Abstract: The proceeding of mating system studies in voles were reviewed, based on the ecological patterns of social organization factors affecting mate choice, sexual dimorphisms male ejaculatory capacity neuroendocrinological mechanism for social pair bonding. Various study paradigms of mating systems in voles were also introduced, with methodological aspects including of ecology comparative psychology physiology and neurobiology. First, ecologists have discovered that the voles represent a group of closely related species with contrasting patterns of social organization and provide integrate diversity of mating systems: monogamy polygyny polyandry and promiscuity. Second, ethologists,using approaches of comparative psychology have established mating systems as association with mate choices among inldividuals by familiarity,social dominant rank, and recency of mating by potential mate.The association was limited to a comparison between monogamous and promiscuous vole species. And the association based onthe dichotomous comparison has not beenexamined among monogamous ,polygynous and promiscuous vole species. The dichotomy was so prevailing in the past that the research of relationship between mate choice and mating systems in voles was incomprehensive.Thrid, neurobiologist,collaborating with behavioral ecologists ,has found that prairie vole is an excellect model system for the neurobiological bases of pair bonding in monogamy, suggesting that two neuropeptide hormones,vasopressin and oxytocin ,and adrenal glucocorticoid with their pathways in the central nervous system appear to influence pair bonding and various aspects affiliation in monogamous voles, Exactly how these hormones interact and integrally affect social behavior remains to be fined, as do theirroles in the non-monogamousvole species.
