discussion

Discussion: Apodemus group. Most closely related to A. chevrieri as reflected by morphology (see that account). Phylogenetic analyses of mtDNA cytochrome b and nuclear IRBP sequences clearly identified A. chevrieri and A. agrarius as sister-species that are part of a larger clade composed of A. peninsulae, A. draco, A. semotus, A. latronum, and A. speciosus, which represents an evolutionary radiation separate from that producing the Japanese A. argenteus and Nepalese A. gurkha (Liu et al., 2004; Suzuki et al., 2003). Noteworthy morphological studies bearing on systematics of European populations are: seasonal changes in gut morphology, and the relationships between allozyme heterozygosity and gut morphology (Borkowska, 1995; Borkowska and Ratkiewicz, 1996); research on the thymus (Bazan-Kubik and Skrzypiec, 1992); and comparisons between postnatal development of German A. agrarius and A. sylvaticus (Pelz et al., 1996). Age and geographic variation in Eurasian, Chinese, Korean, Polish, Bulgarian, and Yugolavian populations documented by results from morphometric analyses (Koh, 1983, 1991; Koh and Tikhonova, 1998; Koh et al., 1997, 1998 a, b; Kryštufek, 1985 b; Liu et al., 1991; Siko

Order Rodentia - Family Muridae

distribution

Distribution: Palearctic and Oriental regions in two disjunct segments. One from C Europe (from S Finland, Baltic region, through Poland and C Germany to NE Italy and through the Balkan countries to Greece, Romania, Bulgaria, and Turkish Thrace; Mitchell-Jones et al., 1999; Petrov, 1992; Vohralík, 1992; Vohralík and Sofianidou, 1992 b) east to the Caucasus, parts of Kazakhstan and Kyrgyzstan, and west of Lake Baikal region and adjacent Mongolia and NW China (Xinjiang). The other portion from the Amur River region in far E Russia extending through Korea (including some offshore islands) and westward through China from northern reaches of Nei Mongol and Heilongjiang in the northeast to W Yunnan (Wang, 2003; Zhang et al., 1997); also in the small Senkaku Isl group of Japan (Kaneko, 1994) and on Taiwan (M. - J. Yu, 1996). Expansion of geographic range due to anthropogenic pressures reported by Karaseva et al. (1992).
