Based on the long-term data on the provisioned troops of Japanese macaques of Iwatayama Monkey Park(Kyoto), the wild population of Yakushima(Kagoshima), the wild population of chimpanzees of Mahale Mts. National Park(Tanzania), and the wild troops of ring-tailed monkeys of Berenty Reserve(Madagascar), I have studied the competition and coexistence of female primates, as follows ;(1)Based on the data of Japanese macaques of Arashiyama, the long-term trends in matrilineal inbreeding among them were investigated. The results are consistent with the hypothesis that different degrees of kin relatedness are discriminated by individuals with respect to mate choice. (2)In Yakushima, the intergroup encounters of wild Japanese macaques were analyzed, and the new method to estimate group density by point census was studied. (3)For the females of ring-tailed lemurs at Berenty, their reproductive parameters and population dynamics changes were analyzed. Ring-tailed lemurs are essentially female philopatric, and all cases of troop divisions or evictions occurred in larger troops of 20 or more lemurs, probably because of severe female within-group competition. (4)The dual competition(within-group and inter-group competitions) of female ring-tailed lemurs and the balance sheet between these competitions were analyzed, in particular during the birth season. These results were published in the Scientific Journals. Now, (5)I am analyzing the long-term changes of dominance rank relations of both male and female ring-tailed lemurs of Berenty, and (6)I am also analyzing the asynchrony of ovulation of wild chimpanzee females from the viewpoint of female competition.

根据对京都岩田山猴园日本猕猴的长期供应群体、鹿儿岛屋久岛野生种群、马哈尔山野生种群的长期数据，国家公园（坦桑尼亚）和贝伦蒂保护区（马达加斯加）的野生环尾猴群，研究了雌性灵长类动物的竞争和共存，具体如下：（1）根据岚山日本猕猴的资料，探讨了它们之间母系近亲繁殖的长期趋势。结果是一致的假设，即不同程度的亲属关系的歧视，个人就择偶。(2)In屋久岛，分析了野生日本猕猴的群体间相遇情况，研究了通过点普查估计群体密度的新方法。（3）分析了贝伦蒂环尾狐猴雌猴的生殖参数和种群动态变化。环尾狐猴基本上是雌性的，所有的群体分裂或驱逐事件都发生在20只或更多的狐猴群体中，可能是因为严重的雌性群体内竞争。（4）分析了雌性环尾狐猴的双重竞争（群内竞争和群间竞争）以及这些竞争之间的平衡表，特别是在出生季节。这些结果发表在科学期刊上。现在，（5）我正在分析Berenty的雄性和雌性环尾狐猴的优势等级关系的长期变化，（6）我还从雌性竞争的角度分析了野生黑猩猩雌性排卵的规律。
