Evolutionarily stable versus fitness maximizing life histories under frequency-dependent selection

摘要

There has been recent interest in using the techniques of quantitative genetics to study optimal life histories under frequency-dependent selection, but a search of the literature has revealed no clear quantitative genetics recursion that incorporatesboth frequency dependence and overlapping generations. This may be due in part to the historical tendency of life-history theory to ignore frequency dependence. Here we provide such a recursion, and use it to explore the general question of how frequency-dependent selection on life-history traits can cause the evolutionarily stable strategies to differ from the point of maximum mean fitness.
