Partitioning of vegetative trophic resources in the rodent community in the Terek-Kuma Lowland in the Republic of Daghestan

详细

We have studied the quantitative and qualitative diet features of the rodent species in arid conditions of the Terek-Kuma Lowland in the Republic of Daghestan. We have determined the species composition, proportion, and diversity of food resources in the diets of the studied rodent species. The diet of rodents consists of various plants species. For example, the diet of Meriones tamariscinus consists of 29 plant species; M. meridianus, 40 species; Cricetulus migratorius, 26 species; Sylvaemus fulvipectus, 34 species; and Mus musculus, 30 species. The share of exclusively consumed plant species did not exceed 10% of the total amount of food. All pairs of rodent species have low or medium rate of diet overlapping.
