A dataset on the call characteristics of 43 anuran species in China

Calls of anuran species are generally species-specific, and understanding the call characteristic is the basis of using bioacoustics to investigate species diversity and monitor species. In this study, we summarized the call data of 43 anuran species recorded by high-fidelity recorder in the field during 2012-2020, and provided a call characteristic dataset composed of oscillogram and spectrogram of 61 calls after noise reduction processing of audio files. In addition, the data description file contained a species list and sample information. The dataset comprised a variety of temporal and spectral characteristic of calls, such as monosyllabic/polysyllabic, note number, call duration, inter-note interval, call duration, dominant frequency, fundamental frequency, and harmonics, etc., providing support for the acoustic research, species diversity survey and call monitoring of anuran species in China.

无尾目物种的鸣叫声通常具有物种特异性，对鸣叫特性的理解是运用生物声学方法探究物种多样性和监测物种的基础。在本研究中，我们总结了2012-2020年间使用高保真录音设备在野外采集的43种无尾目物种的鸣叫数据，并提供了经过音频文件降噪处理后的61个鸣叫声的波形图和频谱图构成的鸣叫特性数据集。此外，数据描述文件包含了物种列表和样本信息。该数据集包含了鸣叫的多种时域和频域特性，如单音节/多音节、音符数量、鸣叫时长、音符间间隔、鸣叫时长、主频率、基频和谐波等，为我国无尾目物种的声学研究、物种多样性调查和鸣叫监测提供了有力支持。
