative research infrastructure named ILICO. It is a notable example of national structuration and pan-institution efforts to investigate the forefront of knowledge on the processes at work within the critical coastal zone. ILICO comprises, in a pluridisciplinary approach, eight distributed network-systems of observation and data analysis that are accredited and financially supported by French research institutions and the French Ministry for Higher...

Coastal waters freshening and extreme seasonality affect organic matter sources, quality, and transfers in a High Arctic fjord (Young Sound, Greenland)
Provedor de dados: 5
Autores: Bridier, Guillaume; Meziane, Tarik; Grall, Jacques; Chauvaud, Laurent; Sejr, Mikael Kristian; Menneteau, Sylvain; Olivier, Frederic.
Arctic benthic ecosystems are expected to experience strong modifications in the dynamics of primary producers and/or benthic-pelagic coupling under climate change. However, lack of knowledge about the influence of physical constraints (e.g. ice-melting associated gradients) on organic matter sources, quality, and transfers in systems such as fjords can impede predictions of the evolution of benthic-pelagic coupling in response to global warming. Here, sources and quality of particulate organic matter (POM) and sedimentary organic matter (SOM) were characterized along an inner-outer gradient in a High Artic fjord (Young Sound, NE Greenland) exposed to extreme seasonal and physical constraints (ice-melting associated gradients). The influence of the...

Coccolithophore productivity at the western Iberian Margin during the middle Pleistocene (310 – 455 ka) – evidence from coccolith Sr/Ca data
Provedor de dados: 5
Autores: Cavaleiro, Catarina; Voelker, Antje Hl; Stoll, Heather; Baumann, Karl-heinz; Kucera, Michal.
Coccolithophores contribute significantly to the marine primary productivity and play a unique role in ocean biogeochemistry by using carbon for photosynthesis (biological pump) and also for calcification (carbonate pump). Despite the importance of including coccolithophores in global climate models to allow better predictions of the climate system's responses to planetary change, highly uncertain coccolithophore paleoproductivity past reconstructions mostly relied on proxies dependent on accumulation and sedimentation rates, and preservation conditions. In this study we used an independent proxy, based on the coccolith fraction (CF) Sr/Ca ratio, to reconstruct coccolithophore productivity. We used the marine sediment core MD03-2699 from the western...

Cocoa Pod Ash as Bio-Based Catalyst for Biodiesel Production from Waste Chicken Fat
Provedor de dados: 111
Autores: Odetoye, Temitope Elizabeth; Amusan, Greatness S.
The growing interest in using sustainable raw materials coupled with the need to reduce the over- dependence on non-renewable petroleum resources has made agricultural residues attractive raw material for biofuel production. The potential utilization of cocoa pod ash (CPA) as a bio-based catalyst for the production of biodiesel from waste chicken fat was investigated. Bio-based catalyst was obtained from cocoa pods by ashing method. The catalyst was subjected to scanning electron microscope (SEM) analysis. The experimental design was based on a five level, two factor central composite design. CPA was used in the preparation of biodiesel from waste chicken fat (WCF) using a two-step esterification-transesterification process. The highest biodiesel yield of...

Cocoa propagation, technologies for production of seedlings
Provedor de dados: 94
Autores: Sodré,George Andrade; Gomes,Augusto Roberto Sena.
Abstract  The vegetative propagation in cacao has been used in Central America since the beginning of the last century. However, only from the end of the century this technique has been intensified in the state of Bahia, where vegetative propagation changes have increased the yield of cocoa growing areas, especially those using other technologies associated with clonal seedlings. The use of clonal garden to collect stems in nursery can reduce by 80% the space required for maintenance of stock plants. On the other hand, the buds obtained from orthotropic and plagiotropic shoots are used to improve the performance protocols and reduce production costs of seedlings. Among the current and future challenges in the production of cocoa seedlings emphasizes the...

Cold-water coral mounds in the southern Alboran Sea (western Mediterranean Sea): Internal waves as an important driver for mound formation since the last deglaciation
Provedor de dados: 5
Autores: Wang, Haozhuang; Lo Iacono, Claudio; Wienberg, Claudia; Titschack, Jürgen; Hebbeln, Dierk.
Cold-water corals (CWCs) are widely distributed in the entire Alboran Sea (western Mediterranean Sea), but only along the Moroccan margin they have formed numerous coral mounds, which are constrained to the West and the East Melilla CWC mound provinces (WMCP and EMCP). While information already exists about the most recent development of the coral mounds in the EMCP, the temporal evolution of the mounds in the WMCP was unknown up to the present. In this study, we present for the first time CWC ages obtained from four sediment cores collected from different mounds of the WMCP, which allowed to decipher their development since the last deglaciation. Our results revealed two pronounced periods of coral mound formation. The average mound aggradation rates were...

A hérnia diafragmática é caracterizada pela passagem das vísceras abdominais para a cavidade torácica, após a ruptura do diafragma. A causa mais comum de hérnia diafragmática em cães e gatos são acidentes automobilísticos. Do mesmo modo, os cachorros-do-mato (Cerdocyon thous) também são vítimas frequentes desses acidentes, pois estão cada vez mais próximos do convívio com o homem. O exame radiográfico, geralmente, é a primeira escolha de exame de imagem em animais com suspeita de ruptura diafragmática. Existem poucos relatos de casos diagnosticados com o emprego da ultrassonografia, entretanto, esta técnica pode ser útil quando não for conclusivo o diagnóstico por meio do exame radiográfico. Este trabalho relata um caso de hérnia diafragmática em...

Impacts from natural and anthropogenic coastal hazards are substantial and increasing significantly with climate change. Coasts and coastal communities are increasingly at risk. In addition to short-term events, long-term changes, including rising sea levels, increasing storm intensity, and consequent severe compound flooding events are degrading coastal ecosystems and threatening coastal dwellers. Consequently, people living near the coast require environmental intelligence in the form of reliable short-term and long-term predictions in order to anticipate, prepare for, adapt to, resist, and recover from hazards. Risk-informed decision making is crucial, but for the resulting information to be actionable, it must be effectively and promptly communicated...

Provedor de dados: 5
Autores: Chassot, Emmanuel; Sabarros, Philippe; Maufroy, A; Ruiz, J; Ramos, Ml; Barreau, E; Barde, Julien.
Observations of turtles in the open-ocean are essential to complement the information collected at nesting sites and rookeries, especially during the ‘lost years’ of their surface-pelagic juvenile phase. We used a large dataset of observations at sea collected onboard Seychelles, Spanish and French purse seiners over the period 2003-2019 to describe the occurrence of five species of turtles in the Western Indian Ocean: green ( Chelonia mydas ), loggerhead ( Caretta caretta ), leatherback ( Dermochelys coriacea ), Olive ridley ( Lepidochelys olivacea ) and hawksbill ( Eretmochelys imbricata ). A total of 895 turtles were recorded by human observers, 487 turtles after having been caught in the purse seine and hauled onboard the vessels and 408 turtles...

Autores: Vannier, Jean; Vidal, Muriel; Marchant, Robin; El Hariri, Khadija; Kouraiss, Khaoula; Pittet, Bernard; El Albani, Abderrazak; Mazurier, Arnaud; Martin, Emmanuel.
Interactions and coordination between conspecific individuals have produced a remarkable variety of collective behaviours. This co-operation occurs in vertebrate and invertebrate animals and is well expressed in the group flight of birds, fish shoals and highly organized activities of social insects. How individuals interact and why they co-operate to constitute group-level patterns has been extensively studied in extant animals through a variety mechanistic, functional and theoretical approaches. Although collective and social behaviour evolved through natural selection over millions of years, its origin and early history has remained largely unknown. In-situ monospecific linear clusters of trilobite arthropods from the lower Ordovician (ca 480 Ma) of...

Autores: Fu, M.; Crouw, P.W.; Bai, Q.; Zhang, P.F.; Xiang, J.; Guo, Y.S.; Zhao, F.F.; Yang, M.M.; Hong, N.; Xu, W.X.; Wang, G.P.
Colletotrichum species are plant pathogens, saprobes, and endophytes on a range of economically important hosts. However, the species occurring on pear remain largely unresolved. To determine the morphology, phylogeny and biology of Colletotrichum species associated with Pyrus plants, a total of 295 samples were collected from cultivated pear species (including P. pyrifolia, P. bretschneideri, and P. communis) from seven major pearcultivation provinces in China. The pear leaves and fruits affected by anthracnose were sampled and subjected to fungus isolation, resulting in a total of 488 Colletotrichum isolates. Phylogenetic analyses based on six loci (ACT, TUB2, CAL, CHS-1, GAPDH, and ITS) coupled with morphology of 90 representative isolates revealed that...

Autores: Fonseca, Bruno Costa da.
Este trabalho tem por intento apresentar parte da discussão teórica de um dos autores mais reverenciados dentro da sociologia rural brasileira: José de Souza Martins. Sua produção teórica abarca uma diversidade muita ampla de temas, contudo, neste artigo, procurou-se evidenciar temas inerentes a questão agrária nos idos da década de 80. Através da revisão de literatura de suas principais obras, percebe-se um embate travado contra a esquerda leninista da época e, com efeito, contra a forma de se pensar a reforma agrária a partir das cidades. O papel da mediação social foi tema recorrente nas publicações de Martins, mas pensado na perspectiva da ação política da Igreja que deveria “dar voz aos excluídos” do campo e não apenas falar por eles. Martins, que...

ABSTRACT Exposure to Pneumocystis jirovecii (P. jirovecii) can lead to a wide variety of presenting features ranging from colonization in immunocompetent patients with lung disease, to invasive infections in immunocompromised hosts. Colonization by this fungus in patients with chronic obstructive pulmonary disease (COPD) could be associated with higher rates of exacerbations and impaired lung function in these patients.Our objective was to determine whether colonization by P. jirovecii in patients with COPD is associated with increased exacerbations and deterioration of lung function.This was a prospective cohort study on patients with COPD. All participants meeting selection criteria underwent clinical and microbiological assessments and were then...

A avaliação da qualidade do embrião é um fator determinante para o sucesso da produção in vitro de embriões (PIVE) e das demais técnicas de reprodução assistida, pois a seleção e transferência daqueles de melhor qualidade aumentam a taxa de gestação, melhorando a eficiência e reduzindo custos. Rotineiramente, a seleção de embriões produzidos por técnicas de reprodução assistida é realizada por avaliação morfológica. Porém, este método tem limitações por envolver observações subjetivas, como baixa repetibilidade e alta variação entre os avaliadores. Nos últimos anos, outros métodos têm sido desenvolvidos e utilizados na tentativa de se estabelecer uma seleção mais eficiente. Um destes é o uso da coloração diferencial, método que informa, não somente sobre o...

Colour plasticity in the shells and pearls of animal graft model Pinctada margaritifera assessed by HSV colour quantification
Provedor de dados: 5
Autores: Stenger, Pierre-louis; Vidal-dupiol, Jeremie; Reisser, Celine; Planes, Serge; Ky, Chin-long.
The bivalve Pinctada margaritifera has the capacity to produce the most varied and colourful pearls in the world. Colour expression in the inner shell is under combined genetic and environmental control and is correlated with the colour of pearls produced when the same individual is used as a graft donor. One major limitation when studying colour phenotypes is grader subjectivity, which leads to inconsistent colour qualification and quantification. Through the use of HSV (Hue Saturation Value) colour space, we created an R package named ‘ImaginR’ to characterise inner shell colour variations in P. margaritifera. Using a machine-learning protocol with a training dataset, ImaginR was able to reassign individual oysters and pearls to predefined human-based...

ABSTRACT Characterization and evaluation of genotypes conserved in the germplasm banks have become of great importance due to gradual loss of genetic variability and search for more adapted and productive genotypes. This can be obtained through several ways, generating quantitative and qualitative data. Joint analysis of those variables may be considered a strategy for an accurate germplasm characterization. In this study we aimed to evaluate different clustering techniques for characterization and evaluation of Capsicum spp. accessions using combinations of specific measures for quantitative and qualitative variables. A collection of 56 Capsicum spp. accessions was characterized based on 25 morphoagronomic descriptors. Six quantitative distances were used...

ABSTRACT Evaluation of the genetic potential of parent plants is fundamental for obtaining superior populations with desirable agronomic characters. The aim of this work was to obtain estimates of the general and specific combining abilities of five soybean parents to identify the most promising parents and hybrid combinations for the development of superior genotypes for grain yield. In this study, two groups of soybean cultivars were selected: group I resistance (UFUS 7910 and BR/MG 46 Conquista) and group II (TMG 4182, TMG 4185 and BRSGO Chapadões). The parents were crossedin a 2 x 3 partial diallel scheme, and the experiment was analyzed according to Griffing’s (1956) parent and F1 model and adapted by Geraldi and Miranda Filho (1988).

Made up of calcareous coralline algae, maerl beds play a major role as ecosystem engineers in coastal areas throughout the world. They undergo strong anthropogenic pressures, which may threaten their survival. The aim of this study was to gain insight into the future of maerl beds in the context of global and local changes. We examined the effects of rising temperatures (+3°C) and ocean acidification (−0.3 pH units) according to temperature and pH projections (i.e., the RCP 8.5 scenario), and nutrient (N and P) availability on three temperate maerl species (Lithothamnion corallioides, Phymatolithon calcareum, and Lithophyllum incrustans) in the laboratory in winter and summer conditions. Physiological rates of primary production, respiration, and...

Autores: Cominassi, Louise; Moyano, Marta; Claireaux, Guy; Howald, Sarah; Mark, Felix C.; Zambonino-infante, Jose-luis; Le Bayon, Nicolas; Peck, Myron A.
Ocean acidification and ocean warming (OAW) are simultaneously occurring and could pose ecological challenges to marine life, particularly early life stages of fish that, although they are internal calcifiers, may have poorly developed acid-base regulation. This study assessed the effect of projected OAW on key fitness traits (growth, development and swimming ability) in European sea bass (Dicentrarchus labrax) larvae and juveniles. Starting at 2 days post-hatch (dph), larvae were exposed to one of three levels of PCO2 (650, 1150, 1700 μatm; pH 8.0, 7.8, 7.6) at either a cold (15°C) or warm (20°C) temperature. Growth rate, development stage and critical swimming speed (Ucrit) were repeatedly measured as sea bass grew from 0.6 to ~10.0 (cold) or ~14.0...

ABSTRACT: Although water deficit and iron deficiency chlorosis are common environmental stresses in the Mediterranean area, few data are reported in the literature on their effects on vineyards, when acting simultaneously. The main objective of this research was to study the combined effects of iron deficiency and water status on vigor, yield and fruit composition in rainfed vineyards. Moreover, the investigation aimed to evaluate the feasibility of using foliar chlorophyll content (Chl) and predawn leaf water potential (LWP), measured at veraison, to assess potential quality of grapes in the framework of precision viticulture. For this, 24 non-irrigated ‘Tempranillo’ vineyard subzones were monitored in Ribera del Duero (North-Central Spain) during three...

Abstract The white mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is one of the most important diseases of soybean. The objective of the present work was to evaluate the soybean reaction to the fungus S. sclerotiorum, which causes white mold, in a partial diallel with 50 crosses. The Group I of parents was composed of ten experimental lines with high grain yield and the group II consisted in five genotypes with possible resistance to white mold. Ten plants of each cross in the F4 generation and the parents were evaluated for reaction to fungus infection using the method of inoculation in detached leaves in order to assess the severity of the disease and to later estimate the combining abilities. Estimates of the specific combining ability (SCA)...

Autores: Haas, Brechtje, de; Hoekstra, Nyncke; Schoot, Jan Rinze, van der; Visser, Eric J.W.; Kroon, Hans, de; Eekeren, N. van.
Grass-clover mixtures show many benefits for sustainable agriculture. In the Netherlands, organic farmers often work together in a so-called partner farm concept, with the aim to close nutrient cycles on a regional level. In this system, arable farms grow one-year grass-clover leys, as fodder for a livestock farm, in exchange for, e.g., manure. This practice could also be used in the transition of conventional farms towards a more circular regenerative and nature inclusive agriculture. In the current experiment we assessed the effect of a range of grass (Lolium perenne: Lp, Lolium multiflorum: Lm) and clover (Trifolium pratense: Tp and Trifolium repens: Tr) monocultures and mixtures on both below- and aboveground parameters in light of benefits for...

Provedor de dados: 5
Autores: Besson, Mathieu; Allal, Francois; Chatain, Beatrice; Vergnet, Alain; Clota, Frederic; Vandeputte, Marc.
Measuring individual feed intake of fish in farms is complex and precludes selective breeding for feed conversion ratio (FCR). Here, we estimated the individual FCR of 588 sea bass using individual rearing under restricted feeding. These fish were also phenotyped for their weight loss at fasting and muscle fat content that were possibly linked to FCR. The 588 fish were derived from a full factorial mating between parental lines divergently selected for high (F+) or low (F–) weight loss at fasting. The pedigree was known back to the great grand-parents. A subset of 400 offspring and their ancestors were genotyped for 1,110 SNPs which allowed to calculate the genomic heritability of traits. Individual FCR and growth rate in aquarium were both heritable...

Combining multiple data sets to unravel the spatiotemporal dynamics of a data-limited fish stock
Provedor de dados: 5
Autores: Pinto, Cecilia; Travers-trolet, Morgane; Macdonald, Jed; Rivot, Etienne; Vermard, Youen.
The biological status of many commercially-exploited fishes remains unknown, mostly due to a lack of data necessary for their assessment. Investigating the spatio-temporal dynamics of such species can lead to new insights into population processes, and foster a path towards improved spatial management decisions. Here, we focused on striped red mullet (Mullus surmuletus), a widespread, yet data-limited species of high commercial importance. Aiming to quantify range dynamics in this data-poor scenario, we combined fishery-dependent and -independent datasets through a series of Bayesian mixed-effects models designed to capture monthly and seasonal occurrence patterns near the species’ northern range limit across 20 years. Combining multiple datasets allowed...

Understanding the genetic and evolutionary impacts of stocking on wild fish populations has long been of interest as negative consequences such as reduced fitness and loss of genetic diversity are commonly reported outcomes. In an attempt to sustain a fishery, managers implemented nearly five decades of extensive stocking of over a million Muskellunge (Esox masquinongy), a native species in the Lower St. Lawrence River (Québec, Canada). We investigated the effect of this stocking on population genetic structure and allelic diversity in the St. Lawrence River in addition to tributaries and several stocked inland lakes. Using Genotype‐By‐Sequencing (GBS), we genotyped 643 individuals representing 22 locations and combined this information with forward...

Comercialização de produtos florestais não madeireiros em farmácias de manipulação e de produtos naturais.
Provedor de dados: 14
Autores: LIRA-GUEDES, A. C.; OLIVEIRA, B. R. de; RAMOS, M. S.; GUEDES, M. C.
Embora haja uma ampla gama de Produtos Florestais Não Madeireiros (PFNM) na Amazônia, a variedade desses produtos, que pode ser explorada economicamente, é limitada. Isso porque vários desses produtos ainda não têm uso industrial, embora haja o uso tradicional e o reconhecido efeito no tratamento de inúmeras doenças pelos "povos da floresta". Assim, na maioria das vezes, a comercialização de grande parte dos PFNM explorados pelos amazônidas, fica restrita às próprias comunidades, porque as informações técnicas sobre esses produtos ainda são muito incipientes. Pouco se sabe sobre a ecologia dos PFNM e, quando se trata de padrões para comercialização e abastecimento da indústria de fármacos e cosméticos, as informações se tornam mais escassas ainda. No...

Commerce et santé des veaux «excédentaires» en zone de montagne: une étude des Grisons
Provedor de dados: 21
Autores: Janett, Rut; Oehen, Bernadette.
Il existe peu d’informations concernant la gestion des veaux en montagne. Dans cette zone d’exploitation agricole, l’élevage occupe une place importante, marquée par l’économie alpestre. Aux fins de l’étude, onze chefs d’exploitations laitières et d’exploitations d’engraissement du canton des Grisons ont été interrogés sur la santé des veaux. Leurs réponses ont été analysées à la lumière de la Theory of Planned Behavior ou TPB (théorie du comportement planifié) développée par Ajzen. Les personnes interrogées exercent le commerce des veaux principalement à l’échelle régionale. En raison de l’estivage, le commerce des veaux est saisonnier. Certains décrivent une coopération étroite entre les exploitations laitières et les exploitations d’engraissement. Cela...

The emergence of longline fishing around the world has been concomitant with an increase in depredation-interactions by odontocete whales (removal of fish caught on hooks), resulting in substantial socio-economic and ecological impacts. The extent, trends and underlying mechanisms driving these interactions remain poorly known. Using long-term (2003–2017) datasets from seven major Patagonian toothfish (Dissostichus eleginoides) longline fisheries, this study assessed the levels and inter-annual trends of sperm whale (Physeter macrocephalus) and/or killer whale (Orcinus orca) interactions as proportions of fishing time (days) and fishing area (spatial cells). The role of fishing patterns in explaining between-fisheries variations of probabilities of...

Commercial traceability of Arapaima spp. fisheries in the Amazon Basin: can biogeochemical tags be useful?
Provedor de dados: 5
Autores: Pereira, Luciana A.; Santos, Roberto V.; Hauser, Marília; Duponchelle, Fabrice; Carvajal, Fernando; Pecheyran, Christophe; Bérail, Sylvain; Pouilly, Marc.
The development of analytical tools to determine the origin of fish is useful to better understand patterns of habitat use and to monitor, manage and control fisheries, including certification of food origin. The application of isotopic procedures to study fish calcified structures (scales, vertebrae, and otoliths) may provide robust information about the fish geographic origin and environmental living conditions. In this study, we used Sr and C isotopic markers recorded in otoliths of wild and farmed commercialized pirarucu (Arapaima spp.) to evaluate their prediction potential to trace the fish origin. Wild and farm fish specimens, as well as food used for feeding pirarucu in captivity, were collected from different sites. Isotope analyses of otoliths...

Autores: Silva,Anderson Gonçalves da; Boiça Junior,Arlindo Leal; Farias,Paulo Roberto da Silva; Souza,Bruno Henrique Sardinha de; Rodrigues,Nara Elisa Lobato; Carbonell,Sérgio Augusto Morais.
ABSTRACT: Whitefly Bemisia tabaci (Gennadius) biotype B is the major pest of common bean (Phaseolus vulgaris L.) in Brazil and other countries. Host plant resistance is one of the cornerstones of Integrated Pest Management (IPM), and assessment of cultivars for insect resistance is fundamental to provide farmers options for pest control. This study evaluated common bean resistance to whitefly in the winter and rainy seasons in Jaboticabal, Brazil, and correlated the infestation with climatic factors. The plant part and development period of common bean that are more susceptible to whitefly infestation were also examined for potential use in IPM. Field experiments were carried out using 18 and 19 commercial cultivars in the winter and rainy seasons,...

Common moist diet replacement to promote sustainable Cobia Rachycentron canadum (Linnaeus) near- shore farming in Brazil
Provedor de dados: 63
Autores: Landuci,Felipe Schwahofer; Rombenso,Artur Nishioka; Pontes,Marcelo Duarte; Maia,Marcelo Pereira; Eler,Giselle; Araujo,Bruno Cavalheiro; Poersch,Luis Henrique da Silva.
ABSTRACT: Cobia is one of the most promising warm water aquaculture species. In Brazil, cobia farming began in 2008 in the state of Rio de Janeiro from experimental scale facilities to regular near-shore farms based on fresh/frozen fish diets composed mostly of Sardinella sp. Despite the encouraging results achieved in the promotion of sustainable cobia farming, we advocate the replacement of fresh/frozen fish by a practical formulated feed. This experiment evaluated the zootechnical performance and environmental efficiency of moist and practical formulated feeds in early grow-out phases in the cycle of cobia nearshore cage culture. Four hundred and twenty juvenile cobia (151 ± 7 g) were fed with moist feed and practical formulated feed for 56 days....

Community financing in the German organic food sector: a key for sustainable food systems?
Provedor de dados: 21
Autores: Behrendt, Gerlinde; Peter, Sarah; Sterly, Simone; Häring, Anna Maria.
The rise of socially responsible and impact investing funds provides evidence for an increased interest private investors have in combining their financial and ethical concerns. At the same time, citizens increasingly engage in food networks and take on a vital role in the governance of agri-food systems. These developments might benefit farms and firms which are committed to sustainable food and seek funding. Through different community financing models, they can involve citizens who aim to support the development of a more sustainable food system.  This contribution presents case study evidence on community financing in the German organic food sector and discusses the role it can play in food system transformation.

Predicting responses of plankton to variations in essential nutrients is hampered by limited in situ measurements, a poor understanding of community composition, and the lack of reference gene catalogs for key taxa. Iron is a key driver of plankton dynamics and, therefore, of global biogeochemical cycles and climate. To assess the impact of iron availability on plankton communities we explored the comprehensive bio‐oceanographic and ‐omics datasets from Tara Oceans in the context of the iron products from two state‐of‐the‐art global scale biogeochemical models. We obtained novel information about adaptation and acclimation towards iron in a range of phytoplankton, including picocyanobacteria and diatoms, and identified whole sub‐communities co‐varying with...

Comparative assessment of two proxies of fish discard survival
Provedor de dados: 5
Autores: Morfin, Marie; Kopp, Dorothee; Benoît, Hugues P.; Méhault, Sonia.
Two vitality index approaches have been demonstrated to be good proxies of discard survival in similar fishing and environmental conditions: Reflex Action Mortality Predictors combined with injuries (RI) scores that measure the proportion of impaired reflexes and injuries, and a simpler, quicker, but less precise approach based on ordinal categories related to fish body movements and injuries (semi-quantitative assessment, SQA). This study assessed and compared these two approaches for five species (two flatfishes, skates, a seabass and a catshark) discarded in a coastal otter trawl fishery in the Bay of Biscay. All species displayed good vitality status according to both indices and were not very sensitive to the fishing nor their biological conditions....

ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to evaluate against this pest. The entomopathogenic viruses like nuclear polyhedrosis virus (NPV), a member of baculoviruses, can be the potential candidates for better control against ABW. The present study was conducted to assess the comparative efficacy of NPV and Spinosad 240SC (with the concentration of 250 mL · ha-1) against ABW in the controlled environment. The ABW was treated with different...

Provedor de dados: 74
Autores: Peng,Xiaojian; Wang,Qianqian; Zhao,Yang; Li,Xiaoyu; Ma,Qing.
Abstract SPLs are plant-specific transcription factors that play important regulatory roles in plant growth and development. Systematic analysis of the SPL family has been performed in numerous plants, such as Arabidopsis, rice, and Populus. However, no comparative analysis has been performed across different species to examine evolutionary features. In this study, we present a comparative analysis of SPLs in different species. The results showed that 84 SPLs of the four species can be divided into six groups according to phylogeny. We found that most of the SPL-containing regions in maize showed extensive conservation with duplicated regions of rice and sorghum. A gene duplication analysis in maize indicated that ZmSPLs showed a significant excess of...

ABSTRACT Present study evaluated carcass and meat quality attributes of broilers, broiler breeders and Aseel chickens. Sixty birds from each chicken genotype (broiler, broiler breeder and Aseel chickens; five-wk-old broilers and 60-wk-old Aseel chickens and broiler breeders) were evaluated. Birds were maintained under similar environment for 21 days, and then slaughtered to analyze their carcass qualitative and organoleptic characteristics. No carcass yield differences were detected among genotypes. Aseel chickens had heavier neck, followed by broiler breeder and broiler (p&lt;0.0001). Higher liver (p&lt;0.0001), intestine (p&lt;0.0001), ribs and back (p=0.0014) yields were obtained in broilers than in broiler breeders and Aseel chickens. Females showed...

Autores: ZHU,JIANGWEI; ZHAO,YAN; RUAN,HONGHUA.
Abstract: The strains CM-Z19 and CM-Z6, which are capable of highly degrading chlorpyrifos-methyl, were isolated from soil. They were identified as Bacillus megaterium CM-Z19 and Pseudomonas syringae CM-Z6, respectively, based on the 16S rRNA and an analysis of their morphological, physiological and biochemical characteristics. The strain CM-Z19 showed 92.6% degradation of chlorpyrifos-methyl (100 mg/L) within 5 days of incubation, and the strain CM-Z6 was 99.1% under the same conditions. In addition, the degradation characteristics of the two strains were compared and studied, and the results showed that the strain CM-Z19 had higher phosphoesterase activity and ability to degrade the organophosphorus pesticide than did the strain CM-Z6. However, the...

Comparing social representation of water quality in coastal lagoons with normative use of ecological indicators
Provedor de dados: 5
Autores: Audouit, Christelle; Pasqualini, Vanina; De Wit, Rutger; Flanquart, Herve; Deboudt, Philippe; Rufin-soler, Caroline.
Coastal lagoons are important for coastal and marine biodiversity. Nevertheless, they are very sensitive and vulnerable to human impacts, which often result in a decrease of their biodiversity and degradation of their water quality. Considering recent efforts for ecological restoration of coastal lagoons, it appears appropriate to compare the social representations of users of the coastal lagoons and of inhabitants, with ecological diagnoses of biodiversity and water quality. The main question is whether there is congruence between water quality defined by environmental criteria on one hand and the social representations of these issues by lagoon users and local populations on the other hand? How can we explain the social representations of lagoons...

Autores: Bieber, A.; Wallenbeck, A.; Spengler Neff, A.; Leiber, F.; Simantke, C.; Knierim, U.; Ivemeyer, S.
Although the use of local breeds is recommended by organic regulations, breed comparisons performed under organic production conditions with similar production intensities are scarce. Therefore, we compared data of local and widely used Holstein dairy cattle breeds from 2011 to 2015 regarding production, fertility and health from German and Swedish organic farms with similar management intensities within country. In Germany, the energy-corrected total milk yield tended to be lower in the local breed Original Angler Cattle (AAZ, 5193 kg) compared to the modern German Holstein Friesian breed (HO, 5620 kg), but AAZ showed higher milk fat and protein contents (AAZ v. HO: 5.09% v. 4.18% and 3.61% v. 3.31%, respectively). In Sweden, the widely used modern...

Comparison of Physicochemical and Functional Properties of Chicken and Duck Egg Albumens
Provedor de dados: 89
Autores: Chaiyasit,W; Brannan,RG; Chareonsuk,D; Chanasattru,W.
ABSTRACT The aim of this research was to investigate the physicochemical and functional properties of fresh and pasteurized chicken and duck egg albumens. The results showed that pasteurization of both chicken and duck albumens significantly decreased (p≤0.05) viscosity, but had no impact (p&gt;0.05) on pH or free sulfhydryl groups. Chicken albumen was shown to have higher (p≤0.05) foam expansion, but lower (p≤0.05) foam stability than duck albumen. Pasteurization decreased (p≤0.05) the foam expansion of both albumens while decreasing (p≤0.05) the foam stability only of duck albumen. Investigation of the gel properties showed that duck albumen has greater hardness and lower expressible water (p≤0.05) than chicken albumen. Pasteurization increased the...

Autores: Muñoz,L.C.; Cardona.-Ramirez,S.; Silva,R.F.
ABSTRACT Hydroxyapatite (HA) is widely used as a biomaterial for bone repair and metallic prostheses coating. The main limitations of the current commercial synthetic hydroxyapatite compounds include high cost and decreased availability, especially for veterinary medicine purposes. Additionally, it is thought that HA biocompatibility and bioactivity could be enhanced by the addition of metal compounds. The objective of this work was to compare the subcutaneous tissue response of commercial and engineered hydroxyapatite obtained from the bovine femur diaphysis mixed with different concentrations of hexa-hydrated Zinc Nitrate in rabbits. Twenty-Five New Zealand female rabbits were used. Five treatments were done according to HA composition (commercial HA, no...

Autores: Crevelin,Letícia Garcia; Bicalho,Kátia Vanessa.
ABSTRACT The liquid limit (LL) is an important parameter for soil classification systems. The use of the cone penetrometer technique for measuring the liquid limit is an attractive alternative method since the percussion method is highly operator dependent. In this article, the importance of specifying the procedure and equipment used to determine the LL of a clay soil is highlighted using LL test results conducted on different clay soils. The results of LL, obtained by the percussion method proposed by Casagrande (LLc) and by the penetration cone method (LLp) on clay soils of different geological origins and plasticity were compared. The LLp values were determined using the British cone (20 mm fall cone penetration) method. The LLc values were determined...

ABSTRACT:  In healthy cartilage, chondrocytes maintain an expression of collagens and proteoglycans and are sensitive to growth factors and cytokines that either enhance or reduce type II collagen synthesis. In osteoarthritis, pro-inflammatory cytokines, such as IL-6, induce overexpression of metalloproteinases (MMP) and decreasing synthesis of aggrecan. Use of chondroprotectors agents, such as Platelet-Rich Plasma (PRP) and triamcinolone (TA) are alternatives to reduce the progression of joint damage. In this study, we used chondrocytes extracted from metacarpophalangeal joints of healthy horses as the experimental model. Cells were treated in vitro with PRP or TA. No differences were observed between these treatments in comparison to the control group...

Autores: Romani,RF.; Waniewski,J.; Kruger,L.; Lindholm,B.; Nascimento,M.M.
The peritoneal equilibration test (PET) is the most widespread method for assessing water and solute transport across the peritoneal membrane. This study compared three methods: traditional PET (t-PET), mini-PET, and modified PET (mod-PET). Non-diabetic adults (n=21) who had been on peritoneal dialysis (PD) for at least three months underwent t-PET (glucose 2.5%-4 h), mini-PET (glucose 3.86%-1 h), and mod-PET (glucose 3.86%-4 h) to determine dialysate-to-plasma concentration ratio (D/P) for creatinine and dialysate-to-baseline dialysate concentration ratio (D/D0) for glucose. Agreement between methods regarding D/P creatinine and D/D0 glucose was assessed using analysis of variance (ANOVA), Pearson's correlation coefficient, and Bland-Altman analysis. D/P...

ABSTRACT Despite its interesting agricultural traits, Swingle citrumelo (Citrus paradisi Macfad. ‘Duncan’ × Poncirus trifoliata L. Raf.) rootstock exhibits severe incompatibility when grafted with Pera sweet orange [Citrus sinensis (L.) Osb.] scions, and this fact limits its use for propagation purposes. Nonetheless, the existence of certain Pera sweet orange clones that are compatible with Swingle citrumelo represents a substantial gain for the entire citrus industry. This study investigated the compatibility between seven Pera sweet orange clones and Swingle citrumelo rootstock, regarding the presence of a necrotic line at the graft union junction, the difference in diameter between rootstock and scion, the influence of clonal cleaning by micrografting,...

ABSTRACT: The competition between weeds and crops is one of the main factors responsible for productivity losses in agricultural fields. This review aimed at presenting and discussing how the interactions between weeds and microorganisms can affect the competitive capacity of weeds and soil physicochemical properties. We also discuss how changes in the elemental stoichiometry of weeds can reflect their competitive and adaptative capacity. Although weeds are more dependent on associations with soil microorganisms than crops for growth, few studies have assessed the contribution of the soil microbiota to their competitive success in agroecosystems. When in competition, plants can change the elemental stoichiometry of their tissues in environments with varied...

Abstract The Florida manatee (Trichechus manatus latirostris) is an endangered subspecies of the West Indian manatee (T. manatus), which inhabits inland and marine waters of southeastern United States. In this study, we assembled the mitochondrial genome (mtDNA) of the Florida manatee from whole genome shotgun reads. As a result, we show that the currently annotated T. manatus mtDNA belongs to a different species, the Amazonian manatee (T. inunguis). The newly assembled Florida manatee mtDNA is 16,881 bp in length, with 13 protein-coding genes, two ribosomal RNAs (rRNAs), 22 transfer RNAs (tRNAs) and one non-coding control region (D-loop). Phylogenetic analysis based on the control region indicates the newly assembled mtDNA is haplotype A01, characteristic...

