Effect of leaf decomposition stage and water temperature on fragmentation activity of a shredder invertebrate species in lotic ecosystems
Provedor de dados: 76
Autores: Navarro,Fernanda K. S. P.; Gonçalves Júnior,José F.
ABSTRACT The attractiveness of a given leaf detritus to invertebrates depends on the chemical composition, physical structure, stage of microbial colonization and decomposition level. In addition to the leaf detritus quality, water temperature also affects organic matter cycling in aquatic environments. In this context, the objectives of this study were: i) to increase knowledge about the role of invertebrate shredders on fragmenting senescent, conditioned senescent and green leaves of Richeria grandis Vahl. (Phyllanthaceae) under gradual temperature rise and check leaf mass loss; ii) to verify the preference of Phylloicus sp. (Trichoptera) for leaves for larval case production. The experiment I consisted of three treatments with different water...

IMPACTO das cinzas de queimadas no solo, na água e na vida humana: programa 28: Centro-Oeste/Sudeste.
Provedor de dados: 14
Esta semana, o Prosa Rural fala sobre o impacto das cinzas de queimadas no solo, na água e na vida das pessoas. Cientistas concluíram que a presença das cinzas das queimadas altera a composição química do solo. E quando ocorre o escoamento superficial após uma chuva, substâncias presentes nas cinzas atingem as águas subterrâneas e superficiais, contaminando-as. Mesmo diante desses problemas, o fogo continua sendo utilizado na agricultura, trazendo sérias consequências. Convidamos o pesquisador Eduardo Cyrino pra falar sobre o assunto.

Autores: Cardinal, Mireille; Cornet, Josiane; Donnay-moreno, Claire; Gouygou, Jean-paul; Berge, Jean-pascal; Rocha, E.; Soares, S.; Escorcio, C.; Borges, P.; Valente, L. M. P.
This study describes the variability of important quality traits in gilthead sea bream produced under intensive conditions in Southern Europe and purchased in a French market (Nantes). Chemical, sensory and histological characteristics were performed on 18 samples delivered over a year. All fish presented far lower dioxin and DL-PCBs or heavy metals concentrations than the maximum limit level set by EC Regulation, being totally safe for human consumption. Fat content and nutritional values reflected by n-3 and n-6 polyunsaturated fatty acids (PUFA) levels were parameters with high variability according to the season or the fish farm. Values of n-3 PUFA ranged from 0.9% to 8.6% and those of n-6 PUFA from 9.3% to 16.6%, corresponding to a respective...

Daily variations of the saccular endolymph and plasma compositions in the turbot Psetta maxima: relationship with the diurnal rhythm in otolith formation
Provedor de dados: 5
Autores: Edeyer, Anaick; De Pontual, Helene; Payan, P; Troadec, Herve; Severe, Armelle; Mayer-gostan, N.
We studied the circadian variations of the ionic composition ([Na+], [K+], [Cl-]), total CO2 ([tot CO2]), and protein concentration ([protein]) in the plasma and endolymph in the distal and proximal sides of the sacculus in the turbot Psetta maxima. Daily variations in total plasma calcium ([tot Ga]) were also recorded. Significant diurnal fluctuations occurred in most parameters and the spatial heterogeneity of the endolymph composition was maintained throughout a 24 h period. The main parameters implicated in otolith calcification, endolymph [tot CO2] and endolymph [protein], fluctuated diurnally, [tot CO2] was highest and [protein] lowest at night; the relative concentrations were reversed during the day. The inverse, alternating relationship of maximal...

Water-soluble sulfated polysaccharides isolated from two red algae Sphaerococcus coronopifolius (Gigartinales, Sphaerococcaceae) and Boergeseniella thuyoides (Ceramiales, Rhodomelaceae) collected on the coast of Morocco inhibited in vitro replication of the Human Immunodeficiency Virus (HIV) at 12.5 mu g/mL. In addition, polysaccharides were capable of inhibiting the in vitro replication of Herpes simplex virus type 1 (HSV-1) on Vero cells values of EC(50) of 4.1 and 17.2 mu g/mL, respectively. The adsorption step of HSV-1 to the host cell seems to be the specific target for polysaccharide action. While for HIV-1, these results suggest a direct inhibitory effect on HIV-1 replication by controlling the appearance of the new generations of virus and...

