In some species, males display traits that may provide information about their quality to potential female mates, and variation in those traits drives females to choose or avoid those males as mates. This study examines whether seasonal fat increase in wild nonhuman primate males is related to their reproductive success. This project advances knowledge about the evolution of physiology and sociality in our nonhuman primate relatives. This project also fosters the participation of women and underrepresented minorities in STEM by providing mentored research to historically underrepresented groups such as first-generation students, low-income students, and students of color at Hispanic Serving Institutions. Undergraduate students work to collect and analyze field data and assist in the dissemination of the project findings. This project provides mentored research and field-based experiences, unique training opportunities for these students, and supports conservation of wild primates and their habitats through activities at the local level through educational outreach.This work provides new insight into sexual selection by examining the relationships among signals of mate quality, a measurement of genetic quality, and mate choice in a wild nonhuman primate. The research team integrate behavioral data collected in the field and molecular methods used in the laboratory to examine the reproductive consequences of individual variation in seasonal male fat increase, and test whether this variation is related to variation in Major Histocompatibility Complex (MHC) genes. Specifically, this project determines parent-offspring relationships and uses behavioral and genetic data to assess whether male fattening is a product of female choice, and thus an honest indicator of one marker of genetic quality, or a product of male-male competition and therefore decoupled from male MHC diversity.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.

在某些物种中，男性表现出可能为潜在女同伴提供有关其质量的信息，这些特征的变化驱动女性选择或避免那些男性作为伴侣。这项研究研究了野生非人类灵长类动物雄性的季节性脂肪是否与其生殖成功有关。该项目在非人类灵长类动物的亲戚中促进了有关生理和社会性演变的知识。该项目还通过向历史上代表性不足的群体（例如第一代学生，低收入学生和有色人种的学生）提供了在西班牙裔服务机构等历史不足的群体（例如，妇女和代表性少的少数族裔参与STEM）的参与。本科生致力于收集和分析现场数据并协助传播项目发现。该项目通过教育宣传通过在地方一级的活动来提供指导的研究和基于现场的经验，为这些学生提供独特的培训机会，并通过教育宣传来保护野生灵长类动物及其栖息地。这项工作通过检查性选择的新见解，通过检查性选择的新见解。伴侣质量的信号，遗传质量的测量以及野生非人类灵长类动物中的伴侣选择。研究团队整合了在实验室中收集的行为数据，并在实验室中使用的分子方法研究了季节性男性脂肪增加的个体变异的生殖后果，并测试这种变异是否与主要组织相容性复合物（MHC）基因的变化有关。具体而言，该项目确定父母的春季关系，并使用行为和遗传数据来评估男性肥大是女性选择的产物，因此是一种遗传质量标记的诚实指标，还是男性男性竞争的产物，因此是脱钩的该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响评论标准来评估值得支持的。
