    Abstract

    Abstract If the food distribution contains spatial pattern, the food density in a particular patch provides a forager with information about nearby patches. Foragers might use this information to exploit patchily distributed resources profitably. We model the decision on how far to move to the next patch in linear environments with different spatial patterns in the food distribution (clumped, random, and regular) for foragers that differ in their degree of information. An ignorant forager is uninformed a [KEYWORDS: Area-restricted search ; Information state ; Foraging scale ; Marginal value theorem ; Optimal foraging strategies ; Prior knowledge ; Spatial heterogeneity]
