Anti-Predator Strategies of Cathemeral Primates: Dealing with Predators of the Day and the Night

摘要: The entire evolutionary history of the order Primates has occurred in ecological contexts where all primates, like other animals (Vermeij, 1987; Endler, 1991, p. 176), are, at least, risk predation some point their lives (Hart & Sussman, 2005). These predator-prey relationships can be conceived as interspecific, asymmetric “attack-defense” arms races that give rise to diffuse coevolutionary effects (Dawkins Krebs, 1979; Janzen, 1980). Predators and prey exhibit interactions because selective pressure predators on species is stronger than predators. nature these been termed “life-dinner principle” 1979): Failure a predator’s part means it lost meal, but failure prey’s dramatically increases its likelihood being meal (e.g., Terborgh, 1983; Vermeij, Lima Dill, 1990; 176; Stanford, 2002).
