1. Actual status of fishing reserves of the Yesil River
ABSTRACT In this article, the study and prediction of the state of fish resources in the Yesil River was carried out to determine the boundary reference points of the reserve and management decisions in case they are exceeded, to ensure sustainable fisheries and preserve biological diversity. Ichthyological studies, retrospective analyses and rankings of the

2. Advantages of recovery from pre-slaughter stress in tambaqui Colossoma macropomum (Cuvier 1816) agroindustry in the Amazon
Abstract Tambaqui is the main fish species farmed in the Amazon. It is produced on industrial scale, slaughtered in the field, primarily by post-harvest asphyxia. This procedure, however, is stressful because it depletes energy reserves that should be used in postmortem metabolism, which may compromise fish meat freshness and quality. The present study compa

3. Mapeamento de unidades experimentais com GPS: caso de estudo da Embrapa Cerrados.
ABSTRACT: The major objective of this work was to map the research units and the infrastructure available in the Embrapa Cerrados experimental farm in Planaltina, Federal District. More than 190 identities were observed and mapped through the use of GPS portable receiver with an accuracy of about five meters. The UTM coordinates obtained by the GPS were stor

4. Caracterização florística e potencial de uso das espécies vasculares ocorrentes nas fazendas Trijunção, BA.
ABSTRACT: Proper management of natural areas requires phisical (soil, climate and topography) and biological (fauna, flora and microorganisms) characterization. Such information is extremaly useful for management plans of conservation unit such as National Parks, Extractive Reserves of Natural Resources Reserve (RPPN). This study aimed characterize floristic

5. Nitrogen fixation by groundnut and velvet bean and residual benefit to a subsequent maize crop.
Chemical fertilisers are rarely avaiable to poor farmers, for whom the nitrogen (N) is often the most limiting element for cereal grain production. The objective of this study was to quantify the contribution of biological nitrogen fixation (BNF) to groundnut (Arachis hypogaea) and velvet bean (Mucuna pruriens) crops using the 15N natural abundance (d15N) te

7. Child malnutrition in the municipal district of Jordão, Acre State, Brazilian Amazonia / Desnutrição infantil em Jordão, Estado do Acre, Amazônia Ocidental Brasileira
Despite the improvements in child nutrition in developing countries over recent decades, child malnutrition remains a serious public health issue in Brazil, particularly within Amazonia. Nutritional surveys on Amazonian populations are scarce and generally involve indigenous populations settled in reserves. Aim - To ascertain the prevalence and factors assoc

8. Integração de dados ambientais e da avaliação ecológica rápida para o zoneamento da reserva natural Serra do Tombador (Goiás) e diagnóstico do seu entorno
The Private Reserves of the Natural Heritage (Reservas Particulares do Patrimônio Natural) (RPPN) belongs to the Brazilian System of Conservation Units, and they have a cornerstone role for nature conservation given that they allows private land owners, on their own initiative, to contribute in the establishment of new protected areas on their lands. The RP

9. Ictioplâncton na Unidade de Conservação Reserva Biológica Marinha do Arvoredo e Áreas Costeiras Adjacentes, Santa Catarina, Brasil
Arvoredo Island (Santa Catarina, Brazil) and its surrounding area were defined as Conservation Unit (CU) in the category of Biological Reserve in 1990. Biological Reserves are protected areas that have complete and permanent preservation of local flora and fauna, thus contributing to the increase of abundance and diversity of species. This research aimed at

10. Terrestrial arthropods as biological indicators of anthropogenic disturbance / Artropodes como indicadores biologicos de pertubação antropica
In this study, the responses of terrestrial arthropods to different types of anthropogenic disturbance were examined, aiming to select and test ecological indicators. Ten groups of terrestrial arthropods were selected and sampled in an Atlantic Forest reserve with two sites with contrasting histories of disturbance, one with history of selective logging (pre

11. A nutrition mathematical model to account for dietary supply and requirements of energy and nutrients for domesticated small ruminants: the development and evaluation of the Small Ruminant Nutrition System
A mechanistic model that predicts nutrient requirements and biological values of feeds for sheep (Cornell Net Carbohydrate and Protein System; CNCPS-S) was expanded to include goats and the name was changed to the Small Ruminant Nutrition System (SRNS). The SRNS uses animal and environmental factors to predict metabolizable energy (ME) and protein, and Ca an

12. Screening of Amazonian plants from the Adolpho Ducke forest reserve, Manaus, state of Amazonas, Brazil, for antimicrobial activity
Tropical forests are species-rich reserves for the discovery and development of antimicrobial drugs. The aim of this work is to investigate the in vitro antimicrobial potential of Amazon plants found within the National Institute on Amazon Research's Adolpho Ducke forest reserve, located in Manaus, state of Amazonas, Brazil. 75 methanol, chloroform and water
