“…Ilomantsi race: XX/XY 1 Y 2 af, bc, g/o, hn, i/p, j/l, kr, m/q, tu This race was described by Halkka et al (1987) in the east of Finland and from southern Karelia (Bulatova et al, 2000; our data; localities 9 10), but the limits of its advance to the south is unknown. The race may be placed in the East European Karyotypic Group and in the Finnish Karyotypic Family (go, hn, ip) (Orlov et al, 2004).…”

“…Localities of chromosome races of the common shrew in the context of the Late Valdai glacial period (Velichko et al, 1993 The Mologa race was first described in the Mologa River basin (Orlov et al, 1996) on the southern border of the ice sheet (locality 25). However, Bulatova et al (1999Bulatova et al ( , 2000 and Bystrakova et al (2003) also found the race in localities much further to the south in the Middle Volga River basin. Orlov et al (2003) suggested that the northern population from the Mologa basin is isolated and should not be grouped with the southern, Middle Volga, population.…”

“…The Manturovo race may be placed in the East European Karyotypic Group and in the North Dvina Karyotypic Family (go, hi, kq) (Orlov et al, 2004). This is a widespread race in the North Dvina and Upper Volga river basins (Bulatova et al, 2000;Kozlovsky et al, 2000;Bystrakova et al, 2003). The Manturovo race has been found relatively close to the southern border of the former ice sheet (localities 28 30).…”

ABSTRACT. The present distribution of common shrew chromosome races indicates that the region covered by the Late Valdai ice sheet was subsequently recolonised by populations from refugia near the glacial front. The similarity of chromosome races from Finland and the Urals can be considered convergent: identical karyotypes have been formed independently on the basis of metacentrics in common and the canalisation of karyotypes. Chromosome races that survived the glaciation in southern refugia (Kiev, Neroosa, Penza and Sok) did not contribute to the postglacial recolonisation of the region vacated by the ice sheet.

“…The most recent list of chromosome races of the common shrew Sorex araneus includes 13 races from European Russia (Wójcik et al, 2003), the majority of which were discovered in the last 10 years or so (Orlov et al, 1996;Bulatova et al, 2000;Kozlovsky et al, 2000;Bystrakova et al, 2003). Now the focus is shifting to a search for the contacts between these races (Bystrakova et al, 2003).…”

ABSTRACT. New information is presented on the distributional ranges of the West Dvina, Moscow, Neroosa, Serov, Sok and Yuryuzan chromosome races in European Russia. Our study provides chromosome data on 67 common shrews from 28 localities in various parts of the East European Plain and foothills of the Ural Mountains. No new chromosome races were discovered but our data added substantially to the known geographic range of the Serov race both north-and southwards from the Asian slopes of the Ural Ridge where it was first described. This race also extends into northern Europe far to the west of the Ural Ridge. The known distribution of the Neroosa race has also been considerably extended. These data allow us to predict locations for contact zones between the following pairs of races: West Dvina Moscow, Moscow Neroosa, Sok Serov.

Among 36 known chromosomal hybrid zones of the common shrew Sorex araneus, the Moscow–Seliger hybrid zone is of special interest because inter‐racial complex heterozygotes (F1 hybrids) produce the longest meiotic configuration, consisting of 11 chromosomes with monobrachial homology (undecavalent or chain‐of‐eleven: CXI). Different studies suggest that such a multivalent may negatively affect meiotic progression and in general should significantly reduce fertility of hybrids. In this work, by immunocytochemical and electron microscopy methods, we investigated for the first time chromosome synapsis, recombination and meiotic silencing in pachytene spermatocytes of natural inter‐racial heterozygous shrew males carrying CXI configurations. Despite some abnormalities detected in spermatocytes, such as associations of chromosomes, stretched centromeres, and the absence of recombination nodules in some arms of the multivalent, a large number of morphologically normal spermatozoa were observed. Possible low stringency of pachytene checkpoints may mean that even very long meiotic configurations do not cause complete sterility of such complex inter‐racial heterozygotes.
