摘　　要：本文研究了保加利亚北部地区的匈牙利小家鼠在繁殖期的空间关系和分布。这种动物最普遍的空间关系是一雄一雌,也观察到两个或三个雄鼠与一个雌鼠、一个雄鼠与两个或三个雌鼠的组织形式。很少观察到雌性的社群小组。雌鼠之间的巢区没有发现重叠。一般雄鼠的巢区大于雌鼠。有一半雄鼠的巢区与一个雌鼠的巢区相重叠,其他的雄鼠与两个成年雌鼠的巢区相重叠。这些结果表明,匈牙利小家鼠具有多变的社群繁殖婚配体制,即单配制和多配制共存。比较普遍的一雄一雌的配对形式和雌性的独居特性,以及雌性之间巢区的相对独立性,表明单配制是该物种的主要婚配体制。I studied the spatial associations and distribution of mound-building mice Mus spicilegus Petenyi during the breeding period in northern Bulgaria. The most frequent spatial association observed was between a single male and a female. Other associations between two or three males, and between a male and two or three females were also observed. Female social groups were seldom observed. Home ranges of females were exclusive. Male home ranges were larger than those of females. Home ranges of about half of the males overlapped home ranges of one female; the remaining males had home ranges that overlapped home ranges of two adult females. These results suggest that M. spicilegus has a variable socioreproductive mating system that is either monogamous or polygynons. The predominance of male-female pairs and solitary females, as well as the exclusive home ranges of females, suggests that monogamy is the preferred mating system.
