Overview

Bioacoustic study reveals temporal acoustic modulation across social contexts in territorial damselfish, suggesting flexible sound production for defence and courtship.

Key Points

To characterise the acoustic repertoire of the damselfish Stegastes fuscus and determine how sound features vary across agonistic and courtship social contexts.
Recorded wild Stegastes fuscus behaviour using synchronised underwater audio-video systems during territorial defence and courtship interactions.
Measured and statistically compared temporal and spectral acoustic parameters across different behavioural contexts.
Acoustic differences between social contexts were driven primarily by temporal parameters rather than spectral properties.
Courtship calls exhibited longer durations and contained more acoustic pulses than agonistic calls produced during territorial defence.
