Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat-driven risk perception and...

🧪 ETHOLOGY: Who makes roe deer more vigilant? 👀🦌
Torretta et al. found that human disturbance, not wolf presence, is linked to higher vigilance in roe deer. Deer were also less vigilant in natural habitats and in larger groups. Read here, it's #OpenAccesss: doi.org/10.1111/eth.... #PredationRisk
