    • Epiphytic diatom community structure and richness is determined by macroalgal host and location in the South Shetland Islands (Antarctica) 

      Burfeid-Castellanos, Andrea M.; Martín-Martín, Rafael P.; Kloster, Michael; Preckler, Carlos Angulo; Avila, Conxita; Beszteri, Bank (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-30)
      The marine waters around the South Shetland Islands are paramount in the primary production of this Antarctic ecosystem. With the increasing effects of climate change and the annual retreat of the ice shelf, the importance of macroalgae and their diatom epiphytes in primary production also increases. The relationships and interactions between these organisms have scarcely been studied in Antarctica, ...

    • First Evidence of the Toxin Domoic Acid in Antarctic Diatom Species 

      Olesen, Anna J.; Altenburger, Andreas; Beszteri, Bank (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-26)
      The Southern Ocean is one of the most productive ecosystems in the world. It is an area heavily dependent on marine primary production and serving as a feeding ground for numerous seabirds and marine mammals. Therefore, the phytoplankton composition and presence of toxic species are of crucial importance. Fifteen monoclonal strains of Pseudo-nitzschia subcurvata, a diatom species endemic to the ...
