“…Three NEKG races are present in the vicinity of the Urals and are separated from the main NEKG stock by various intermediate races in northern Russia (Orlov et al, 2007;Shchipanov et al, 2008). In contrast to the southern species border in Russia (Bystrakova et al, 2007), the very limits of the species range in the north are still not fully specifi ed regarding chromosome races and karyotypic groups. In sum, one site of the Kanin chromosome race (a single specimen) was studied on the Kanin Peninsula, so far the most northern karyotypic description of the common shrew in Russia (Fredga, 1996a).…”

“…A single fi nding concerns the Yagry race on an island in the North Dvina River delta in the White Sea (Orlov et al, 2007). Better described are the more central Russian races Kirillov, Petchora, Serov, Sok and Manturovo (Bystrakova et al, 2007;Shchipanov et al, 2008Shchipanov et al, , 2009a. Here I describe the chromosomal characteristics of common shrews from close to the Kola Peninsula in Russia which may be interesting in view of the probable connection with Scandinavian chromosome races of the common shrew already well examined.…”

Abstract.A unique arm chromosome combination detected in the common shrew karyotype from a Karelian locality within the Arctic Circle (Kandalaksha State Nature Reserve, European Russia) is interpreted as a new chromosome race -Poyakonda. According to the standard nomenclature of G-banded chromosomes of Sorex araneus the karyotype contains the species specifi c bi-armed autosomes af, bc, jl, tu and the typical complex sex chromosome system (two metacentrics XX in the female and one metacentric/two acrocentrics XY 1 Y 2 in the male). A group of race specifi c chromosomes includes 4 metacentric combinations (hn, ip, kq, mo) and two acrocentric chromosomes (g and r). In all 5 shrew specimens examined the same homozygous autosome complement 2Na=20 was found. Data available from neighbouring regions in Russia and, in particular, from adjacent Fennoscandian countries reveal complex relationships between karyotypes of common shrews from the European North.

“…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.…”

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.

“…The Garevka is situated at a foothill region at about 300 m altitude, and the Jany is situated at a hill at about 550 m above sea level. The membership in a race was identified under karyological studies at each of the localities (Bystrakova et al, 2007;Shchipanov et al, 2011;. The Pechora race with gi, hn, jl, kq, mo, and pr diagnostic chromosomes, and the Manturovo race with go, hi, jl, kq, mn, and pr chromosomes represent the East European Karyotypic Group, EEKG (Orlov et al, 2004).…”

ABSTRACT. The shape of the skull, mandible, and first lower molar (m1) in 10 geographical samples from four chromosomal races of two karyotypic groups were studied using geometric morphometrics. Discriminant analysis with cross-validation was used to test the accuracy of classifications of specimens using skull shape. The percentage of correct classifications attributed to race varied from 61.8% to 89.5% and ranged from 51.6% to 82.3% for geographical samples. The structuring between races, as measured with Q st (this metric is analogous to F st , and the latter is used as a measure of genetic disparity between samples), was less than population-level structuring both within and between races. Variance between karyotypic groups in skull size, mandible, and molar shape was greater than between races. In skull shape, the variance was smaller as compared to the inter-racial level without larger "mountain" samples and greater when the entire set of samples was estimated. Interpopulation differences in all census characteristics were the most prominent. The magnitude of Q st in interpopulation estimations was similar both among populations of the same race and among populations of different races. Lack of correlation of Q st level with geographical distance between samples was found both in size and shape of the skull, mandible, and first lower molar. The significant difference between populations within a race was regarded as evidence of limitation of interpopulation migration. Each pair of geographic samples has a unique set of differentiating features. The stochastic variability of traits between the local samples, irrespective of race, is interpreted as evidence of genetic drift within partly isolated local populations. Diminishing differences between races could be a consequence of reabsorbing those stochastic morphological differences back into the metapopulations. The greater level of phenotypic differentiation between karyotypic groups compared to races is interpreted as a greater amount of time elapsed since the time of common ancestry.
