Horizontal and Elevational Distributions ofApodemus peninsulae,A. dracoandA. latronum

Abstract

Abstract. Horizontal and elevational distributions of Apodemus peninsulae, A. draco and A. latronum are illustrated. A total of 1,355 museum specimens were identified by their cranial measurements and the size of t7 cusp on the first upper molar in 180 localities of Russia, Mongolia, China, Taiwan, Korea, Myanmar, India and Japan. Apodemus peninsulae belonged to “the northern pattern”, A. draco to “the southern China pattern” with “the Hengduan Shan pattern”, and A. latronum to “the Hengduan Shan pattern”, respectively, among nine distributional patterns reported previously. The distribution of A. latronum did not extend eastward from the Min Jiang along 104°E, and southward from the Jinsha Jiang between 101°E and 104°E in eastern and southeastern Sichuan, China. Relative compositions of elevational occurrence where the three species of Apodemus showed a gradual decrease ranging from 500 m to 3,500 m classes in A. peninsulae, the greatest concentration in the 2,000–2,500 m classes between 500 m and 4,500 ...
