This research project aims to analyze organizing and maintenance mechanism of the promiscuous society of Japanese macaques in terms of mate choice. The subject group is the enclosed Wakasa group in Primate Research Institute. The analysis of the relation between characteristics (age, dominance) of the both sex of mates showed that 1. Young males prefer to mate young females and high-ranking males prefer to mate middle aged or older females. Middle or lower ranking males showed opportunistic mating and performed single mounting, though they had no specific preference to mating partners. 2. The analysis of behavioral chains on mate choice and its rejection showed females rejects middle or lower ranking males more frequently than higher ones. The possibility of the influence of high-ranking males, however, can not be denied as the cause of this phenomenon. 3.Reproductive success of males and females were clarified by the DNA paternity test. The results are now being compared with the resu … More lts of 1 and 2 above.This year Dr.Massirno Baridi joined this project and conducted research the social and hormonal correlates of maternal behavior in two macaque groups (Macaca fuscata, M.mulatta), housed at the Primate Research Institute. We studied tested several different hypotheses and found as follows : 1) that the social behavior of pregnant females shows significant changes during the late pre-partum and early post-partum and early post-partum period ; 2) that the marked fluctuation in the estrogen levels during the perinatal period is associated with the changes in social behavior ; 3) that the levels of estrogen metabolites were significantly correlated to different maternal styles ; 4) that infants of rejective mothers differed significantly in their behavioral repertoire than infants of protective mothers ; and, finally 5) that differences in groups compositions and environment affect both social and maternal behavior. The precise results of this research are currently in press or submitted in several papers shown in the list of publications. : Less

本研究旨在从择偶的角度分析日本猕猴混杂社会的组织与维持机制。该课题组为灵长类研究所封闭的Wakasa组。对两性特征(年龄、优势)之间的关系分析表明：1.年轻雄性更喜欢与年轻雌性交配，地位较高的雄性更喜欢与中年或老年雌性交配。中低级雄鸟表现出机会性交配，表现为单骑，但对交配伙伴没有特定偏好。2.对择偶和拒绝的行为链分析表明，女性拒绝中低级别男性的频率高于高级别男性。然而，不能否认高层男性影响的可能性，因为这是造成这种现象的原因。3.通过DNA亲子鉴定，明确了雄鼠和雌鼠的繁殖成功率。现在正在将结果与Resu…进行比较今年，Massirno Baridi博士加入了这个项目，并在灵长类研究所的两个猕猴群体(短尾猴和短尾猴)中进行了母性行为的社会和荷尔蒙相关性研究。我们研究检验了几种不同的假设，发现如下：1)怀孕女性的社会行为在产前晚期、产后早期和产后早期表现出显著的变化；2)围产期雌激素水平的显著波动与社会行为的变化有关；3)雌激素代谢产物的水平与不同的母亲风格显著相关；4)拒绝母亲的婴儿的行为模式与保护母亲的婴儿有显著差异；最后，群体组成和环境的差异既影响社会行为，也影响母亲的行为。这项研究的确切结果目前正在出版或以出版物清单中所列的几篇论文的形式提交。：较少
