1. Birds of Parque Estadual do Tainhas, an important protected area of the highland grasslands of Rio Grande do Sul, Brazil
Abstract Parque Estadual do Tainhas - PET (Tainhas State Park) is a protected area with significant extensions of natural grasslands located in highland grasslands of northeastern Rio Grande do Sul state, Brazil, and recognized as an Important Bird Area. Our aim was to record the bird species richness of PET with a greater sampling effort than previous studi

2. Environmental structure affects taxonomic diversity but not functional structure of understory birds in the southwestern Brazilian Amazon
RESUMO Mudanças nas características ambientais podem influenciar o uso do habitat por aves, afetando o número de indivíduos, a riqueza de espécies e alterando a composição de espécies e estrutura funcional das assembleias. Medidas que avaliam a estrutura funcional de assembléias biológicas constituem uma ferramenta complementar à abordagem taxonô

3. Effects of rainfall on bird reproduction in a semi-arid Neotropical region
ABSTRACT In semi-arid ecosystems, birds commonly use rainfall as a reliable environmental cue to adjust the timing and strength of their reproductive activity. Here we evaluate this hypothesis for a community of birds in the Caatinga (the semi-arid region of northeastern Brazil), using brood patch information and nest abundance. Sampling occurred every 14 da

4. SURVEILLANCE FOR NEWCASTLE DISEASE VIRUS, AVIAN INFLUENZA VIRUS AND MYCOPLASMA GALLISEPTICUM IN WILD BIRDS NEAR COMMERCIAL POULTRY FARMS SURROUNDED BY ATLANTIC RAINFOREST REMNANTS, SOUTHEASTERN BRAZIL
ABSTRACT The geographic overlap between areas of Atlantic rainforest and human activities allows interactions to occur between humans and wild and domestic animals. Despite the great importance of the domestic animal-wildlife-human interface that occurs at poultry farms in terms of public health, economic production and wildlife conservation, there are few s

6. Partitioning of seed dispersal services between birds and bats in a fragment of the Brazilian Atlantic Forest
Community-level network studies suggest that seed dispersal networks may share some universal properties with other complex systems. However, most of the datasets used so far in those studies have been strongly biased towards temperate birds, including not only dispersers, but also seed predators. Recent evidence from multi-taxon networks suggests that seed

7. Comunidades de aves frugívoras e nectarívoras e disponibilidade de recursos em dois estádios sucessionais de regeneração de Mata Atlântica.
The availability of food resources in different degrees of regeneration of a forest may contribute to possible variations in species abundance and composition of bird communities. The main objective of this study is to investigate the relationship between the structure of frugivores and nectarivores bird communities and the availability of food resources - f

8. Editorial
Even though the caatinga has been identified as an important area of endemism for South American birds, few studies have been conducted on the distribution, evolution and ecology of birds in this biome. Understanding how habitats contribute to maintain the regional bird diversity is extremely important. In this study, carried out in the backwoods of the stat

9. O valor de corredores florestais para a conservação de aves em paisagens fragmentadas / The value of forest corridors to bird conservation in fragmented landscapes
Habitat loss and fragmentation are major threats to biodiversity. Habitat corridors linking remnants are a popular strategy to reduce the negative effects of habitat loss and fragmentation. However, the evaluation of the effectiveness of corridors in conservation is limited by lack of empirical evidence, especially in the neotropics. In this thesis we empiri

10. Ecologia populacional de Euterpe edulis e os efeitos da introdução de Euterpe oleracea na floresta atlântica no Estado de São Paulo
The main objectives of this dissertation were to evaluate the risks of introduction of Euterpe oleracea in the Atlantic Rainforest and its influence over a native population of Euterpe edulis. We investigated the ecological and morphological features of these species also including pre-existing data about hybrids experimentally produced between them (Chapter

11. Hyper abundant mesopredators and bird extinction in an Atlantic forest island
Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil. Anchieta Island has the highest density of mammals of the entire Atlantic forest, especially nest predators suc

12. Composição da avifauna e frugivoria por aves em um mosaico de vegetação secundária em Rio Claro, região centro-leste do Estado de São Paulo
The study of birds was conducted in a secondary vegetation mosaic of 44 ha, located in the central-eastern Sao Paulo State, between 2007 December and 2009 January. Were among the goals: get the list of bird species throughout the area, evaluate the community structure of a small fragment and a mixed reforestation representing the vegetation mosaic, and compa
