Combining morphological, ecological and genetic analyses, we compared patterns of diversification within and among populations of the southern Siberian whitefish species Coregonus lavaretus pidschian (Gmelin) to illuminate their evolutionary history. Using sequencing data from 1,930 bp of NADH dehydrogenase subunit 1 (ND1) mitochondrial DNA regions, we documented phylogeographic relationships among populations and developed a phylogeny of mtDNA haplotypes. We found significant differences in the perforated lateral-line scale numbers within and between some populations. Clear differences in the number of gill rakers on the first branchial arch were only exhibited between populations of C. l. pidschian and Coregonus lavaretus pravdinellus Dulkeit. Concordance between different morphological groups based on two meristic traits and mtDNA patterns was also tested.
