Genetic variation and geographical structuring of vimba Vimba vimba were analysed across 26 sites (80 individuals) by means of mtDNA sequences (cyt b gene, mitochondrial control region) to localize hypothesized glacial refugia and to reconstruct postglacial recoloniation routes. Although genetic diversity among sequenced individuals was low, a combined analysis of the two sequenced fragments revealed a western (central and northern Europe: Danube, Elbe and lakes of Sweden) and an eastern clade (eastern Europe: Dnieper-South Bug, Don, Neman). Furthermore, a number of divergent ancestral haplotypes distributed around the Black and Caspian Seas became apparent. Mismatch analyses supported a sudden expansion model for the populations of the western clade between 50 and 10 000 bp. Overall, the study provides strong evidence for a northward and westward expansion of V. vimba from two refugial regions located in the Danubian drainage and the northern Pontic regions respectively.
采用线粒体 DNA 序列（细胞色素 b 基因、线粒体控制区）对 26 个地点（80 个个体）的维姆巴鱼（Vimba vimba）进行遗传变异和地理结构分析，以确定假设的冰川避难所，并重建冰川后再殖民路线。尽管测序个体之间的遗传多样性较低，但对这两个测序片段的综合分析显示出一个西部（中欧和北欧：多瑙河、易北河和瑞典湖泊）和一个东部分支（东欧：第聂伯河-南布格河、顿河、涅曼河）。此外，还出现了一些分布在黑海和里海周围的分歧祖先单倍型。不匹配分析支持西部分支群体在 50 到 10000 个碱基对之间的突然扩张模型。总的来说，这项研究为维姆巴鱼从多瑙河流域和北庞蒂克地区的两个避难所向北方和西方扩张提供了有力证据。
