Typical results from a transplant experiment: the density of populations (predators per landscape cell) applying rules evolved under stable (prey <i>r</i> = 1.5), cyclic (<i>r</i> = 2.5) and complex (<i>r</i> = 3.5) prey dynamics when they are placed into each of those three conditions.

<p>It is clear that while the strategies that evolve under cyclic or complex prey dynamics prove quite robust within other prey environments, the strategy that evolves under stable prey dynamics results in substantially reduced population density when it is placed in a more complex prey landscape. Mean population sizes are calculated from the 20^th to 30^th generations following transplantation. Transplanted predators had genes equal to the population mean values, the stopping rule based on prey per predator was employed, and per-step mortality <i>c_step</i> was fixed at 0.02 in all cases.
