Consumers face numerous risks that can be minimized by incorporatingdifferent life-history strategies. How much and when a consumer adds to itsenergetic reserves or invests in reproduction are key behavioral andphysiological adaptations that structure much of how organisms interact. Herewe develop a theoretical framework that explicitly accounts for stochasticfluctuations of an individual consumer's energetic reserves while foraging andreproducing on a landscape with resources that range from uniformly distributedto highly clustered. First, we show that optimal life-history strategies varyin response to changes in the mean productivity of the resource landscape,where depleted environments promote reproduction at lower energetic states,greater investment in each reproduction event, and smaller litter sizes. Wethen show that if resource variance scales with body size due to landscapeclustering, consumers that forage for clustered foods are susceptible to strongAllee effects, increasing extinction risk. Finally, we show that the proposedrelationship between consumer body size, resource clustering, and Alleeeffect-induced population instability offers key ecological insights into theevolution of large-bodied grazing herbivores from small-bodied browsingancestors.

Scaling of the risk landscape drives optimal life history strategies and the evolution of grazing
