摘　　要：We recorded and described the calls and acoustic characteristics of the male tiger frog,Hoplobatrachus rugulosus,in an artificial pond during mating season.Spectral and temporal call parameters,along with call intensity were analyzed.Three harmonics were distinguishable from the spectrogram.Four patterns of dominant frequency were found in calls produced late at night,i.e,3 patterns in the first harmonic（located in 500 Hz section,700 Hz section,and 800 Hz section respectively） and 1 in the second harmonic（located in 1 800 Hz section）.Call duration,call duty cycle,call intensity,and pulse rate were highly variable among different patterns of dominant frequency.These call properties could provide valuable evidence for further ecological study of this species.对交配季节虎纹蛙求偶鸣叫进行录制和特征分析。分析结果表明,虎纹蛙求偶鸣叫主要集中在晚上,求偶鸣叫声音主要含有3个鸣叫谐波,鸣叫主频率共有4种类型,即在第一谐波上有3个主频率段,分别为500、700和800Hz段,在第二谐波上有1个主频率段,即1800Hz段。鸣叫时程(call duration)、能环率(call dutycycle)、声强(call intensity)和鸣叫脉冲率(pulse rate)在4种主频率中变化很大。这些鸣叫参数特征的分析将对虎纹蛙生理生态学的进一步研究提供有价值的基础数据。
