1. Mollusks associated with the Avicennia schaueriana (Magnoliophyta: Acanthaceae) roots of a hypersaline estuary in northeastern Brazil
Resumo Objetivo Avicennia schaeuriana é uma das seis espécies que compõem as florestas de mangue do Brasil e formam franjas de mangue ao longo dos cursos d’água, sendo diretamente influenciadas pela maré. As raízes do mangue A. schaeuriana atuam como um dos microhábitats utilizados pela biodiversidade de invertebrados do ecossistema estuarino. Este

2. Land use in Permanent Preservation Areas of Grande River (MG)
ABSTRACT The Brazilian Forestry Code established the Permanent Preservation Areas (PPAs) to preserve environmentally significant areas, such as the banks of waterways. Grande River is an important Brazilian river whose watercourse contains several hydroelectric plants, with few PPAs containing original features. Thus, this study analyzed land use in PPAs of

3. Sediment Morphology, Distribution, and Recent Transport Dynamics in a Reforested Fragment
Abstract Erosion generates large amounts of sediment, which may be deposited at the site of origin, on the slope of a hill, or along waterways. The transportability of each type of sediment by runoff and its potential for subsequent deposition largely depends on its morphological features and particle size distribution. The aim of this study is to describe a

4. Agronomic and Economic Efficiency of Common-Bean Inoculation with Rhizobia and Mineral Nitrogen Fertilization
ABSTRACT Management of biological nitrogen fixation in common bean still requires improvement. The objective of this study was to verify the compatibility of nitrogen fertilization with biological N2 fixation to increase common bean yield and profitability. Four field experiments were performed in four municipalities of Minas Gerais, Brazil, during the 2009

5. Network modelling of palm biodiesel plants to supply the isolated electric power systems of Pará state
Despite the great advance brought by the National Interconnected System (NIS), which is able to provide clean hydroelectric power to almost all Brazilian customers, there are still cities supplied by power generated from fossil fuel, which are subsidized by taxes, they are called Isolated Electric Power Systems (IEPS). Pará State, that has 34 cities with IE

6. Socio-economic and spatial determinants of anthropogenic predation on Yellow-spotted River Turtle, Podocnemis unifilis (Testudines: Pelomedusidae), nests in the Brazilian Amazon: Implications for sustainable conservation and management
Human expansion has drastically affected wildlife species across Amazonian waterways and the continued increase in rural populations across Amazonia is likely to increase pressure on widely exploited chelonian species. The lack of information evaluating determinants of human consumption patterns limits the effective implementation of conservation strategies.

7. DIAGNÓSTICO AMBIENTAL DO MEIO FÍSICO DO CAMPO DE INSTRUÇÃO DE SANTA MARIA (CISM) / ENVIRONMENTAL DIAGNOSIS OF THE PHYSICAL ENVIROMENT AT CAMPO DE INSTRUÇÃO DE SANTA MARIA (CISM)
The Campo de Instrução de Santa Maria (CISM) is a military training area for armored troops. Such practices have caused environmental impacts related to the destruction of vegetation, erosion, and siltation of waterways. Since there is no environmental data for the area, the following research aimed to develop an environmental diagnosis of the physical env

8. IdentificaÃÃo de Ãreas de preservaÃÃo permanente e de conflitos potenciais de uso no setor centro-leste do planalto de Francisco BeltrÃo â SW/PR / Identification of areas for permanent preservation and potential conflicts of use sector in central eastern highlands of Francisco BeltrÃo â SW/PR
The survey shows permanent preservation areas and use of potential conflicts in the sector East-Central Plateau of Francisco BeltrÃo, Southwest of ParanÃ. The analysis was performed based on the recognition of the physical topography and hydrography characteristics as well as the existing land use in the area using geoprocessing techniques. The sectors of

9. Fluxos hídricos na microbacia do córrego do Queixada no município de Jataí / Water flows in the stream watershed queixada in the city of Jataí (Go)
The diagnosis of hydrological flow and the rainfall interception by vegetation is justified by the need for knowing the influence of these elements in river basins, where weeds and appropriate use of land are responsible for maintaining the quality of the slopes, avoiding erosion, soil loss, silting of waterways and induces the maintenance of groundwater res

12. Impactos na produção de energia nas usinas hidroelétricas do rio Tietê em decorrência do transporte hodroviário / Impacts on energy production in hydroelectric plants of the Tiete river as a result of water transport
A dissertação propõe a utilização de metodologias de otimização e simulação para avaliação de impactos energéticos para uma cascata de aproveitamento múltiplo (navegação e geração hidrelétrica), considerando-se diversos cenários de crescimento setoriais e incertezas hidrológicas. A eficiência dos segmentos de transporte e energia é fund
