      Numerical models o ecological systems are increasingly used to address complex environmental and resource management questions. One challenge or scientists, managers, and stakeholders is to appraise how well suited these ...
    • Abundance and biomass of copepods and cladocerans in Atlantic and Arctic domains of the Barents Sea ecosystem 

      Skjoldal, Hein Rune; Aarflot, Johanna Myrseth (Peer reviewed; Journal article, 2023)
      Zooplankton in the Barents Sea have been monitored annually with a standard procedure with determination of size-fractioned biomass since the mid-1980s. Biomass of copepods and cladocerans was estimated based on measured ...
    • Caught in broad daylight: Topographic constraints of zooplankton depth distributions 

      Aarflot, Johanna Myrseth; Aksnes, Dag Lorents; Opdal, Anders Frugård; Skjoldal, Hein Rune; Fiksen, Øyvind (Journal article; Peer reviewed, 2018)
      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, 2017)
    • Foraging success in planktivorous fish increases with topographic blockage of prey distributions 

      Aarflot, Johanna Myrseth; Dalpadado, Padmini; Fiksen, Øyvind (Peer reviewed; Journal article, 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 ...
    • New insights into the Barents Sea Calanus glacialis population dynamics and distribution 

      Aarflot, Johanna Myrseth; Eriksen, Elena; Prokopchuk, Irina P.; Svensen, Camilla; Søreide, Janne; Wold, Anette; Skogen, Morten D. (Peer reviewed; Journal article, 2023)
      Arctic copepods are major grazers and vital food for planktivores in polar ecosystems but challenging to observe due to remoteness and seasonal sea ice coverage. Models offer higher spatio-temporal resolution, and ...
    • Samlet påvirkning i foreslåtte særlig verdifulle og sårbare områder i norske havområder 

      Hansen, Cecilie; Aarflot, Johanna Myrseth; Eriksen, Elena; Husson, Berengere; Fauchald, Per; Johansen, Geir Odd; Jørgensen, Lis Lindal; van der Meeren, Gro Ingleid; Mikkelsen, Nina; Ottersen, Geir; von Quillfeldt, Cecilie; Skern-Mauritzen, Mette (Rapport fra havforskningen;2022 - 46, Research report, 2022)
      I dette arbeidet er det gjort en vurdering av risiko fra samlet påvirkning med tilhørende usikkerhet for aktive sektorer i norske havområder, for hvert av havområdene Nordsjøen, Norskehavet og Barentshavet, og for hvert ...
    • Seasonal and interannual variability in abundance and population development of Calanus finmarchicus at the western entrance to the Barents Sea, 1995–2019 

      Skjoldal, Hein Rune; Aarflot, Johanna Myrseth; Bagøien, Espen; Skagseth, Øystein; Rønning, Jon S.; Lien, Vidar Suren (Peer reviewed; Journal article, 2021)
      Data on copepodid abundance and stage composition of Calanus finmarchicus was collected with seasonal resolution (5–6 times a year) from four stations along an oceanographic transect across the western Barents Sea Opening ...

    • Transportation and predation control structures the distribution of a key calanoid in the Nordic Seas 

      Aarflot, Johanna Myrseth; Hjøllo, Solfrid Sætre; Strand, Espen; Skogen, Morten D. (Peer reviewed; Journal article, 2022)
      The largest Calanus species in the Nordic Seas is also the copepod for which we have the poorest knowledge. Recent studies have shown that C. hyperboreus is more likely of sub-Arctic rather than Arctic origins, and the ...
    • 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 (Peer reviewed; Journal article, 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 ...
