Mating Systems and StrategiesThis book presents the first unified conceptual and statistical framework for understanding the evolution of reproductive strategies. Using the concept of the opportunity for sexual selection, the authors illustrate how and why sexual selection, though restricted to one sex and opposed in the other, is one of the strongest and fastest of all evolutionary forces. They offer a statistical framework for studying mating system evolution and apply it to patterns of alternative mating strategies. In doing so, they provide a method for quantifying how the strength of sexual selection is affected by the ecological and life history processes that influence females' spatial and temporal clustering and reproductive schedules. |

... values of ΔI, and most important to females in species in which sexual selection is negligible and ΔI is small. However, mating systems in which ΔI is small may be evolutionarily unstable. In chapter 6 we propose a statistical framework ...
