Sarre, Abdoulaye; Demarcq, Hervé; Keenlyside, Noel Sebastian; Krakstad, Jens-Otto; El Ayoubi, Salaheddine; Jeyid, Ahmed Mohamed; Faye, Saliou; Mbaye, Adama; Sidibeh, Momodou; Brehmer, Patrice (Journal article; Peer reviewed, 2024)Climate change is recognised to lead to spatial shifts in the distribution of small pelagic fish, likely by altering their environmental optima. Fish supply along the Northwest African coast is significant at both ... -
Spatial dynamics of the bearded goby and its key fish predators off Namibia vary with climate and oxygen availability
Salvanes, Anne Gro Vea; Bartholomae, Chris H.; Yemane, Dawit; Gibbons, Mark J.; Kainge, Paul; Krakstad, Jens-Otto; Roault, Mathieu; Staby, Arved; Sundby, Svein (Peer reviewed; Journal article, 2015-03)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 ... -
