From: Patch depletion, niche structuring and the evolution of co-operative foraging
Per capita food intake for different group sizes in different patch sizes. (a-c) Patch classes III-V respectively. For traveling pairs (PAIRS). Proportion patch depleted by an individual measured according to how many individuals were in a patch during a particular patch visit. Each grid square is the average of all patch visits of a certain patch and group size combination over a 10 year period in simulations with 64 individuals. Note that for very large group sizes (especially in patch class V), there are fewer data points and increased sampling error but the trend is qualitatively the same as in the other environments.
