Weddell seals exhibit discontinuous variation in their underwater trills.
Male Weddell seals produce loud, long underwater trills when defending breathing holes or groups of females. Mixing of males along the coastline should result in clinal variation in their trills. We examined duration, frequency and waveform measures of trills recorded around Antarctica. Features mea...

| Summary: | Male Weddell seals produce loud, long underwater trills when defending breathing holes or groups of females. Mixing of males along the coastline should result in clinal variation in their trills. We examined duration, frequency and waveform measures of trills recorded around Antarctica. Features measured are present in all trills, thus facilitating multivariate analyses. |
