一个群体中成年雄性的数量是灵长类社会组织中变化最大的方面之一。这种变化的原因构成了灵长类动物学研究的长期焦点。1由于雄性的繁殖成功主要受到接近雌性的限制，2雄性之间的竞争应导致将竞争对手排除在雌性群体之外。4，5然而，许多灵长类物种与几个成年雄性一起生活。为了解释这种共享雄性群体成员身份的原因和后果，灵长类学家开始在生殖偏斜理论的框架内研究这一现象。这个博弈理论模型的主体是为了研究种群和物种之间以及种群和物种之间的生殖偏斜的变化，并解释稳定关联的前提条件，以及如何在其中分配生殖。6-9在这里，我们总结了这一理论的主要方面，审查其应用研究的男性生殖策略，并确定陷阱与使用这种方法。
The number of adult males in a group is one of the most variable aspects of primate social organization. The causes for this variation have constituted a longstanding focus in primatological research. 1 As a male’s reproductive success is mainly limited by access to females, 2 competition among males should result in the exclusion of rivals from groups of females. 4,5 However, a great number of primate species live in groups with several adult males. To explain the causes and consequences of this shared male group membership, primatolo-gists have begun to examine the phenomenon within the framework of reproductive skew theory. This body of game theoretical models was developed to examine variation in reproductive skew within and across populations and species and to explain the preconditions for stable associations, as well as how reproduction should be distributed therein. 6–9 Here we summarize the main aspects of this theory, review its application to studies of male reproductive strategies, and identify pitfalls associated with using this approach.
