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.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

Conservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

How Food Geometry and Toughness Influence Ingestive Patterns in Lemurs

American Journal of Primatology, Volume 88, Issue 7, July 2026.
Initial bite placement is influenced by food toughness and geometry. Species‐specific feeding strategies reflect differences in masticatory morphology and functional flexibility. Lemur catta is more likely to use the postcanine tooth row; Propithecus verreauxi prefers anterior biting. ABSTRACT We investigate the extent to which food toughness, geometry,

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Sobre a conexão entre alguns modelos físicos não-lineares

Revista Brasileira de Ensino de Física
Neste trabalho revisamos alguns dos sistemas não-lineares mais paradigmáticos e desvendamos algumas das suas surpreendentes interligações. Os problemas de interesse, descrito matematicamente pelas equações de sine-Gordon, Toda e KdV, generalizam modelos ...

When conservation meets contagion: Mapping yellow fever risk to guide vaccination in an endangered primate

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Spatial projections revealed high‐risk areas for YF transmission, highlighting priority zones for targeted vaccination efforts in GLTs. By integrating disease ecology into conservation planning, this study offers a scalable framework for spatially informed interventions aimed at mitigating disease‐driven declines in threatened species.
