“…This supports the use of the RAPD method in the resolution of genetic structure in the genus Sorex following previous successes in the genera Microtus (Potapov et al, 1999) and Sicista (Baskevich et al, 2004) and in the Lophuromys flavopunctatus species complex (Lavrenchenko et al, 2001(Lavrenchenko et al, , 2004. dance between the RAPD data and results from the analysis from mtDNA cytochrome b nucleotide sequence (Balakirev et al, 2007).…”

We analysed genetic divergence between species of the genus Sorex (S. araneus, S. caecutiens, S. minutus and S. minutissimus) using the RAPD (random amplified polymorphic DNA) method. We also examined RAPDs in 26 individuals of six chromosome races of the common shrew (Moscow, Ilomantsi, St. Petersburg, Neroosa, Penza, and Sok) from the European part of Russia. Nine primers were used for the detection of 24 to 79 fragments. The number of clearly identified DNA fragments by all primers was 539. Loci specific for different chromosome races of S. araneus were revealed. On the basis of summary matrices of the RAPD spectrum for nine primers, trees showing the genetic divergence were constructed. This study demonstrated the value of RAPDs for the analysis of relationship between species and chromosome races in Sorex.

“…Diagnostic metacentrics of the Kirillov race are found in the Yagry, Kanin, Manturovo and Pechora races. The similarity between the Kirillov race and other chromosome races of Northeastern Europe with respect to the cytochrome b gene (Balakirev et al, 2007) might be due to their reticulate evolution.…”

ABSTRACT. The present distribution of common shrew chromosome races indicates that the region covered by the Late Valdai ice sheet was subsequently recolonised by populations from refugia near the glacial front. The similarity of chromosome races from Finland and the Urals can be considered convergent: identical karyotypes have been formed independently on the basis of metacentrics in common and the canalisation of karyotypes. Chromosome races that survived the glaciation in southern refugia (Kiev, Neroosa, Penza and Sok) did not contribute to the postglacial recolonisation of the region vacated by the ice sheet.

“…We further included S. araneus sequences from GenBank: – , , – , , from Balakirev et al . (), and from (Mouchaty et al ., ). Using the software jModelTest 0.0.1 (Posada, ), the TrN+I+G model was identified as the best fitting model by the Akaike information criterion (AIC) and subsequently used for phylogenetic analysis.…”

Effects of late quaternary climate change on Palearctic shrews

The Late Quaternary was a time of rapid climatic oscillations and drastic environmental changes. In general, species can respond to such changes by behavioral accommodation, distributional shifts, ecophenotypic modifications (nongenetic), evolution (genetic) or ultimately face local extinction. How those responses manifested in the past is essential for properly predicting future ones especially as the current warm phase is further intensified by rising levels of atmospheric carbon dioxide. Here, we use ancient DNA (aDNA) and morphological features in combination with ecological niche modeling (ENM) to investigate genetic and nongenetic responses of Central European Palearctic shrews to past climatic change. We show that a giant form of shrew, previously described as an extinct Pleistocene Sorex species, represents a large ecomorph of the common shrew (Sorex araneus), which was replaced by populations from a different gene-pool and with different morphology after the Pleistocene Holocene transition. We also report the presence of the cold-adapted tundra shrew (S. tundrensis) in Central Europe. This species is currently restricted to Siberia and was hitherto unknown as an element of the Pleistocene fauna of Europe. Finally, we show that there is no clear correlation between climatic oscillations within the last 50 000 years and body size in shrews and conclude that a special nonanalogous situation with regard to biodiversity and food supply in the Late Glacial may have caused the observed large body size.
