赤狐（Linnaeus，1758）通常被认为是严格的领土动物，居住在不同的和分开的范围，这些捕食者的家范围可以从几十公顷的大小变化到多达20-30公里（2），因为狐狸似乎不可能以相同的强度来保卫大小如此不同的区域，对公布的数据进行了分析，以了解家域大小的变化如何影响以下参数：家域重叠、每天访问的区域和动物在24小时内行进的距离。结果表明，生活在大范围内的狐科（群）之间的重叠度远大于生活在小范围内的狐科（群）之间的重叠度，小范围内狐科（群）的日活动面积与季节性活动范围的比值大于大范围内狐科（群）的日活动面积与季节性活动范围的比值。日平均移动距离与家域大小无显著相关性（r =-0.118，p = 0.75）。这些结果表明，不同的模式的使用空间和差异的领土防御红狐居住在大，小范围。家域重叠的影响和强度之间的接触狐狸占领邻近范围的疾病传播进行了讨论。本文中发现的大范围之间的显着重叠是根据Andrzeubski（2002）的家域概念进行讨论的。
Red fox Vulpes vulpes (Linnaeus, 1758) are generally regarded as strictly territorial animals, inhabiting distinct and well-separated ranges, The home ranges of these predators can vary in size from a few dozen hectares to as much as 20-30 km(2), Because it seemed impossible that foxes could defend areas so different in size with the same intensity, the published data were analysed in order to see how changes in home range size could affect the following parameters: home range overlap, the area visited daily and the distance travelled by animals during 24 h. It was found that the overlap between fox families (groups) occupying large ranges was much greater than between foxes living in small ranges, The ratio of the area visited daily to the seasonal home range size was greater in small ranges than in large ones. No significant correlation was found between the mean distance moved daily and home range size (r = -0.118, p = 0.75). These results suggest different patterns of the use of space and differences in territorial defence by red foxes inhabiting large and small ranges. The implications of home range overlap and intensity of contacts between foxes occupying neighbouring ranges for the spread of disease are discussed. The significant overlap between large ranges found in this paper is discussed in the light of Andrzejewski's (2002) home range concept.
