Geography of chromosomes in natural populations of Sorex araneus and Suncus murinus


, : Geography of chromosomes in natural populations of Sorex araneus and Suncus murinus. Genetika 33(8): 1126-1132, Aug

The geographic distribution of chromosome races of two shrew species (Sorex araneus and Suncus murinus) was analyzed on the basis of published data and personal results. It was shown that expansion of both species was accompanied by fixation of different chromosome rearrangements (mainly Robertsonian translocations) in isolates. Chromosome polymorphism studied from the viewpoint of ecology and geography of these species allows reconstruction of their evolutionary history and understanding of the speciation process.
