“…Recent surveys have revealed that there are at least 11 karyotypic races of S. araneus in Poland, which differ from each other in their set of metacentric chromosomes, and some of which come into contact and form zones of hybridization (Wójcik 1993, Fedyk 1995, see Searle and Wójcik 1998 for review). The distinct karyotypic differences which are observed in S. araneus might be expected to act as efficient barriers to gene flow between races.…”

Morphometric differentiation among six chromosome races of the common shrew Sorex araneus Linnaeus, 1758 in Poland was examined by the use of 26 orthogonal mandibular measurements in 388 specimens. The discriminant function analysis (DFA) performed on 21 morphological variables led to a correct classification in 59.3% of cases. Comparison of morphological and chromosomal distances showed that there is no significant agreement; the two matrices were apparently discordant (cophenetic correlation coefficient, r coph = 0.216, p > 0.05). Multiple regression analysis revealed that 9.9% of the total morphological variance could be explained by eight geoclimatic variables. The DFA of residuals, remaining after regression of the morphological variables by the geoclimatic ones, let to correct assignment of only 26.3% specimens. Our research revealed that karyotypic divergence plays no important part in differentiating mandibular morphology in chromosome races of S. araneus, and morphological differences cannot be treated as a by-product of chromosomal speciation.

Onischenko S. S., Ilyashenko V. B., Searle J. B. and Borodin P. M. 2002. Morphometric difference between the Novosibirsk and Tomsk chromosome races of Sorex araneus in a zone of parapatry. Acta Theriologica 47: 381-387.A hybrid zone between the Novosibirsk and Tomsk chromosome races of the common shrew Sorex araneus Linnaeus, 1758 was found near Novosibirsk city (West Siberia, Russia) in an area unimpeded by geographic barriers. In this zone, the shrews of both races and their hybrids were trapped and karyotyped and 22 features of their cranial and postcranial skeleton were measured. Canonical discriminant analysis revealed 3 distinct groups of individuals, which corresponded to the 3 karyotypic categories involved in the analysis. The first discriminant function reflected the differences in the size of skeletal elements. The Novosibirsk shrews and the hybrids were significantly smaller than the Tomsk shrews. The second discriminant function was interpreted as a parameter of skeletal proportionality. The hybrids were significantly less proportional than the parental races. This study revealed one of the clearest examples of morphological differentiation between chromosome races of the common shrew.
