  • CREST – Classification Resources for Environmental Sequence Tags 

    Lanzén, Anders; Jørgensen, Steffen L.; Huson, Daniel H.; Gorfer, Markus; Grindhaug, Svenn Helge; Jonassen, Inge; Øvreås, Lise; Urich, Tim (Public Library of Science, 2012-11-08)
    Sequencing of taxonomic or phylogenetic markers is becoming a fast and efficient method for studying environmental microbial communities. This has resulted in a steadily growing collection of marker sequences, most notably ...
  • Evolution of temperature optimum in Thermotogaceae and the prediction of trait values of uncultured organisms 

    Dahle, Håkon; Hannisdal, Bjarte; Steinsbu, Bjørn Olav; Ommedal, Hege; Einen, Jørn; Jensen, Sigmund; Larsen, Øyvind; Øvreås, Lise; Norland, Svein (Springer Link, 2011-06-03)
    Quantitative characterization of the mode and rate of phenotypic evolution is rarely applied to prokaryotes. Here, we present an analysis of temperature optimum (Topt) evolution in the thermophilic family Thermotogaceae, which ...
  • Planctomycetes dominate biofilms on surfaces of the kelp Laminaria hyperborea 

    Bengtsson, Mia M.; Øvreås, Lise (BioMed Central, 2010)
    Background: Bacteria belonging to Planctomycetes display several unique morphological and genetic features and are found in a wide variety of habitats on earth. Their ecological roles in these habitats are still poorly ...
  • Response of Methanogens in Arctic Sediments to Temperature and Methanogenic Substrate Availability 

    Blake, Lynsay; Tveit, Alexander Tøsdal; Øvreås, Lise; Head, Ian M.; Gray, Neil (PLOS, 2015-06-17)
    Although cold environments are major contributors to global biogeochemical cycles, comparatively little is known about their microbial community function, structure, and limits of activity. In this study a microcosm based ...
  • Seasonal dynamics of bacterial biofilms on the kelp Laminaria hyperborea 

    Bengtsson, Mia M.; Sjøtun, Kjersti; Øvreås, Lise (Inter-Research, 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 ...
  • Utilization of kelp-derived carbon sources by kelp surface-associated bacteria 

    Bengtsson, Mia M.; Sjøtun, Kjersti; Storesund, Julia Endresen; Øvreås, Lise (Inter-Research, 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 ...
