Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Riparian Amphibian and Reptile Assemblages in Streams Along a Forest Regeneration Gradient in the Ecuadorian Chocó

Biotropica, Volume 58, Issue 6, November 2026.
ABSTRACT While primary forests are declining, regenerating habitats are becoming increasingly common. In fragmented environments, streams may function as corridors between forest remnants for riparian and aquatic species. However, the responses of stream‐associated species to forest regeneration remain understudied.

Biogeographic Disconnect and Biotic Homogenization in the Heart of the Amazon: Dominance of Exotic Species in Urban Trees

Biotropica, Volume 58, Issue 5, September 2026.
Exotic taxa dominate the urban woody flora, with potentially invasive species posing a direct risk to adjacent primary forest remnants. Historical management has favored a simplified, cosmopolitan species pool over regional biodiversity. There is failure to implement local native‐priority mandates, offering concrete ecological targets for urban ...

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

Animal Conservation, Volume 29, Issue 4, Page 421-431, August 2026.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

Ecological and functional effects of habitat conversion and seasons on fruit‐feeding butterfly assemblages in tropical dry forests Efeitos ecológicos e funcionais da conversão do habitat e da sazonalidade sobre assembleias de borboletas frugívoras em florestas tropicais secas

Ecological Entomology, Volume 51, Issue 4, Page 760-773, August 2026.
Land‐use change and seasonality shape the taxonomic, functional and phylogenetic diversity of fruit‐feeding butterflies in tropical dry forests. Pastures reduce phylogenetic diversity and increase wing fluctuating asymmetry, while taxonomic and functional diversity is greater in the wet season than in the dry season.
