• Ammonia-oxidizing archaea have similar power requirements in diverse marine oxic sediments 

      Zhao, Rui; Mogollon, Jose M; Roerdink, Desiree Lisette; Thorseth, Ingunn Hindenes; Økland, Ingeborg Elisabet; Jørgensen, Steffen Leth (Journal article; Peer reviewed, 2021)
      Energy/power availability is regarded as one of the ultimate controlling factors of microbial abundance in the deep biosphere, where fewer cells are found in habitats of lower energy availability. A critical assumption ...
    • Genomes of Thaumarchaeota from deep sea sediments reveal specific adaptations of three independently evolved lineages 

      Kerou, Melina; Ponce-Toledo, Rafael I.; Zhao, Rui; Abby, Sophie S.; Hirai, Miho; Nomaki, Hidetaka; Takaki, Yoshihiro; Nunoura, Takuro; Jørgensen, Steffen Leth; Schleper, Christa (Journal article; Peer reviewed, 2021)
      Marine sediments represent a vast habitat for complex microbiomes. Among these, ammonia oxidizing archaea (AOA) of the phylum Thaumarchaeota are one of the most common, yet little explored, inhabitants, which seem ...
    • The potential of sedimentary ancient DNA for reconstructingpast sea ice evolution 

      De Schepper, Stijn; Ray, Jessica Louise; Skaar, Katrine Sandnes; Sadatzki, Henrik; Ijaz, Umer Zeeshan; Stein, Ruediger; Larsen, Aud (Peer reviewed; Journal article, 2019-06-24)
      Sea ice is a crucial component of the Arctic climate system, yet the tools to document the evolution of sea ice conditions onhistorical and geological time scales are few and have limitations. Such records are essential ...
