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. |

... average tail length between the selected males and the unselected males, divided by the standard deviation of male tail length, equals Smales. Similarly, we measure tail lengths of all females and choose those with the longest tails for ...
... average phenotype of the breeding parents is limited by the variation in fitness, the average phenotype of the selected offspring descended from those parents must also be limited. It is in this way that the total variation in fitness ...
... average fitness as well as the average phenotype may change as a result of selection. However, it is more important to understand that there is a relationship between the variance in fitness, VW and the covariance between phenotype and ...
... average in fitness Imales Vmales/X2males and Ifemales among members of that Vfemales/X2females. These sex, X2.i expressions are linked together through the sex ratio and mean fitness. Furthermore, we will show that the variation among ...
... average mating success per male, M, equals the number of females in the ki /Nmales th mating class, multiplied by the number of males in the mith class, added up over all i classes, and then divided by the total number of males. Thus, M ...
