    • 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 ...

    • Shallow-Water Scavengers of Polar Night and Day – An Arctic Time-Lapse Photography Study 

      Bałazy, Piotr; Anderson, Marti J.; Chełchowski, Maciej; Włodarska-Kowalczuk, Maria; Kukliński, Piotr; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-24)
      Until recently, polar night constituted truly a “mare incognitum” of our times. Yet, the first records from this very little-explored period showcased a surprisingly rich and active ecosystem. This investigation aims to reveal the level of scavenger activity during both Arctic polar night and day. It compares the shallow-water scavenging fauna observed during two contrasting seasons (winter vs. ...
