Recent genetic research on chimpanzees (Pan troglodytes verus) of the Tai forest, Ivory Coast reveals that half of the offspring in the study community were sired by males from another group. This is remarkable because females are thought to Remain primarily within their own territory, and extra- group males are rarely seen to mate with these females. These surprising results have challenged many of our prior expectations regarding chimpanzee reproductive success and suggest that females may have more influence on paternity than previously thought. The proposed 24 month study of chimpanzees in the Tai forest will directly address the extent to which females 1) express mate preference for particular males, 2) influence the outcome of sexual interactions, and 3) demonstrate greater influence on the outcome of sexual interactions during the time when they are most likely to conceive. By following females throughout the duration of their estrous cycles, this study will examine female reproductive behavior at various stages of estrous. It will elucidate factors that most influence a female's ability to affect the outcome of a sexual interaction, in light of the inherent conflicts between male and female mating strategies. Results from this study will contribute to our understanding of the genetic and behavioral reproductive patterns of chimpanzees in the wild, assist in elucidating the factors responsible for differential reproductive success in chimpanzees, and provide essential information for informed decision-making regarding the conservation and maintenance of the genetic diversity of this species.

最近对象牙海岸Tai森林黑猩猩（Pan troglodytes verus）的遗传研究表明，研究社区中一半的后代是由另一个群体的雄性所生。 这是值得注意的，因为雌性被认为主要呆在自己的领地内，很少看到群外的雄性与这些雌性交配。 这些令人惊讶的结果挑战了我们之前对黑猩猩繁殖成功的许多期望，并表明雌性对父权的影响可能比以前认为的要大。 拟议中的24个月的研究黑猩猩在泰森林将直接解决的程度，女性1）表达配偶偏好特定的男性，2）影响性互动的结果，和3）证明更大的影响力的结果，性互动的时间，当他们最有可能怀孕。 通过跟踪雌性动物的整个发情周期，本研究将研究雌性动物在发情的各个阶段的生殖行为。 它将阐明的因素，最影响女性的能力，影响性互动的结果，在男性和女性交配策略之间的固有冲突。 这项研究的结果将有助于我们了解野生黑猩猩的遗传和行为生殖模式，有助于阐明黑猩猩差异生殖成功的因素，并为保护和维护该物种的遗传多样性提供必要的信息。
