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.

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

Functional Ecology, Volume 40, Issue 7, Page 2275-2285, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...
