我们描述了与日本田鼠 (Microtus montebelli) 生殖生物学相关的特征。与迄今为止检查的其他田鼠物种相比，日本田鼠生长得更快，并表现出最偏雄性的两性二态性，雄性的睾丸相对较小，表明一夫多妻制的交配系统。因此，我们得出的结论是，该物种是一夫多妻制的，可能是兼性一夫一妻制的交配类型，其中物种表现出结合了多个系统元素的社会模式。
We describe characteristics related to the reproductive biology of the Japanese field vole, Microtus montebelli . In comparison with the other species of Microtus examined to date, Japanese field voles grew more rapidly and exhibited the most male-biased sexual dimorphism, with males having relatively small testes, indicative of a polygynous mating system. Thus, we conclude that this species is polygynous, possibly with the type of facultatively monogamous mating in which species show social patterns that combine elements of several systems.