Marennine, the water-soluble blue pigment produced by the marine diatom Haslea ostrearia, is known to display antibacterial activities. Previous studies have demonstrated a prophylactic effect of marennine on bivalve larvae challenged with a pathogenic Vibrio splendidus, suggesting that the blue Haslea is a good candidate for applications in aquaculture as a source of a natural antimicrobial agent. Indeed, the genus Vibrio is ubiquitous in aquaculture ecosystems, and regular events of pathogenic invasion cause some of the biggest losses worldwide. To better characterize the effects of marennine on Vibrios, a panel of 30 Vibrio strains belonging to 10 different species was tested, including bivalve pathogenic species (e.g., Vibrio crassostreae and Vibrio...

They also provide important support to paleoecological investigations that, usually, treat bryophytes as a whole, which does not permit the evaluation of specific functional traits of a special taxonomic unit. The present study investigated the morphology and ultrastructure of spores of five species of Erpodiaceae (Bryophyta), and assessed the implications for taxonomy and the recognition of spores of past records. Erpodiaceae includes corticolous and saxicolous plants that are widely distributed throughout tropical and temperate regions. The spores were found to be isomorphic and apolar with a subcircular amb, granulate, inaperturate. The...

There are more than a thousand species of bamboo and some of these contain large amounts of fibres with attractive properties. However, the extraction of the fibres without damaging them is difficult, requiring energy and special equipment. One solution is to use the bamboo in the form of thin strips taken from fibre-rich regions of the plant, as done by the Cobratex company in an innovative process. These contain the fibres but they are protected from damage and keep their alignment. This paper presents the results from a study of bamboo strips, alone and in an infused composite. The influence of seawater immersion is investigated. The composite weight gain is high, around 25 %, but most of the water is in the natural canals of the wood. The influence of...

ABSTRACT:  The aim of this study was to examine the impact of cultivar and spear color on the composition of polyphenols in asparagus spears (Asparagus officinalis). The five genotypes (Schwetzinger Meisterschuss, Huchel’s Alpha, Gijnlim, Grolim and Eposs) and three growing conditions of asparagus spears (Asparagus officinalis) were investigated. The polyphenols were determined by applying the HPLC-DAD system. The obtained results were subjected to the principal component analysis. Among the analyzed asparagus samples cv. Grolim contained the highest amounts of phenolic acids and flavonols. The varied quantitative and qualitative composition of polyphenolics resulted most probably from changes occurring during vegetation, such as a lack of access to light...

Composition of the fish fauna in a tropical estuary: the ecological guild approach
Provedor de dados: 5
Autores: Ferreira, Valdimere; Le Loc'H, Francois; Menard, Frederic; Fredou, Thierry; Fredou, Flavia L.
Ecological guilds have been widely applied for understanding the structure and functioning of aquatic ecosystems. This study describes the composition and the spatio-temporal changes in the structure of the fish fauna and the movements between the estuary and the coast of a tropical estuary, the Itapissuma/Itamaraca Complex (IIC) in northeastern Brazil. Fish specimens were collected during the dry and rainy seasons in 2013 and 2014. A total of 141 species of 34 families were recorded. Almost half of the species (66 species, 47%) were exclusive to the estuary and 50 species (35%) to the coast; 25 (18%) were common to both environments. Marine species were dominant in both richness and biomass as they explore the environment during part of their life cycle,...

Compound-specific recording of gadolinium pollution in coastal waters by great scallops
Provedor de dados: 5
Autores: Le Goff, Samuel; Barrat, Jean-alix; Chauvaud, Laurent; Paulet, Yves-marie; Gueguen, Bleuenn; Ben Salem, Douraied.
Gadolinium-based contrast agents (GBCAs), routinely used in magnetic resonance imaging (MRI), end up directly in coastal seawaters where gadolinium concentrations are now increasing. Because many aquatic species could be sensitive to this new pollution, we have evaluated the possibility of using shellfish to assess its importance. Gadolinium excesses recorded by scallop shells collected in Bay of Brest (Brittany, France) for more than 30 years do not reflect the overall consumption in GBCAs, but are largely controlled by one of them, the gadopentetate dimeglumine. Although its use has been greatly reduced in Europe over the last ten years, gadolinium excesses are still measured in shells. Thus, some gadolinium derived from other GBCAs is bioavailable and...

Computational algorithm for stability analysis of distribution networks with distributed generation
Provedor de dados: 52
Autores: Weigert,Gabriela Rosalee; Gurski,Erico; Benedito,Raphael Augusto de Souza.
Abstract With the insertion of distributed generation in distribution networks, security analysis becomes crucial, in islanded operation or when the system is connected to the grid. Dynamic stability analyses are necessary in order to achieve minimum levels of security and reliability. Such analyses are obtained through the solution of the algebraic-differential set of equations that model the distribution grid and their generators, which requires numerical solution methods. Therefore, this paper presents a computational tool for transient stability and large disturbance frequency stability analysis, considering distribution systems with the insertion of biomass-fed distributed generation, which may, or may not, have speed regulation systems. The presented...

Autores: Uchoa,Breno Kristoffer Beleza; Albério,Carlos Augusto Abreu; Pinto,Ana Carla Godinho; Lucena,Stefania de Medeiros Araujo; Vieira,José Luiz Fernandes.
ABSTRACT Rifampicin is used in both phases of treatment for tuberculosis. In chronic use, the short half-life and the self-induction of metabolism can decrease the levels of the drug below the minimal inhibitory concentration. The aim of the study was to investigate whether plasma concentrations of rifampicin are sustained above 0.5 µg/mL in patients with tuberculosis using 600 mg/day. Rifampicin was measured in plasma by high-performance liquid chromatography and a sputum smear microscopy was performed in all days of the study. A total of 44 male patients completed the study. On days 31, 61 and 91, the mean plasma concentrations of rifampicin were 0.6 (0.5) µg/mL, 0.55 (0.5) µg/mL and 0.46 (0.4) µg/mL. There was a high variation of rifampicin levels...

Conceptual advances on global scale assessments of vulnerability: Informing investments for coastal populations at risk of climate change
Provedor de dados: 5
Autores: Comte, Adrien; Pendleton, Linwood H.; Bailly, Denis; Quillerou, Emmanuelle.
Since the 1990s, the Intergovernmental Panel on Climate Change (IPCC) has used global assessments of vulnerability to inform investment and action against the effects of climate change. Beyond the IPCC, others have undertaken global assessments to understand the vulnerability of coastal areas to climate change. Eight global vulnerability assessments are compared to understand similarities and differences in their results and the metrics used to construct a vulnerability index. Variations in objectives, conceptualizations of vulnerability, operationalization of the concepts, scope and depth of data drawn upon lead to contradictory rankings of priority areas for climate action between assessments. The increased complexity and scope of indicators make it...

Autores: Spagnolo,Roger Toscan; Oldoni,André; Custódio,Tiago Vega; Reis,Ângelo Vieira dos; Machado,Antônio Lilles Tavares.
ABSTRACT:  The great difficulty for family farmers who produce food organically is the control of weeds without using chemical products. One possibility for the management is the use of heat in the sense of coagulating the protoplasm in leaves and stem cells. The present research aimed toconceptual design a mechanized system for weeds control through the use of heat focusing on familiar farmers who produce food organically. In this study, we used a product development methodology which can be divided into different stages that are composed of several tasks. As a result of the use of such methodology, six concepts of heat transfer machines were developed. After the application of selection tools, two concepts were chosen for the optimization process, and...

The VERtiCAL research project focused from 2013 to 2018 on the spatial and temporal diversification of fruit tree systems as a relevant mean for reducing pesticide use. The project resulted in the design and assessment of two fruit agroforestry systems (AFS), called "TAB" and "Durette", managed in organic farming and with specific technical and economic characteristics. The project allowed co-design experiences and led to the development of a new tool for ex ante assessment of AFS. First results show a 52% reduction of pesticides on the TAB system compared to a conventional reference system while reaching yield objectives, and a very low reliance to pesticides on the Durette system. As for biodiversity, specific richness of birds increased from 12 to 24...

Concomitant inguinal hysterocele with intrauterine dioctophyma renale parasitism
Provedor de dados: 195
Autores: Mattei, D. R.; Borges, F. A.; Oliveira, J. M. O.; Souza, M. L.; Bergamo, F. M. M.; Silva, E. U.
A partir do momento em que os serviços de ultrassonografia passaram a ser aplicados na clínica veterinária, o diagnóstico ultrassonográfico de Dioctophyma renale tem se tornado mais frequente. O órgão preferencialmente parasitado é o rim direito, e o tratamento efetuado é a nefrectomia unilateral. As localizações menos usuais do parasita podem ser: rim esquerdo, cavidade abdominal, ureteres; e tecido subcutâneo. O parasitismo em cães costuma ser subclínico quando apenas um rim é acometido, porém já foi relatada a peritonite, na qual o parasita é observado livre na cavidade abdominal. Os sinais clínicos que podem ser observados incluem: mucosas hipocoradas, hipertermia, desidratação, poliúria, polidipsia e hematúria. Cães errantes com acesso à rua, ou...

A hiperostose esquelética idiopática difusa (HEID) é um distúrbio esquelético sistêmico caracterizado por ossificação massiva progressiva dos tecidos moles envolventes dos esqueletos axial e apendicular. A doença afeta prevalentemente o ligamento longitudinal ventral, gerando fusão dos segmentos vertebrais em que é acometido e as enteses dos tendões e ligamentos do esqueleto apendicular. Os portadores da HEID frequentemente apresentam lombalgia associada à rigidez e restrição de movimento da coluna vertebral, na região afetada. Radiograficamente, a doença é caracterizada pela extensiva ossificação linear ao longo do aspecto ventrolateral da coluna vertebral. O tratamento geralmente é conservador, consistindo na modificação da atividade física,...

Conhecimento sobre mudanças climáticas implica em adaptação? Análise de agricultores do Nordeste brasileiro
Provedor de dados: 123
Autores: Carlos,Sabrina de Matos; Cunha,Dênis Antônio da; Pires,Marcel Viana.
Resumo Este estudo analisa a relação entre conhecimento sobre as mudanças climáticas e adoção de estratégias adaptativas de agricultores do Nordeste (bacia hidrográfica do Rio das Contas, Bahia). Metodologicamente, foi estimado um modelo Probit Bivariado Aparentemente Não Relacionado. Os resultados evidenciaram que conhecimento e adaptação são correlacionados e devem ser pensados de forma conjunta. Agricultores que conhecem os efeitos das mudanças climáticas têm maior probabilidade de adotar medidas adaptativas. Isso reforça a importância de se considerar a percepção, o conhecimento e as condições socioeconômicas dos indivíduos na formulação de políticas públicas de combate aos efeitos das mudanças climáticas.

Connecting organic to mineral: How the physiological state of an ecosystem-engineer is linked to its habitat structure
Provedor de dados: 5
Autores: Curd, Amelia; Pernet, Fabrice; Corporeau, Charlotte; Delisle, Lizenn; Firth, Louise B.; Nunes, Flavia; Dubois, Stanislas.
The honeycomb worm Sabellaria alveolata is capable of building extensive bioconstructions, including what are currently considered Europe’s largest biogenic reefs. The size and volume of these bioconstructions, however, vary greatly, such that not all habitats engineered by S. alveolata may be easily identified as reefs. Given that European environmental legislation protects marine habitats that are classified as “reefs”, it is important to identity a clear set of definition criteria. Furthermore, quantifiable and unequivocal criteria are also needed to evaluate the ecological (health) state of these reefs, in order to best monitor and protect them. Here we propose new terminology to describe the physical appearance of these bioconstructions and attempt to...

Autores: Gangnery, Aline; Normand, Julien; Duval, Cyrielle; Cugier, Philippe; Grangeré, Karine; Petton, Bruno; Petton, Sebastien; Orvain, Francis; Pernet, Fabrice.
Oyster diseases have major consequences on fisheries and aquaculture. In France, young Pacific oysters Crassostrea gigas are severely hit by the ostreid herpesvirus, whereas adults suffer mortalities presumably caused by pathogenic bacteria. Here we investigated the origin and spread of mortalities that affect both young and adult oysters, and we identified and compared their risk factors. Mortality was monitored in 2 age classes of oysters deployed in early spring at 39 sites spread over a 37 km2 surface area inside and outside of shellfish farms. Environmental data obtained from numerical modelling were used to investigate risk factors. Mortality of young oysters associated with ostreid herpesvirus occurred in the oyster farming area. Hydrodynamic...

Conservation Agriculture in Trouble? Estimating the Economic Impact of an Eventual Glyphosate Prohibition in Spain
Provedor de dados: 87
Autores: PARDO,G.; MARTÍNEZ,Y.
ABSTRACT: Weed control is a crucial aspect in many conservation agriculture systems given that costs and time savings from avoiding tillage are closely linked to the use of effective and environmental friendly herbicides. This has led to the widespread use of glyphosate in farms, as it is a broad-spectrum, easily degradable, low- cost herbicide. The recent debate on the safety of glyphosate and on the excessive use of chemical herbicides in food production has caused concern on farmers about the possible economic effects of a virtual ban on glyphosate. The aim of this paper is to estimate the costs associated with an eventual prohibition of glyphosate in Spanish conservation agriculture areas. The costs of different alternative weed control strategies for...

ABSTRACT Brycon orbignyanus is an endemic species from La Plata basin whose stocks have been presenting significant reductions throughout the Paraná River. Brycon orbignyanus is categorized as an endangered species. This study evaluated aspects of the bio-ecology of this species that may be related to this threat, highlighting its distribution, abundance, and diet as well as the corresponding relationships between its recruitment and flood regimes. Data were obtained from different parts of the upper Paraná River (stretches free and regulated by dams) from 1986 to 2010 with more detailed data collected from the free remnant of this basin. The results indicate that no records for species exist at more than half of the sampling points located in...

Provedor de dados: 111
Autores: Aliasgarian, Saeed.
Isfahan province in the center of Iran is mostly arid and semi-arid that causes some limitation in grain production. Recently, a contrast between conventional tillage and contemporary conservation tillage systems such as no-tillage and reduced tillage exists. The objectives of the study were to evaluate the effect of different tillage methods on soil properties, irrigation water use efficiency and crop yield of irrigated wheat followed by corn. Field experiment was conducted as a randomized complete block design with three treatments and three replications. Treatments consisted of no-tillage (NT), reduced tillage (RT) and conventional tillage (CT). Results showed significant effects of tillage method on seed germination and plant density but no difference...

Rapid changes in ocean circulation and climate have been observed in marine-sediment and ice cores over the last glacial period and deglaciation, highlighting the non-linear character of the climate system and underlining the possibility of rapid climate shifts in response to anthropogenic greenhouse gas forcing. To date, these rapid changes in climate and ocean circulation are still not fully explained. One obstacle hindering progress in our understanding of the interactions between past ocean circulation and climate changes is the difficulty of accurately dating marine cores. Here, we present a set of 92 marine sediment cores from the Atlantic Ocean for which we have established age-depth models that are consistent with the Greenland GICC05 ice core...

Abstract Wastewater generated in tanneries have essential elements for microalgae growth, but it has also some toxic compounds that may hinder or restrain the growth of microalgae in this environment. This work tested microalgae consortium growth originating from a deactivated effluent treatment decanter of a complete tannery (beamhouse to finished leather) for the treatment of wastewater of a tannery processing wet-blue leather to finished leather. It was initially evaluated the growth of the microalgae consortium in the three effluents diluted in 50% distilled water: raw effluent (50RE50W), effluent after primary coagulation/flocculation (50PE50W), and effluent after primary and secondary biological treatment (50BE50W). After 16 days of cultivation, the...

Constraining the age of the last geomagnetic reversal from geochemical and magnetic analyses of Atlantic, Indian, and Pacific Ocean sediments
Provedor de dados: 5
Autores: Valet, Jean-pierre; Bassinot, Franck; Simon, Quentin; Savranskaia, Tatiana; Thouveny, Nicolas; Bourlés, Didier L.; Villedieu, Anouk.
We studied four marine sediment records of the Matuyama–Brunhes geomagnetic reversal from four sites located in the Indian, Atlantic and western Pacific oceans. The results combine paleomagnetic, cosmogenic nuclide beryllium (10Be) and oxygen isotope analyses that were performed on the same samples in order to avoid any stratigraphic bias. The three records from the equatorial Indian Ocean and North Atlantic Ocean did not reveal any offset between the authigenic 10Be/9Be ratio (Be-ratio) peak and the interval of low relative paleointensity (RPI) that characterizes the reversal. The lower and upper limits of transitional directions are also concomitant with the increased atmospheric 10Be production that accompanied the geomagnetic dipole intensity decrease....

Autores: Killingsworth, B. A.; Sansjofre, P.; Philippot, P.; Cartigny, P.; Thomazo, C.; Lalonde, Stefan.
After permanent atmospheric oxygenation, anomalous sulfur isotope compositions were lost from sedimentary rocks, demonstrating that atmospheric chemistry ceded its control of Earth's surficial sulfur cycle to weathering. However, mixed signals of anoxia and oxygenation in the sulfur isotope record between 2.5 to 2.3 billion years (Ga) ago require independent clarification, for example via oxygen isotopes in sulfate. Here we show &lt;2.31 Ga sedimentary barium sulfates (barites) from the Turee Creek Basin, W. Australia with positive sulfur isotope anomalies of Delta S-33 up to +1.55% and low delta O-18 down to -19.5%. The unequivocal origin of this combination of signals is sulfide oxidation in meteoric water. Geochemical and sedimentary evidence suggests...

Constraining the vertical particle export during the last glacial cycle in Southern Indian Ocean sediment core
Provedor de dados: 5
Autores: Thevenaz, Antoine.
The large, 80-100 ppm, glacial-interglacial variations in atmospheric CO2 concentrations are today relatively well understood. However, low sediment accumulation in open ocean sediment cores generally prevents a fine, detailed comparison between marine and ice core records, in particular during ice ages. Core MD12-3394, retrieved from the Indian sector of the Southern Ocean, presents a very high sediment accumulation rate, which makes it possible to study in more details the climate-carbon cycle feedbacks during Marine Isotope Stage 3 (MIS 3) using a highly-resolved sedimentary archive. The thorium normalization method has been used to derive biogenic and lithogenic fluxes accounting for sediment focusing. Biogenic fluxes derived from XRF scanner...

Beans can be found in different grain colours, and for this reason, it is important to understand the technological and nutritional quality of the diverse types of beans that are consumed. The objectives of this work were to identify the traits that determine Brazilian consumer choice of different bean colours and to evaluate whether different bean colours present differences in technological and nutritional traits. For this purpose, beans of different colours (white, cranberry, matte red kidney, shiny red kidney, and black) were obtained from supermarkets. The samples were evaluated for consumer preference and the technological and nutritional traits of the beans. In southern Brazil, the majority of the survey participants (58%) preferred black beans, and...

Consumer preferences for organic food and for the shares  of meat and vegetables in an everyday meal
Provedor de dados: 21
Autores: Denver, Sigrid; Olsen, Søren Bøye; Christensen, Tove.
It is well established that consumers with positive preferences for organic products generally also tend to have healthy eating habits involving many fruits and vegetables but little meat. While most studies are based on single product comparisons, this study investigates consumer preferences for organic ingredients and content of meat and vegetables in the context of an everyday evening meal. Moreover, we address heterogeneity in preferences. The study is based on an online survey including a choice experiment with 506 consumers. Using principal component and latent class analyses we identify three segments of consumers that differ with respect to preferences for organic production and content of meat and vegetables in their meals. Our findings may be...

Autores: Güney,Osman Inanç.
ABSTRACT:  In recent years, increasing interest in natural and traditional plants, which are an integral part of rural life, has been observed because of health concerns and new social trends. In this regard, medicinal and aromatic plants (MAPs) are becoming more popular among consumers. The purpose of this research is to investigate consumers’ attitudes and behaviors toward MAPs in order to identify possible distinct consumer group and examine its potential linkage to the characteristics of the consumers’ demographic and socio-economic status. To detect the perceived differences among consumers, the principal component and k-means cluster analysis were performed using the data from a face-to-face survey (n=420) conducted in five major cities in the...

Consumption of Euterpe edulis fruit by wildlife: implications for conservation and management of the Southern Brazilian Atlantic Forest
Provedor de dados: 42
Autores: SILVA,JULIANO Z. DA; REIS,MAURÍCIO S. DOS.
Abstract: This study aimed to measure the wildlife consumption of Euterpe edulis fruit and use this data to discuss management possibilities. To estimate infructescence fruit volume consumed, collectors were installed in fruit-bearing palms. To characterize consumption from the ground, samples were placed next to fruiting palms. To identify wildlife and their activities, camera traps were installed in infructescences and on the ground. The results suggested that there was a small fruit surplus (1.8 %), and this finding indicated the possibility of a harvest to reduce food for the wildlife. However, recurrent variations in the annual fruit production (21.4 %) were also noted, and suggested that wildlife could tolerate some fruit harvesting. Thus, a harvest...

Contamination of Farms by Genetically Modified Organisms (GMOs): Options for Compensation
Provedor de dados: 21
Autores: Paull, John.
There is no satisfactory legal remedy for farmers in Australia whose farm has been contaminated by genetically modified (GM) material. This is a deficiency of Australia’s Gene Technology Act 2000 and it has not been remedied. In the Marsh v Baxter case (2010-2016) an organic farm in Western Australia (WA) was contaminated with GM canola from a neighbouring farm. The organic farm lost its certification (along with the price premium for organic produce). The organic farmer (Marsh) sued the GM farmer (Baxter) for the agreed damages of A$85,000. The case was lost in the WA Supreme Court, then in the Court of Appeal, and finally it was rejected by the High Court of Australia. The legal fees were in the order of A$2,000,000, which is quite disproportionate to...

Autores: Thiéblemont, Antoine; Hernández-molina, F. Javier; Miramontes, Elda; Raisson, François; Penven, Pierrick.
We present a combined study of the geomorphology, sedimentology, and physical oceanography of the Mozambique Channel to evaluate the role of bottom currents in shaping the Mozambican continental margin and adjacent Durban basin. Analysis of 2D multichannel seismic reflection profiles and bathymetric features revealed major contourite deposits with erosive (abraded surfaces, contourite channels, moats, furrows and scours), depositional (plastered and elongated-mounded drifts, sedimentary waves), and mixed (terraces) features, which were then used to construct a morpho-sedimentary map of the study area. Hydrographic data and hydrodynamic modelling provide new insights into the distribution of water masses, bottom current circulation and associated processes...

Contourite distribution and bottom currents in the NW Mediterranean Sea: Coupling seafloor geomorphology and hydrodynamic modelling

Autores: Miramontes Garcia, Elda; Garreau, Pierre; Caillaud, Matthieu; Jouet, Gwenael; Pellen, Romain; Hernández-molina, F. Javier; Clare, Michael A.; Cattaneo, Antonio.
Contourites are common morphological features along continental margins where currents encounter the seafloor. They can provide long-term archives of palaeoceanography, may be prone to sediment instability, and can have a great potential for hydrocarbon exploration. Despite their importance and increasingly recognised ubiquitous occurrence worldwide, the link between oceanographic processes and contourite features is poorly constrained. In particular, it is unclear under which specific conditions sediments are mobilised, modified and deposited by bottom currents. Here, we aim to determine key bottom current characteristics (velocity and bottom shear stress) affecting contourite deposition, by assuming that recent oceanographic regimes may be extended back...

Contrasting effects of rising temperatures on trophic interactions in marine ecosystems
Provedor de dados: 5
Autores: Durant, Joël M.; Molinero, Juan-carlos; Ottersen, Geir; Reygondeau, Gabriel; Stige, Leif Christian; Langangen, Øystein.
In high-latitude marine environments, primary producers and their consumers show seasonal peaks of abundance in response to annual light cycle, water column stability and nutrient availability. Predatory species have adapted to this pattern by synchronising life-history events such as reproduction with prey availability. However, changing temperatures may pose unprecedented challenges by decoupling the predator-prey interactions. Here we build a predator-prey model accounting for the full life-cycle of fish and zooplankton including their phenology. The model assumes that fish production is bottom-up controlled by zooplankton prey abundance and match or mismatch between predator and prey phenology, and is parameterised based on empirical findings of how...

Abstract Abstract: We used skeletochronology to compare age, size, reproductive parameters and growth patterns of two related, anuran amphibians from Northern Argentina: Leptodactylus bufonius(n=69) andL. latinasus(n=56), in order to better understand their coexistence in syntopy. Previous studies showed that the two species overlap in their dietary requirements and utilize the same habitats for feeding and breeding. We found that their life-history patterns are significantly different,L. bufoniusbeing larger, and having a higher reproductive output and lifespan, compared to the smaller and shorter-livingL. latinasus. Since none of the species exhibited sexual size dimorphism, and both acquired sexual maturity after the first year of life, we suggest that...

For segmented viruses, rapid genomic and phenotypic changes can occur through the process of reassortment, whereby co-infecting strains exchange entire segments creating novel progeny virus genotypes. However, for many viruses with segmented genomes, this process and its effect on transmission dynamics remain poorly understood. Here, we assessed the consequences of reassortment for selection on viral diversity through time using bluetongue virus (BTV), a segmented arbovirus that is the causative agent of a major disease of ruminants. We analysed ninety-two BTV genomes isolated across four decades from India, where BTV diversity, and thus opportunities for reassortment, are among the highest in the world. Our results point to frequent reassortment and...

Contrasting shell growth strategies in two Mediterranean bivalves revealed by oxygen-isotope ratio geochemistry: The case of Pecten jacobaeus and Glycymeris pilosa
Provedor de dados: 5
Autores: Peharda, Melita; Thebault, Julien; Markulin, Kresimir; Schone, Bernd R.; Janekovic, Ivica; Chauvaud, Laurent.
High-resolution stable-isotope ratio data (delta O-18, delta O-18) were used to study growth strategies of two bivalve species, Pecten jacobaeus (calcitic shell) and Glycymeris pilosa (aragonitic shell) from the North Adriatic Sea. The principal objectives of this study were to identify the period of the year when the growth line is formed in the shell of two target species, to identify the main growing season of these two species, to identify the environmental drivers of shell growth, and to evaluate the potential applicability of delta O-18 and delta O-18 values for the reconstruction of environmental variability. Samples were collected from the North Adriatic Sea by commercial bean trawl (P. jacobaeus, December 2013 and January 2014, N = 4) and SCUBA...

A number of trace metals play essential roles in marine ecosystem structure and biological productivity. Until recently, it has been argued that phytoplankton access primarily dissolved iron, while particulate iron was considered a refractory material with little use biologically and limited interaction with the dissolved pool. In order to assess the transfer mechanisms between sediment-sourced particulate trace metals and the dissolved pool, we conducted a 14-month incubation that reacted resuspended sediments with natural seawater, both originating from the Kerguelen area (KEOPS cruises; Southern Ocean), in the dark, and at concentrations replicating natural conditions. Three types of sediments were investigated (named BioSi, BioSi + Ca, and Basalt),...

Control Strategies for Floating Offshore Wind Turbine: Challenges and Trends
Provedor de dados: 5
Autores: Salic, Tom; Charpentier, Jean Frédéric; Benbouzid, Mohamed; Le Boulluec, Marc.
The offshore wind resource has huge energy potential. However, wind turbine floating structures have to withstand harsh conditions. Strong wind and wave effects combine to generate vibrations, fatigue, and heavy loads on the structure and other elements of the wind turbine. These structural problems increase maintenance requirements and risk of failure, while reducing availability and energy production. Another challenge for wind energy is to reduce production costs in order to be competitive with other alternatives. From the control point of view, the objective of lowering costs can be achieved by operating the turbine close to its optimum point of operation under partial load, guaranteeing reliability by reducing structural loads and regulating the power...

Controlled Release of TBH Herbicide Encapsulated on Ca-ALG Microparticles: Leaching and Phytointoxication Plants
Provedor de dados: 87
Autores: MACEDO,D.F.; DOURADO JR.,S.M.; NUNES,E.S.; MARQUES,R.P.; MORETO,J.A.
ABSTRACT: The aim of this work was to demonstrate a detailed study of the controlled release of the herbicide Tebuthiuron (TBH) encapsulated in microparticles of calcium alginate (Ca-ALG), to evaluate the phytotoxicity in different concentrations of herbicide (4, 6 and 8 g L-1), and their correlation with the depth of leaching using bioindicator plants. The Ca-ALG microparticles were prepared from the crosslinking of sodium alginate by Ca++ containing varied amounts of TBH supplied in calcium chloride (CaCl2) aqueous solution. The results showed that TBH herbicide, when encapsulated, leached to shallow depths relative to the conventional, non-encapsulated herbicide (which moved to a depth of 40-50 cm). The concentration of 4 g L-1 was the one that leached...

Controlled traffic farming increased crop yield, root growth, and nitrogen supply at two organic vegetable farms
Provedor de dados: 21
Autores: Hefner, M.; Labouriau, R.; Nørremark, Michael; Kristensen, Hanne Lakkenborg.
Increased farm machinery weight in agricultural production results in soil compaction. Controlled traffic farming (CTF) restricts traffic to permanent lanes, thereby creating traffic free beds for crop production. Field experiments were conducted at two organic vegetable farms in Denmark, on a sandy loam (2013–2016) and on coarse sand (2013–2015) to investigate CTF effects compared with random traffic farming (RTF) on vegetable yield, root growth, and soil mineral nitrogen (N). Root growth was measured using minirhizotrons. White cabbage, potato, and beetroot yield increased by 27%, 70% and 42%, respectively, in CTF compared with RTF in 2015 and winter squash indicated a yield increase of 43% on sandy loam in 2016. White cabbage (2015) and potato, beetroot...

Autores: Ranca, Aurora-Maria; Petrescu, Anamaria; Artem, Victoria; Boloș, P.; Cîlț, Mihaela; Ene, A.S.
The capability of plants of increasing the ecosystem resistance to pests and invasive species is a well-known ecosystem service. However, monocultures (including vineyards) do not exploit the potential of plant diversity. The aims of this research are to develop new viticultural systems based on increased plant diversity within (e.g., cover crops) and/or around (e.g., hedges, vegetation spots, edgings) vineyards by planting selected plant species for the control of arthropods, soil-borne pests (oomycetes, fungi, nematodes), and foliar pathogens. In order to control pests, plants species can either i) repel arthropod pests, ii) attract arthropod pests to a trap crop or iii) attract and/or conserve beneficials. An extensive systematic literature was...

We report mineralogical, elemental (major and trace elements) and SrNd isotopic data for suspended particulate matter (SPM) samples from the Amazon, Orinoco and Maroni Rivers collected on a monthly basis over a one-year long hydrological cycle. The aim of this study was i) to characterize the mineralogical and geochemical composition of major South American tropical rivers and ii) to evaluate the effect of seasonal hydroclimate variations and changes in sediment discharge on the composition of these SPM. In addition to displaying particular mineralogical and geochemical signatures (e.g. Al/Si ratios, weathering indices), the Amazon, Orinoco and Maroni SPM are characterized by marked differences in 87Sr/86Sr (0.7213 ± 0.0030, 0.7288 ± 0.0018 and...

Converting a Conventional Vehicle into an Electric Vehicle (EV)
Provedor de dados: 52
Autores: Silva,Jardel Eugenio da; Urbanetz Junior,Jair.
Abstract The electric vehicle (EV) is not a recent invention. Between the end of the XIX century and the beginning of the XX century, most motor vehicles were electric, due to their superior reliability and cleanliness, compared to that of vehicles driven by internal combustion engines (ICE). However, with the development of ICEs and the reduction of their price, electric cars were forgotten. Only almost a century later, they returned in the market due to a significant increase in fossil fuels prices, as well as to a growing environmental concern. EVs present a number of advantages over ICE vehicles: they are simpler and require less use and replacement of parts, resulting in lower maintenance costs; moreover, they do not release pollutants into the...

Autores: Silva,Maria de Fátima Gomes da; Sousa,Paulo Henrique Machado de; Figueiredo,Raimundo Wilane; Gouveia,Sandro Thomaz; Lima,Jorgiane Silva Severino.
ABSTRACT The present study aimed to compare the changes in the bioactive compounds, color parameters and to determine consumer opinions through sensory analysis of the pumpkin using different cooking methods (boiling, steaming, microwaving and sous vide). The cooking methods reduced the ascorbic acid content (49.73-50.42%) and polyphenols (49.68-64.94%). Microwaving increased the carotenoid content by 24.58%. The brightness (L*), red color (a*) and yellow color (b*) were reduced and there was also the loss of vivid color (chroma). The color of samples was affected after cooking process. All cooking methods were well accepted by the tasters, representing different market niches and many consumers expressed the intention of purchasing these products. The...

Autores: Shan,Xue.
ABSTRACT:  The effect of boiling, microwaving and aluminium (Al) foil-baking on composition of intramuscular phospholipid fatty acids of Inra rabbit was evaluated. Results showed that, the proportion of polyunsaturated fatty acids (PUFA)(e.g. C18:2n-6, C20:4n-6, C20:5n-3, C22:5n-3 and C22:6n-3) and monounsaturated fatty acids (MUFA)(e.g. C18:1n-7 and C18:1n-9) of treated longissimus dorsi muscle (LD) decreased, whilst the proportion of saturated (SFA)(e.g. C16:0 and C18:0) and n-6/n-3 value increased during cooking. Among the three treatments, microwaving can do better to stop the unsaturated fatty acids (UFA) being destroyed than boiling and Al foil-baking. However, boiling treatment did more serious damage to PUFA portion. Even so, the n-6/n-3 values of...

Cooling of curimba (Prochilodus lineatus) embryos using different concentrations of dimethyl sulphoxide and methanol
Provedor de dados: 96
Autores: Machado,Gilmara Junqueira; Murgas,Luis David Solis; Palhares,Priscila Cotta; Assis,Isadora de Lima; Castro,Tássia Flávia Dias.
ABSTRACT This study aimed to evaluate the effect of using different concentrations (5, 7.5, 10, and 12.5%) of two permeating cryoprotectants, dimethyl sulphoxide (DMSO) and methanol, on Prochilodus lineatus embryos while being subjected to cooling for 2, 4, 6, and 8 h at 4 °C. We analyzed the hatching rate, viable larvae, and counts of hatched and spoiled eggs and those that did not complete their development after cooling. We observed a significant interaction among variables, permeable cryoprotectant concentration, and cooling time, having the increase of these factors caused a reduction in hatching rate. The curimba embryos showed a higher sensitivity to cold at a temperature of 4 °C for 6 and 8 h, directly influencing the production of viable larvae....

Coordinated hunting behaviors of mixed-species groups of piscivores and associated species at Isla del Coco National Park (Eastern Tropical Pacific)
Provedor de dados: 83
Autores: Auster,Peter J.; Cortés,Jorge; Alvarado,Juan José; Beita-Jiménez,Andrés.
ABSTRACT Studies of mixed-species groups of animals can reveal emergent complexities of collective behaviors. In this study we collected data on mixed-species hunting groups composed primarily of piscivorous fishes (species composition, abundance, behavioral interactions) and used both multivariate and network analyses to quantify pair-wise and guild level behavioral relationships. Our results indicate that such collective behaviors exhibit consistent patterns of associations (33 species with 282 pair-wise links within the observed network) with 10 dominant species accounting for 60% of pair-wise interactions. Species richness within groups varied (mean = 2.4, range 2-6 species) as did group size (mean = 8.1 individuals, range 2-80). Mixed-species groups,...

