  • 발행 : 1999.10.01

초록

동아시아의 한국과 중국에 살고 있는 붉은쥐속 (Apodemus) 5종 (A. agrarius, A. chevrieri, A. draco, A. latronum 및 A. peninsulae)의 표본들을 31개 외부 및 두골형질들의 수리분류학적 연구에 사용하였다. 2군과 각 군내의 8아군 [I; 큰 형; (A. agrarius chejuensis), (A. chevrieri), (A. draco orestes와 A. latronum) 및 (A. peninsulae peninsulae와 A. p. preator)], [ll; 작은형; (A. agrarius coreae), (A. agrarius manchuricus, A. a. ningpoensis 및 A. a. pallidior), (A. draco draco) 및 (A. peninsulae sowerbyi)]이 형성되었다. 형태형질의 분석에서 얻은 결론은 다음과 같다: 1) 형태형질들은 붉은쥐속 Apodemus내의 2아속 (Apodemus 와 Alsomys)을 구분하는 데에 유효하지 않다. 2) A. draco와 A. latronum가 동일한 종인지의 결정을 위한 계속적인 연구가 필요하다. 3) A. a. chejuensis는 본 연구에서 분석한 붉은쥐속 5종중에서 형태적 형질에서 가장 크기가 크다. 뿐만 아니라, 다음 사실들이 확인되었다 : 1) A. agrarius, A. chevrieri 및 A. peninsulae는 독특한 종들이다. 2) A. draco와 A.latronum는 흰넓적다리붉은쥐 A. peninsulae와 동종이 아니다. 3) 등줄쥐 A.agrarius의 3형(큰형, 중간형 및 작은형)은 3아종 [(A. a. chejuensis), (A. agrarius coreae) 및 ( A. a. manchuricus와 A. a. pallidior를 포함하는 A. a. ningpoensis]으로 구분된다. 4) A. draco draco와 A. draco orestes는 독특한 아종이다. 5) A. peninsulae peninsulae (A. p. preator포함)와 A. p. sowerbyi는 독특한 아종이다.

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.
