Contrasting response to nutrient manipulation in Arctic mesocosms are reproduced by a minimum microbial food web model
Larsen, Aud; Egge, Jorun Karin; Nejstgaard, Jens Christian; Di Capua, Iole; Thyrhaug, Runar; Bratbak, Gunnar; Thingstad, Tron Frede (Peer reviewed; Journal article, 2015-01-27)A minimum mathematical model of the marine pelagic microbial food web has previously shown to be able to reproduce central aspects of observed system response to different bottom-up manipulations in a mesocosm experiment ... -
Microbial communities and processes in ice-covered Arctic waters of the northwestern Fram Strait (75 to 80° N) during the vernal pre-bloom phase
Seuthe, Lena; Töpper, Birte; Reigstad, Marit; Thyrhaug, Runar; Vaquer-Sunyer, Raquel (Peer reviewed; Journal article, 2011-09-20)Marine microbial communities have been little studied in Arctic waters, especially during the winter–spring transition before the development of extensive phytoplankton blooms. This study investigated microbial plankton ... -
The Response of Heterotrophic Prokaryote and Viral Communities to Labile Organic Carbon Inputs Is Controlled by the Predator Food Chain Structure
Sandaa, Ruth-Anne; Pree, Bernadette; Larsen, Aud; Våge, Selina; Tøpper, Birte; Töpper, Joachim Paul; Thyrhaug, Runar; Thingstad, Tron Frede (Peer reviewed; Journal article, 2017-08-23)Factors controlling the community composition of marine heterotrophic prokaryotes include organic-C, mineral nutrients, predation, and viral lysis. Two mesocosm experiments, performed at an Arctic location and bottom-up ... -
Virus infection of Haptolina ericina and Phaeocystis pouchetii implicates evolutionary conservation of programmed cell death induction in marine haptophyte-virus interactions
Ray, Jessica Louise; Haramaty, Liti; Thyrhaug, Runar; Fredricks, Helen F.; Van Mooy, Benjamin A.S.; Larsen, Aud; Bidle, Kay D.; Sandaa, Ruth-Anne (Peer reviewed; Journal article, 2014-05-05)The mechanisms by which phytoplankton cope with stressors in the marine environment are neither fully characterized nor understood. As viruses are the most abundant entities in the global ocean and represent a strong ...
