Evidence of dispersal between the Yenisei and the Lena river basins during the late Pleistocene within the whitefish (Coregonus lavaretus pidschian) complex

The Coregonus lavaretus (Linnaeus, 1758) complex is a morphologically and genetically diverse group of whitefish. Its taxonomic structure has been controversial for almost century. At least 25 forms C. have described in Siberia, but there still no consensus on their intraspecific taxonomy. pidschian (Gmelin, 1789) was as subspecies lavaretus. Recently, it assumed that this also complex. purpose study to compare the distributions pidschian-like whitefish haplotypes two basins large Siberian rivers, Yenisei Lena, assess gene flow between these which were connected after last glaciation. sequence following mitochondrial DNA genes, 16S rRNA (partial), tRNA-Leu (full), NADH dehydrogenase subunit 1 tRNA-Ile tRNA-Gln used inference genetic l. pidschian. Whitefish clustered into groups according distribution river basins; however, shared indicating events migration hybridization, could occur when Bolshoi Lena systems glaciation (the Late Pleistocene).
