Karyotype and Relationships of the Endemic Char Salvelinus krogiusae from Dal'nee Lake (Kamchatka)

Karyotype and Relationships of the Endemic Char Salvelinus krogiusae from Dal'nee Lake (Kamchatka) Resident (lacustrine) chars, inhabiting many lakes of Kamchatka, Chukotka, and continental coast of the Sea of Okhotsk, are of particular interest for understanding the mechanisms of speciation and evolution of Salvelinus chars. Since one of these, the char from Dal'nee Lake (Paratunka River basin, southeastern Kamchatka), is substantially different from lacustrine-riverine and anadromous chars from the Paratunka River basin in several morphological traits, hemoglobin spectrum, ecology, and reproduction, it is considered an isolated species Salvelinus krogiusae. The karyotype of the resident char from Dal'nee Lake was shown to be variable in most individuals, containing 76 to 80 chromosomes in different cells, with NF = 98. This suggests that the variability of the chromosome number in this char form is explained by Robertsonian translocations. In females and males, cells with respectively 2n = 78 and 2n = 77 prevailed. Heteromorphic sex chromosomes were not found in the karyotype of this char species. Nucleolar-organizing regions (NORs) were mostly detected in the telomeric regions of short arms of large submetacentric chromosomes. These features of the Krogius char karyotype demonstrate that this species is isolated from other Kamchatka chars, being similar to Taranetz char S. taranetzi from Chukotka Peninsula, which is in good agreement with morphological data. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals
