The ability to establish, develop, and maintain social relationships is important in many species, including humans. There are positive effects of social bonds on health, mortality, and reproduction. In this project, the researchers will examine behavioral, demographic and genetic factors that may contribute to the ability of an individual to establish successful social relationships. Focusing on a non-human primate model in which both father and mother provide care to their young, the researchers will study interactions between reproducing pair-bonded adults and solitary non-reproducing ones. This research will contribute to a better understanding of social relationships, including mating and parenting relationships, in pair-living, monogamous groups. The team will train nine undergraduate students, two Ph.D. students and one postdoctoral researcher from groups underrepresented in STEM fields. International collaborations with researchers in Argentina will be strengthened, and the investigators will expand efforts to foster the development of the biological anthropology discipline in Latin America. At the national level, outreach activities will include working with programs involving underrepresented minority high-school and undergraduate students in research (STARS program at the Yale Peabody Museum) and creating a public series of presentations based on their work for topics regularly covered in animal behavior and biological anthropology courses. This research project occurs within the Owl Monkey Project of Argentina, an international research program to advance knowledge and theory about the evolution of pair-bonding, monogamy, and paternal care. In this new study, a team of researchers, undergraduate students, graduate students and postdocs will collect demographic and genetic data from individuals in 60 groups of owl monkeys. The investigators will study solitary individuals who have left their natal group but have not yet pair-bonded, as well as pair-bonded adults. The solitary individuals need to enter a group to reproduce, which generates intense competition between solitary and pair-bonded adults. Data collected as part of this project will be used to evaluate how competition between solitary floaters and pair-bonded adults influences infant development and survival, natal dispersal patterns, pair-bond formation and stability, and mating patterns. In addition, because this primate species shows very little physical difference between males and females, but intense competition in both sexes, these data will be valuable for understanding the evolution of sex-specific morphologies and behaviors. The project will therefore make theoretical and empirical contributions to a number of concepts that are central to biological anthropology and evolutionary biology.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.

在包括人类在内的许多物种中，建立，发展和维持社会关系的能力很重要。社会纽带对健康，死亡率和繁殖有积极影响。在这个项目中，研究人员将研究可能有助于个人建立成功社会关系的能力的行为，人口和遗传因素。研究人员专注于非人类的灵长类动物模型，在该模型中，父亲和母亲都为年轻人提供照顾，研究人员将研究复制成年人和孤立的非复制成年人之间的相互作用。这项研究将有助于更好地理解社会关系，包括成对的一夫一妻制群体，包括交配和育儿关系。团队将培训九名本科生，两位博士学位。来自STEM领域中代表性不足的小组的学生和一名博士后研究人员。将加强与阿根廷研究人员的国际合作，研究人员将扩大努力，以促进拉丁美洲生物人类学学科的发展。在国家一级，外展活动将包括与涉及不足的少数民族高中和本科生研究的计划（耶鲁大学皮博迪博物馆的明星计划）以及基于其定期涵盖动物行为和生物拟人类学课程的主题的公开演讲的公开演讲。该研究项目发生在阿根廷的猫头鹰猴项目中，这是一项国际研究计划，旨在推进有关成对结构，一夫一妻制和父亲护理的发展的知识和理论。在这项新研究中，一组研究人员，本科生，研究生和博士学位将从60组猫头鹰猴子中的个人那里收集人口统计学和遗传数据。研究人员将研究离开其出生群体但尚未成对的孤独的个体以及成对的成年人。孤独的个体需要进入一个小组来繁殖，这会在孤立的成年人和成对的成年人之间产生激烈的竞争。作为该项目的一部分收集的数据将用于评估孤立浮子和成对成年人之间的竞争如何影响婴儿的发育和生存，出生的分散模式，成对的形成和稳定性以及交配模式。此外，由于这种灵长类动物在男性和女性之间显示出很少的身体差异，但是在两性中的激烈竞争，这些数据对于理解性别特定的形态和行为的演变而言是有价值的。因此，该项目将对许多对生物人类学和进化生物学至关重要的概念做出理论和经验贡献。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛影响的审查标准通过评估来通过评估来支持的。
