    • Simple models combining competition, defence and resource availability have broad implications in pelagic microbial food webs 

      Våge, Selina; Bratbak, Gunnar; Egge, Jorun Karin; Heldal, Mikal; Larsen, Aud; Norland, Svein; Paulsen, Maria Lund; Pree, Bernadette; Sandaa, Ruth-Anne; Skjoldal, Evy Foss; Tsagaraki, Tatiana Margo; Øvreås, Lise; Thingstad, T. Frede (Peer reviewed; Journal article, 2018-09)
      In food webs, interactions between competition and defence control the partitioning of limiting resources. As a result, simple models of these interactions contain links between biogeochemistry, diversity, food web structure ...

    • Synechococcus in the Atlantic Gateway to the Arctic Ocean 

      Paulsen, Maria Lund; Doré, Hugo; Garczarek, Laurence; Seuthe, Lena; Müller, Oliver; Sandaa, Ruth-Anne; Bratbak, Gunnar; Larsen, Aud (Peer reviewed; Journal article, 2016-10-05)
      Increasing temperatures, with pronounced effects at high latitudes, have raised questions about potential changes in species composition, as well as possible increased importance of small-celled phytoplankton in marine ...

    • Viral infection switches the balance between bacterial and eukaryotic recyclers of organic matter during coccolithophore blooms 

      Vincent, Flora; Gralka, Matti; Schleyer, Guy; Schatz, Daniella; Cabrera-Brufau, Miguel; Kuhlisch, Constanze; Sichert, Andreas; Vidal-Melgosa, Silvia; Mayers, Kyle; Barak-Gavish, Noa; Flores, J. Michel; Masdeu-Navarro, Marta; Egge, Jorun Karin; Larsen, Aud; Hehemann, Jan-Hendrik; Marrasé, Celia; Simó, Rafel; Cordero, Otto X.; Vardi, Assaf (Journal article; Peer reviewed, 2023)
      Algal blooms are hotspots of marine primary production and play central roles in microbial ecology and global elemental cycling. Upon demise of the bloom, organic carbon is partly respired and partly transferred to either ...

    • Virus infection of Haptolina ericina and Phaeocystis pouchetii implicates evolutionary conservation of programmed cell death induction in marine haptophyte-virus interactions 

      Ray, Jessica Louise; Haramaty, Liti; Thyrhaug, Runar; Fredricks, Helen F.; Van Mooy, Benjamin A.S.; Larsen, Aud; Bidle, Kay D.; Sandaa, Ruth-Anne (Peer reviewed; Journal article, 2014-05-05)
      The mechanisms by which phytoplankton cope with stressors in the marine environment are neither fully characterized nor understood. As viruses are the most abundant entities in the global ocean and represent a strong ...
