Abstract. The role of plant defensive compounds has often been studied within the purview of consumer diet choice. However, consumers are often confronted with foods distributed within depletable patches. To investigate the complication of resource depletion, I merged a consumer--resource model of nutritional relationships between foods with the technique of giving-up densities for measuring foraging behavior in depletable food patches. Theory predicts that foods containing plant defenses that act as digestibility reducers (e.g., lignins and tannins) will be relatively less depleted under higher predation risk than will foods without defenses. In ...
