项目摘要

In this research project, the following four research activities were conducted ; 1. the comparative ecology of the sympatric gorillas and chimpanzees in Zaire and Congo, 2. the study of forest structure of tropical forests and interactions between primate community and fruit production, 3. morphological studies of Cercopithecus species in Zaire, and 4. invitations of two researchers from Zaire to Japan.In the tropical forests, the sympatric gorillas and chimpanzees were different each other in their feeding ecology. The most characteristic feature of gorillas in Congo in comparison with those in Zaire was that they used to go inside the swamp to feed water plants.In the montane forest of Zaire, the meat eating behavior and tool using behaviors were observed. The medical plant usage by gorillas were suggested by fecal analysis, which was similar to the medical plant usage of chimpanzees in Tanzania.It was found that the forest of the study site in Zaire was composed of small forest patches with few dominant species by using a super-long transect method. However, in the study site of Congo, the three vegetation types were clearly found. The three types of fruits production were categorized concerning seed dispersion. The features of the fruits were seemed to combined with the behavior of their seed dispersors in the context of coevolution.The allometry of brain size and body weight among Cercopithecus were studied.Dr. N. MWANZA was invited in 1990 to Japan to study the ecology of sympatric apes. Mr. M. MWANGA were also invited in 1991 to Japan to study the morphology of Cercopithecus species.

在本研究项目中，进行了以下四项研究活动：1。扎伊尔和刚果同域分布的大猩猩和黑猩猩的比较生态学; 2.热带森林结构及灵长类群落与果树生产的相互作用研究。形态学研究的Cercopithecus物种在扎伊尔，和4。在热带森林中，同域分布的大猩猩和黑猩猩的摄食生态是不同的。与扎伊尔大猩猩相比，刚果大猩猩最具特色的特征是它们经常进入沼泽地觅食水生植物，在扎伊尔山地森林中观察到肉食行为和工具使用行为。粪便分析表明，大猩猩对药用植物的利用与坦桑尼亚黑猩猩对药用植物的利用相似。而在刚果的研究地点，这三种植被类型都很明显，三种果实生产类型都是根据种子散布来分类的。在协同进化的背景下，果实的特征似乎与其种子传播者的行为相结合。姆万扎于1990年应邀前往日本研究同域猿类的生态学。Mr. M. 1991年，MWANGA还应邀前往日本研究Cercopithecus物种的形态。
