    • Environmental niche overlap in sibling planktonic species Calanus finmarchicus and C. glacialis in Arctic fjords 

      Weydmann-Zwolicka, Agata; Cottier, Finlo Robert; Berge, Jørgen; Majaneva, Sanna; Kuklinski, Piotr; Zwolicki, Adrian (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-08)
      Knowledge of environmental preferences of the key planktonic species, such as Calanus copepods in the Arctic, is crucial to understand ecosystem function and its future under climate change. Here, we assessed the environmental conditions influencing the development stages of Atlantic Calanus finmarchicus and Arctic Calanus glacialis, and we quantified the extent to which their niches overlap by ...

    • Recruitment of benthic invertebrates in high Arctic fjords: Relation to temperature, depth, and season 

      Meyer, Kirstin S.; Sweetman, Andrew K; Kuklinski, Piotr; Leopold, Peter; Vogedes, Daniel Ludwig; Berge, Jørgen; Griffith, Colin; Young, Craig M; Renaud, Paul (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-30)
      In the high Arctic, recruitment of hard-bottom benthic organisms has been studied at single locations, but little is known about how it varies spatially or temporally, or how it is influenced by abiotic factors. In this study, settlement plates were simultaneously deployed at five locations in three Svalbard (Norway) fjords at depths ranging from 7 m to 215 m. Recruitment was significantly different ...

    • Seasonality of occurrence and recruitment of Arctic marine benthic invertebrate larvae in relation to environmental variables 

      Kuklinski, Piotr; Berge, Jørgen; McFadden, Laurel; Dmoch, Katarzyna; Zajaczkowski, Marek; Nygård, Henrik Andreas; Piwosz, Kasia; Tatarek, Agnieszka (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      The Arctic system is one of the regions most influenced by ongoing global climate change, but there are still critical gaps in our knowledge regarding a substantial number of biological processes. This is especially true for processes taking place during the Arctic winter but also for seasonal processes, such as the dynamics of intra-annual meroplankton occurrence. Here, we report on a ...

    • Summer and winter MgCO3 levels in the skeletons of Arctic bryozoans 

      Iglikowska, Anna; Krzemińska, Małgorzata; Renaud, Paul Eric; Berge, Jørgen; Hop, Haakon; Kuklinski, Piotr (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-02)
      <p>In the Arctic, seasonal patterns in seawater biochemical conditions are shaped by physical, chemical, and biological processes related to the alternation of seasons, i.e. winter polar night and summer midnight sun. In summertime, CO<sub>2</sub> concentration is driven by photosynthetic activity of autotrophs which raises seawater pH and carbonate saturation state (Ω). In addition, restriction of ...
