The spatial occupation of female Corsican mouflon (Ovis ammon) in medium Mediterranean mountains of southern France, was studied between the end of 1987 and June 1989. It can be divided into two seasonal home ranges, one in fall/winter, and one in spring/summer. Both seasonal home ranges start with a period of intense locomotive activity in the different individuals. This behaviour could be explained by a general inclination of the animals to move on large scale, the expression of this inclination being allowed by the favourable environmental conditions in spring and fall. In any case, the comparison of our results with those obtained from mountain populations of the genus Ovis, suggests that 'phylogenetic inertia' exists towards certain modalities in spatial occupation. Indeed, the observed seasonal movements do not seem to retain a real adaptive character in our Mediterranean study area, as shown by the overlap of ranges, the use of the same type of habitat during the seasons and the great variability between individuals.
1987年末至1989年6月期间，对法国南部地中海中部山区的雌性科西嘉摩弗伦羊（盘羊）的空间占据情况进行了研究。其可分为两个季节性活动范围，一个在秋冬季节，另一个在春夏季节。两个季节性活动范围都始于不同个体的一段高强度移动活动期。这种行为可以用动物大规模移动的普遍倾向来解释，而这种倾向的表现是由春秋季有利的环境条件所允许的。无论如何，将我们的结果与从盘羊属山地种群获得的结果进行比较，表明在空间占据的某些模式方面存在“系统发育惯性”。事实上，在我们的地中海研究区域，观察到的季节性移动似乎并没有保留真正的适应性特征，这表现为活动范围的重叠、季节间对同一类型栖息地的利用以及个体间的巨大变异性。
