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. |

... effects of female reproductive life history (multiple mating and multiple reproductive episodes) on the variance in offspring numbers among females. We show how the variance in apportionment of paternity by multiple mating in females ...
... effects on the opportunity for sexual selection. We generate specific predictions about the occurrence of sperm competition, mate guarding, sexual dimorphism, sexual conflict, and alternative mating strategies. We illustrate our scheme ...
... effects on the expected rate of response. Consider first artificial selection on both males and females. After measuring tail lengths of all males, those with long tails are chosen as parents and those with shorter tails are discarded ...
... effects of these mechanisms later (chapters 4 and 5). For now, to allow comparison of the effects of natural and sexual selection on both sexes, we must consider male and female fitness using the same units. Let O be the average number ...
... effects late in life accumulate in populations to a greater degree than deleterious mutations expressed early in life for this very reason: random, early mortality interferes with their expression. Wade (1987) illustrated this same ...
