摘要
Anurans often have species-specific vocalizations. To quantify and compare the characteristics of anuran calls in Gutianshan National Nature Reserve, Zhejiang Province, we recorded the advertisement calls of eight species belonging to four families （Ranidae, Microhylidae, Megophryidae and Bufonidae） from June to September 2012 using Sony ICD-FX8 IC recorders. All recordings were analyzed using the ＂Praat＂ software. Five acoustics parameters were measured, including temporal traits （call duration, number of notes or pulse number/call） and spectral traits （fundamental frequency, the first three formants and dominant frequency）. The characteristic parameters of Microhyla ornate and Fejervarya limnocharis calls were different as were the calls of some populations of the same species recorded in different regions. The advertisement calls of the eight species were specific. Our study has provided a useful reference for identifying the calls of some common Chinese anurans.