Copepod Grazing Influences Diatom Aggregation and Particle Dynamics
Provedor de dados: 5
Autores: Toullec, Jordan; Vincent, Dorothée; Frohn, Laura; Miner, Philippe; Le Goff, Manon; Devesa, Jérémy; Moriceau, Brivaela.
In marine ecosystems, carbon export is driven by particle flux which is modulated by aggregation, remineralization, and grazing processes. Zooplankton contribute to the sinking flux through the egestion of fast sinking fecal pellets but may also attenuate the flux by tearing apart phytoplankton aggregates into small pieces through swimming activity or direct ingestion. Freely suspended cells, artificial monospecific aggregates from two different diatom species (Chaetoceros neogracile and Skeletonema marinoi) and natural aggregates of Melosira sp. were independently incubated with five different copepod species (Acartia clausi, Temora longicornis, Calanus helgolandicus, Euterpina acutifrons, and Calanus hyperboreus). During the grazing experiments initiated...

Coping styles in European sea bass: The link between boldness, stress response and neurogenesis
Provedor de dados: 5
Autores: Alfonso, Sebastien; Sadoul, Bastien; Gesto, Manuel; Joassard, Lucette; Chatain, Beatrice; Geffroy, Benjamin; Bégout, Marie-laure.
Coping styles consist of a coherent set of individual physiological and behavioral differences in stress responses that are consistent across time and context. Such consistent inter-individual differences in behavior have already been shown in European sea bass (Dicentrarchus labrax), but the associated mechanisms are still poorly understood. Here, we combine physiological measurements with individual behavioral responses in order to characterize coping styles in fish. Fish were tagged and placed in a tank for group risk-taking tests (GRT) at 8 months of age to evaluate boldness using the proxy latency of leaving a sheltered area towards an open area. A subsample of these fish were individually challenged 16 months later using an open field test (OFT), in...

Copolarized and Cross‐Polarized SAR Measurements for High‐Resolution Description of Major Hurricane Wind Structures: Application to Irma Category 5 Hurricane
Provedor de dados: 5
Autores: Mouche, Alexis; Chapron, Bertrand; Knaff, John; Zhao, Yili; Zhang, Biao; Combot, Clement.
C‐Band high resolution radar (SAR) is the only space‐borne instrument able to probe at very high resolution and over all ocean basins the sea surface under extreme weather conditions. When co‐analyzed with Stepped Frequency Microwave Radiometer (SFMR) wind estimates, the radar backscatter signals acquired in major Hurricanes from Sentinel‐1 and Radarsat‐2 SAR, reveal high sensitivity in the cross‐polarized channel for wind speeds up to 75 m/s. The combination of the two co‐ and cross‐ polarized channels can then be used to derive high resolution surface wind estimates. The retrieval methods and impacts of intense rainfall are discussed in the context of a Hurricane Irma (2017) case study. On September 7, 2017, Sentinel‐1 measurements intercepted Hurricane...

Autores: Moreira,Adônis; Moraes,Larissa Alexandra Cardoso; Nogueira,Thiago Assis Rodrigues; Canizella,Bruna Trovo.
Abstract: The objective of this work was to evaluate the effect of copper use efficiency in soybean cultivars, grown on a typical Ultisol with a high organic matter content, on soil chemical properties and on plant grain yield, nutritional state, and physiological components. The experiment was carried out in greenhouse conditions, in a 5×4 factorial arrangement, with five soybean cultivars (TMG 1066RR, BRS 360RR, NA 6262RR, BMX Turbo RR, and BRS 359RR) and four Cu rates (0, 2, 4, and 8 mg kg-1). Under the studied soil conditions, the DTPA-TEA and Mehlich-1 extractants were efficient in determining available Cu in the soil. Regardless of the cultivars, Cu application increased grain yield (GY), shoot dry weight yield (SDWY), number of pods per pot, GY/SDWY...

Anisotropy of magnetic susceptibility data obtained from discrete sub-samples recovered from two Integrated Ocean Drilling Program sites (Expedition 347 sites M0061 and M0062 in the Baltic Sea) by an Advanced Piston Corer are compared to results obtained on sub-samples recovered by replicate 6 m long Kullenberg piston cores. Characteristic natural remanence directions were obtained from the total of 1097 sub-samples using principal component analyses. The three principal anisotropy axes of sub-samples taken from Advanced Piston Core liners align to the sub-sample axes, with the maximum axis (K1) parallel to the split core surfaces, possibly caused by outwards relaxation of the core-liners after splitting.

Autores: Miguel,M.F.; Delagarde,R.; Ribeiro-Filho,H.M.N.
ABSTRACT Corn silage supplementation for dairy cows grazing in temperate annual pastures has rarely been investigated. The aim of this study is to compare two supplementation levels (0 and 4kg dry matter [DM]/day of a 7:1 mixture of corn silage and soybean meal) in dairy cows strip-grazing annual ryegrass (Lolium multiflorum Lam.) at two pasture allowances (PA, low= 25 and high = 40kg DM/d at ground level). The study was carried out according to an incomplete 4 × 3 Latin square design, using 12 cows and three experimental periods of 12 days. The green leaves allowances were only 4.9 and 8.5kg DM/d at the low and high PA, respectively. The total DM intake and milk production increased in supplemented cows compared to un-supplemented cows at the low PA, but...

RESUMO A fenda palatina é a comunicação entre a cavidade oral e a nasal através de um orifício no palato. Tem diversas etiologias, podendo ser congênita, traumática, por deficiência mineral ou por fatores hormonais. O diagnóstico é realizado por meio de exame físico da cavidade oral, e a correção cirúrgica é o tratamento de escolha. Em animais adultos, pode ser corrigida com o auxílio de retalho mucoperiosteal, apresentando bons resultados. Já em filhotes, a correção cirúrgica é mais complicada, com prognóstico menos favorável. Este trabalho relata o caso de um canino, fêmea, sem raça definida, adulta, com histórico de fenda palatina secundária, de origem traumática, no palato mole por ingestão de osso.

Most available CTD Satellite Relay Data Logger (CTD-SRDL) profiles are heavily compressed before satellite transmission. High-resolution profiles recorded at the sampling frequency of 0.5 Hz are, however, available upon physical retrieval of the logger. Between 2014 and 2018, several loggers deployed on elephant seals in the Southern Ocean have been set in continuous recording mode, capturing both the ascent and descent for over 60 profiles per day during several months, opening new horizons for the physical oceanography community. Taking advantage of a new dataset made of seven such loggers, a postprocessing procedure is proposed and validated to improve the quality of all CTD-SRDL data: that is, both high-resolution profiles and compressed low-resolution...

Autores: Silva,Ariane Márcia de Sousa; Oliveira,Emídio Cantídio Almeida de; Willadino,Lilia Gomes; Freire,Fernando José; Rocha,Alexandre Tavares da.
ABSTRACT Corrective phosphate application increases the levels of phosphorus (P) in the surface layer of the soil, stimulates plant root growth and increases the volume of soil exploited for water and nutrient uptake, which may reduce abiotic oxidative stress in sugarcane. The aim of this study was to evaluate the productivity and the response of the antioxidant enzyme system in sugarcane when grown in soil that received corrective phosphate application, using doses and sources of P of varying solubility. The experiment was conducted under field conditions in the southern Forest Zone of the State of Pernambuco, Brazil. The treatments were arranged in a randomised block design, in a (4 × 3) +1 factorial scheme with four replications. The factors consisted...

Correlação entre a deflexão intrinsecoide, classificação clínica e parâmetros ecocardiográficos em cães com degeneração mixomatosa valvar mitral
Provedor de dados: 45
Autores: Veiga,D.C.; Santos,G.C.; Sousa,M.G.
RESUMO A degeneração mixomatosa valvar mitral (DMVM) costuma ser diagnosticada pelo ecocardiograma, porém o eletrocardiograma (ECG) pode sugerir alterações específicas e auxiliar no diagnóstico e no tratamento. A deflexão intrinsecóide (DI) é uma medida simples do ECG, que representa o início da despolarização ventricular e pode indicar a presença de sobrecargas e hipertrofia no ventrículo esquerdo. O objetivo deste trabalho é comparar dados prévios sobre condição clínica e ecocardiograma de cães com endocardiose de mitral e o valor da deflexão intrinsecóide do ECG, para buscar uma relação de concordância. Foram selecionados os arquivos de 45 cães anteriormente atendidos na rotina clínica do HV-UPFR. A estatística mostrou diferença relevante nos grupos B1,...

RESUMO Radiografias torácicas e ecocardiogramas de 104 caninos foram avaliados e correlacionados quanto ao aumento das câmaras cardíacas. Os achados radiográficos foram correlacionados estatisticamente a fim de se estabelecer a acurácia do exame radiográfico na detecção do aumento cardíaco em comparação ao ecocardiográfico - padrão-ouro não invasivo. A correlação entre os achados radiográficos indicativos de aumento cardíaco e os índices ecocardiográficos mostrou-se fraca, significativa somente para VHS versus relação átrio esquerdo/aorta (r=0,3136), eixo curto versus relação átrio esquerdo/aorta (r=0,3813) e eixo curto versus velocidade da onda E (r=0,2021). A acurácia da radiografia na determinação subjetiva de aumento das câmaras cardíacas foi razoável,...

A radiografia torácica é utilizada rotineiramente como parte central do diagnóstico de cardiopatia e acompanhamento terapêutico em cães. Devido à sua subjetividade na avaliação cardíaca, a ecocardiografia é preconizada como a modalidade padrão para avaliação de aumento cardíaco e anormalidades morfofuncionais, sendo um método dinâmico e não invasivo que permite o diagnóstico mais acurado. Este trabalho investiga a correlação existente entre os achados radiográficos – sugestivos de aumento cardíaco com os achados ecocardiográficos aplicados à detecção da cardiomegalia.

ABSTRACT Host immunogenetic setting is involved in the regulation of human papillomavirus (HPV) infection and development of condyloma acuminatum (CA). We investigated the correlation of two common single nucleotide polymorphisms (SNPs) (−607C/A and −137G/C) of IL-18 with the susceptibility of CA in a large Chinese cohort. Out of 408 CA patients analyzed, 300 had HPV infection transmitted through sexual contact (SC) and 108 through non-sexual contact (NSC). In addition, 360 healthy volunteers were enrolled as controls. SNPs at positions −607C/A and −137G/C in IL-18 promoter were analyzed. Comparing CA patients to healthy controls, no dominant relevance was found between the IL-18 promoter −607 C/A or −137G/C polymorphisms and the CA disease either...

ABSTRACT:  Technological traits improvement of cotton fiber is a constant demand by textile industry. This research aimed to identify the potential of improved materials with high lint percentage to contribute with alleles that increase the lint percentage in Extra long staple fiber (ELS) upland cotton. Two contrasting materials for lint percentage (LP) and fiber length (FL) were used, one with long fiber and a low lint percentage (parent A) and another with high lint percentage and medium length (parent B). The following variables were evaluated: lint percentage (LP), upper half mean length (UHML), fiber uniformity (FU), fiber strength (FS), and elongation (EL). Diallel analysis was performed using the Griffing’s Method 4 adapted to partial diallel....

Abstract Fake news has been certainly the expression of the moment: from political round table discussions to newspapers to social and mainstream media. It is everywhere. With such an intense discussion and yet few effective ways to combat it, what can be done? Providing methods to fight back even the least harming hoax is a social responsibility. To look for authenticity in a wide sea of fake news, every detail is a lead. Image appearance and semantic content of text and images are some of the main properties, which can be analyzed to reveal even the slightest lie. In this vein, this work overviews some recent methods applicable to the verification of dubious content in text and images, and discusses how we can put them together as an option to curb away...

The study of protistan functional diversity is crucial to understand the dynamics of oceanic ecological processes. We combined the metabarcoding data of various coastal ecosystems and a newly developed trait‐based approach to study the link between taxonomic and functional diversity across marine protistan communities of different size‐classes. Environmental DNA was extracted and the V4 18S rDNA genomic region was amplified and sequenced. In parallel, we tried to annotate the Operational Taxonomic Units (OTUs) from our metabarcoding dataset to 30 biological traits using published and accessible information on protists. We then developed a method to study trait correlations across protists (i.e. trade‐offs) in order to build the best functional groups....

Estuaries are important areas highly vulnerable to anthropogenic pollutions. Therefore, the assessment of estuarine water quality is a major ecological issue. In this study, we sampled juveniles of the European flounder in the “pristine” Canche estuary, and caged them in Canche and in two polluted sites of the Seine estuary, Rouen and Fosse Nord. After one month, the metal and organic pollutants in these sites were assessed, and we evaluated several phenotypic indicators (condition index, RNA/DNA ratios and genotoxicity), and extracted the proteins in fish livers for analysis using a shotgun proteomics approach. The results showed strong modifications in the fish caged in both sites of the Seine estuary, as compared to those caged in Canche. In particular,...

Cover crops and compost influence soil enzymes during 6 years of tillage-intensive, organic vegetable production
Provedor de dados: 21
Autores: Brennan, Eric B.; Acosta-Martinez, Veronica.
Soil enzymes are considered sensitive indicators of soil health but are not well understood in tillage-intensive vegetable systems. The activities of soil enzymes involved in nutrient cycling (β-glucosidase, β-glucosaminidase, alkaline phosphatase, dehydrogenase, aspartase, and L-asparaginase) were evaluated during 6 yr of commercial-scale production in five organic vegetable systems in Salinas, CA. The systems differed in yard-waste compost inputs (none or 15.2 Mg ha–1 yr–1), winter cover crop frequency (annually or every fourth year), and cover crop type (legume-rye, mustard, or rye). Large differences in cumulative organic matter input (7.4 to 136.8 Mg ha–1) from compost and cover crop shoots affected soil enzyme activities. With exception of aspartase,...

Provedor de dados: 76
Autores: Rodrigues,Lucas; Ortega,Ileana; Vieira,Rony; Carrasco,Daiane; Proietti,Maíra.
ABSTRACT Crane flies are the most diverse group within Diptera, but they are rarely studied in coastal ecosystems. Considering the scarcity of information on the biology and ecology of this group in the Neotropics, and the sparse literature available for taxonomic identification, we developed a descriptive checklist that incorporates morphology and DNA barcoding. We also created a generic identification key for crane flies of southern Brazilian salt marshes. We sampled crane flies continuously at three areas along the Patos Lagoon salt marshes over one year. A total of 14 genera/subgenera, 6 species, and 12 morphotypes belonging to Limoniidae and Tipulidae were identified. Distribution ranges of Symplecta cana (Walker, 1848) and two Ormosia Rondani, 1856...

Autores: Costa,L.V.L.; Bonelli,M.A.; Silva,I.C.C.; Santos,M.S.; Fernandes,T.H.T.; Schwarz,T.; Costa,F.S.
ABSTRACT Computed tomography of the head of an otter with a history of incoordination, visual deficits, and seizures was performed. Intracranial images revealed a large non-enhancing fluid attenuating cystic lesion in the left frontoparietal region communicating with the left lateral ventricle and subarachnoid space. These findings are consistent with a congenital brain cavity filled by cerebrospinal fluid, with porencephaly being the most probable diagnosis based on the clinical and tomographic findings. The authors highlight the rarity of such a cystic lesion in wild animals, with this being the first report in otters.

ABSTRACT Prickly pear cultivation has played an important role in the Brazilian livestock farming, being used as forage for animals in the Northeast region, especially during the drying season, because it is an excellent source of water. Thus, the objective of this study was to estimate the crop coefficient and water requirement of prickly pear in the Agreste region of Alagoas state, Brazil. Prickly pear crop evapotranspiration (ETc) was determined using five drainage lysimeters, made of polyethylene with dimensions of 0.35 x 0.40 m (side and depth). Four soil layers were separated and put into the lysimeters in the opposite sequence, in order to maintain it as close as possible to the initial soil structure. The reference evapotranspiration (ETo) was...

Autores: Rolim,João; Navarro,Ana; Vilar,Pedro; Saraiva,Cátia; Catalao,Joao.
ABSTRACT Accurate crop data are essential for reliable irrigation water requirements (IWR) calculations, which can be acquired during the crop growth season for a given region using earth observation (EO) satellite time series. In addition, a relationship between crop coefficients and the NDVI can be established to allow for crop evapotranspiration estimation. The main objective of the present work was to develop a methodology, and its implementation in an application software, to extract crop parameters from EO image time series for a set of parcels of different types of crops, to be used as input data for a soil water balance model to compute IWR. The methodology was tested at two distinct test sites, the Vila Franca de Xira (site I) and Vila Velha de...

Crop Yield Responses to Sulfur Fertilization in Brazilian No-Till Soils: a Systematic Review
Provedor de dados: 90
Autores: Pias,Osmar Henrique de Castro; Tiecher,Tales; Cherubin,Maurício Roberto; Mazurana,Michael; Bayer,Cimélio.
ABSTRACT Sulfur (S) fertilization recommendations for grain crops in Brazil were formerly established from studies on crops with a low yield potential grown on soils under conventional tillage (CT). However, the subsequent adoption of no-tillage (NT) altered S dynamics in the soil, making it necessary to carefully evaluate the applicability of these S fertilizer recommendations. In addition, the emergence of modern high-yield-potential genotypes, the successive application of concentrated low-sulfur fertilizers, and reduction in S atmospheric deposition have raised the likelihood of positive responses of crops to S fertilization. Available literature reports contrasting crop responses to S fertilization in Brazilian soils, ranging from substantial gains to...

Common beans are legumes of extreme importance for the food security of developing countries. Because it is widely cultivated in tropical and subtropical regions, it is subject to the stress effects caused by this type of climate, such as water stress and heat. Cross-tolerance allows plants to acclimate to a range of different stresses after exposure to a specific short-term stress. The present work had as objective to evaluate the induction of cross-tolerance by heat stress at 38ºC and water stress simulated by polyethylene glycol (PEG) in 3 different osmotic potentials in the germination of the brazilian cultivars IPR Uirapuru and IPR Campos Gerais in a randomized block design, setting up a 2 x 2 x 3 factorial scheme, with eight replicates of 25 seeds....

ABSTRACT A 3 year old female feline of mixed breed was sent to the diagnostic imaging sector under suspicion of bleeding due to ovariohysterectomy. An abdominal ultrasonography was performed to confirm the initial suspicion. However, no signs of bleeding were found, instead it was observed that the left renal silhouette had two pelvises and was elongated and larger than normal. The right kidney was not found. Excretory urography was requested to evaluate the condition of the ureters. The final diagnosis was crossed renal ectopia with fusion in an asymptomatic cat with no changes in renal function.

Abstract The study of transferability of simple sequence repeats (SSR) among closely related species is a well-known strategy in population genetics, however transferability among distinct genera is less common. We tested cross-genera SSR amplification in the family Cactaceae using a total of 20 heterologous primers previously developed for the genera Ariocarpus, Echinocactus, Polaskia and Pilosocereus, in four taxa of the genus Cereus: C. fernambucensis subsp. fernambucensis, C. fernambucensis subsp. sericifer, C. jamacaru and C. insularis. Nine microsatellite loci were amplified in Cereus resulting in 35.2% of success in transferability, which is higher than the average rate of 10% reported in the literature for cross-genera transferability in eudicots....

ABSTRACT:  Pequi oil is rich in bioactive compounds which can be encapsulated to increase protection against extrinsic environmental factors. A delayed degradation of pequi oil may occur by using microencapsulation technology, in addition to masking unpleasant flavors and aromas. Complex coacervation is a technique based on the electrostatic interaction between two oppositely charged biopolymers which form a matrix complexed around an agent of interest. However, cross-linking the particles is often necessary in order to make them more rigid. The objective of this research was to produce and characterize pequi oil microparticles in a cashew gum (CG) and gelatin (GE) matrix cross-linked with tannic acid. Cross-linked pequi oil microparticles were produced by...

Provedor de dados: 22
Autores: Moreira, Cristiano Alves; Moreira, Geovane Alves; Cruz, Rayane Monique Sete da; Alberton, Odair.
As cultivares de mandioca apesar de adaptarem-se aos mais diferentes ecossistemas, apresentam alta interação do genótipo com o ambiente. O seu cultivo restringe-se em grande parte em um sistema de revolvimento solo, que altera as propriedades físicas, química e biológica do solo. Diante do exposto, objetivou-se avaliar cinco cultivares de mandioca em dois sistemas de plantio, direto sobre palhada de aveia preta (SPD) e convencional com revolvimento do solo (SPC). O experimento foi conduzido durante a safra de 2016/2017 em Tuneiras do Oeste (Paraná). O delineamento experimental utilizado foi blocos casualizados, em esquema fatorial 5 x 2 [5 cultivares de mandioca, sendo IPR União, IAC 15, IAC 90, Baianinha e Olho Junto (Caiua) x 2 sistemas de plantio (SPD e...

Cultivation-Assisted Genome of Candidatus Fukatsuia symbiotica; the Enigmatic "X-Type" Symbiont of Aphids
Provedor de dados: 5
Autores: Patel, Vilas; Chevignon, Germain; Manzano-marin, Alejandro; Brandt, Jayce W.; Strand, Michael R.; Russell, Jacob A.; Oliver, Kerry M.
Heritable symbionts are common in terrestrial arthropods and often provide beneficial services to hosts. Unlike obligate, nutritional symbionts that largely persist under strict host control within specialized host cells, heritable facultative symbionts exhibit large variation in within-host lifestyles and services rendered with many retaining the capacity to transition among roles. One enigmatic symbiont, Candidatus Fukatsuia symbiotica, frequently infects aphids with reported roles ranging from pathogen, defensive symbiont, mutualism exploiter, and nutritional co-obligate symbiont. Here, we used an in vitro culture-assisted protocol to sequence the genome of a facultative strain of Fukatsuia from pea aphids (Acyrthosiphon pisum). Phylogenetic and genomic...

Autores: Tornquist,Carlos G.; Silva,Diego S. da.
ABSTRACT This study evaluated historic land use and land cover changes in the Arroio Marrecas watershed (Caxias do Sul, Rio Grande do Sul state of Brazil) and simulated future land use scenarios until 2034. Spatial and temporal simulations were conducted with the Conversion of Land Use and its Effects - Small Regional Extent (CLUE-S) model. Three land use scenarios were developed to include public policies and agricultural trends in the study region for 20 years (2015-2034). Geospatial analysis of different land uses showed that areas that were originally covered grasslands and forests decreased, which can be attributed to the expansion of intensive agricultural uses, such as fruit farming/forestry and urbanization. The reallocation dynamics of land use...

Cutaneous mycobiota of boid snakes kept in captivity
Provedor de dados: 45
Autores: Freire,B.C.; Garcia,V.C.; Quadrini,A.E.; Bentubo,H.D.L.
ABSTRACT Boids are large, constrictor snakes that feed mostly on mammals, reptiles, and birds. These animals are commonly raised as pets, and their improper handling can favor the emergence of fungal infections, which can lead to dermatological diseases that are undiagnosed in nature. Here, we isolate and identify the filamentous fungi that compose the mycobiota of the scales of boid snakes kept in captivity at the Biological Museum of the Butantan Institute. Thirty individuals of four species were evaluated: four Eunectes murinus, twelve Boa constrictor constrictor, seven Corallus hortulanus, and seven Epicrates crassus. Microbiological samples were collected by rubbing small square carpets on the snake scales. We isolated five genera of fungi:...

ABSTRACT The cycle pruning programmed is a reinvigoration technique widely employed in Conilon coffee. This strategy may also be adopted for Arabica coffee to increase its crop longevity and yield. In this scenario, the present study proposes to examine the influence of the cycle pruning programmed on the vegetative and productive development of Arabica coffee. The experiment was developed in the field as a randomized-block design with four replicates. Treatments were tested in a 4 × 2 factorial arrangement consisting of four stem densities (4000, 8000, 12000 or 16000 stems ha-1) and two management strategies for the removal of plagiotropic branches (annual or biennial removal of branches which had reached 70% or more of their production capacity).

Provedor de dados: 83
Autores: Prestes,Anahiê Bortoncello; Nardelli,Aline; Paiz,Leonardo Marcel; Gavazzoni,Mariane; Margarido,Vladimir Pavan.
ABSTRACT Bryconamericus is a highly diverse group of characid fishes, being cytogenetic a valuable tool for the delimitation of species. Bryconamericus aff. iheringii (Upper Uruguay/Lower Paraná), B. coeruleus (Upper Paraná), B. cf. ecai e B. cf. eigenmanni (Upper Uruguay) were studied cytogenetically, and presented 2n=52 chromosomes, with interpopulational/interspecific variation of karyotype and fundamental number. Heterochromatin was evidenced in pericentromeric, telomeric and interstitial regions, and it was shown to be an important cytogenetic marker. Single nucleolar organizing regions (NORs) were found in B. cf. eigenmanni, B. cf. ecai and B. aff. iheringii (Lower Paraná), and multiple in B. aff. iheringii (Upper Uruguay) and B. coeruleus, with...

Abstract Parodontidae is a small group of fish and some species are particularly difficult to identify due to the lack of sufficiently consistent morphological traits. Cytogenetically, the species possess 2n = 54 chromosomes and are either sex-homomorphic or sex-heteromorphic (regarding its chromosomes). We evaluated data on color, tooth morphology, cytogenetics, and mitochondrial markers (COI) in Apareiodon specimens from the Aripuanã River (Amazon basin) and the results were compared to other congeneric taxa. Morphological results show an overlap of body color and tooth morphology to other known Apareiodon. The cytogenetics data showed that the 2n = 54 chromosomes, 50 m/sm + 4 st and, a ZZ/ZW sex chromosome system in Apareiodon sp. are common to other...

Abstract: The study aimed to know the daily life of women with alcoholic companions and the provided care. This is a comprehensive-interpretative, qualitative study, guided by the thematic Oral History method. Data collection occurred by semistructured interview. The empirical material was subjected to content analysis under the light of the King’s Theory of Goal Attainment. Women are frustrated and frightened by the alcoholic companion’s behavior and lifestyle, and still feel judged by society. Many abandon their life projects and self-care due to the overload caused by the companion’s absence in the care of home and children. The family care they develop focuses on maintaining the family and protecting from further damage. The study revealed that these...

For the first time, the anti-hemolytic activity and the enzyme inhibitory activities of Dalbergia ecastaphyllum leaves extracts were tested against α-amylase, α-glucosidase, lipase, acetylcholinesterase, butyrylcholinesterase, tyrosinase and hyaluronidase. The phenolic profile of the obtained extracts was also investigated by high-performance liquid chromatography with photodiode array detection (HPLC-PAD). The extracts showed inhibitory activity against all enzymes evaluated, with the highest inhibitory activity reported for the enzyme hyaluronidase (28.28 ± 2.43 to 72.19 ± 1.40 μg mL-1). The obtained extracts also demonstrate anti-hemolytic activity (52.22 ± 1.62 to 71.17 ± 1.82%). Among the phenolic compounds identified, protocatechuic, vanillic and...

Dalmore Farm: Victoria’s first biodynamic farming venture (1933-1934)
Provedor de dados: 21
Autores: Paull, John.
Dalmore Farm (1933-1934) was Victoria’s first biodynamic farming venture. A letter, written in Milan, Italy, in Italian in 1934 by Rosa Genoni (1867-1954) \ enables details of this venture to be finally revealed. Rosa wrote of her youngest brother, Ernesto Genoni (1885-1975): “Now Ernesto … is at Dalmore, a farm of my brother Marino (the father of the boy [Alfredo Genoni (1913-1999)] who was sent to us years ago from Australia and we sent him to Dornach where he stayed for two years, and two more to the school at Stuttgart) and in part by my brother Angelo, who asked Ernesto to go and organise the farm biologically”. “Ernesto had a small wooden house built there for his use. It has only two rooms but it must be fairly comfortable, as Ernesto invited...

DAMS SAFETY INDEX (DSI): A REASSESSMENT OF THE PARAMETERS OF ANALYSIS
Provedor de dados: 70
Autores: Garcia,Lucas do C.; Martim,André L. S. S.; Dalfré Filho,José G.; Fais,Laura M. C. F.
ABSTRACT Dams provide a water supply, irrigation and power generation. However, the economic, social and environmental impacts are serious when they rupture. It is important that dams continue to function properly and are constantly evaluated for their safety and functionality. Contrary to general belief, small dams are the ones that present the most problems, because they are often built without adequate design and construction methods. One of the methods to evaluate the safety of a dam is through the Dam Safety Index (DSI), which may not entirely avoid subjectivity in dam safety assessment but does propose balanced individual subjectivities in determining the weights of the index criteria. The DSI can also assist managers with preventive maintenance...

Økologisk fruktdyrking i Danmark øker, det samme gjør omsetningen av frukt og most. I april drog tolv produsenter og rådgivere fra Norge til de danske «sydhavsøerne» Fejø, Lolland og Møn for å få inspirasjon til økt økologisk fruktproduksjon. En viktig forskjell mellom dyrkinga i de to landene er tilgang på hjelpemidler i plantevernet.

Daphnia magna Exudates Impact Physiological and Metabolic Changes in Microcystis aeruginosa
Provedor de dados: 5
Autores: Bojadzija Savic, Gorenka; Edwards, Christine; Briand, Enora; Lawton, Linda; Wiegand, Claudia; Bormans, Myriam.
While the intracellular function of many toxic and bioactive cyanobacterial metabolites is not yet known, microcystins have been suggested to have a protective role in the cyanobacterial metabolism, giving advantage to toxic over nontoxic strains under stress conditions. The zooplankton grazer Daphnia reduce cyanobacterial dominance until a certain density, which may be supported by Daphnia exudates, affecting the cyanobacterial physiological state and metabolites’ production. Therefore, we hypothesized that D. magna spent medium will impact the production of cyanobacterial bioactive metabolites and affect cyanobacterial photosynthetic activity in the nontoxic, but not the toxic strain. Microcystin (MC-LR and des-MC-LR) producing M. aeruginosa PCC7806 and...

Das agronomische Potential von Winterweizen Evolutionsramschen in verschiedenen Anbausystemen
Provedor de dados: 21
Autores: Weedon, Odette; Finckh, Maria Renate.
Unvorhersehbare und zunehmend unsichere klimatische Bedingungen werden nicht nur abiotische (Hitze, Trockenheit) sondern auch biotische Stressfaktoren (unberechenbares und zunehmendes Auftreten von Pathogenen und Schädlingen) auf die Kulturpflanzen erhöhen. Externe Inputs alleine können diese Probleme nicht entschärfen. Zukünftige landwirtschaftliche Systeme müssen deutlich flexibler auf Stress reagieren können. Vor allem innerhalb ökologischer low-input Anbausysteme hat die Züchtung von Evolutionsramschen, die auf der Herstellung heterogener, evolvierender Composite Cross Populationen (CCPs) basiert, zunehmende Aufmerksamkeit geweckt. Die Vorteile solch genetisch vielfältiger Populationen umfassen u.a. flexiblere Reaktionen auf Stressfaktoren, die...

Gerade in der Nachhaltigkeitsforschung zeigt sich bei einfachen, retrospektiven Kundbefragungen häufig das Problem, dass sich angegebene und tatsächliche Kaufgewohnheiten unterscheiden. Werden sie danach befragt, neigen Kunden beispielsweise dazu, den Anteil an Biolebensmitteln oder anderen nachhaltigen Produkten an ihrem Gesamtkonsum zu überschätzen. Um die tatsächlichen Einkaufsgewohnheiten und –routinen zu untersuchen, müssen darum andere Forschungsmethoden herangezogen werden. Ein Beispiel hierfür ist die Tagebuchmethode, bei der Studienteilnehmer ihr tägliches Leben protokollieren, anstatt nur darüber zu sprechen. Diese Methode wurde in einer Studie zu Kunden von unverpackt-Läden in Deutschland angewendet. Der Beitrag diskutiert die Potentiale und...

Autores: Lguensat, Redouane; Viet, Phi Huynh; Sun, Miao; Chen, Ge; Fenglin, Tian; Chapron, Bertrand; Fablet, Ronan.
From the recent developments of data-driven methods as a means to better exploit large-scale observation, simulation and reanalysis datasets for solving inverse problems, this study addresses the improvement of the reconstruction of higher-resolution Sea Level Anomaly (SLA) fields using analog strategies. This reconstruction is stated as an analog data assimilation issue, where the analog models rely on patch-based and Empirical Orthogonal Functions (EOF)-based representations to circumvent the curse of dimensionality. We implement an Observation System Simulation Experiment (OSSE) in the South China Sea. The reported results show the relevance of the proposed framework with a significant gain in terms of Root Mean Square Error (RMSE) for scales below 100...

Data‐Driven Modeling of the Distribution of Diazotrophs in the Global Ocean
Provedor de dados: 5
Autores: Tang, Weiyi; Cassar, Nicolas.
Diazotrophs play a critical role in the biogeochemical cycling of nitrogen, carbon, and other elements in the global ocean. Despite their well‐recognized role, the diversity, abundance, and distribution of diazotrophs in the world's ocean remain poorly characterized largely due to limited observations. Here we update the database of diazotroph nifH gene abundances and assess how environmental factors may regulate diazotrophs at the global scale. Our meta‐analysis more than doubles the number of observations in the previous database. Using linear and nonlinear regressions, we find that the abundances of Trichodesmium, UCYN‐A, UCYN‐B, and Richelia relate differently to temperature, light, and nutrients. We further apply a random forest algorithm to estimate...

Abstract Dysphania schraderiana is widely distributed in Lhasa (Tibet, China) and used as a traditional medicine. However, the lack of genetic information hinders the understanding of its physiological processes, such as the biosynthesis of secondary metabolites. Herein, we used Illumina Hiseq4000 platform to sequence the transcriptome of flower and leaf tissues from D. schraderiana for the first time. Totally, 40,142 unigenes were assembled from approximately 5.2 million clean reads. All unigenes underwent gene prediction and were subsequently annotated in a NR (NCBI non-redundant protein) database, COG (Clusters of Orthologous Groups of proteins) database, and KEGG (Kyoto Encyclopedia of Genes and Genomes) database. Among the 40,142 unigenes, 2,579 genes...

Autores: Mathieu-begne, Eglantine; Loot, Geraldine; Blanchet, Simon; Toulza, Eve; Genthon, Clemence; Rey, Olivier.
Tracheliastes polycolpus is an ectoparasitic copepod that recently emerged in western Europe and that infects several freshwater fish species. Its recent successful spread might be due to its fascinating ability to shift to new host populations and/or species. Here, we present the first non-redundant and protein-coding de novo transcriptome assembly for T. polycolpus along with a quality assessment and reliable transcript annotations. This assembly was built from fifteen adult female parasites sampled from three different host species from a single river in southwestern France. Overall, 17,157 non-redundant contigs likely corresponding to protein-coding transcripts were identified, of which 13,093 (i.e., 76%) were successfully annotated. This assembly...

Measurements show large decadal variability in the rate of CO2 accumulation in the atmosphere that is not driven by CO2 emissions. The decade of the 1990s experienced enhanced carbon accumulation in the atmosphere relative to emissions, while in the 2000s, the atmospheric growth rate slowed, even though emissions grew rapidly. These variations are driven by natural sources and sinks of CO2 due to the ocean and the terrestrial biosphere. In this study, we compare three independent methods for estimating oceanic CO2 uptake and find that the ocean carbon sink could be responsible for up to 40% of the observed decadal variability in atmospheric CO2 accumulation. Data-based estimates of the ocean carbon sink from pCO(2) mapping methods and decadal ocean inverse...

Decentralizing and liberalizing EU regulations on seeds and plant genetic resources. A Danish case study
Provedor de dados: 21
Autores: Turpin, Grégoire; Boelt, Birte.
In a context of severe plant genetic diversity erosion, the regulatory framework of the European Union on seeds and plant genetic resources is perceived as a limiting factor to practices aiming to conserve cultivated biodiversity. To create more supportive frameworks, some EU member states liberalized seed trade and landraces cultivation regulations at national or regional level. For this paper, a case study of the 2015 cereal and vegetable seed legislation reform in Denmark has been carried out. Interviews with stakeholders of the seed system, with farmers and project leaders impacted by this change and with key informant on the regulation, from NGOs and public authorities, have been carried out. Inductive and deductive analysis methods enabled the themes...

