Taxonomic Stautus of Striped Field Mice(Mammalia: Rodenita) from Wando Island, Korea

한국 완도에 서식하고 있는 등줄쥐(포유강: 설치목)의 분류학적 위치

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.

완도산 등줄쥐의 분류학적 위치를 재검토하기 위해, 한국의 8개 지역에서 채집한 등줄쥐(Apodemus agrarius)의 31개 형태적 형질들을 다변량분석방법으로 분석하였다. 두 군으로 나누어 졌는데, 6개 지역(태백산, 월악산, 청주, 지리산, 군산, 진도)의 작은 형과 2개 지역(완도, 제주도)의 큰 형이었다. 6개 지역의 작은 형은 Thomas(1908)가 밝힌 대로 A. a. coreae이고, 제주도 지역의 큰 형은 Johnson과 Jones(1955)이 이 기재한 대로 A. a. chejuensis임이 확이되었다. 뿐만 아니라, 완도의 큰형은 Joh(1989)가 제안한대로 A. a. chejuensis임도 확인되었다.
