几种啮齿动物食性比较研究

采用笼养饲喂法，野外个体颊囊内含物统计法和胃内含物分析法３种方法，于１９９７年对内蒙古鄂尔多斯沙地中的４种主要啮齿动物（小毛足鼠Ｐｈｏｄｏｐｕｓ ｒｏｂｏｒｏｖｓｋｉｉ、三跳跳鼠Ｄｉｐｕｓ ｓａｇｉｔｔａ、子午沙鼠Ｍｅｒｉｏｎｅｓ ｍｅｒｉｄｉａｎｕｓ和黑线仓鼠Ｃｒｉｃｅｔｕｌｕｓ ｂａｒａｂｅｎｓｉｓ）的食性进行了研究。３种方法得出的结果基本一致，从胃内含物和颊囊内含物分析结果看，小毛足鼠和黑线

Comparative Studies on Food Habits of Several Rodent Species

Food habits were studied for four dominant rodents ( Phodopus roborovskii, Dipus sagitta, Meriones meridianus and Cricetulus barabensis ) inhabiting in Ordos sandland, NeiMongol in 1997. The results obtained by three methods of feeding experiments, analysis of cheek pouch contents, and analysis of stomach contents showed no significant differences basically. Phodopus roborovskii and Cricetulus barabensis feed mainly on various plant seeds and insects according to the analysis of cheek pouch contents and stomach contents; plant seeds are also primary foods of them and high water content green plants are needed to replenish water in feeding experiments. Dipus sagitta feeds on green plants and herbage seeds primarily. The food preference of Meriones meridianus is similar to Dipus sagitta on plants and seeds, while on seeds is similar to Phodopus roborovskii and Cricetulus barabensis.
