Alternative reproductive tactics

the long version

"Consistent variation in the reproductive behavior of males and females within a species is an evolutionary puzzle. How two forms of male can develop in one species, for example, and how such variation can be maintained in one population at the same time, offers a special opportunity to study the evolution and functional causes of phenotypic variation, which is a general problem in the field of evolutionary biology. By integrating both proximate (physiological) and primate (evolutionary) perspectives and by covering a great diversity of species, Alternative Reproductive Tactics addresses this exciting topic of longstanding interest, bringing together a multitude of information in an accessible form that is ideal for graduate students and researchers in evolutionary biology, behavior, and reproductive physiology."--Jacket.
