摘要

本土物种对欧洲景观的重新占领导致其种群密度和栖息地范围的变化。为了测试种群密度的增加是否会影响家庭范围的大小，我们研究了严格意义上的食草动物欧亚海狸（Castor fiber）。24只海狸被无线电跟踪，以揭示它们在不同种群密度下的家园范围。被占用海岸线的平均长度为2648.0±1530.6米。我们没有发现家庭范围大小和人口密度之间有任何联系。我们的研究结果表明，资源的可用性与场地占用的持续时间显著相关。因此，空间的使用主要取决于粮食资源的可用性，而不是人口密度的增加。

How Do the Beaver Home Ranges Vary during the Range Expansion?

Reoccupation of European landscapes by native species causes changes in their population densities and home ranges. To test whether an increase in population density affects home range sizes, we studied the strictly territorial herbivore Eurasian beaver (Castor fiber). Twenty-four beavers were radio-tracked to reveal their home ranges under varying population densities. The mean length of occupied shorelines was 2648.0 ± 1530.6 m. We did not find any linkage between home range sizes and population densities. Our results showed that the availability of resources was significantly associated with the duration of site occupation. Thus, the space use was primarily determined by the availability of food resources, rather than by rising population density.

期刊介绍： Annales Zoologici Fennici publishes mainly original research reports, but also in-depth reviews and commentaries on all aspects of animal ecology and evolution, and fields related to them. Our aim is to promote papers which focus on the interactions among various components in the past and present environments by using integrative and cross-disciplinary approaches. This may be achieved by employing tools from different fields of research, such as (but not restricted to): ecology and paleoecology, molecular ecology and phylogeography, conservation biology, human-induced contemporary evolution and wildlife management, animal behaviour and interactions (including recognition systems and mechanisms), paleontology (except systematics and taxonomy) and evolution, bioenergetics.
