A limitation in bioacoustic studies has been the inability to differentiate individual sonic contributions from group-level dynamics. We present a novel application of acoustic camera technology to investigate how individual wood frogs’ calls influence chorus properties, and how variation influences mating opportunities. We recorded mating calls and used playback trials to gauge preference for different chorus types in the laboratory. Males and females preferred chorus playbacks with low variance in dominant frequency. Females preferred choruses with low mean peak frequency. Field studies revealed more egg masses laid in ponds where males chorused with low variance in dominant frequency. We also noted a trend towards more egg masses laid in ponds where males called with low mean frequency. Nearest-neighbour distances influenced call timing (neighbours called in succession) and distances increased with variance in chorus frequency. Results highlight the potential fitness implications of individual-level contributions to a bioacoustic signal produced by groups.

个体对群体合唱动态的贡献会影响林蛙获得交配机会的机会

生物声学研究的一个限制是无法区分个体声波贡献与组级动力学。我们提出了声学相机技术的新应用，以研究个体林蛙的叫声如何影响合唱特性，以及变异如何影响交配机会。我们记录了交配呼叫并使用回放试验来衡量实验室中不同合唱类型的偏好。男性和女性更喜欢主频变化较小的合唱播放。女性更喜欢平均峰值频率较低的合唱。实地研究表明，在雄性合唱的池塘中产卵量更多，主频差异较小。我们还注意到在池塘中产卵的趋势越来越多，雄性以较低的平均频率打电话。最近邻居的距离影响呼叫时间（连续呼叫的邻居），并且距离随着合唱频率的变化而增加。结果突出了个体水平对群体产生的生物声学信号的潜在健康影响。
