Rethinking Partnerships with the Aim of Producing Knowledge with Practical Relevance: a Case Study in the Field of Ecological Restoration
Provedor de dados: 7
Researchers in conservation biology and restoration ecology often work in partnership with local actors to increase the practical relevance of the knowledge they produce. Although an academic mode of knowledge production is essential in research for a better understanding of biological systems, it often fails to produce frameworks and methodologies having practical relevance that can be used in conservation and restoration programs.  The involvement of researchers in collective plans of action is supposed to contribute to the production of a more contextualized  form of knowledge. In this paper, we report our experience of partnership research in an ecological restoration project. We show that changing our mode of knowledge production to one that produces...

Autores: Ragonha,Flávio Henrique; Pinha,Gisele Daiane; Petsch,Danielle Katharine; Mansur,Maria Cristina Dreher; Takeda,Alice Michiyo.
The Ilha Grande National Park, Paraná, Brazil, is located in the Upper Paraná River and has characteristics typical of a floodplains. This protected area includes lagoons connected and disconnected to the Paraná River, although the latter also connect during periods of high water level, thus composing a heterogeneous group of lacustrine environments. The enormous potential the flora and fauna diversities are still little known to the region, as can be seen through benthic invertebrates, inclunding bivalves mollusks. The granulometric composition of these floodplain lagoons was formed mainly by mud and very fine sand. Furthermore, organic matter composition was predominantly of fine particulate. The other abiotic factors differed from lagoons located within...

A domesticação de plantas nativas do Pantanal.
Provedor de dados: 14
Autores: JORGE, M. H. A.
Os interesses do homem em domesticar certos vegetais que fariam parte do seu dia-a-dia, sejam em rituais, sessões de cura, ou até mesmo como parte da sua dieta, estão registrados desde milhares de anos. Estas plantas passaram então por um processo conhecido como seleção, e durante vários anos, foram cultivadas e melhoradas para atender os interesses do homem, no caso de grãos tamanho e número. Atualmente, o homem ainda utiliza a domesticação para muitas espécies que possuem potencial econômico de exploração, seja medicinal, alimentício, verterinário, entre outros. Técnicas mais modernas impulsionaram esse processo de seleção, agilizando assim a condução e obtenção de resultados. Considerando que o Pantanal possui imensa diversidade de plantas que na sua...

The Value of Backyard Biodiversity in New Zealand
Provedor de dados: 31
Autores: Parminter,   Terry G.; Kaval,   Pamela; Yao,   Richard T.; Scrimgeour,   Frank G.
New Zealand's biodiversity consists of over 80,000 types of native plants, animals and fungi, a considerable number of which are indigenous and located on private property. To preserve and enhance native biodiversity and discourage activities that may deplete it, economic values can be calculated which can, in turn, guide the use of policy tools, such as incentives, that can be used. This can support behavioural changes by encouraging individual self-interest to coincide with social interest. In this project, we used the contingent valuation, choice modelling and well-being approaches to estimate native biodiversity values for Wellington residents. In this paper, we present a summary of our initial results.

Provedor de dados: 91
Autores: Coneglian,Ademilson; Ribeiro,Pedro H. P.; Melo,Bruno S.; Pereira,Rennan F.; Dorneles Junior,Joáz.
ABSTRACT High prices and the scarcity of hardwoods require the use of alternative wood sources, such as the Guapuruvu (Schizolobium parahybae), an arboreal species native to the Atlantic Forest, which has fast growth and high market potential. However, there is no information on its cultivation in the Brazilian Cerrado. Thus, this study aimed to analyze the contribution of mineral fertilization and liming in a Cerrado soil on the initial growth of Schizolobium parahybae. The experiment was set in a randomized block design, with 4 treatments (Cerrado soil; soil + liming; soil + fertilizer; and soil + fertilizer + liming) and 15 replicates. The following variables were analyzed: plant height, stem diameter, number of leaves, total, shoot, leaf, root and stem...

Provedor de dados: 91
Autores: Aquino,Simone T. M. de; Santos,Reila F. dos; Batista,Karine D.
ABSTRACT ‘Cedro doce’ [Pochota fendleri (Seem) Alverson &amp; Duarte] is a native forest species in Amazon with great ecological and economic importance. Understanding nutritional requirements of the species allows cultivating Pochota fendleri with more efficient fertilization practices since its initial growth, as a seedling. Thus, this research aimed to evaluate the symptoms of nutritional deficiency of young ‘cedro doce’ plants. The experiment was carried out from September to December 2016, under greenhouse conditions, at Embrapa Roraima, in Boa Vista, RR, Brazil. The experiment was a randomized complete block design with seven treatments [complete solution and individual omission of the macronutrients (N, -P, -K, -Ca, -Mg, -S)] and three replications....

Genetic polymorphism among natural populations of Anacardium humile A. ST-HIL
Provedor de dados: 94
Autores: Santos,Silvia Correa; Carvalho,Raquel dos Santos; Davide,Livia Maria Chamma.
Abstract  The genus Anacardium presents nine species, of these, three have sub-bush size, common in the Cerrado of the Center-West of Brazil. The objective of this work was to evaluate the genetic variability of the species, collected in eleven provenances, using RAPD markers. Genomic DNA from 122 accessions was extracted and amplified with 25 decamer primers. The results indicated polymorphism, ranging from 77.71% to 96.18%. The distribution of genetic diversity among and within populations shows that 27.14% of the variability is found between populations and 37.44% within the populations, suggesting the existence of genetic variability that may be related to the reproductive strategies adopted by the species throughout its evolution. The index of...

