Blue monkeys live in groups with a single adult male for most of the year, although other males may join the group during the mating season, even 'moving in' for several months. By measuring paternity in two blue monkey groups in a Kenyan rain forest, this project will assess whether long-term resident males and temporary intruders are equally successful at siring offspring in the group. We will thus test an assumption which underlies theories that explain different social systems, namely that males live in groups to maximize access to females and thus to increase their reproductive success. Reproductive behavior of males and females will be monitored in detail during the breeding season by teams of observers. We will relate patterns of male-male competition (chases and fights) and female mate preferences to offspring paternity. We can then assess whether male dominance correlates with increased reproductive output, and whether female mate preferences influence paternity. Our results will not only provide information on one species with an unexpectedly dynamic social system, but also comparative data from a little-studied primate radiation that can be used in testing and developing theories applicable to other primates and animals.

蓝猴一年中的大部分时间都与一只成年雄性生活在一起，尽管其他雄性可能会在交配季节加入这个群体，甚至“搬进来”几个月。 通过测量肯尼亚雨林中两个蓝猴群的亲子关系，该项目将评估长期居住的雄性和临时入侵者是否同样成功地在群体中繁衍后代。 因此，我们将测试一个假设，它是解释不同社会制度的理论的基础，即男性生活在群体中，以最大限度地接近女性，从而提高他们的繁殖成功率。 在繁殖季节，观察员小组将详细监测雄性和雌性的生殖行为。 我们将把雄性与雄性之间的竞争模式（追逐和打斗）和雌性对配偶的偏好与后代的父权联系起来。 然后，我们可以评估男性主导地位是否与生殖输出增加相关，以及女性配偶偏好是否影响父权。 我们的研究结果不仅将提供一个物种的信息，一个出乎意料的动态社会系统，但也比较数据，从一个很少研究的灵长类动物辐射，可用于测试和发展适用于其他灵长类动物和动物的理论。
