Abstract
Derives a population-dynamic model of sedentary consumers that compete exploitatively for sedentary resources. The area over which each individual uses resources is an explicit parameter of the model. In the limit as this area approaches infinity, the model converges to previously studied models of consumer-resource dynamics. The evolution of resource partitioning among the consumer species is then examined. The amount of evolved resource partitioning decreases to zero as resource use becomes increasingly local. This results from an effect of the spatial scale of resource use on the spatial pattern of resource availability that increases the evolutionary contribution of intraspecific competition relative to interspecific competition. -Author
