Abstract:In this study, the diet of Eremias multiocellata that captured from Kubuqi Desert, Erdos, Inner Mongolia was investigated by analyzing the food composition in stomach. The prey number and frequency, index of percent similarity, width of tropic ecological niche, overlap of tropic ecological niche, and beneficial coefficient of the food of 85 individuals were assessed. The results showed that E. multiocellata was a kind of omnivorous lizard that mainly fed on insects (more than 41 families, 13 orders and 2 classes), followed by Arachnida and plant seeds. There were no dietary differences between the sexes in E. multiocellata. However, the dietary difference between the juveniles, subadults and adults were significant. The nutritional niche overlap between the sexes was high. Trophic niche breadth and food diversity index were maximum in subadults, while minimum in adults. The general beneficial coefficient was positive, indicating that E. multiocellata ate more pests.
