Although amphibians are highly vocal, they generally emit only a limited number of acoustic communication signals. We report here the extraordinarily rich vocal repertoire of Amolops tormotus, a ranid species in China. These frogs produce countless vocalizations, some of which share features of birdsong or primate calls, e.g., ultrasonic frequency components, multiple upward and downward FM sweeps, and sudden onset and offset of selective harmonic components within a call note. Frame-by-frame video analysis of the frog's calling behavior suggests the presence of two pairs of vocal sacs that may contribute to the remarkable call-note complexity in this species.

尽管两栖动物发声频繁，但它们通常仅发出有限数量的声学通讯信号。我们在此报告中国蛙科物种高山倭蛙异常丰富的发声 repertoire。这些青蛙能发出无数种叫声，其中一些具有鸟鸣或灵长类动物叫声的特征，例如超声波频率成分、多个上下调频扫描以及叫声音符内选择性谐波成分的突然起始和结束。对青蛙鸣叫行为的逐帧视频分析表明，存在两对声囊，这可能是该物种叫声音符显著复杂的原因。本文的电子补充材料可通过位于http://dx.doi.org/10.1007/s00114-002-0335-x的Springer LINK服务器获取。
