我们描述了艾伯塔省西南部的哥伦比亚地松鼠雄性在冬眠结束后的两个月内的领地间隔系统以及相关的攻击行为。成年雄性（>2岁）如果在其核心区域内追逐其他雄性的次数多于被其他雄性追逐的次数，则被归类为优势个体；如果情况相反，则被归类为从属个体。对于优势雄性来说，它们在核心区域内被追逐的互动比例远低于在核心区域外，而且从追逐和追逐逆转的位置可以明显看出一些相邻雄性之间有被保卫的边界。我们认为这些雄性维持着时空领地。对于从属雄性来说，它们在核心区域内和核心区域外被追逐的互动比例相似；在与任何有领地的雄性的大多数互动中它们都处于从属地位。地位（优势 - 有领地的或从属的）与年龄有关。大多数2岁和3岁的雄性是从属的；所有4岁及以上的雄性……
We describe the spacing system and associated aggressive behavior of male Columbian ground squirrels in southwestern Alberta for the 2 months following emergence from hibernation. Adult males (> 2 years old) were classified as dominant if they chased other males more than they were chased by them within their core areas and subordinate if the reverse was true. For dominant males, the proportion of interactions in which they were chased was much less within their core areas than outside them, and defended boundaries between some pairs of adjacent males were apparent from locations of chases and chase reversals. We consider these males to maintain spatiotemporal territories. For subordinate males, the proportion of interactions in which they were chased was similar inside and outside their core areas; they were subordinate in most interactions with any territorial male. Status (dominant–territorial or subordinate) was related to age. Most 2- and 3-year-old males were subordinate; all males of 4 years or old...
