Abstract
The phylogenetic relationships of burbot (Lota lota L., 1758) of the Volga–Kama River basin are reconstructed for the first time. The sequences of the gene cytochrome b and the mtDNA control region obtained for 44 samples from the Kama River and Mezhevaya Utka River (the Volga River tributaries) are studied. New haplotypes of both markers were revealed. The results of phylogenetic reconstructions based on cytochrome b and control region mtDNA do not contradict the existing ideas about the phylogenetic structure of the species, and indicate inclusion of burbot from the Volga–Kama basin in Eurasian haplogroup. According to obtained data, the Volga–Kama River basin could play an important role in shaping the genetic diversity of burbot in Europe, and during certain periods it served as a corridor connecting the river systems of the European and Asian parts of the species range.
