在波兰西南部弗罗茨瓦夫的城市化地区，我们分析了石貂和红狐的栖息地使用情况。我们比较了随机选择观测点的栖息地比例利用情况，并评估了与水源和城市边界距离的差异。这两个物种对栖息地的利用不同于我们从随机点得出的预期。石貂比红狐更频繁地使用高密度的住房，并且从随机点出发，避开开放和工业区，而红狐使用住宅区的频率明显高于预期，并且避开高密度的住房。这两个物种根据它们的可用性使用其他栖息地。石貂通常选择靠近市中心的栖息地，而红狐通常选择比预期更靠近城市边界的栖息地。红狐和石貂的分布受到几个因素的影响，包括住所和食物的可用性，以及不被发现的移动机会。种间竞争也可能在生境选择中起重要作用。石貂似乎比红狐更适应城市化地区。(C) 2013年德国科学技术协会。Elsevier GmbH出版。版权所有。
We analyzed the habitat use of stone martens and red foxes based on incidental observations within the urbanized zone of Wroclaw, SW Poland. We compared proportional habitat use at observation sites with randomly selected points and evaluated differences in distance to the water sources and to urban boundaries. Habitat use by both species was different from what we had expected from random points. Stone martens used high-density housing more frequently than red foxes and that expected from random points and avoided open and industrial areas, whereas red foxes used housing estates significantly more often than expected and avoided high-density housing. Both species used the other habitats according to their availability. Stone martens often selected habitats located closer to the city centre, whereas red foxes often selected habitats closer to urban borders than expected. The distribution of red foxes and stone martens is influenced by several factors including the availability of shelter and food, as well as the opportunity to move around undetected. Interspecific competition may also play an important role in habitat selection. Stone martens seem to be better adapted to urbanized areas than red foxes.
