Abstract

Thirty nine samples of striped field mice (Apodemus agrarius coreae Thomas) from eight localities in the Korean peninsula were used for the analyses of mitochondria1 DNA (mtDNA) fragment patterns resulted from the digestion with eight restriction enzymes. A total of 31 fragments were recognized and seven mtDNA clones were revealed: one clone consisted of 32 among 39 samples from eight localities (1 of 1 from Sogcho, 4 of 5 from Mt. Chiak, 3 of 3 from Mt. Weolak, 2 of 2 from Mt. Sogri, 2 of 2 from Mt. Deokyoo, 3 of 4 from Mt. Jiri, 2 of 4 from Haenam, and 15 of 18 from Cheongju). The nucleotide-sequence divergences (p) among seven mtDNA clones ranged from 0.2% to 2.3% and distinct subgroups were not resulted from the grouping of these clones. It is confirmed that striped field mcie from the Korean peninsula is a single subspecies of Apodemus agrarius (A. agrarius coreae) because they were not divided into separate subgroups in their mtDNA genotypes.
