Popis: The progression of tall-grass steppes has caused a consequent reduction in the abundance of the little ground squirrel. By the beginning of this century, its population had fallen to zero and was not compensated by other rodent species’ biomass. The little ground squirrel is a biocenotically valuable species for a semidesert terrain, since it participates in the latter’s pedogenesis and is a food source for the steppe eagle. Thus, its disappearance would threaten to significantly disturb the structure of the biocenosis.
