Invasive rats are stopping small mammals from returning to Madagascar's regenerating forests: Study

What it means

This study shows that invasive rats are actively preventing native small mammals from recolonizing forests in Madagascar that are regrowing after deforestation. Even when the forest habitat recovers, the presence of rats suppresses the return of endemic species, which undermines restoration efforts.

Accuracy & sources

The claim is based on a peer-reviewed scientific paper, reported by Phys.org. The reporting appears to closely follow the study's findings, but the specific methodology and effect sizes cannot be verified from the given information.
