项目摘要

The following results were obtained from an analysis of data on anti-chimpanzee hunting strategies of red colobus at the Mahale Mountains National Park, Tanzania ; 1) red colobus at Mahale adopted "Stand and defend strategy" against chimpanzee hunting. 2) they did not form mixed species associations with red tailed monkeys as anti-chimpanzee hunting strategy. Dr Uehara of Kyoto University and I revealed that the chimpanzees, at Mahale showed a rather euryphagous feature in terms of the selectivity of prey species from an analysis of data on abundance of eight species of diurnal mammals. I, Dr Uehara and Dr Boesch of Max Plunk Institute compared the interspecific relationships of chimpanzees and red colobus between Mahale and the Tai Forest National Park, Ivory Coast, and the following results were obtained from the comparison ; 1) the anti-chimpanzee hunting strategies of red colobus differed between the two study sites according to the difference of hunting techniques of chimpanzees, 2) these differences were related not only to the differences of vegetation types and climates but also to other factors such as "Prey images". I also analyzed the data collected during a field survey at the Kalinzu Forest, Uganda from 1999 to 2000, and the following results were obtained ; 1) there was a possibility that Abyssinian colobus were hunted by chimpanzees at Kalinzu, 2) the hunting techniques of chimpanzees at Kalinzu were resemble with these of Mahale or Gombe in Tanzania but not with Tai, 3) Abyssinian colobus at Kalinzu adopted "Hide strategy" against chimpanzee hunting.

从坦桑尼亚玛哈尔山国家公园的红色哥洛布省反奇义齐狩猎策略的数据分析得出以下结果； 1）马哈尔的红色哥洛布采用“立场和捍卫战略”，以抵抗黑猩猩的狩猎。 2）它们没有形成与红尾猴作为反chimpanzee狩猎策略的混合物种关联。我和京都大学的Uehara博士透露，在玛哈尔的黑猩猩从猎物物种的选择性方面表现出了相当富有的特征，从八种纵向哺乳动物的丰度数据分析中。我，马克斯·普林克研究所（Max Plunk Institute）的一世，乌哈拉（Uehara）博士和博伊斯（Boesch）博士比较了玛哈尔（Mahale）和象牙海岸的太极森林国家公园（Tai Forest National Park）之间的种间关系，并从比较中获得了以下结果。 1）根据黑猩猩的狩猎技术差异，红色糖果的抗奇异果狩猎策略不同，2）这些差异不仅与植被类型和气候的差异有关，还与其他因素有关，例如“猎物图像”。我还分析了1999年至2000年在乌干达的卡林祖森林进行的现场调查中收集的数据，并获得了以下结果。 1）有可能在卡林祖（Kalinzu）的黑猩猩狩猎阿比西尼亚果酱，2）卡林祖（Kalinzu）的黑猩猩的狩猎技术与坦桑尼亚的Mahale或Gombe的这些狩猎技术相似，但与Tai，Tai，3），3）Abyssinian colobus在Kalinzu Candted of Chard traublted Chrimpee''
