      Hestetun, Jon Thomassen; Dahle, Håkon; Jørgensen, Steffen Leth; Olsen, Bernt Rydland; Rapp, Hans Tore (Peer reviewed; Journal article, 2016-11-09)
      As shown by recent studies, filter-feeding sponges are known to host a wide variety of microorganisms. However, the microbial community of the non-filtering carnivorous sponges (Porifera, Cladorhizidae) has been the subject ...
    • Nitrifier abundance and diversity peak at deep redox transition zones 

      Zhao, Rui; Hannisdal, Bjarte; Mogollon, Josè M.; Jørgensen, Steffen Leth (Peer reviewed; Journal article, 2019-06-14)
      More than half of the global ocean floor is draped by nutrient-starved sediments characterized by deep oxygen penetration and a prevalence of oxidized nitrogen. Despite low energy availability, this habitat hosts a vast ...
