    • Distribution of rorquals and Atlantic cod in relation to their prey in the Norwegian high Arctic 

      Solvang, Hiroko K.; Haug, Tore; Knutsen, Tor; Gjøsæter, Harald; Bogstad, Bjarte; Hartvedt, Siri; Øien, Nils; Lindstrøm, Ulf (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-14)
      Recent warming in the Barents Sea has led to changes in the spatial distribution of both zooplankton and fish, with boreal communities expanding northwards. A similar northward expansion has been observed in several rorqual species that migrate into northern waters to take advantage of high summer productivity, hence feeding opportunities. Based on ecosystem surveys conducted during August–September ...

    • Foraging movements of humpback whales relate to the lateral and vertical distribution of capelin in the Barents Sea 

      Vogel, Emma; Skalmerud, Emma; Biuw, Martin; Blanchet, Marie-Anne; Kleivane, Lars; Skaret, Georg; Øien, Nils; Rikardsen, Audun (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-24)
      Understanding how individual animals modulate their behaviour and movement patterns in response to environmental variability plays a central role in behavioural ecology. Marine mammal tracking studies typically use physical environmental characteristics that vary, and/or proxies of prey distribution, to explain predator movements. Studies linking predator movements and the actual distributions ...

    • Strong and lasting impacts of past global warming on baleen whales and their prey 

      Cabrera, Andrea A.; Schall, Elena; Berube, Martine; Anderwald, Pia; Berrow, Simon; Best, Peter B.; Cunha, Haydée A.; Dalla Rosa, Luciano; Dias, Carolina P.; Findlay, Kenneth P.; Haug, Tore; Heide-Jørgensen, Mads-Peter; Hoelzel, A.

(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-02)
      Global warming is affecting the population dynamics and trophic interactions across a wide range of ecosystems and habitats. Translating these real-time effects into their long-term consequences remains a challenge. The rapid and extreme warming period that occurred after the Last Glacial Maximum (LGM) during the Pleistocene–Holocene transition (7–12 thousand years ago) provides an opportunity ...
