Apostatic Selection as an Optimal Foraging Strategy

Two simple optimal diet models are shown to be capable of predicting a variety of effects similar to those of frequency-dependent selection, the type depending on whether the predator can search simultaneously for the prey species it attacks, or not. Intensity of detected selection should decline with increasing prey exploitation.-from AuthorsDept. of Biological Sciences, The Univ., Dundee DD1 4HN, & The Marine Lab., Victoria Rd., Aberdeen, Scotland, UK.
