摘要
The present review is a compilation of the published data on the ecology and social behavior of the social vole.Field studies provide evidence that these voles live in family groups consisting of 1 adult male,1 or 2 breeding females,and their offspring(1 or 2 litters).The social vole is capable of year-round reproduction,but in arid regions,the voles demonstrate seasonality in breeding.The mating system of this species may be defined as behavioral monogamy.A typical feature of the space use system is territoriality characterized by a locus-dependent dominance in relationships between neighboring breeding pairs as well as family groups.The family group social organization may be defined as consistent relationships without a dominant hierarchy.Social voles are cooperative in defending their territories,constructing burrows,digging underground tunnels,maintaining nests,and raising young.Cooperation appears to enhance the survival of family groups of this species under the extreme climaticconditionsof Central Asia.
