    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-23)
      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 restricting those movements. Continuous darkness during the Arctic polar night has been suggested to impair foraging in visually searching boreal fish and may thus limit their northward ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-06)
      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 (<i>Leptoclinus maculatus</i>) from the Arctic, characterizing its development as it undergoes a series of changes in the organ and tissue organization, especially during the postlarvae transition from the ...

    • Variability and decadal trends in the Isfjorden (Svalbard) ocean climate and circulation – An indicator for climate change in the European Arctic 

      Skogseth, Ragnheid; Olivier, Léa L.A.; Nilsen, Frank; Falck, Eva; Fraser, Neil J.; Tverberg, Vigdis; Ledang, Anna Birgitta; Vader, Anna; Jonassen, Marius Opsanger; Søreide, Janne; Cottier, Finlo Robert; Berge, Jørgen; Ivanov, Boris V.; Falk-Petersen, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Isfjorden, a broad Arctic fjord in western Spitsbergen, has shown significant changes in hydrography and inflow of Atlantic Water (AW) the last decades that only recently have been observed in the Arctic Ocean north of Svalbard. Variability and trends in this fjord’s climate and circulation are therefore analysed from observational and reanalysis data during 1987 to 2017. Isfjorden experienced a ...

    • Zooplankton in Svalbard fjords on the Atlantic–Arctic boundary 

      Gluchowska, Marta; Kwasniewski, Slawomir; Prominska, Agnieszka; Olszewska, Anna; Goszczko, Ilona; Falk-Petersen, Stig; Hop, Haakon; Weslawski, Jan Marcin (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-01)
      Zooplankton abundance and community structures were studied in three west Spitsbergen fjords at the beginning of the warm phase, which seem to have entered in 2006. Sampling was conducted in summer 2007 at stations distributed along transects in Hornsund, Isfjorden and Kongsfjorden. Variations in zooplankton standing stocks and community structures (assessing taxonomic diversity and zoogeographical ...
