Abstract
Karyotypes of Apodemus peninsulae from the poorly studied Central Primorye at the Russian Far East have been studied. The species is widespreaded - from Western Siberia to the shores of the Pacific Ocean. It is characterized by polymorphism in terms of the number, size and morphology of supernumerary (B-) chromosomes. The material of the study based on 36 newly investigated, as well as 8 previously studied specimens from the Central Primorye. Animals are caught in the following localities of Primorsky Krai: 1) Pozharsky district, Krasny Yar, 1996 2) Krasnoarmeysky district, Melnichnoe, 1980 2013 3) Chuguevsky district, Bulyga-Fadeevo, Verkhne-Ussuri station, 1986 2008 4) Chuguevsky district, Lenino, 2012. Chromosomal preparations were made from bone marrow cells by a direct method. The number of B-chromosomes varied in different individuals from 0 to 5. Variability in the number and morphotypes of B chromosomes was revealed in the majority of animals (with the exception of 4). Rare morphotypes of B chromosomes are described, including new ones for this region: medium SM, small SM and ST, and also specimens without B chromosomes were found. There are similarities in the variability of the B chromosome morphotypes studied with populations from the East, South Primorye and in part with the Khabarovsk region. The new data are complement the earlier picture of the clinal karyotype variability in A. peninsulae associated with the loss of rare B chromosome morphotypes in the direction from the Southeast to the Northwest of the area. Apparently, this variability reflects the ways of colonization the species.
