自由生活橙腹田鼠的社会组织和婚配制度(英文)

Social organizaion and maing sysem of free-living prairie voles Microus ochrogaser: a review

在美国伊利诺伊州中东部地区对橙腹田鼠(Microtus ochrogaster) 进行的广泛研究基础上, 我们对该鼠的社会组织和婚配制度进行了总结。橙腹田鼠的基本社会组织由最初的雌雄配偶或者单一的雌鼠(常为一对配偶的幸存者) 与留居的后代和非亲缘成体的同居群组成。留居的后代占了原始繁殖单位之外的70%。另外, 直到至少两个留居后代达到成年后, 多数(80%) 的非亲缘个体才加入家族群。因此, 同居群的形成是以高水平的留居为基础的。雌雄配偶表现出与行为单配制有关的特征, 包括共享一个巢穴和家域, 雄性保卫配偶, 以及双亲行为(修饰, 拥抱和衔回幼鼠)。同居群的成员也保卫领域。
