    • Caught in broad daylight: Topographic constraints of zooplankton depth distributions 

      Aarflot, Johanna Myrseth; Aksnes, Dag Lorents; Opdal, Anders Frugård; Skjoldal, Hein Rune; Fiksen, Øyvind (Peer reviewed; Journal article, 2019-05)
      For visual predators, sufficient light is critical for prey detection and capture. Because light decays exponentially with depth in aquatic systems, vertical movement has become a widespread strategy among zooplankton for ...

    • Contribution of Calanus to the mesozooplankton biomass in the Barents Sea 

      Aarflot, Johanna Myrseth; Skjoldal, Hein Rune; Dalpadado, Padmini; Skern-Mauritzen, Mette (Peer reviewed; Journal article, 2018)
      Copepods from the genus Calanus are crucial prey for fish, seabirds and mammals in the Nordic and Barents Sea ecosystems. The objective of this study is to determine the contribution of Calanus species to the mesozooplankton ...

    • Ethical approaches for engaging extended peer communities: Insight into responsible workshopping with citizens 

      Fuller, Jessica Leyla; Bjørkan, Maiken; Iversen, Lisbeth; Aarflot, Johanna Myrseth; Dankel, Dorothy Jane (Journal article; Peer reviewed, 2025)
      The United Nation’s Sustainable Development Goals (SDGs) represent the most ambitious and encompassing global framework for ecological, economic, and social sustainability for our planet to date. However, the relevance of ...

    • Foraging success in planktivorous fish increases with topographic blockage of prey distributions 

      Aarflot, Johanna Myrseth; Dalpadado, Padmini; Fiksen, Øyvind (Journal article; Peer reviewed, 2020)
      Banks and shelves are productive zones of the ocean, and often home to large fish stocks. Can shallower bottom topographies improve foraging opportunities for pelagic fish by blocking zooplankton from hiding in deep, darker ...

    • 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; Peer reviewed, 2022)
      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 ...

    • Three-dimensional zooplankton distributions seen through the lens of fish in the Barents Sea 

      Aarflot, Johanna Myrseth (Doctoral thesis, 2019-04-08)
      My aim with this dissertation is to enhance our knowledge of food availability and foraging opportunities for planktivorous fish over the Barents Sea bathymetry. The Barents Sea is a highly productive sub-Arcic shelf sea ...

    • Visual predation risk and spatial distributions of large Arctic copepods along gradients of sea ice and bottom depth 

      Langbehn, Tom; Aarflot, Johanna Myrseth; Freer, Jennifer J.; Varpe, Øystein (Journal article; Peer reviewed, 2023)
      Changes in the community size structure of Arctic copepods toward smaller and less fat individuals or species have been linked to environmental changes. The underpinning mechanisms are, however, poorly understood. We use ...
