通过全球定位系统技术，我们记录了狼（Canis lupus）从意大利亚平宁山脉北部到法国阿尔卑斯山西部的长距离传播。这是第一份关于狼在南欧以人类为主的地区长距离扩散的报告，提供了确凿的证据，证明阿尔卑斯地区狼数量的扩大源于亚平宁地区的自然再定居。通过穿越4条主要的4车道公路、农业区和几个区域和省级行政区，狼M15的传播轨迹显示出亚平宁和高山狼种群之间的单一、狭窄的联系。这种连通性应确保两个种群之间适度的基因流动，抵消潜在的瓶颈效应和减少高山狼种群的遗传变异性。我们报告的案例提供了一个例子，说明硬数据如何有效地减轻大型食肉动物种群自然扩张和再定居过程引起的公众争议。此外，通过强调这两个跨界狼种群之间的连通性，我们建议记录远距离扩散对于支持基于种群的跨界管理计划尤为重要。[j] .野生动物管理学报，73(8):1300-1306；2009)
By using Global Positioning System technology, we documented the long-distance dispersal of a wolf (Canis lupus) from the northern Apennines in Italy to the western Alps in France. This is the first report of long-distance dispersal of wolves in the human-dominated landscapes of southern Europe, providing conclusive evidence that the expanding wolf population in the Alps originates from the Apennine source population through natural recolonization. By crossing 4 major 4-lane highways, agricultural areas, and several regional and provincial jurisdictions, the dispersal trajectory of wolf M15 revealed a single, narrow linkage connecting the Apennine and the Alpine wolf populations. This connectivity should be ensured to allow a moderate gene flow between the 2 populations and counteract potential bottleneck effects and reduced genetic variability of the Alpine wolf population. The case we report provides an example of how hard data can be effective in mitigating public controversies originating from the natural expansion and recolonization processes of large carnivore populations. In addition, by highlighting the connectivity between these 2 transboundary wolf populations, we suggest that documenting long-distance dispersal is particularly critical to support population-based, transboundary management programs.
