Responses of a large herbivore to predation risk are modulated by intrinsic and extrinsic factors

open access: yesEcosphere, Volume 16, Issue 5, May 2025.
Abstract Prey species can perceive and respond to spatiotemporal variation in predation risk to increase survival. In addition to adjusting spatial and temporal activity patterns to avoid predation, prey employ other antipredator behaviors, such as vigilance and fleeing, and these behaviors can be further modulated by intrinsic, environmental, and ...
