The social context of individual foraging behaviour in long-finned pilot whales (Globicephala melas)Visser, F. (author), Miller, P.J.O. (author), Antunes, R.N. (author), Oudejans, M.G. (author), Mackenzie, M.L. (author), Aoki, K. (author), Lam, F.P.A. (author), Kvadsheim, P.H. (author), Huisman, J. (author), Tyack, P.L. (author)Long-finned pilot whales (Globicephala melas) are highly social cetaceans that live in matrilineal groups and acquire their prey during deep foraging dives. We tagged individual pilot whales to record their diving behaviour. To describe the social context of this individual behaviour, the tag data were matched with surface observations at the...article 2014

(author), Lam, F.P.A. (author), Ainslie, M.A. (author), Thomas, L. (author)Eight experimentally controlled exposures to 1−2 kHz or 6−7 kHz sonar signals were conducted with four killer whale groups. The source level and proximity of the source were increased during each exposure in order to reveal response thresholds. Detailed inspection of movements during each exposure session revealed sustained changes in speed and...article 2014
