In non-human primates, groups often engage in between group aggression. Despite the integral role these social interactions play in models predicting and explaining primate behavior, our knowledge of why individuals choose to engage in this risky behavior remains somewhat limited. In general, aggression between groups is attributed to defense of resources or defense of mates and infants. This project will investigate the factors underlying aggression during between-group encounters in a territorial South American primate: the white-faced saki monkey. This arboreal primate occupies small home ranges which are actively defended from neighboring groups along home range boundaries. In order to comprehensively test the function of this aggression, this project will gather data on between-group encounters among white-faced saki groups at Brownsberg Nature Park, Suriname. Variation in aggression and individual participation in these interactions will be assessed in terms of dependence upon food abundance, female reproductive state, and within group social bonds. Such data will provide valuable information on a little known primate species as well as serve as a case study to help develop models of primate social behavior. The broader impacts of this study include collaboration with the National Herbarium of Suriname and the training of a Surinamese student. This project will also integrate lines of evidence from often distinct aspects of primatology (feeding behavior, social behavior, and endocrine analysis) in order to comprehensively examine a behavioral trait. This doctoral dissertation research project will contribute to the academic training of a female graduate student.

在非人类灵长类动物中，群体之间经常进行群体攻击。尽管这些社会互动在预测和解释灵长类动物行为的模型中扮演着不可或缺的角色，但我们对个体为什么选择参与这种危险行为的了解仍然有限。一般来说，群体之间的攻击归因于资源的防御或配偶和婴儿的防御。 这个项目将调查在南美洲灵长类动物的领土：白脸萨基猴群体间遭遇的潜在侵略的因素。这种树栖灵长类动物占据着小的家域，这些家域积极地防御着沿着家域边界的邻近群体。为了全面测试这种攻击性的功能，本项目将收集苏里南布朗斯堡自然公园白脸萨基群体之间群体间遭遇的数据。在侵略和个人参与这些相互作用的变化将进行评估的依赖食物丰富，女性生殖状态，并在组内的社会纽带。 这些数据将提供关于一个鲜为人知的灵长类物种的有价值的信息，并作为一个案例研究，以帮助开发灵长类动物社会行为的模型。 这项研究的更广泛影响包括与苏里南国家植物标本馆的合作和对苏里南学生的培训。 该项目还将整合来自灵长类动物学（摄食行为，社会行为和内分泌分析）的不同方面的证据，以全面检查行为特征。本博士论文研究项目将有助于对一名女研究生进行学术培训。
