Reproducing the virus‐to‐copepod link in Arctic mesocosms using host fitness optimization
Abstract 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 as a single plankton functional type (PFT) in dynamic food web models...
