“…Atlantic salmon Salmo salar was used as outgroup. The detailed laboratory protocol of mtDNA analysis was described earlier [11][12][13]. In accordance with the objectives of the study, different sets of 20 restriction endonucleases (MBI Fermentas, Lithuania; SibEnzyme, Russia) were used, including AsuI, AvaI, AvaII, BstNI, BstUI, DdeI, EcoRV, HhaI, HinfI, MboI, MboII, MspI, RsaI, StyI, BsuRI, VspI, BclI, SspI, Bme1390I, and TaqI.…”

“…Recent genealogical analysis of mtDNA haplotypes showed that the observed pattern most likely was the consequence of a complex combination of several factors in the back ground of ancestral polymorphism preservation [12,13]. However, at the present stage, it is impossible to see the difference between the influence of incomplete lineage segregation and historical introgression, as well as to estimate the gene flow in the young taxa pre serving ancestral polymorphism [36].…”

“…However, despite the large number of publications [5-17 and others], no generalized phylogeny of the mitochon drial groups, which would agree with morphological phylogeny of the genus Salvelinus, has previously been constructed. Our studies of the genetic differentiation and divergence in charrs of the genus Salvelinus with PCR RFLP analysis of mtDNA fragments [11][12][13] provided insight into the evolution of the main phylo genetic groups of charrs. However, the proposed hypothesis was not free of the limitations associated with the composition of the examined taxa and the characters.…”

Charrs of the genus Salvelinus (including Salvethymus) represent a monophyletic group of salmo nid fishes that diverged from the common ancestor without subdivision into subgenera. The phylogenesis of the genus is characterized by four cycles of mitochondrial genome divergence. The first one, belonging to the Late Miocene-the border between Miocene and Pliocene (6 to 4 million years ago)-was associated with the consecutive divergence of the S. fontinalis, S. namaycush, S. levanidovi, and S. leucomaenis basal branches. Two divergence events, including separation of the ancestral lineage of Western Pacific group of S. m. krascheninnikovi and the following segregation of the common ancestor into two mitochondrial phyla, happened within the period of 3 to 2 million years ago. The next cycle is attributed to the time interval of about 1 million years ago and includes the divergence of both phyla. In one phylum, a relatively quick isolation of Arctic and Eastern Pacific phylogroups, along with the divergence of the latter phylogroup into S. confluentus and S. m. lordi lineages, took place. At the same time, the second phylum diverged into the S. m. malma and S. alpinus phylogenetic groups. At the final stage (Middle to Late Pleistocene), differentiation of the taxa within the phylogenetic groups took place.

The northern Dolly Varden, Salvelinus malma malma, is a typical representative of arctic fauna distributed in northeastern Asia and northwestern North America. Because its spawning habitats were affected by Pleistocene glacial advances over most of its natural range, S. m. malma is among the most interesting objects of phylogeographic and microevolutionary studies. We reconstructed the genealogy of mtDNA haplotypes from 27 Alaskan and Asian populations to study the influence of glacial and geological vicariance events on the contemporary population genetic structure, phylogeographic subdivision and distribution of the northern Dolly Varden. Analysis of restriction site states in three PCR-amplified mtDNA regions (ND1/ ND2, ND5/ND6, Cytb/D-loop; 47% of the mitochondrial genome) resolved 75 haplotypes in 436 fish. Similar patterns of subspecific variation apparent from hierarchical diversity and nested clade analyses of mtDNA haplotypes identify weak spatial differentiation and low levels of divergence. Our results suggest that (1) demographic history has been influenced by historical range expansions and recent isolation by distance, (2) present populations from Asia and North America were colonized from one main Beringian Refugium, and (3) that this taxon's ancestral population probably experienced a bottleneck in the Beringian Refugium during the late Pleistocene (Wisconsin) glacial period.

“…The genus Salvelinus (commonly referred to as char) contains six widely recognized species: Bull Trout Salvelinus confluentus, Brook Trout S. fontinalis, Lake Trout S. namaycush, Dolly Varden S. malma, Arctic Char S. alpinus, and Whitespotted Char S. leucomaenis. The existence of additional Salvelinus species and subspecies has also been recognized or suggested (Dunham et al 2008;Oleinik and Skurikhina 2010). The genus is known for a high degree of phenotypic plasticity and variation in life history types (e.g., resident, migratory, anadromous; Dunham et al 2008).…”

Novel SNP Genotyping Assays Facilitate Species Identification of Salvelinus Collected in a Recreational Fishery

Members of the genus Salvelinus often occur sympatrically, exhibit a high degree of phenotypic plasticity, and commonly hybridize. These factors often complicate species identification and hybrid detection based solely on morphology. Many species and populations of Salvelinus are threatened or endangered and accurate species identification and hybrid detection are important for conservation. Single nucleotide polymorphism (SNP) markers offer several advantages over other classes of genetic markers for species identification. We used DNA sequences from six species of Salvelinus to identify 16 SNPs that exhibited fixed differences among species and 16 additional SNPs that were variable within different species. These markers were used for species identification of putative Bull Trout Salvelinus confluentus that were misidentified as Lake Trout S. namaycush in a recreational fishery in Lake Pend Oreille, Idaho. The markers developed in this study will be useful for Salvelinus species identification and provide important data for conservation efforts. . We also thank Matt Smith and Jennifer Von Bargen for providing laboratory assistance, Rob Ryan for providing information on the recreational fishery in Lake Pend Oreille, and Denise Hawkins and Patty Crandell for reviewing an earlier version of this manuscript. The findings and conclusions in this manuscript are those of the authors and do not necessarily represent the views of the U.S. Fish and Wildlife Service.
