A test of frequency dependent selection in the evolution of a generalist phenotype

Stephanie Blain, Louise Chavarie, Mackenzie Kinney & Dolph Schluter
A solitary population of consumers frequently evolves to the middle of a resource gradient and an intermediate mean phenotype compared to a sympatric pair of competing species that diverge to either side via character displacement. The forces governing the distribution of phenotypes in these allopatric populations, however, are little investigated. Theory predicts that the intermediate mean phenotype of the generalist should be maintained by negative frequency dependent selection, whereby alternate extreme phenotypes are favored because...
