Bacterial community composition responds to changes in copepod abundance and alters ecosystem function in an Arctic mesocosm study
Tsagaraki, Tatiana Margo; Pree, Bernadette; Leiknes, Øystein; Larsen, Aud; Bratbak, Gunnar; Øvreås, Lise; Egge, Jorun Karin; Spanek, Roman; Paulsen, Maria Lund; Olsen, Yngvar; Vadstein, Olav; Thingstad, T. Frede (Peer reviewed; Journal article, 2018)Combining a minimum food web model with Arctic microbial community dynamics, we have suggested that top-down control by copepods can affect the food web down to bacterial consumption of organic carbon. Pursuing this ... -
Diatom frustules as a biomaterial: effects of chemical treatment on organic material removal and mechanical properties in cleaned frustules from two Coscinodiscus species
Romann, Julien Clement; Chauton, Mathilde Skogen; Hanetho, Sidsel Meli; Vebner, Marius; Heldal, Mikal; Thaulow, Christian; Vadstein, Olav; Tranell, Gabriella; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2016-08)The three-dimensional structure of silica diatom frustules offers a great potential as nanoporous material for several nanotechnological applications, but the starting point for these applications is the ability to obtain ... -
Mechanisms Generating Dichotomies in the Life Strategies of Heterotrophic Marine Prokaryotes
Thingstad, T. Frede; Øvreås, Lise; Vadstein, Olav (Journal article; Peer reviewed, 2022)Understanding the mechanisms that generate and maintain diversity in marine prokaryotic communities is one of the main challenges for contemporary marine microbiology. We here review how observational, experimental, and ...
