Effect of predator behavior on spatial scales and stability.

ABSTRACT- Using simulation and deterministic models based on the Rosenzweig-MacArthur Model, we analyzed how various predator foraging behaviors affected predator and prey population dynamics. We considered the effect of different predator and prey spatial scales by allowing single predators to forage in sites potentially containing multiple prey individuals. With a larger predator foraging scale the regions of stability become quite complicated, and bistability arises in the system. Additionally, we examined the evolution of the predator territory size using simulation models.
