项目摘要

Field researches both in a topical forest and an open land in Africa was conducted to clarify the feature of adaptation and process of dispersion of cercopiethecid monkeys in forests and into open lands.Research in a forest was conducted at the Nature Reserve of Ipassa-Mingouri in Gabon this year following the previous year. Hamada accompanied a research collaborator Okayasu (Howletts Institute, United Kingdom). In the vocal communication studies of colobus monkeys and cercopiethecid monkeys they collected vocal response of monkeys to vocal sounds of individuals in their own group and those in the neighbouring groups. Then they analyzed the vocal repertory and the function of the collected data of vocal sound. They also collected the data on foraging behaviours and food items of monkeys following the previous year. (conducted mainly by Okayasu). Hamada collected the morphological data on locomotion mastication and vocalization of colobus and cercopiethecid monkeys.Research in a savanna was conducted at Kala Maloue National Park in Cameroon by Ohsawa, Agetsuma, Njifoti (Foreign investigator of this research project) and Chatani (research collaborator: JSPS post-doctoral researcher). Following surveys were conducted. 1. Data on foraging activity dairy rhythm and food items of patas monkeys in the rain season were collected (Agetsuma). 2. Data on terrestrial locomotion patterns of patas monkeys were collected through observation and in videotapes. Date on whole day long of 2 individuals of each year from 0.5 to 4.5 were collected (Chatani). 3. The process of supplanting of the harem male of one-male group by a solitary male was investigated through direct observation. In this year submissive males were observed to copulated more frequently than the males in average.

为了弄清长尾猴在森林和开阔地的适应和扩散过程的特征，在非洲的森林和开阔地进行了实地研究。继去年之后，今年在加蓬的Ipassa-Mingouri自然保护区进行了森林研究。Hamada陪同研究合作者Okayasu（联合王国豪利茨研究所）。在对疣猴和长尾猴的声音交流研究中，他们收集了猴子对自己群体中个体和邻近群体中个体的声音的声音反应。然后分析了所采集的声乐数据的声乐库和功能。他们还收集了去年猴子觅食行为和食物的数据。（主要由冈康主持）。Hamada收集了疣猴和长尾猴的运动、咀嚼和发声的形态学数据。Ohsawa、Agetsuma、Njifoti（本研究项目的外国研究员）和Chatani（研究合作者：JSPS博士后研究员）在喀麦隆Kala Maloue国家公园的热带草原进行了研究。进行了以下调查。1.收集了在雨季的觅食活动、乳节律和食物项目的数据（Agetsuma）。2.通过观察和录像收集了斑腿猴的地面运动模式数据。从0.5到4.5收集每年2个个体的全天数据（Chatani）。3.通过直接观察，研究了孤雌体取代单雄体群体中的后宫雄体的过程。在这一年，顺从的雄性被观察到比平均雄性交配更频繁。
