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 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.

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.

한국에 서식하고 있는 붉은쥐속 2 종, 등줄쥐(Apodemus agrarius coreae, A. agrarius chejuensis)와 흰넓적다리 붉은쥐 (A. peninsulae peninsulae)의 염색체 및 형태적 형질의 분석을 하였다. A. agrasius coreae는 작은 형이고, A. agrarius chejuensis 와 A .peninsulae peninsulae 는 큰 형이었다. 또한A. agrarius chejuensis 는 A.peninsule peninsulae 보다도 큰 편이었다. A.peninsulae peninsulae 에 있는 B chromosomes 은 C.-negative 즉 진정염색질임이 밝혀졌다.

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.

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.

Thirty one morphometric characters of striped field mice(Apodemus agrarius) from eight localities in Korea were analyzed by multivariate methods in order to confirm taxonomic status of specimens from Wando island. Two subgroups were recognized: a small-size form from six localities (Mt. Taebaek, Mt. Weolak, Cheongju, Mt. Chiri, Kunsan, and Jin isoland) and a large-size form from Wando island and Cheju island. It is confirmed that the small-size form from six localities is A. a. coreae, as described by Thomas(1908), and that the large-size form from Cheju island is A. a. chejuensis, as named by Johnson and Jones (1955). Furthermore, it is confirmed that large-size specimens from Wando island is and Cheju island. It is confirmed that the small-size form from six localities is A. a coreae, as described by Thomas(1908), and that the large-size form from Cheju island is A. a. chejuensis, as named by Johnson and Jones(1955). Furthermore, it is confirmed that large-size specimens from Wando island is subspecies A. a. chejuensis, as suggested by koh (1989). In future, analyses with specimens from islands in southern coasts are necessary to clarify the taxonomic status of Apodemus agrarius in Korea.

Samples of striped field mice, Apodemus agrarius Pallas, from eight localities in s southwestern islands and coasts in Korea were collected and analyzed together with samples from the mainland and Jeju island. In chromosomal analyses no variation was revealed in karyotypes among samples from Korea. In morphometric analyses samples from Wan and Bogil islands formed a large-size g group (A. agrarius chejuensis) with those from Jeju island, whereas samples from Jin and H Hajo islands formed a small-size group (A. agrarius coreae) with those from the mainland including southwestern coasts It is supposed that small-size population of striped field mice in Wan and Bogil islands w were extinct and replaced by large-szie population of striped field mice immigrated from Jeju island by humans.
