The movement of 1763 badgers trapped between 36 social groups in Woodchester Park, Gloucestershire, over 18 years was analysed to determine the frequency and duration of moves, the factors associated with a predisposition to move and the spatial pattern of movements. Of those badgers whose capture history could be categorized, nearly half had moved. Of these, 73.1% were classified as 'occasional movers', 22.1% as 'permanent movers' and 4.8% as 'frequent movers'. Most adult badgers that moved made occasional moves (78.8%, n = 67). Cubs made all types of move including permanent moves (29%, n = 10). Seventy per cent of females were non-movers compared with 37% of males. Badgers were significantly more likely to move to smaller groups, whereas male badgers were significantly more likely to move to groups with a greater proportion of females. The spatial pattern of movement differed from the distribution of groups with bovine tuberculosis in the study area. However, temporal changes in movement were significantly related to the incidence of Mycobacterium bovis infection in the following year, indicating that as the movement of badgers between groups varies so does the incidence of bovine tuberculosis in the population. This finding is of central importance in the formulation of badger control policy.
对18年间被困在格洛斯特郡伍德切斯特公园36个社群之间的1763只獾的活动进行了分析,以确定移动的频率和持续时间、与移动倾向相关的因素以及移动的空间模式。在那些捕捉历史可分类的獾中,近一半有过移动。其中,73.1%被归类为“偶尔移动者”,22.1%为“永久移动者”,4.8%为“频繁移动者”。大多数移动的成年獾进行偶尔移动(78.8%,n = 67)。幼崽进行所有类型的移动,包括永久移动(29%,n = 10)。70%的雌性獾不移动,而雄性獾为37%。獾明显更倾向于移动到较小的社群,而雄性獾明显更倾向于移动到雌性比例更高的社群。移动的空间模式与研究区域内患有牛结核病的社群分布不同。然而,移动的时间变化与次年牛分枝杆菌感染的发生率显著相关,这表明随着獾在社群间移动情况的变化,种群中牛结核病的发生率也会变化。这一发现对于制定獾控制政策至关重要。
