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. |

... sexual selection, caused by the spatial and temporal clustering of female receptivity, is related to the ecological concept of mean crowding (sensu Lloyd 1967) applied directly to the spatial and temporal aggregation of receptive females.
... females: 2. Like competition for scarce resources, male reproduction is limited by the spatial and temporal availability of sexually receptive females. 3. The intensity of sexual selection depends on the rarity of receptive females in ...
... receptive females. Hence, as explained by Emlen and Oring (1977), the intensity of male-male competition for mates can be expressed as the ratio of adult males to adult females. This operational sex ratio or OSR (we represent this ratio ...
