The interactions between a predator and its prey, as well as the interactions between an herbivore and the plants it eats, are some of the most powerful driving forces behind evolution. An optimal antipredator strategy may involve multiple behaviors performed simultaneously or sequentially, yet surprisingly little research has been conducted on how behaviors interact to counter variations in intensity and type of predation risk. 2005.