Deciphering the effect of food availability, growth and host condition on disease susceptibility in a marine invertebrate
Provedor de dados: 5
Autores: Pernet, Fabrice; Tamayo, David; Fuhrmann, Marine; Petton, Bruno.
Food provisioning influences disease risk and outcome in animal populations in two ways. On the one hand, unrestricted food supply improves the physiological condition of the host and lowers its susceptibility to infectious disease, reflecting a trade-off between immunity and other fitness-related functions. On the other hand, food scarcity limits the resources available to the pathogen and slows the growth and metabolism of the host on which the pathogen depends to proliferate. Here, we investigated how food availability, growth rate and energetic reserves drive the outcome of a viral disease affecting an ecologically relevant model host, the Pacific oyster, Crassostrea gigas. We selected fast- and slow-growing animals, and we exposed them to high and low...

ABSTRACT: Low efficiency of nitrogen from fertilizers is a major concern worldwide, threatening the sustainability of sugarcane production. The N use efficiency (NUE) by sugarcane can be improved by adopting better fertilizing management practices, reducing environmental impacts. This work evaluated the effects of varying N rates and time of application on stalks and sugar yield in ratoon harvested early in the crop season. The experimental design was a randomized block in a 2 × 4 factorial design and a control (no N) with five replications, including two application times (45 or 90 DAH – days after harvest) and four N rates (50, 100, 150, or 200 kg N ha−1). The time of N fertilizer application promoted differences in stalk yield, as the cumulative yield...

Maerl beds form complex biogenic benthic habitats, characterized by high productivity as well as diverse biological communities. Disturbances associated with extraction and/or fishing activities using mobile bottom-contacting gears such as clam-dredges induce the most severe and long-term effects on these fragile habitats. We here investigated the effects of dredge-fishing on maerl in the bay of Brest (France). We quantified maerl beds structure and vitality across a fine scale quantified dredging intensity gradient through the acquisition of in-situ images of beds cross-section using Sediment Profile Imaging system (SPI). Declines in the proxies of maerl vitality and habitat complexity were measured across the gradient, and were associated with...

During winter in the Arctic marine ecosystem, diatoms have to survive long periods of darkness caused by low sun elevations and the presence of sea ice covered by snow. To better understand how diatoms survive in the dark, we subjected cultures of the Arctic diatom Chaetoceros neogracilis to a prolonged period of darkness (1 month) and to light resupply. Chaetoceros neogracilis was not able to grow in the dark but cell biovolume remained constant after 1 month in darkness. Rapid resumption of photosynthesis and growth recovery was also found when the cells were transferred back to light at four different light levels ranging from 5 to 154 µmol photon m−2 s−1. This demonstrates the remarkable ability of this species to re-initiate growth over a wide range...

DECREASE IN OFF-PEAK ELECTRICAL ENERGY DEMAND BY AGROINDUSTRIES DUE TO PHOTOVOLTAIC SOLAR GENERATION
Provedor de dados: 70
Autores: Viana,Lucas de A.; Oliveira Filho,Delly; Toledo,Olga M.; da Silva,Samuel C.; Dalvi,Giovanni G.
ABSTRACT The largest energy losses and voltage variations from electricity suppliers occur at times of peak demand. Daytime peaks are mainly influenced by large industrial and commercial consumers. The installation of photovoltaic systems without energy storage to supply part of the demand can contribute to stabilize the voltage and reduce losses. These and other benefits constitute the so-called externality of the decrease in off-peak demand due to photovoltaic generation. The objective of this study was to investigate the role of this externality in agroindustry, as a consumer of electrical energy, in order to better understand its effects on the consumer and the utility. The implementation of photovoltaic systems was simulated with the objective to...

Decreased respiratory performance of children and adolescents with myelomeningocele who use a wheelchair – preliminary data
Provedor de dados: 56
Autores: Martins,E.J.; Gastaldi,A.C.; Davoli,G.B.Q.; Leonardi-Figueiredo,M.M.; Mattiello-Sverzut,A.C.
Myelomeningocele (MMC) is a neural tube defect that often causes spinal cord injury at the thoracolumbar region, as well as sensory and motor paralysis in the lower limbs. This leads to continuous use of a wheelchair and, consequently, a sedentary lifestyle, predisposition to muscle weakness, cardiovascular and respiratory disorders, obesity, and structural alterations in the spine. We assessed the respiratory function and shoulder strength of MMC participants who were wheelchair-users and had no respiratory complaints and compared them to healthy children and adolescents. MMC (n=10) and healthy (n=25) participants of both genders with a mean age of 12.45 years (SD=2.1) were assessed for weight, height, respiratory performance, and isometric peak for...

Deep Currents in the Rift Valley of the North Mid-Atlantic Ridge
Provedor de dados: 5
Autores: Lahaye, Noe; Gula, Jonathan; Thurnherr, Andreas M.; Reverdin, Gilles; Bouruet-aubertot, Pascale; Roullet, Guillaume.
Over mid-ocean ridges, the interaction between the currents and the topography gives rise to complex flows, which drive the transport properties of biogeochemical constituents, and especially those associated with hydrothermal vents, thus impacting associated ecosystems. This paper describes the circulation in the rift valley along the Azores sector of the North Mid-Atlantic Ridge, using a combination of in-situ data from several surveys and realistic high-resolution modeling. It confirms the presence of a mean deep current with an up-valley branch intensified along the right inner flank of the valley (looking downstream), and a weaker down-valley branch flowing at shallower depth along the opposite flank. The hydrographic properties of the rift-valley...

Deep-ocean mixing driven by small-scale internal tides

Autores: Vic, Clement; Naveira Garabato, Alberto C.; Green, J. A. Mattias; Waterhouse, Amy F.; Zhao, Zhongxiang; Melet, Angelique; De Lavergne, Casimir; Buijsman, Maarten C.; Stephenson, Gordon R.
Turbulent mixing in the ocean is key to regulate the transport of heat, freshwater and biogeochemical tracers, with strong implications for Earth's climate. In the deep ocean, tides supply much of the mechanical energy required to sustain mixing via the generation of internal waves, known as internal tides, whose fate-the relative importance of their local versus remote breaking into turbulence-remains uncertain. Here, we combine a semi-analytical model of internal tide generation with satellite and in situ measurements to show that from an energetic viewpoint, small-scale internal tides, hitherto overlooked, account for the bulk (&gt;50%) of global internal tide generation, breaking and mixing. Furthermore, we unveil the pronounced geographical variations...

Autores: Delavenne, Juliette; Keszler, Louise; Castelin, Magalie; Lozouet, Pierre; Maestrati, Philippe; Samadi, Sarah.
Based on the specimens collected during three deep-sea cruises, and deposited at the Muséum National d’Histoire Naturelle (MNHN) in Paris, we analysed the diversity of benthic communities within the EEZ of French Polynesia. The literature and the MNHN database allowed us to inventory 471 species of invertebrates, among which 169 were newly described. We mainly found data for Mollusca, Crustacea, Brachiopoda and Crinoidea. We also found samples from other taxa, which still remain unidentified within the collections of the MNHN. Although this inventory is incomplete, we demonstrate that the deep waters of French Polynesia host unique benthic communities and endemic species. Using diversity and multivariate analyses, we show that the deep-sea benthic...

Deep-sea Hydrothermal Vent Bacteria as a Source of Glycosaminoglycan-Mimetic Exopolysaccharides
Provedor de dados: 5
Autores: Zykwinska, Agata; Marchand, Laetitia; Bonnetot, Sandrine; Sinquin, Corinne; Colliec-jouault, Sylvia; Delbarre-ladrat, Christine.
Bacteria have developed a unique strategy to survive in extreme environmental conditions through the synthesis of an extracellular polymeric matrix conferring upon the cells a protective microenvironment. The main structural component of this complex network constitutes high-molecular weight hydrophilic macromolecules, namely exopolysaccharides (EPS). EPS composition with the presence of particular chemical features may closely be related to the specific conditions in which bacteria evolve. Deep-sea hydrothermal vent bacteria have already been shown to produce EPS rich in hexosamines and uronic acids, frequently bearing some sulfate groups. Such a particular composition ensures interesting functional properties, including biological activities mimicking...

Autores: Miramontes, Elda; Jorry, Stephan; Jouet, Gwenael; Counts, John; Courgeon, Simon; Roy, Philippe; Guerin, Charline; Hernández-molina, F. Javier.
Subaqueous sand dunes are common bedforms on continental shelves dominated by tidal and geostrophic currents. However, much less is known about sand dunes in deep‐marine settings that are affected by strong bottom currents. In this study, dune fields were identified on drowned isolated carbonate platforms in the Mozambique Channel (south‐west Indian Ocean). The acquired data include multibeam bathymetry, multi‐channel high‐resolution seismic reflection data, sea floor imagery, a sediment sample and current measurements from a moored current meter and hull‐mounted acoustic Doppler current profiler. The dunes are located at water depths ranging from 200 to 600 m on the slope terraces of a modern atoll (Bassas da India Atoll) and within small depressions...

ABSTRACT Dehydration of plant products extends its shelf life and reduces its mass and volume, which increases transport and storage efficiency and adds value to food. However, it is an intensive process in energy and time, making necessary the search for more efficient technologies, Thus, this study aimed to investigate the infrared ginger dehydration process by approaching the constant period of dehydration to the theory of mass and heat transfer process to the wet bulb thermometer and the decreasing period of dehydration to liquid diffusion theory. We submitted 5.0 mm thickness and 2.0 cm diameter slices to a dryer with infrared radiation at 50, 60, 70, 80, 90 and 100 °C until constant mass.

Abstract: The objective of this work was to evaluate the effects of a slower chilling rate on the physical traits of 14-day aged top sirloin (gluteus medius) from F1 Angus x Nellore young bulls. Slight and lean beef carcasses (n = 30) were split in half and selected for control (2°C for 24 hours) and treatment (10°C for 10 hours followed by 2°C for 14 hours). Carcass temperature and pH decline were monitored in the longissimus dorsi (LD). Sarcomere length, color, and instrumental tenderness (Warner-Bratzler shear force and Volodkevich bite jaws) were measured on the gluteus medius (GM). pH 6.0 was reached when the LD temperature was very low, 3°C for the control and 6°C for the treatment. Differences in color and cooking losses were not significant. A...

Demonstrating the need for chemical exposure characterisation in a microplate test system: Toxicity screening of sixteen pesticides on two marine microalgae
Provedor de dados: 5
Autores: Dupraz, Valentin; Stachowski-haberkorn, Sabine; Wicquart, Jérémy; Tapie, Nathalie; Budzinski, Hélène; Akcha, Farida.
Pesticides used in viticulture create a potential risk for the aquatic environment due to drift during application, runoff and soil leaching. The toxicity of sixteen pesticides and one metabolite were evaluated on the growth of two marine microalgae, Tisochrysis lutea and Skeletonema marinoi, in 96-h exposure assays conducted in microplates. For each substance, concentrations of stock solutions were analytically measured and abiotic assays were performed to evaluate the chemical stability of pesticides in microplates. For two chemicals, microalgae exposures were run simultaneously in microplates and culture flasks to compare EC50 calculated from the two exposure systems. Results from chemical analyses demonstrated the low stability of hydrophobic...

Demonstration of facilitation between microalgae to face environmental stress
Provedor de dados: 5
Autores: Krichen, Emna; Rapaport, Alain; Le Floc'H, Emilie; Fouilland, Eric.
Positive interactions such as facilitation play an important role during the biological colonization and species succession in harsh or changing environments. However, the direct evidence of such ecological interaction in microbial communities remains rare. Using common freshwater microalgae isolated from a High Rate Algal Pond HRAP treating wastewaters, we investigated with both experimental and modeling approaches the direct facilitation between two algal strains during the colonization phase. Our results demonstrate that the first colonization by microalgae under a severe chemical condition arose from the rapid growth of pioneer species such as Chlorella sorokiniana, which facilitated the subsequent colonization of low growth specialists such as...

Demonstration-scale protein recovery by lactic acid fermentation from grass clover – a single case  of the production of protein concentrate and press cake silage for animal feeding trials
Provedor de dados: 21
Autores: Santamaria-Fernandez, Maria; Ambye-Jensen, Morten; Damborg, Vinni K.; Lübeck, Mette.
There is an increasing interest in green biorefineries for the utilization of green biomass to provide a variety of valuable products. Proteins can be extracted from green biomasses such as alfalfa, clover, or grass and separated into protein-rich concentrates suitable for feeding to monogastric animals. Press cake suitable for feeding ruminant animals is also produced. Full implementation of such a green biorefinery requires knowledge and experience of production at demonstration scale. Moreover, product evaluation in animal-feeding trials requires a large amount of product. There has been collaboration in Denmark between several partners from industry and academia to assess the practicality and scalability of a green biorefining plant producing protein...

Dendritic Gold Nanoparticles Towards Transparent and Electroactive Electrodes
Provedor de dados: 42
Autores: IOST,RODRIGO M.; MARTINS,MARCCUS V.A.; CRESPILHO,FRANK N.
Abstract: The combination of UV-visible absorption and electrochemical experiments (spectroelectrochemistry) enables to obtain highly specific spectroscopic information (in situ and operando) from modified surfaces. However, such application can be limited by the self-absorbance, for example, when metallic nanoparticles are present on modified surfaces. Indium-tin oxide onto glass (ITO) is a typical electrode commonly used for spectroelectrochemistry; ITO is an oxide-based semiconductor, and in numerous applications it is necessary to promote the modification of the electrode surface without significant loss of transparency. Here, we report a simple strategy to obtain ITO electrodes modified with self-assembled polyelectrolytes and active dendritic gold...

ABSTRACT:  Production of Tectona grandis (teak) in integrated systems with livestock or agriculture demonstrates high potential of financial return. However, studies on the development of teak are still scarce, especially in the northern region state of Mato Grosso. In this study we sought to evaluate dendometric variables of a clonal population of teak in a forest-livestock integration system (LFIS), during a period of 53 months in the city of Alta Floresta, Mato Grosso, Brazil. For this purpose, three installments were samples, a total of 360 individuals, and for each the diameter was measured at 1.3 meters from the base so as to calculate the total volume, the current annual increment (CAI) and mean annual increment (MAI), and five adjusted regression...

DENSIDADE POPULACIONAL DO NEMATOIDES-DAS-LESÕES-RADICULARES EM CANA-DE-AÇÚCAR EM FUNÇÃO DE CULTIVARES, MANEJO DO PALHIÇO E ESCARIFICAÇÃO DO SOLO
Provedor de dados: 196
Autores: Barbosa, Gabrielle Regina Miguel; Asmus, Guilherme Lafourcade.
A expansão do setor sucroalcooleiro suscitou preocupação quanto a questões que afetam a produtividade, tais como a presença de fitonematoides e as práticas de manejo cultural. O objetivo deste trabalho foi analisar a comunidade de nematoides do gênero Pratylenchus em cultivares de cana-de-açúcar plantados em solo submetido ou não à escarificação e ao aleiramento do palhiço residual da colheita. Foi conduzido experimento de campo em duas áreas, com e sem escarificação, nas quais foram plantadas 15 cultivares de cana-de-açúcar em subparcelas com e sem aleiramento do palhiço sobre as linhas de plantio. Anualmente, foram quantificados os nematoides do gênero Pratylenchus, no solo e nas raízes das plantas. Houve diferenças na densidade populacional do...

Density-dependent growth of bivalves dominating the intertidal zone of Banc d'Arguin, Mauritania: importance of feeding mode, habitat and season
Provedor de dados: 5
Autores: Van Der Geest, Matthijs; Van Der Lely, Jorge A. C.; Van Gils, Jan A.; Piersma, Theunis; Lok, Tamar.
Accurate predictions of population dynamics require an understanding of the ways by which environmental conditions and species-specific traits affect the magnitude of density dependence. Here, we evaluated the potential impact of season and habitat (characterized by sediment grain size and seagrass biomass) on the magnitude of density dependence in shell growth of 3 infaunal bivalve species dominating the tropical intertidal benthic communities of Banc d'Arguin, Mauritania. Two of our focal species were filter feeders (Senilia senilis and Pelecyora isocardia) and one was a facultative mixotroph (Loripes orbiculatus), mainly relying on organic carbon provided by sulphide-oxidizing endosymbiotic gill-bacteria (i.e. chemosymbiotic). Distinguishing 2 seasons,...

Denudation systematics inferred from in situ cosmogenic Be-10 concentrations in fine (50-100 mu m) and medium (100-250 mu m) sediments of the Var River basin, southern French Alps
Provedor de dados: 5
Autores: Mariotti, Apolline; Blard, Pierre-henri; Charreau, Julien; Petit, Carole; Molliex, Stephane; Aumaitre, Georges; Bourles, Didier L.; Keddadouche, Karim.
Marine sedimentary archives are well dated and often span several glacial cycles; cosmogenic Be-10 concentrations in their detrital quartz grains could thus offer the opportunity to reconstruct a wealth of past denudation rates. However, these archives often comprise sediments much finer (&lt; 250 mu m) than typically analyzed in Be-10 studies, and few studies have measured Be-10 concentrations in quartz grains smaller than 100 mu m or assessed the impacts of mixing, grain size, and interannual variability on the Be-10 concentrations of such fine-grained sediments. Here, we analyzed the in situ cosmogenic Be-10 concentrations of quartz grains in the 50-100 and 100-250 mu m size fractions of sediments from the Var basin (southern French Alps) to test the...

Abstract: This study evaluated 24 patients with lung cancer (CA) and 23 individuals with no smoking history or cancer in the family and without respiratory disease in childhood (CO). Peripheral blood lymphocytes was used to perform alkaline comet assay and to assess DNA damage as well as to evaluate methyl methane sulfonate (MMS) DNA repair after one hour and three hours at 37 ºC. The percentage of residual damage (RD) after three hours of MMS treatment, for each patient was assessed. The majority of patients were in the CA group, male patients, former smokers, with a history of smoking for 15 years and without associated comorbidities. Alkaline and residual damages were higher in the CA group when compared to controls (alkaline damage P = 0.015 and RD P =...

DEPOSITION AND COVERAGE OF SOYBEAN LEAF SURFACES BY SPRAYS APPLIED USING DIFFERENT ASSISTED BOOM SPRAYER SYSTEMS
Provedor de dados: 70
Autores: Hoffmann,Laercio L.; Roehrig,Rafael; Boller,Walter; Forcelini,Carlos A.
ABSTRACT Maintaining homogeneity in the distribution of fungicidal sprays applied throughout the plant, minimizing the variation between the upper and lower third of the plant, is one of the main challenges for application technologies with regard to soybean crops. To increase the deposition and leaf coverage of sprayed compounds, especially in the middle and lower thirds of the plant, we developed and tested alternative assisted boom sprayer systems. In this study, three assisted boom sprayer systems (Vortex®, Dropleg®, and chain curtain) were evaluated, in addition to the conventional system, in terms of the deposition and coverage of the leaf surface they achieved in the upper, middle, and lower thirds of plants using the fluorescent tracer Helios SC...

ABSTRACT:  The objectives of this study were to determine the rates of plant litter deposition and decomposition in Marandu pastures (Urochloa brizantha cv. Marandu) under a) three forms of nitrogen (N) supply, b) at different stages of rotational grazing and c) to compare the single-exponential decay constant (‘k’) derived from litterbags with values derived from estimates of deposited and existing litter (DEL technique). The three N supply treatments were: without or with N fertilization (zero or 150 kg N ha-1 yr-1) or with the legume Desmodium ovalifolium. There were no significant differences (p&lt;0.05) between existing litter and rates of litter deposition and decomposition between the three N supply treatments. The litter decomposition rate was...

Deposition of C and N in the soil from legume-based cover crops – quantification and mineralization.
Provedor de dados: 21
Autores: De Notaris, Chiara; Rasmussen, Jim; Sørensen, Peter; Olesen, Jørgen E.
Legume-based cover crops (CC) provide a wide range of ecosystem services, including nitrate leaching reduction, N fertilizer and soil C sequestration effects. However, the scarcity of information on belowground C and N increases the uncertainty on the magnitude of these effects. With the present study, we quantified soil C and N deposition from legume-based CC (two pure legumes and two mixtures) grown under field conditions, in Denmark. To do so, we labeled CC plants with 13C (CO2) and 15N (leaf-labeling) throughout their growing period, by following a frequent multiple-pulse labeling scheme. Then, we incubated labeled CC roots and soil to investigate C and N mineralization. Cover crops with red clover produced about 2.7 Mg ha-1 aboveground biomass, and...

Dérivés de l'exopolysaccharide d’Alteromonas infernus, mimétiques de glycosaminoglycanes, et développement d'une stratégie pour leur analyse structurale
Provedor de dados: 5
Autores: Akoumany, Katy.
In search of new bioactive compounds, marine bacteria constitute a considerable source of innovative molecules. The bacterial exopolysaccharide (EPS), produced by the deep-sea hydrothermal vent strain Alteromonas infernus, is a high-molecular-weight, highly branched and anionic heteropolysaccharide with a nonasaccharide repeating unit. This macromolecule and its low-molecular-weight derivatives obtained through a chemical process have previously displayed interesting GAG-like properties such as anti-metastatic and anti-coagulant (heparin-like) ones; they can also improve stem cell differentiation. To investigate the molecular bases of the biological activity and to facilitate the structural analysis of the bioactive derivatives (~20 000 g/mol), fragments...

Autores: DINIZ, F. H.
Devemos pensar que a ruralidade engloba não somente atividades agrícolas, mas abarca também expressões sociais, culturais e políticas. O fato é que existe uma nova ruralidade e é difícil determinar onde termina o rural e se inicia o urbano. Além da adequação das políticas públicas a essa nova realidade, é necessário modernizar o setor rural, tornando-o atraente para a juventude, para que jovens do campo não precisem migrar para os grandes centros urbanos em busca de oportunidades.

Desarrollo rural y agricultura familiar en Argentina: una aproximación a la coyuntura desde las políticas estatales
Provedor de dados: 123
Autores: Jara,Cristian Emanuel; Sperat,Ramiro Rodríguez; Manrique,Luis Felipe Rincón; Herrera,Andrea Gómez.
Resumen Sostener cuál ha sido el modelo (o los modelos) de desarrollo agrario que ha predominado en la Argentina en los últimos tiempos no es una tarea sencilla. Este artículo tiene por objetivo analizar la trayectoria del desarrollo rural en la República Argentina desde una mirada retrospectiva, prestando especial atención a cómo se ha concebido a la agricultura familiar. El eje argumental sostiene que las políticas agrarias, generalmente, han privilegiado a los modos de producción capitalistas en detrimento de los pequeños productores familiares de base campesina, quienes nunca terminaron de ser vistos como un sector productivo central en las dinámicas de desarrollo nacional. El texto se estructura en tres partes. En la primera, se presentan los...

Describing and diffusing the ethnobotanical knowledge of Bogotá D.C. (Colombia) through an online tool focused on common names of plants
Provedor de dados: 39
Autores: Rodríguez-Calderón,Ángela; Muñoz,José A.; Moreno,Diego; Celis,Marcela.
ABSTRACT Although ethnobotanical knowledge is considered potentially valuable information for several human disciplines, it is currently declining due to a decrease in the transmission of cultural knowledge and the depletion of natural resources. Consequently, focused efforts are required to compile such information and ultimately facilitate its diffusion. Bogotá D.C. consists of a large territory of rural and urban zones which has become a place of diverse cultural dynamics due to complex processes of historical evolution, making it an important target to conserve ethnobotanical knowledge. Here, we made a thorough compilation of ethnobotanical data for Bogotá focusing on plant common names and developed a freely available online tool (Platform of Plant...

Provedor de dados: 5
Autores: Totterdell, Ian J.
The Diat-HadOCC model (version 1.0) is presented. A simple marine ecosystem model with coupled equations representing the marine carbon cycle, it formed the ocean biogeochemistry sub-model in the Met Office's HadGEM2-ES Earth system model. The equations are presented and described in full, along with the underlying assumptions, and particular attention is given to how they were implemented for the CMIP5 simulations. Results from the CMIP5 historical simulation (particularly those for the simulated 1990s) are shown and compared to data: dissolved nutrients and dissolved inorganic carbon, as well as biological components, productivity and fluxes. Where possible, the amplitude and phase of the predicted seasonal cycle are evaluated. Since the model was...

Autores: ABEGG,ARTHUR D.; AZEVEDO,WEVERTON S.; FRANCO,FRANCISCO L.; DUARTE,MARCELO R.
Abstract: We recorded a second specimen of the poorly known insular blind snake Liotyphlops caissara. This new specimen expands the morphological variation of the number of dorsal scales in the genus Liotyphlops to 296 (vs. 304 in L. wilderi) and, considering the fact that the holotype of this species was destroyed, the present specimen represents the only available L. caissara individual in zoological collections. Also, this new record constitutes the first out of type locality and expands the distribution of the species in about 40 km to the northeastern. According to IUCN criteria (B1a, b [iii]), we suggest that L. caissara be included in the “Endangered” category, since it occurs in only two insular locations and exhibits an occurrence extension of...

Provedor de dados: 89
Autores: Maher,MA.
ABSTRACT Chickens have a great participation in meat and egg production. The anatomical scientific data of poultry is important to support the recent researches either for illustrations in academic studies or clinically in diagnosis and treatment of some poultry nutritional diseases. The current investigation was performed on twenty broiler chickens of both sexes. The chickens were anaesthetized, slaughtered then the venous system was flushed with a normal saline to anatomically investigate the distribution of hepatic portal veins both intra and extrahepatic, as well as the hepatic venous and biliary duct systems. The fowl had two hepatic portal veins draining the gastrointestinal tract with its associated organs as spleen and pancreas. The left hepatic...

Design and validation of a mobile air filter testing laboratory for animal agricultural applications
Provedor de dados: 111
Autores: Smith, Benjamin; Ramirez, Brett; Hoff, Steven; Harmon, Jay; Stinn, John.
The US swine industry is shifting towards filtered fresh-air ventilation systems that use pleated filters to improve breeding herd health and reduce airborne disease outbreak frequency. Loaded filters reduce airflow causing a poor environment and elevated energy use. Typical axial fans cannot efficiently maintain the rated differential pressure (DP; 100 Pa) for pleated filters; hence, a lower design filter DP (37 Pa) is used and consequently, more filters are required to achieve design maximum ventilation. Large, common filter banks for multiple staged fans presents significant challenges in using continuous DP measurement to assess filter life, making it impossible to separate filter loading DP from overall airflow DP. A mobile air filter testing (MAFT)...

Autores: HUDA, MD. NAZMUL.
AbstractGrading potatoes by size is an important operation for preparing tubers for seed and for commercial purposes. If potatoes were sold after grading, this would be beneficial to both producers and consumers. Since mechanical graders are not locally available, potatoes are graded, when necessary, by hand. This is a time consuming, costly, and inefficient method. This work concerns the development of a potato-grading machine for small-scale farmers. The grader consisted of a hopper, grading unit, prime mover and catchment tray fitted on a frame. The grader was made of locally available materials to keep the cost low. The grading unit was made up of plastic oil container, hopper and catchment tray made up of mild steel sheet and the frame was made up of...

Orchards, as intensive cropping systems, often have low diversity of plant species, which limits the promotion of natural enemies for pest control. The implementation of agri-environmental schemes, such as flower strips, could enhance biological control. We developed perennial, multifunctional flower strips with native plant species. In the second and third year after sowing, plant diversity and ground cover between flower strips (FS) in the drive alleys and the spontaneous orchard vegetation in control plots (Cont) were compared in 19 experimental blocks of eight organic apple orchards in six European countries. On average 73.7% of the sown plant species were established and plant diversity of FS was on average 43% higher than in Cont. Multivariate...

DESMISTIFICAÇÃO do consumo de carne ovina: programa 38: Sul.
Provedor de dados: 14
O Prosa Rural desta semana fala sobre a desmistificação do consumo de carne ovina. A convidada do programa é a pesquisadora Elen Nalério. Uma pesquisa realizada pela Embrapa apontou que 12% da população brasileira nunca comeu esse tipo de proteína. Outros vinte e sete por cento comem carne ovina apenas algumas vezes por ano e trinta e cinco por cento comeram alguma vez na vida, mas sem muita frequência. Isso representa um mercado potencial de 128 milhões de consumidores. Para atender a esse público, a Embrapa tem desenvolvido novos produtos, além de novos tipos de corte que facilitam o consumo pelas famílias no dia a dia.

Cultivated bivalves are important not only because of their economic value, but also due to their impacts on natural ecosystems. The Pacific oyster (Crassostrea gigas) is the world's most heavily cultivated shellfish species and has been introduced to all continents except Antarctica for aquaculture. We therefore used a medium-density single nucleotide polymorphism (SNP) array to investigate the genetic structure of this species in Europe, where it was introduced during the 1960s and has since become a prolific invader of coastal ecosystems across the continent. We analyzed 21,499 polymorphic SNPs in 232 individuals from 23 localities spanning a latitudinal cline from Portugal to Norway and including the source populations of Japan and Canada. We confirmed...

The Central Indian Ocean, namely the Central Indian, Crozet, and Madagascar basins, formed by rifting and subsequent drifting of India (now Capricorn), Antarctica, and Africa (now Somalia). We gathered a comprehensive set of sea surface magnetic anomaly profiles over these basins and revisited location and identification of magnetic isochrons between C34ny (83.0 Ma) and C20ny (42.536 Ma) using the objective analytic signal technique. We present high-resolution magnetic isochrons for 29 periods based on similar to 1,400 magnetic anomaly picks. From the conjugate sets of picks, we derive two-plate finite rotation parameters for both the Capricorn-Antarctica and Capricorn-Somalia motions. These finite rotations are compared to three-plate reconstructions of...

Autores: Tejada,T.S.; Conceição,R.C.S.; Timm,C.D.
RESUMO Campylobacter jejuni é o principal causador de gastroenterite bacteriana aguda, e a carne de frango tem se mostrado uma importante fonte de transmissão. Este microrganismo é de difícil isolamento e os métodos convencionais muitas vezes não são eficientes, podendo levar a resultados errôneos. O objetivo deste trabalho foi desenvolver e testar a técnica de separação imunomagnética (IMS) na detecção de C. jejuni em produtos de frango. Micropartículas magnéticas ligadas a anticorpos policlonais anti-C. jejuni foram utilizadas para concentrar C. jejuni antes da semeadura em ágar. O protocolo foi comparado com o método convencional. C. jejuni foi recuperado do alimento experimentalmente contaminado por ambos os métodos, entretanto, quando foi usada a IMS,...

Detecting outliers in species distribution data: Some caveats and clarifications on a virtual species study
Provedor de dados: 5
Autores: Meynard, Christine N.; Kaplan, David; Leroy, Boris.
Liu et al. (2018) used a virtual species approach to test the effects of outliers on species distribution models. In their simulations, they applied a threshold value over the simulated suitabilities to generate the species distributions, suggesting that using a probabilistic simulation approach would have been more complex and yield the same results. Here, we argue that using a probabilistic approach is not necessarily more complex and may significantly change results. Although the threshold approach may be justified under limited circumstances, the probabilistic approach has multiple advantages. First, it is in line with ecological theory, which largely assumes non‐threshold responses. Second, it is more general, as it includes the threshold as a...

Detecting Regional Modes of Variability in Observation-Based Surface Ocean pCO(2)
Provedor de dados: 5
Autores: Landschuetzer, Peter; Ilyina, Tatiana; Lovenduski, Nicole S.
We use a neural network-based estimate of the sea surface partial pressure of CO2 (pCO(2)) derived from measurements assembled within the Surface Ocean CO2 Atlas to investigate the dominant modes of pCO(2) variability from 1982 through 2015. Our analysis shows that detrended and deseasonalized sea surface pCO(2) varies substantially by region and the respective frequencies match those from the major modes of climate variability (Atlantic Multidecadal Oscillation, Pacific Decadal Oscillation, multivariate ENSO index, Southern Annular Mode), suggesting a climate modulated air-sea exchange of CO2. We find that most of the regional pCO(2) variability is driven by changes in the ocean circulation and/or changes in biology, whereas the North Atlantic variability...

Detection and epidemiological progress of quiescent avocado diseases
Provedor de dados: 65
Autores: Fischer,Ivan Herman; Moraes,Matheus Froes de; Firmino,Ana Carolina; Amorim,Lilian.
ABSTRACT: One of the major problems in the commercialization of avocados is the incidence of postharvest diseases, especially anthracnose (Colletotrichum spp.) and stem-end rot (Lasiodiplodia theobromae, Fusicoccum aesculi and Neofusicoccum spp.). As there is a lack of epidemiological information on these pathosystems, the objective of this study was to establish a method to detect quiescent infections and characterize their temporal progression and spatial pattern in a commercial orchard. Detection of quiescent infections was evaluated in flowers and fruits that were immature and in commercial harvest stage, treated with paraquat, ethrel or water. Treatment of flowers and immature fruits with paraquat led to rapid detection of Colletotrichum spp. In two...

Détection de la coelentérazine chez cinq espèces de Myctophidae du plateau des Iles Kerguelen
Provedor de dados: 5
Autores: Duchatelet, Laurent; Hermans, Claire; Duhamel, Guy; Cherel, Yves; Guinet, Christophe; Mallefet, Jérôme.
Myctophidae comprise the largest biomass of mesopelagic fishes in the Southern Ocean. This family has the ability to emit light – bioluminescence – via specific organs called photophores, and from the head and caudal organs. Through biochemical analyses, this study reveals that coelenterazine is the substrate for light reaction in the five most common myctophid species from the Southern Ocean. The results also support the hypothesis of the acquisition of this molecule via the food chain and reveal the presence of two stabilised storage forms of coelenterazine (enol-sulfate and dehydrocoelenterazine) within various tissues of the studied species. Finally, detection of coelenterazine in the gonads also suggests the potential maternal transfer of the...

Abstract Ground bovine meat is commonly consumed by the population of Brazil. However, it constitutes an excellent medium for the multiplication of microorganisms due to available nutrients and handling practices prior to consumption. Here, we examined 100 samples of ground beef for the presence of diarrheagenic Escherichia coli (DEC) pathotypes by PCR, and characterized isolates by analyzing their adherence to HEp-2 cells, serotype, antimicrobial susceptibility, and phylogeny. Enteroaggregative E. coli was detected in five (5%) meat samples, Shiga toxin-producing E. coli in three (3%), and atypical enteropathogenic E. coli in two (2%). According to the phylogeny, six isolates (60%) were classified in group A, two (20%) in group B1, and two (20%) in group...

ABSTRACT The melanocortin 1 receptor (MC1R) gene plays a key role in controlling the deposition of melanin. In mammals, the MC1Rgene is regarded as a major candidate gene in the control of melanin formation. In domestic animals, the MC1R gene mainly controls the expression of coat, skin, and plumage color in mammals and birds. In order to breed chickens with dark-green shank faster, we screened the molecular markers for shank color in a HS chicken population by exploring the relationship between polymorphism of the MC1R gene and three different shank colors (light green, dark green and yellow). Two primer pairs for code region of the MC1R gene were designed in the basic of chicken genomic sequence. DNA sequencing was performed to detect the polymorphisms...

ABSTRACT:  Wild boars (Sus scrofa) have become an important invasive species in all Brazilian regions. Increase in their population causes damage to rural properties, as they invade and destroy crops. To protect their crops and farm animals, producers hunt wild boars and often consume the product without any sanitary control, becoming exposed to various types of pathogens, including Toxoplasma gondii. Sanitary evaluations of these animals are scarce, especially in relation to the protozoan T. gondii. This study aimed to evaluate the occurrence of this pathogen in wild boars in Brazil. We analyzed 122 blood samples from wild boars (blood clots and serum), collected between 2014 and 2016 in five Brazilian states, using polymerase chain reaction (PCR) and...

