摘要: 分析甘肃民勤209只成体和43只幼体密点麻蜥胃含物表明,密点麻蜥是以动物性食物为主的杂食性动物,主要以甲虫和白刺果为食.成体出蛰后即开始强烈摄自,摄食率均在83%以上.食性季节性变化显着,春季仅以动物为食,夏季动物性和植物性食物各半,秋季植物性食物占1/3.食物种类多样性和营养生态位宽度随体形增大而增加.

Abstract: Food composition in stomaches of 209 adults and 43 juveniles of Eremiqs multiocellata in Minqin area of Gansu Province is analyzed. The results show that Eremias multiocellata is a kind of omnivorous animal which mainly feeds on beetles and Nitraria fruits. After its dormancy, this animal begins to strongly ingest, its ingesting rate being more than 83%.It has an obvious seasonal variation of feeding habit, i.e. only animals are ingested inspring, half of animal and plant in summer, and third of plant in autumn. The diversityof food and the breadth of trophic niche are increased with its increasing size growth.

Key words: Eremias multiocellata, Feeding habit, Ingestion, Seasonal variation
