    • Combined effects of temperature and fishing mortality on the Barents Sea ecosystem stability 

      Sivel, Elliot Manuarii; Planque, Benjamin; Lindstrøm, Ulf Ove; Yoccoz, Nigel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-16)
      Temporal variability in abundance and composition of species in marine ecosystems results from a combination of internal processes, external drivers, and stochasticity. One way to explore the temporal variability in an ecosystem is through temporal stability, measured using the inverse of the coefficient of variation for biomass of single species. The effect of temperature and fisheries on the ...

    • Food-web structure varies along environmental gradients in a high-latitude marine ecosystem 

      Kortsch, Susanne; Primicerio, Raul; Aschan, Michaela; Lind, Sigrid; Dolgov, Andrey V.; Planque, Benjamin (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-17)
      Large-scale patterns in species diversity and community composition are associated with environmental gradients, but the implications of these patterns for food-web structure are still unclear. Here, we investigated how spatial patterns in food-web structure are associated with environmental gradients in the Barents Sea, a highly productive shelf sea of the Arctic Ocean. We compared food webs ...

    • Functional diversity of the Barents Sea fish community 

      Wiedmann, Magnus Aune; Aschan, Michaela; Certain, Gregoire; Dolgov, Andrey V.; Greenacre, Michael; Johannesen, Edda; Planque, Benjamin; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      This paper provides the first assessment of the functional diversity (FD) of the Barents Sea fish community. FD is recognized as an important driver of ecosystem functions and, thus, governs the adaptability of ecosystems in the face of disturbance. We integrate ecosystem survey data with an extensive trait matrix and show that fish FD displayed large spatial variation. The study period (2004 to ...

    • 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 ...

    • A participatory scenario method to explore the future of marine social‐ecological systems 

      Planque, Benjamin; Mullon, Christian; Arneberg, Per; Eide, Arne; Fromentin, Jean-Marc; Heymans, Johanna J; Hoel, Alf Håkon; Niiranen, Susa; Ottersen, Geir; Sandø, Anne Britt; Sommerkorn, Martin; Thébaud, Olivier; Thorvik, Thorbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-01)
      Anticipating future changes in marine social‐ecological systems (MSES) several decades into the future is essential in the context of accelerating global change. This is challenging in situations where actors do not share common understandings, practices, or visions about the future. We introduce a dedicated scenario method for the development of MSES scenarios in a participatory context. The objective ...

    • A standard protocol for describing the evaluation of ecological models 

      Planque, Benjamin; Aarflot, Johanna Myrseth; Buttay, Lucie; Carroll, JoLynn; Fransner, Sara Filippa Krusmynta; Hansen, Cecilie; Husson, Berengere; Langangen, Øystein Ole Gahr; Lindstrøm, Ulf Ove; Pedersen, Torstein; Primicerio, Raul; Sivel, Elliot Manuarii; Skogen, Morten D.; Strombom, Evelyn; Stige, Leif Christian; Varpe, Øystein; Yoccoz, Nigel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-21)
      Numerical models of ecological systems are increasingly used to address complex environmental and resource management questions. One challenge for scientists, managers, and stakeholders is to appraise how well suited these models are to answer questions of scientific or societal relevance, that is, to perform, communicate, or access transparent evaluations of ecological models. While there have been ...