The potential of near infrared spectroscopy (NIRS) to measure the chemical composition of aquaculture solid waste
Provedor de dados: 5
Autores: Lopes Galasso, Helena; Callier, Myriam; Bastianelli, Denis; Blancheton, Jean-paul; Aliaume, Catherine.
In aquaculture, it is extremely important to determine the composition of fish farm waste to evaluate its potential impacts and to improve its reuse. Near-infra red spectroscopy (NIRS), an alternative to standard chemical analytical techniques, is a quick non-invasive method to assess physical and chemical composition, reducing the cost of routine analysis. We developed NIRS calibration models for organic matter (OM), total organic carbon (TOC), total organic nitrogen (TON), the carbon/nitrogen ratio (C/N), total phosphorus (TP) and the lipid content of marine fish particulate waste. To obtain a wide range of compositions of fish waste, decomposition time, feed loss, and inter-specific variations were taken into account. The NIRS calibration models were...

Hydrothermal Vents: Oases at Depth
Provedor de dados: 5
Autores: Sarrazin, Jozee; Desbruyeres, Daniel.
The synthesis of organic molecules in hydrothermal fluids raises the question of what role hydrothermal vents may have played in the emergence of life on Earth. These deep‐sea ecosystems were most likely protected from extreme conditions at the surface (meteor showers and ultraviolet radiation). Since the middle of the 19th century, scientists have questioned the position of deep‐sea animals in the evolution of marine fauna, in the hope to discover the missing link, i.e. the species or group that may have survived mass extinctions in this protected and stable environment. This chapter discusses the geology and geochemistry of hydrothermal systems, microbial chemosynthesis, symbioses and trophic chains, and fauna at different spatial scales. Fauna...

The concentration of chlorophyll a in large out-door continuous cul­ture was analysed in spring 1977 and 1978, and autumn - winter 1977-1978. The growth of marine phytoplankton in springsl977 is analysed with more details and shows three phases : - first, the diatoms (especially Skeletonema costatum) grow rapidely (27/4 to 3/5). The growth rate estimated by the chlorophyll measurements is 1.36 day“1. - then (3/5 to.13/5) the concentration of chlorophyll remains more or less constant (23.611.2 mg/m3) as well as the concentration of particulate organic matter. - at the end of the experiment (13/5 to 20/5) the concentration of chlo­rophyll falls as soon as Skeletonema costatum decrease in number.The declin of the phytoplankton biomass is followed by an...

Two different biomasses (100 g multiplied by m super(-2) and 1 kg multiplied by m super(-2)) of oysters were put in identical sea-water ponds, thus leading to different trophic conditions, corresponding to rearing techniques. Changes in growth, biochemical composition and sexual maturation were recorded for two age groups. The first one included 9 month-old oysters and the second one 21 month-old oysters, at the beginning of the experiment. For both age groups, significant differences were observed in growth and biochemical composition. Lipids were accumulated faster for the lower biomass. However, the only difference concerning glycogen was observed on the older oysters. They showed a peak at the lowest biomass and a decrease at the larger biomass. Sexual...

Three species of corals Stylophora pistillata, Lobophyllia corymbosa and Echinopora gemmacea were collected from Sharm Obhur to study their chemical composition. This information was important in the investigation of their metabolic pathways and their mode of feeding. The concentrations of amino acids in these species were 9.37, 21.35 and 3.09 mg.g(-1) dry weight of coral respectively. Plant pigments were highest in E. gemmacea followed by S. pistillata and then by L. corymbosa. Lipid concentrations in S. pistillata, L. corymbosa and E. gemmacea were 1.90, 8.58 and 1.32 mg.g(-1) of total coral respectively. The fatty acid methyl esters were analyzed in these species and the most abundant saturated acids were 16:0 and 18:0, while unsaturated acids included...

