Animals need different combinations of nutrients to survive and reproduce, but for many species, we do not know how survival and reproduction is affected by nutrient intake across a lifetime. It is difficult to study this relationship in humans because of our long lifespans, which may encompass many different periods of food availability that might not be known. This Doctoral Dissertation Research project assesses how lifetime nutrient intake and diet influence survival and reproduction in a wild primate, including during an extreme drought, which had major impacts survival. Extreme climatic events are increasing in severity and frequency world-wide, and the results of this project can therefore enhance our understanding of how diet and nutrition interact with survival during such events. This project serves as the doctoral dissertation for a student in biological anthropology and nutritional ecology, trains two early career female scientists, contributes to the conservation of a wild primate and its endangered habitat, and provides early education opportunities for local school children. This project focuses on three objectives: 1) Identify the nutritional goals of female white-faced capuchins (Cebus capucinus) across the life course, 2) Identify the best possible diets of female white-faced capuchins across the life course, and 3) Examine how poor nutrient and dietary intake relates to survival and reproduction, especially during an extreme drought that occurred between 2014 - 2016. To address these objectives, researchers collect feeding data on capuchins to determine what individuals eat. Researchers also collect food samples to determine nutrients that capuchins consume. Lastly, researchers use a long-term database (33+ years) to relate intake to survival and reproduction, especially during the drought.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.

动物需要不同的养分组合来生存和繁殖，但是对于许多物种，我们不知道生存和繁殖如何受到一生中养分摄入的影响。由于我们的寿命很长，因此很难在人类中研究这种关系，这可能包含许多可能未知的食物可用性时期。该博士学位论文研究项目评估了终生的营养摄入量和饮食如何影响野生灵长类动物的生存和繁殖，包括在极端干旱期间，这产生了重大影响。极端气候事件在全球范围内的严重性和频率都在增加，因此该项目的结果可以增强我们对此类事件中饮食和营养如何与生存相互作用的理解。该项目是生物人类学和营养生态学学生的博士学位论文，培训了两名早期职业女性科学家，为野生灵长类动物及其濒危栖息地的保护做出了贡献，并为当地的小学生提供了早期的教育机会。该项目侧重于三个目标：1）确定整个生活过程中女性白面胶囊（Cebus capucinus）的营养目标，2）确定女性白脸尾胶蛋白的最佳饮食在整个生活过程中，以及3）3）研究较差的营养和饮食摄入量与在2014年的极端饮食中的养分和饮食摄入量有关，尤其是在2014年群体之间进行的研究，以下是在2016年群体之间进行的研究。确定个人吃什么。研究人员还收集食物样品，以确定卷尾胶食品消耗的营养。最后，研究人员使用长期数据库（33年以上）将摄入量与生存和繁殖联系起来，尤其是在干旱期间。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的影响来通过评估来获得支持的审查标准。