Alterations in the lipid and soluble sugar content of melanoxylon brauna seeds during natural and accelerated ageing
Provedor de dados: 95
Autores: Corte,Viviana Borges; Borges,Eduardo Euclydes de Lima e; Gonçalves,José Francisco de Carvalho; Silva,Mirian Sousa.
The decay of seeds is irreversible and at best can only be delayed by applying techniques that reduce the velocity of the metabolic reactions involved. There is little information on the biochemistry of tropical forest tree seeds related to their storability. It was investigated the influence of the composition of lipids and soluble sugars of two storage compartments, the cotyledons and the embryonic axis, of Melanoxylon brauna Schot. (Leguminosae- Caesalpinioideae), a hardwood known as black brauna, seeds stored at 20 ºC for 0, 3, 6, 9 and 12 months (natural ageing) and for 0, 24, 48, 72 and 96 hours at 40 ºC (accelerated ageing). The levels of fatty acids and monosaccharides varied differentially in each of the embryo storage compartments. Changes in...

ABSTRACT Ferruginous Rocky Outcrops have high levels of species richness and endemism, but have been threatened by several anthropic actions, especially mining. Eragrostis polytricha, a common grass species in the vegetation of these outcrops, has shown promising features for use in the recovery of mining areas. However, in order to fully understand the species’ potential for such use, its requirements for germination, seed dormancy break and seedling development must be determined. Thus, we aimed to: (1) assess the temperature conditions needed for seeds of E. polytricha to germinate; (2) evaluate the effects of KNO₃ in breaking seed dormancy; and (3) analyze the germination efficiency of seeds that are still in spikelets. The experiment included seven...

Abstract Supplying food to growing human populations without depleting natural resources is a challenge for modern human societies. Considering this, the present study has addressed the use of native arboreal species as sources of food for rural populations in the Brazilian Atlantic Forest. The aim was to reveal species composition of edible plants, as well as to evaluate the practices used to manage and conserve them. Ethnobotanical indices show the importance of many native trees as local sources of fruits while highlighting the preponderance of the Myrtaceae family. Conservation analysis allowed to identify Campomanesia hirsuta Gardner and Plinia edulis (Vell.) Sobral as being of high Biological Value and Conservation Priority. In spite of that, the...

The Brazilian Cerrado is the richest savanna in the world. It is also one of the biomes more threatened in the country and a hotspot for conservation priorities. The main causes of deforestation in Cerrado are agricultural practices, livestock and charcoal production. Although charcoal has a minor impact, its consumption represents the deforestation of 16.000 Km² of the Cerrado. To contribute for the biomes's conservation it is very important to improve forestry supervision. Thus, in this work we present the macroscopic characterization of charcoal from 25 Cerrado's species. We simulate the real conditions of forest controllers by using the magnifications of 10x, 25x and 65x. Likewise, the charcoals micrographs are all of transverse sections due to the...

Revegetación de áreas degradadas con especies nativas
Provedor de dados: 51
Autores: Dalmasso,Antonio Daniel.
El área de trabajo se localiza al sur de Malargue-Mendoza; es un clima árido, con una precipitación media anual de 134 mm y una temperatra media anual de 13,3°C. Se evalúan los resultados de la revegetación con especies nativas en áreas degradadas por la actividad petrolera propendiendo que los ecosistemas alterados alcancen una mayor estabilidad, en lo posible similar a la situación previa al impacto. Se realizó un inventario geomorfológico y de vegetación estableciéndose hipótesis dinámicas de vegetación. A través del enfoque geosinfitosociológico, y en función de la dinámica vegetal, se seleccionaron un total de 10 especies que fueron reproducidas en vivero y establecidas en tres plataformas petroleras del área, tanto en otoño como en primavera. El...

L. Reyes-Garcia, Y. Cuevas, C. Ballesteros, T. Curkovic, C. Löfstedt, and J. Bergmann. 2014. A 4-component sex pheromone of the Chilean fruit leaf roller Proeulia auraria (Lepidoptera: Tortricidae). Cien. Inv. Agr. 41(2):187-196. The Chilean fruit leaf roller Proeulia auraria is a pest of economically important fruit species. Two compounds attractive to males have been identified as (E)-11-tetradecenyl acetate (E11-14:OAc) and (E)-11-tetradecenol (E11-14:OH) and are currently being used in Chile to monitor this species. Preliminary experiments carried out by our group suggested that the 2-compound mixture might not be optimal for the attraction of males, which prompted us to reinvestigate the sex pheromone of P. auraria in the present study. The pheromone...

Vitamin C and total phenols quantification in calli of native passion fruit induced by combinations of Picloram and Kinetin
Provedor de dados: 65
Autores: Artioli-Coelho,Fabiane Aparecida; Paiva,Renato; Silva,Luciano Coutinho; Barbosa,Sandro; Beijo,Luiz Alberto.
Brazil is one of the center of origin of passion fruit and has an important natural variability of the genus Passiflora. Several wild species of this genus are resistant to some pests and diseases and many are considered as medicinal. The aim of this research was to induce callus from in vitro Passiflora gibertiileaf explants for quantification of vitamin C and total phenols. Once the appropriate auxin/cytokine balance promotes callus formation and may optimize the production of secondary compounds and vitamins, calli were induced using a half-strength MS medium with a combination of the auxin Picloran (PIC) and the cytokine Kinetin (KIN). The vitamin C and total phenols were quantified by colorimetric methods from calli after different culture periods....
