Ideal free distributions when resources undergo population dynamics.

Original language description

This study examines the influence of optimal patch choice by consumers on resource population dynamics and on consumer distribution in a two patch anvironment. The evolutionarily stable strategy which describes animal distributions across habitat patchesis called the ideal free distribution (IFD) strategy. Two mechanisms that lead to the IFD are: (1) direct consumer competition such as interference, and (2) exploitative competition for resources. This article focuses on the second mechanism by assumingthat resources undergo population dynamics while consumer bundance is fixed. Two models of resource growth are considered in detail: the exponential and the logistic. The corresponding consumer IFD is derived for each of these two models, assuming thatconsumers behave adaptively by moving to the patch which provides them with the highest fitness. This derivation does not require that resources are at an equilibrium, and it provides, for each resource density, the corresponding distribu
