Morphometric differentiation between the Manturovo and Serov chromosome races of the common shrewSorex araneus Linnaeus, 1758, in Northeastern European Russia was studied using 27 measurements of the skull in 953 specimens. Discriminant and cluster analyses showed that shrews belonging to different chromosome races were well differentiated. No regular dependence between morphological changes of the skull and longitude was observed and there was no association between geographic and morphological distance. Multiple regression analysis revealed that 24.7% of the total morphological variance could be explained by seven geoclimatic variables. We suggest that karyotypic divergence may play a significant role in differentiating skull morphology in the Manturovo and Serov races of the common shrew. We also suppose that selection may affect the skull morphology of different chromosome races in this species.
