Recruitment of Atlantic cod stocks in relation to temperature and advection of copepod populations
Sundby, Svein (Journal article; Peer reviewed, 2000-11)The recruitment of Atlantic cod stocks shows different responses to temperature changes. Cod stocks inhabiting the lower temperature range show generally an increase in recruitment with increasing temperature, while cod ... -

Spatial dynamics of the bearded goby and its key fish predators off Namibia vary with climate and oxygen availability
Salvanes, Anne Gro V.; Bartholomae, Chris; Yemane, Dawit; Gibbons, Mark J.; Kainge, Paul; Krakstad, Jens-Otto; Rouault, Mathieu; Staby, Arved; Sundby, Svein (Journal article; Peer reviewed, 2015-02-06)Hypoxia [O2 < 2.0 mL L−1 (87 μmol kg−1)] and severely hypoxic water masses [O2 < 0.5 mL L−1 (21.8 μmol kg−1)] are increasing in coastal marine ecosystems due to eutrophication and warming. Here, we investigate the response ... -
Spatial shifts in spawning habitats of Arcto-Norwegian cod related to multidecadal climate oscillations and climate change
Sundby, Svein; Nakken, Odd (Journal article; Peer reviewed, 2008-06-02)Arcto-Norwegian cod tend to produce strong year classes in warm years and poor year classes in cold years. This work shows that spawning intensity at various spawning sites along 1500 km of Norwegian coast is also influenced ... -