Autores: De Francesco, M; Parisi, G; Perez Sanchez, J; Gomez Requeni, P; Medale, Francoise; Kaushik, Sadasivam; Mecatti, M; Poli, B.
Juvenile gilthead sea bream (initial body weight ca. 100 g) were reared in an indoor flow through marine water system for 1 year. Fish were fed two isoenergetic [19.2 kJ g&amp;#8722;1 dry matter (DM)] and isoproteic (426 g kg&amp;#8722;1 DM) diets either based on fish meal (diet FM) or on a mixture of plant protein sources (diet PP), replacing 75% of fish meal protein. The growth trial was conducted in duplicate, two tanks for each dietary treatment. Growth performance and feed utilization were registered. Fillet quality parameters were evaluated and sensory analyses on cooked fillet were performed. Both groups had similar weight gain and specific growth rates. Feed intake was higher in sea bream fed diet FM (0.48 versus 0.44), while feed efficiency and...

La boutargue est constituée par les ovaires salés et séchés des mulets à grosse tête (Mugil cephalus) et de la courbine (Argyrosomus regius) représente une ressource importante pour la région de Nouakchott  et pour la Mauritanie. Pour déterminer la valeur énergétique dans les boutargues, nous avons effectué des dosages des protéines, des glucides, des lipides et des études analytiques des acides gras et des lipides. Les analyses ont révélé que la boutargue contient, par rapport aux autres éléments d’énergie, très peu de glucide : 3,29% dans la boutargue du mulet et 1,95% dans celle de la courbine. Alors que les teneurs en protéines et lipides sont importantes et sont respectivement de 44,44% et 31,68% dans la boutargue du mulet et de 55,11% et 15,86% dans...

During april 1995 hydrochemical research in a vertical column on the east side of the Galápagos Islands (Cruise T95/04/01) onboard of the INP R/V Tohallí indicated that concentrations of ammonium, nitrate, phosphate and chlorophyll-a were found stratified from the surface to deeper layers, on the other hand the maximum levels of nitrite and silicate were detected 70 m below the thermocline. The apparent oxygen use (AOU) varied from 1 to over 3 below the thermocline, this would indicate an oxidating environment due to the high levels of nitrate, phosphate, silicate and low concentrations of dissolved Oxygen (ca. 90-134[µM]) and ammonium (&lt;0,1[µM]). According to the high salinity average (35,0 ups), nutritive elements (nitrate 15,6 [µM], silicate 13,1...

Autores: Solórzano, L.; Suéscum, R.T. de.
La concentración de nutrientes en las aguas del Pacífico ecuatoriano durante el período pre-invernal de septiembre y diciembre de 1990 estuvo influenciada, principalmente, por el transporte estacional de aguas oceánicas de diferentes orígenes. La migración de los organismos acuáticos, los procesos biológicos de utilización y mineralización, la sedimentación de las partículas orgánicas a través de la columna de agua, y el drenaje continental, podrían haber influenciado, en menor proporción, las propiedades químicas del área. Durante el crucero llevado a cabo en los meses de septiembre y octubre de 1990, las aguas peruanas de mayor densidad y ricas en nutrientes fueron fácilmente observables a lo ancho del transecto del meridiano 82ºW.

ABSTRACT  The present research aimed to determine the fatty acid profile in the seed oil of cagaita fruits cultivated in Goiânia, state of Goiás, in 2013 and 2014 harvests. The study was carried out with fruits produced by cagaita trees cultivated in the field of the School of Agronomy, Federal University of Goiás (EA/UFG), Goiânia, GO, where, in 1998, 440 cagaita seedlings from different municipalities in Goiás were planted. Fruits were collected from plants with 16 years of age in full production stage. Cagaita seeds show in their fatty acid profile mostly linoleic acid, oleic acid and palmitic acid. There was no variation in fatty acids content present in seeds between years 2013 and 2014, assuming that there are no external influences such as weather,...

Caatinga is the most important biome for the livestock in the Brazilian semi-arid region. This review paper aimed to present information on different forage aspects of caatinga vegetation for ruminant feeding. Caatinga vegetation is formed mainly by shrubs and small trees, usually presenting thorns, deciduous leaves, and leaf abscission occurring frequently at the onset of the dry season. Additional components of the botanical composition in this biome includes the families cactaceae, bromeliaceae, and a herbaceous component formed by grasses, legumes, and forbs, often presenting annual cycle. Quantitative information of caatinga vegetation is scarce in the literature, mainly for the herbaceous stratum. Methodological aspects such as lack of...

