      Oil-adjuvanted vaccines reduce long-term growth in farmed Atlantic salmon Salmo salar, possibly via an increase in metabolic rate due to the energetic demands of the immune system. We tested this hypothesis by comparing ...

      Fall, Johanna Jennifer Elisabeth; Fiksen, Øyvind (Journal article; Peer reviewed, 2019)
      Predatory fish structure communities through prey pursuit and consumption and, in many marine systems, the gadoids are particularly important. These predators have flexible feeding behaviours and often feed on large prey ...

    • Non-deterministic modelling of food-web dynamics 

      Planque, Benjamin; Lindstrøm, Ulf; Subbey, Samuel (Journal article; Peer reviewed, 2014-10-09)
      A novel approach to model food-web dynamics, based on a combination of chance (randomness) and necessity (system constraints), was presented by Mullon et al. in 2009. Based on simulations for the Benguela ecosystem, they ...
