1. Avaliação dos conflitos no uso da terra na bacia hidrográfica do ribeirão Lamarão, Distrito Federal
Resumo A falta de estudos e a constante degradação das Áreas de Preservação Permanentes (APPs) têm representado um dos maiores entraves para o planejamento de ações conservacionistas, além de favorecer o uso de estratégias inadequadas de manejo das bacias hidrográficas. Dessa forma, este estudo teve como objetivo, delimitar de maneira automática

2. Wood-decay fungi (Agaricomycetes, Basidiomycota) in three physiognomies in the Savannah region in Brazil
RESUMO Este estudo foi realizado visando Cerrado do Brasil). Visando entender se há correlações entre fisionomia e diversidade da vegetação (disponibilidade de substratos), grau de preservação, história de manejo da área e a proximidade de cursos de água com a diversidade de fungos decompositores de madeira. 796 espécimes foram coletados em quatro

3. Influence of vegetation physiognomy, elevation and fire frequency on medium and large mammals in two protected areas of the Espinhaço Range
ABSTRACT The objectives of this study were to determine the richness of medium and large mammal species in two protected areas of the Espinhaço Mountain Range, state of Minas Gerais, Brazil; and to investigate the factors affecting the occurrence of those species. To accomplish that we placed 49 camera traps activated by heat and motion at Rio Preto State P

4. Influência da estrutura da vegetação de um fragmento florestal nas características físicas e químicas da água e no funcionamento do ecossistema de um córrego rural
Riparian ecosystems are being rapidly degraded due to deforestation for conversion of natural areas to agriculture, pasture, and urban development. In rural areas, riparian forest remnants can be very important for biodiversity conservation and for the maintenance and improvement of water physical and chemical characteristics as the deforested stream passes

5. MAPEAMENTO DE ÁREAS ÚMIDAS E BANHADOS NA MICROBACIA DO RIO AMANDAÚ, REGIÃO NOROESTE DO RIO GRANDE DO SUL / MAPPING OF MOISTURE SOIL AND WETLANDS IN THE WATERSHED OF THE AMANDAU RIVER, NORTHWEST REGION OF RIO GRANDE DO SUL
The wetlands are one of the worlds most productive places, with high rates of biological diversity and also highly impacted. In this context, this project was aimed at mapping the Wetlands Ecosystems present in the soil moisture in the watershed of the Amandau River (Watershed U30), using orbital images and clinographic terrain maps. This research was struct

6. Evaluation of the lisem model for the simulation of hydrosedimentologic processes in a small rural catchment on the basalt slopes of Rio Grande do Sul, Brazil / Avaliação do modelo LISEM na simulação dos processos hidrossedimentológicos de uma pequena bacia rural localizada nas encostas basálticas do Rio Grande do Sul
The intensive cultivation of the areas of southern Brazil that have poor agricultural potential (shallow soils on steep, basaltic hillsides) has contributed to the degradation of the environment by increasing rates of soil erosion and sediment yields. In this study, traditional monitoring methods have been combined with concurrent mathematical modeling to ve

7. The influence of habitat integrity and physical-chemical water variables on the structure of aquatic and semi-aquatic Heteroptera
This work aimed to assess the effect of certain physical-chemical variables and the Habitat Integrity Index (HII) have on an aquatic and semi-aquatic heteropteran community. We collected in five streams (from 1st to 4th order) that differed in habitat integrity, in order to test 1) whether heteropteran richness decreases with the Habitat Integrity Index; and

8. Remnant vegetation diagnose aiming forest restoration and conservation in the municipality of Paulínia, São Paulo State / Caracterização da vegetação remanescente visando à conservação e restauração florestal no município de Paulínia - SP
In biological conservation, forest fragmentation is defined as a separation or nonnatural disconnection of wide areas in spatially segregated fragments, generating a reduction of habitat types and the split of remnant habitat in smaller isolated units. The magnitude and extension of these landscape alterations are influenced by size, connectivity, shape, con

9. Niche characterization of Sporophila spp. (Aves: Emberizidae) and its relation to microhabitat in palm swamp areas near Uberlândia, MG / Caracterização de nicho de Sporophila spp. (aves: Emberizidae) e sua relação com a estrutura de microhabitat em áreas de vereda de Uberlândia, MG
The relative importance of each environmental factor in structuring birds community seems to be variable, and each species exhibits a distinct and specific response to environmental characteristics and their changes. Some granivorous birds can perform seasonal migrations in search of good seeds. They often include the brazilian cerrado, both for breeding and

10. Importance of riparian corridors for the fauna: small mammals in forest patches, surrounding matrix and linear elements in an Atlantic forest fragmented landscape / Importância dos corredores ripários para a fauna - pequenos mamíferos em manchas de floresta, matriz do entorno e elementos lineares em uma paisagem fragmentada de Mata Atlântica
This master thesis aimed to evaluate the importance of riparian corridors for the fauna in an Atlantic Forest fragmented landscape. In four systems composed by fragment corridor fragment, we evaluate both the small mammal assemblage (chapter 2) and the habitat quality measured through the vegetation structure and food resources availability for the fauna (ch

12. Composition and trophic structure of fish communities in the Ribeirão Bananal sub-basin, Parque Nacional de Brasília, biome Cerrado, DF / Composição e estrutura trófica da comunidade de peixes de riachos da sub-bacia do Ribeirão Bananal, Parque Nacional de Brasília, bioma Cerrado, DF
The purpose of this study was determined the composition and the trophic structure of fish communities in the Ribeirão Bananal sub-basin, which belongs to a well preserved Cerrado area in the National Park of Brasília, Brazil. Furthermore, due to a marked sazonality in this biome, it was examined the influence of environmental variations on the fish specie
