    • Empirical Support for Optimal Virulence in a Castrating Parasite 

      Jensen, Knut Helge; Little, Tom; Skorping, Arne; Ebert, Dieter (Peer reviewed; Journal article, 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 ...

    • Intensive Farming: Evolutionary Implications for Parasites and Pathogens 

      Mennerat, Adèle; Nilsen, Frank; Ebert, Dieter; Skorping, Arne (Peer reviewed; Journal article, 2010)
      An increasing number of scientists have recently raised concerns about the threat posed by human intervention on the evolution of parasites and disease agents. New parasites (including pathogens) keep emerging and parasites ...

    • Invest more and die faster: The life history of a parasite on intensive farms 

      Mennerat, Adele; Ugelvik, Mathias Stølen; Jensen, Camilla Håkonsrud; Skorping, Arne (Peer reviewed; Journal article, 2017-10)
      Organisms are expected to respond to alterations in their survival by evolutionary changes in their life history traits. As agriculture and aquaculture have become increasingly intensive in the past decades, there has been ...

    • Ontogenetic Change in Behavioral Responses to Structural Enrichment From Fry to Parr in Juvenile Atlantic Salmon (Salmo salar L.) 

      Alnes, Ingeborg Bjerkvik; Jensen, Knut Helge; Skorping, Arne; Salvanes, Anne Gro Vea (Journal article; Peer reviewed, 2021)
      Enrichment is widely used as a tool for studying how changes in environment affect animal behavior. Here, we report an experimental study investigating if behaviors shaped by stimuli from environmental enrichment depending ...

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

      Skorping, Arne; Jensen, Knut Helge; Mennerat, Adele; Högstedt, Göran (Peer reviewed; Journal article, 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 ...
