Geographic variations in underwater male Weddell seal Trills suggest breeding area fidelity
Entry ID:
ASAC_1132-2
Summary
Abstract:
Adult Weddell seals (Leptonychotes weddellii) exhibit site fidelity to where they first breed but juveniles, and perhaps transient adult males, may disperse from their natal location. If there is mixing between adjacent breeding
groups, we would expect that common vocalisations would exhibit clinal patterns. Underwater Trill vocalisations of male Weddell seals at Mawson, Davis, Casey, ...

Quality
The data are measurements relating to the acoustic properties of Weddell seal underwater Trill vocalisations. The measures include a broad classification of the waveform (sinusoidal, frequency modulated or pulsed)at the start and end of the Trill, the duration (milliseconds) and the frequency (Hz) at the beginning, end and at 9 other equally spaced intervals along the call. Trills were recorded in different years from 6 locations around Antarctica. Only Trill vocalisations were analysed because they are only made by males and they have a known territorial defence function.
