• 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 ...
    • Functional roles and redundancy of demersal Barents Sea fish: Ecological implications of environmental change 

      Aune, Magnus; Aschan, Michaela; Greenacre, Michael; Dolgov, Andrey V.; Fossheim, Maria; Primicerio, Raul (Journal article; Peer reviewed, 2018)
      When facing environmental change and intensified anthropogenic impact on marine ecosystems, extensive knowledge of how these systems are functioning is required in order to manage them properly. However, in high-latitude ...
    • Increased functional diversity warns of ecological transition in the Arctic 

      Frainer, André; Primicerio, Raul; Dolgov, Andrey V.; Fossheim, Maria; Johannesen, Edda; Lind, Sigrid; Aschan, Michaela (Peer reviewed; Journal article, 2021)
      As temperatures rise, motile species start to redistribute to more suitable areas, potentially affecting the persistence of several resident species and altering biodiversity and ecosystem functions. In the Barents Sea, a ...
    • 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 ...
