雌性布氏田鼠对雄鼠气味的辨别

通过雌性布氏田导其配偶和陌生雄鼠气味的辨别实验，以及无交配经历的成年雌鼠对社会等级不同的陌生雄鼠气的辨别实验发现，有生育经历的雌鼠对陌生雄鼠气味的探究行为明显多于对配偶气味的控究，但雌鼠在配偶雄鼠气味周围的停留时间、自身修饰行为和何处行为的发生频次和持续地陌生雄鼠，没有交配经历的雌鼠对处于从鼠地位的雄性个体气味探究行为多于对优势雄性的控究，而其他行为表现没有明显差异。表明，雌性布氏田鼠可以利用气味

DISCRIMINATION OF MALE INDIVIDUAL SCENT BY FEMALE BRANDT'S VOLE (MICROTUS BRANDTI)

The ability to discriminate different male scents by female Brandt's voles, Mcrotus brandti was studied. Female voles presented more social investigation on novel male odours than the spouse. In the odour choice experiment, females spent more time on self-grooming, resting, and staying in the box with spouse substrate while they avoided the odour of unfamiliar male. Virgin females sniffed and licked to the woodshavings of the subordinate more than that of the dominant male, which indicated that female Brandt's vole had the ability to discriminate individual scents, thus to discriminate different males. It suggested that female voles had sex faithful characteristics in the laboratory paired bond. Such characteristics helped the breeding females to raise their young and to increase breeding success. The preference of odour choice by virginal female gave some hints that Brandt's vole is a polygamous species.
