  • 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.

  • 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.

  • This study was conducted four ecological survey of field mice of Mt. Chuisuh in Yangsan City, Kyungnam from June, 2000 to March, 2001 for the understanding of field mice damage to forest. The results are obtained as follows. 1. The species of field mice collected were Apodemus agrarius, Apodemus peninsulae and Eothenomys regulus, and Crocidura suaveolens of insectvore. 2. The total collecting rate were 8.1% collected 61 individuals of field mice from 758 trap. 3. The rate among the 61 field mice collected were 45.9% in Apodemus agrarius, 29.5% in Eothenomys regulus, 19.7% in Apodemus peninsulae, and 4.9% in Crocidura suaveolens. 4. The constitution of weight of field mice was 16-51.9g in Apodemus agrarius, 12-25.9g in Apodemus peninsulae, 16-45.9g in Eothenomys regulus, and 12-15.9g in Crocidura suaveolens. 5. The sex ratio of field mice was 48.0% : 52.0% in Apodemus agrarius, 50.0% : 50.0% in Apodemus peninsulae, 55.6% : 44.4% in Eothenomys regulus, and 66.7% : 33.3% in Crocidura suaveolens. 6. The average body lengh was 104.33mm in Eothenomys regulus, 96.04mm in Apodemus agrarius, 94.50mm in Apodemus peninsulae, and 76.33mm in Crocidura suaveolens. 7. The average tail lengh was 92.75mm in Apodemus peninsulae, 80.65mm in Apodemus agrarius, 41.0mm in Crocidura suaveolens, and 40.33mm in Eothenomys regulus. 8. The breeding period of field mice in Mt. Chuisuh presumes from about the early of March to end of October. Specially, The Eothenomys regulus was ascertained the breeding period in December, discovered first time in korea through this experimental study. 9. The average litter size of field mice was 4.5 in Apodemus agrarius, 4.7 in Apodemus peninsulae, and 3.4 in Eothenomys regulus.

  • 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.

  • 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.

  • 문경산 흰 넓적다리 붉은 쥐, Apodemus peninsulae peninsulae, 의 염색체 핵형 분석과 단변량 및 다변량분석방법들을 사용한 등줄쥐, Apodemus agrarius coreae, 와의 형태적 형질의 비교를 하였다. 흰 넓적다리 붉은 쥐의 염색체수는 2n=50-54R지 수적 변이를 보였다. 차단부 염색체의 수는 48개로 개체간에 일정하였으나 , 중부 염색체의 수는 2-6개의 변이가 나타났다. 형태적 형질의 분석결과는 등줄쥐보다 흰 넓적다리 붉은 쥐가 크다고 판정되었으며 가장 구별이 잘 되는 경구개의 길이였다.
