摘　　要：实验室内观察了布氏田鼠雄性个体之间在3种不同社群条件下(社群1:2只雄鼠;社群2:2只雄鼠与1只非动情雌鼠,社群3:2只雄鼠与1只动情雌鼠)的相互行为,结果显示:(1)在嗅闻行为上,不论优势雄鼠还是从属雄鼠在3组间都存在显著差异,它们的嗅闻频次都是在社群3中最少、在社群2中居中,在社群1中嗅闻频次最多;(2)在攻击行为频次上,不论是优势雄鼠还是从属雄鼠在3组中都不存在显著差异;(3)在上跳频次上,优势雄鼠在各组间存在显著差异,从属雄鼠在各组间不存在显著差异;(4)在自我修饰行为频次上,不论是优势雄鼠还是从属雄鼠,在3组之间不存在显著差异;(5)在相互友好行为上,3组间存在显著差异。其中社群2中的雄性之间的友好行为频次最高,社群3中次之,社群1中最低。结果表明,雄性之间的攻击行为并不因为雌性的存在而增强,反而会可能减少,我们推测这可能因为雄性要花费更多的时间用于社群探究和交配,从而减少了雄性之间的斗争。We tested the hypothesis that agonistic behavior between male Brandt＇ s voles （Lasiopodomys brandtii） should increase and amicable behavior should decrease when male voles are competing for female voles. Three different groupings of voles were observed in the laboratory. Grouping 1 - two males; grouping 2 - two males with one non-estrous female; Grouping 3 - two males with one estrous female. The results were （ 1 ） For both dominant and subordinate males the frequency of sniffing behavior was highest in grouping 1, then in grouping 2 and lowest in grouping 3. （2） The dominant male attacked the subordinate male most frequently in grouping 1, then in grouping 2 and least frequently in grouping 3. （3） The frequency of jumping behavior and self-grooming behavior of males was the same in all groups. （4） Amicable behavior was highest in grouping 2, then in grouping 3 and lowest in grouping 1. Hence, contrary to the hypothesis agonistic behavior decreased and amicable behavior increased when male voles were competing for female voles.
