Social Contact and Reproductive Cycles in Wild Chimpanzees (Pan Troglodytes)

拟议的项目将分析原始数据 在1975年至1989年期间系统收集的关于自由放养的 坦桑尼亚贡贝国家公园的黑猩猩。 数据 记录存放在达累斯萨拉姆，必须在那里进行审查。 其目的是检验在以下研究中产生的假设： 圈养的动物， 社会接触和野生动物生殖器肿胀的模式 雌性黑猩猩 众所周知，人类女性生活在一起， 来同步她们的月经周期（宿舍效应）， 表明社会接触是 调节同步。 实验室实验表明， 黑猩猩发情期肿胀的同步发生也是 通过社会接触来调节。 该项目将决定是否 在自然条件下也可以证明类似的同步性， 从而增加了我们的知识的机制所涉及的 黑猩猩的生殖生命周期

The proposed project will analyze original data systematically collected between 1975 and 1989 on free-ranging chimpanzees in the Gombe National Park, Tanzania. The data records are housed in Dar es Salaam and must be reviewed there. The purpose is to test the hypothesis, generated in studies of captive animals, that there is a correlation between the degree of social contact and the pattern of genital swelling in wild female chimpanzees. It is well known that human females who live together tend to synchronize their menstrual cycles (the dormitory effect), suggesting that social contact is the significant factor regulating synchrony. Laboratory experiments have indicated that synchronous onset of estrous swelling in chimpanzees is also mediated by social contact. This project will determine whether similar synchrony can be demonstrated under natural conditions, thus adding to our knowledge of the mechanisms involved in the reproductive life cycles of chimpanzees.
