    • Mixed interactions among life history stages of two harvested related species 

      Bellier, Edwige (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-07)
      Climate change and harvesting can affect the ecosystems' functioning by altering the population dynamics and interactions among species. Knowing how species interact is essential for better understanding potentially unintended consequences of harvest on multiple species in ecosystems. I analyzed how stage-specific interactions between two harvested competitors, the haddock (Melanogrammus aeglefinus) ...

    • Seasonal diversity dynamics of a boreal zooplankton community under climate impact 

      Bellier, Edwige; Engen, Steinar; Jensen, Thomas Correll (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-26)
      Seasonality and long-term environmental variability afect species diversity through their efects on the dynamics of species. To investigate such efects, we ftted a dynamic and heterogeneous species abundance model generating the lognormal species abundance distribution to an assemblage of freshwater zooplankton sampled fve times a year (June–October) during the ice-free period over 28 years ...

    • Sustainable strategies for harvesting predators and prey in a fluctuating environment 

      Bellier, Edwige; Sæther, Bernt-Erik; Engen, Steinar (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-12)
      The effects of harvest and fluctuating environment on inter-dependent predators and prey are complex and not well-known. We define a stochastic model where the predators and prey dynamically interact. The novelty of the model holds on the fact that predators and prey dynamics are simultaneously affected by correlated environmental noises. Interacting predators and prey are harvested using a proportional ...
