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 climatic conditions of Central Asia.
本综述是关于社会田鼠生态与社会行为的已发表数据汇编。野外研究表明，这些田鼠以家庭群体形式生活，每个群体由1只成年雄性、1或2只繁殖雌性及其后代（1或2窝幼崽）组成。社会田鼠全年都有繁殖能力，但在干旱地区，田鼠的繁殖具有季节性。该物种的交配系统可定义为行为上的一夫一妻制。空间利用系统的一个典型特征是领地性，其特点是相邻繁殖对以及家庭群体之间的关系存在位置依赖性优势。家庭群体社会组织可定义为没有主导等级制度的稳定关系。社会田鼠在保卫领地、建造洞穴、挖掘地下隧道、维护巢穴和养育幼崽方面相互合作。在中亚极端气候条件下，合作似乎提高了该物种家庭群体的存活率。
