Five distinct chromosome races of the common shrew Sorex araneus Linnaeus, 1758 including different metacentrics with monobrachiat homology have been found in Poland. Their karyotypes include polymorphic arm combinations, and chromosomal forms differing in numbers of acrocentrics can be distinguished among them. The relationship between Polish and other European races of the common shrew has been examined by phylogenetic analysis using parsimony. Five phylogenetic groups of the common shrew, two of them consist only of one race, can be recognized in Europe. The Polish races belong to two groups: the West European and East European phylo­genetic groups. A model of chromosomal evolution in the common shrew consisting of two components, an allopatric one and a parapatric or stasipatric one, has been proposed. This model is based on the distribution of different races and different metacentrics in karyotypes of shrews in Poland and in central Europe.

Morphometric differentiation between the Manturovo and Serov chromosome races of the common shrewSorex araneus Linnaeus, 1758, in Northeastern European Russia was studied using 27 measurements of the skull in 953 specimens. Discriminant and cluster analyses showed that shrews belonging to different chromosome races were well differentiated. No regular dependence between morphological changes of the skull and longitude was observed and there was no association between geographic and morphological distance. Multiple regression analysis revealed that 24.7% of the total morphological variance could be explained by seven geoclimatic variables. We suggest that karyotypic divergence may play a significant role in differentiating skull morphology in the Manturovo and Serov races of the common shrew. We also suppose that selection may affect the skull morphology of different chromosome races in this species.

Multiannual variation is one of several types of species morphological variability, one that is directly related to ecophenotypic and evolutionary responses to changing environments. The morphology of small mammal populations can change quickly because generation length is short, usually one year, and individual lifespans are often only a year or two. We studied the response of skull and mandible morphology in the common shrew Sorex araneus Linnaeus, 1758 to nine climate factors related to snow cover, temperature and precipitation at a study site near Syktyvkar, Russia through the period 1976 to 2003. We found that these multivariate phenotypes changed significantly from year to year, though there were no clear directional trends in the change. The phenotype itself was closely associated with the range of annual temperature and winter precipitation. Changes in summer temperatures and precipitation seem to drive change in size-related phenotypes, whereas changes in snow cover and winter temperature seem to drive change in shape.

In Central Poland, two similar chromosome races of the common shrewSorex araneus Linnaeus, 1758 were earlier described: Drnholec race (arm combinationsgm, hi, ko, nr) and Stobnica race (gm, hi, ko, np). Great similarity in size and G-banding patterns between thenr andnp metacentrics leave open to doubt the actual existence of both races in Poland. The present study, which is based on good quality karyotypes of common shrews from 18 sites, showed the presence of thenr arm combination. There is therefore strong evidence that thenp arm combination was wrongly described and thus the Stobnica race should not be considered valid.

We review data on the chromosomal variation in the common shrew Sorex araneus Linnaeus, 1758 in the context of recent molecular findings. The article considers all aspects of chromosomal variation in this species: within-population polymorphism, karyotypic races, hybrid zones between karyotypic races, chromosomal evolution, and speciation. The recent molecular data provide vital information on different evolutionary processes such as inbreeding, genetic drift, population expansion, and selective forces. In particular, the molecular data challenge traditional models for the fixation of chro­mosomal variants, provide new insights into the manner of spread of such variants once they are formed and allow in-depth analysis of gene exchange between karyotypic races.

The red fox (Vulpes vulpes) has the widest global distribution among terrestrial carnivore species, occupying most of the Northern Hemisphere in its native range. Because it carries diseases that can be transmitted to humans and domestic animals, it is important to gather information about their movements and dispersal in their natural habitat but it is difficult to do so at a broad scale with trapping and telemetry. In this study, we have described the genetic diversity and structure of red fox populations in six areas of north-eastern Poland, based on samples collected from 2002–2003. We tested 22 microsatellite loci isolated from the dog and the red fox genome to select a panel of nine polymorphic loci suitable for this study. Genetic differentiation between the six studied populations was low to moderate and analysis in Structure revealed a panmictic population in the region. Spatial autocorrelation among all individuals showed a pattern of decreasing relatedness with increasing distance and this was not significantly negative until 93 km, indicating a pattern of isolation-by-distance over a large area. However, there was no correlation between genetic distance and either Euclidean distance or least-cost path distance at the population level. There was a significant relationship between genetic distance and the proportion of large forests and water along the Euclidean distances. These types of habitats may influence dispersal paths taken by red foxes, which is useful information in terms of wildlife disease management.

Here we present the first attempt to use the BovineSNP50 Illumina Genotyping BeadChip for genome-wide screening of European bison Bison bonasus bonasus (EB), two subspecies of American bison: the plains bison Bison bison bison (PB), the wood bison Bison bison athabascae (WB) and seven cattle Bos taurus breeds. Our aims were to (1) reconstruct their evolutionary relationships, (2) detect any genetic signature of past bottlenecks and to quantify the consequences of bottlenecks on the genetic distances amongst bison subspecies and cattle, and (3) detect loci under positive or stabilizing selection. A Bayesian clustering procedure (STRUCTURE) detected ten genetically distinct clusters, with separation among all seven cattle breeds and European and American bison, but no separation between plain and wood bison. A linkage disequilibrium based program (LDNE) was used to estimate the effective population size (N e) for the cattle breeds; N e was generally low, relative to the census size of the breeds (cattle breeds: mean N e = 299.5, min N e = 18.1, max N e = 755.0). BOTTLENECK 1.2 detected signs of population bottlenecks in EB, PB and WB populations (sign test and standardized sign test: p = 0.0001). Evidence for loci under selection was found in cattle but not in bison. All extant wild populations of bison have shown to have survived severe bottlenecks, which has likely had large effects on genetic diversity within and differentiation among groups.
