Abstract

Many species shift their distribution northwards due to changing climate, which may bring previously isolated species into contact. In some cases, this can lead to competition and crossbreeding among congeneric species. Due to milder winters, several hare species (Lepus spp.) have shifted poleward or to higher elevations and currently occur in sympatry. There are limited data on the spatial ecology of northern brown hares (L. europaeus), and on possible joint space use with mountain hares (L. timidus), although species are known to frequently crossbreed. We estimated home ranges of 12 brown and 12 mountain hares in eastern Finland using GPS telemetry. The total home-range median areas were 111 ha for brown hares and 105 ha for mountain hares. The median core areas of these species were 5 and 3 ha, respectively. Individual home ranges and core areas of the studied species overlapped. Interspecific interaction seems to be frequent during the breeding season, which also enables crossbreeding.

北半球半城市棕Hares（Lepus europaeus）和山地Hares（Lepus timidus）的家园范围

由于气候变化，许多物种的分布向北转移，这可能会使以前孤立的物种接触。在某些情况下，这可能导致同类物种之间的竞争和杂交。由于冬季较温和，一些野兔物种（Lepus spp.）已向极地或海拔较高的地区迁移，目前出现在同一群落中。关于北方棕兔（L.europaeus）的空间生态学，以及可能与山兔（L.timidus）联合使用空间的数据有限，尽管已知物种经常杂交。我们使用GPS遥测技术估计了芬兰东部12只棕色野兔和12只山兔的栖息范围。棕兔和山兔的总栖息地面积分别为111公顷和105公顷。这些物种的中位核心面积分别为5公顷和3公顷。研究物种的个体家园范围和核心区域重叠。在繁殖季节，种间相互作用似乎很频繁，这也使得杂交成为可能。

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.
