| 摘 要： | 本文研究了非繁殖期成年雄性布氏四鼠对陌生群体气味、本群体气味的社会探究行为和尿标记行为，探讨了布氏四鼠利用气味信号进行群体辨别的能力。在对熟悉相的辨别实验中，雄鼠对陌生群体气昧的社会探究和尿标记行为明显多于本群体气味和对照组，优势个体的探究和尿标记行为显著高于从属个体。实验结果表明：布氏田鼠具有对群体气味的辨别能力；在巢垫物中存在用于群体识别的化学通讯成分，优势鼠的气味标记可能在种内群体间的嗅觉通讯中起着重要的作用。

| Abstract: | In order to study the capability of group discrimination with odour cues of Brandt'vole(Microtus brandti),social investigation and urine-marking behaviour on umfamiliar and own group odour by male adult were studied during nonbreeding period.In the habituation-discrimination experiment,male voles investigated scents from substrate of unfamiliar group more than those of own group and control,and deposited morel urine marks.Dominate males showed more investigation and urine-markins significantly than subordinates. It is indicated that Brandt' vole have the ability to discriminate group scents, factors for group discrimination exist in the substrate,and it also suggest that scent marks of dominate play important cues in conspecific group olfactory communication. |
