Evidence

Peer-reviewed

Geography

Minas Gerais, Brazil

System

Atlantic Forest fragments in agricultural / plantation matrix

## WHAT THE EVIDENCE SAYS

Mist-net and acoustic surveys detected 34 species/sonotypes. Across a 0–68% Eucalyptus-cover gradient, predicted functional richness and dissimilarity fell while functional redundancy rose; unique larger-bodied and diverse dietary guilds were less associated with Eucalyptus-dominated landscapes.

## WHY IT MATTERS / OUR READ

Species counts alone can miss functional homogenization in production landscapes. Plantation extent and landscape composition may matter even when bats remain present.

## CAVEATS / UNCERTAINTY

The study is observational across 12 fragments in one heavily altered landscape, so it cannot isolate plantation cover from every correlated land-use process or establish a universal plantation threshold.
