摘　　要：利用监控录像以及特定行为记录的方法,研究了雄性等级对布氏田鼠气味选择和个体选择的影响。结果表明不论是气味选择还是个体选择,雌鼠动情状态不影响对雄鼠的选择频次,但是动情雌鼠在自我修饰行为频次上高于非动情雌鼠。此外,在气味和个体选择的优先权方面,动情雌鼠更多的优先选择优势雄鼠的气味和个体并与之交配,而非动情雌鼠更多的先选择从属雄鼠的气味和个体。总之,不论是气味选择还是个体选择,布氏田鼠不仅受到被选择雄鼠的地位影响,还与雌鼠的生理状态有关。By using monitor and special behaviors recording method, a laboratory study was made on the influence of male hierarchy on female choice of L. brandtii. The results showed that there was no significant difference in odor preference and individual preference, no matter the female vole was on estrous or not. The estrous female took on more self-grooming behavior than the non- estrous female in both the odor preference and the individual preference experiments. On the selection priority, estrous female would first select the odor or individual of dominant male and mate with it, while non-estrous female would first select the odor or individual of subordinate male. The female choice of L. bramdtii was not only influenced by male hierarchy, but also influenced by the physiological status of female vole.