A maioria das plantas superiores se reproduz sexualmente, ou seja, para formação do embrião ocorre a fecundação do óvulo por um gameta masculino. Entretanto, em muitas espécies de gramíneas forrageiras, o embrião se origina por meio de um processo de reprodução assexual via sementes denominado apomixia. Este modo de reprodução possui grande potencial para ser explorado na agricultura, particularmente na produção de sementes híbridas visando à manutenção do vigor híbrido ao longo das gerações. No melhoramento de espécies apomíticas, o cruzamento entre genitores sexuais e apomíticos origina progênies segregando para o modo de reprodução sexual e apomítico. A determinação do modo de reprodução das progênies pode ser realizada por diversas estratégias, uma...

Determination of Drilling Rate Index Based on Rock Strength Using Regression Analysis
Provedor de dados: 42
Autores: YENICE,HAYATI.
Abstract: Drillability is influenced by many factors, including machine parameters and rock properties. The main machine parameters for drilling include rotational speed, thrust force, torque and flush pressure. The specific rock characteristics that affect penetration rate comprise uniaxial compressive strength (UCS), tensile strength, Young’s modulus, hardness and brittleness. In this study, drilling rate index (DRI) is attempted to predict based on UCS and Brazilian tensile strength (BTS) of rocks. Simple and multiple regression analyses have been carried out to determine the best measure of the relation between DRI and two geomechanical properties. The DRI value is strongly related to the uniaxial compressive strength and indirect tensile strength....

Determination of methanol residues in crude glycerol for animal feed by gas chromatography
Provedor de dados: 63
Autores: Nazato,Carina; Romero,Alessandra de Cássia; Abdalla,Adibe Luiz.
ABSTRACT: Crude glycerol is a major by-product of biodiesel production and is an economical additive feed for ruminants. However, residual methanol in crude glycerol can be harmful to animal health. Several methods exist for quantifying methanol residues in biodiesel, yet few have been described that identify the methanol level in crude glycerol. We propose a method for determining the methanol level in crude glycerol destined for animal feed. Crude glycerol was extracted from the headspace and quantified by gas chromatography using a flame ionization detector (GC-FID). The method was linear up to 0.5 % of methanol. The limits of detection (LOD) and quantification (LOQ) were 0.015 and 0.031 %, respectively. No significant matrix effects were observed....

Determination of the copper isotope composition of seawater revisited: A case study from the Mediterranean Sea
Provedor de dados: 5
Autores: Baconnais, Isabelle; Rouxel, Olivier; Dulaquais, Gabriel; Boye, Marie.
A new technique for the determination of dissolved copper isotope composition (δ65Cu) of seawater was applied to examine copper sources and internal cycling in the Mediterranean Sea. A succession of chelating resin with nitrilotriacetic acid functional groups and strong base anion exchange resin, together with optimization of the multi-collector inductively coupled plasma mass spectrometry set-up allowed to isolate copper from seawater matrix and to measure the 65Cu/63Cu ratios in seawater with an external precision of 0.06‰ (2 s.d.). This method was first applied for inter-comparison measurements to surface and deep waters sampled at station BATS in the North Atlantic Ocean. Disparities in δ65Cu reported here and in the literature over these samples...

Determining long‐term changes in a skate assemblage with aggregated landings and limited species data
Provedor de dados: 5
Autores: Marandel, Florianne; Lorance, Pascal; Trenkel, Verena.
Sustainable fisheries management requires assessment of exploited populations and communities. Traditional fisheries stock assessment methods need species‐specific input data, which for skates have only recently become available in Europe. To overcome this limitation, a Bayesian multispecies biomass production model was developed. In addition to aggregated landings, input data are short time series with species‐specific information (landings and biomass indices). Applying the approach to four main skate species and a group of two skate species, all managed together in the Bay of Biscay (Northeast Atlantic), long‐term changes in the skate assemblage composition were identified. Since the 1990s, Leucoraja naevus became increasingly dominant, while the...

Effective sustainable management of marine fisheries requires that assessed management units (that is, fish stocks) correspond to biological populations. This issue has long been discussed in the context of Atlantic bluefin tuna (ABFT, Thunnus thynnus) management, which currently considers two unmixed stocks but does not take into account how individuals born in each of the two main spawning grounds (Gulf of Mexico and Mediterranean Sea) mix in feeding aggregations throughout the Atlantic Ocean. Using thousands of genome‐wide molecular markers obtained from larvae and young of the year collected at the species’ main spawning grounds, we provide what is, to the best of our knowledge, the first direct genetic evidence for “natal homing” in ABFT. This has...

Autores: Michels,Marcus; Matte,Ursula; Fraga,Lucas Rosa; Mancuso,Aline Castello Branco; Ligabue-Braun,Rodrigo; Berneira,Elias Figueroa Rodrigues; Siebert,Marina; Sanseverino,Maria Teresa Vieira.
Abstract Pathogenic variants in the Cystic Fibrosis Transmembrane Conductance Regulator gene (CFTR) are responsible for cystic fibrosis (CF), the commonest monogenic autosomal recessive disease, and CFTR-related disorders in infants and youth. Diagnosis of such diseases relies on clinical, functional, and molecular studies. To date, over 2,000 variants have been described on CFTR (~40% missense). Since few of them have confirmed pathogenicity, in silico analysis could help molecular diagnosis and genetic counseling. Here, the pathogenicity of 779 CFTR missense variants was predicted by consensus predictor PredictSNP and compared to annotations on CFTR2 and ClinVar. Sensitivity and specificity analysis was divided into modeling and validation phases using...

Trace metal micronutrients are integral to the functioning of marine ecosystems and the export of particulate carbon to the deep ocean. Although much progress has been made in mapping the distributions of metal micronutrients throughout the ocean over the last 30 years, there remain information gaps, most notable during seasonal transitions and in remote regions. The next challenge is to develop in situ sensing technologies necessary to capture the spatial and temporal variabilities of micronutrients characterized with short residence times, highly variable source terms, and sub-nanomolar concentrations in open ocean settings. Such an effort will allow investigation of the biogeochemical processes at the necessary resolution to constrain fluxes, residence...

Autores: Penido,Édilus de Carvalho Castro; Teixeira,Mauri Martins; Fernandes,Haroldo Carlos; Monteiro,Paulo Barros; Cecon,Paulo Roberto.
ABSTRACT The tomato is one of the main crops in Brazil. In large-scale cultivation, pesticides are applied to the plant to prevent the direct or indirect action of animal or vegetable life, aiming at higher productivity and better quality fruit. However, the products, if used incorrectly, may affect the health of workers involved in the activity. A prototype of a self-propelled sprayer, remotely controlled and monitored via radio signals, was therefore developed to be used in tomato crops, thus minimising worker contact with the chemical substances used when spraying. The basic prototype comprises an agricultural mini-tractor, a motorised pneumatic sprayer (atomiser) and a set of electronic and mechanical sensors and actuators, which allow the assembly to...

Ocular allergy is one of the most common disorders of the eye surface. Following diagnosis this condition is typically treated with preparations containing antihistamines. However, anatomy of the eye and its natural protective mechanisms create challenges for ocular drug delivery. Rapid elimination of antihistamine substances due to short residency times following application can lead to insufficient treatment of ocular allergies. With this in mind, the aim of this study was to prepare a controlled ocular delivery system to extend the retention time of olopatadine hydrochloride (OLO) and in doing so to reduce the need for frequent application. We developed extended-release ocular in situ gelling systems for which in vivo retention times were determined in...

Autores: Fernandes,Elania; Araujo,Elton; Souza,Itala; Souza,Mariana; Nunes,Glauber.
ABSTRACT The gregarious endoparasitoid Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae) is a natural enemy of fruit flies. This parasitoid was previously used to successfully control Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in Hawaii, USA. Despite its importance in the control of fruit fly pests, little is known about the development or characteristics of its preimaginal stages. The aim of this study was to observe the development and morphologically characterize the immature stages of Tetrastichus giffardianus. Tetrastichus giffardianus individuals were reared on C. capitata larvae/pupae under laboratory conditions at a temperature of 25 ± 2 °C, relative humidity of 60 ± 10%, and 12-h photophase. Third-instar C. capitata larvae...

Autores: YOU, KYUSUK.
A prototypical end effectors was designed to validate its fruit picking performance focusing on picking success rate and crop quality. The end effector model composed of a central vacuum gripper and four articulate vacuum fingers to enable firm and secure grasping for citrus fruits. Slider-crank mechanism finger structures achieved solid contact between vacuum pad and fruit surface. Instead of stem severing, the fruit was removed by the combined geometrical motion of rotation and pulling. The developed end effector model fulfilled its fruit picking performance with 90.8% of removal rate at 90 degrees (± 5˚) of the initial approaching angle producing 6~31.5 N and 0.04~1.03 Nm of the detachment force and torque during field assessments.

Autores: Kanjanawanishkul, Kiattisin.
Color of dried chilies is one of the most key factors that influences consumers’ preference. It is mainly affected by the drying process. Traditionally, drying temperature is fixed during the drying process without regard to the quality of chilies being dried. Thus, the aim of this research is to develop a controller for the chili drying process that determines the drying temperature according to the change of chili color. To measure the chili color, we built a hot air tray dryer incorporated with a computer vision system which measures the chili color during drying. We converted the RGB color model to the L*a*b* color model and calculated the change of the a* component (\delta a). If \delta a within 15 minutes was less than 2, then, the drying temperature...

Autores: Haug, Benedikt; Messmer, Monika; Forst, Emma; Mary-Huard, Tristan; Enjalbert, Jérôme; Goldringer, Isabelle; Hohmann, Pierre.
Introduction  Mixed cropping, i.e. mixing different crops in the same field, provides agronomic advantages as increased productivity under low inputs conditions (e.g. for organic farming: Bedoussac et al. 2015) and higher yield stability (Raseduzzaman and Jensen 2017). In mixed cropping, choosing the right cultivars is critical for the performance of the mixture, as shown for pea-barley mixtures (Hauggaard-Nielsen and Jensen 2001) and maize-bean mixtures (Hoppe 2016). As performance in pure stand can strongly diverge from performance in mixture, estimating the ability of a cultivar to be mixed with another crop is therefore of utmost importance. For this purpose, concepts of General and Specific Combining Ability in hybrid breeding (Griffing 1956) have...

Provedor de dados: 124
Autores: Aragão,Márcia Facundo; Garruti,Deborah dos Santos; Ogawa,Norma Barreto Perdigão; Bezerra,Viviane Costa; Silva,Elisabeth Mary Cunha da.
ABSTRACT This work aimed to develop a Quality Index Method (QIM) for octopus species Octopus insularis and apply it to samples of eviscerated and non-eviscerated specimens in order to establish stability in cold storage. Initially we carried out the recruitment of judges, who were trained to verify the changes undergone by the octopus during storage under refrigeration. The development of QIM Table took place in three experiments. At first, a QIM Table for Octopus vulgaris from literature was presented to judges together with specimens of O. insularis, so they could assess whether the parameters were suited to this specie. In the second experiment the objective was to validate the table, verifying if changes were needed in the predefined parameters or if...

Development of seafloor mapping strategies supporting integrated marine management: application of seafloor backscatter by multibeam echosounders.
Provedor de dados: 5
Autores: Montereale Gavazzi, Giacomo Ottaviano Andrea.
Multibeam echosounding is indispensable for underwater monitoring, with backscatter and bathymetry data enabling Acoustic Seafloor Classification (ASC) and Change Detection (ACD). ASC is a maturing discipline, whilst ACD has remained virtually unexplored. To further develop techniques for the spatio-temporal quantification of seafloor status and dynamics, state-of-the-art hydroacoustic and ground-truth data were acquired in the Belgian Part of the North Sea and were integrated via automated classification routines. ASC research found variable predictive performance between supervised machine learning and unsupervised clustering classification. 300 kHz backscatter discrimination potential is weaker for heterogenous substrates, constraining the spatial...

ABSTRACT Developing superior lines based on a simultaneous response from many traits of agronomic importance is a fundamental strategy to expand papaya cultivar supply, mainly the much-needed cultivars belonging to group Formosa. Our goal was to associate the pedigree method with REML/Blup procedure to select plants of progenies F2:3 with superior agronomic performance. The variance components and genetic parameters were estimated using REML approach, and the genetic values were predicted using Blup methodology. The combined selection was performed using the IG2 selection index based on weights associated with agronomic values to indicate the best progenies and lines. The heritability estimates of progeny mean were high in most traits and evidenced...

Diagnosing ocean‐wave‐turbulence interactions from space
Provedor de dados: 5
Autores: Torres, H.s.; Klein, Patrice; Siegelman, L.; Qiu, B.; Chen, S.; Ubelman, C.; Wang, J.; Menemenlis, D.; Fu, L.‐l.
Numerical studies indicate that interactions between ocean internal gravity waves (especially those &lt;100 km) and geostrophic (or balanced) motions associated with mesoscale eddy turbulence (involving eddies of 100–300 km) impact the ocean's kinetic energy budget and therefore its circulation. Results from these studies have never been confirmed by observations in regional or basin‐scale domains. Here we show that internal gravity waves have a spectral signature on sea‐surface height (SSH) during summer that significantly differs from that of balanced motions. These spectral differences lead us to propose a new dynamical framework that quantifies the interactions between internal gravity waves and balanced motions in physical space from SSH snapshots,...

Osteíte podal é um processo inflamatório que atinge as falanges distais dos membros dos equídeos, levando ao quadro de desmineralização da margem solear da falange distal. O distúrbio pode ser classificado como séptico ou não séptico. As principais causas de osteíte podal séptica envolvem as laminites crônicas, abscessos sub-soleares, fratura da margem solear, rachaduras da parede do casco, lesões perfurantes e por avulsão. Acomete mais comumente os membros torácicos, nos quais é frequente a percepção do pulso digital aumentado associado ao aumento de temperatura no membro acometido. Os bloqueios perineurais dos nervos digitais palmares/ plantares podem não eliminar o grau de claudicação do membro em casos de osteíte podal séptica. A osteíte podal não...

Provedor de dados: 89
Autores: Yaman,S; Sahan Yapicier,O.
ABSTRACT Gallibacterium anatis, a member of the Pasteurellaceae family, leads to decrease in egg-production, animal welfare and increase in mortality. This study aimed to diagnose G. Anatis, which caused economic losses in laying hens by using conventional and molecular techniques. In this study, G. anatis was examined from a total of 200 dead chicken tissues (heart, liver, lung, spleen and trachea) in laying hen farms that observed a decrease in egg production with respiratory system infection. Conventional methods based on colony morphology, sugar fermentation tests and hemolytic properties and molecular conformation using 16S rRNA-23S rRNA specific primers were performed to identify G. anatis. G. anatis was isolated in 20 (10%) of the examined samples...

Resumo - As terras onde predominam solos de textura arenosa e franco-arenosa são, em geral, consideradas marginais em relação à sua aptidão agrícola. Isso se dá, em geral, devido à restrita capacidade de retenção de água e de nutrientes nesses solos, o que interfere diretamente na sua capacidade produtiva. O objetivo deste estudo foi avaliar as propriedades físico-hídricas de solos arenosos em áreas de cerrado, agricultura e pecuária em três estados brasileiros (Tocantins, Minas Gerais e Mato Grosso). Os resultados indicam uma concentração da distribuição granulométrica nas faixas da areia fina e da média, porém com diferenças entre os solos avaliados. Todos os solos avaliados têm também outras características em comum, como o elevado índice de...

Abstract: Management of remnants in Atlantic Forest is an alternative for their conservation, however, information on the growth and ecology of those species is lacking. This study aimed to describe diametric growth of Balfourodendron riedelianum, Cordia trichotoma and Ocotea diospyrifolia based on its growth rings and to verify the relationship between this growth with the environmental characteristics in different altitude levels and forest types. Diametric growth was higher for the largest tree diameters of the three species. Based on the fitted growth model, the age in which mean annual increment in diameter becomes greater than the current annual increment was 55 years for B. riedelianum (DBH = 18.27 cm), 45 years for C. trichotoma (DBH = 26.56 cm)...

Die landwirtschaftliche Baukultur nachhaltiger gestalten und die kommunikative Wirkung der Bausubstanz erkennen
Provedor de dados: 21
Autores: Dauermann, Angelika; Enneking, Ulrich.
Gebäude sind nicht nur als Funktionseinheiten zu betrachten, sondern auch als Kommunikationsmedium. Die bauliche Gestaltung eines jeweiligen Gebäudes lässt viele Rückschlüsse bezüglich der Einstellungen und Werthaltungen der Bauherrin oder des Bauherrn zu. Und so geben auch Schweineställe und Feldscheunen Informationen über das Wertegefüge des jeweiligen landwirtschaftlichen Unternehmens preis. Die finanziellen Spielräume der Agrarbetriebe sind oftmals nicht groß bei baulichen Investitionen. Unreflektiert sollte die agrarische Baukultur deswegen allerdings nicht bleiben. Die folgenden Ausführungen zeigen auf, dass ein landwirtschaftlicher Betrieb durch eine reflektierte Baukultur einen Zugewinn an Authentizität in der öffentlichen Wahrnehmung erfahren kann.

Die ‘Landwirtschaftliche Individualität’ ist der grundlegende Begriff der biologisch-dynamischen Landwirtschaft. Er ist allerdings mit der wissenschaftlichen Diskussion wenig verbunden. Unser Ziel ist es, einige Aspekte davon und seine aktuelle Bedeutung zu erklären. Die 'landwirtschaftliche Individualität’ beschreibt die Gesamtheit von allen Tieren und Pflanzen samt dem Biotop in einem Betrieb. Dabei wird diese Gesamtheit als ein Organismus höherer Art betrachtet. Als Rudolf Steiner diesen Begriff 1924 einführt, werden zur gleichen Zeit ähnliche Ansichten in der Naturwissenschaft entwickelt, insbesondere in der Ökologie mit dem Begriff des Holozöns. Diese ganzheitlichen Ansichten geraten später allerdings in Vergessenheit. Heutzutage gibt der aktuelle...

Bisher ist wenig darüber bekannt, wie diese gesetzliche Vorgabe die ökologische Agrar- und Ernährungswirtschaft in der Metropolregion unterstützt. Davon ausgehend untersucht die vorliegende Studie regionale Wertschöpfungsketten am Beispiel von Bio-Gemüse und -Kartoffeln und nutzt dafür einen strukturtheoretischen Ansatz. Strukturelle Faktoren beeinflussen die Verwendung von regionalen Bio-Lebensmitteln in der Schulverpflegung. Es besteht eine regionale Lücke. Ohne Intervention reproduzieren die Akteure durch ihr Handeln die...

Diet and ecomorphology of predator fish species of the Amazonian floodplain lakes
Provedor de dados: 49
Autores: Cardoso,Diogo Campos; deHart,Pieter; Freitas,Carlos Edwar de Carvalho; Siqueira-Souza,Flávia Kelly.
Abstract: Amazonian floodplain lakes host a high diversity of predatory fish which coexist and exploit the high diversity of available prey. Morphology could be the characteristic most closely associated with their preferred feeding sources (prey). However, it is unclear whether this association is direct or indirect. If it is indirect, swimming performance or preferential position in the water column could be the most evident characteristic. To examine the degree to which fish morphology of predator fish species is correlated to their dietary inputs, we compared the existence of morphological and feeding dissimilarity among eight predator species with the association between predator morphologies and preferred prey. We collected, measured, and sampled the...

Autores: Silva,Zoraia; Nascimento,Patrícia Elaine Cunha do; Vitule,Jean Ricardo Simões; Frehse,Fabrício de Andrade; Ferraz,Mayara Silva Oliveira; Mourgués-Schurter,Lea Rosa.
Abstract: Fish can vary their diet and feeding dynamics according to biotic and abiotic factors. There is insufficient knowledge regarding these factors in reservoirs, which limits the management of these areas. The aim of this study was to determine the diet of two related and most collected fish species, verify the influence of biotic and abiotic factors on their diet, and also verify the existence of resource sharing by them in an upstream Brazilian reservoir. Fish abundance in the reservoir was calculated and data were provided by 176 specimens of Iheringichthys labrosus (Lütken, 1874) and 255 specimens of Pimelodus maculatus Lacépède, 1803 collected in Camargos reservoir, MG, Brazil. Stomach contents were analysed through the frequency of occurrence...

Autores: Moser,Camila F.; Oliveira,Mateus de; Avila,Fernanda R. de; Dutra-Araújo,Diogo; Farina,Renata K.; Tozetti,Alexandro M.
Abstract: The species Boana bischoffi and Boana marginata are endemic to the Atlantic Forest, where they often occur in sympatry. There is a large gap in the knowledge of natural history of both species. In this study, we aimed to describe and compare the diet composition of B. bischoffi and B. marginata in the southern domain of the Brazilian Atlantic Forest. We analyzed the gastrointestinal contents of 43 individuals of B. bischoffi and 30 individuals of B. marginata. Both showed a high trophic niche overlap (0.90 Ojk). The most important prey categories for both species belonged to the orders Araneae and Coleoptera. The species niche breadth (Bsta) varied from 0.35 to 0.42, suggesting a generalist feeding behavior for both species. Our data provide...

Autores: Mageski,Marcio Marques; Campinhos,Elaine Costa; Duca,Charles; Stein,Maria Carolina; Oliveira,Melissa Peron de; Clemente-Carvalho,Rute Beatriz Garcia.
Abstract Knowledge about the diet of anurans in different environments is essential to understanding important aspects of their trophic ecology. The bromeliad-frog Phyllodytes luteolus inhabits tank bromeliads in sandy coastal plains and lowland forests on the mainland, as well as a continental island in southeastern Brazil. In this work, we describe and analyze the diet of P. luteolus in three environments. We obtained the consumed prey items of 92 frogs (32 from sandy coastal plain, 32 from lowland forest and 28 from the island) via a stomach-flushing procedure. We found some variations in consumed prey composition and prey volume across populations, but ants represented the most important consumed prey in all environments. Only ants had a relative...

Diet, sexual dimorphism and reproduction of sympatric racers Philodryas aestiva and Philodryas patagoniensis from the coastal Brazilian Pampa
Provedor de dados: 42
Autores: QUINTELA,FERNANDO M.; LOEBMANN,DANIEL.
Abstract: Herein we investigated diet, sexual dimorphism and reproductive biology of two sympatric congeneric species at the coastal Brazilian Pampa, Philodryas aestiva and P. patagoniensis. Analysis of the stomach content of the scansorial Philodryas aestiva revealed that it feeds mainly on Anura and small mammals, while it occasionally consumes Insecta, Squamata and Aves. The more terrestrial Philodryas patagoniensis presented a broader diet, composed mainly of Anura, Squamata and small mammals. Insecta and Actinopterygii were found in lower frequencies. In females of both species, snout-vent length was significantly larger than in males, while tail length/snout-vent length ratio was significantly higher in males. Males reach sexual maturity at smaller...

Differences in larval emergence chronotypes for sympatric Rhagoletis brncici Frías and Rhagoletis conversa (Bréthes) (Diptera, Tephritidae)
Provedor de dados: 92
Autores: Frías-Lasserre,Daniel; S,Andrea Luna; Villagra,Cristian A.
ABSTRACT In central Chile, Rhagoletis brncici and R. conversa, can be found in sympatry, associated with the fruit of their native host plants: Solanum tomatillo and S. nigrum (Solanaceae), respectively. Third-stage larvae must emerge from its host in search of pupation sites, and during this period larvae must find an appropriate pupation microhabitat while avoiding predation and adverse abiotic factors. In this study, we explored whether these sympatric species differ in terms of the timing of their larval exit from the host fruit in search of pupation sites. Field-collected fruits from host plants were checked daily for larval emergence, within 24 h, under laboratory conditions, in order to determine the time of the event. We found that these species...

Abstract: The objective of this work was to characterize the spatial variability of soil electrical resistivity due to different soil moisture contents, in an integrated agricultural system. Soil electrical resistivity (ER) was measured with the Automatic Resistivity Profiling (ARP) contact sensor in two dates, in 2016, in a 9.7-ha area with different soil moisture contents. The obtained maps indicated that ER allowed delimiting the regions within the study area and pointing out differences in the movement and accumulation of water in the soil horizons. Although there is a trend of reduction in ER values with increasing soil moisture, the spatial correlation structure of ER is similar.

The trophic fate of various food sources is of central interest for ecologists, yet not well understood in coastal lagoon food webs. In this field study, fatty acids (FA), stable isotopes (SI), and compound-specific isotopic analysis (CSIA) on FA were used to investigate how diets from oceanic and local sources are retained in a bivalve species (Spondylus crassisquama; Lamarck 1819) along a transect in the Ojo de Liebre lagoon (BCS, Mexico). Results from SI and FA indicated the contribution of oceanic diatoms at the entrance of the lagoon, through 15N enrichment, and higher proportions of 16:1n-7 and 20:5n-3 in digestive glands. In the inner bay, higher abundance of 18-carbon FA (18:1n-9, 18:3n-3, 18:4n-3) suggested a higher contribution of...

To prevent the settlement and/or the growth of fouling organisms (i.e. bacteria, fungi or microalgae), benthic sessile species have developed various defense mechanisms among which the production of chemical molecules. While studies have mostly focused on the release of chemical compounds by single species, there exist limited data on multi-species assemblages. We used an integrative approach to explore the potential interactive effects of distinct assemblages of two corals species and one giant clam species on biofouling appearance and composition. Remarkably, we found distinct biofouling communities suggesting the importance of benthic sessile assemblages in biofouling control. Moreover, the assemblage of 3 species led to an inhibition of biofouling,...

Provedor de dados: 56
Autores: Yang,Hui-li; Zhang,Hong-zhi; Meng,Fan-rong; Han,Shu-yi; Zhang,Miao.
Preeclampsia is a major reason of morbidity and mortality in pregnant women and perinatal fetus. Hence, it is of prime importance that diagnostic markers are defined to predict chances of preeclampsia in pregnant women. It has been previously shown that microRNA (miRNA)-376c expression is decreased in the placenta of preeclampsia patients at term. Even though this decrease was not mimicked in the placenta at the pre-term stage, miR-376c expression was decreased in the plasma of these patients as early as the second trimester. Plasma and placenta specimens were obtained from pregnant women having unifetal gestation undergoing perinatal care between January 2014 and December 2016 (n=49). Early trimester placentas were collected from patients undergoing...

ABSTRACT Water deficit is responsible for a negative impact on agricultural systems. Several physiological, biochemical, and molecular processes are initiated as a response to water-deficit stress. Quantifying the differential expression of the genes involved in the response to water-deficit stress plays a key role in the development of molecular strategies for engineering water-stress tolerance in plants. Therefore, the present study aims to evaluate the expression of key genes involved in the water-deficit response process in peach trees cv. Chimarrita grafted onto two different rootstocks. The experimental design was completely randomized, with four treatments that correspond to the evaluation periods: day zero (control), the fourth, seventh, and ninth...

ABSTRACT: Resistance evolution in weeds against all major herbicide groups demand investigations to identify various factors responsible for resistance development. Herbicide hormesis has not yet been included in the list of factors promoting the evolution of resistance. Studies were conducted to evaluate the degree of hormesis in fenoxaprop-p-ethyl susceptible and resistant Phalaris minor to provide a first indication of whether hormesis is a potential factor in the development of resistance. In the first experiment, a wide range of doses up to 160% of the recommended field rate was used to identify potential hormetic doses for resistant and susceptible P. minor populations. Doses below 40% have been designated as potential hormetic doses. In the second...

Differential influence of life cycle on growth and toxin production of three   Pseudo-nitzschia   species (Bacillariophyceae)
Provedor de dados: 5
Autores: Sauvey, Aurore; Claquin, Pascal; Le Roy, Bertrand; Le Gac, Mickael; Fauchot, Juliette.
We used a multi‐strain approach to study the intra‐ and interspecific variability of the growth rates of three Pseudo‐nitzschia species – P. australis, P. fraudulenta, and P. pungens – and of their domoic acid (DA) production. We carried out mating and batch experiments to investigate the respective effects of strain age and cell size, and thus the influence of their life cycle on the physiology of these species. The cell size ‐ life cycle relationship was characteristic of each species. The influence of age and cell size on the intraspecific variability of growth rates suggests that these characteristics should be considered cautiously for the strains used in physiological studies on Pseudo‐nitzschia species. The results from all three species do not...

ABSTRACT:  Dioctophyme renale is a parasite of the nematode class that can infect various species, including humans and dogs. Usually, the parasite migrates to the right kidney of the definitive host. Although, aberrant migrations have been previously reported, they mainly occur without clinical manifestations. No reports of dyspnea secondary to D. renale infestation has been found in the reported literature. The aim of this paper is to report intense respiratory distress caused by the presence of the parasite in the thoracic cavity of a dog. Radiographic images revealed multiple circular structures with a cavity with a radiopaque, thick contour in the thorax, which raised the suspicion of pulmonary bullae. Ultrasound examination revealed nematode...

Abstract: Diosmin is a flavone glycoside clinically used as the main component of Daflon for the treatment of venous diseases. Several studies demonstrated that this natural compound can induce apoptosis in different tumors. However, isolated diosmin has not been studied regarding its effects on glioblastoma so far. Since glioblastoma is a highly lethal and fast-growing brain tumor, new therapeutic strategies are urgently needed. Herein, we evaluated the role of this flavonoid against glioblastoma cells using in vitro assays. Diosmin significantly reduced the viability of GBM95, GBM02, and U87MG glioblastoma cells, but not of healthy human astrocytes, as verified by MTT assay. Vimentin immunostaining showed that diosmin induced morphological changes in...

Autores: MOLINERI,CARLOS; NIETO,CAROLINA; DOMÍNGUEZ,EDUARDO.
Abstract: The distribution of aquatic insects has been poorly explored in quantitative analyses aiming at the historical reconstruction of area relationships in the Neotropics. Ephemeroptera is an ancient group, characterized by its low vagility, and of high richness and endemicity in this region. Systematic knowledge of the group has enormously increased in the last decades, achieving a sufficient background to explore biogeographical historical patterns. Our aim is to reconstruct area history in the Neotropics using the rationale of Barrier biogeography (Hovenkamp protocol). We present eleven mayfly phylogenies, representing groups that evolved independently at least from the Jurassic (i.e., not a one-taxon history). With these groups, we conducted...

Urban gardens are popular green spaces that have the potential to provide essential ecosystem services, support human well-being, and at the same time foster biodiversity in cities. We investigated the impact of gardening activities on five soil functions and the relationship between plant (600 spp.) and soil fauna (earthworms: 18 spp., springtails: 39 spp.) in 85 urban gardens (170 sites) across the city of Zurich (Switzerland). Our results suggest that high plant diversity in gardens had a positive effect on soil fauna and soil multifunctionality, and that garden management intensity decreased plant diversity. Indices of biological activity in soil, such as organic and microbial carbon and bacterial abundance, showed a direct positive effect on soil...

Autores: Caruana, Amandine; Ayache, Nour; Raimbault, Virginie; Rétho, Michael; Hervé, Fabienne; Bilien, Gwenael; Amzil, Zouher; Chomérat, Nicolas.
We confirm an amnesic shellfish poisoning risk associated with domoic acid production by the species Pseudo-nitzschia plurisecta and determine the toxin profile, which includes three domoic acid isomers. Although the species was reported once in European waters, along the Spanish Atlantic coast, here we describe and characterize P. plurisecta collected during the first occurrence in French Atlantic waters. Three strains (IFR-PPL-15.1, 15.2 and 15.3) were isolated from French coastal water samples in June 2015. These strains were identified and characterized by microscopic observation, molecular (ITS region sequencing and phylogenetic analysis) and metabolite (toxins and pigments) analyses. The cell shape is lanceolate and the valve contains a central...

ABSTRACT The aim of this study was to evaluate the effect of concentrations of caffeine on the viability, synthesis activity and gene expression in cultures of chondrocytes. Extracted articular cartilage from the femurs and tibias of 15 Wistar rats at three days old to isolate chondrocytes. Chondrocytes were cultured in chondrogenic medium (control) or supplemented with caffeine (0.5, 1.0, 2.0mM). Cell viability, alkaline phosphatase activity and collagen synthesis were assessed using colorimetric assays at 7, 14, 21 days. The chondrocyte cultures of all groups grown under coverslips were stained with hematoxylin-eosin to determine the percentage of cells/field and with PAS, safranin O, alcian blue to determine the percentage of matrix chondrogenic/field...

ABSTRACT Bloodstream infections (BSIs) are serious infections associated with high rates of morbidity and mortality. Every hour delay in initiation of an effective antibiotic increases mortality due to sepsis by 7%. Turnaround time (TAT) for conventional blood cultures takes 48 h, forcing physicians to streamline therapy by exposing patients to broad-spectrum antimicrobials. Our objective was (1) to evaluate the accuracy and TAT of an optimized workflow combining direct matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) and in-house real-time polymerase chain reaction (PCR) for bacterial identification and antimicrobial resistance profiling directly from positive blood bottles for diagnosing bloodstream infections...

Rivers (on land) and turbidity currents (in the ocean) are the most important sediment transport processes on Earth. Yet, how rivers generate turbidity currents as they enter the coastal ocean remains poorly understood. The current paradigm, based on laboratory experiments, is that turbidity currents are triggered when river plumes exceed a threshold sediment concentration of ~1 kg.m‐3. Here we present direct observations of an exceptionally dilute river‐plume, with sediment concentrations one order of magnitude below this threshold (0.07 kg.m‐3), which generated a fast (1.5 m.s‐1), erosive, short‐lived (6 min) turbidity current. However, no turbidity current occurred during subsequent river‐plumes. We infer that turbidity currents are generated when...

ABSTRACT Selection of more productive carrot genotypes is fundamental for crop breeding programs aiming to increase productivity and reduce cost production. Thus, the aim of this work was to evaluate gains from direct selection and to measure its effects on other agronomic traits of interest in carrots. Thirty six carrot genotypes were evaluated in two experiments: the first, sown in the second half of November 2016 and the second one in the first week of March 2017. The experimental plots covered a useful area of 1.5 m2, in transversal rows and 0.10-m double spacing between single rows x 0.20-m between double rows in a randomized block design with 3 replicates. At 90 days, the incidence of leaf blight was evaluated using a note scale and 100 days after...

Otolith shape analysis is an efficient fish stock identification tool. However, most applications used left and right otoliths or only one of them arbitrarily chosen without testing for biases resulting from potential directional bilateral asymmetry (DA) in otolith shape, i.e. a unimodal population-level deviation form bilateral symmetry between right and left otolith shapes. In this study, 560 bogues (Boops boops) were sampled from 11 geographical locations from the Canary Islands to the Aegean Sea and elliptical Fourier descriptors were used to describe their otoliths’ shape. First, a significant otolith DA was observed at the global scale with an average amplitude of 2.77%. However, at the scale of sampling locations, DA was not always significant and...

Discovering the physical onerous activities in manual sesame grain harvest using postural analysis
Provedor de dados: 111
Autores: Hayati, Abdullah; Marzban, Afshin; Leylizadeh, Masoud.
The sesame oil is accounted as high-priced and high-quality oil, but its production is less than that of major oilseeds due to labor-intensive harvest similar to many agricultural activities. These types of activities are often onerous leading the workers to occupational risk factors such as musculoskeletal disorders. Thus, the aim of this study was to evaluate the manual sesame grain harvest (consisting of work tasks of mowing, tying and shaking) regarding postural workloads to identify onerous activities during this operation which would help to mitigate some problems of the sesame grain production chain. Ovako Working posture Analysis System (OWAS) was used for working posture analysis of twenty-six male workers employed for this study. Results showed...

