“…In our BEAST analysis, the mean substitution rate of cyt b was estimated at 5.7% per My (95% HPD: 3.5-8.1). This phylogenetic rate is significantly lower than rate estimates employed for dating recent events in S. araneus and S. tundrensis (Bannikova et al, 2010;Raspopova et al, 2018Raspopova et al, , 2020.…”

In the present study, we reconstruct phylogenetic relationships within the chromosomally variable Sorex araneus species group based on 20 nuclear loci and the mitochondrial cyt b gene. In the species tree, Nearctic S. arcticus represents the earliest offshoot of the group followed by Holarctic S. tundrensis and Siberian S. daphaenodon. Five other species distributed mostly in Europe form a wellsupported clade. Coding regions showed stronger phylogenetic signal than introns. The results suggest a high incidence of reticulation in the evolution of the group. The authentic mitochondrial lineage of the Iberian shrew S. granarius was found to be close phylogenetically to S. coronatus, which confirms that some populations of the Iberian shrew S. granarius were introgressed from S. araneus.Footprints of deeper reticulations are revealed for the first time, indicating the potential hybrid origin of the S. arcticus and S. coronatus lineages. Ancient hybridisations are hypothesised to be the source of discordance between molecular-and karyotype-based phylogenetic reconstructions.

“…Reconstruction of the center of origin. The potential center of origin of the ancestral mitotype was recon-structed using the principle of maximum parsimony, as was proposed in a similar work on the Common Shrew (Raspopova et al, 2020). The purpose of this analysis was to use the connection between the geographical distribution of mitotypes and their phylogenetic relationships in order to determine the geographic placement of the ancestral mitotype, that makes the dispersal scenario of mitochondrial lineages over the area as parsimonious as possible.…”

We studied the polymorphism of the cytb gene in two forms of the Lesser White-toothed Shrew species complex: Crocidura suaveolens s. stricto and C. sibirica. The haplotypes of C. sibirica are found to be very similar to those of Crocidura suaveolens. They do not belong to a distinct haplogroup. The molecular diversity of the populations in the Asian part of the range is higher than in Eastern Europe. For the combined sample from Asia and Europe together, we revealed a significant signal of population expansion. Analysis of the expansion time showed that the Asian territory was colonized earlier (before the last glacial maximum) than the Eastern Europe (at the very end of the Late Pleistocene and in the early Holocene). The results of the ancestral area reconstruction are consistent with the hypothesis of a Middle Asian origin of the C. suaveolens/C. sibirica group, recent colonization of Inner Asia and later penetration into Eastern Europe.

The common shrew (Sorex araneus) is one of the most studied shrew species of the Western Palaearctic. Despite this, the general drivers underlying morphological variation still remain unclear. Here we provide evidence for contradictory effects of climatic and geographical factors on the mandible of the common shrew. At the continental scale there is a negative correlation between body- and skull-size and latitude and longitude but at regional scales such an association is often not apparent; in fact, in some cases body size and skull size follow the opposite trend and observations at various scales yielded contradictory results. We studied shrew mandibles using geometric morphometrics and tested for correlations of their size and shape with selected geographical and climatic variables. We examined 1155 mandibles from 29 European localities and found significant interpopulation differences in both size and shape. Centroid size negatively correlated with latitude. We also found that centroid size was significantly correlated with altitude and annual precipitation. Our results confirmed an inverse Bergmann’s rule relationship in S. araneus along the transect from the Baltic to the Adriatic Sea. Regarding mandible shape, Slovenian shrews were the most distant from all other studied populations. We discuss how altitude and precipitation can influence the morphology of the common shrew.
