Study on cultural behavior of wild chimpanzees and bonobos : comparison of behavioral repertoires.

半个世纪以来对野生黑猩猩的专门实地研究表明，在研究群体之间存在行为变异，并且存在世代遗传。作者一直在进行野生倭黑猩猩的实地研究，在万巴，D。R.刚果和黑猩猩在Kalinzu森林，乌干达。作者描述了每个研究组的行为谱（一系列行为特征），并比较了黑猩猩和倭黑猩猩之间的行为特征。在黑猩猩群体中，笔者发现存在工具使用行为，如蚂蚁蘸食行为、用棍棒采集蜂蜜等。此外，作者还比较了这两个物种的性行为。作者揭示了雌性黑猩猩在交配行为序列中是主动的，而雌性倭黑猩猩在交配行为序列中只是被动的。这些结果发表在Primates上。作者与其他黑猩猩和倭黑猩猩研究地点的研究人员合作，参与了这两个物种所有研究地点的行为谱的创建。

Half a century of dedicated field research on wild chimpanzees has revealed that there are variations of behaviors among study groups and there are inherited between generations. The author has been conducting a field research on wild bonobos at Wamba, D. R. Congo and chimpanzees at the Kalinzu Forest, Uganda. The author described the ethogram (a list of behavioral repertoires) for each study group and compared the behavioral repertoires between chimpanzees and bonobos. In the chimpanzee group, the author found that there are tool-using behaviors, such as ant-dipping behavior and collecting honey with sticks. Moreover, the author compared the sexual behavior of both species. The author revealed that female chimpanzees were active in copulation while female bonobos played only a passive role in the copulatory behavior sequences. These results were published in Primates. The author cooperated with researchers from other study sites of chimpanzees and bonobos and took part in creating the ethogram which covers all the study site of both species.
