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.

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

Animal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1223-1237, July 2026.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

COMPOSIÇÃO FLORÍSTICA E A CONSERVAÇÃO DE FLORESTAS SECUNDÁRIAS NA SERRA DA CANTAREIRA, SÃO PAULO, BRASIL

Revista do Instituto Florestal, 2011
Florestas secundárias estão seriamente ameaçadas pela expansão urbana na região metropolitana. Alguns remanescentes são protegidos, principalmente em parques estaduais e municipais, mas a maioria dessas florestas está sob risco de supressão pela ...

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1345-1356, July 2026.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

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.

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

Biotropica, Volume 58, Issue 2, March 2026.
Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over
