There is a general perception that central and northern Europe were colonized by range expansion from Mediterranean refugia at the end of the last glaciation. Data from various species support this scenario, but we question its universality. Our mitochondrial DNA studies on three widespread species of small mammal suggest that colonization may have occurred from glacial refugia in central Europe-western Asia. The haplotypes on the Mediterranean peninsulae are distinctive from those found elsewhere. Rather than contributing to the postglacial colonization of Europe, Mediterranean populations of widespread small mammals may represent long-term isolates undergoing allopatric speciation. This could explain the high endemism of small mammals associated with the Mediterranean peninsulae.
人们普遍认为，中欧和北欧是在上一个冰川期末期从地中海避难所通过范围扩张而被殖民的。来自各种物种的数据支持了这一情况，但我们质疑其普遍性。我们对三种广泛分布的小型哺乳动物的线粒体DNA研究表明，殖民化可能发生在中欧 - 西亚的冰川避难所。地中海半岛上的单倍型与其他地方发现的不同。广泛分布的小型哺乳动物的地中海种群可能代表了正在经历异域物种形成的长期隔离种群，而不是对欧洲冰后期的殖民化有贡献。这可以解释与地中海半岛相关的小型哺乳动物的高度特有性。
