Movement and activity patterns are important components of life history, being central to resource acquisition and defense, mating behavior, and individual survival and fitness. Here, we present results from the 1st systematic radiotracking study of the masked palm civet (), a widespread viverrid found in subtropical and tropical forests of Asia. From June 2004 to November 2007, we radiotracked 12 masked palm civets (5 males and 7 females) in central-south China. Mean individual home-range size based on 95% minimum convex polygons was 192.6 ha ± 42.6 (range = 64-451 ha). Although males had larger mean home-range sizes than females (276.8 and 136.5 ha, respectively), these differences were not statistically significant. Males also exhibited greater daily movement distances and extents than females, but we found no evidence of sexual dimorphism in body size. Masked palm civets were predominantly nocturnal, but were active intermittently during the day. No significant seasonal (monthly) differences in daily activity patterns were apparent. We did, however, observe reduced hours of activity-but not continuous inactivity-during winter; consequently, we concluded that our study animals did not hibernate or semihibernate. We speculate that our observations of home-range overlap among individuals may indicate group living in the masked palm civet.
运动和活动模式是生活史的重要组成部分,对于资源获取与防御、交配行为以及个体生存和适应性至关重要。在此,我们展示了对食蟹獴进行的首次系统无线电跟踪研究的结果,食蟹獴是一种广泛分布于亚洲亚热带和热带森林中的灵猫科动物。2004年6月至2007年11月,我们在中国中南地区对12只食蟹獴(5只雄性和7只雌性)进行了无线电跟踪。基于95%最小凸多边形计算的平均个体家域面积为192.6公顷±42.6(范围 = 64 - 451公顷)。尽管雄性的平均家域面积大于雌性(分别为276.8公顷和136.5公顷),但这些差异无统计学意义。雄性的日移动距离和范围也大于雌性,但我们未发现体型存在两性差异的证据。食蟹獴主要在夜间活动,但白天也会间歇性活动。日活动模式没有明显的季节性(月度)差异。然而,我们确实观察到冬季活动时间减少,但并非持续不活动;因此,我们得出结论,我们研究的动物不冬眠或半冬眠。我们推测,我们观察到的个体间家域重叠现象可能表明食蟹獴存在群居生活。
