An escape theory model for directionally moving prey and an experimental test in juvenile Chinook salmon

Megan Sabal, Joseph Merz, Suzanne Alonzo & Eric Palkovacs
Prey evaluate risk and make decisions based on the balance between the costs of predation and those of engaging in antipredator behavior. Economic escape theory has been valuable in understanding responses of stationary prey under predation risk; however, current models are not applicable for directionally moving prey. Here we present an extension of existing escape theory that predicts how much predation risk is perceived by directionally moving prey. Perceived risk is measured by the extent...
