      Atlantic cod (Gadus morhua) is a large, cold-adapted teleost that sustains long-standing commercial fisheries and incipient aquaculture. Here we present the genome sequence of Atlantic cod, showing evidence for complex ...
    • High-throughput metabarcoding of eukaryotic diversity for environmental monitoring of offshore oil-drilling activities 

      Lanzén, Anders; Lekang, Katrine; Jonassen, Inge; Thompson, Eric; Troedsson, Christofer (Peer reviewed; Journal article, 2016-09)
      As global exploitation of available resources increases, operations extend towards sensitive and previously protected ecosystems. It is important to monitor such areas in order to detect, understand and remediate environmental ...
    • Metagenomic analysis of ammonia-oxidizing archaea affiliated with the soil group 

      Bartossek, Rita; Spang, Anja; Weidler, Gerhard; Lanzén, Anders; Schleper, Christa Maria (Peer reviewed; Journal article, 2012-06-20)
      Ammonia-oxidizing archaea (AOA) have recently been recognized as a significant compo- nent of many microbial communities and represent one of the most abundant prokaryotic groups in the biosphere. H owever, only few AOA ...
    • Novel and Unexpected Microbial Diversity in Acid Mine Drainage in Svalbard (78° N), Revealed by Culture-Independent Approaches 

      Garcia-Moyano, Antonio; Austnes, Andreas Erling; Lanzén, Anders; Gonzalez-Toril, Elena; Aguilera, Ángeles; Øvreås, Lise (Peer reviewed; Journal article, 2015-10-13)
