利用长期的母系数据、微卫星分析和行为测试，我们检验了野生日本猕猴(Macaca Fuscata)的个性差异是否与加性遗传效应、母体影响或属于特定的社会群体有关。新对象测试引发的行为由与新对象谨慎相关的成分(Ob-PC1)定义，而新食品测试引发的行为由与消耗性反应相关的成分(Fo-PC1)和新食物谨慎相关成分(Fo-PC2)定义。Ob-PC1的重复性中等，不显著；Fo-PC1和Fo-PC2的重复性中等，显著。线性混合效应模型发现，性别、年龄、性别、×年龄、供应、试验次数、日期、一天中的时间、季节和与最近的猴子的距离与个性无关。对两岁以上的女性进行的线性混合效应模型发现，排名高的人对新奇物体更加谨慎。线性模型被用来确定性别、年龄、群体成员、母亲的亲属关系或亲属关系是否对二人组的人格相似性有独立的影响。这些分析发现，生活在同一组中的一对猕猴在对待新事物时的谨慎程度不那么相似，关系更密切的一对猕猴在吃新食物的倾向上更相似，而同一组中的一对猕猴在对待新食物时的谨慎程度更相似。总而言之，这些发现表明，这群野生猴子的个性是由等级、遗传效应和群体效应驱动的，后者可能包括开发环境中不同生态位的需要。本文的在线版本(doi：10.1007/s10329-0160572-9)包含补充材料，授权用户可以使用。
Using long-term maternal pedigree data, microsatellite analysis, and behavioral tests, we examined whether personality differences in wild Japanese macaques (Macaca fuscata) are associated with additive genetic effects, maternal influences, or belonging to a particular social group. Behaviors elicited by novel-object tests were defined by a component related to caution around novel-objects (Ob-PC1) and behaviors elicited by novel food-tests were defined by correlated components related to consummatory responses (Fo-PC1) and caution around novel foods (Fo-PC2). The repeatability of Ob-PC1 was modest and not significant; the repeatabilities of Fo-PC1 and Fo-PC2 were moderate and significant. Linear mixed effects models found that sex, age, sex × age, provisioning, trial number, date, time of day, season, and distance to the closest monkey were not related to personality. Linear mixed effects models of females older than 2 years found that high rank was associated with greater caution around novel objects. Linear models were used to determine whether sex, age, group membership, maternal kinship, or relatedness had independent effects on the personality similarity of dyads. These analyses found that pairs of macaques that lived in the same group were less similar in their caution around novel objects, more closely related pairs of macaques were more similar in their tendency to eat novel food, and that pairs of macaques in the same group were more similar in how cautious they were around novel foods. Together, these findings suggest that personality in this population of wild monkeys was driven by rank, genetic effects, and group effects, the latter possibly including the need to exploit different niches in the environment.
