摘要

Predation can shape virtually every aspect of an organism's behavior, life history, and evolution (e.g., Dill 1987; Godin 1995; Reznick et al. 1996). Thus, understanding how organisms respond to perceived predation risk or the actual presence of predators is central to understanding their foraging decisions, habitat use, reproductive effort, and other proximate behaviors (e.g., Sih 1982; Ydenberg and Dill 1986; Gillam and Fraser 1987; Heithaus and Frid 2003). For harbor seals (Pboca vitulina ricbardii), predation (or the risk of predation) is thought to be common enough to influence habitat utilization (Calambokidis et al. 1987; Nordstrom 2002).