Abstract: Eugenia uniflora L. (Myrtaceae) is a tree species widely distributed in South America suffering the effects of the exploitation of natural populations. In this study, we employed low coverage sequencing of the E. uniflora genome for mining of SSR markers. The de novo assembly generated 2,601 contigs with an average length of 1139 bp and spans 3.15 Mb. A total of 76 dimer, 33 trimer and two compound SSR loci were identified. Twelve selected SSR loci were employed to genotype 30 individuals from two natural populations. A total of 73 alleles were detected (mean A= 6.1) were observed, the mean effective number of alleles was Ae = 3.91, mean Ho was 0.23 and mean HE was 0.70). The mean Wright’s within population fixation index was FIS = 0.66 and...

Investigation of phytoplankton from East China Sea of the Pacific Ocean, offshore Réunion Island of the Indian Ocean, and the French Atlantic coast revealed a species of poorly known armored fusiform dinoflagellate. To clarify this species, morphology and phylogeny based on mitochondrial and nuclear protein gene sequence (Cox1, Cob and Hsp90) concatenated with the SSU, ITS region and LSU rDNA sequences were analysed. Epifluorescence and scanning electron microscopy observations revealed that the nucleus of the specimen was elongated, sausage-shaped and located equatorially on the left lateral side of the cell, and that the plate formula is Po, 3′, 1a, 6″, 6C, 8S, 5‴, 1p, 2′‴.

Tropical soils are a major contributor to the balance of greenhouse gas (GHG) fluxes in the atmosphere. Models of tropical GHG fluxes predict that both the frequency of drought events and changes in atmospheric deposition of nitrogen (N) will significantly affect dynamics of soil carbon dioxide (CO2) and methane (CH4) production and consumption. In this study, we examined the combined effect of a reduction in precipitation and an increase in nutrient availability on soil CO2 and CH4 fluxes in a primary French Guiana tropical forest. Drought conditions were simulated by intercepting precipitation falling through the forest canopy with tarpaulin roofs. Nutrient availability was manipulated through application of granular N and/or phosphorus (P) fertilizer to...

Disentangling ecosystem engineering from short-term biotic effects of a strong invader on a native foundation species
Provedor de dados: 5
Autores: Proença, Barbara; Romuald, Marine; Auby, Isabelle; Ganthy, Florian; Sottolichio, Aldo; Michalet, Richard.
Ecosystem engineering effects of dominant species on habitats and consequently on other species are likely to propagate through time at longer distance than the close neighbourhood. Such effects are important to disentangle from short-term biotic effects, especially in biological invasions, as engineering can explain changes in invasion rates over the course of the invasion. We assessed the contribution and spatial dynamics of ecosystem engineering effects of a strong invader, the cordgrass Spartina anglica, on Zostera noltei, a foundation seagrass species of muddy intertidal systems in Europe. Z. noltei transplants were grown at different positions along transects crossing intact S. anglica patches, cut patches and nearby bare sediment on tidal flats in...

Disentangling the Mesoscale Ocean-Atmosphere Interactions
Provedor de dados: 5
Autores: Renault, L.; Masson, S.; Oerder, V.; Jullien, Swen; Colas, François.
In the past decades, the use of scatterometer data allowed to demonstrate the global ubiquity of the Ocean Mesoscale Thermal FeedBack (TFB) and Current FeedBack (CFB) effects on surface winds and stress. Understanding these air‐sea interactions is of uttermost importance as the induced atmospheric anomalies partly control the ocean circulation, and, thus, can influence the Earth Climate. Whether the TFB and CFB effects can be disentangled, and whether satellite scatterometers can properly reveal them, remain rather unclear. Here, using satellite observations and ocean‐atmosphere coupled mesoscale simulations over 45° S‐45° N, we show that the CFB effect can be properly characterized and unraveled from that due to the TFB. We demonstrate that the TFB can be...

Disentangling the relative impacts of climate change and human activities on fluvial sediment supply to the coast by the world’s large rivers: Pearl River Basin, China
Provedor de dados: 5
Autores: Ranasinghe, Roshanka; Wu, Chuang Shou; Conallin, John; Duong, Trang Minh; Anthony, Edward Jamal.
The world’s large rivers are under stress and experiencing unprecedented changes in hydrology, ecosystems, and fluvial sediment loads. Many of these rivers terminate at the great deltas of the world (home to 500 million people), which depend on fluvial sediments for their very existence. While fluvial sediment loads of large rivers have already been greatly modified by human activities, climate change is expected to further exacerbate the situation. But how does the effect of climate change on fluvial sediment loads compare with that of human impacts? Here, we address this question by combining historical observations and 21st century projections for one of the world’s largest 25 rivers containing two mega dams; Pearl River, China. Our analysis shows that...

Ocean ecosystems are in decline, yet we also have more ocean data, and more data portals, than ever before. To make effective decisions regarding ocean management, especially in the face of global environmental change, we need to make the best use possible of these data. Yet many data are not shared, are hard to find, and cannot be effectively accessed. We identify three classes of challenges to data sharing and use: uploading, aggregating, and navigating. While tremendous advances have occurred to improve ocean data operability and transparency, the effect has been largely incremental. We propose a suite of both technical and cultural solutions to overcome these challenges including the use of natural language processing, automatic data translation,...

Disruptive coloration and habitat use by seahorses
Provedor de dados: 83
Autores: Duarte,Michele; Gawryszewski,Felipe M.; Ramineli,Suzana; Bessa,Eduardo.
ABSTRACT Predation avoidance is a primary factor influencing survival. Therefore, any trait that affects the risk of predation, such as camouflage, is expected to be under selection pressure. Background matching (homochromy) limits habitat use, especially if the habitat is heterogeneous. Another camouflage mechanism is disruptive coloration, which reduces the probability of detection by masking the prey’s body contours. Here we evaluated if disruptive coloration in the longsnout seahorse, Hippocampus reidi, allows habitat use diversification. We analyzed 82 photographs of animals, comparing animal and background color, and registering anchorage substrate (holdfast). We tested whether the presence (disruptive coloration) or absence of bands (plain...

Dissolved organic nitrogen production and export by meridional overturning in the eastern subpolar North Atlantic
Provedor de dados: 5
Autores: Fernández-castro, Bieito; Álvarez, Marta; Nieto-cid, Mar; Zunino, Patricia; Mercier, Herle; Álvarez-salgado, Xosé Antón.
Dissolved organic matter (DOM) is produced in the surface and exported towards the deep ocean, adding ∼2 PgC yr−1 to the global carbon export. Due to its central role in the Meridional Overturning Circulation (MOC), the eastern subpolar North Atlantic (eSPNA) contributes largely to this export. Here we quantify the transport and budget of dissolved organic nitrogen (DON) in the eSPNA, in a box delimited by the OVIDE 2002 section and the Greenland‐Iceland‐Scotland sills. The MOC exports &gt;15.9 TgN yr−1 of DON downwards and, contrary to the extended view that these are materials of subtropical origin, up to 33% of the vertical flux derives from a net local DON production of 7.1 ± 2.6 TgN yr−1. The low C:N molar ratio of DOM production (7.4 ± 4.1) and the...

Provedor de dados: 42
Autores: PRINCIPE,ROMINA E.; MÁRQUEZ,JAVIER A.; CIBILS-MARTINA,LUCIANA.
Abstract: The assessment of biotic-habitat relationships provides key information to predict biotic responses to perturbations and important tools for river management and monitoring. This study aimed to assess the spatial distribution of Ephemeroptera and Trichoptera in mountain streams of central Argentina. We evaluated the effect of seasonality and identified the variables conditioning the abundance of the assemblages and the habitat with the highest taxonomic richness. Sampling was carried out in four streams (Carcarañá River basin) during high and low water periods. Three lotic habitats were sampled: riffles, coarse substrate runs, and fine substrate runs; and physicochemical and habitat variables were measured. We found differences in assemblage...

The present work examines the spatio-temporal biomass trends of Mullus barbatus and Mullus surmuletus in the Mediterranean Sea through the analysis of a time series of data coming from the Mediterranean International Trawl Surveys (MEDITS), accomplished annually from 1994 to 2015. The biomass of both species showed clear declining trends below 150 to 200 m depth, which were steeper in the case of M. barbatus. Increases in temporal biomass trends were observed for M. barbatus from 2008 onward in most geographic sub-areas (GSAs), while stability was mostly observed for M. surmuletus. For both species, dynamic factor analysis revealed similarities among neighbouring GSAs and the subsequent cluster analysis identified two major GSA groups corresponding to the...

Abstract The White-collared Kite (Leptodon forbesi) is an endemic and threatened raptor of the Brazilian Atlantic Forest. Here we present the known records of the species, describe the vegetation types where it was found and show Ecological Niche Models generated using Maxent algorithm. Most of the presence data were recorded in open ombrophilous forest and seasonal semideciduous forest in the states of Alagoas and Pernambuco. Maxent model had a good performance (AUC = 0.982 ± 0.004 SD), showing higher suitability for the species from Paraíba to Alagoas states. Maxent average model revealed a distribution range of 20,344 km² and an area of occupancy of 1,636.89 km². The most suitable areas for the species are those near watercourses and streams. We suggest...

ABSTRACT The Aptian-Albian paleoichthyofauna in Brazil and Africa is quite diverse, yet their geographic patterns still require accounts. This work consists of a panbiogeographical analysis of paleoichthyofauna from Aptian-Albian through track analysis. Geographic coordinates were obtained and converted into paleocoordinates. Individual Tracks (ITs) and Generalized Tracks (GTs) were built with the aid of ArcView GIS v3.2 program using Trazos2004 extension. As a result, four GTs and tree Biogeographic Nodes (A, B and C) had been identified. GTs 1 and 2 shows two different faunas. GT3 indicates similarity between Brazil and Africa paleoichthyofauna suggesting the break-up of Gondwana as the event that separated it. GT4 represents a probable local seaway...

Divergent Capacity of Scleractinian and Soft Corals to Assimilate and Transfer Diazotrophically Derived Nitrogen to the Reef Environment
Provedor de dados: 5
Autores: Pupier, Chloe A.; Bednarz, Vanessa N.; Grover, Renaud; Fine, Maoz; Maguer, Jean-francois; Ferrier-pages, Christine.
Corals are associated with dinitrogen (N-2)-fixing bacteria that potentially represent an additional nitrogen (N) source for the coral holobiont in oligotrophic reef environments. Nevertheless, the few studies investigating the assimilation of diazotrophically derived nitrogen (DDN) by tropical corals are limited to a single scleractinian species (i.e., Stylophora pistillata). The present study quantified DDN assimilation rates in four scleractinian and three soft coral species from the shallow waters of the oligotrophic Northern Red Sea using the N-15(2) tracer technique. All scleractinian species significantly stimulated N, fixation in the coral-surrounding seawater (and mucus) and assimilated DDN into their tissue. Interestingly, N-2 fixation was not...

1 – Introduction   Responding to the many sustainability issues related to modern industrial agriculture (air, soil and water pollution, biodiversity loss, etc.), the diversity argument was brought forward by scientists (Kremen et al., 2012). Diversified farming systems intentionally include functional agrobiodiversity, i.e. crops, seeded and permanent pastures, rangelands and animal genotypes and species chosen by the farmer to manage his farm. These systems presumably provide ecosystem services while reducing the input needed for production. Agrobiodiversity is also assumed to strengthen the robustness and resilience of livestock farming systems.   Because of their inherent complexity, research on diversified farming systems is limited. Literature on the...

Provedor de dados: 21
Autores: Feher, Judit; Padel, Susanne; Rossi, Adanella; Drexler, Dora; Oehen, Bernadette.
Current food systems and associated agricultural practices have led to a loss of crop diversity. The  widespread adoption of genetically uniform crop varieties  may also increase the vulnerability of production systems  and reduce their adaptability to new environmental challenges. DIVERSIFOOD has explored different approaches  aimed at increasing crop genetic diversity, and as a result, make biodiverse food available to consumers. These approaches have the potential to promote sustainable, locally adapted farming systems, provide autonomy to farmers, support local short and fair supply chains and reconnect farmers and consumers. In order to support these approaches, the following policy changes are needed:  1) The legal status of heterogeneous cultivars...

ABSTRACT Coffea canephora (Conilon coffee) has great economic importance for the state of Acre, in northern Brazil. The use of insecticides in this crop has increased considerably in recent years. In order to find species of green lacewing (Chrysopidae, Neuroptera) with potential for use in biological pest control in coffee plantations, we sampled green lacewings during one year in an experimental plantation of Conilon coffee in Acre, in order to assess the diversity, abundance and seasonal occurrence of Chrysopidae species. Samplings were carried out weekly using an entomological net. Overall, 1079 specimens of seven green lacewing species were collected: Ceraeochrysa cincta, Ceraeochrysa claveri, Ceraeochrysa cubana, Ceraeochrysa everes, Chrysoperla...

Diversity and evolution of Amazonian birds: implications for conservation and biogeography
Provedor de dados: 42
Autores: RIBAS,CAMILA C.; ALEIXO,ALEXANDRE.
Abstract: Amazonia has been a focus of interest since the early days of biogeography as an intrinsically complex and extremely diverse region. This region comprises an intricate mosaic that includes diverse types of forest formations, flooded environments and open vegetation. Increased knowledge about the distribution of species in Amazonia has led to the recognition of complex biogeographic patterns. The confrontation of these biogeographic patterns with information on the geological and climatic history of the region has generated several hypotheses dedicated to explain the origin of the biological diversity. Genomic information, coupled with knowledge of Earth’s history, especially the evolution of the Amazonian landscape, presents fascinating...

Pearl farming lagoons are economically important, yet poorly studied ecosystems in French Polynesia. This paper describes a study conducted in 2016 in Takaroa (Tuamotu Archipelago), an atoll recurrently affected by harmful algal bloom (HAB) events. The objectives were to gain insight into phytoplankton community composition, identify the main bloom-forming species and investigate their potential for toxicity. A mesocosm approach was used to assess the response of phytoplankton communities to 3 nutrient treatments: Conway with Si, Si-depleted f/2 and a commercial N-P fertilizer. In total, 87 morpho-species were described from Takaroa lagoon, with dinoflagellates as the most diverse group. Diatoms (Extubocellulus sp., Cylindrotheca closterium, Nitzschia...

Whale falls are important environments contributing to biodiversity, connectivity and evolutionary novelty in deep-sea ecosystem. Notwithstanding, most of this knowledge is based in studies from NE Pacific basin. Interestingly, the only known natural whale fall on the SW Atlantic has faunal composition affinities with carcasses from other deep-ocean basins. In this carcass, annelid worms belonging to Hesionidae are abundant and species-rich, and include some shared species with NE Pacific Ocean. Here we evaluate the diversity of Hesionidae on the SW Atlantic using new information of implanted whale bones and explore whether some species have interbasin distribution or if they represent cryptic species in different basins. We described, using morphological...

Abstract The diversity of rhizobial isolates in tropical dry forests (TDF) has been studied due to the great importance of finding new species of bacteria capable of fixing nitrogen in tree legumes. In the Brazilian TDF (caatinga), Leguminosae is the most important family of plants, so the knowledge of microbial communities that make symbioses with native plants can help in the understanding of the interaction plant-microorganisms, as well as in the optimization of biological processes that can improve the cultivation system in an area so rich and understudied. In this study was determined the characteristics of rhizobia isolated from nodules of Mimosa tenuiflora (Willd.) Poir., Piptadenia stipulacea (Benth.) Ducke and Mimosa caesalpiniifolia Benth, grown...

DNA methylation reprogramming, TE derepression, and postzygotic isolation of nascent animal species
Provedor de dados: 5
Autores: Laporte, M.; Le Luyer, Jeremy; Rougeux, C.; Dion-côté, A.-m.; Krick, M.; Bernatchez, L.
The genomic shock hypothesis stipulates that the stress associated with divergent genome admixture can cause transposable element (TE) derepression, which could act as a postzygotic isolation mechanism. TEs affect gene structure, expression patterns, and chromosome organization and may have deleterious consequences when released. For these reasons, they are silenced by heterochromatin formation, which includes DNA methylation. Here, we show that a significant proportion of TEs are differentially methylated between the “dwarf” (limnetic) and the “normal” (benthic) whitefish, two nascent species that diverged some 15,000 generations ago within the Coregonus clupeaformis species complex. Moreover, TEs are overrepresented among loci that were demethylated in...

Autores: Barbosa,Marisângela Viana; Pedroso,Daniela de Fátima; Curi,Nilton; Carneiro,Marco Aurélio Carbone.
ABSTRACT Soil structure, which is defined by the arrangement of the particles and the porous space forming aggregates, is one of the most important properties of the soil. Among the biological factors that influence the formation and stabilization of soil aggregates, arbuscular mycorrhizal fungi (AMF) are distinguished due to extrarradicular hyphae and glomalin production. In this context, the objective of this study was to evaluate different AMF (Acaulospora colombiana, Acaulospora longula, Acaulospora morrowiae, Paraglomus occultum and Gigaspora margarita) associated with Urochloa brizantha (A. Rich.) Stapf on soil aggregate stability. The study was conducted in a completely randomized design, using an Oxisol and autoclaved sand 2:1 (v/v), with seven...

Do environmental conditions (temperature and food composition) affect otolith shape during fish early-juvenile phase? An experimental approach applied to European Seabass (Dicentrarchus labrax)
Provedor de dados: 5

Otolith shape is an efficient tool for fish stock discrimination. Therefore, it is crucial to identify the environmental parameters that could influence otolith morphogenesis and growth. Current global ocean warming negatively affects the production of polyunsaturated fatty acids (EPA and DHA) by phytoplankton and thus their availability in marine food webs. As EPA and DHA are essential nutrients for most fish species, their deficiency could affect many aspects of fish physiology, notably otolith morphogenesis. The goal of this study was to assess experimentally the combined influences of temperature (T) and dietary polyunsaturated fatty acid (PUFA) content on European seabass (Dicentrarchus labrax) otolith morphogenesis during early life stages. 300...

ABSTRACT Euglossa Latreille, 1802 do not live in large colonies, and these are usually maintained or “reactivated” by new females, subordinate to their mother, which construct and provision brood cells. This study aimed to obtain information about the natural history of Euglossa cordata (Linnaeus, 1758) specially focusing on nest behavior. Our specific objective was to answer the following question: do E. cordata females reside in a single nest? We construct 14 artificial nesting boxes and made them available for E. cordata bees in natural environment for seven months. During this time, we use a re-marking method to identify bee fidelity to a single nest box. More specifically, we record bee permanence in the nests, the time bees take to provision brood to...

ABSTRACT This research was conducted to investigate the effect of live and inactive sugarcane yeast on beef cattle voluntary intake, apparent digestibility of nutrients, ruminal pH, volatile fatty acids (VFA) concentrations, and ruminal ammonia. Five rumen-cannulated Nellore heifers were distributed in a 5×5 Latin square design, with five experimental periods of 15 days, with seven days for adaptation to the additives and the remaining days for data records and sampling. Total mixed ration (TMR) was composed by corn silage (20%) and concentrate (80%) based on corn and soybean meal. Five treatments were evaluated: without additive use (negative control; NC); chemical buffer addition – 0.71% in concentrate DM of sodium bicarbonate and 0.18% of magnesium...

Autores: Costa,Leonardo Lopes; Machado,Phillipe Mota; Zalmon,Ilana Rosental.
ABSTRACT The role of morphodynamic features such as grain size, swash climate and wave action on the macrofauna of beaches are well-known. However, few studies have investigated natural disturbances as potential drivers of temporal community variations. In southeastern Brazil, we sampled the intertidal macrofauna of two sandy beaches to test whether seasonal disturbances as the frequency of storm wave events (SWE) and rainfall have significant influence on their composition and abundance. The macrofauna assemblage differed significantly between the rainy and the dry seasons, but rainfall was not the main driver of community changes, although both beaches are in the vicinity of extensive river plumes. Actually, SWE explained most macrofauna richness...

Do polyembryonic seeds of Carapa surinamensis (Meliaceae) have advantages for seedling development?
Provedor de dados: 36
Autores: FERREIRA,Débora Najara de SOUZA; CAMARGO,José Luís Campana; FERRAZ,Isolde Dorothea Kossmann.
ABSTRACT Polyembryony is the differentiation and development of multiple embryos in a single seed. This characteristic can provide advantages, as more than one embryo is produced with the same amount of resources, and the probability of establishment of at least one seedling increases. However, sibling seedlings may also increase competition, affecting development and survival. In the present study, the possible advantages and disadvantages of polyembryony were analyzed in the initial establishment of seedlings of Carapa surinamensis (Meliaceae), a tree species that produces monoembryonic or polyembryonic seeds. In this regard, the development of single seedlings was compared with a pair of seedlings emerging from polyembryonic seeds. We compared the...

The potential presence of nanoplastics (NP) in aquatic environments represents a growing concern regarding their possible effects on aquatic organisms. The objective of this study was to assess the impact of polystyrene (PS) amino-modified particles (50  nm PSNH2) on the cellular and metabolic responses of the diatom Chaetoceros neogracile cultures at two essential phases of the growth cycle, i.e. exponential (division) and stationary (storage) phases. Both cultures were exposed for 4 days to low (0.05 μg mL−1) and high (5 μg mL−1) concentrations of PS-NH2. Exposure to NP impaired more drastically the major cellular and physiological parameters during exponential phase than during the stationary phase. Only an increase in ROS production was observed at...

Autores: Ferreira,G.A.; Felippe,L.C.; Bertuzzi,R.; Bishop,D.J.; Ramos,I.S.; De-Oliveira,F.R.; Lima-Silva,A.E.
We investigated the effect of caffeine ingestion combined with a 2-wk sprint interval training (SIT) on training-induced reductions in body adiposity. Twenty physically-active men ingested either 5 mg/kg of cellulose as a placebo (PLA, n=10) or 5 mg/kg of caffeine (CAF, n=10) 60 min before each SIT session (13×30 s sprint/15 s of rest). Body mass and skinfold thickness were measured pre- and post-training. Energy expenditure was measured at rest, during exercise, and 45 min after exercise in the first SIT session. Body fat was similar between PLA and CAF groups at pre-training (P&gt;0.05). However, there was a significant decrease in body fat after training in the CAF group (−5.9±4.2%, P&lt;0.05) but not in PLA (1.5±8.0%, P&gt;0.05). There was no...

Does Ferralsol Clay Mineralogy Maintain Potassium Long-Term Supply to Plants?
Provedor de dados: 90
Autores: Moterle,Diovane Freire; Bortoluzzi,Edson Campanhola; Kaminski,João; Rheinheimer,Danilo dos Santos; Caner,Laurent.
ABSTRACT Ferralsols ( Latossolos ) should contain few or no 2:1 clay minerals and have low potassium (K) contents, and consequently low levels of non-exchangeable K forms are expected. The aim of this study was to evaluate how the clay mineralogy of a Ferralsol affects the soil K dynamics in response to K fertilization during cropping and whether the clay mineralogy was altered due to successive crops and K fertilization. A tropical Brazilian Ferralsol under field conditions was sampled (0.00-0.20 m) in contrasting K fertilization plots: no K application (control plot) and 3,200 kg ha-1 applied K2O fertilizer. These two treatments were submitted at eight different crop cycles, performed in pots under greenhouse conditions, and fertilized with 0, 30, and 90...

Autores: Tatemoto,Patricia; Bernardino,Thiago; Rodrigues,Frederico Augusto Mazzocca Lopes; Zanella,Adroaldo José.
ABSTRACT The objective of this study was to evaluate the effects of stereotypic behavior on productivity measures in sows. Frequent expression of stereotypies by pigs has been reported, even when pigs are not maintained in crates. This behavior is only observed in animals kept in captivity and is a wide-range welfare indicator, since it is considered to develop in situations of chronic stress or frustration. When comparing groups of sows showing low or high frequency of stereotypy expression, we found that stereotypic behavior did not affect productivity. Moreover, it did not affect physiological welfare indicators, such as salivary cortisol concentration or glucocorticoids in the placenta. There were no differences in productivity parameters, including...

Abstract Colorectal cancer has become a serious problem, especially in highly developed countries. As reported by the World Health Organization, the number of colon cancer cases in the world in 2012 amounted to 1.36 million. It is the second most common cancer in females (614,000 cases, 9.2% of the total) and the third in males (746,000 cases, 10.0% of the total) worldwide. It is believed that TGFβ pathway elements are involved in the pathogenesis of colorectal cancer. This study assessed one of these elements, the ACVR2A gene. Qualitative and quantitative analyses of the ACVR2A gene in 84 patients with colorectal cancer was performed. There was no statistically significant association between ACVR2A gene expression and age, gender, histological type,...

ABSTRACT: The hairy fleabane ( Conyza bonariensis (L.) Cronq.) is among the most problematic glyphosate-resistant weeds to manage around the world. In weed science, molecular approaches such as RNA sequencing (RNA-Seq) and quantitative reverse-transcription polymerase chain reaction (RT-qPCR) have been employed to study molecular responses to glyphosate treatment in  Conyza species. Glyphosate treatment leads to reactive oxygen species (ROS) production in plants which could damage the RNA. Degraded RNA is an issue and can compromise further molecular analysis. Thus, the objective of this study was to evaluate whether glyphosate treatment interferes negatively on RNA integrity of glyphosate-resistant and -sensitive hairy fleabane biotypes.

Does the widely distributed rodent Calomys tener (Cricetidae: Sigmodontinae) constitute a single evolutionary unit?
Provedor de dados: 103
Autores: González-Ittig,Raul E.; Kandel,Narayan P.; Bonvicino,Cibele R.; Salazar-Bravo,Jorge.
ABSTRACT The nominal species Calomys tener (Winge, 1887) ranges broadly in open lands of the Caatinga, Cerrado, Pantanal and Mata Atlântica of Brazil, and was recently reported from the Pampas of southern Brazil, and in the Selva Paranaense of eastern Paraguay and northeastern Argentina. This rodent can be infected with the pathogenic Araraquara hantavirus in Brazil. Given that most epidemiological studies have not taken into account updated taxonomic findings of their rodent hosts, in this study, we obtained sequence data of the Cyt-b and COI genes of specimens of C. tener from 22 different geographical localities from throughout the currently known distribution of the species (including individuals from Argentina, Paraguay, Bolivia, and Brazil) to test...

The objective of this study was to investigate the effect of whole body vibration (WBV) exercise on oxidative stress markers in a group of women with fibromyalgia (FM) compared to a group of healthy women (CT). Twenty-one women diagnosed with FM and 21 age- and weight-matched healthy women were enrolled the study. Plasma oxidative stress markers (primary outcomes) were evaluated at rest and after WBV, and included thiobarbituric acid reactive substances (TBARS), iron reduction capacity (FRAP), superoxide dismutase antioxidant enzymes activity (SOD), and catalase (CAT). At rest, the FM group had higher TBARS (P&lt;0.001) and FRAP (P&lt;0.001), and lower CAT (P=0.005) compared to the CT. In the CT group, the WBV had no effect on TBARS (P=0.559) and FRAP...

ABSTRACT Acerola is a tropical fruit that stands out for its high content of ascorbic acid and phenolic compounds. However, there is currently a lack of information on the effects of the preparation and domestic storage of fruit juices, especially that of acerola. The objective of this work was to evaluate the effect of different liquefying times (10, 30 and 50 s) and cold storage at 4 °C for 0, 24, 48 and 72 h in domestic acerola juice. In relation to such, physicochemical determinations were performed, including pH, total titratable acidity, antioxidant potential, contents of phenolic compounds and total flavonoids in juices produced from the whole fruit, the pulp and acerola seed extracts. Whole fruit juice, liquefied for 10 s, had the highest pH and...

A região dos Cerrados brasileiro forneceu, durante a última metade do século XX e as duas primeiras décadas do século atual, parte significativa das terras destinadas à expansão da fronteira agrícola no País. Dos 110 milhões de hectares de terras aráveis do bioma Cerrado, aproximadamente 50 milhões já estão ocupados com atividades humanas, especialmente as relacionadas a agropecuária. Parte dessa expansão deu-se sem a devida precaução com a preservação dos recursos naturais existentes, notadamente os recursos genéticos. Ciente que esta ocupação acelerada favoreceria o processo de erosão genética de cada uma das espécies do bioma, acarretando perdas irreparáveis para o desenvolvimento agronômico das mesmas, a equipe de pesquisadores da Embrapa Cerrados...

Domestication and Temperature Modulate Gene Expression Signatures and Growth in the Australasian Snapper     Chrysophrys auratus
Provedor de dados: 5
Autores: Wellenreuther, Maren; Le Luyer, Jeremy; Cook, Denham; Ritchie, Peter A.; Bernatchez, Louis.
Identifying genes and pathways involved in domestication is critical to understand how species change in response to human-induced selection pressures, such as increased temperatures. Given the profound influence of temperature on fish metabolism and organismal performance, a comparison of how temperature affects wild and domestic strains of snapper is an important question to address. We experimentally manipulated temperature conditions for F1-hatchery and wild Australasian snapper (Chrysophrys auratus) for 18 days to mimic seasonal extremes and measured differences in growth, white muscle RNA transcription and hematological parameters. Over 2.2 Gb paired-end reads were assembled de novo for a total set of 33,017 transcripts (N50 = 2,804). We found...

Abstract: The biotechnological potential of yeasts associated to different habitats in Colombia has been poorly studied, especially the yeasts associated with different plant structures. Fruit pulps are interesting substrates mainly for the growth of yeast species, that can positively affect the productivity and quality of some bioeconomic species. Therefore, the objective of this study was to identify the dominant yeast species associated with mango and rose apple fruit pulps in Cali, Colombia. A total of 90 isolates were obtained, which were grouped considering their colony morphology. The D1/D2 domain of the large ribosomal RNA gene (LSU rRNA gene) or internal transcribed spacer (ITS) 1, ribosomal gene 5.8S and ITS 2 (ITS) regions of one to several...

ABSTRACT Piptadenia stipulacea (Benth.) Ducke presents slow and uneven germination due to integumentary dormancy. In addition, there are no standardized indications as to the temperature and substrate for conducting the germination test in the laboratory. Thus, the objective was to evaluate methods of dormancy overcoming, temperatures and substrates in the germination and vigor of P. stipulacea seeds. For this, two experiments were installed, the first one in a completely randomized design, with 4 replicates of 25 seeds and treatments to overcome dormancy were: immersion in water at 100 °C for 1; 2; 3; 4; 5 and 6 min; immersion in concentrated sulfuric acid (H2SO4 - 98% P.A) for 1; 4; 7; 10 and 13 min; scarification on sandpaper no 80; in the region...

Dosage Compensation throughout the Schistosoma mansoni Lifecycle: Specific Chromatin Landscape of the Z Chromosome
Provedor de dados: 5
Autores: Picard, Marion A. L.; Vicoso, Beatriz; Roquis, David; Bulla, Ingo; Augusto, Ronaldo C.; Arancibia, Nathalie; Grunau, Christoph; Boissier, Jerome; Cosseau, Celine.
Differentiated sex chromosomes are accompanied by a difference in gene dose between X/Z-specific and autosomal genes. At the transcriptomic level, these sex-linked genes can lead to expression imbalance, or gene dosage can be compensated by epigenetic mechanisms and results into expression level equalization. Schistosoma mansoni has been previously described as a ZW species (i.e., female heterogamety, in opposition to XY male heterogametic species) with a partial dosage compensation, but underlying mechanisms are still unexplored. Here, we combine transcriptomic (RNA-Seq) and epigenetic data (ChIP-Seq against H3K4me3, H3K27me3, and H4K20me1 histone marks) in free larval cercariae and intravertebrate parasitic stages. For the first time, we describe...

Autores: BOGNOLA, I. A.; MAEDA, S.; SOARES, M. T. S.; GOMES, J. B. V.
A disposição de resíduos de processo industrial é um dos grandes desafios das empresas de celulose e papel. O seu uso como insumo para o plantio florestal é uma forma interessante de disposição, uma vez que resolve o problema legal, ambiental e financeiro de disposição, ao mesmo tempo que contribui para a reposição de nutrientes retirados com a colheita florestal, reciclando nutrientes e mantendo ou melhorando a fertilidade do solo e a capacidade produtiva do sítio florestal. O objetivo desse trabalho foi estimar doses de cinza de biomassa florestal para elevar os teores de Ca, Mg, Ca+Mg e K trocáveis às faixas de teores considerados médios para o cultivo de Pinus taeda L. no oeste de Santa Catarina.

Downregulation of lncRNA CCDC26 contributes to imatinib resistance in human gastrointestinal stromal tumors through IGF-1R upregulation
Provedor de dados: 56
Autores: Yan,Jingyi; Chen,Didi; Chen,Xiaolei; Sun,Xuecheng; Dong,Qiantong; Hu,Changyuan; Zhou,Feng; Chen,Wei.
Imatinib is the first line of therapy for patients with metastatic or gastrointestinal stromal tumors (GIST). However, drug resistance limits the long-term effect of imatinib. Long non-coding RNAs (lncRNAs) are emerging as key players in regulating drug resistance in cancer. In this study, we investigated the association between lncRNA CCDC26 and IGF-1R in GIST and their involvement in drug resistance. Considering the key role of lncRNAs in drug resistance in cancer, we hypothesized that IGF-1R is regulated by lncRNAs. The expression of a series of reported drug resistance-related lncRNAs, including CCDC26, ARF, H19, NBR2, NEAT1, and HOTAIR, in GIST cells treated with imatinib H19 was examined at various time-points by qRT-PCR. Based on our results and...

Abstract The filter cake from sugar cane processing is rich in organic matter and nutrients, which favors the proliferation of microorganisms with potential to deconstruct plant biomass. From the metagenomic data of this material, we assembled a draft genome that was phylogenetically related to Thermomonospora curvata DSM 43183, which shows the functional and ecological importance of this bacterium in the filter cake. Thermomonospora is a gram-positive bacterium that produces cellulases in compost, and it can survive temperatures of 60 ºC. We identified a complete set of biomass depolymerizing enzymes in the draft genome of Thermomonospora sp. CIT 1, such as α-amylase, catalase-peroxidases, β-mannanase, and arabinanase, demonstrating the potential of this...

Driblando riscos no campo.
Provedor de dados: 14
Autores: LOPES, M. A.
Gestão de riscos no campo é tema estratégico para o Brasil, uma vez que grande parte das nossas atividades agropecuárias é desenvolvida a céu aberto, exposta a todo tipo de incertezas. Tais pressões possuem efeitos multiplicadores que se propagam muito além das lavouras e criações, devido a impactos na renda, no abastecimento, na redução de empregos e na arrecadação de impostos. Por isso, falhas na gestão de riscos no campo podem levar a severos prejuízos na produção de bens que afetam muitos outros componentes da economia, além de agravar situações de pobreza e exclusão nas regiões mais pobres. Felizmente o Brasil está dando passos sólidos nessa direção. Para superar essa dificuldade, a Embrapa mobilizou uma grande rede de parceiros e integrou volumes...

Provedor de dados: 21
Autores: Johanssen, Juni Rosann E.; Sørheim, Kristin.
NORSØK fikk i oppdrag fra Regelverksutvalget for økologisk landbruk å undersøke om det er forhold i økologiske driftssystemer for slaktekyllingproduksjon som kan bidra til å redusere risikoen for sykdom med påfølgende antibiotikabehandling, og samtidig imøtekomme krav om økt andel egenprodusert fôr og utfasing av konvensjonelle proteinfôrmidler. I Norge er det liten økologisk fjørfeproduksjon, men fjørfe er husdyret som har størst forskjell i dyrevelferd når man sammenligner økologisk og konvensjonell produksjon. NORSØK har vurdert velferd hos produsenter med økologisk slaktekylling, intervjuet produsenter, sendt ut spørreskjema til andre aktører og gjennomført litteraturstudie.

