1. Hysterosalpingography: Balloon Catheter or Metal Cannula?
ABSTRACT The Brazilian Atlantic Forest (BAF) is one of the biodiversity hotspots, but in the last decades, it has been fragmented due to agricultural and urban-industrial expansion, which has a strong impact on forest fragments. The goal of this study was to analyze the Biotic Integrity Index (BII) in fragments of BAF in two medium-sized cities in Southeaste

3. 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

4. Influences of the area, shape and connectivity of coastal lakes on the taxonomic and functional diversity of fish communities in Southern Brazil
ABSTRACT In this study we investigated the influence of landscape variables on the alpha taxonomic and functional diversity of fish communities in coastal lakes. We built an analytical framework that included possible causal connections among variables, which we analyzed using path analysis. We obtained landscape metrics for the area, shape and connectivity

5. Landscape Ecology in a Watershed of the Ocoy River, Western Parana State, Brazil
ABSTRACT This study evaluated the landscape structure of a watershed located in a region considered strategic for the implementation of the Paraná River Biodiversity Corridor. Based on land-use/land-cover mapping, four different scenarios were generated: 1) real situation, 2) considering the edge effect, 3) without Permanent Preservation Areas (APPs), and

6. Estimating Stand Height and Tree Density in Pinus taeda plantations using in-situ data, airborne LiDAR and k-Nearest Neighbor Imputation
ABSTRACT Accurate forest inventory is of great economic importance to optimize the entire supply chain management in pulp and paper companies. The aim of this study was to estimate stand dominate and mean heights (HD and HM) and tree density (TD) of Pinus taeda plantations located in South Brazil using in-situ measurements, airborne Light Detection and Rangi

7. Bird diversity along a gradient of fragmented habitats of the Cerrado
ABSTRACT Understanding the factors that affect biodiversity is of central interest to ecology, and essential to species conservation and ecosystems management. We sampled bird communities in 17 forest fragments in the Cerrado biome, the Central-West region of Brazil. We aimed to know the communities structure pattern and the influence of geographical distanc

8. Plant diversity in hedgerows amidst Atlantic Forest fragments
Hedgerows are linear structures found in agricultural landscapes that may facilitate dispersal of plants and animals and also serve as habitat. The aim of this study was to investigate the relationships among diversity and ecological traits of woody plants, hedgerow characteristics (size, age, and origin), and the structure of the surrounding Atlantic Forest

9. CARACTERIZACIÓN Y CUANTIFICACIÓN DE FRAGMENTOS DE BOSQUE NATIVO, EN UN SECTOR DEL SECANO INTERIOR DE LA REGIÓN DEL MAULE, CHILE
ABSTRACT In general, the Mediterranean forests have suffered high levels of fragmentation, mainly by anthropogenic action, as result of the productive activities of agriculture and livestock, human settlements and forest plantations of fast growing exotic species, leading to loss of continuity of natural forests, and thus a decrease of biodiversity. In this

10. Padrões de distribuição de mamíferos de médio e grande porte em paisagens fragmentadas / Distribuition patterns of medium and large size mammals in fragmented landscapes
Habitat fragmentation is defined as the breaking of a continuous habitat in patches or fragments. This process leads to environmental changes capable of affecting communities in different ways, causing species composition changes. Beta diversity measures can show the variation between the composition of different communities, where two ecological patterns ca

11. PADRÕES ESTRUTURAIS E FUNCIONAIS DAS PAISAGENS RIPÁRIAS DOS RIOS PITANGUI E JOTUBA NO PRIMEIRO PLANALTO PARANAENSE PONTA GROSSA 2012
A Ecologia de Paisagem é a ciência que estuda as relações entre padrões estruturais e processos em paisagens. Uma de suas maiores preocupações, atualmente, é a busca de parâmetros adequados para a modelagem ecológica em distribuições espaciais. Este estudo analisa as zonas ripárias dos rios Pitangui e Jotuba, situados no Primeiro Planalto Parana

12. Composição e abundância das espécies de anfíbios e répteis em uma paisagem fragmentada de Mata Atlântica no Estado do Rio de Janeiro / Composição e abundância das espécies de anfíbios e répteis em uma paisagem fragmentada de Mata Atlântica no Estado do Rio de Janeiro / Composição e abundância das espécies de anfíbios e répteis em uma paisagem fragmentada de Mata Atlântica no Estado do Rio de Janeiro / Composition and abundance of amphibians and reptile species in a fragmented landscape of Atlantic Rainforest in Rio de Jaeiro State / Composition and abundance of amphibians and reptile species in a fragmented landscape of Atlantic Rainforest in Rio de Jaeiro State / Composition and abundance of amphibians and reptile species in a fragmented landscape of Atlantic Rainforest in Rio de Jaeiro State
A composição e a abundância de espécies de anfíbios e répteis podem se modificar em paisagens fragmentadas, devido a uma série de fatores de degradação como a redução e o isolamento das áreas de hábitat e a ação do efeito de borda. Neste estudo, procuramos avaliar a composição e abundância de espécies de anfíbios e répteis em uma paisage
