    • Deep-sea sponge derived environmental DNA analysis reveals demersal fish biodiversity of a remote Arctic ecosystem 

      Brodnicke, Ole Bjørn; Meyer, Heidi Kristina; Busch, Kathrin; Xavier, Joana R.; Knudsen, Steen Wilhelm; Møller, Peter Daniel Rask; Hentschel, Ute Humeida; Sweet, Michael John (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-18)
      The deep-sea is vast, remote, and largely underexplored. However, methodological advances in environmental DNA (eDNA) surveys could aid in the exploration efforts, such as using sponges as natural eDNA filters for studying fish biodiversity. In this study, we analyzed the eDNA from 116 sponge tissue samples and compared these to 18 water eDNA samples and visual surveys obtained on an Arctic seamount. ...

    • Retention of ice-associated amphipods: possible consequences for an ice-free Arctic Ocean 

      Berge, Jørgen; Varpe, Øystein; Moline, Mark A.; Wold, A; Renaud, Paul; Daase, Malin; Falk-Petersen, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-09-12)
      Recent studies predict that the Arctic Ocean will have ice-free summers within the next 30 years. This poses a significant challenge for the marine organisms associated with the Arctic sea ice, such as marine mammals and, not least, the iceassociated crustaceans generally considered to spend their entire life on the underside of the Arctic sea ice. Based upon unique samples collected within ...
    • Is fisheries governance possible? 

      Johnsen, Jahn Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-02-11)
      Are there limits to the governability of a fishery? The establishment of a 200 nautical mile economic zone in Norway in 1977 made it possible to change from an open-access regime to a more closed one. In this process, the former self-regulating Norwegian fishing industry, to a large extent, accepted and adapted an explicit, hierarchical form of state-run governance. However, the process of change ...

      Klaudiussen, Isabell Kristin Pettersen (Master thesis; Mastergradsoppgave, 2023-05-31)
      Fotball er en sport med mange fans, men har over de siste tiårene blitt mer og mer preget av høye overgangssummer. Konkurranse for de beste premiene er spisset enda mer. Dermed er overganger blitt en svært viktig del av fotballhverdagen. Når en overgang blir betalt, vil jo denne fotballspilleren ha en slags estimert markedsverdi tilknyttet seg. Dermed er problemstillingen for denne forskningen ...
    • «Fordi når vi er ansatt her - 300 ansatte som 1 ansatt» - En kvalitativ studie om mangfoldsledelse i en mangfoldig norsk virksomhet 

      Khoshkhabari, Elisha (Master thesis; Mastergradsoppgave, 2023-05-28)
      Til tross for at ledelse av mangfoldige organisasjoner blir et stadig mer relevant tema i norske virksomheter, er det lite enstemmighet i hva slik ledelse innebærer - spesielt i praksis. En kritisk utfordring tatt i betraktning den generelle utviklingen i samfunnet mot stadig økt mangfold. Mangfoldsledelseslitteraturen i seg selv preges av lite progresjon, noe som øker behovet for ny kunnskap om hva ...

      Flores, Hauke; Veyssière, Gaëlle; Castellani, Giulia; Wilkinson, Jeremy; Hoppmann, Mario; Karcher, Michael; Valcic, Lovro; Cornils, Astrid; Geoffroy, Maxime; Nicolaus, Marcel; Niehoff, Barbara; Priou, Pierre; Schmidt, Katrin; Stroeve, Julienne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-28)
      As Arctic sea ice deteriorates, more light enters the ocean, causing largely unknown effects on the ecosystem. Using an autonomous biophysical observatory, we recorded zooplankton vertical distribution under Arctic sea ice from dusk to dawn of the polar night. Here we show that zooplankton ascend into the under-ice habitat during autumn twilight, following an isolume of 2.4 × 10<sup>−4</sup>  ...
    • Ghost fishing efficiency by lost, abandoned or discarded pots in snow crab (Chionoecetes opilio) fishery 

      Cerbule, Kristine; Herrmann, Bent; Grimaldo, Eduardo; Brinkhof, Jesse; Sistiaga, Manu; Larsen, Roger B.; Bak-Jensen, Zita (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-07)
      Marine pollution by lost, abandoned or otherwise discarded fishing gear (ALDFG) often has negative impact on the ecosystem through plastic pollution and continuous capture of marine animals, so-called “ghost fishing”. ALDFG in pot fisheries is associated with high ghost fishing risk. The snow crab (Chionoecetes opilio) pot fishery is conducted in harsh weather conditions increasing the risk of ...

    • The roles of brain lipids and polar metabolites in the hypoxia tolerance of deep-diving pinnipeds 

      Martens, Gerrit A.; Geßner, Cornelia; Folkow, Lars; Creydt, Marina; Fischer, Markus; Burmester, Thorsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-14)
      Lipids make up more than half of the human brain's dry weight, yet the composition and function of the brain lipidome is not well characterized. Lipids not only provide the structural basis of cell membranes, but also take part in a wide variety of biochemical processes. In neurodegenerative diseases, lipids can facilitate neuroprotection and serve as diagnostic biomarkers. The study of organisms ...
    • Økonomiske konsekvenser av økt skattekostnad for en havbruksaktør 

      Hansen, Rakel Ingeborg; Aamodt Grønlie, Sara (Master thesis; Mastergradsoppgave, 2023-05-29)
      Havbruksnæringen er en av de mest lønnsomme næringene i Norge. De naturgitte fortrinnene i kombinasjon med reguleringer fra myndighetene gir opphav til en ekstraordinær avkastning. På bakgrunn av dette foreslår regjeringen å innføre grunnrenteskatt på havbruk. Innføring av grunnrenteskatt og endringer i verdsettelsesregler av havbrukstillatelser gjør at havbruksaktører og deres eiere stilles overfor ...
    • Herbivory and warming have opposing short-term effects on plant-community nutrient levels across high-Arctic tundra habitats 

      Petit Bon, Matteo; Bråthen, Kari Anne; Ravolainen, Virve; Ottaviani, Gianluigi; Böhner, Hanna; Jonsdottir, Ingibjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-11)
      Environmental changes can rapidly alter standing biomass in tundra plant communities; yet, to what extent can they modify plant-community nutrient levels? Nutrient levels and their changes can affect biomass production, nutrient cycling rates and nutrient availability to herbivores. We examined how environmental perturbations alter Arctic plant-community leaf nutrient concentrations (percentage of ...
    • Ecological Drivers of Mercury Bioaccumulation in Fish of a Subarctic Watercourse 

      Amundsen, Per-Arne; Henriksson, Nina Matilda; Poste, Amanda; Prati, Sebastian; Power, Michael (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-02)
      Mercury (Hg) is a serious concern for aquatic ecosystems because it may biomagnify to harmful concentrations within food webs and consequently end up in humans that eat fish. However, the trophic transfer of mercury through the aquatic food web may be impacted by several factors related to network complexity and the ecology of the species present. The present study addresses the interplay between ...
    • Illegal fishing: A challenge to fisheries management in Norway 

      Standal, Dag; Hersoug, Bjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-30)
      The management of the Norwegian Northeast Atlantic cod fishery has in many ways been a success story; quotas have been high (but now declining), profitability has been higher than most other industries and there is great interest among young recruits to enter the fishery. However, over the last decade illegal fishing of allocated quotas and black-market transactions throughout the value chain ...
