    • Mechanistic model identifies increasing light availability due to sea ice reductions as cause for increasing macroalgae cover in the Arctic 

      Scherrer, Kim Josefin Niklasdotter; Kortsch, Susanne; Varpe, Øystein; Weyhenmeyer, Gesa Antonie; Gulliksen, Bjørn; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-04)
      In the Arctic, rising seawater temperatures and increasing underwater light caused by reductions in sea ice cover are expected to change the structure of arctic marine communities. Substantial, sometimes sudden, increases in macroalgal productivity and biomass have already been observed in arctic rocky bottom communities. These macroalgal responses have been attributed to increasing temperature and ...

    • Screening for antibacterial and antifungal activities in marine benthic invertebrates from northern Norway 

      Tadesse, Margey; Gulliksen, Bjørn; Strøm, Morten B.; Styrvold, Olaf B.; Haug, Tor (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-06-18)
      Benthic marine invertebrates collected from sub-Arctic regions of northern Norway, were found to be a promising source of novel bioactive compounds against human and fish pathogenic bacteria and fungi. Lyophilized material from seven species of ascidians, six sponges and one soft alcyonid coral were extracted with 60% acidified acetonitrile (ACN). After separation into an ACN-rich phase (ACN extract) ...
