  • Univariate and multivariate analyses of morphometric characters were performed with samples of three subspecies of striped field mice (Apodemus agrarius coreae, A. agrarius pallescens, and A. agrarius chejuensis). It was found that the samples of A. agrarius chejuensis from Jeju-Do were distintc from those of the other two subspecies from the Korean peninsular, whereas subspecies coreae was similar to subspecies pallescens: it is concluded that A. agrarius pallescens is a synonym of A. agrarius coreae. Further analyses will be needed to clearify the subspecific status of A. agrarius chejuensis.

  • Striped filed mice from Jeju-Do (Apodemus agrarius chejuensis) were used for morphometric and chromosomal studies in order to compare them with striped field mice from the korean peninsula (A. Agrarius coreae). It was found that A.agrarius chejuensis and A. agrarius coreae are similar in karyotypes and it was confirmed that the former is a large-size group and the latter is a small-size group.

  • Univariate and multivariate analyses of morphometric characters were performed with samples of striped field mice, Apodemus agrarius coreae Thomas, collected from Mt. Taebaek area, Mt. Wolak area, Mt. Palgong area, and Chongju area. It was confirmed that the samples of A. agrarius coreae were similar with one another to be grouped into a single subspecies. Moreover, clinal variation related with the altitude of localities where samples were collected was revealed in the first axis resulted from discriminant analysis and in the length of tail vertebrae.

  • 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.

  • The partial sequences of mtDNA cytochrome b gene in two subspecies of striped field mouse(Apodemus agrarius coreae and A. agrarius manchuricus) from Korea and northeast China were analyzed to determine the degree of genetic diversity in ech subspecies and to confirm their subspecific difference. In 18 specimens of A. agrarius coreae, ten haplotypes were resulted, and in two specimens of A. agrarius manchuricus. one haplotype was revealed. Tamura-Nei nucleotide distance among ten haplotypes in subspecies coreae ranged 0.36 to 1.86%. and nucleotide distance between two subspecies (coreae and manchuricus) was 0.37 to 1.47%: maximum infrasubspecific divergence in coreae was greater than maximum intersubspecific difference between two subspecies. Moreover, no major subgroup was resulted when 11 haplotypes in two subspecies were compared. Our sequence result was not cancordant with the morphological data studied so far, and it is concluded that cytochrome b gene sequence is not a good genetic marker to distinguish two subspecies of A. agrarius. In futurem, mtDNA control region analyses seemded to be necessary to reveal genetic relationship between these two subspecies of A. agrarius.

  • Age variation and secondary sexual dimorphism in four external and 27 cranial characters of 102 specimens of striped firld mice, Apodemus agrarius coreae Thomas, from Cheongju, Korea, were analyzed statistically. Specimens were classified as subadults, young adults, middle-aged adults, and old adults, and variation of morphometric characters among the four age classes was evident. Significant secondary sexual dimorphism among sexes of the same age class was not revealed. Teh specimens of the same age class have to be used in further analyses to clarify geographic variation of morphometric characters in Apodemus agrarius from Korea.

  • In order to determine the taxonomic status of Apodemus agrarius chejuensis from Cheju island in Korea, three hundred and eleven samples of eight subspecies of striped field mice (subspecies, agrarius, ningpoensis , pallidior, chevrieri, insulaemus, manchuricus, coreae, and chejuensis of A. agrarius Pallas) in Asia, collected from Turkey , China, Taiwan, , Manchuria, and Koarea, were used. Four external and 27 cranial characters were measured and their measurements were utilized for multivariate analyses such as cluster, principal component, and discriminant analyses. Four forms were revealed . A largest-size from was chejuensis, whereas a large-size form was cheverieri. A medium -size from and a small-size from were coreae and other five subspecies (agrarius , ningpoensis, pallidior, insulaemus, and manchuricus) , respecitvley, but their differences were clinal. A discontinuous gap was revealed between chejuensis (a largest-size from) and six subspecies ( a medium-size from and a small-size form) Although chejuensis appeared to be a distinct species, it is concluded that molecular analyses are necessary in order to describe it as a new species.

  • Specimens of five species of Apodemus(A. agrarius, A. chevrieri, A. draco, A. latronum, and A. peninsulae) from east Asia (Korea and China) were used for numerical taxonomic analyses with 31 external and cranial characters. Two groups and eight subgroups within them were recognized: [I; a large-size form; (A. agrarius chejuensis), (A. chevrieri), (A. draco orestes and A. latronum), and(A. peninsulae peninsulae and A. p. preator)], [II; a small-size form; (A. agrarius coreae), (A. agrarius manchuricus, A. a. ningpoensis, and A. a. pallidior), (A. draco draco), and (A. peninsulae sowerbyi)]. Conclusions based on morphometric analyses are such as followings: 1) Morphometric characters appeared not to be useful in order to distinguish two subgenera in Apodemus (Apodemus and Alsomys), 2) further analysis is necessary to determine whether or not A. draco and A. latronum are conspecific, and 3) A. a. chejuensis is in morphometric characters the largest form among five species of Apodemus studied. Moreover, it is confirmed: 1) A. agrarius, A. chevrieri, and A. peninsulae are distinct species, 2) A. draco and A. latronum are not conspecific with A. peninsulae. 3) Three forms of A. agrarius (large-size form, medium-size form, and small-size form) can be recognized as three subspecies [(A. a. chejuensis), (A. agrarius coreae), and (A, a, ningpoensis including A. a. manchuricus and A. a. pallidior)], 4)A. draco draco and A. draco orestes are distinct subspecies, 5) A. peninsulae peninsulae (including A. p. preator) and A. p. sowerbyi are distinct subspecies.

  • Samples of ho subspecies of striped field mice, Apodemus agrarius coreue & Apodemus ograrius cheiuensis, from four localities in Korea were used for the analyses of mitochondrial DNA fragment patterns resulted from the digestion with eight restriction enzvmes. A total of 31 fragments were recognized and 15 clones were revealed. The 15 clones were grouped into four major subgroups. One sample from Cheongiu was distinct, and formed one of the four major subgroups: the mean divergence wi6 other subgroups was 4.6 per cent, and extensive analyses using samples from various sites are necessary to clarify the taxonomic status of the subgroup. Samples from Cheju island constituted another subgroup, and they should be named as hpodemus cheiuensis. Samples from Wan island composed still another subgroup, and thew seemed to be another population of Apodemus chejuensis: further analvses are needed for the classification of Apodemus cheiuensis. In the last subgroup composed of six of seven samples from Cheongiu and four samples from Haenam, two samples from Cheonsiu and one sample from Haenam were identical in their mitochondrial genotypes, indicating that these striped field mice from Cheongiu and Haenam have close maternal relationship.
