项目摘要

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

该研究项目旨在分析日本猕猴的滥交社会的组织和维护机制。该学科是灵长类动物研究所的封闭式Wakasa组。对伴侣性别的特征（年龄，优势）之间关系的分析表明，1。年轻的男性更喜欢年轻女性和高级男性更喜欢与中年或年龄较大的女性交配。中层或较低排名的男性表现出机会性交配并进行了单次安装，尽管他们对交配伙伴没有特定的偏好。 2。对伴侣选择及其排斥反应的行为链的分析表明，女性比较高的男性更频繁地拒绝中间或更低的男性。然而，高级男性影响的可能性不能被否认为这种现象的原因。 3。通过DNA亲子鉴定阐明了男性和女性的生殖成功。现在将结果与上述1和2的RESU…相比。今年，Mamassirno Baridi博士加入了该项目，并进行了研究，在两个猕猴团体（Macaca Fuscata，M.Mulatta）中，社会和马匹相关性与灵长类动物研究所所住的社会相关性。我们研究了几种不同的假设，发现如下：1）怀孕女性的社会行为在美产后和产后早期和产后早期时表现出显着变化； 2）围产期期间雌激素水平的明显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材料样式显着相关； 4）与受保护母亲的婴儿相比，拒绝母亲的婴儿在行为库中显着不同；最后5）组成和环境的差异会影响社会和母性行为。这项研究的确切结果目前在媒体上或在出版物列表中显示的几篇论文中提交。：较少的
