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 ... -
Life-history evolution in response to foraging risk, modelled for Northeast Arctic cod (Gadus morhua)
Jessen, Henrik Høiberg; Opdal, Anders Martin Frugård; Enberg, Katja Susanna (Journal article; Peer reviewed, 2023)Foraging behaviour is known to be a key element in ecology and evolution. Increased foraging intensity increases energy intake, which is useful for growth and reproduction but comes at the cost of higher mortality risk due ... -
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 ...
