| biogeographic variation in behavioral and morphological responses to predation risk. | the expression of prey antipredator defenses is often related to ambient consumer pressure, and prey express greater defenses under intense consumer pressure. predation is generally greater at lower latitudes, and antipredator defenses often display a biogeographic pattern. predation pressure may also vary significantly between habitats within latitudes, making biogeographic patterns difficult to distinguish. furthermore, invasive predators may also influence the expression of prey defenses in e ... | 2013 | 23001623 |
