    • Centennial decline in North Sea water clarity causes strong delay in phytoplankton bloom timing 

      Opdal, Anders Frugård; Lindemann, Christian; Aksnes, Dag Lorents (Peer reviewed; Journal article, 2019-08-23)
      With climate warming, a widespread expectation is that events in spring, such as flowering, bird migrations, and insect bursts, will occur earlier because of increasing temperature. At high latitudes, increased ocean ...

    • Effects of migrating mesopelagic fishes on the biological carbon pump 

      Aksnes, Dag Lorents; Løtvedt, Anita Stene; Lindemann, Christian; Calleja, Maria Ll.; Morán, Xosé Anxelu G.; Kaartvedt, Stein; Thingstad, T. Frede (Journal article; Peer reviewed, 2023)
      Mesopelagic fishes and invertebrates contribute to the biological carbon pump (BCP) through direct and indirect effects on the gravitational, diffusive, and migrant (active) fluxes. Here, we analyzed the effect of these ...

    • Land use change and coastal water darkening drive synchronous dynamics in phytoplankton and fish phenology on centennial timescales 

      Opdal, Anders Martin Frugård; Lindemann, Christian; Andersen, Tom; Hessen, Dag Olav; Fiksen, Øyvind; Aksnes, Dag Lorents (Journal article; Peer reviewed, 2024)
      At high latitudes, the suitable window for timing reproductive events is particularly narrow, promoting tight synchrony between trophic levels. Climate change may disrupt this synchrony due to diverging responses to ...

    • Modelling approaches for capturing plankton diversity (MODIV), their societal applications and data needs 

      Acevedo-Trejos, Esteban; Cadier, Mathilde; Chakraborty, Subhendu; Chen, Bingzhang; Cheung, Shun Yan; Grigoratou, Maria; Guill, Christian; Hassenrück, Christiane; Kerimoglu, Onur; Klauschies, Toni; Lindemann, Christian; Palacz, Artur; Ryabov, Alexey; Scotti, Marco; Smith, S. Lan; Våge, Selina; Prowe, Friederike (Journal article; Peer reviewed, 2022)
      Ecosystem models need to capture biodiversity, because it is a fundamental determinant of food web dynamics and consequently of the cycling of energy and matter in ecosystems. In oceanic food webs, the plankton compartment ...

    • Scaling laws in phytoplankton nutrient uptake affinity 

      Lindemann, Christian; Fiksen, Øyvind; Andersen, Ken Haste; Aksnes, Dag Lorents (Peer reviewed; Journal article, 2016-03-11)
      Nutrient uptake affinity affects the competitive ability of microbial organisms at low nutrient concentrations. From the theory of diffusion limitation it follows that uptake affinity scales linearly with the cell radius. ...

    • Spawning fish maintains trophic synchrony across time and space beyond thermal drivers 

      Opdal, Anders Martin Frugård; Wright, Peter J.; Blom, Geir; Höffle, Hannes; Lindemann, Christian; Kjesbu, Olav Sigurd (Journal article; Peer reviewed, 2024)
      Increasing ocean temperature will speed up physiological rates of ectotherms. In fish, this is suggested to cause earlier spawning due to faster oocyte growth rates. Over time, this could cause spawning time to become ...

    • Tracking freshwater browning and coastal water darkening from boreal forests to the Arctic Ocean 

      Opdal, Anders Martin Frugård; Andersen, Tom; Hessen, Dag Olav; Lindemann, Christian; Aksnes, Dag Lorents (Journal article; Peer reviewed, 2023)
      The forest cover of Northern Europe has been steadily expanding during the last 120 years. More terrestrial vegetation and carbon fixation leads to more export to surface waters. This may cause freshwater browning, as more ...
