中国43种蛙类鸣声特征数据集

无尾两栖动物的鸣声通常具有物种特异性,了解其鸣声特征信息,是利用生物声学进行物种多样性调查及物种监测的前提。本文汇总、整理了2012–2020年间利用高保真录音设备在野外记录的43种(隶属于7科26属)无尾两栖动物的鸣声数据,以及相应的鸣声采集信息。对音频文件进行降噪处理后,提供了由61个鸣声的波形图及语图组成的鸣声特征数据集。本数据集展示了鸣声的多种时域和频域信息,如单音节或多音节、音节数、音节时长、音节间隔、鸣声时长、主频、基频、谐波等,为我国无尾两栖类的声学研究、物种多样性调查及鸣声监测提供了数据支持。

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

Calls of anuran species (frogs and toads) are generally species-specific. This means that bioacoustics can be used to investigate species diversity and monitor species, but only if the call characteristics are known. In this study, we summarize the call data and sample information of 43 anuran species (from 26 genera in 7 families) recorded in the field with high-fidelity recorders from 2012 to 2020. In addition, we provide a call characteristic dataset with oscillograms and spectrograms of 61 calls (after noise reduction processing). The dataset contains temporal and spectral characteristics of the calls, such as the note number, note duration, inter-note interval, call duration, dominant frequency, fundamental frequency, harmonics, and whether they are monosyllabic or multisyllabic. This dataset is essential for using acoustic techniques to survey species diversity and monitor anuran species in China using their calls.
