Dear list members,
I would like to bring to your attention the following recent publication
that might be of interest to some:
Ana Alves, Ricardo Antunes, Anna Bird, Peter L. Tyack, Patrick J. O. Miller,
Frans-Peter A. Lam, Petter H. Kvadsheim. 2014. Vocal matching of naval sonar
signals by long-finned pilot whales (Globicephala melas). Marine Mammal Science.
Abstract:
"Behaviour and sound production of 5 long-finned pilot whale groups were
recorded in 12 sonar experiments conducted in Norway in 2008 and 2009. The
recordings revealed whale calls matching the frequency modulation patterns of
transmitted sonar signals. A contour shape dissimilarity score was calculated
between each sonar signal and the contours of 2556 social calls. For 2 of 12
experiments, which included upsweep and downsweep sonar signals, randomization
tests indicated that the contour shapes of some calls were more similar to the
sonar than expected by chance. Better understanding of acoustic signalling in
this species is essential to estimate the impact of this relevant response to
anthropogenic sound."
