Summary

The expectation of the ideal free distribution is a functional response in which intake is constant in all sites and, if interference is low, an aggregative response in which all individuals cluster in the high prey density sites. Incorporating individual differences in competitive ability results in a functional response in which intake increases with prey density and an aggregative response in which individuals are more evenly distributed.
