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 ... -
Future climate scenarios for a coastal productive planktonic food web resulting in microplankton phenology changes and decreased trophic transfer efficiency
Calbet, Albert; Sazhin, Andrey F.; Nejstgaard, Jens Christian; Berger, Stella Angela; Tait, Zachary S.; Olmos, Lorena; Sousoni, Despoina; Isari, Stamatina; Martinez, Rodrigo A.; Bouquet, Jean-Marie; Thompson, Eric; Båmstedt, Ulf; Jakobsen, Hans H. (Peer reviewed; Journal article, 2014-04-10)We studied the effects of future climate change scenarios on plankton communities of a Norwegian fjord using a mesocosm approach. After the spring bloom, natural plankton were enclosed and treated in duplicates with inorganic ... -
Reproducing the virus-to-copepod link in Arctic mesocosms using host fitness optimization.
Thingstad, T. Frede; Larsen, Aud; Bratbak, Gunnar; Våge, Selina; Egge, Jorun Karin; Sandaa, Ruth-Anne; Nejstgaard, Jens Christian (Journal article; Peer reviewed, 2020)By shunting material out of the predatory pathway toward detritus and dissolved material, viruses are believed to have an important impact on biogeochemical functions of the pelagic microbial food web. To include viruses ...
