    • Seasonal dynamics of bacterial biofilms on the kelp Laminaria hyperborea 

      Bengtsson, Mia M.; Sjøtun, Kjersti; Øvreås, Lise (Peer reviewed; Journal article, 2010-05)
      Seasonal variations of the cell density and bacterial community composition in biofilms growing on the surface of the kelp Laminaria hyperborea from 2 sites on the southwestern coast of Norway were investigated using total ...

    • Sewage-based surveillance shows presence of Klebsiella pneumoniae resistant against last resort antibiotics in the population in Bergen, Norway 

      Radisic, Vera; Grevskott, Didrik Hjertaker; Lunestad, Bjørn Tore; Øvreås, Lise; Marathe, Nachiket (Journal article; Peer reviewed, 2022)
      The aim of this study was to understand the prevalence of antibiotic resistance in Klebsiella pneumoniae present in the population in Bergen city, Norway using city-scale sewage-based surveillance, as well as the potential ...

    • 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 ...

    • The summer bacterial and archaeal community composition of the northern Barents Sea 

      Thiele, Stefan; Vader, Anna; Thomson, Stuart; Saubrekka, Karoline; Petelenz-Kurdziel, Elzbieta Anna; Rief Armo, Hilde; Müller, Oliver; Olsen, Lasse Mork; Bratbak, Gunnar; Øvreås, Lise (Journal article; Peer reviewed, 2023)
      Climate change related alterations in the Arctic have influences on the marine ecosystems, in particular on phytoplankton bloom dynamics. Since phytoplankton blooms are the main provider of carbon sources to the microbial ...

    • Utilization of kelp-derived carbon sources by kelp surface-associated bacteria 

      Bengtsson, Mia M.; Sjøtun, Kjersti; Storesund, Julia Endresen; Øvreås, Lise (Peer reviewed; Journal article, 2011-01)
      The surfaces of kelp are covered with bacteria that may utilize kelp-produced carbon and thereby contribute significantly to the carbon flux in kelp forest ecosystems. There is scant knowledge about the identity of these ...

    • A winter-to-summer transition of bacterial and archaeal communities in Arctic sea ice 

      Thiele, Stefan; Storesund, Julia Endresen; Férnandez-Méndez, Mar; Assmy, Philipp; Øvreås, Lise (Journal article; Peer reviewed, 2022-08-15)
      The Arctic is warming 2–3 times faster than the global average, leading to a decrease in Arctic sea ice extent, thickness, and associated changes in sea ice structure. These changes impact sea ice habitat properties and ...