Evaluating the causes and consequences of dominance by a limited number of taxa in phytoplankton communities is of huge importance in the current context of increasing anthropogenic pressures on natural ecosystems. This is of particular concern in densely populated urban areas where usages and impacts of human populations on water ecosystems are strongly interconnected. Microbial biodiversity is commonly used as a bioindicator of environmental quality and ecosystem functioning, but there are few studies at the regional scale that integrate the drivers of dominance in phytoplankton communities and their consequences on the structure and functioning of these communities. Here, we studied the causes and consequences of phytoplankton dominance in 50...

Autores: Kıran,Servinç; Furtana,Gökçen Baysal; Talhouni,Manar; Ellialtıoğlu,Şeküre Şebnem.
ABSTRACT Different responses of two melon (Cucumis melo L.) genotypes (Şemame, drought and salt-tolerant and Ananas, drought and salt-sensitive) to drought stress with or without humic acid (HA) treatment were studied. The experiment was carried out under greenhouse conditions. The experimental design was two factorial randomized block with 4 replicates. HA treatment increased the shoot fresh and dry weights and leaf area of both genotypes under drought stress. HA stimulated accumulation of K and Ca ions, chlorophyll (SPAD value) and antioxidant enzyme activity (superoxide dismutase-SOD, catalase-CAT and glutathione reductase-GR) in both genotypes. This effect was more clear in the Şemame genotype than in Ananas.As a result, HA treatment has been proved to...

Of interest of everyone, health is not an easy concept to figure out. Although there is no universal definition of health, its various uses and meanings allow us to specify its biological, psychic and social dimensions. In animal health, the biological dimension remains the most studied, there is therefore no consensual definition of international animal health. So how to understand the health of marine shellfish? A living being can be functionally described in physiopathology by monitoring biomarkers under laboratory conditions. In men and many animals, "normal" biomarker values have been proposed; these have been determined by carrying out measurements or observations in samples of healthy populations, the rigorous selection of these populations and...

The recent discovery of Pacific oyster Crassostrea gigas (also known as Magallana gigas) spatfields in a Mediterranean lagoon intensely exploited for shellfish farming (Thau lagoon) revealed significant contrasts in spatial patterns of recruitment. We evaluated the processes that drive spatial patterns in oyster recruitment by comparing observed recruitment, simulated hydrodynamic connectivity and ecological variables. We hypothesized that spatial variability of recruitment depends on (1) hydrodynamic connectivity and (2) the ecology of the larval supply, settlement, metamorphosis, survival and biotic environmental parameters. We assessed recruitment at 6-8 experimental sites by larval sampling and spat collection inside and outside oyster farming areas...

ABSTRACT The dual-stage sugar substitution technique (D3S) was used to induce sugar replacement in mango. It involved two stages, in which high-calorie sugars were partially removed from the fruit samples in the first stage and, in the second one, low-calorie sugar was incorporated into the mango. Ultrasonic waves can be applied in one or both stages and their use was also evaluated in this study. Results showed that submitting samples to ultrasonic waves (25 kHz) in both stages and their immersion in Stevia-based solution (250 or 500 g kg-1) in the second stage for 10, 20 and 30 min of processing gave higher water loss during the process, while greater solids gain could be achieved by applying ultrasound only in the first stage. Samples were also...

Dungeons and Dragons: two new species and records of Kinorhyncha from anchialine cenotes and marine lava tubes
Provedor de dados: 5
Autores: Sánchez, Nuria; Martínez, Alejandro.
Caves are natural laboratories to investigate evolutionary processes in the ocean. In contrast to the many described lineages of cave exclusive crustaceans and annelids, very little is known about cave scalidophorans. We here describe two new species of kinorhynchs from a lava tube in the Canary Islands and a cenote in the Yucatan Peninsula. Leiocanthus bretti sp. nov., from Tenerife, is mainly characterized by the lack of middorsal structure specializations on all trunk segment, middorsal line covered by hairs on segments 3-9, unpaired paradorsal setae on segments 2–9, middorsal seta on segment 10, and laterodorsal setae on segments 2–9 and 11. Pycnophyes kukulkan sp. nov. from Yucatan is defined by the strong denticulation in the tergal anterior margin,...

Düngungsstrategien im ökologischen Gemüsebau
Provedor de dados: 21
Autores: Perkons, Ute.
Futterleguminosen sind aufgrund ihrer Humusreproduktion und symbiotischen Stickstofffixierleistung die tragenden Elemente der Fruchtfolgegestaltung im Ökologischen Landbau. Der hohe Stickstoffbedarf gemüsebaulicher Kulturen wird derzeit meist über Zukaufdünger gedeckt, diese sind jedoch meist Reststoffe der konventionellen Tierhaltung. Vor diesem Hintergrund wird geprüft, inwieweit sich der Einsatz von Zukaufdüngern reduzieren lässt, indem betriebseigene Leguminosen-Schnitte und Komposte (Cut &amp; Carry) zur Düngung einer intensiven Gemüse-Fruchtfolge verwendet werden. Die Ergebnisse zeigen exemplarisch für Eissalat, dass bei der Nutzung von betriebseigenem Dünger in Form von Luzernefrischmasse mit Zukaufdünger vergleichbare Erträge erreicht werden....

Duplex Real-Time PCR Using Sybr Green I for Quantification and Differential Diagnosis between Salmonella Enteritidis and Salmonella Typhimurium
Provedor de dados: 89
Autores: Rubio,MS; Penha Fº,RAC; Almeida,AM; Barbosa,FO; Berchieri Jr,A.
ABSTRACT The incidence of foodborne diseases caused by the genus Salmonella spp. in industrialized countries is often high in epidemiological surveys. Obtaining a rapid diagnostic test for identification of bacteria is crucial in order to rapidly implement control measures to contain bacterial spread, to reduce losses in animal production and to avoid risks from food-borne infections to human health. The aim of this study was to standardize duplex real-time PCR using SYBr Green I for differential and quantitative diagnosis of S. Typhimurium and S. Enteritidis. According to the experiment, the melting temperature of 85°C was observed for a 206bp amplified product when S. Enteritidis DNA was added to the reaction. S. Typhimurium DNA showed that the melting...

Dwarfing-canopy and rootstock cultivars for fruit trees
Provedor de dados: 94
Autores: Donadio,Luiz Carlos; Lederman,Ildo Eliezer; Roberto,Sergio Ruffo; Stucchi,Eduardo Sanches.
Abstract  As fruit trees generally have a large size, the production of small or even dwarf trees is of great interest for most of fruit crops. In this review, some of the main tropical, subtropical and temperate fruit trees that have small or even dwarfing cultivars are approached. The causes of dwarfism, although the use of dwarfing rootstocks, is the main theme of this review. The factors that affect the size of the fruit trees are also approached, as well the dwarf cultivars of banana, papaya and cashew, and the dwarf rootstocks for guava, mango, anonaceae, loquat, citrus, apple and peach trees.

Dynamic interaction between basin redox and the biogeochemical nitrogen cycle in an unconventional Proterozoic petroleum system
Provedor de dados: 5
Autores: Cox, Grant M.; Sansjofre, Pierre; Blades, Morgan L.; Farkas, Juraj; Collins, Alan S.
Precambrian hydrocarbons and their corresponding source rocks are distinctly different from their Phanerozoic counterparts, having been deposited in persistently anoxic environments in ecosystems dominated by bacteria. Here, we show that cyclic enrichment of organic matter in the world's oldest hydrocarbon play (ca. 1.38 Ga), is not associated with flooding surfaces and is unrelated to variations in mineralogy or changes in the relative rate of clastic to biogenic sedimentation-factors typically attributed to organic enrichment in Phanerozoic shales. Instead, the cyclic covariation of total organic carbon, delta N-15, delta C-13 and molybdenum are explained by the feedback between high levels of primary productivity, basin redox and the biogeochemical...

Dynamic storage of glacial CO2 in the Atlantic Ocean revealed by boron [CO32-] and pH records
Provedor de dados: 5
Autores: Chalk, T. B.; Foster, G. L.; Wilson, P. A.
The origin and carbon content of the deep water mass that fills the North Atlantic Basin, either Antarctic Bottom Water (AABW) or North Atlantic Deep Water (NADW) is suggested to influence the partitioning of CO2 between the ocean and atmosphere on glacial-interglacial timescales. Fluctuations in the strength of Atlantic meridional overturning circulation (AMOC) have also been shown to play a key role in global and regional climate change on timescales from annual to millennial. The North Atlantic is an important and well-studied ocean basin but many proxy records tracing ocean circulation in this region over the last glacial cycle are challenging to interpret. Here we present new B/Ca-[CO32-] and boron isotope-pH data from sites spanning the North...

Autores: Marques, Raquel; Darnaude, Audrey M.; Schiariti, Agustin; Tremblay, Yann; Molinero, Juan-carlos; Soriano, Solenn; Hatey, Elise; Colantoni, Sébastien; Bonnet, Delphine.
For many jellyfish, the magnitude and timing of medusae blooms are recognized to result from the benthic stage dynamics. However, information on the scyphistomae of jellyfish populations in the wild remains scarce. Here, bi-mensual underwater photoquadrat surveys were combined with scyphistomae sampling and observation to describe the annual (February 2017–January 2018) benthic stage dynamics and asexual reproduction strategy of Aurelia coerulea in the Thau lagoon (43°25′31.1″N; 03°42′0.9″E). Our results revealed unexpected seasonal patterns of variation: scyphistoma coverage peaked in the spring (11.6 ± 3.7% on 21st April) and was minimal in the summer and autumn (1.4 ± 1.3% on 10th October). The increase in scyphistoma coverage mainly resulted from an...

Dynamics and control of a periodically forced microalgae culture
Provedor de dados: 5
Autores: Martínez, Carlos; Mairet, Francis; Martinon, Pierre; Bernard, Olivier.
Microalgae cultivation with wastewater is a promising way of reducing the energetic needs for wastewater treatment and the costs of biofuel production. However, the very turbid medium is not favorable for the development of microalgae. Indeed, light, the key element for photosynthesis, rapidly vanishes along depth due to absorption and scattering. Therefore it is crucial to understand the effects of the depth on turbid cultures. In this work, we study theoretically the long-term behavior of a continuous culture of microalgae exposed to a periodic source of light. By allowing periodic variations of the depth and the hydraulic retention time, we show that the microalgae population is forced to a periodic regime. Finally, we address numerically the problem of...

Dynamics and stability of Marandu grass tillers in monocrop systems and babassu palm silvopastoral systems
Provedor de dados: 1
Autores: Araújo, Ricardo Alves de; Rodrigues, Rosane Cláudia; Costa, Clésio Santos; Santos, Francisco Naysson Sousa; Lima, Antonio José Temístocles; Rodrigues, Marcônio Martins.
&amp;nbsp;This study aimed to evaluate the dynamics, population density of tillers and stability index of Urochloa brizantha in silvopastoral systems composed of babassu palm trees in the Pre-Amazon region. Four systems consisting of different densities of palm trees (80, 131, and 160 palms ha-1) and a monocrop were evaluated. The rates at which the basal tillers appeared in systems with 131 and 160 palms ha-1 were similar to each other and were slower compared to the monocrop pasture and the system with 80 palms ha-1. Despite the variations, the stability index was always higher than 1.0, which infers a compensatory mechanism between tiller appearance and mortality rate, since monocrop pastures and systems with 80 palms ha-1 have a higher rate of tissue...

Dynamics of benthic metabolism, O2, and pCO2 in a temperate seagrass meadow
Provedor de dados: 5
Autores: Berg, Peter; Delgard, Marie Lise; Polsenaere, Pierre; Mcglathery, Karen J.; Doney, Scott C.; Berger, Amelie C.
Seagrass meadows play an important role in “blue carbon” sequestration and storage, but their dynamic metabolism is not fully understood. In a dense Zostera marina meadow, we measured benthic O2 fluxes by aquatic eddy covariance, water column concentrations of O2, and partial pressures of CO2 (pCO2) over 21 full days during peak growing season in April and June. Seagrass metabolism, derived from the O2 flux, varied markedly between the 2 months as biomass accumulated and water temperature increased from 16°C to 28°C, triggering a twofold increase in respiration and a trophic shift of the seagrass meadow from being a carbon sink to a carbon source. Seagrass metabolism was the major driver of diurnal fluctuations in water column O2 concentration and pCO2,...

ABSTRACT: Maintenance of straw on the soil surface in sugarcane production areas can influence weed occurrence and herbicide dynamics. After application, considerable losses of clomazone can occur as a result of its physicochemical characteristics. For this reason, novel formulations have been developed. In addition to the conventional formulation, microencapsulated formulations are currently available. Thus, the aim of this study was to observe and compare the effect of clomazone formulations under different application conditions. For this purpose, the experiment was carried with 12 treatments in a completely randomized design, with four replications, using clomazone formulations (1,200 g a.i. ha-1), on soils with different moisture levels, in the...

ABSTRACT We analyzed the botanical knowledge of the Laklãnõ-Xokleng people in the Ibirama Laklãnõ Indigenous Territory. They are the last remnant of this ethnicity living in a unitary socio-political organization. The objective was to investigate the dynamics, distribution and transmission of botanical information. We interviewed 112 people in two villages about known and used plants. Data were collected through structured socioeconomic questionnaires, free lists and walk-in-the-woods tours. Data were analyzed using descriptive statistics and metrics of social network analysis. Of the 314 plants mentioned in the interviews, 77 % were currently used, 15 % were used in the past, and 8 % were known but never used. Men cited more plants than women. We found no...

The oxygen minimum zone (OMZ) of Peru is recognized as a source of CO2 to the atmosphere due to upwelling that brings water with high concentrations of dissolved inorganic carbon (DIC) to the surface. However, the influence of OMZ dynamics on the carbonate system remains poorly understood given a lack of direct observations. This study examines the influence of a coastal Eastern South Pacific OMZ on carbonate system dynamics based on a multidisciplinary cruise that took place in 2014. During the cruise, onboard DIC and pH measurements were used to estimate pCO2 and to calculate the calcium carbonate saturation state (Ω aragonite and calcite). South of Chimbote (9°S), water stratification decreased and both the oxycline and carbocline moved from 150 m depth...

Infectious agents such as the bacteria Vibrio aestuarianus or Ostreid herpesvirus 1 (OsHV‐1) have been repeatedly associated with dramatic disease outbreaks of Crassostrea gigas beds in Europe. Beside roles played by these pathogens microbial infections in C. gigas may derive from the contribution of a larger number of microorganisms than previously thought, according to an emerging view supporting the polymicrobial nature of bivalve disease. In this study, the microbial communities associated with a large number of C. gigas samples collected during recurrent mortality episodes at different European sites were investigated by real‐time PCR and 16SrRNA gene‐based microbial profiling.

The knowledge of suspended particulate matter (SPM) and turbidity dynamics in coastal waters is essential for studying marine ecosystems. Flocculation/deflocculation processes are crucial mechanisms controlling the dynamics of SPM physical characteristics and thus, the fate of these SPM in the environment. This PhD thesis focuses on the SPM characteristics and their dynamics in coastal waters, from tidal to annual scales, in response to hydrodynamic, hydrological and biological forcing that take place at the interface between estuaries and coastal seas. To this end, optical and acoustic sensors were deployed in situ through 6 field campaigns in 2016, in order to characterize and quantify SPM in the water column, near the mouth of the Seine estuary...

In the seas of southern Europe, Mnemiopsis leidyi is responsible for invasive events with worrying ecological consequences. Since 2005, this native of the east coast of the Americas is regularly observed in the English Channel in the Bay of Seine. In order to find out whether changes have taken place in the distribution of M. leidyi in the English Channel since the first reports made before 2014 and to identify the environmental conditions favourable to his presence, hydrological data and Channel Ground Fish Survey from 2014 to 2015 were analyzed. This confirmed that M. leidyi is well established in the Bay of Seine (naturalized species) but does not extend outside this area and therefore cannot be considered an invasive species for that region.

Autores: Rehman, Tanzeel; Khan, Muhammad Usman.
During the last five decades Asia has made considerable development in the field of agricultural machinery. During the year 1960 the condition of mechanization was very poor and most of the farm operations were performed manually. A positive correlation between the farm power availability and the productivity was observed during past 3 decades for several Asian nations including China, Pakistan, India, and Bangladesh. The previous trends have shown that the Pakistan, India and Bangladesh have experienced only the selective farm mechanization which was found to be initially limited to the use of heavy tractors only. In addition to the full-scale tractors, China, India and Bangladesh have adopted the power tillers and small-scale tractors to co-op with the...

Early use of polymyxin B reduces the mortality of carbapenem-resistant Klebsiella pneumoniae bloodstream infection
Provedor de dados: 55
Autores: Liang,Qiqiang; Huang,Man; Xu,Zhijiang.
ABSTRACT Polymyxin B is one of the last resort option for carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infection in China. Therefore, the timing of administration of polymyxin is frequently delayed. We collected 40 cases of CRKP bloodstream infections (BSIs) treated with combinations based on polymyxin B over 30 months. The primary outcome, 30-day mortality rate, was 52.5% (21/40). Early administration of polymyxin B is meant to administer the drug within 48 h of diagnosing bacteremia. Delayed administration was considered when polymyxin B was administered after 48 h of bacteremia onset. Polymyxin B duration and total dosages were similar in the two groups (11.57 days versus 11.76 days, p = 0.919; 1306.52 mg versus 1247.06 mg, p = 0.711)....

Shallow hydrothermal vents are of pivotal relevance for ocean biogeochemical cycles, including seawater dissolved heavy metals and trace elements as well as the carbonate system balance. The Kueishan Tao (KST) stratovolcano off Taiwan is associated with numerous hydrothermal vents emitting warm sulfur-rich fluids at so-called White Vents (WV) and Yellow Vent (YV) that impact the surrounding seawater masses and habitats. The morphological and biogeochemical consequences caused by a M5.8 earthquake and a C5 typhoon ("Nepartak") hitting KST (12th May, and 2nd-10th July, 2016) were studied within a 10-year time series (2009-2018) combining aerial drone imagery, technical diving, and hydrographic surveys.

Large continental faults extend for thousands of kilometres to form boundaries between rigid tectonic blocks. These faults are associated with prominent topographic features and can produce large earthquakes. Here we show the first evidence of a major tectonic structure in its initial-stage, the Al-Idrissi Fault System (AIFS), in the Alboran Sea. Combining bathymetric and seismic reflection data, together with seismological analyses of the 2016 Mw 6.4 earthquake offshore Morocco – the largest event ever recorded in the area – we unveil a 3D geometry for the AIFS. We report evidence of left-lateral strike-slip displacement, characterise the fault segmentation and demonstrate that AIFS is the source of the 2016 events. The occurrence of the Mw 6.4 earthquake...

Eastern Mediterranean salinification observed in satellite salinity from SMAP mission
Provedor de dados: 5
Autores: Grodsky, Semyon A.; Reul, Nicolas; Bentamy, Abderrahim; Vandemark, Douglas; Guimbard, Sebastien.
One of the saltiest seas, the Mediterranean, experiences significant salinity variations in near surface layers. Satellite sea surface salinity (SSS) data obtained using Soil Moisture Active Passive (SMAP) mission indicate steady salinification of the eastern Mediterranean Levantine Basin at a rate of ~0.14 psu/year during 2015–2018. Satellite-observed salinity changes are confirmed by Argo float data and suggest possible changes in properties of the Levantine Intermediate Water. Eastern Mediterranean salinification often coincides with a freshening of the western Ionian Sea. Based on satellite altimetry geostrophic currents, these salinity changes are concurrent with a weakening cyclonic circulation in the Levantine Basin and strengthening anticyclonic...

Autores: Alvarez,Leopoldo Jesús; Zamudio,Fernando; Melo,Maria Cecilia.
Abstract In this study, we record for the first time the genus Notocyrtus (Heteroptera, Reduviidae) from Argentina based on three species: Notocyrtus dorsalis (Gray), Notocyrtus dispersus Carvalho &amp; Costa, and Notocyrtus foveatus Stål. We also describe and illustrate a mimetic complex comprising the three Notocyrtus species and Tetragona clavipes (Fabricius) (Apidae, Meliponini), that were collected on Bahuinia forficata Link (Leguminosae: Caesalpinioideae). We include biological comments on the plant-reduvid-bee interaction and hypothesize about the functionality of the mimetic complex described.

Autores: Grovermann, Christian; Wossen, Tesfamicheal; Müller, Adrian; Nichterlein, Karin.
Agricultural innovation is an essential component in the transition to more sustainable and resilient farming systems across the world. Innovations generally emerge from collective intelligence and action, but innovation systems are often poorly understood. This study explores the properties of innovation systems and their contribution to increased eco-efficiency in agriculture. Using aggregate data and econometric methods, the eco-efficiency of 79 countries was computed and a range of factors relating to research, extension, business and policy was examined. Despite data limitations, the analysis produced some interesting insights. For instance public research spending has a positive significant effect for emerging economies, while no statistically...

Autores: Andersson, Andreas J.; Venn, Alexander A.; Pendleton, Linwood; Brathwaite, Angelique; Camp, Emma; Cooley, Sarah; Gedhill, Dwight; Koch, Marguerite; Maliki, Samir; Manfrino, Carrie.
The Caribbean and Western Atlantic region hosts one of the world’s most diverse geopolitical regions and a unique marine biota distinct from tropical seas in the Pacific and Indian Oceans. While this region varies in human population density, GDP and wealth, coral reefs, and their associated ecosystem services, are central to people’s livelihoods. Unfortunately, the region’s reefs have experienced extensive degradation over the last several decades. This degradation has been attributed to a combination of disease, overfishing, and multiple pressures from other human activities. Furthermore, the Caribbean region has experienced rapid ocean warming and acidification as a result of climate change that will continue and accelerate throughout the 21st century....

Ecological model of the Bay of Biscay and English Channel shelf for Environmental Status assessment Part 1: Nutrients, phytoplankton and oxygen
Provedor de dados: 5
Autores: Menesguen, Alain; Dussauze, Morgan; Dumas, Franck; Thouvenin, Benedicte; Garnier, Valerie; Lecornu, Fabrice; Repecaud, Michel.
European directives (Water Framework Directive - WFD and Marine Strategy Framework Directive - MSFD) require a regular survey of several descriptors of the Environmental Status of coastal waters of the North-east Atlantic Ocean. Especially for the MSFD, which may concern large continental shelf areas where measurements are scarce, realistic ecological models can help assessing the Environmental Status. The ECO-MARS3D model of the pelagic ecosystem of the Bay of Biscay and English Channel continental shelf (NE Atlantic) has been developed for these applied purposes and validated against various types of historic data. This first paper deals with the basic biogeochemical version, which contains inorganic nutrients (NH4, NO3, PO4, Si(OH)4), three...

Ecological niche differentiation between Acanthodactylus micropholis and A. khamirensis (Sauria: Lacertidae) in southern Iran
Provedor de dados: 103
Autores: Heidari,Nastaran.
ABSTRACT Acanthodactylus micropholis Heidari, Rastegar-Pouyani, Rastegar-Pouyani &amp; Rajabizadeh, 2013 and A. khamirensis Blanford, 1874 are genetically and morphologically distinct, but their ecological differentiation has not previously been evaluated. The ecological niche models of these two sister species Acanthodactylus were reconstructed using climate and geographical data. Species distribution modeling for A. micropholis and A. khamirensis was used to make predictions and showed that most parts of southern and southeastern Iran are suitable for the distribution of both species. Habitat suitability was mostly dependent upon minimum temperature of the coldest month and seasonal precipitation for A. micropholis and A. khamirensis, respectively. Niche...

Abstract: Invasive species need a closer look on the threats they may cause to the environment, mainly considering the scenario of climatic changes predicted for the next decades. Schinus molle is a pioneer tree native from South America, reported as an important invasive species in four continents. Using ecological niche modeling we show that a wide area over the world is propitious for S. molle establishment under current climatic conditions, including 14 of the 25 world’s biodiversity hotspots. Current projections of climate changes suggest scenarios implying the rise of areas favorable for S. molle expansion. Therefore, particular attention should be taken in regions where it was introduced, while approaches for long-term intervention may be necessary...

Background Nematodes are an important component of deep-sea hydrothermal vent communities, but only few nematode species are able to cope to the harsh conditions of the most active vent sites. The genus Oncholaimus is known to tolerate extreme geothermal conditions and high sulphide concentrations in shallow water hydrothermal vents, but it was only occasionally reported in deep-sea vents. In this study, we performed morphological, genetic and ecological investigations (including feeding strategies) on an abundant species of Oncholaimus recently discovered at Lucky strike vent field on the Mid-Atlantic Ridge at 1700 m water depth. Results We described this species as Oncholaimus dyvae sp. nov.. This new species differs from all other members of the genus...

ECONOMIC ANALYSIS OF DIFFERENT HYDRAULIC SPRAYERS USED IN SUGARCANE (Saccharum spp.)
Provedor de dados: 70
Autores: Santos,Neisvaldo B. dos.
ABSTRACT Brazil is the largest sugarcane producer worldwide. In mills, sugarcane crops are sprayed with agrochemicals using self-propelled, tractor-driven, and aerial hydraulic sprayers. As sugarcane spraying is regularly performed over extensive areas, the machinery to be used should be planned and dimensioned to ensure timely operations without overloading and at lower costs. Therefore, the current study aimed to analyze the operational and economic performances of different hydraulic sprayers to perform sugarcane crop control. As long as meeting our goal in field conditions would be difficult, we opted to develop a computational model, named as “TratoCana”, using a spreadsheet and programming language. The model was used to assess economic and...

Autores: BERSELI,C.; BONO,J.A.M.; SANTOS,S.A.; PEREIRA,F.A.R.; REIS NETO,J.F.
ABSTRACT: Pantanal plain has large extensions of land formed by many types of landscapes suitable to extensive livestock system. Open grasslands and lowlands are formed by forage such as grasses and forbs widely consumed by cattle. However, climatic and human factors can promote the dissemination of invasive shrub species such as canjiqueira (Byrsonima cydoniifolia A. Juss) making it necessary, in many cases, the human intervention to control the invasion. The present work had as objective to determine the economic threshold level to control canjiqueira through two methods: tractor driven blade and link chains pulled by tractor in different invasion levels plants per hectare. Economic Threshold proved to be a tool for efficient and effective management for...

The deep-sea benthic ecosystems of the French Kerguelen exclusive economic zone remain poorly understood. To address benthic conservation issues, the authors recently contributed expert knowledge to guide the recent extension of the Marine Reserve of the ‘Terres australes françaises’. In this new study, we propose a benthic ecoregionalisation of the northern Kerguelen Plateau based on a measurable and repeatable methodology that relies on the generalised dissimilarity modelling technique. Data of macro-epibenthic invertebrate species from the POKER 2 (2010) fish stock assessment survey have been used to compute the models. Our results allow us (i) to characterise and map benthic landscape units based on assemblages of marine invertebrates pooled by taxa...

ABSTRACT Pork is the most consumed animal protein around the world. The production levels are significant, which results in the generation of large amounts of slaughter waste. Such waste is often disposed of improperly in agricultural areas, causing environmental imbalance by the contamination of soil and water sources with metals and pathogenic organisms. This study evaluates the phytotoxic effects of pig slaughterhouse waste in natura and after stabilization processes on lettuce (Lactuca sativa Linnaeus, 1753), radish (Raphanus sativus Linnaeus, 1753), and rice (Oryza sativa Linnaeus, 1753), in addition to shoot nutrient contents. To do this, the waste was evaluated through phytotoxicity tests on lettuce, radish, and rice plants in natura (PSWin) as well...

Educar, concientizar, transferir, dialogar... ¿qué es y para qué sirve la extenisón rural?
Provedor de dados: 194
Autores: Otero, Jeremías; Selis, Dardo Héctor.
La Extensión Rural (ER) ha presentado a lo largo de su historia, variaciones en su concepción, función y finalidad. Más allá de la clásica distinción entre el enfoque transferencista y la propuesta dialoguista de Paulo Freire, existen matices y otras vertientes que permiten enriquecer la comprensión del asunto. A fin de reconstruir esa diversidad, el trabajo propone una reflexión sobre los enfoques de ER a través del análisis de más de 20 definiciones. Qué es la extensión rural, qué función cumple y qué fin persigue, son tres dimensiones que permitieron organizar nuestro análisis y reflexión.

Autores: FIGUEROA GUALTEROS,Ana María; CASTRO TRIVIÑO,Edgar Alejandro; CASTRO SALAZAR,Hans Thielin.
RESUMEN El maíz es el segundo cereal de mayor producción en Colombia con un 21,9 % de la superficie total. La plaga Spodoptera frugiperda ataca la planta desde las primeras semanas de crecimiento, devorando sus hojas, tallo y granos; disminuyendo el rendimiento de los cultivos. Esta plaga se controla con el uso indiscriminado de plaguicidas sintéticos como: carbofurano, clorpirifos y atrazina. En esta investigación, los extractos de Azadirachta indica, Piper nigrum, Petiveria alliacea y sus mezclas; y los extractos de Nicotiana tabacum, Lippia alba, Allium sativum y sus mezclas se aplicaron como bioplaguicidas en plantas de maíz amarillo tradicional. Después de la tercera semana de crecimiento, los tratamientos se aplicaron dos veces al día cada tres días...

RESUMEN El mejoramiento genético convencional en frijol común resulta difícil debido a que presenta una base genética estrecha y muy estable. En este sentido, la combinación de la mutagénesis y el cultivo de tejidos, es una alternativa para inducir variabilidad genética en la búsqueda de tolerancia a factores bióticos y abióticos. Es por ello, que el presente trabajo tuvo como objetivo determinar el efecto de diferentes explantes irradiados en la regeneración in vitro de frijol común (Phaseolus vulgaris L.) cultivar "ICA Pijao". Se aplicaron radiaciones gamma en callos, en el nudo cotiledonal con un cotiledón (NC-1) con dosis de 0, 10, 20, 30, 40, 50 y 60 Gy y semillas con 0, 100, 200, 300 y 400 Gy. Se evaluó el porcentaje de germinación, longitud de las...

Provedor de dados: 14
Autores: MARTINS, P. Y. F.; PINHEIRO, R. R.; CAVALCANTE, A. C. R.
Resumo: Resumo: A linfadenite caseosa é uma das principais enfermidades bacterianas de caprinos e ovinos. Os abscessos causados pela doença apresentam alta concentração do agente. Quando não tratados antes do rompimento, levam à grande contaminação ambiental e aumento de casos no rebanho. O objetivo deste trabalho foi avaliar a eficácia da cal hidratada, desinfetante de baixo custo e fácil aplicação, na eliminação de Corynebacterium pseudotuberculosis em ambientes simulados. Para tanto, a cal foi aplicada em duas apresentações (pó e a 40%), sob duas condições de umidade (35% e 100%) e em dois tipos de superfícies (lisa e rugosa). A umidade relativa do ar elevada manteve a pintura de cal úmida por mais tempo, tendo sido removida mais facilmente em contato...

Provedor de dados: 196
Autores: Silva, Esdras Henrique da; Campos, Vicente Paulo; Rocha, Fernando da Silva; Zeviani, Walmes Marques; Terra, Willian César; Rigitano, Renê Luís de Oliveira.
Ovos, juvenis de segundo estádio (J2) e fêmeas de Meloidogyne incognita foram inseridos em solução contendo o princípio ativo aldicarbe com ação nematicida. A exposição ao nematicida ocasionou: (1) redução na eclosão, (2) redução na mobilidade, (3) mortalidade de J2, e (4) redução na penetração. A aplicação do nematicida após a infecção com J2 saudáveis foi mais eficiente em reduzir a reprodução do nematoide. A aplicação feita mais próxima da inoculação causou maiores reduções de galhas e de ovos/g de raiz de planta de soja, com maior efeito na reprodução. Enquanto os J2 incubados por 24 h em aldicarbe 50 μg mL-1 e inoculados em soja tiveram o número de ovos/g raiz reduzido em 2,5%, em comparação à testemunha, a aplicação da mesma concentração após a...

Efeito do estádio fenológico do algodoeiro na produção do feromônio de agregação do bicudo-do-algodoeiro.
Provedor de dados: 14
Autores: MAGALHÃES, D. M.; BORGES, M.; LAUMANN, R. A.; MORAES, M. C. B.
Os machos de Anthonomus grandis produzem um feromônio de agregação, composto por quatro componentes de origem terpênica, que atrai a ambos os sexos. A colonização nos algodoais se inicia com o surgimento dos botões florais e emissão de compostos orgânicos voláteis pelas plantas, e se intensifica com o feromônio liberado pelos primeiros machos que chegam à lavoura. A produção feromonal de A. grandis é influenciada por vários fatores, dentre eles, a alimentação. Contudo, os estudos até então conduzidos não avaliaram quantitativamente a taxa de emissão do feromônio, após a alimentação em diferentes estádios fenológicos e estruturas do algodoeiro. Tal informação é importante porque provaria que a fenologia da planta influencia a produção do feromônio. Assim, o...

Autores: Calciolari,K.; Gravena,K.; Bernardi,N.S.; Queiroz,D.J.; Lacerda Neto,J.C.
RESUMO As afecções do sistema respiratório são a segunda causa de queda de desempenho e afastamento dos equinos do esporte ou trabalho, as quais estão atrás somente das desordens musculoesqueléticas. A estabulação e a alimentação à base de fenos predispõem os equinos à inalação de grande número de agentes irritantes às vias aéreas. No intuito de avaliar a influência dos tipos de cama utilizados em baias, estudaram-se três grupos de cinco equinos cada, durante 45 dias. Dois grupos foram mantidos em cocheiras com forrações diferentes à base de madeira (maravalha de pínus autoclavada-MA e serragem-SE) e o terceiro grupo permaneceu no pasto. Foram realizadas avaliações quinzenais, que incluíram exame físico, hemograma, hemogasometria e lavado broncoalveolar....

Effect of asymmetric competition on distance among Myrmeleon brasiliensis (Návas, 1914) (Neuroptera: Myrmeleontidae) larvae
Provedor de dados: 3
Autores: Lima, Tatiane do Nascimento; Freire, Luciane Gomes; Lima, Dariany Cristina Aristides de.
In cases of asymmetric competition, larger individuals of many animal species have a greater probability of acquiring territory, gaining initial access to resources and finding a mate in comparison to smaller individuals. The competition among larvae of the antlion Myrmeleon brasiliensis (Neuroptera, Myrmeleontidae) is observed in the search for space for the construction of traps, in the forage for prey, and in the occurrence of cannibalism. The body size of the larvae is proportional to the size of the traps and the success of predation. Thus, larger specimens are better competitors in terms of capturing preys (asymmetric competition). The aim of the present study was to determine the effects of asymmetric competition in M. brasiliensis regarding the...

First colostrum is an important source of nutrients and immune factors which are necessary for calves in the first weeks of life. Despite these benefits, colostrum can also represent one of the earliest potential exposures of dairy calves to infectious agents which these patogens can act directly on growth and cause diseases such as scours or septicemia. With recent increased interest in pasteurized milk feeding systems, producers have been curious to learn if there may also be benefits from feeding pasteurized colostrum. This study was realized to determine the effects of feeding heat-treated colostrum or unheated colostrum on passive transfer of immunity, immunoglobulin G (IgG) concentration, total plate count, health and performance of neonatal dairy...

Effect of fish bones and algae fibre as fertilisers for ryegrass
Provedor de dados: 21
Autores: Ahuja, Ishita; Løes, Anne-Kristin.
In organic growing, both in Norway and elsewhere in Europe, significant amounts of fertiliser products not derived from certified organic farming are used, such as dried poultry manure or other types of fertilisers derived from conventional farms such as animal by-products. Organic agriculture aims to be independent of conventional agriculture, and fertilisers derived from harvesting of natural materials may be a relevant alternative. Catching of wild fish, and collection or cultivation of seaweeds, result in residual products which contain essential plant nutrients. Sediments of fish bones, which are residues from hydrolysis of fish remains used to produce fish oil and soluble proteins, are rich in nitrogen and phosphorus. Residues from seaweeds (algae...

