“…On the contrary, it was earlier shown that charrs could interbreed at low effective ancestral population size (Moore et al, 2015;Taylor et al, 2008). We think that the founder effect or genetic drift following hybridization is likely the reason for S. malma malma mitochondrial Revealing mtDNA introgression may be the only method of reconstructing historical species ranges (Alekseyev et al, 2009;Yamamoto et al, 2006Yamamoto et al, , 2021. The study of the phylogeography of S. malma malma in most of the species range (Oleinik et al, 2014) indicated that S. malma malma colonization from the Bering refugium took place at the end of the Pleistocene and the beginning of the Holocene.…”

Many lacustrine charrs of the genus Salvelinus were described as separate species, and their origin and phylogenetic relationships are still under debate. In this study, we described the genetic variation of charrs from Lake Grand (Elikchan Lake Group, the mainland coast of the Sea of Okhotsk, Russia) and several locations outside of this system based on eight microsatellite (ms) loci and mitochondrial (mt) DNA control region. We tested the hypothesis of the resident charr membership to (a) the Arctic lineage of Salvelinus taranetzi sensu (Oleinik et al., Russian Journal of Genetics, 51, 2015, 55); (b) the Bering lineage of the Northern Dolly Varden Salvelinus malma malma; and (c) the Atlantic lineage of the Arctic charr Salvelinus alpinus. Analysis of phylogenetic relationships based on the mtDNA control region showed that all individuals from Lake Grand grouped with the Bering lineage. Bayesian analysis using msDNA supports the clustering together of charrs from Lake Grand and Arctic lineage, regardless of their mtDNA haplotypes. Incongruence between mtDNA and msDNA markers provided strong evidence of historical mtDNA introgression from S. malma malma to S. taranetzi. Patterns of divergence confirm a postglacial secondary contact of the representatives of Arctic and Bering lineages in the area of the Sea of Okhotsk coast and past hybridization in Lake Grand with the following features: (a) complete fixation of introgressed mtDNA of one species within populations of another and (b) absence of modern population of S. malma malma in the lake.

Anadromous migration of salmonid fish has been extensively studied, primarily focusing on the dichotomous framework of anadromy and residency. However, there remains a limited understanding of intermediate migratory behaviors within the anadromous framework. Our study aimed to classify the lifetime migration patterns of the anadromous white-spotted charr Salvelinus leucomaenis within and among populations using otolith annuli and Sr:Ca ratios. Initially, the migratory histories of anadromous charr were divided into two stages: “virgin sea-run stage” and “veteran sea-run stage”. The former was further categorized into three types: ocean entry at age ≥1+ years old, early descending, and brackish use. The latter was grouped into four types: annual migrants, frequent migrants, retired migrants, and ocean residents. We found that the proportion of migration patterns varied among rivers, with multiple patterns coexisting within the same river. Migration patterns typically involving 1–5 years spent in freshwater rivers followed by annual oceanic migrations were the most abundant, although diverse patterns were also observed. In the virgin sea-run stage, some individuals experienced the ocean at age 0+ years or brackish environments before their first sea entry. In the veteran sea-run stage, we found individuals who had resided in either the ocean or rivers for over a year. Retired migrants, characterized by stopping oceanic migration at a certain age and subsequently spending time in rivers, were exclusive to southern rivers. Conversely, ocean residents who spend one or more years in the ocean were more frequent in northern regions. Consequently, the lifetime migration patterns of anadromous white-spotted charr may exhibit stronger ocean dependency at higher latitudes. The implications of this study highlight the complexity and flexibility of migratory behaviors within and among white-spotted charr populations.
