Abstract
The paper elucidates the features of colonization by whitefish ( Coregonus lavaretus L.) of water bodies of European Russia in connection with the Pleistocene glaciation events. Based on the data on the frequencies and phylogenetic relationships of mitochondrial DNA haplotypes, a significant role of migrants from the western periglacial refugia was shown. The first large refugium was located in the North Atlantic, and the other was placed in the South-East Baltic. Until the last glaciation, the maximum of which was observed about 20 thousand years ago, there were also migrations from Siberia. However, at present the descendants of these migrants in the water bodies of north-west Russia are not dominant. The size of the refugium may be an important condition for the successful spreading of the whitefish.
