Figure WN28.3. A stable limit cycle in abundance of predator and prey. The model is the same as that in Figure WN28.2, except that now, predator fitness increases with predator density (see text). (A) Trajectories followed as the predators invade (black lines from unstable equilibrium [red] at lower right) and as the population diverges from the unstable interior equilibrium (brown lines running out from the central equilibrium [red]). (B) Changes through time as the population diverges from the unstable interior equilibrium to a steady limit cycle.
