This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Though humans are remarkable in terms of cooperation, there are other social mammals including some non-human primates that regularly cooperate with non-kin and at the group-level. In some species, individuals are highly collaborative within their group, while relations are hostile between groups, suggesting that competition between groups may shape the social nature of species. This doctoral dissertation research advances knowledge about evolutionary and physiological drivers of cooperation within groups in non-human primates and examines the importance of competition as a potential driver of group cohesion. The project advances knowledge about animal social behavior and provides comparative data for understanding how group membership and intergroup conflict may have shaped patterns of cooperation in humans. The project provides scientific training to students through mentorship and field experience opportunities, and aids in conservation efforts by engaging with conservation organizations and local communities. This project involves the non-invasive collection and analysis of behavioral and hormonal data to investigate the theory of parochial altruism in which conflict between groups is crucial for intensifying cooperation within groups. The researchers examine whether intergroup conflict influences within-group sociality in a highly intelligent and cooperative non-human primate species that displays hostile between-group relations. The project examines the evolutionary roots and biological underpinnings of parochial altruism by a) determining whether intergroup conflict impacts within-group socio-positive behaviors, b) investigating whether, as in humans and chimpanzees, oxytocin underpins participation in cooperative group ventures such as territory defense, and c) assessing at the group level whether there is a relationship between measures of social cohesion and success in intergroup interactions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项是根据2021年《美国救援计划法》（公法117-2）全部或部分资助的。尽管人类在合作方面是显着的，但还有其他社会哺乳动物，包括一些非人类灵长类动物，这些灵长类动物经常与非亲属和小组级合作。在某些物种中，个体在群体中是高度协作的，而群体之间的关系是敌对的，这表明群体之间的竞争可能会影响物种的社会性质。这项博士学位论文研究促进了有关非人类灵长类动物团体内部合作的进化和生理驱动力的知识，并研究了竞争作为群体凝聚力的潜在驱动力的重要性。该项目提高了有关动物社会行为的知识，并提供了比较数据，以了解小组成员资格和群体间冲突如何塑造了人类合作的模式。该项目通过指导和实地经验机会为学生提供科学培训，并通过与保护组织和当地社区互动来帮助保护工作。该项目涉及对行为和荷尔蒙数据的非侵入性收集和分析，以研究狭och的利他主义理论，在这种理论中，群体之间的冲突对于加强群体内的合作至关重要。研究人员检查了群体间冲突是否影响了一种表现出敌对的群体间关系的高度聪明和合作的非人类灵长类动物的组内社会性。 The project examines the evolutionary roots and biological underpinnings of parochial altruism by a) determining whether intergroup conflict impacts within-group socio-positive behaviors, b) investigating whether, as in humans and chimpanzees, oxytocin underpins participation in cooperative group ventures such as territory defense, and c) assessing at the group level whether there is a relationship between measures of social cohesion and success in intergroup互动。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来评估值得支持。
