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. |

... frequency of hidden or stolen copulations, now being revealed by molecular paternity analysis, is the expected equilibrium signature of both the spatial runaway process based on female aggregation and the temporal runaway process based ...
... frequency of such individuals in a population be p(z) (fig. 1.11). The mean fitness of this population before selection, is, by definition, W W(z)p(z)dz. [1.1] That is, the fraction of the population exhibiting each phenotypic ...
... frequencies are connected through the sex ratio R. The average number of mates per male, R, equals the average number ... frequency of successful males, pm, as [1 p0], we find p0 1 (R/H) or [1.17] p0 1 (1/[ROH]). [1.18] It is clear from ...
... frequency of males with no mates at all and p5 is the frequency of males with five mates, i.e., k 5. The frequency of successfully mating males, pm, is equal to the sum Σpj (1 p0). For all categories of mating males, we assume that the ...
... frequency of nonmating males can often be estimated from knowledge of R and H. The average density of females per patch, m, equals the sum of all females over all patches, divided by the total number of patches, or m mi/M. [2.1] Note ...
