The fear that predators inspire in their prey is a powerful force that can shape ecosystems and maintain biodiversity. These ecological cascades are often mediated by behavior – for instance, fear can drive where prey species choose to move and forage on the landscape. Yet, some of the most basic questions about this important species interaction are obscured in studies involving primates.
