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.

我们不清楚地了解群体生活的利益和成本通常对灵长类动物来说是什么。 性别差异可能起作用。 在大多数灵长类动物中，雌性仍然留在其终生中，而男性在成熟之前分散。 鉴于这种女性束缚系统的流行，男性团体成员对女性有什么好处和成本？ 在灵长类动物物种之间和内部的男性数量有所不同，但我们不知道为什么。 该论文项目将在哥斯达黎加的这种女性束缚的灵长类动物社会体系中研究一些短期的福利和社会成本。 群体生活提出的主要好处是捕食者保护和改善资源的获取，而主要成本则是集群内部竞争。 该研究将比较与男性和女性的捕食者防御，资源防御和资源竞争相关的特定行为。 发现将与灵长类动物社会性的进化解释有关。 该项目的信息将增强我们对社会性及其在灵长类动物中的适应性意义的理解。 该项目还将培训一位非常有前途的年轻科学家。
