We do not clearly understand what the benefits and costs of group living are for primates generally. Sex differences may play a role. In most primate species, females remain in their natal groups for life, whereas males disperse prior to maturity. Given the prevalence of this female-bonded system, what are the benefits and costs of male group members for females? The number of males per group varies between and within primate species, but we do not know why. This dissertation project will examine some short-term benefits and costs of sociality in such a female-bonded primate social system in Costa Rica. The main benefits proposed for group living are predator protection and improved access to resources, while tha main cost is presumed to be within-group competition. The study will compare specific behaviors associated with predator defense, resource defense, and resource competition in males and females. Findings will be related to evolutionary explanations of primate sociality. Information from the project will enhance our understanding of sociality and its adaptive significance in primates. The project will also train a very promising young scientist.

我们并不清楚群体生活对灵长类动物的好处和成本。 性别差异可能发挥一定作用。 在大多数灵长类动物中，雌性终生留在出生时的群体中，而雄性在成熟之前就分散了。 鉴于这种女性束缚制度的盛行，男性团体成员对女性的好处和成本是什么？ 每组雄性的数量在灵长类动物之间和内部有所不同，但我们不知道为什么。 本论文项目将研究哥斯达黎加这种雌性灵长类动物社会系统中社会性的一些短期效益和成本。 群居的主要好处是保护捕食者和改善资源获取，而主要成本被认为是群体内的竞争。 该研究将比较雄性和雌性与捕食者防御、资源防御和资源竞争相关的具体行为。 研究结果将与灵长类社会性的进化解释相关。 该项目的信息将增强我们对灵长类动物的社会性及其适应性意义的理解。 该项目还将培养一位非常有前途的年轻科学家。
