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. |

... measuring the strength of selection developed by James F. Crow (Crow 1958, 1962), we show that the sex difference in the opportunity for selection is the key to resolving the quantitative paradox between microevolutionary process and ...
... measure ΔI in natural and experimental populations. We suggest that male genetic quality is least important to females in species with strong sexual selection and large values of ΔI, and most important to females in species in which ...
... measuring selection on alternative mating strategies. We provide a new classification scheme for alternative mating strategies based, not on the relative degree to which phenotypes are condition dependent, but instead on the ecological ...
... measure tail lengths of all females and choose those with the longest tails for parents and discard those with shorter tails (fig. 1.2.b). The strength of this selection, Sfemales, is defined just like Smales, but relative to the female ...
... measure the degree to which a particular character is modified within each sex and then attribute its greater ... measurements of the strength of selection. Identifying the mechanism of selection is different from quantifying its ...
