      Fossum, Petter; Mork, Kjell Arne; Tverberg, Vigdis; Boitsov, Stepan; Heldal, Hilde Elise; Bagøien, Espen; Rønning, Jon; Slotte, Aril; Vollen, Tone; Wienerroither, Rupert; Dahle, Geir; Buhl-Mortensen, Pål; Øien, Nils; Øigård, Tor Arne; Fauchald, Per (Rapport fra Havforskningen;Nr. 16 - 2012, Working paper, 2012-05)
      Resultatene fra et tokt med ”G.O. Sars” på Jan Mayenryggen i oktober 2011 blir sammenstilt med våre andre overvåkingsdata og info fra litteraturen. Hensikten med prosjektet er å beskrive miljø og marine ressurser på sokkelen ...
    • Density-dependent migratory waves in the marine pelagic ecosystem 

      Fauchald, Per; Mauritzen, Mette; Gjøsæter, Harald (Journal article; Peer reviewed, 2006-11)
      The migration of large aggregations of animals that sweep through the landscape is a phenomenon with large consequences in many ecosystems. It has been suggested that such migrations are mediated by resource depletion. ...
    • Diel vertical movements determine spatial interactions between cod, pelagic fish and krill on an Arctic shelf bank 

      Skaret, Georg; Johansen, Geir Odd; Johnsen, Espen; Fall, Johanna Jennifer Elisabeth; Fiksen, Øyvind; Englund, Gøran; Fauchald, Per; Gjøsæter, Harald; Macaulay, Gavin; Johannesen, Edda (Peer reviewed; Journal article, 2020)
      Predator-prey spatial interactions are essential to understand ecosystem processes like predation rates and trophic interaction strength. In marine systems, such spatial interactions are highly dynamic and difficult to ...
    • Feeding in a heterogeneous environment: spatial dynamics in summer foraging Barents Sea cod 

      Johannesen, Edda; Lindstrøm, Ulf; Michalsen, Kathrine; Skern-Mauritzen, Mette; Fauchald, Per; Bogstad, Bjarte; Dolgov, Andrey V. (Journal article; Peer reviewed, 2012-07-03)
      Cod Gadus morhua are important predators in many ecosystems in the North Atlantic, but their ecological importance has diminished in many areas due to stock size reductions. In contrast, the Barents Sea cod stock is ...
    • Poleward shifts in marine fisheries under Arctic warming 

      Fauchald, Per; Arneberg, Per; Debernard, Jens Boldingh; Lind, Sigrid; Olsen, Erik; Hausner, Vera Helene (Peer reviewed; Journal article, 2021)
      As global warming makes the Arctic Ocean more accessible, concerns have been raised about the environmental consequences of a possible expansion of commercial fisheries into pristine marine ecosystems. Using a recently ...
    • Sjøfugl og marine økosystemer. Status for sjøfugl og sjøfuglenes næringsgrunnlag i Norge og på Svalbard 

      Fauchald, Per; Barrett, Robert; Bustnes, Jan Ove; Erikstad, Kjell E; Nøttestad, Leif; Skern-Mauritzen, Mette; Vikebø, Frode Bendiksen (NINA rapport;1161, Research report, 2015)
      Denne synteserapporten beskriver hvordan endringene og fluktuasjonene i økosystemene i norske havområder påvirker næringsforholdene for sjøfugl. Disse endringene har konsekven-ser for sjøfuglsamfunnene langs kysten, og ...
    • Wasp-Waist Interactions in the North Sea Ecosystem 

      Fauchald, Per; Skov, Henrik; Skern-Mauritzen, Mette; Johns, David; Tveraa, Torkild (Journal article; Peer reviewed, 2011-07-28)
      Background In a “wasp-waist” ecosystem, an intermediate trophic level is expected to control the abundance of predators through a bottom-up interaction and the abundance of prey through a top-down interaction. Previous ...
