    • Effects of habitat enrichment and food availability on the foraging behaviour of juvenile Atlantic Cod (Gadus morhua L) 

      Moberg, Olav; Braithwaite, Victoria A.; Jensen, Knut Helge; Salvanes, Anne Gro Vea (2011-04-13)
      The environment can play an important role in shaping how an animal behaves, and how well the animal performs in a particular environment can be influenced by early experiences. The tradition of releasing captive-reared ...

    • Empirical Support for Optimal Virulence in a Castrating Parasite 

      Jensen, Knut Helge; Little, Tom; Skorping, Arne; Ebert, Dieter (Public Library of Science, 2006-05-30)
      The trade-off hypothesis for the evolution of virulence predicts that parasite transmission stage production and host exploitation are balanced such that lifetime transmission success (LTS) is maximised. However, the ...

    • An enriched environment promotes shelter-seeking behaviour and survival of hatchery-produced juvenile European lobster (Homarus gammarus) 

      Aspaas, Stian; Grefsrud, Ellen Sofie; Fernø, Anders; Jensen, Knut Helge; Trengereid, Henrik; Agnalt, Ann-Lisbeth (PLOS, 2016-08-25)
      The high loss of newly released hatchery-reared European lobster (Homarus gammarus) juveniles for stock enhancement is believed to be the result of maladaptive anti-predator behaviour connected to deprived stimuli in the ...

    • Enrichment promotes learning in fish 

      Strand, David A.; Utne-Palm, Anne Christine; Jakobsen, Per Johan; Braithwaite, Victoria A.; Jensen, Knut Helge; Salvanes, Anne Gro Vea (Inter-Research, 2010-08-18)
      Captive birds and mammals reared in enriched rearing environments have been shown to behave more flexibly compared to animals reared in impoverished or plain environments. Recent evidence has shown that this is also true ...

    • Size Dependent Male Reproductive Tactic in the Two-Spotted Goby (Gobiusculus flavescens) 

      Utne-Palm, Anne Christine; Eduard, Kjartan; Jensen, Knut Helge; Mayer, Ian; Jakobsen, Per Johan (PLOS, 2015-12-07)
      Male investment in testes and sperm duct gland in the polygamous nest breeding two-spotted goby Gobiusculus flavescens (Fabricius) was investigated in relation to time in reproductive season and individual physical parameters. ...

    • State-dependent spatial and intra-school dynamics in pre-spawning herring (Clupea harengus L.) in a semi-enclosed ecosystem 

      Langård, Lise; Fatnes, Ole Andreas; Johannessen, Arne; Skaret, Georg; Axelsen, Bjørn Erik; Nøttestad, Leif; Slotte, Aril; Jensen, Knut Helge; Fernø, Anders (Inter-Research, 2013)
      Distribution and aggregation patterns of pelagic fish in marine ecosystems are hard to predict and understand, particularly since focused studies are typically limited to single field efforts. Our study targets coastal ...

    • When to reproduce? A new answer to an old question 

      Skorping, Arne; Jensen, Knut Helge; Mennerat, Adele; Högstedt, Göran (University of Chicago Press, 2016-04)
      We present a life-history model based on the assumptions that juvenile survival follows a negative exponential function and that fecundity gain increases linearly with time to maturity. This model predicts that the optimal ...
