    • Copepods’ true colors: astaxanthin pigmentation as an indicator of fitness 

      Vilgrain, Laure; Maps, Frédéric; Basedow, Sünnje Linnéa; Trudnowska, Emilia; Madoui, Mohammed-Amin; Niehoff, Barbara; Ayata, Sakina‐Dorothée (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-08)
      Pigmentation is often overlooked in zooplankton, since these organisms are mostly colorless to fit the translucid water medium. However, one of the dominant zooplankton taxa in aquatic ecosystems—copepods—often show a bright red-orange or blue coloration owing to the accumulation of carotenoid pigments in some parts of their bodies. Even though there are many functional traits describing copepod’s ...

    • Molecular tools prove little auks from Svalbard are extremely selective for Calanus glacialis even when exposed to Atlantification 

      Balazy, Kaja; Trudnowska, Emilia; Wojczulanis-Jakubas, Katarzyna; Jakubas, Dariusz; Præbel, Kim; Choquet, Marvin; Brandner, Melissa Michelle; Schultz, Mads; Bitz-Thorsen, Julie; Boehnke, Rafał; Szeligowska, Marlena; Descamps, Sebastien; Strøm, Hallvard; Blachowiak-Samolyk, Kasia (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-22)
      Two Calanus species, C. glacialis and C. finmarchicus, due to different life strategies and environmental preferences act as an ecological indicators of Arctic Atlantification. Their high lipid content makes them important food source for higher trophic levels of Arctic ecosystems including the most abundant Northern Hemisphere's seabird, the little auk (Alle alle). Recent studies indicate a critical ...

    • Remote sensing of zooplankton swarms 

      Basedow, Sünnje Linnéa; McKee, David; Lefering, Ina; Gislason, Astthor; Daase, Malin; Trudnowska, Emilia; Egeland, Einar Skarstad; Choquet, Marvin; Falk-Petersen, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-24)
      Zooplankton provide the key link between primary production and higher levels of the marine food web and they play an important role in mediating carbon sequestration in the ocean. All commercially harvested fish species depend on zooplankton populations. However, spatio-temporal distributions of zooplankton are notoriously difficult to quantify from ships. We know that zooplankton can form large ...

    • Seasonal mesozooplankton patterns and timing of life history events in high-arctic fjord environments 

      Søreide, Janne; Dmoch, Katarzyna; Blachowiak-Samolyk, Katarzyna; Trudnowska, Emilia; Daase, Malin (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-11)
      Seasonal patterns in mesozooplankton composition, vertical distribution, and timing of reproduction are challenging to study in the open sea due to ocean currents and mix of populations of different origins. Sill fjords, on the other hand, with restricted water exchange, are ideal locations for studying taxa- and community-specific adaptations to the prevailing environment. Here, we present ...
