This study analyzed nucleotide sequences of mtDNA control region of Arctic charr in East Siberia and identified haplotypes of Atlantic, Siberian and Bering subgroups in their contact zones. The research specified the ranges of these three phylogenetic lineages and the margins of their contact zones, providing evidence of wide sympatry of Atlantic and Siberian haplotypes in Taimyr water bodies and supporting close relationship of charr of Siberian subgroup from all main areas of their distribution.
In order to study the distribution of phylogenetic mtDNA lineages of Arctic charr Salvelinus alpinus in their contact zones in the north of East Siberia we analyzed nucleotide sequences of mtDNA control region 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 Bering group were observed. Some Siberian haplotypes found at the Putorana and in the Lena delta, have been earlier registered in other regions of East Siberia. New findings, along with published materials allow to specify the ranges of these three phylogenetic lineages and the margins of their contact zones; they also evidence wide sympatry of Atlantic and Siberian haplotypes in Taimyr water bodies and support close relationship of charr of Siberian subgroup from all main areas of their distribution.
