Spider monkey are one of a handful of mammalian species that live in social groups that display "fission-fusion" dynamics, where group members break into small parties of variable and changing composition for daily foraging and travel. An individual animal's decisions about when to associate with other group members and with whom to associate are thought to be influenced by a number of socioecological factors, including the availability of food resources and the risk of predation in the habitat, the animal's own reproductive status and that of other group members, and the animal's genetic relatedness to other individuals in its social group. This project will investigate the relative influence of these different classes of variables on the grouping patterns of white-bellied spider monkeys using a combination of observational data collected in Yasuni National Park, Ecuador as well as genetic and hormonal data on gleaned from noninvasively collected samples. The study will contribute to further understanding of the principles underlying the evolution of grouping patterns in primates and other mammals. Assuming that similar general biological principles apply, then an elucidation of the factors influencing flexible grouping patterns in spider monkeys will help us identify the social and ecological conditions that are shared amongst different groups of mammals that live in fission-fusion systems (e.g., dolphins, elephants, hyenas). Additionally, the study will contribute to an understanding of the evolution of human social behavior as spider monkeys are behaviorally and ecologically convergent with chimpanzees, the nonhuman primate which currently provides the closest living analogs for the behavior of the earliest hominins. Spider monkeys and chimpanzees share a variety of characteristics of social organization, including male philopatry, female dispersal, and strong male-male associations flexible subgrouping associations, in addition to their convergent flexible social associations.This will contribute to an ongoing long-term investigation on the comparative behavioral biology of sympatric Amazonian primates at the Tiputini Biodiversity Station in Ecuador and assist in efforts at protecting forested areas in the Ecuadorian Amazon. Additionally, it will help to strengthen the collaborations between local researchers in Ecuador and Colombia and institutions in the United States. The extension of this project (Proyecto Primates Ecuador) into other field sites in the neotropics has recently started through the launch of Proyecto Primates Colombia. In both Ecuador and Colombia, Proyecto Primates has provided the opportunity to multiple students and young professionals to build on their field experience and gain expertise in the behavioral and ecological sciences.

蜘蛛猴是生活在“裂变融合”动力学的社会群体中的少数哺乳动物物种之一，其中小组成员分为可变的小政党，而不断变化的构图进行日常觅食和旅行。一个动物关于何时与其他群体交往的决定，并被认为是受到许多社会生态因素的影响，包括粮食资源的可用性和栖息地中的捕食风险，动物自身的生殖地位以及其他群体成员的生殖状况以及该动物与社会群体中其他人的遗传相关性。该项目将使用在伊松国家公园，厄瓜多尔（厄瓜多尔）中收集的观察数据组合以及对从非侵入性收集的样品中收集的收集的样品中收集的观察数据的组合，研究这些不同类别变量对白腹蜘蛛猴的分组模式的相对影响。该研究将有助于进一步理解灵长类动物和其他哺乳动物分组模式演变的原理。假设适用类似的一般生物学原理，那么阐明影响蜘蛛猴中柔性分组模式的因素将有助于我们确定生活在裂变融合系统中的不同哺乳动物组中共享的社会和生态条件（例如，海豚，大象，大象，鬣狗）。此外，这项研究将有助于理解人类社会行为的演变，因为蜘蛛猴在行为和生态上与黑猩猩的融合，这是非人类的灵长类动物，目前为最早的人类的行为提供了最接近的生活类似物。蜘蛛猴和黑猩猩都具有社会组织的各种特征厄瓜多尔亚马逊地区的森林地区。此外，这将有助于加强厄瓜多尔与哥伦比亚的当地研究人员与美国的机构之间的合作。该项目（Proyecto Primates厄瓜多尔）的扩展到新型新型现场的其他现场站点，最近通过哥伦比亚Proyecto Primates的启动开始。在厄瓜多尔和哥伦比亚，Proyecto灵长类动物为多位学生和年轻专业人员提供了建立自己的现场经验并获得行为和生态科学专业知识的机会。
