| 摘 要： | 动物在强噪声背景条件下进行声通讯，必须采用特殊的策略。一小群脊椎动物，如蝙蝠、海豚与鲸，及少数啮齿类用超声信号通讯。本研究首次证实，凹耳蛙是第一个能产生并检测超声信号的非哺乳类脊椎动物。凹耳蛙进化超声通讯的能力的研究，不仅为理解为什么人类有耳道提供暗示，有助于了解动物听觉系统的进化，并对开发仿生技术有重要启示。

| Abstract: | Animals have special solution to the problem of communication in high levels of background noise. A small group of vertebrates (bats, dolphins and whales, and some rodents) that use ultrasound for communication. Our research first demonstrated that the concave-eared torrent frog is the first non-mammalian vertebrate found to be capable of producing and detecting ultrasounds for communication. This study may provide a clue for understanding why humans have ear canals and how animals auditory systems have evolved, and inspire in developing bionic tecnology for improving hearing in noise. |
