Abstract

Four external and 27 cranial characters of Korean field mice (Apodemus peninsulae) from nine regions in China and Korea, representing three subspecies, were analyzed by multivariate methods. Four size-forms were recognized a largest-size form Mt. Weolak and Yeoncheon in Korea (= subspecies peninsulae) and Kirin and Heilung in China (= subspecies praetor), a large-size form from Inner Mongolia in China (= subspecies praetor) and Sanxi and Sandong in China (= subspecies sowerbyi), a middle-size form from Beijing in China (= subspecies sowerbyi), and a small-size form from Xinjiang in China (= subspecies sowerbyi). Although Corbet (1978) recognized only two subspecies in A. peninsulae, subspecies peninsulae and sowerbyi, within its distributional range in the continent of Asia, it was revealed in this study with morphometric characters that A. peninsulae could not be classified simply into two subspecies, because subspecies praetor and subspecies sowerbyi formed the large-size form and because subspecies sowerbyi was so diverse in its morphology as to be composed of three size-forms. Further analyses with the samples from other regions of China and Russia seem to be necessary to clarify the taxonomy of A. peninsulae.

중국과 한국에 서식하는 흰넓적다리붉은쥐(Apodemus Peninsulae) 3아종의 표본들의 4개 외부형질과 27개 두골형질들을 다변량통계 방법으로 분석하였다. 4개형(form)으로 나뉘 어졌는데, 한국의 월악산과 연천의 아종 peninsulae와 중국의 길림과 흑룡성의 아종 praetor 는 가장 큰 형이며, 중국 내몽고의 아종 praetor와 중국 산서와 산동성의 아종 sowerbyi는 큰형이고, 중국 북경의 아종 sowerbyi는 중간 형이며, 중국 신강성의 아종 sowerbyi는 작은 형이었다. Corbet(1978)는 아시아 대륙내의 흰넓적다리붉은쥐의 분포범위에서는 2아종 (peninsulae and sowerbyi)으로 분류된다고 하였지만, 형태적 형질을 이용한 본 연구에서 아 종 praetor와 peninsulae가 큰 형이었고, 아종 sowerbyi는 3개의 형태로 나뉠 정도로 다양했 으므로, 단지 2아종으로만 분류할 수가 없음이 밝혀졌다. 중국과 러시아의 다른 표본들을 포 함한 계속되는 연구가 본 종의 확실한 분류의 완성을 위해서 필요하다.
