摘　　要：雄蛙鸣声传递招揽、警告、攻击、炫耀、求偶、种间识别等信息,对其繁殖起重要作用。2023年5—7月,收集了昆明呈贡区滇蛙(Nidirana pleuraden)的204个清晰鸣声片段和21天昼夜鸣声数据。结果表明:6月滇蛙的日鸣声数量显著高于5月和7月;鸣叫高峰期为19:00—翌日04:00;不同群鸣期广告鸣声的主频和音节时长无显著差异,基频、音节间隔、音节数量、脉冲速率和鸣声时长均存在极显著差异(P<0.01)。群鸣高峰期,竞争鸣声的脉冲速率极显著低于低峰期,音节间隔极显著高于低峰期,其余5个参数无差异;遭遇鸣声的鸣声时长更低(P<0.05),其余6个参数无显著差异。滇蛙的繁殖盛期为6月;鸣叫行为具有昼夜节律;滇蛙的广告、竞争和遭遇鸣声特征受群鸣强度的影响,滇蛙在群鸣高峰期调整广告鸣声参数,采取提升鸣声基频、音节数量和鸣声时长并降低音节间隔和脉冲速率的策略提升了性吸引力。通过发出高脉冲速率和短音节间隔的竞争鸣声和鸣声时长更长的遭遇鸣声提升了雄-雄竞争中获胜的概率。The calls of male frogs convey information such as solicitation,warning,attack,showing off,courtship,and interspecific recognition,and play an important role in their reproduction.We collected 204 clear segments of calls and 21 days of diurnal calls of Nidirana pleuraden in Chenggong district,Kunming from May to July,2023.The daily number of calls of N.pleuraden was significantly higher(P<0.01)in June than that in May and July.The peak calling period was 19:00 until the next day 04:00.There were no significant differences in dominant frequency and syllable duration of advertisement calls in different chorus periods,but highly significant differences in fundamental frequency,syllable interval,number of syllables,pulse rate,and call duration(P<0.01).At the peak of chorus,the pulse rate of competitive calls was lower(P<0.01),the syllable interval was higher(P<0.01),and there was no difference in the remaining five parameters.At the peak of chorus,the duration of encounter calls was lower(P<0.05),and there was no difference in the remaining six parameters.N.pleuraden had a peak breeding season in June.The calling behavior had a diurnal rhythm.The advertisement,competitive and encounter calls of N.pleuraden were affected by the intensity of chorus.N.pleuraden adjusted the advertisement call parameters during the peak of chorus,and adopted the strategy of increasing the fundamental frequency,number of syllables and duration of calls and decreasing the syllable interval and pulse rate to enhance the sexual attractiveness.The probability of winning in male-male competition was enhanced by producing competitive calls with high pulse rates and short syllable intervals,and encounter calls with longer duration.