EFFECT OF HEIGHT, TILT AND TWIST ANGLES OF AN ACTIVE REFLECTANCE SENSOR ON NDVI MEASUREMENTS
Provedor de dados: 70
Autores: Stocker,Vinícius; Souza,Eduardo G. de; Johann,Jerry A.; Beneduzzi,Humberto M.; Silva,Franciléia de O. e.
ABSTRACT The application of nitrogen (N) fertilizer is complex and expensive, so its correct management has financial and environmental benefits. The use of optical proximity sensors is a promising technique. However, the movement of the agricultural machinery or of the person carrying the sensor will result in height differences and/or different tilt and twist angles with respect to the canopy. We considered whether these variations would affect the reflectance measurement. In this study, we took normalized difference vegetation index (NDVI) readings of a wheat canopy, to which 90 kg ha-1 of urea had been applied in stage 5, and observed the NDVI in stages 6, 8 and 10.5. We also tested soybeans, to which 90 kg ha-1 of urea had been applied in stage R1,...

The research focused on the following traits: age at slaughter (days), live weight at slaughter (kg), growth rate (kg day−1), and morphometric testicle traits (volume, cm3; weight, g; length, width, thickness, and circumference, mm). The efficacy of immunocastration was determined based on androstenone and skatole levels in adipose tissue. The group of immunocastrated animals had higher body weight at slaughter (+18.8 kg) due to higher average daily live gain (+87 g). Immunocastration resulted in reduced...

ABSTRACT The production of inoculum from arbuscular mycorrhizal fungi (AMF) at a large scale and low cost is essential for establishing methods to assist in producing pineapple plantlets with high nutritional and phytosanitary quality. However, this objective is difficult to accomplish because of the biotrophic nature of these fungi. The on-farm multiplication method for AMF inoculum presents a good alternative to supply the demand for the production of glomerospores. This study aimed to multiply and evaluate AMF inoculum originating from isolated species (including Rhizophagus clarus, Claroideoglomus etunicatum) versus native AMF from pineapple and coffee plantations multiplied by the on-farm method on the colonization in pineapple plantlets. Initially,...

Autores: AVIARA, NDUBISI A.; Iyilade, Idowu J.; Oyeniyi, Samuel K.; Aremu, Ademola K.
The use of inappropriate equipment to crack bush mango nut and obtain the kernel has adversely affected the efficiency of its processing operations. The manual method, which involves cracking the nut with stone or pestle and mortar, is not only slow and risky, but also wasteful. In order to develop appropriate processing equipment for the nut, knowledge of its mechanical properties is necessary. This study was undertaken to determine some strength properties of the nut at different moisture contents under lateral and longitudinal loading orientations, using Universal Testing Machine (UTM). In the moisture range of 7.52% - 20.6% (d.b) under both lateral and longitudinal loading orientations, results of tests showed that all the strength properties (bioyield...

Abstract: In this study we described the diet of Hylaeamys megacephalus (G. Fisher, 1814) and investigated the degree of individual variation in the diet of this species among the Amazon Forest and the oil palm plantation. We analyzed the stomach contents of 36 individuals, of whom 11 were collected in the forest and 25 captured in the palm oil palm plantation. The H. megacephalus diet consisted of 18 food items, of which 12 were animal composition and eight were vegetable composition. The niche amplitude of the species was narrower in the forest area (Baforest = 0.013) compared to the palm tree plantation area (Bapalm = 0.478). This shows that individuals have greater niche overlap in forest areas, while in the plantation areas the animals expand their...

ABSTRACT: With extensive use of herbicides in agricultural areas, the risk of contamination of groundwater and surface water by these products has become a worldwide concern. Practices of application or maintenance of soil organic residues that have begun to be used in agriculture for soil nutrition have demonstrated other benefits besides nutrient supplementation, such as reduced mobility and increased soil degradation of herbicides. Because it is the final destination of herbicides, soil and its constituents, especially organic matter in tropical soils, play a prominent role in processes that encompass the dynamics of herbicide molecules. In this context, it is necessary to know the influence of the organic matter and its constituents on the behavior of...

Provedor de dados: 5
Autores: Masroor, Waliullah; Farcy, Emilie; Blondeau-bidet, Eva; Venn, Alexander; Tambutté, Eric; Lorin-nebel, Catherine.
The responses of European sea bass to temperature increase and salinity decrease were investigated measuring mRNA expression levels of main genes involved in ion transport. Juvenile fish were pre-acclimated to seawater (SW) at 18 °C (temperate) or 24 °C (warm) for two weeks and then transferred for two weeks to either fresh water (FW) or SW at the respective temperature. Unlike temperate conditions, there is no change in Na+/K+-ATPase α1a (nka α1a) and Na+/H+ exchanger 3 (nhe3) mRNA expression following FW transfer in warm conditions. This is linked to the high expression of these genes in warm SW compared to temperate SW. Na+/Cl−-cotransporter (ncc2a) expression however is increased following FW transfer in temperate and warm conditions. Main transporters...

Autores: Ferreira,Dinamarta V.; Cruz,Joseane S.; Sacramento,Jailton J.M.; Rocha,Marcos Leandro C.; Cristaldo,Paulo F.; Araújo,Ana Paula A.
ABSTRACT Laboratory bioassays should be performed under appropriate conditions that minimize stress and promote greater longevity to tested animals. For social insects, for instance, the stress triggered by removal individuals from nests may result in changes in their survival and behavior. Here we analyzed the effects of variations of different combinations of temperature and substrate moisture (mL of water/g of nest substrate) on group survival of Constrictotermes sp. (Termitidae: Nasutitermitinae). In general, lower substrate moisture resulted in faster mortality. On the other hand, groups survival longer at a temperature of 26 ºC and under higher substrate moisture (2–3 mL/7 g of nest substrate). The result of this study may contribute to the...

ABSTRACT: Eucalyptus plants are sensitive to stress during their initial development, and water deficit is the most important one. Thus, the hormetic effect caused by the application of chemical products may be a factor that allows plants to tolerate such stresses. The objective of this study was to evaluate the effects of trinexapac-ethyl on the initial growth of Eucalyptus urophylla (Clone I-144), under water deficiency, at two application timings (before planting - BP; and after planting - AP). Two experiments were conducted simultaneously in a greenhouse for 74 days after planting (DAP) eucalyptus in 15 L pots. Treatments consisted of three trinexapac-ethyl doses (0.0, 30, and 60 g a.i. ha-1) and two water conditions (with and without water deficit). A...

ABSTRACT:  Potential soil acidity can be measured by two methods in the states of Rio Grande do Sul (RS) and Santa Catarina (SC): solution SMP or solution TSM (Buffer Santa Maria). Calibration of these methods is done by incubating soils for long periods (180 days) of CaCO3. The hypothesis of this study is that it is possible to reduce the incubation period in soils by using a soluble base such as calcium hydroxide. The study aimed to estimate potential acidity in a group of soils by moist incubation with Ca(OH)2 (short) as an alternative to the typical method with CaCO3 (long) and relate to the values ​​estimated by the equation used by the Soil Chemistry and Fertility Commission of Rio Grande do Sul and Santa Catarina (CQFS-RS/SC; 2016). Ten soils with...

Provedor de dados: 56
Autores: Pazin,W.M.; Vilanova,N.; Voets,I.K.; Soares,A.E.E.; Ito,A.S.
It has been hypothesized that the therapeutic effects of artepillin C, a natural compound derived from Brazilian green propolis, are likely related to its partition in the lipid bilayer component of biological membranes. To test this hypothesis, we investigated the effects of the major compound of green propolis, artepillin C, on model membranes (small and giant unilamelar vesicles) composed of ternary lipid mixtures containing cholesterol, which display liquid-ordered (lo) and liquid-disordered (ld) phase coexistence. Specifically, we explored potential changes in relevant membrane parameters upon addition of artepillin C presenting both neutral and deprotonated states by means of small angle X-ray scattering (SAXS), differential scanning calorimetry...

Effects of atmospheric CO2 variability of the past 800 kyr on the biomes of southeast Africa
Provedor de dados: 5
Autores: Dupont, Lydie M.; Caley, Thibaut; Castañeda, Isla S.
Very little is known about the impact of atmospheric carbon dioxide pressure (pCO2) on the shaping of biomes. The development of pCO2 throughout the Brunhes Chron may be considered a natural experiment to elucidate relationships between vegetation and pCO2. While the glacial periods show low to very low values (~ 230 to ~ 190 ppmv, respectively), the pCO2 levels of the interglacial periods vary from intermediate to relatively high (~250 to ~ 270, respectively). To study the influence of pCO2 on the Pleistocene development of SE African vegetation, we used the pollen record of a marine core (MD96-2048) retrieved from Maputo Bay south of the Limpopo River mouth in combination with stable isotope and geochemical proxies. Applying endmember analysis, four...

ABSTRACT The expansion of the Amazonian agricultural frontier represents the most extensive land cover change in the world, detrimentally affecting stream ecosystems which collectively harbor the greatest diversity of freshwater fish on the planet. Our goal was to test the hypotheses that deforestation affects the abundance, richness, and taxonomic structure of headwater stream fish assemblages in the Upper Xingu River Basin, in Southeastern Amazonia. Standardized sampling surveys in replicated first order streams demonstrated that deforestation strongly influences fish assemblage structure. Deforested stream reaches had twice the fish abundance than reference stream reaches in primary forests. These differences in assemblage structure were largely driven...

Effects of dipyrone on the digestive tract
Provedor de dados: 56
Autores: Collares,E.F.; Troncon,L.E.A.
Dipyrone (metamizole), acting through its main metabolites 4-methyl-amino-antipyrine and 4-amino-antipyrine, has established analgesic, antipyretic, and spasmolytic pharmacological effects, which are mediated by poorly known mechanisms. In rats, intravenously administered dipyrone delays gastric emptying (GE) of liquids with the participation of capsaicin-sensitive afferent fibers. This effect seems to be mediated by norepinephrine originating from the sympathetic nervous system but not from the superior celiac-mesenteric ganglion complex, which activates β2-adrenoceptors. In rats, in contrast to nonselective non-hormonal anti-inflammatory drugs, dipyrone protects the gastric mucosa attenuating the development of gastric ulcers induced by a number of...

ABSTRACT English Thoroughbred horses, are widespread in Mexico and due to the lack of data on their exercise physiology, it is important to conduct exercise tests in order to obtain information the effects of exercise on more essential cations/anions in blood serum, as these horses are submitted to constant efforts. The study was carried out with 150 blood samples of English Thoroughbred horses clinically healthy. The blood sample collection was performed during three periods: 1) rest, 2) 30min after exercise (speed race of 12km/h for 30min with no rest) and 3) 60min after exercise. Mean values were calculated for cations (sodium and potassium) and anions (chloride and bicarbonate). The resulting data set was analyzed using Gaussian distribution and...

Autores: Machin,A.B.; Nascimento,L.F.; Mantovani,K.; Machin,E.B.
Exposure to air pollution is an important cause of hospital admissions due to respiratory diseases. Nevertheless, few studies use pollutant concentration data estimated by mathematical models. A time-series ecological study was developed, using data from hospitalizations due to respiratory diseases in people over 60 years of age, residents of Cuiabá, Brazil, during 2012, obtained from the Brazilian Ministry of Health. The independent variables were the concentrations of fine particulate matter (PM2.5) and carbon monoxide (CO) estimated by mathematical modeling, minimum temperature, and relative humidity (obtained from the Brazilian Meteorological Agency), and the number of forest fires. The generalized linear regression model of Poisson was used, with lags...

Various protocols are currently used to study marine lipids, but there is a growing interest in working on dry samples that are easier to transport. However, reference protocols are still lacking for dry samples. In order to make recommendations on this use, lipid classes and fatty acids (FA) obtained from six analytical protocols using two different tissue states (dry vs wet) and three extraction methods (automat vs manual potter vs leaving the solvent to work on tissue) were compared. Three dry storage modes of tissue (freezer vs gas nitrogen vs dry room) during one and three months were also compared. These comparisons were made on seven marine species with different lipid profiles, including fishes, crustaceans and mollusks. Lipid classes and FA...

Abstract The effects of gamma radiation (0, 1, 2 and 3 kGy) were used to evaluate the stability and thermal degradation kinetics of anthocyanins, as well as the stability of total phenolic compounds (TPC) and antioxidant activity at different temperatures (4, 25, 35 and 45 °C) during the storage (0, 30, 60, 90 and 120 days) of black rice flour. This flour can be used as ingredient for gluten-free cereal products with higher nutritional value. For this it is necessary to preserve the anthocyanin content during thermal processing and shelf-life periods. At time 0, the dose of 3 kGy provided all of the most available bioactive compounds, raising their antioxidant potential, except for TPC. During the storage at different temperatures up to 120 days, gradual...

Effects of gene therapy on cardiovascular symptoms of lysosomal storage diseases
Provedor de dados: 74
Autores: Poletto,Edina; Pasqualim,Gabriela; Giugliani,Roberto; Matte,Ursula; Baldo,Guilherme.
Abstract Lysosomal storage diseases (LSDs) are inherited conditions caused by impaired lysosomal function and consequent substrate storage, leading to a range of clinical manifestations, including cardiovascular disease. This may lead to significant symptoms and even cardiac failure, which is an important cause of death among patients. Currently available treatments do not completely correct cardiac involvement in the LSDs. Gene therapy has been tested as a therapeutic alternative with promising results for the heart disease. In this review, we present the results of different approaches of gene therapy for LSDs, mainly in animal models, and its effects in the heart, focusing on protocols with cardiac functional analysis.

ABSTRACT The aim was to investigate the effect of glutamine (Gln) on broilers challenged with Salmonella Enteritidis. 240 1-day-old birds were divided into four groups in a completely randomized design, each of which included 6 replicates with 10 birds per replicate. Group I served as the unchallenged, untreated control (CON). All birds in groups II (SCC) - IV were challenged with 2.0 × 104 CFU/mL of S. Enteritidis. Birds in group III and IV were treated with 0.5% (Gln 1) and 1.0% (Gln 2), respectively, of Gln. The results indicated that S. Enteritidis infection led to a decrease in the average body weight at d 7, 14, and 21 (p&lt;0.05). Chickens fed the Gln showed improved average body weights in comparison with the SCC group (p&lt;0.05). At d 4, 7, 14,...

Effects of High Stocking Grazing Density of Diverse Swards on Forage Production, Animal Performance and Soil Organic Matter: A Case Study
Provedor de dados: 21
Autores: Zaralis, Konstantinos; Padel, Susanne.
Mob grazing is regarded as a grazing management practice to increase soil organic matter, pasture productivity and nutrient cycling. There are different perspectives in the literature regarding the definition of mob grazing, but it is generally accepted that mob grazing is characterised by high stocking densities of livestock which are moved frequently from paddock to paddock (e.g.  with the aid of electric fences), trampling forage into the soil as they graze. It has also been recognised that biodiverse pastures have the potential to build up carbon levels in the soil much more effectively than conventional (usually monocultures) or less diverse pastures; in turn all can enhance animal productivity and maintain good herd health.   This paper reviews the...

Effects of hot‐water and steam blanching of sliced potato on polyphenol oxidase activity
Provedor de dados: 21
Autores: Moscetti, Roberto; Raponi, Flavio; Monarca, Danilo; Ferri, Serena; Bedini, Giacomo; Massantini, Riccardo.
The worldwide potato production is considered the fourth-most important food sector due to the increasing use of potatoes as raw materials for high-convenience food. Colour is a crucial quality attribute in fresh-cut potatoes, and enzymatic browning, due to polyphenols oxidase (PPO), is related to unacceptability by consumer. Among additives used to minimize discoloration, sulphites are very common, but affected by health-related hazards and marketing issues. Viable alternatives are thermal treatments, used to inactivate enzymes and improve product shelf-life. In this study, the efficacy of hot-water and steam blanching from 80 to 90°C, used to inactivate PPO in 1-cm potato slices, was evaluated in terms of inactivation kinetic, substrate specificity and...

ABSTRACT It is important to identify the best inspired fraction of oxygen in a variety of situations, including sevoflurane or isoflurane anesthesia, in spontaneously breathing rabbits. For this, 64 rabbits were assigned to eight groups: GI100 (FiO2= 1,0 + isoflurane), GS100 (FiO2= 1,0 + sevoflurane), GI80 (FiO2= 0,8 + isoflurane), GS80 (FiO2= 0,8 + sevoflurane), GI60 (FiO2= 0,6 + isoflurane), GS60 (FiO2= 0,6 + sevoflurane), GI21 (FiO2= 0,21 + isoflurane), GS21 (FiO2= 0,21 + sevoflurane). The induction was performed with (2.5MAC) of the anesthetic. The vaporizer was setted at 1.5 MAC and FiO2 as attributed for each group. After the induction, the concentration was changed to 1 MAC. Measurements of parameters were performed 30 minutes after induction (T0),...

Microalgal biotechnology has gained considerable importance in recent decades. Applications range from simple biomass production for food and animal feed to valuable products for fuel, pharmaceuticals, health, biomolecules and materials relevant to nanotechnology. There are few reports of the exploration of wider microalgae biodiversity in the literature on high value microalgal compounds, however, because it is believed that there is little to be gained in terms of biomass productivity by examining new strains. Still, without diversity, innovation in biotechnology applications is currently limited. Using microalgal diversity is a very promising way to match species and processes for a specific biotechnological application. In this context, three benthic...

ABSTRACT The objective of the present study was to investigate the effect of single nucleotide polymorphism (SNP) of the melanocortin 1 receptor (MC1R) gene on plumage coloration in mule ducks. PCR-high-resolution melting analysis (PCR-HRM) and DNA sequencing were used to identify the SNP variability of the MC1R gene in white common ducks. Three non-synonymous SNP (MC1R gene exon 1, c.52G&gt;A, c.376G&gt;A, and c.409G&gt;A) were identified in white Tsaiya ducks. Mating test (white Tsaiya ducks × white Muscovy drakes) in combination with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed to investigate the effect of non-synonymous SNP of different maternal lines on plumage coloration in mule ducks. Genotyping results...

Photodynamic therapy, by reducing pain and inflammation and promoting the proliferation of healthy cells, can be used to treat recurrent lesions, such as diabetic foot ulcers. Studies using the photosensitizer phthalocyanine, together with the nanostructured copolymeric matrix of Pluronic® and Carbopol® for the treatment of diabetic foot ulcers and leishmaniosis lesions, are showing promising outcomes. Despite their topical or subcutaneous administration, these molecules are absorbed and their systemic effects are unknown. Therefore, we investigated the effect of the subcutaneous administration of the hydroxy-aluminum phthalocyanine hydrogel without illumination on systemic parameters, markers of liver injury, and liver energy metabolism in type 1 diabetic...

The term inflammaging is now widely used to designate the inflammatory process of natural aging. During this process, cytokine balance is altered, presumably due to the loss of homeostasis, thus contributing to a greater predisposition to disease and exacerbation of chronic diseases. The aim of the study was to analyze the relationship between pro-inflammatory markers and age in the natural aging process of healthy individuals. One hundred and ten subjects were divided into 5 groups according to age (22 subjects/group). Interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) were quantified using the ELISA method. High-sensitivity C-reactive protein (hsCRP) was analyzed by turbidimetry according to laboratory procedures. The main findings of this study...

ABSTRACT Although nickel (Ni) is recognized as plant nutrient since the turn of the 21st century, uncertainty remains about its optimum application rates and forms. This paper focuses on Ni application in soils, relating to its effect as a plant micronutrient. Specifically, the effect of Ni on the activity of urease in soybean plants is examined. The effects of applying four Ni rates in two different soil types were tested. A full factorial 2 × 4 blocked design experiment was established under controlled conditions. Ni rates (0, 0.25, 0.5 and1.0 mg of Ni·kg–1 of soil) were applied in two soils with contrasting clay contents. The addition of Ni increased the urease activity in soybean plants but was affected by soil textural differences. The highest urease...

Provedor de dados: 5
Autores: Thomas, Yoann; Flye Sainte Marie, Jonathan; Chabot, Denis; Aguirre-velarde, Arturo; Marques, Gonçalo M; Pecquerie, Laure.
Hypoxia is a decrease in dissolved oxygen that causes physiological disturbances in marine fishes and invertebrates, including reduced mobility, growth rate and reproductive success, altered phenology and increased vulnerability to diseases. Under pressure from global changes such as warming or eutrophication, ocean and coastal ecosystems worldwide are becoming less oxygenated. In order to better understand the consequences of hypoxia on marine systems, there is a need for predicting hypoxia-induced changes from individual organisms to populations. By combining the effect of several stressors on species metabolic performances and life-history traits across their full life-cycle, the Dynamic Energy Budget (DEB) theory offers a suitable framework for...

ABSTRACT In this study, our goal was to clarify the role of proteasomal subunit α-1 (PSMA1) in both the differentiation of preadipocytes and the accumulation of lipids in adipocytes. Preadipocytes from healthy one-day-old calves were collected, isolated, and cultured in vitro. The expression pattern of the PSMA1 gene was explored during the differentiation of bovine preadipocytes firstly. Then, the expression of the PSMA1 gene was inhibited by transfection of a chemically synthesized small interfering RNA (siRNA) before differentiation. After induction of differentiation, the mRNA levels of key regulating genes involved in preadipocyte differentiation and the lipid content of mature adipocytes with and without inhibition of PSMA1 were detected by qRT-PCR...

ABSTRACT: An important drawback in adopting minimum tillage (MT) and no-tillage (NT) techniques is the frequently observed weed shift promoting adapted species and achieving poorer weed control. These changes can be detected best with long-term experiments, and results might differ depending on soil characteristics and the local flora. The objectives of this work were to evaluate the effect of reduced tillage on weed seed distribution in the soil profile and to identify possible consequences on weed diversity on a long-term experiment maintained during 24 years in Seville (Spain) with three tillage systems: NT, MT and conventional tillage (CT) including moldboard plow on a vertisol. For this purpose, soil seedbanks at 0-8 cm and 8-16 cm depths were...

Overaged full-sun cacao plantations and the need for sustainable production systems call for combining rehabilitation of plantations with the establishment of agroforestry. We tested the effect of drastic rehabilitation pruning of old cacao tree stock and the introduction of both high- and low-diversity agroforestry on survival, growth and yield of T. cacao in a commercial plantation in peninsular Malaysia over a period of 5 years. We further determined the incidence of pests and diseases of cacao pods and assessed the performance of the whole system for smallholder farmers, including yields of by-crops. Rehabilitation pruning negatively affected cacao tree development and short-term yield. No more effects of pruning on cacao yield were observed starting...

Docks (Rumex spp.) are a considerable problem in grassland production worldwide. We investigated how different cultural management techniques affected dock populations during grassland renewal: (I) renewal time, (II) companion crop, (III) false seedbed, (IV) taproot cutting (V), plough skimmer and (VI) ploughing depth. Three factorial split-split plot experiments were carried out in Norway in 2007–2008 (three locations), 2008–2009 (one location) and 2009 (one location). After grassland renewal, more dock plants emerged from seeds than from roots. Summer renewal resulted in more dock seed and root plants than spring renewal. Adding a spring barley companion crop to the grassland crop often reduced dock density and biomass. A false seedbed resulted in 71%...

Effects of Sand Addition and Bed Flushing on Gravel Bed Surface Microtopography and Roughness
Provedor de dados: 5
Autores: Bertin, Stephane; Friedrich, Heide.
Gravel riverbeds naturally present a range of sediment size that can span several orders of magnitude. However, fine sediment (i.e., size &lt;2 mm) additions affect sediment transport and are potentially harmful to the river ecology. Limited research has been done to understand the effects of sand addition on gravel bed topography. For this study, we conducted flume experiments testing the effectiveness of topography remote sensing to measure the response of a water-worked gravel bed to varying sand additions and bed flushing. Repeated measurements of the bed topography with through-water photogrammetry show that sand deposits primarily in low-lying areas of the bed, where it is sheltered. Observed changes in bed elevation standard deviation, skewness, and...

ABSTRACT The apparent soil electrical conductivity (ECa) is an attribute commonly used for the characterization of the spatial variability of soil, but its determination by handheld sensors consumes considerable time and labor. The reduction in the number of sampling points allows minimize them but can result in increased uncertainty of interpolated maps. Thus, the goal of this study was to identify the best spacing and number of ECa measurements, to guarantee the quality of maps generated in three vineyards. The ECa values were obtained using a handheld sensor in different sampling grids. The data were submitted to descriptive statistical and geostatistical analyses. The relative deviation and Kappa coefficient of agreement were used to assess the...

Autores: Rittl, Tatiana; Krogstad, Tore; Eikås, Sondre; Saltnes, Torgeir; Sørensen, Gjermund; Glestad, Hans Emil; Løes, Anne-Kristin.
The soil P concentration commonly declines over time by organic management, if the farm does not acquire enough fertilisers or other inputs containing P from outside. An interesting source to supply farms with P is struvite (magnesium‐ammonium phosphate). This mineral easily precipitates when the concentrations of these nutrients is high enough, such as in a toilet separating urine. Struvite  may be produced in a wastewater treatment plant, as a method to reduce the P concentration in the water reaching the recipient. If struvite is allowed as a mineral fertiliser in the general fertiliser regulation of the European Union,which is currently under revision, this mineral may be allowed also in certified organic agriculture. A wastewater treatment plant in...

Autores: Pizzigatti,D.; Raffael,L.A.; Rodrigues,C.A.; Watanabe,M.J.; Alves,A.L.G.; Barbosa,L.; Hussni,C.A.
ABSTRACT The tenectomy of the medial head of the deep digital flexor (TMHDDF) is a minimally studied surgery used in cases of dorsal subluxation of the proximal interphalangeal joint of the hindlimb in horses. The TMHDDF was evaluated in six healthy horses by the degree of lameness, perimeter of the surgical site, the angle of the distal articular joints, and the linear and angular measures of the hoof. Thus, TMHDDF of the right hindlimb was performed and the contralateral limb was used as a control. Both, right and left limbs were evaluated before surgery, as well as at 15, 30, and 60 days after surgery aiming to evaluate the effects of the surgical procedure in healthy limbs. Data were compared by analysis of variance regarding days and limbs. Values...

Effects of the Environment on Developmental Plasticity and Infection Success of Schistosoma Parasites - An Epigenetic Perspective
Provedor de dados: 5
Autores: De Carvalho Augusto, Ronaldo; Duval, David; Grunau, Christoph.
Evidence of how environmental cues affect the phenotypes of, and compatibility between Schistosoma mansoni and their hosts come from studies in environmental parasitology and research on host diet and chemotherapeutic treatment. Schistosomes deal with a multitude of signals from the water environment as well as cues that come from their hosts, particularly in response to molecules that serve to recognize and destroy them, i.e., those molecules that arise from their hosts' immune systems. These interactions shape, not only the parasite's morphology, metabolism and behavior in the short-term, but also their infection success and development into different stage-specific phenotypes later in their life cycle, through the modification of the parasite's...

Effects of the introduction of an omnivorous fish on the biodiversity and functioning of an upland Amazonian lake
Provedor de dados: 36
Autores: NOBRE,Regina L. G.; CALIMAN,Adriano; GUARIENTO,Rafael D.; BOZELLI,Reinaldo L.; CARNEIRO,Luciana S.
ABSTRACT The introduction of nonnative species is one of the main threats to freshwater ecosystems. Although omnivory and intraguild predation are common in those systems, little is known about the effects of introduced omnivorous fish on pelagic and littoral communities. This study tested predictions of food-web theory regarding the effects of omnivorous fish introduction on previously fishless lakes in the Amazonian uplands of Serra dos Carajás, Pará, Brazil. The trophic structure of two similar lakes, one with and the other without the introduced omnivorous fish Astyanax bimaculatus, was compared using a data series of biotic variables collected from both lakes twice a year from 2010 to 2013. Zooplankton was more abundant in the lake with fish, and the...

Organic pig husbandry systems in Europe are diverse – ranging from indoor systems with concrete outside run (IN) to outdoor systems all year round (OUT) and combinations of both on one farm (POUT). As this diversity has rarely been taken into account in research projects on organic pig production, the aim of this study was to assess and compare pig health, welfare and productivity in these three systems. Animal health and welfare were assessed using direct observation and records of 22 animal-based measures, comprising 17 health-, 3 productivity- and 2 behavioural measures. These were collected in pregnant sows, weaners and fattening pigs during direct observations and from records within a cross-sectional study on 74 farms (IN: n=34, POUT: n=28, OUT:...

Effects of upwelling duration and phytoplankton growth regime on dissolved oxygen levels in an idealized Iberian Peninsula upwelling system
Provedor de dados: 5
Autores: Bettencourt, João H.; Rossi, Vincent; Renault, Lionel; Haynes, Peter; Morel, Yves; Garçon, Véronique.
We apply a coupled modelling system composed of a state-of-the-art hydrodynamical model and a low complexity biogeochemical model to an idealized Iberian Peninsula upwelling system to identify the main drivers of dissolved oxygen variability and to study its response to changes in the duration of the upwelling season and in phytoplankton growth regime. We find that the export of oxygenated waters by upwelling front turbulence is a major sink for nearshore dissolved oxygen. In our simulations of summer upwelling, when phytoplankton population is generally dominated by diatoms whose growth is largely enhanced by nutrient input, net primary production and air-sea exchange compensate dissolved oxygen depletion by offshore export over the shelf. A shorter...

ABSTRACT This experiment was conducted to evaluate the effects of dietary protein and net energy (NE) levels on growth performance, nutrient digestibility, nitrogen metabolism, and faecal microbiota of growing-finishing pigs. Eighteen crossed barrows were randomly allocated into one of three dietary treatments: high protein + high NE diet, low protein + high NE diet, and low protein + low NE diet. The whole experiment lasted 90 days and was divided into three phases (phase I: 25-50 kg; phase II: 50-75 kg; phase III: 75-105 kg). All pigs were individually housed in a metabolism cage and subjected to four-day total faeces and urine collection period at the end of each phase. There was no significant difference in growth performance, nutrient digestibility,...

Autores: Leiber, Florian; Willems, Helen; Werne, Steffen; Ammer, Stefanie; Kreuzer, Michael.
The known influence of forage composition on fatty acid (FA) profiles in ruminants’ meat and milk may be different for other organs. Therefore, in the present study FA profiles of phospholipids in lung tissue, heart muscle and brain (medulla oblongata) were examined in growing Engadine and Valaisian Blacknose sheep grazing 4 pastures of different botanical composition, whereof three were extensively managed natural mountain swards. An intensively managed lowland pasture represented the control. On each pasture type, 6–7 lambs of each breed (54 in total) grazed for 9 weeks and were subsequently slaughtered. Tissue samples were taken at slaughter, homogenized and analyzed for FA profiles after phospholipid extraction. Response to the diets was  tissue...

Autores: Yin,L; Ran,J; Lian,T; Yang,C; Li,S; Liu,Y.
ABSTRACT The objective of this study was to analyse the impact of dietary vitamin E supplementation on laying performance, serum reproductive hormones concentration and gene expression in ovary and follicles of anti-season breeding goose. A total of 210 anti-season breeding geese were divided into seven treatments with six replications. Each group was supplied with diets containing different vitamin E (DL-α-tocopherol acetate) contents (0, 10, 20, 40, 80, 160, 320mg/kg). We observed that the egg production and laying rate improved significantly at doses of 10 and 80 mg/kg, while the highest egg weight appeared in the 320 mg/kg group. Meantime, 80 mg/kg of vitamin E supplementation significantly improved the concentration of follicle-stimulating hormone...

Provedor de dados: 1
Autores: Martinez, Mauro; Arata, Agustín Francisco; Lázaro, Laura; Stenglein, Sebastian Alberto; Dinolfo, María Inés.
Waterlogging stress is one of the abiotic factors which causes damage to crops affecting yield components and grain quality of wheat and barley. On the other hand, Fusarium poae is one of the most common Fusarium species isolated from wheat and barley. The aim of this study was to evaluate the effects of waterlogging and F. poae on disease parameters, yield components and grain quality of durum and bread wheat and barley. The experiment was carried out using pots under greenhouse conditions. Four treatments were applied: control/control (W0F0), control/F. poae (W0F1), waterlogging/control (W1F0) and waterlogging/F. poae (W1F1). The results showed that incidence, severity and FHB index of F. poae were higher in W0F1 compared to W1F1 suggesting that...

Provedor de dados: 21
Autores: Lambertz, Christian; Leopold, Jochen; Damme, Klaus; Vogt-Kaute, Werner; Ammer, Stefanie; Leiber, Florian.
Hintergrund: Deckung des Bedarfes an Riboflavin (Vitamin B2) mit ausschließlich ökologisch erzeugten Futterkomponenten in der Aufzucht von Mastpoulets kritisch, da native Gehalte in Getreide und Leguminosen zu gering sind. Am Markt ist aktuell kein ohne Gentechnik hergestelltes Riboflavin verfügbar, daher sind Alternativen in Form von Riboflavin- haltigen Futtermitteln zur Aufwertung von Öko-Futtermischungen notwendig.

Autores: Lehner, Daniel; Starz, Walter; Pfister, Rupert; Rohrer, Hannes.
Körnerleguminosen spielen in der ökologischen Landwirtschaft eine wichtige Rolle, einerseits als hochwertige Proteinquelle, andererseits als zentrales Element der Fruchtfolge. Die Auswirkung der Düngung mit Rohphosphat und elementarem Schwefel auf die vier bedeutenden Körnerleguminosen Ackerbohne, Körnererbse, Lupine und Sojabohne wurde untersucht. Diese beiden wichtigen Nährstoffe können bei gemeinsamer Ausbringung sich in der Wirkung gegenseitig positiv beeinflussen. Das erste Versuchsjahr brachte keine signifikanten Unterschiede in den Ergebnissen, aber eine positive Wirkung des Elementarschwefels.

In den letzten Jahrzehnten hat ein dramatischer Artenrückgang in landwirtschaftlichen Regionen stattgefunden und eine Trendwende ist nicht in Sicht. Trotz vieler Belege für die positiven Auswirkungen der ökologischen Landbewirtschaftung auf die Biodiversität gibt es keine neueren, quantitativen Literaturstudien im Vergleich zu konventioneller Bewirtschaftung, in denen statistische Parameter Berücksichtigung fanden. In diesem systematischen Review wurden die Effekte beider Bewirtschaftungssysteme auf  ausgewählte Artengruppen verglichen. Wir beziehen uns auf 64 Studien, in denen die mittlere Artenzahl und Abundanz untersucht wurden. Die Auswertung ergab deutlich positive Ergebnisse der ökologischen Bewirtschaftung auf die Flora (85-100 %) und Fauna...

Provedor de dados: 21
Autores: Starz, Walter; Kiendler, Stefanie; Steinwidder, Andreas; Lehner, Daniel; Pfister, Rupert; Rohrer, Hannes.
Schwefel ist ein wichtiger Pflanzennährstoff und die Immissionen aus der Atmosphäre gingen seit 1980 stark zurück. Unter diesen Rahmenbedingungen wurde der Einsatz eines elementaren Schwefeldüngers ("Sulfogüll plus" von BvG) auf einer 4-schnittigen Dauerwiese getestet. Vier Schwefeldüngungsstufen von 0 (S0), 30 (S30), 60 (S60) und 90 (S90) kg S/ha stellten die Varianten dar. Variante S60 und S90 erreichten die signifikant höchste TM- (S60 10.779 und S90 11.073 kg/ha) XP- (S60 1.749 und S90 1798 kg/ha) und Energie-Erträge (S60 64.008 und S90 65.370 MJ/ha) im Vergleich zur Variante S0 (TM: 9.947 kg/ha, XP: 1.569 kg/ha, Energie: 58.434 MJ NEL/ha). Ein Ziel der Bio-Landwirtschaft ist, möglichst viel Eiweiß aus dem Grünland zu gewinnen. In diesem Fall dürfte...
