    • Connections to the Deep: Deep Vertical Migrations, an Important Part of the Life Cycle of Apherusa glacialis, an Arctic Ice-Associated Amphipod 

      Drivdal, Magnus; Kunisch, Erin; Bluhm, Bodil; Gradinger, Rolf; Falk-Petersen, Stig; Berge, Jørgen (Peer reviewed; Journal article, 2021)
      Arctic sea ice contains a substantial amount of living biota of which part is lost through melt and export out of the Arctic Ocean every year. It is unclear how populations can be maintained within the Arctic Ocean. A ...
    • Diets of gadoid fish in Arctic waters of Svalbard fjords during the polar night 

      Larsen, Lars-Henrik; Cusa, Marine Lure Joana; Eglund-Newby, Sam; Berge, Jørgen; Renaud, Paul Eric; Varpe, Øystein; Geoffroy, Maxime; Falk-Petersen, Stig (Peer reviewed; Journal article, 2023)
      As the climate warms, boreal fish species are expected to expand into the Arctic domain. Though water temperature is an important factor driving expansion of aquatic species, other variables may play a critical role in ...
    • Fatty Acids Composition of the Muscles of Leptoclinus maculatus (Stichaeidae) postlarvae from Kongsfjord and Rijpfjord, Spitsbergen 

      Pekkoeva, S.N.; Voronin, V.P.; Falk-Petersen, Stig; Berge, Jørgen; Nemova, N.N.; Murzina, S.A (Peer reviewed; Journal article, 2022)
      The fatty acids composition of total lipids and individual lipid classes (phospholipids and triacylglycerols) were studied in the muscles of daubed shanny Leptoclinus maculatus postlarvae at different stages of development ...
    • In the dark: a review of ecosystem processes during the Arctic polar night 

      Berge, Jørgen; Renaud, Paul; Darnis, Gérald; Cottier, Finlo; Last, Kim; Gabrielsen, Tove M.; Johnsen, Geir; Seuthe, Lena; Weslawski, Jan Marcin; Leu, Eva; Moline, Mark A.; Nahrgang, Jasmine; Søreide, Janne; Varpe, Øystein; Lønne, Ole Jørgen; Daase, Malin; Falk-Petersen, Stig (Journal article, 2015)
      Several recent lines of evidence indicate that the polar night is key to understanding Arctic marine ecosystems. First, the polar night is not a period void of biological activity even though primary production is close ...
    • Is ambient light during the high Arctic polar night sufficient to act as a visual cue for zooplankton? 

      Cohen, Jonathan H.; Berge, Jørgen; Moline, Mark A.; Sørensen, Asgeir Johan; Last, Kim; Falk-Petersen, Stig; Renaud, Paul; Leu, Eva; Grenvald, Julie Cornelius; Cottier, Finlo; Cronin, Heather; Menze, Sebastian; Norgren, Petter; Varpe, Øystein; Daase, Malin; Darnis, Gérald; Johnsen, Geir (Journal article, 2015)
      The light regime is an ecologically important factor in pelagic habitats, influencing a range of biological processes. However, the availability and importance of light to these processes in high Arctic zooplankton communities ...
    • Ontogenetic changes in the body structure of the Arctic fish Leptoclinus maculatus 

      Pekkoeva, S.N.; Kondakova, E.A.; Falk-Petersen, Stig; Berge, Jørgen; Murzina, S.A (Peer reviewed; Journal article, 2023)
      Histological studies of the ontogenetic changes in Arctic marine fishes are often fragmented and incomplete. Here we present a comprehensive histological ontogenetic analysis of the daubed shanny (Leptoclinus maculatus) ...
