The long-term objective in this study is to develop a comprehensive picture of how behavior shapes population dynamics and individual life history outcomes in one population of wild mammals, the savanna baboons of the Amboseli basin in east Africa. The overall conceptual framework is concerned with how behavior affects survival and reproduction across the life time, as well as how behavior affects physiology and population genetics. Throughout their long-term work, the investigators have focused on a series of short-term goals that represent components of their long-term objective. With this LTREB project they overtly reach toward one longer-term goal. Specifically, they will follow the ongoing process of genetic admixture (hybridization) between a study population of primarily yellow baboons and neighboring populations of anubis (olive) baboons (a separate subspecies) in order to understand the way in which behavior impacts, and is in turn affected by hybridization. Their previous work has documented rather dramatic differences between hybrid and yellow baboons. This represents a unique opportunity to follow a natural process of population admixture over time, and to test hypotheses about its behavioral causes and consequences. This project is relevant to understanding speciation because of the role that hybridization can play in speciation. It is also relevant to understanding human evolution because of the close ecological parallels between baboons and humans, and the similarity between the baboon radiation in Africa and the evolutionary history of various human species. The proposed project will continue the investigators' long history of training American and Kenyan students, activities that are intimately connected with the research goals. Recent integration of research and education has focused on training for 13 post-doctoral fellows, 12 doctoral candidates, 5 Master's Degree students, 34 undergraduates, and 2 high school students. The investigators also actively collaborate with Kenyan scientists and are working with them on in-country capacity building.

本研究的长期目标是全面了解行为如何塑造一个野生哺乳动物种群（东非安博塞利盆地的稀树草原狒狒）的种群动态和个体生活史结果。整体概念框架关注行为如何影响整个生命周期的生存和繁殖，以及行为如何影响生理学和群体遗传学。 在他们的长期工作中，调查人员一直专注于一系列短期目标，这些目标代表了他们长期目标的组成部分。通过这个LTREB项目，他们公开地达到一个长期目标。具体来说，他们将遵循主要是黄色狒狒的研究群体和相邻的anubis（橄榄）狒狒（一个单独的亚种）群体之间的遗传混合（杂交）过程，以了解行为影响的方式，并反过来受到杂交的影响。他们之前的工作已经记录了杂交狒狒和黄色狒狒之间的巨大差异。这代表了一个独特的机会，随着时间的推移，人口混合的自然过程，并测试其行为的原因和后果的假设。由于杂交在物种形成中的作用，这个项目与理解物种形成有关。它也与理解人类进化有关，因为狒狒和人类之间的生态相似性，以及非洲狒狒辐射与各种人类物种进化历史之间的相似性。拟议的项目将延续调查人员培训美国和肯尼亚学生的悠久历史，这些活动与研究目标密切相关。最近的研究和教育的整合集中在培养13名博士后研究员，12名博士研究生，5名硕士研究生，34名本科生和2名高中生。调查人员还积极与肯尼亚科学家合作，并与他们合作进行国内能力建设。
