Abstract A primary mission of Animal Resources Divisions at National Primate Research Centers (NPRC) is to maintain the overall social health of Indian-origin rhesus macaques (Macaca mulatta) living in large multi-generational breeding groups in order to ensure the availability of high-quality research subjects for NIH-funded research. The social dynamics of these breeding groups, however, are complex and disturbances in their dominance hierarchy and kinship structures can lead to increased aggression and fighting that may result in significant wounding. Thus, a common challenge in their management is the utilization of effective social heath surveillance methodology to identify groups at risk for social instability before the onset of significant fighting. These captive groups are routinely monitored for changes in dominance ranks and rates of trauma to detect social instability at the family- and group-level; however, the precise timing of severe outbreaks of aggression is largely considered unpredictable. Further, the frequency of interactions that define dominance and affiliative relationships in these groups are sparse; thus, the gathering of enough behavioral data to unequivocally detect social instability is time- consuming. We recently published a report that indicated automated feeding data can provide critical real-time data and assist management with monitoring social stability in rhesus macaque breeding groups, by possibly predicting the timing of intense aggression. The purpose of this proposal is to expand upon these observations by establishing data-driven models that help management identify groups at risk for social instability. Because automated feeding data include precise timestamps and the order in which animals feed, network analyses can be used to construct Feeding Interaction Networks (FINs), allowing us to examine patterns of temporal proximity feeding among kin and non-kin. Because reproductive status also influences food intake in female monkeys, we will study six outdoor breeding groups at the Yerkes NPRC across the breeding and birthing seasons, and integrate social and reproductive data, with the overarching aim to develop comprehensive data-driven FIN models that will enhance colony management practices of NIH-supported rhesus macaque breeding colonies. Aim 1 will characterize the community structures within static FINs of rhesus macaque breeding groups, varying in size and composition. Aim 2 will determine whether the directionality and strength of connections between adult females within a static FIN can be used to predict patterns of affiliative and dominance relationships among kin and non-kin. Aim 3 will quantify and model the temporal changes of community structures within dynamic FINs of rhesus macaque groups across the breeding and birthing season with respect to female reproductive phase. Finally, Aim 4 will detect changes in the community structures of dynamic FINs, not associated with reproductive seasonality, that are precursor to increased aggression and other signs of social instability. These FIN models will be used to supplement behavioral and trauma data, allowing management to identify groups at risk for social instability and develop strategies to intervene prior to the escalation of additional aggression.

抽象的 国家灵长类研究中心 (NPRC) 动物资源部门的主要任务是维持 生活在大型多代群体中的印度原产恒河猴（Macaca mulatta）的整体社会健康状况 育种小组，以确保为 NIH 资助的研究提供高质量的研究对象。 然而，这些繁殖群体的社会动态很复杂，并且扰乱了它们的统治地位 等级制度和亲属结构可能导致攻击性和战斗的增加，从而可能导致严重的后果。 伤人。因此，管理中的一个共同挑战是利用有效的社会健康监测 在重大战斗爆发之前识别面临社会不稳定风险的群体的方法。这些俘虏 定期监测群体的统治等级和创伤率的变化，以发现社会不稳定的情况 家庭和团体层面；然而，在很大程度上考虑了严重侵略爆发的确切时间 不可预测的。此外，定义这些领域中的主导地位和隶属关系的互动频率 群体稀疏；因此，收集足够的行为数据来明确地检测社会不稳定是需要时间的。 消耗。我们最近发布了一份报告，表明自动喂养数据可以提供关键的实时数据 数据并协助管理人员监测恒河猴繁殖群体的社会稳定性，可能通过 预测强烈攻击的时间。该提案的目的是扩展这些观察结果 通过建立数据驱动的模型来帮助管理层识别面临社会不稳定风险的群体。因为 自动喂食数据包括精确的时间戳和动物喂食的顺序，网络分析可以 用于构建喂养交互网络（FIN），使我们能够检查时间邻近的模式 亲属和非亲属之间的喂养。由于生殖状况也会影响雌性猴子的食物摄入量，我们 将研究 Yerkes NPRC 的六个户外繁殖群体的繁殖和分娩季节，以及 整合社会和生殖数据，总体目标是开发全面的数据驱动的 FIN 模型将增强 NIH 支持的恒河猴繁殖群体的群体管理实践。 目标 1 将描述恒河猴​​繁殖群体静态 FIN 内的群落结构特征，不同 在大小和组成上。目标 2 将确定之间的联系的方向性和强度 静态 FIN 内的成年女性可用于预测之间的隶属关系和支配关系模式 亲属和非亲属。目标 3 将量化和模拟动态范围内群落结构的时间变化 恒河猴群体在繁殖和分娩季节与雌性生殖的 FIN 阶段。最后，目标 4 将检测动态 FIN 的社区结构的变化，与 生殖季节性，这是攻击性增加和其他社会不稳定迹象的先兆。这些 FIN 模型将用于补充行为和创伤数据，使管理层能够识别群体 社会不稳定的风险，并在进一步的侵略升级之前制定干预战略。
