摘要: 对喜马拉雅山南坡地区的46种蚤的营养生态位宽度和生态位重叠进行了研究。结果表明,23种蚤只有1种宿主,其营养生态位宽度最窄(B=0),而方指双蚤的营养生态位宽度最大(B=0.6694),其次为斯氏新蚤(B=0.4968).寄生于9种小兽宿主的12种主要蚤种中,尼泊尔古蚤和后厉蚤和窄突厉蚤因其宿主动物以食虫类为主,相互间的营养生态位重叠指数最高。

Abstract: Studies on the trophic niche breadth and overlap of 46 species of flea in the southern slope of the Himalayas Mountains show that there were 23 species of flea only parasitized one kind of host, and their trophic niche breadth was the narrowest(B=0). Amphipsylla quadratedigita had the widest(B=0.6694) trophic niche breadth, and then, Neopaylla stevensi the second(B=0.4968). Among 12 dominant flea species lived on 9 small animal species, Xenodaeria telis, X. angustiproceria and Palaeopsylla tauberi mainly lived on Soriculus nigrescens, a kind of small insectivorous mammal, so the trophic niche overlaps among them were the highest.
