      <ol> <li>Climate change is commonly associated with many species redistributions and the influence of other factors may be marginalized, especially in the rapidly warming Arctic.</li> <li>The Barents Sea, a high latitude large marine ecosystem in the Northeast Atlantic has experienced above‐average temperatures since the mid‐2000s with divergent bottom temperature trends at subregional ...
    • The rise of a marine generalist predator and the fall of beta diversity 

      Ellingsen, Kari; Yoccoz, Nigel; Tveraa, Torkild; Frank, Kenneth T.; Johannesen, Edda; Anderson, Marti J.; Dolgov, Andrey V.; Shackell, Nancy L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-17)
      Determining the importance of physical and biological drivers in shaping biodiversity in diverse ecosystems remains a global challenge. Advancements have been made towards this end in large marine ecosystems with several studies suggesting environmental forcing as the primary driver. However, both empirical and theoretical studies point to additional drivers of changes in diversity involving trophic ...
    • The role of a dominant predator in shaping biodiversity over space and time in a marine ecosystem 

      Ellingsen, Kari Elsa; Anderson, Marti J.; Shackell, Nancy L.; Tveraa, Torkild; Yoccoz, Nigel Gilles; Frank, Kenneth T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-24)
      Exploitation of living marine resources has resulted in major changes to populations of targeted species and functional groups of large-bodied species in the ocean. However, the effects of overfishing and collapse of large top predators on the broad-scale biodiversity of oceanic ecosystems remain largely unexplored. Populations of the Atlantic cod (Gadus morhua) were overfished and several collapsed ...
