A wide hybrid zone of chromosome races of the common shrew, Sorex araneus Linnaeus, 1758 (Mammalia), between the Dnieper and Berezina Rivers (Belarus)
Karyological study of 75 specimens of the common shrew, Sorex araneus Linnaeus, 1758, from 8 localities in the Berezina River basin (eastern Belarus) was carried out. A wide hybrid zone (not less than 100 km) between the northern West Dvina chromosome race (XX / XYY, af, bc, gm, hk, ip, jl, no, qr,...

Karyological study of 75 specimens of the common shrew, Sorex araneus Linnaeus, 1758, from 8 localities in the Berezina River basin (eastern Belarus) was carried out. A wide hybrid zone (not less than 100 km) between the northern West Dvina chromosome race (XX / XYY, af, bc, gm, hk, ip, jl, no, qr, tu) and the southern Turov race (XX / XYY, af, bc, g, h/k, i, jl, m, n, o, p, q, r, tu) was revealed in this region. Frequencies of fused-unfused arms comprising four diagnostic metacentrics of the West Dvina race (g/m, h/k, n/o, q/r) were calculated in all capture sites. Taking into consideration the absence of metacentric ip in specimens from six northern localities, the Borisov (Bs) race (XX / XYY, af, bc, g/m, h/k, i, jl, n/o, p, q/r, tu) (Orlov, Borisov, 2009) was distinguished in these sites.
