Diversity and dominance in bird assemblages across habitats in the Ñeembucú wetlands complex
Biotropica, Volume 56, Issue 5, September 2024.We analyzed how the composition of neotropical bird assemblages vary among habitats (riparian forests, natural grasslands, savannas, and anthropized sites) in the Ñeembucú Wetlands Complex, the largest wetland system in Paraguay. We found a high bird richness (209 species) that contrasted with a pattern of dominance by a small set of 16 species that ...

Distinct bird communities in forests and fruit farms of Caatinga landscapes
Ibis, Volume 166, Issue 3, Page 1081-1091, July 2024.Agricultural expansion and intensification drive changes in bird assemblages and contribute to the homogenization of communities. By working across the semi‐arid biome of the Caatinga in northeastern Brazil, this study is the first to compare the bird communities found in intensively managed fruit farms with those in remnant Caatinga forest patches. We

Evolution of avian heat tolerance: The role of atmospheric humidity
Ecology, Volume 105, Issue 5, May 2024.Abstract The role of atmospheric humidity in the evolution of endotherms' thermoregulatory performance remains largely unexplored, despite the fact that elevated humidity is known to impede evaporative cooling capacity. Using a phylogenetically informed comparative framework, we tested the hypothesis that pronounced hyperthermia tolerance among birds ...

Delay in plumage maturation in Sporophila (Aves:Thraupidae)
, 2019 O atraso na maturação da plumagem ocorre em espécies de aves que adquirem a plumagem adulta após sua primeira estação reprodutiva potencial. Este fenômeno, bem conhecido na região temperada, ainda é mal compreendido nos trópicos.

PLoS ONE, 2020 The small Neotropical finches called capuchinos are outstanding because they have experienced one of the most recent and explosive avian radiations ever documented for birds. Despite very low morphological and niche divergence among species, many of them
