This study focuses on the interacting male and female reproductive strategies of hamadryas baboons, a nonhuman primate with a unique and complex multilevel social system in which males transfer females between social units. The hamadryas social system may have more parallels to humans of any nonhuman primate, thus this study has great potential to enhance our understanding of human social evolution. In addition, this study will provide empirical data from wild animals to improve captive animal management in zoological parks in the USA and may also inform human obstetrics and gynecology. The project will support researcher training, conservation awareness, prevention of human-wildlife conflict, and improvement of snake-bite treatment options in areas surrounding the research site. Hamadryas takeovers involve substantial male aggression; they lead to delayed reproduction in females as well as higher rates of infanticide and infant mortality in general. Using observational behavioral data and endocrine measures from fecal hormone samples collected from wild hamadryas baboon females at Filoha, Ethiopia, the investigators will study female strategies that may function to counteract this coercion and its implications. For example, lactating females may display false signals of sexual receptivity to males post-takeover, thereby preventing the loss of a dependent infant. In addition, pregnant females may use a strategy of pregnancy termination post-takeover, thus mitigating the eventual loss of investment in offspring. This project would be the first to provide hormonal evidence of deceptive swellings in any primate species, as well as the first to provide hormonal evidence for pregnancy failure in hamadryas baboons. More broadly, the results of this study will fill gaps in the theoretical scientific literature on sexual selection, sexual conflict, and the co-evolution of male and female reproductive strategies.

本研究的重点是相互作用的男性和女性的生殖策略的hamadryas狒狒，非人灵长类动物具有独特而复杂的多层次的社会系统中，男性之间的社会单位转移女性。 在非人类灵长类动物中，蛤蟆的社会系统可能与人类有更多的相似之处，因此这项研究对增进我们对人类社会进化的理解具有巨大的潜力。此外，这项研究将提供来自野生动物的经验数据，以改善美国动物园的圈养动物管理，也可能为人类妇产科提供信息。该项目将支持研究人员培训，保护意识，防止人类与野生动物冲突，并改善研究地点周围地区的蛇咬伤治疗方案。Hamadryas接管涉及大量的男性侵略;它们导致女性推迟生育以及更高的死亡率和婴儿死亡率。使用从埃塞俄比亚Filoha的野生hamadryas狒狒雌性收集的粪便激素样本中观察到的行为数据和内分泌措施，研究人员将研究可能起作用以抵消这种胁迫及其影响的雌性策略。例如，哺乳期的雌性可能会在接管后向雄性显示性接受的错误信号，从而防止失去依赖的婴儿。此外，怀孕的女性可能会使用一种策略，妊娠终止后接管，从而减轻投资后代的最终损失。该项目将是第一个提供任何灵长类动物中欺骗性流产的激素证据，也是第一个提供hamadryas狒狒怀孕失败的激素证据。 更广泛地说，这项研究的结果将填补性选择，性冲突和男性和女性生殖策略的共同进化的理论科学文献中的空白。
