How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, Volume 168, Issue 2, Page 571-587, April 2026.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Molecular Responses to Climate Change: How Warming and Acidification Reshape the Proteome and Phosphoproteome of the Endangered Mira Chub

Ecology and Evolution, Volume 16, Issue 3, March 2026.
ABSTRACT Global environmental change affects organisms, including their physiology. In freshwater ecosystems, where migration is limited, populations often rely on phenotypic plasticity to respond. While transcriptomics has been widely used to study stress responses at the molecular level, less is known about the proteome, which reflects post ...

Microbial biomass and activity in litter during the initial development of pure and mixed plantations of Eucalyptus grandis and Acacia mangium

Revista Brasileira de Ciência do Solo, 2013
Studies on microbial activity and biomass in forestry plantations often overlook the role of litter, typically focusing instead on soil nutrient contents to explain plant and microorganism development. However, since the litter is a significant source of

When Calves Get Vulnerable, Ocelots (Leopardus pardalis) Get Bold: A Camera Trap Record of Opportunistic Foraging in a Fragmented Landscape

Biotropica, Volume 58, Issue 2, March 2026.
We report the first confirmed record of an ocelot (Leopardus pardalis) dragging a newborn calf in a degraded forest fragment of southeastern Brazil. Using camera trap records, we reveal an opportunistic foraging event involving a vulnerable domestic prey within a highly fragmented landscape.

Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.
