    • Investigating the drivers of the Nordic Seas food-web dynamics using Chance and Necessity modelling 

      Sivel, Elliot (Doctoral thesis; Doktorgradsavhandling, 2022-04-22)
      Marine ecosystems are under pressures of human activities that have altered their dynamics and structure during the last five decades, but there can also vary due to internal dynamics or chance. Managers focus on human activities and often ignore the contribution of internal dynamics and chance to ecosystem dynamics in the decision-making process. In this thesis, I use food-web modelling based on ...

    • Multiple configurations and fluctuating trophic control in the Barents Sea food-web 

      Sivel, Elliot; Planque, Benjamin; Lindstrøm, Ulf; Yoccoz, Nigel G. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-09)
      The Barents Sea is a subarctic shelf sea which has experienced major changes during the past decades. From ecological time-series, three different food-web configurations, reflecting successive shifts of dominance of pelagic fish, demersal fish, and zooplankton, as well as varying trophic control have been identified in the last decades. This covers a relatively short time-period as available ...
