“…As judged by the current distribution of acrocentric chromosomes in common shrew populations in Belarus (Mishta et al, 2000;), a local chromosome race with acrocentric karyotype was distributed more widely in Glacial epoch than now. Five animals with 10 acrocentric pairs were found to the south of Berezino (this paper).…”

“…Metacentrics no and qr were not found in two southern capture sites of the Borisov race. The hk combination is widespread in eleven chromosome races from the basins of rivers Wisla, Bug, Neman, and West Dvina, including the West Dvina and Lepel races, which representatives were found in Belarus close to the localities studied here (Mishta et al, 2000;Bulatova et al, 2000;). This metacentric chromosome has probably introgressed into populations with acrocentric chromosomes earlier than other metacentrics.…”

“…As for Common shrews from two southern localities (Berezino vicinity) with 9 pairs of acrocentric chromosomes should be referred to the Turov race (Mishta et al, 2000) (XX / XYY, af, bc, g, h/k, i, jl, m, n, o, p, q, r, tu) described from Turov Distr. in southern Belarus; the Turov race extends from the Pripyat River (the left bank) to the right bank of River Berezina.…”

Abstract. 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. Common shrews from two southern localities on the right and left banks of the Berezina River (Berezino vicinity) were referred to the Turov race. The presence of four metacentrics descended from the West Dvina race in the Bs race testifi es to the hypothesis expressed earlier that the polymorphic populations of the S. araneus between the Dnieper and Berezina Rivers originated as a result of the West Dvina race spreading from the north and of hybridization between this race and local populations with acrocentric chromosomes.

“…The Neroosa race (go, hi, kr, mn, and p/q;Bulatova et al 2000) is monomorphic for four Rb translocations throughout its large distribution range in the Oka and Don River basins (Bystrakova et al 2007). The acrocentric chromosomes g, o, k, and r were noted at some sites in Ukraine (Mishta et al 2000) and near the Belarusian boundary, in the vicinity of Novozybkov city (see Suppl. material 1) where 2NA varied from 19 to 25 (Bulatova et al 2000, Sheftel andKrysanov 2002).…”

The distribution area of the Białowieża race (g/r, hn, ik, m/p, o, r;Fredga and Nawrin 1977) stretches from eastern Poland to western Belarus (Mishta et al, 2000;Borisov et al 2016). The West Dvina race (gm, hk, ip, no, qr;Bulatova et al 2002) occupies a vast territory from the Valdai Hills to the Smolensk Upland, its southern boundary passes through Vitebsk region of Belarus (Bulatova et al 2002, Orlov and Borisov 2009.…”

The common shrews, Sorex araneus Linnaeus, 1758, inhabiting the territory of Belarus, are characterized by a significant variation in the frequency of Robertsonian (Rb) translocations. The frequency clines for translocations specific of three chromosome races: the West Dvina (gm, hk, ip, no, qr), Kiev (g/m, hi, k/o, n, p, q, r), and Białowieża (g/r, hn, ik, m/p, o, q) have already been studied in this territory. In this communication we report new data on polymorphic populations with Rb metacentrics specific of the Neroosa race (go, hi, kr, mn, p/q) in south-eastern Belarus, analyse the distribution of karyotypes in southern and central Belarus and draw particular attention to the fixation of the acrocentric variants of chromosomes in this area. The results show that certain Rb metacentrics specific of the Neroosa, West Dvina, Kiev, and Białowieża races (namely, go and pq; ip; ko; hn and ik, respectively) are absent in many polymorphic populations. Thus, the karyotypic differentiation of S. araneus in the studied area is determined by unequal spread of different Rb translocations and by fixation of acrocentric variants of specific chromosomes.
