Variations in advertisement call modulations do not influence vocal interactions in bullfrog choruses

Chorusing male bullfrogs naturally vary the number of modulations within their advertisement call notes. A field playback experiment investigated whether these variations affect males' evoked vocal responses. Vocal responses were quantified manually and automatically by quantifying acoustic ene...

Sumario:Chorusing male bullfrogs naturally vary the number of modulations within their advertisement call notes. A field playback experiment investigated whether these variations affect males' evoked vocal responses. Vocal responses were quantified manually and automatically by quantifying acoustic energy. The numbers of calls, number of notes, latency of response, and detected-note acoustic energy did not vary significantly across playback stimuli for focal males or the entire chorus, suggesting that variations in modulation number do not carry relevant information to males. Future work can determine whether modulation cues may function in sexual selection and affect female response.
