The aim of this review is to consider the potential benefits that females may gain from mating
more than once in a single reproductive cycle. The relationship between non-genetic and …

Theory suggests that male fitness generally increases steadily with mating rate, while one or
a few matings are sufficient for females to maximize their reproductive success. Contrary to …

A growing body of evidence has begun to reveal flaws in the traditional assumption of
female passivity and lack of discrimination after copulation has begun. William Eberhard has …

One hundred years after Darwin considered how sexual selection shapes the behavioral
and morphological characteristics of males for acquiring mates, Parker realized that sexual …

Publisher Summary This chapter reviews the current knowledge of variation in sperm
morphology over several levels of biological organization: variation within males (both within …
