Dissertation Research: Testosterone, Aggression and Dominance in Wild Chimpanzees

黑猩猩在各种情况下都会表现出攻击性，但其根本原因往往不清楚。 这个项目将是第一个研究野生雄性黑猩猩的攻击性和统治性的激素方面。 这项研究将收集和分析荷尔蒙数据，以调查黑猩猩攻击的近因和根本原因。 除了黑猩猩，这项研究应该为理解人类的攻击性提供一个更广泛的比较框架，因为我们自己与黑猩猩的遗传亲和力非常接近。 这项研究将通过检测生活在乌干达基巴莱国家公园的黑猩猩个体的睾丸激素水平来进行。比较数据将从生活在坦桑尼亚国家公园贡贝的第二个黑猩猩社区收集。 黑猩猩社会行为模式的地点间差异还没有得到很好的理解，这项研究旨在帮助解决这些差异。

Chimpanzees behave aggressively in a variety of contexts, but the underlying causes are often unclear. This project will be the first to study hormonal aspects of aggression and dominance in wild male chimpanzees. The study will collect and analyze hormonal data in order to investigate both the proximate and ultimate causes of chimpanzee aggression. In addition to chimpanzees, this study should provide a broader comparative framework for understanding human aggression, due to our own very close genetic affinity to chimpanzees. The research will be carried by examining testosterone levels, collected using a completely non-invasive method, in individual chimpanzees living in Kibale National Park, Uganda. Comparative data will be collected from a second community of chimpanzees living in Gombe National Park, Tanzania. Intersite differences in patterns of chimpanzee social behavior are not well understood, and this study is designed to help resolve these differences.
