Local Knowledge and Human–Wildlife Conflict in the Conservation of the Harpy Eagle (Harpia harpyja) in Its Main Refuge in the Atlantic Forest

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The Harpy Eagle (Harpia harpyja), a top predator of Neotropical forests, faces severe threats across its range, including in the Atlantic Forest. Using 50 years of occurrence records, including nests and multiple age classes, we document the species' persistence in one of its last reproductive refuges while revealing ongoing human–wildlife conflicts ...

Reusable SERS Substrate Based on AuNP/PS‐b‐P2VP Nanocomposites With Photocatalytic Activity

Journal of Raman Spectroscopy, Volume 57, Issue 5, Page 828-839, May 2026.
We developed a bifunctional SERS substrate by assembling AuNPs on PS‐b‐P2VP thin films, capable of both sensitive molecular detection and UV‐assisted self‐cleaning. The platform demonstrates excellent reusability over four adsorption–degradation cycles, driven by a hot‐hole‐mediated photocatalytic mechanism without semiconductors.
