Adaptive strategy and evolutionary trend of pygmy chimpanzees (Pan paniscus)

本项目旨在分析1984年至1988.1年间在扎伊尔万巴进行的三次侏儒黑猩猩(Panpaniscus)野外研究所获得的数据。当两个单位组相遇时，不同单位组的成员之间的亲和性互动比同一单位组的成员之间的亲和性互动更频繁。侏儒黑猩猩群落在灵长类群落中是独一无二的，似乎与人类群落具有相同的基础。Ihobe和Kano在第26届日本非洲研究协会年会上发表了关于这一主题的初步研究。2.Ihobe研究了雄性侏儒黑猩猩之间的社会关系，并在日本灵长类学会第五届年会上发表了一篇初步论文。3.Idani在1984年、1986年和1988年参加了实地研究，他发现每名移民女性选择一名特定的常驻女性，并且她们之间经常发生亲和行为。他为Folia Plimatology撰写了一篇论文。4.Ihobe发表了一篇关于侏儒黑猩猩和红鞭毛虫对灵长类动物的种间相互作用的论文。5.TAKEMON研究了侏儒黑猩猩的声音交流，并对它们的声音进行了分类。这项研究的初步论文已在日本灵长类协会第五届年会上发表。6.Asato分析了侏儒黑猩猩食物中的营养成分。他和1988年参加野外考察的NSOLA正在分析万巴岛的植被数据。这一结果将发表在京都大学非洲研究专著上。7.长谷川和HAYAKI于1988年参加了坦桑尼亚马哈阿勒山脉的野外研究，他们研究了那里的普通黑猩猩，以便与对侏儒黑猩猩的研究进行比较。

This project aimed to analyze the data obtained in the field studies of pygmy chimpanzees (Pan paniscus), which carried out at Wamba, Zaire on three times from 1984 to 1988.1. When two unit groups encountered, affinitive and sexual interactions between the members of the different unit groups were more frequently observed than these between the members of the same unit group. The pygmy chimpanzee community is unique in the societies of Primates and seems to have the same basis of the human community. IHOBE, who participated in the field studies in 1986 and 1988, and KANO presented a preliminary study of this theme at the 26th annual meeting of Japan Association for African Studies. 2. IHOBE studied social relationships between male pygmy chimpanzees and presented a preliminary paper at the fifth annual meeting of Primate Society of Japan. 3. IDANI, who participated in the field studies in 1984, 1986 and 1988, found that each immigrant female selected one particular resident female and that affinitive behaviors frequently occurred between them. He contributed a paper to Folia Plimatologica. 4. IHOBE published a paper concerned with interspecific interactions between pygmy chimpanzees and red colobus on Primates. 5. TAKEMON studied the vocal communications of pygmy chimpanzees and classified the sounds of them. A preliminary paper of this study was presented at the fifth annual meeting of Primate Society of Japan. 6. ASATO analyzed the nutritions of food of pygmy chimpanzees. He and NSOLA, who participated in the field study on 1988, are analyzing the data of vegetation of Wamba. This result will be appeared in Kyoto University African Study Monographs. 7. HASEGAWA and HAYAKI, who participated in the field study at Mahale Mountains, Tanzania in 1988, studied common chimpanzees (Pan troglodytes) there for comparing with the study of pygmy chimpanzees.
