描述了生活在葡萄牙西南部栓皮栎林中的欧亚獾（Meles Meles Linnaeus, 1758）的活动节奏和运动模式。本文介绍了6个人20个月的无线电跟踪数据。獾表现为黄昏或夜间活动，通常在日落之后开始，在日出之前结束，平均每天活动8.26小时。这些参数有一些季节变化，但没有证据表明性别或月光有任何影响。然而，风速似乎与范围广泛的运动有关。在开始运动和日落或停止运动和日出之间没有发现显著的相关性。獾平均每晚移动4378米。雄性通常比雌性有更广泛的活动，可能是因为母性行为限制了雌性的活动范围。连续日利用集间的平均距离为295 m，且有季节差异，2000/2001年春季和2000年夏季的集间距离较大。居住在我们研究区域的栓皮栎林地的獾显示出较低的集保真度，低于北部同行，特别是英格兰低地的獾。只有36%的情况下，它们会回到同一个窝里睡觉，雌性更经常回到同一个窝里。在一个集合中连续停留的平均天数在春季较高，在夏季较低。
Activity rhythms and movement patterns of Eurasian badgers (Meles meles Linnaeus, 1758) inhabiting a cork oak woodland in SW Portugal are described. Twenty months of radio-tracking data for six individuals are presented. Badgers showed crepuscular or nocturnal activity, generally starting after sunset and ending before sunrise, being active on average for 8.26 hours per day. There was some seasonal variation in these parameters, but there was no evidence of any effect due to sex or moonlight. Nevertheless, wind speed seems to be associated with wide-ranging movements. No significant correlation was found between the onset of activity and sunset or between cessation of activity and sunrise. On average, badgers travelled 4378 m per night. Males usually had more extensive movements than did females, probably because maternal behaviour restricted female ranging. The mean distance between setts used on consecutive days was 295 m, and differed seasonally, being greater in spring 2000/2001 and summer 2000. Badgers inhabiting the cork oak woodland of our study area revealed lower sett fidelity than reported for their northern counterparts, especially those of lowland England. Only on 36% of occasions did they come back to sleep in the same sett, with females returning more often to the same den. The mean number of consecutive days spent in a sett was higher in spring and lower in summer.
