这项研究详细介绍了银行田鼠，Clethrionomys glareolus，欧洲啮齿动物物种与森林栖息地密切相关的地理格局。我们使用的线粒体DNA细胞色素B基因的1011个碱基对的序列，从207个银行田鼠收集在62个地点遍布其分布区。我们的研究结果表明，存在三个地中海（西班牙，意大利和巴尔干半岛的）和三个大陆（西部，东部和“乌拉尔”）群。特有的地中海鱼类种群并没有对冰后期的古北界物种范围内的大部分物种的灭绝做出贡献。相反，这一地区的大部分地区显然是被在中欧冰川避难所生存的银行田鼠所征服的。此外，我们的地理分析还揭示了乌拉尔山脉和其他地方的银行田鼠的分化种群，它们携带另一种相关田鼠物种的线粒体DNA，红田鼠（Clethrionomys rutilus）。总之，这项研究表明，在欧洲的森林物种，是足够适应，面对气候变化，在残存的南部和北方栖息地生存的复杂的生态地理历史。中欧部分地区田鼠种群具有高水平的遗传多样性，这也凸显了这些地区作为种内遗传生物多样性来源的重要性。
This study details the phylogeographic pattern of the bank vole, Clethrionomys glareolus, a European rodent species strongly associated with forest habitat. We used sequences of 1011 base pairs of the mitochondrial DNA cytochrome b gene from 207 bank voles collected in 62 localities spread throughout its distribution area. Our results reveal the presence of three Mediterranean (Spanish, Italian and Balkan) and three continental (western, eastern and 'Ural') phylogroups. The endemic Mediterranean phylogroups did not contribute to the postglacial recolonization of much of the Palaearctic range of species. Instead, the major part of this region was apparently recolonized by bank voles that survived in glacial refugia in central Europe. Moreover, our phylogeographic analyses also reveal differentiated populations of bank voles in the Ural mountains and elsewhere, which carry the mitochondrial DNA of another related vole species, the ruddy vole (Clethrionomys rutilus). In conclusion, this study demonstrates a complex phylogeographic history for a forest species in Europe which is sufficiently adaptable that, facing climate change, survives in relict southern and northern habitats. The high level of genetic diversity characterizing vole populations from parts of central Europe also highlights the importance of such regions as a source of intraspecific genetic biodiversity.
