    • Narrow lenses for capturing the complexity of fisheries: A topic analysis of fisheries science from 1990 to 2016 

      Syed, Shaheen; Borit, Melania; Spruit, Marco (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-20)
      Despite increased fisheries science output and publication outlets, the global crisis in fisheries management is as present as ever. Since a narrow research focus may be a contributing factor to this failure, this study uncovers topics in fisheries research and their trends over time. This interdisciplinary research evaluates whether science is diversifying fisheries research topics in an attempt ...
    • The Nasal Geometry of the Reindeer Gives Energy-Efficient Respiration 

      Magnanelli, Elisa; Wilhelmsen, Øivind; Acquarone, Mario; Folkow, Lars; Kjelstrup, Signe (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-14)
      Reindeer in the arctic region live under very harsh conditions and may face temperatures below 233 K. Therefore, efficient conservation of body heat and water is important for their survival. Alongside their insulating fur, the reindeer nasal mechanism for heat and mass exchange during respiration plays a fundamental role. We present a dynamic model to describe the heat and mass transport that takes ...
    • The Neglected Marine Fungi, Sensu stricto, and Their Isolation for Natural Products’ Discovery 

      Overy, David P.; Rämä, Teppo; Oosterhuis, Rylee; Walker, Allison K.; Pang, Ka-Lai (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-10)
      Despite the rapid development of molecular techniques relevant for natural product research, culture isolates remain the primary source from which natural products chemists discover and obtain new molecules from microbial sources. Techniques for obtaining and identifying microbial isolates (such as filamentous fungi) are thus of crucial importance for a successful natural products’ discovery program. ...
    • Nemo-effekten og koraller 

      Armstrong, Claire W.; Aanesen, Margrethe (Journal article; Tidsskriftartikkel, 2014-05-07)
      Bryr den norske befolkningen seg om dyphavet og de organismer som lever der selv om vi ikke har noen direkte nytte av dem? Er vi villig til å ofre økonomisk aktivitet som fiskeri og oljevirksomhet for beskytte miljøet i dyphavet? Vår studie sier ja.

      Logashina, Yulia A.; Solstad, Runar Gjerp; Mineev, Konstantin S.; Korolkova, Yuliya V.; Mosharova, Irina V.; Dyachenko, Igor A.; Palikov, Victor A.; Palikova, Yulia A.; Murashev, Arkadii N.; Arseniev, Alexander S.; Kozlov, Sergey A.; Stensvåg, Klara; Haug, Tor; Andreev, Yaroslav A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-29)
      A novel bioactive peptide named τ-AnmTx Ueq 12-1 (short name Ueq 12-1) was isolated and characterized from the sea anemone Urticina eques. Ueq 12-1 is unique among the variety of known sea anemone peptides in terms of its primary and spatial structure. It consists of 45 amino acids including 10 cysteine residues with an unusual distribution and represents a new group of sea anemone peptides. The 3D ...
    • Non‐specific amplification compromises environmental DNA metabarcoding with COI 

      Collins, Rupert A.; Bakker, Judith; Wangensteen Fuentes, Owen Simon; Soto, Ana Z.; Corrigan, Laura; Sims, David W.; Genner, Martin J.; Mariani, Stefano (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-02)
      <ol> <li>Metabarcoding extra‐organismal DNA from environmental samples is now a key technique in aquatic biomonitoring and ecosystem health assessment. Of critical consideration when designing experiments, and especially so when developing community standards and legislative frameworks, is the choice of genetic marker and primer set. Mitochondrial cytochrome c oxidase subunit I (COI), the standard ...
    • Nordic experience of fisheries management. Seen in relation to the reform of the EU Common Fisheries Policy. 

      Holm, Petter; Eliasen, Søren; Sverdrup-Jensen, Sten; Johnsen, Jahn Petter (Research report; Forskningsrapport, 2009)
      The waters surrounding the Nordic countries are rich in fish resources. Up to this date fisheries has been among the most important productive sectors in the Nordic economies, and in the Faroe Islands and Greenland it is by far the most important sector. Management of marine fisheries has over time had various objectives in the Nordic countries, ranging from fiscal and social purposes to stock ...

    • The Norwegian coastal employment system: What It Was and What It Is 

      Sønvisen, Signe Annie; Johnsen, Jahn Petter; Vik, Jostein (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Norwegian fisheries have undergone tremendous changes, due to technological developments and the introduction of resource management. In addition, societal changes and in particular the introduction of formal requirements and the formalization of training and education, have also greatly affected the fishing fleet. Jentoft and Wadel (1984) described the Coastal Employment System. This system was ...
    • Novel antimicrobial peptides EeCentrocins 1, 2 and EeStrongylocin 2 from the Edible sea urchin Echinus esculentus have 6-br-trp post-translational modifications 

      Solstad, Runar Gjerp; Li, Chun; Isaksson, Johan; Johansen, Jostein a; Svenson, Johan; Stensvåg, Klara; Haug, Tor (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-23)
      The global problem of microbial resistance to antibiotics has resulted in an urgent need to develop new antimicrobial agents. Natural antimicrobial peptides are considered promising candidates for drug development. Echinoderms, which rely on innate immunity factors in the defence against harmful microorganisms, are sources of novel antimicrobial peptides. This study aimed to isolate and characterise ...

    • Omega-3 Fatty Acids and Cardiovascular Diseases: Effects, Mechanisms and Dietary Relevance 

      Mæhre, Hanne K; Jensen, Ida-Johanne; Elvevoll, Edel Oddny; Eilertsen, Karl-Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-18)
      ω-3 fatty acids (n-3 FA) have, since the 1970s, been associated with beneficial health effects. They are, however, prone to lipid peroxidation due to their many double bonds. Lipid peroxidation is a process that may lead to increased oxidative stress, a condition associated with adverse health effects. Recently, conflicting evidence regarding the health benefits of intake of n-3 from seafood or ...
    • On the numerous concepts in invasion biology 

      Falk-Petersen, Jannike; Bøhn, Thomas; Sandlund, Odd Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-01-20)
      The study of biological invasions has triggered the production of a diversity of concepts. The terminology has, however, often been applied inconsistently and inaccurately. This article lists and assesses the most commonly used terms and concepts in invasion ecology. In each case the most coherent definition and use is suggested.
