We analysed individual associations between mouflon (Ovis orientalis musimon) observed during one year in order to find ontogenetic patterns underlying the social structure of the population. A correspondence factorial analysis was performed on Simpson's coefficients to compare association profiles. No strong association was found between adults but some of the young adult females maintained a preferential bond with their mother until the age of three. Yearling males were firstly unstable in their social relations and subsequently developed a strong preference for peers (the preferred companion(s) of young adult males were always young adult males). Animals did not prefer to associate with other individuals of their own family (Wilcoxon test: n = 53; z = 0.463; a < 0.01). Localized abundant food sources caused large regroupings during spring. This was the only case where we noted a series of observations where the same unrelated animals were seen together. With the exception of the mother-offspring relationship, individual social preferences were based on the sex and age of the partner rather than on identity. The existence of social behaviour profiles dependent on sex and age is proposed to explain the above results.
我们分析了一年内观察到的摩弗伦羊（东方盘羊摩弗伦亚种）个体之间的关联，以找出该种群社会结构背后的个体发育模式。对辛普森系数进行对应因子分析，以比较关联概况。未发现成年个体之间有强烈关联，但一些年轻成年雌性在三岁前与母亲保持着优先联系。一岁雄性在社会关系上首先不稳定，随后对同伴产生了强烈偏好（年轻成年雄性的首选同伴总是年轻成年雄性）。动物不倾向于与自己家族的其他个体交往（威尔科克森检验：n = 53；z = 0.463；α < 0.01）。春季，当地丰富的食物来源导致大量重新聚集。这是我们唯一记录到一系列观察结果的情况，即看到相同的非亲属动物在一起。除了母子关系外，个体的社会偏好基于伴侣的性别和年龄而非身份。我们提出存在依赖于性别和年龄的社会行为概况来解释上述结果。
