声通讯对动物的生存至关重要。无尾两栖类动物(蛙与蟾蜍)在进化上处于鱼类与羊膜类动物的中间,是最先用声音进行交流的四足动物之一。无尾两栖动物的叫声种类较少、形式固定,而其听觉系统又与其他脊椎动物具有诸多类似的特点;所以无尾两栖类,特别是蛙类是研究动物声通讯及动物听觉系统结构、功能与进化的重要模式动物。 研究表明,绝大多数蛙叫声的频率范围在100Hz至5-8kHz之间,它们主要进行低频声通讯。Narins等于2004年发现栖息于中国安徽省黄山桃花溪的雄凹耳蛙(Odorranatormota)的叫声成分中含有超声组分。随后的声音回放实验证明雄凹耳蛙可以发出并检测人耳听不见的超声组分(≥20kHz)...Acoustic communication plays an important role in the lives of a wide variety of animals. Anuran amphibians, such as frogs and toads, are considered to be intermediate between fishes and amniote vertebrates and are among the first tetrapods to communicate acoustically. Anurans typically have small, highly stereotyped vocal repertoires, and the salient features of their calls are often well charact...学位:理学硕士院系专业:医学院基础医学系_微生物学学号:2452009115300
