Social bonds and prosocial behaviors are fundamental aspects of many primate groups, including humans, yet the evolutionary roots and physiological underpinnings of these behaviors are poorly understood. This project will use hormonal, energetic, and behavioral data for two non-human primate species to better understand prosocial behaviors and male cooperation in primates. The study is unique in that it specifically will examine the potential physiological mechanisms that are associated with positive male-male social interactions within groups and with collective male aggression between groups. The findings will contribute to a broader understanding of the role of cooperation in primate evolution. This project will expand the PI's long-term commitment to international collaborations and educating STEM students and researchers. The field component involves training assistants in methods for behavior, ecology, and conservation research, while the laboratory component of this study will provide opportunities for University of Texas undergraduate and graduate students to receive training in modern molecular techniques. Through public outreach and conservation education by the PI and senior research personnel in both the US and abroad, the project will also support global primate and habitat conservation efforts.This project requests funds for a two-year study to characterize the physiological correlates of male social relationships among spider monkeys (Ateles belzebuth) and woolly monkeys (Lagothrix poeppiggi) in Yasuní National Park, Ecuador. The investigators will combine hormonal analyses with field observations, to 1) characterize interspecific and interindividual variation in testosterone (T) and glucocorticoids (GCs), and behavioral responses to both intra- and intergroup aggression, and 2) examine how this variation is influenced by the strength of intragroup social bonds and the intensity of between-group competition. Both spider and woolly monkeys are characterized by high rates of male-male affiliation and low rates of male-male aggression within groups. However, patterns of aggression between groups differ between these two species: boundary patrols and aggressive encounters between males from different groups of spider monkeys are among the most dramatic examples of collective aggression seen in non-human primates, paralleled only by the intergroup "warfare" seen in some populations of chimpanzees, while encounters between woolly monkey groups are frequently more tolerant. Thus this study will begin to untangle how the behavioral expression of similar physiological responses may be affected differently by individual versus group-level competition.

社会关系和亲社会行为是包括人类在内的许多灵长类群体的基本方面，但这些行为的进化根源和生理基础却鲜为人知。这个项目将使用两个非人类灵长类物种的荷尔蒙、能量和行为数据，以更好地了解灵长类动物中的亲社会行为和雄性合作。这项研究的独特之处在于，它将专门研究与群体内积极的男性社会互动和群体之间的男性集体攻击有关的潜在生理机制。这些发现将有助于更广泛地理解合作在灵长类进化中的作用。该项目将扩大国际和平协会对国际合作以及教育STEM学生和研究人员的长期承诺。现场部分包括对助理进行行为、生态学和保护研究方法的培训，而这项研究的实验室部分将为德克萨斯大学的本科生和研究生提供接受现代分子技术培训的机会。通过公共宣传和美国国内外高级研究人员的保护教育，该项目还将支持全球灵长类动物和栖息地保护工作。该项目要求为一项为期两年的研究提供资金，以表征厄瓜多尔亚苏尼国家公园蜘蛛猴(Ateles Belzebuth)和绒猴(Lagothrix Poepiggi)雄性社会关系的生理相关性。研究人员将把激素分析与实地观察相结合，以1)表征睾酮(T)和糖皮质激素(GC)的种间和个体间差异，以及对组内和组间攻击的行为反应，以及2)检查组内社会纽带的强度和组间竞争的强度如何影响这种变化。蜘蛛猴和绒毛猴的特征都是雄雄从属比率高，而群体内雄性攻击率低。然而，这两个物种群体之间的攻击模式不同：来自不同群体的蜘蛛猴的雄性之间的边界巡逻和攻击性接触是在非人类灵长类动物中看到的最戏剧性的集体攻击例子，只有在一些黑猩猩群体中看到的群体间的战争才能与之相提并论，而绒毛猴子群体之间的接触往往更宽容。因此，这项研究将开始解开相似生理反应的行为表达如何受到个体和群体层面竞争的不同影响的问题。
