Figure 14.9 Predator–prey cycles in laboratory mites. When the prey species was given a dispersal advantage, it could colonize predator-free oranges and avoid going extinct. The cycling of the predator population lagged behind the prey population because it required more time to disperse to oranges containing prey and it required time to reproduce after finding prey.
