A comparison of biological trends from four marine ecosystems: synchronies, differences, and commonalities
Link, Jason S.; Stockhausen, William; Skaret, Georg; Overholtz, William; Megrey, Bernard A.; Gjøsæter, Harald; Gaichas, Sarah; Dommasnes, Are; Falk-Petersen, Jannike; Aydin, Kerim; Kane, Joseph; Mueter, Franz; Friedland, Kevin; Hare, Jon (ICES CM documents;2007/D:09, Working paper, 2007) -
A comparison of community and trophic structure in five marine ecosystems based on energy budgets and system metrics
Gaichas, Sarah; Skaret, Georg; Falk-Petersen, Jannike; Link, Jason S.; Overholtz, William; Megrey, Bernard A.; Gjøsæter, Harald; Stockhausen, William; Dommasnes, Are; Friedland, Kevin; Aydin, Kerim (ICES CM documents;2007/D:11, Working paper, 2007)As part of the international MENU collaboration, energy budget models for five marine ecosystems were compared to identify differences and similarities in trophic and community characteristics across ecosystems. We examined ... -
A cross-ecosystem comparison of temporal variability in recruitment of functionally analogous fish stocks
Megrey, Beatriz Diaz; Hare, Jon; Dommasnes, Are; Gjøsæter, Harald; Stockhausen, William; Overholtz, William; Gaichas, Sarah; Skaret, Georg; Falk-Petersen, Jannike; Link, Jason S.; Friedland, Kevin (ICES CM documents;2007/D:10, Working paper, 2007)As part of the international MENU collaboration, variability in temporal patterns of recruitment and spawning stock were compared among functionally analogous species from four marine ecosystems including the Gulf of ... -
Feeding ecology of Atlantic mackerel (Scomber scombrus) in the Norwegian Sea
Langøy, Herdis; Nøttestad, Leif; Skaret, Georg; Broms, Cecilie; Fernö, Anders (ICES CM documents, Working paper, 2006)Previous studies on Atlantic mackerel (Scomber scombrus) feeding during the highly migratory summer period are scarce. In this study we present detailed diet analyses and investigations of prey selection for Atlantic ... -
How and why acoustic detectability and catchability of herring change with individual motivation and physiological state in a variable environment: a multi-scale study on a local herring population in southwestern Norway
Langård, Lise; Nøttestad, Leif; Johannessen, Arne; Fernö, Anders; Øvredal, Jan Tore; Skaret, Georg; Nilsson, Gro N.; Vabø, Rune (ICES CM documents, Working paper, 2006)The understanding of distribution and aggregation in herring (Clupea harengus) can be enhanced by integrated multi-scale studies in small ecosystems. Hydro-acoustics, underwater cameras, herring and predator gillnet samples ... -
Impact of herring spawning behaviour on acoustic abundance estimates
Skaret, Georg; Fernö, Anders; Nøttestad, Leif; Johannessen, Arne; Axelsen, Bjørn Erik (ICES CM documents, Working paper, 2001)Spawning dynamics of Norwegian spring spawning herring was studied in south western Norway 29 March to 3 April 2000 using hydroacoustics. The horizontal distribution of the spawning layers shifted in a south-easterly ... -
Spatial and temporal overlap and trophic interactions between Atlantic Saithe (Pollachius virens) and Norwegian spring spawning herring (Clupea harengus) on herring spawning grounds
Slotte, Aril; Runde, Arne; Skaret, Georg; Axelsen, Bjørn Erik; Fernö, Anders; Johannessen, Arne; Nøttestad, Leif; Øvredal, Jan Tore (ICES CM documents, Working paper, 2005)Atlantic saithe (Pollachius virens) and Norwegian spring-spawning herring (Clupea harengus) represent two of the most abundant and ecologically important fish species in the Northeast Atlantic. The two species co-occur ...
