Huia cavitympanum是一种特有的婆罗洲青蛙，是已知的第一种专门发射超声波的两栖动物物种（即，>20 kHz）的语音信号。为了验证这些青蛙使用纯粹的超声波发声进行种内交流的假设，我们对雄性青蛙在其自然叫声部位进行了回放实验。我们发现，青蛙响应增加呼吁广播同种呼吁只包含超声波。该领域的研究补充了电生理记录从听觉中脑和激光多普勒振动计测量鼓膜的响应声刺激。这些测量结果显示，青蛙的听觉系统在高频上有很大的调谐范围，在超声波频率范围内出现峰值灵敏度。结果表明，H. cavitympanum是第一个被描述为纯粹用超声波声音信号交流的非哺乳类脊椎动物。这些数据表明，进一步研究H。cavitympanum和Odorrana tormota（一种产生和检测超声波但不完全发出超声波呼叫的不相关青蛙物种）将为脊椎动物高频通信的机制提供新的见解。
Huia cavitympanum, an endemic Bornean frog, is the first amphibian species known to emit exclusively ultrasonic (i.e., >20 kHz) vocal signals. To test the hypothesis that these frogs use purely ultrasonic vocalizations for intraspecific communication, we performed playback experiments with male frogs in their natural calling sites. We found that the frogs respond with increased calling to broadcasts of conspecific calls containing only ultrasound. The field study was complemented by electrophysiological recordings from the auditory midbrain and by laser Doppler vibrometer measurements of the tympanic membrane's response to acoustic stimulation. These measurements revealed that the frog's auditory system is broadly tuned over high frequencies, with peak sensitivity occurring within the ultrasonic frequency range. Our results demonstrate that H. cavitympanum is the first non-mammalian vertebrate described to communicate with purely ultrasonic acoustic signals. These data suggest that further examination of the similarities and differences in the high-frequency/ultrasonic communication systems of H. cavitympanum and Odorrana tormota, an unrelated frog species that produces and detects ultrasound but does not emit exclusively ultrasonic calls, will afford new insights into the mechanisms underlying vertebrate high-frequency communication.
