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

Animal Conservation, EarlyView.
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.

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

Ibis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Testing the size‐grain hypothesis in a generalist predator: The case of an ant species in the Brazilian savannah

Journal of Zoology, EarlyView.
In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...

Beyond Groups? Consociational Culture and the Representation of Cross‐Segmental Interests

Swiss Political Science Review, EarlyView.
Abstract In deeply divided societies, consociational power‐sharing ensures representation for ethnonational groups but raises questions about cross‐segmental interests. This paper explores “consociational culture,” arguing that consociational systems create a form of political culture which incentivises the use of group‐based categories and identities ...

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

New Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Influence of Hornification Treatment and Fiber Length on the Performance of Recycled Polypropylene Composites

Polymer Composites, Volume 47, Issue 5, Page 4793-4803, 10 March 2026.
Study of the influence of hornification treatment and jute and mallow fiber length on the physical, thermal, and mechanical properties of recycled polypropylene (PP) composites. ABSTRACT The growing accumulation of plastic waste has driven its reuse in the development of new composites, with natural fibers emerging as promising reinforcements. However,
