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. |

... mean, variance, and covariance of male and female reproductive selection explicit and thereby establish a more solid theoretical foundation for future studies on mating systems and strategies. In chapter 1, we explore the Quantitative ...
... mean tail lengths of the breeding and nonbreeding females are the same. By using the selected males and unselected females as parents, fully half of the genes of each offspring, namely, those descending through the females, are not ...
... mean strong natural selection. The absence of fitness differences between individuals (no fitness variance) means that natural selection, and, hence, adaptive evolution, are not possible. Fitness variation determines the maximum rate ...
... mean phenotype in the population before selection, Z, is Z zp(z)dz. [1.2] That is, each value of z in the phenotypic distribution is multiplied by the proportion of the population, p(z), exhibiting that phenotype, and then integrated ...
... mean is given by the product of the parent mean (eq. [1.4]) and heritability. It is also given by adding the product of eq. [1.6] and heritability to the mean before selection. Offspring mean fitness is necessarily less than or equal to ...
