    • Bridging marine ecosystem and biogeochemistry research: Lessons and recommendations from comparative studies 

      Salihoglu, B.; Neuer, S.; Painting, S.; Murtugudde, R.; Hofmann, E.E.; Steele, J.H.; Hood, R.R.; Legendre, L.; Lomas, M.W.; Wiggert, J.D.; Ito, S.; Lachkar, Z.; Hunt, George; Drinkwater, Ken; Sabine, L. (Journal article; Peer reviewed, 2012-07-13)
      There is growing interest in linking marine biogeochemistry with marine ecosystems research in response to the increasing need to understand and predict the effect of global change on the marine ecosystem. Such a holistic ...

    • Effects of mortality changes on biomass and production in Calanus spp. populations 

      Skarðhamar, Jofrid; Reigstad, Marit; Carroll, JoLynn; Eiane, Ketil; Riser, Christian Wexels; Slagstad, Dag (Journal article; Peer reviewed, 2011-04-28)
      Calanus species are the main link between primary producers and higher trophic-level organisms in the Barents Sea. The natural mortality rate is an essential parameter for determining the standing stock of Calanus, but it ...

    • Extension of the match-mismatch hypothesis to predator-controlled systems 

      Durant, Joël M.; Hjermann, Dag Ø.; Falkenhaug, Tone; Gifford, Dian J.; Naustvoll, Lars-Johan; Sullivan, Barbara K.; Beaugrand, Grégory; Stenseth, Nils Christian (Journal article; Peer reviewed, 2013-01-31)
      Differential change in the phenology of predators and prey is a potentially important climate-mediated mechanism influencing populations. The match-mismatch hypothesis describes the effect of predator-prey population ...

    • North Sea sensitivity to atmospheric forcing 

      Skogen, Morten D.; Drinkwater, Ken; Hjøllo, Solfrid Sætre; Schrum, Corinna (Journal article; Peer reviewed, 2011-04)
      The sensitivity of North Sea physics and phytoplankton production to atmospheric forcing has been studied by performing perturbations of the atmospheric forcing fields through a number of model simulations. The perturbations ...

    • Spatial variability of the plankton trophic interaction in the North Sea: a new feature after the early 1970s 

      Llope, Marcos; Licandro, Priscilla; Chan, Kung-Sik; Stenseth, Nils Christian (Journal article; Peer reviewed, 2011-08-24)
      Traditionally, marine ecosystem structure was thought to be bottom-up controlled. In recent years, a number of studies have highlighted the importance of top-down regulation. Evidence is accumulating that the type of trophic ...

    • The three-dimensional prey field of the northern krill, Meganyctiphanes norvegica, and the escape responses of their copepod prey 

      Abrahamsen, Mari B.; Browman, Howard I.; Fields, David M.; Skiftesvik, Anne Berit (Journal article; Peer reviewed, 2010-02-24)
      In the north Atlantic, Meganyctiphanes norvegica feeds predominantly on copepods, including Calanus spp. To quantify its perceptual field for prey, and the sensory systems underlying prey detection, the responses of tethered ...
