A theoretical investigation of sympatric evolution of temporal reproductive isolation as illustrated by marine broadcast spawners.

Abstract excerpt

Recent theory suggests that frequency-dependent disruptive selection in combination with assortative mating can lead to the establishment of reproductive isolation in sympatry. Here we explore how temporal variation in reproduction might simultaneously generate both disruptive selection and assortative mating, and result in sympatric speciation. The conceptual framework of the model may be applicable to...