ABSTRACT The aim of this work was to propose a mathematical model to determine the best combination of the by-products of coffee processing in the production of silage. To this end, 13 treatments were evaluated, resulting from the combination of wet coffee husks (WCH) and dried coffee husks (DCH), both with and without the use of molasses (M) and with or without the use of the inoculant Lactobacillus plantarum (I). From these components, various mixtures were proposed and evaluated, using the technique of simultaneous optimisation of multiple response variables. Silages with the best characteristics were obtained from the use of 76.40% WCH, 18.77% DCH, 4.83% of M and 0.0001% I.

Acylated Steryl Glucosides (ASGs) are unsaponified matters that are ubiquitously distributed in edible plant sources, for example barley, maize and brown rice. ASGs in pre-germinated brown rice have reported to improve insulin activity and blood glucose control mechanisms in the diabetic condition through the activation of insulin like growth factor 1 (IGF-1) and increasing of IGF-1 production. Recently, the medical studies confirm that dietary intake of brown and pre-germinated brown rice is useful for alleviating symptoms of both diabetes and pre-diabetes. To improve the functional dietary intake of Thai rice, identification of ASGs in seven varieties, namely: Khao Dawk Mali 105, PTT1, RD31, Sang Yod, RD6, Niaw Dam Chum Pae and Niaw Dam Maw, brown and...

Potential use of Siparuna guianensis essential oil for the control of Moniliophthora roreri in cacao
Provedor de dados: 109
Autores: Ramos-Calderón,Pablo Fernando; Rodríguez Peréz,Wilson; Castrillón Rivera,Beatriz; Ramos Rodríguez,Fredy; Suárez,Juan Carlos.
Abstract Cacao (Theobroma cacao L.) is a crop of globally importance on whose production around 20 million people depend directly. The crop is threatened due to the incidence of diseases caused by phytopathogenic fungi such as Moniliophthora roreri, causing losses of more than 80 % of the annual production. For this reason, in this study, a natural product such as the essential oil (EO) obtained from Siparuna guianensis was evaluated as a control alternative. The chemical composition of the EO, as well as the antifungal effect in vitro and in vivo on M. roreri, the causal agent of moniliasis frosty pod rot, were determined in the cacao pods located in a commercial plantation in southern Huila, Colombia. 28 compounds were detected, predominating:...

Aniba canelilla (H.B.K.) Mez. is a tree species from Amazon that produces essential oil. The oil extraction from its leaves and stems can be an alternative way to avoid the tree cutting for production of essential oil. The aim of this study was to analyse factors that may influence the essential oil production and the biomass of resprouts after pruning the leaves and stems of A. canelilla trees. The tree crowns were pruned in the wet season and after nine months the leaves and stems of the remaining crown and the resprouts were collected, in the dry season. The results showed that the essential oil yield and chemical composition differed among the stems, leaves and resprouts. The stems' essential oil production differed between the seasons and had a higher...

ABSTRACT It is necessary to determine the sorption isotherms of seeds to develop adequate systems of storage and drying. The chemical composition of a product affects the sorption process; products with a high oil content adsorb a lower amount of moisture from the environment than products with a high carbohydrate content. Given the importance of the hygroscopicity of different agricultural products, this work aimed to determine, model and evaluate the difference between desorption isotherms of ryegrass and flax seeds grown at different temperature and relative humidity conditions.

The main ways by which extra-virgin olive oil is consumed include direct application on salads or as an ingredient in sauces, but it is also been used by some for cooking, including frying and baking. However, it has been reported that under heat stress, some nonglyceridic components of olive oil are degraded. So, the effect of heating (at 50, 100, 150, and 200 °C for 2 h) on the volatile composition and sensory aspects of extra-virgin olive oil were evaluated. Heating altered the volatile composition of extra-virgin olive oil, mainly at higher temperatures (above 150 °C). The main modifications were related to the formation of large amounts of oxidized compounds, particularly large chain aldehydes. Sensory aspects were also altered when the oil was heated...
