    • Climate change alters the structure of arctic marine food webs due to poleward shifts of boreal generalists 

      Kortsch, Susanne; Primicerio, Raul; Fossheim, Maria; Dolgov, Andrey V.; Aschan, Michaela (Journal article; Peer reviewed, 2015-09-07)
      Climate-driven poleward shifts, leading to changes in species composition and relative abundances, have been recently documented in the Arctic. Among the fastest moving species are boreal generalist fish which are expected ...

    • Climate-driven changes in functional biogeography of Arctic marine fish communities 

      Frainer, André; Primicerio, Raul; Kortsch, Susanne; Aune, Magnus; Dolgov, Andrey V.; Fossheim, Maria; Aschan, Michaela (Peer reviewed; Journal article, 2017)

    • Food-web structure varies along environmental gradients in a high-latitude marine ecosystem 

      Kortsch, Susanne; Primicerio, Raul; Aschan, Michaela; Lind, Sigrid; Dolgov, Andrey V.; Planque, Benjamin (Journal article; Peer reviewed, 2018)
      Large‐scale patterns in species diversity and community composition are associated with environmental gradients, but the implications of these patterns for food‐web structure are still unclear. Here, we investigated how ...

    • Novel feeding interactions amplify the impact of species redistribution on an Arctic food web 

      Pecuchet, Laurene; Blanchet, Marie-Anne; Frainer, Andre barbosa; Husson, Bérengère; Jørgensen, Lis Lindal; Kortsch, Susanne; Primicerio, Raul (Peer reviewed; Journal article, 2020)
      Species are redistributing globally in response to climate warming, impacting ecosystem functions and services. In the Barents Sea, poleward expansion of boreal species and a decreased abundance of Arctic species are causing ...

    • The role of marine mammals in the Barents Sea foodweb 

      Blanchet, Marie-Anne; Primicerio, Raul; Frainer, André; Kortsch, Susanne; Skern-Mauritzen, Mette; Dolgov, Andrey V.; Aschan, Michaela (Peer reviewed; Journal article, 2019)
      Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 ...
