日本serow（Capricornis crispus）的空间行为，适应森林栖息地相对稳定的食物供应和气候条件，如久坐的习惯，小的家庭范围，和很少的季节性变化的栖息地选择。然而，以前没有进行调查，在开放的山区栖息地具有较高的季节性变化。因此，我研究的空间行为的日本长鬃羚在一个开放的山区山。富士，日本中部，基于GPS定位数据。与森林栖息种群相比，这些山地长尾羚的年度活动范围要大得多（雌性：316.5公顷，雄性：373.1公顷）。春季和夏季的家域最大，冬季的家域最小，为最大值的20.3%-56.1%。有限的饲料和冬季恶劣的气候条件似乎推动了这种能量最小化的行为策略。植被类型和海拔的选择随季节变化，可能是因为饲料供应和气候条件的变化。这些空间行为在山地居住的serow类似于几个相关的山区有蹄类动物，这意味着这些行为是适应高度季节性开放的山地栖息地。我的研究结果表明，影响空间行为的主要因素是栖息地的特点，如气候，饲料丰富，和季节性。这些研究结果提供了支持的生态模式有蹄类动物的空间行为，即封闭的栖息地促进小而稳定的家域，而开放的栖息地促进大和季节性波动的家域。
The Japanese serow (Capricornis crispus) exhibits spatial behavior adapted to forest habitats with relatively stable food supply and climatic conditions, such as sedentary habits, small home ranges, and little seasonal variation in habitat selection. However, investigations have not previously been conducted in open mountainous habitats with high seasonal variability. Therefore, I examined spatial behavior of the Japanese serow in an open mountainous region of Mt. Fuji, central Japan, based on GPS location data. These mountain-dwelling serows had much larger annual home ranges (female: 316.5 ha, male: 373.1 ha) compared with forest-dwelling populations. Spring and summer home range sizes were the largest, and winter home range size was the smallest, ranging from 20.3%–56.1% of maximum. Limited forage and harsh climatic conditions in winter seemed to drive such energy-minimizing behavioral strategies. Selection of vegetation types and elevation varied seasonally, likely because of changes in forage availability and climate conditions. These spatial behaviors in mountain-dwelling serows resemble those of several related mountain ungulates, implying that these behaviors are adaptations to highly seasonal open mountainous habitats. My findings suggest that the main factors affecting spatial behavior are habitat characteristics, such as climate, forage abundance, and seasonality. These findings provide support for an ecological pattern in ungulate spatial behavior whereby closed habitats promote small and stable home ranges, whereas open habitats promote large and seasonally fluctuating home ranges.
