1. PLANT RICHNESS AND LIFE FORM DIVERSITY ALONG VEGETATION AND FOREST USE GRADIENTS IN NORTHWESTERN PATAGONIA OF ARGENTINA
ABSTRACT The imbalace between the increase in the demand and the decrease in the supply of products from natural forests, partly explains the on-going development of exotic tree plantations. In northwestern Patagonia of Argentina, Pinus ponderosa (Pinaceae) afforestation plays a key role in ameliorate degraded soils, but may also reduce biodiversity. The eco

2. Classificação de fragmentos florestais urbanos com base em métricas da paisagem
Resumo A urbanização no município de Campinas-SP e região ocorreu de forma rápida e intensa, provocando acentuadas alterações na paisagem e resultando em uma expressiva degradação das áreas florestais e da cobertura vegetal natural. Este fenômeno deu origem a um processo de fragmentação florestal bastante intenso. Neste contexto, mapear estes fr

3. CONEXÃO ENTRE FRAGMENTOS DE VEGETAÇÃO COM BASE EM SISTEMAS DE INFORMAÇÕES GEOGRÁFICAS / Connection between fragments of vegetation based on Geographic Information Systems
Uma das formas de conexão entre fragmentos de vegetação, o corredor ecológico, constitui-se em uma das estratégias para a conversação da biodiversidade e, no transcorrer da tomada de decisão sobre sua localização, os Sistemas de Informações Geográficas (SIGs) podem contribuir como ferramenta efetiva de apoio a esse processo. Nesse contexto, o pr

4. GENÉTICA, DISTRIBUIÇÃO E CONSERVAÇÃO DO GAVIÃO-REAL (Harpia harpyja) NO BRASIL
The harpy eagle occurs in the forests of the Neotropical region; it is widely distributed in Brazil where its occurrence has been principally registered in the Amazonian and Atlantic rainforests. Between these two biomes exists a corridor of open vegetation with forest connections where this species has also been registered. Brazilian forests have been drast

5. Small mammals communities in the forest fragments connected by vegetation corridors in the south of Minas Gerais / Comunidades de pequenos mamÃferos em fragmentos florestais conectados por corredores de vegetaÃÃo no sul de Minas Gerais
The forest fragmentation is one of the main threats for the biodiversity. For the fauna, the consequences associated to the forest fragmentation are the original habitat loss, reduction of the fragment size and isolation, which create a number of negative effects over the wild populations, affecting the species richness, the abundance and the animal species

6. Genetic differentiation and temporal aspects of the fine-scale genetic structure in fragments-vegetation corridors: Inferences from a dioecious-dominant neotropical tree / Genetic differentiation and temporal aspects of the fine-scale genetic structure in fragments-vegetation corridors: Inferences from a dioecious-dominant neotropical tree
Foram estudados os padrÃes da diferenciaÃÃo genÃtica, da biologia reprodutiva e da estrutura genÃtica e demogrÃfica em escala espacial fina em uma paisagem conectada com interessante histÃria de conversÃo humana do hÃbitat, que se iniciou hà dois sÃculos, durante o perÃodo colonial. Nessa paisagem, Protium spruceanum à uma arbÃrea nativa abunda

7. Diversidade genÃtica de Myrcia splendens (SW.) DC. (Myrtaceae) por marcadores ISSR em sistema corredor-fragmento semideciduais no Sul de Minas Gerais / Genetic diversity of Myrcia splendens (SW.) DC. (Myrtaceae) by ISSR markers in a system semidecidual corridor-fragment in the South of Minas Gerais
In the South of Minas Gerais State, the landscape is mainly characterized by fragmented ecosystems. So, the presence of vegetation corridors has a great ecological importance gene flow of plants and animals. In the regional the corridors are narrow, between 3 and 6m and resulted from secondary vegetation colonization trenches, built for land division purpose

8. 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

9. Contribuições para gestão urbana :corredores de vegetação para avifauna em Porto Alegre, RS
Abstract: The green tunnel is a landscape structure specific to urban arborization, formed by the joining of the canopies of trees along the roads. This dense arborization of the roads visually forms a suspended linear mass over the streets, qualifying the environment constructed by the different contributions generated by the presence of vegetation. Based u

10. Visões de um Paisagismo Ecológico na Orla do Lago Paranoá
This master thesis started from the idea that the landscapes models currently adopted on the shore of the Lake Paranoa arent contributing properly for the maintenance of the native ecosystems. In this context, the restoration of green corridors, allocated in strategic positions by the connection of environmental preservation areas, could act as feasible stra

11. ANÁLISE ESPACIAL DOS FRAGMENTOS FLORESTAIS NA ÁREA DO PARQUE NACIONAL DOS CAMPOS GERAIS, PARANÁ
The fragmentation of habitats figures into the most serious threats to the conservation of ecosystems nowadays. As a direct result of the human action, the fragmentation of the natural environment produces different environments that modify the dynamic of ecological relations among fauna, flora and the abiotic system. The rupture of a landscape unit generate

12. Medium and large-sized mammals in fragments of forest in "Serra do Carrapato", Lavras/MG. / MamÃferos de mÃdio e grande porte em fragmentos florestais na Serra do Carrapato, Lavras/MG.
This work was carried out in a matrix of agricultural fields and pastures where small fragments of forest are connected by vegetation corridors inserted in transitional Mata AtlÃntica and Cerrado landscape, in Lavras/MG. The area of research is composed by five forest fragments denominated F1, F2, F3, F4 and F5, with a 35 ha total area. This work was conduc
