Cod in a changing climate Match-mismatch and Threshold for the North Sea cod recruitment
Durant, Joël M.; Hjermann, Dag Ø.; Stenseth, Nils Christian; Beaugrand, Grégory (ICES CM documents;2005 / AA:01, Working paper, 2005)Climatic changes are disrupting otherwise tight trophic interactions between predator and prey. Most of the earlier studies have primarily focused on the temporal dimension of the relationship in the framework of the ... -
Evidence for effects on the North Sea ecosystem due to varying oceanic inflow over the last 100 years
Reid, Philip; Edwards, Martin; Beaugrand, Grégory; Skogen, Morten D.; Stevens, Darren (ICES CM Documents;2002/Q:8, Working paper, 2002)Oceanic inflow is estimated to contribute more than 90% of the nutrient input into the North Sea (NSTF, 1993). Variability in the volume, chemical properties, biological content and source of the inflowing water is thus ... -
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 ... -
Spawning stock and recruitment in North Sea cod shaped by food and climate
Olsen, Esben Moland; Ottersen, Geir; Llope, Marcos; Chan, Kung-Sik; Beaugrand, Grégory; Stenseth, Nils Christian (Journal article; Peer reviewed, 2010-09-01)In order to provide better fisheries management and conservation decisions, there is a need to discern the underlying relationship between the spawning stock and recruitment of marine fishes, a relationship which is ... -
