Аннотация:In order to study the distribution of phylogenetic mtDNA lineages of Arctic charr Salvelinus alpinusin their contact zones in the north of East Siberia we analyzed nucleotide sequences of mtDNA controlregion of charr from 10 Arctic populations in the area from the Yenisei to the Lena. At the Putorana plateau,haplotypes of Atlantic and Siberian subgroups of Eurasian group were recorded, in the Khatanga River basin,haplotypes of Atlantic subgroup, in the Lena River delta, haplotypes of Siberian subgroup and of Beringgroup were observed. Some Siberian haplotypes found at the Putorana and in the Lena delta, have been earlierregistered in other regions of East Siberia. New findings, along with published materials allow to specifythe ranges of these three phylogenetic lineages and the margins of their contact zones; they also evidence widesympatry of Atlantic and Siberian haplotypes in Taimyr water bodies and support close relationship of charrof Siberian subgroup from all main areas of their distribution.
