  • Bakterievekst under naturtørking av tørrfisk: Sammenligning av normal- og mucosovev 

    Bjørkevoll, Ingebrigt; Landfald, Bjarne; Ernstsen, Marita Holm; Joensen, Sjurdur; Tidemann, Even (Research report; Forskningsrapport, 2008-04)
    Mikroorganismer antas å påvirke utviklingen av lukt og smak i tørrfisk, men det er lite er kjent om hvilke organismer som dominerer under tørkeprosessen. Samtidig er mikrobielle forhold er også antatt å være essensielle for utviklingen av mucoso, som er en kvalitetsfeil i tørrfisk der deler av fiskemuskelen blir oppløst og slimaktig. Slike partier må skjæres bort under bløtingsprosessen. Denne ...

    The tundra is warming more rapidly than any other biome on Earth, and the potential ramifications are far-reaching because of global feedback effects between vegetation and climate. A better understanding of how environmental factors shape plant structure and function is crucial for predicting the consequences of environmental change for ecosystem functioning. Here we explore the biome-wide relationships ...
  • Understanding researchers’ intention and habit regarding publishing in open access journals 

    Moksness, Lars (Doctoral thesis; Doktorgradsavhandling, 2018-12-13)
    Scholarly publishing is the vessel for the dissemination of research articles. Contemporary scholarly publishing is achieved by two main models, open access (OA) and non-open access (non-OA). OA refers to articles that are available at no cost to the end-user; however, authors may incur a fee for accepted manuscripts. Non-OA articles are available at a cost, either via subscriptions or via individual ...

    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 spatial patterns in food-web structure are associated with environmental gradients in the Barents Sea, a highly productive shelf sea of the Arctic Ocean. We compared food webs ...
  • Northern cod species face spawning habitat losses if global warming exceeds 1.5°C 

    Dahlke, Flemming T.; Butzin, Martin; Nahrgang, Jasmine; Puvanendran, Velmurugu; Mortensen, Atle; Pörtner, Hans-Otto; Storch, Daniela (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-28)
    Rapid climate change in the Northeast Atlantic and Arctic poses a threat to some of the world’s largest fish populations. Impacts of warming and acidification may become accessible through mechanism-based risk assessments and projections of future habitat suitability. We show that ocean acidification causes a narrowing of embryonic thermal ranges, which identifies the suitability of spawning ...

  • Ballasting by cryogenic gypsum enhances carbon export in a Phaeocystis under-ice bloom 

    Wollenburg, JE; Katlein, C; Nehrke, Gernot; Nöthig, E.-M; Matthiessen, J; Wolf-Gladrow, Dieter A.; Nikolopoulos, A.; Gazquez-Sanchez, F; Rossmann, L; Assmy, Philipp; Babin, Marcel; Bruyant, F; Beaulieu, Michaël; Dybwad, Christine; Peeken, Ilka (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-16)
    Mineral ballasting enhances carbon export from the surface to the deep ocean; however, little is known about the role of this process in the ice-covered Arctic Ocean. Here, we propose gypsum ballasting as a new mechanism that likely facilitated enhanced vertical carbon export from an under-ice phytoplankton bloom dominated by the haptophyte Phaeocystis. In the spring 2015 abundant gypsum crystals ...
