Abstract：
The West European hedgehog (Erinaceus europaeus) is in decline, and it is important to identify its challenges. We used VHF-telemetry to monitor pre-hibernation space use, nest use, and hibernation sites in a suburban area in Norway. Based on nine adult hedgehogs tracked between August and November 2002, we found that home range size was not dependent on individual sex or weight and that home ranges overlapped between individuals regardless of sex. The distance moved was not dependent on individual sex, but there was a tendency for increased movement before dawn. The number of nests used per individual (0-10) and the number of nest switches (0-14) varied greatly and did not differ significantly between sexes. Out of 28 nest sites, 16 were linked to buildings and 12 to vegetation, and nesting material was most often grass and leaves. Three hedgehogs monitored until hibernation established winter nests under tree roots in natural forest patches in September, and this suggests that establishing or maintaining forest patches in urban areas is important to ensure suitable hibernation habitat for hedgehogs. Our study was limited by a low sample size, and additional research is required to gain a deeper understanding of the challenges hedgehogs face in urban environments.
摘要：
西欧刺猬（Erinaceuseuropaeus）正在衰落，重要的是要确定它的挑战。我们用甚高频遥测技术监测冬眠前空间的使用,巢的使用,和挪威郊区的冬眠场所。根据2002年8月至11月之间追踪的9只成年刺猬，我们发现家庭范围的大小不取决于个人的性别或体重，并且无论性别如何，个人之间的家庭范围都是重叠的。移动的距离不取决于个体性别，但是黎明前有增加运动的趋势。每个个体使用的巢数量（0-10）和巢开关数量（0-14）变化很大，并且在性别之间没有显着差异。在28个巢穴中，16个与建筑物有关，12个与植被有关，筑巢材料通常是草和树叶。对三只刺猬进行了监测，直到9月冬眠在天然森林斑块中的树根下建立了冬季巢，这表明，在城市地区建立或维护森林斑块对于确保刺猬适宜的冬眠栖息地很重要。我们的研究受到样本量低的限制，需要更多的研究来更深入地了解刺猬在城市环境中面临的挑战。
