“…Most of the previous studies of S. taranetzi along with other charr are restricted to an analysis of only short fragments of few mitochondrial and nuclear genes (e.g. Osinov et al 2017, and references therein).…”

The complete mitochondrial genome was sequenced in two individuals of Taranetz charr Salvelinus taranetzi. The genome sequences are 16,654 bp in size, and the gene arrangement, composition, and size are very similar to the charr genomes published previously. The difference between the two genomes studied is low, 0.05%. The present study confirms the independent taxonomic status of S. taranetzi within the genus Salvelinus. The level of sequence divergence between S. taranetzi and Salvelinus alpinus inferred from the complete mitochondrial genomes is relatively low (1.1%), indicating recent divergence of the species.

“…These populations bear CR haplotypes of mtDNA of northern Dolly Varden, which have been captured because of introgressive hybridization during the postglacial period. In particular, the charr population from Malyk Lake we preliminary refer to S. a. erythrinus (but not to S. a. taranetzi) despite ambiguous genetic markers data (Osinov et al 2017. Unfortunately, the samples of Arctic charr from Alaska and Arctic regions of Canada have not been included in our analysis.…”

“…In some cases, a capture of 'alien' mtDNA occurred in distinct populations (or local groups) due to introgressive hybridization. These cases are described for different species (Wilson and Hebert 1993;Wilson and Bernatchez 1998;Bernatchez et al 1995) and different phylogenetic groups of the S. alpinus -S. malma complex (Osinov et al 2017Esin et al 2017). In various representatives of the S. alpinus -S. malma complex, 'alien' mtDNA, most often, belongs to the haplogroup of northern Dolly Varden (Osinov and Mugue 2008;Taylor et al 2008;Alekseyev et al 2009;Moore et al 2015;Osinov et al 2017Osinov et al , 2018Esin et al 2017).…”

“…At this step, we employed two approaches that we implemented in two stages. The first stage, according to the mitonuclear and mito-morphological discordance (Osinov et al 2017, we excluded from the analysis those individuals of Arctic char and southern Dolly Varden from Asia which had mtDNA haplotypes of northern Dolly Varden (BER) as a result of introgressive hybridization (Table 1). Thus, we used on the second stage the reduced dataset of 57 specimens.…”

Evolutionary history, systematics and taxonomy of charrs of the genus Salvelinus and especially of the representatives of the S. alpinus -S. malma species complex remain confused that is connected with a substantial ecological and morphological flexibility of this group and with supposed ancient hybridization between some taxa. For the analysis of phylogenetic relationships and introgressive hybridization between the species of the genus Salvelinus including three endemic species from Lake El'gygytgyn and all main representatives of the S. alpinus -S. malma species complex, nucleotide sequences of mtDNA control region (960 bp) and two nuclear genes (ITS1 (581 bp) and RAG1 (899 bp)) were analyzed. The differences in the topologies of individual gene trees, among others reasons, were connected with incomplete lineage sorting and historical introgressive hybridization between certain taxa. Several cases of mtDNA capture by different taxa and phylogenetic groups were proposed. In particular, the following taxa participated in introgressive hybridization: northern Dolly Varden S. m. malma, representatives of the S. alpinus complex (including mainly Taranets charr S. a. taranetzi), southern Dolly Varden S. m. lordi from North America and bull trout S. confluentus. Main phylogenetic groups of the S. alpinus -S. malma species complex were revised. The origin and phylogenetic relationships of southern Dolly Varden from North America were not unambiguously defined. We proposed that introgressive hybridization had an important role in the evolutionary history of charrs, in particular, in the appearance of a high level of morphological, ecological and taxonomical diversity.

“…Что же касается гаплотипа Salv5, то он, возможно, относится к другой филогенетической линии арктического гольца, Сибирской (Siberia), которая встречается с Европейско-Сибирской линией как раз в районе Таймыра [8]. Аминокислотная последовательность белка, кодируемого нуклеотидной последовательностью с гаплотипом Salv5, отличается от последовательностей белка, кодируемого другим гаплотипом, выявленным нами, и такие различия, как мы предполагаем [6], могут ограничивать возможности гибридизации между носителями разных гаплотипов и даже вызывать в некоторых случаях постзиготическую репродуктивную изоляцию.…”

Samples from 11 populations of the Arctic char of the North-European part of Russia belonging to the anadromous and resident forms and two samples from Lake Sobach'e (Taimyr) were studied. The nucleotide sequence of the mitochondrial COI gene was determined in 60 individuals. In the majority of populations, the same COI haplotype was found. In some populations of the resident chars, haplotypes differing from the widespread haplotype in a single nucleotide substitution were found. The obtained genetic data give no reason to distinguish the resident form of the Arctic char from lakes of Karelia and the Kola Peninsula as an independent species, Salvelinus lep- echini. The adaptation of the Arctic char to the unstable environmental conditions is ensured primarily by its phenotypic plasticity.
