About this talk:
Killer whale call repertoires can provide information on social connections among groups and populations. Killer whales in Iceland and Norway exhibit similar ecology and behavior, are genetically related, and are presumed to have been in contact before the collapse of the Atlanto-Scandian herring stock in the 1960s. However, photo-identification suggests no recent movements between Iceland and Norway but regular movement between Iceland and Shetland. We used acoustic recordings collected in Iceland, Norway, and Shetland to undertake a comprehensive comparison of the call repertoires of Northeast Atlantic killer whales. Time and frequency parameters of calls from Iceland and Norway were relatively similar but no call type matches were confirmed between Iceland and Norway or Shetland and Norway. Three call types matched between Iceland and Shetland. Therefore, these findings agree with what is currently known of the movement patterns of these whales but argue against past contact between Icelandic and Norwegian killer whales, since call repertoires are thought to be maintained over time.
About the presenter:
Anna Selbmann is currently a PhD student at the University of Iceland investigating killer whale acoustic behaviour and interspecific interactions between pilot whales and killer whales. She gained a BSc in Marine Vertebrate Zoology from Bangor University (UK) in 2015 and completed her Masters of Biology at the University of Iceland in 2019 investigating the call repertoire of Icelandic killer whales and comparing it to the repertoire of Norwegian killer whales.
