We present the first data on the vocalizations of large odorous frogs (Odorrana graminea, previously Odorrana livida), from southern China. The males produce diverse broadband signals most of which contain ultrasonic harmonics. Six basic call-types were identified based on the number of call notes, fundamental frequency, call/note duration, frequency modulation patterns and spectral composition. O. graminea is one of only a few non-mammalian vertebrates able to detect ultrasound, but its tympanic membranes are not recessed. These results should stimulate further studies to provide new insights into the mechanisms underlying high-frequency communication in anurans.
我们呈现了来自中国南方的大型臭蛙（Odorrana graminea，之前被称为 Odorrana livida）的叫声的第一组数据。雄性产生多样化的宽带信号，其中大多数包含超声波谐波。根据叫声音符的数量、基频、叫声/音符持续时间、频率调制模式和光谱组成，确定了六种基本叫声类型。O. graminea 是少数几种能够检测超声波的非哺乳动物脊椎动物之一，但它的鼓膜没有凹陷。这些结果应该会刺激进一步的研究，为理解两栖动物高频通讯的机制提供新的见解。
