Dear colleagues, We are pleased to share the publication of our open access paper on occurrence of pilot whales and killer whales around Iceland and their interspecific interactions.
Selbmann A, Basran CJ, Bertulli CG, Hudson T, Mrusczok, M-T, Rasmussen MH, Rempel JN, Scott J, Svavarsson J, Wensveen PJ, Whittaker M, Samarra FIP (2022) Occurrence of long-finned pilot whales (Globicephala melas) and killer whales (Orcinus orca) in Icelandic coastal waters and their interspecific interactions. Acta Ethologica. https://doi.org/10.1007/s10211-022-00394-1 <https://doi.org/10.1007/s10211-022-00394-1> Abstract Long-finned pilot whales and killer whales are widelystudy period but killer whale occurrence showed no noticeable changes. Long-finned pilot whales were sighted often in the areas that were also frequented by killer whales and interspecific interactions were commonly observed when both species co-occurred. Interactions appeared to be antagonistic, with killer whales often avoiding long-finned pilot whales and sometimes fleeing at high speed, similar to what has been described elsewhere in the North Atlantic. In the majority of interactions observed (68%), killer whales avoided long-finned pilot whales by moving away, but in 28% avoidance was at high speed with both species porpoising. This variability in the type of behavioural responses indicates that interactions may be more complex than previously described. We discuss regional trends in long-finned pilot whale and killer whale sightings and potential drivers of the observed interactions.
