有蹄类动物具有从独居生活或一夫一妻制到大型群居群体的分级社会组织。人们指出，这种社会组织的等级与栖息地从封闭的森林到开放的草原或稀树草原的转变有关（Estes 1974，Jarman 1974）。母幼关系的解体，也称为家庭破裂，被认为与物种的社会组织有关，也可能与幼崽的性别有关。然而，迄今为止，家庭破裂的情况还没有得到很好的记录，特别是在山地有蹄类动物中，因为需要对已识别的个体进行长期观察。日本羚羊Capricornis Cripus通常单独生活，有时形成雄性、雌性配对单位或最多四个个体的家庭群体（Akasaka和Maruyama 1977，Kishimoto 1981，Sakurai 1981，Ochiai 1983b）。在日本羚羊中，后代达到独立的过程已有记录（Ochiai 1983a），但没有足够的关于独立后代建立领地的信息。本章旨在基于七年的野外连续观察，描述日本鬣羚的后代获得独立和建立领地的过程。
Ungulates have a gradational social organisation from a solitary life or monogamous pairs to large gregarious groups. This gradation of social organisation has been pointed out to be correlated with a shift in habitats from closed forest to open grassland or savannah (Estes 1974, Jarman 1974). The dissolution of the mother-young bond, otherwise called family break-up, is presumed to be related to the social organisation of the species, and possibly to the sex of the young. However, family break-up has not been well documented so far, especially in mountain ungulates, because long-term observations of identified individuals are required. The Japanese serowCapricornis crispususually lives alone, and sometimes forms male female pair units or family groups with up to four individuals (Akasaka and Maruyama 1977, Kishimoto 1981, Sakurai 1981, Ochiai 1983b). In the Japanese serow, the process of reaching independence by offspring has been documented (Ochiai 1983a), but there is not enough information on territory establishment by independent offspring. This chapter aims to describe the process of reaching independence, and that of territory establishment of offspring in the Japanese serow, based on continuous observations in the wild for seven years.
