项目摘要

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.

社会纽带和亲社会行为是包括人类在内的许多灵长类动物群体的基本方面，但是这些行为的进化根源和身体基础知之甚少。该项目将使用两个非人类灵长类动物物种使用骑马，充满活力和行为数据，以更好地理解亲社会行为和私人的男性合作。这项研究的独特之处在于，它将特别研究与群体内的积极男性社会互动相关的潜在生理机制，以及群体之间的集体男性侵略性。这些发现将有助于更广泛地理解合作在私人进化中的作用。该项目将把PI的长期承诺扩展到国际合作，并教育STEM学生和研究人员。该领域组成部分涉及培训助手的行为，生态和保护研究方法，而本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机会接受现代分子技术培训。通过PI和国外的PI和高级研究人员的公共拓展和保护教育，该项目还将支持全球灵长类动物和栖息地保护工作。该项目要求进行两年的研究资金，以表征蜘蛛猴（Ateles belzebuth）（Ateles Belzebuth）和Woolly Monkeys和Woolly Monkeys（Lagothrixrix Poepoepepiggi）的身体社会关系的身体相关性。研究人员将将骑马分析与现场观测结合在一起，至1）表征睾丸激素（T）和糖皮质激素（GCS）（GCS）的种间和个体变化，以及对组内和组间侵略的行为反应，以及2）研究这种变异如何受到内部社交键和强度竞争的强度的影响。蜘蛛和羊毛猴子的特征是男性分支机构的高率和小组内男性侵略性的率低。然而，这两个物种之间不同的群体之间具有积极进取的模式：来自不同蜘蛛猴群的男性之间的侵略性相遇是在非人类隐私中看到的集体侵略性的最戏剧性的例子之一，仅与奇纳兹人的某些人群中的“战争”中的“战争”相似，而却是奇特的一些人，而羊毛猴子通常更容易容忍。这项研究将开始解开如何受个人竞争与群体级竞争的不同影响相似物理反应的行为表达。
