Social Structure and Reproductive System of Primates

1. 本文分析了屋久岛野生日本猕猴(1)种群动态、(2)群内竞争、(3)雄猴种群间迁移、(4)社会机制等方面的数据。在此基础上，撰写了两篇文章，目前正在付印。对卷尾猴的社会结构和相互作用进行了分析。关于这个主题，有一篇文章正在出版。综述了人类和非人类灵长类动物在(1)性周期、(2)交配行为、(3)抚养后代和(4)雌雄竞争方面的研究成果。关于这些主题，目前有一本书正在出版。对日本岚山地区日本猕猴雌猴的产间隔期进行了分析。数据表明，生女儿的间隔期比生女儿的间隔期长，而且这种趋势与母亲的地位无关。现在，一篇文章正在准备中。本文对1968 ~ 1984年在岚山b群记录的日本猕猴的长期交配关系进行了分析。主要的主题是：(1)交配对的历时性变化；(2)雄性和雌性的终生生殖成功；(3)近亲交配的回避。

1. The data for the wild Japanese macaques of Yakushima Island on (1) population dynamics, (2) inter-and whithin-group competition, (3) inter-troop mobility of males, and (4) social mechanism were analyzed. Based on them, two articles were prepared, being in press now.2. The social structure and interactions of capuchin monkeys were analyzed. On this theme, one article was in press now.3. The data for the human and non-human primates on (1) sexual cycle, (2) the mating behaviors, (3) raising children, and (4) male and female competition were reviewed. On these themes, one book was in press now.4. The interbirth intervals of Japanese macaque females of Arashiyama, Japan were analyzed. The data suggest that the interbirth intervals following daughters were longer than those following daughters, and that this tendency was independent of the mother's rank. Now, one article is in preparation.5. The long-term mating relations of Japanese macaques recorded from 1968 to 1984 in the Arashiyama B-troop are being analyzed. The main themes are (1) diachronic changes of mating pairs, (2) life-time reproductive success of males and females, and (3) inbreeding avoidance.
