摘要

Predators have a remarkable evolutionary effect on the morphology and behavior of their prey (1). In their attempt to reduce the likelihood of being killed, prey species have evolved a variety of coun-terstrategies, including the ability to communicate directly with their predators to discourage pursuit or attack. Stotting, when ungulates jump up in a stereotypical stiff-legged display, is a visual signal of unprofitability to hunting carnivores, and the alarm calls and mobbing behavior seen in birds and mammals may also discourage pursuit.
