Abstract
From June to July in 2006 and May in 2011,the faunas and distribution of small mammals (Insectivora,Rodentia and Ochotonidae) in the Erlang Mountains was surveyed.We sampled small mammals using kill traps at five sites at elevations varying from 1 800 to 3 437 m,Within each site,we sampled along separate quadrates in different vegetation.In 4 550 trap nights,we captured 300 individuals representing 28 species,15 genera,6 families and 3 orders.There were 19 species on the east slope,all of which belonged to the Oriental realm.There were 17 species on the west slope,2 of which belonged to the Palaearctic realm,14 of which belonged to the Oriental realm,and 1 of which is widely distributed.The Himalayan-Hengduan mountains type is preponderant on both the east and the west slopes.The small mammals' species and quantity are the most in mountainside both the east and the west slope.The small mammals' combination and dominant species are different at different elevations and in different vegetation.关键词
