Cod and climate: effect of the North Atlantic Oscillation on recruitment in the North Atlantic
Stige, Leif Christian; Ottersen, Geir; Brander, Keith; Chan, Kung-Sik; Stenseth, Nils Christian (Journal article; Peer reviewed, 2006-11-07)The impact of the environment on interannual variability in fish recruitment has proven difficult to establish empirically, and environment-recruitment correlations have often been found to break down when more data become ... -
Direct and indirect climate forcing in a multi-species marine system
Ottersen, Geir; Stige, Leif Christian; Dalpadado, Padmini; Chan, Kung-Sik; Hjermann, Dag Ø.; Lajus, Dmitry L.; Yaragina, Natalia A.; Stenseth, Nils Christian (Journal article; Peer reviewed, 2010-10)Interactions within and between species complicate quantification of climate effects, by causing indirect, often delayed, effects of climate fluctuations and compensation of mortality. Here we identify direct and indirect ... -
Population dynamics of cod Gadus morhua in the North Sea region: biological density-dependent and climatic density-independent effects
Chen, Qingxian; Chan, Kung-Sik; Lekve, Kyrre; Torstensen, Else; Gjøsæter, Jakob; Ottersen, Geir; Stenseth, Nils Christian (Journal article; Peer reviewed, 2005-11-04)Through the statistical modeling of monitoring data, we assess the ecological interlinkages between cod Gadus morhua L. in the North Sea, Skagerrak and Kattegat—regions which typically have been considered separate management ... -
Seasonal plankton dynamics along a cross-shelf gradient
Stenseth, Nils Christian; Llope, Marcos; Anadón, Ricardo; Ciannelli, Lorenzo; Chan, Kung-Sik; Hjermann, Dag Ø.; Bagøien, Espen; Ottersen, Geir (Journal article; Peer reviewed, 2006-08-08)Much interest has recently been devoted to reconstructing the dynamic structure of ecological systems on the basis of time-series data. Using 10 years of monthly data on phyto- and zooplankton abundance from the Bay of ... -
Spatial patterns of age-0 cod survival in the Barents Sea
Ciannelli, Lorenzo; Dingsør, Gjert Endre; Bogstad, Bjarte; Ottersen, Geir; Chan, Kung-Sik; Gjøsæter, Harald; Stenseth, Nils Christian (ICES CM documents, Working paper, 2005)Apart from human harvest, recruitment dynamics is conceivably recognized as the main source of population variability of marine fish stocks. Factors affecting recruitment dynamics can change over both temporal and spatial ... -
Spatial variability of the plankton trophic interaction in the North Sea: a new feature after the early 1970s
Llope, Marcos; Licandro, Priscilla; Chan, Kung-Sik; Stenseth, Nils Christian (Journal article; Peer reviewed, 2011-08-24)Traditionally, marine ecosystem structure was thought to be bottom-up controlled. In recent years, a number of studies have highlighted the importance of top-down regulation. Evidence is accumulating that the type of trophic ... -
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 ... -
