Structures of Small Mammal Populations and Communities in Steppe Ecosystems of the Caspian Northwest Coastal Areaand Eastern Mongolia

摘要

The responses of populations and communities of small mammals have been studied under different grazing regimens. It is shown that overgrazing and grazing restriction can have a considerable impact on the population status, demographic structure, andalspecies composition of small mammals in the Caspian northwest coast area (Nogai Steppe) and the steppes of Eastern Mongolia.
