Operationalising ODEMM risk assessment for Integrated Ecosystem Assessment scoping: Complexity vs. manageability
Pedreschi, Debbi; Niiranen, Susa; Skern-Mauritzen, Mette; Reid, David G. (Peer reviewed; Journal article, 2023)Integrated Ecosystem Assessments (IEA) require consideration of the full suite of pressures and impacts affecting ecosystems. However, capacity limitations often severely limit our ability to do everything that we want or ... -
Opportunities for advancing ecosystem-based management in a rapidly changing, high latitude ecosystem
Skern-Mauritzen, Mette; Olsen, Erik Joel Steinar; Huse, Geir (Journal article; Peer reviewed, 2018)Unprecedented and rapid changes are ongoing in northern high latitude, marine ecosystems, due to climate warming. Species distributions and abundances are changing, altering both ecosystem structure and dynamics. At the ... -
Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids
Skern-Mauritzen, Rasmus; Sissener, Nini; Sandvik, Anne Dagrun; Meier, Sonnich; Sævik, Pål Næverlid; Skogen, Morten D.; Vågseth, Tone; Dalvin, Sussie; Skern-Mauritzen, Mette; Bui, Samantha (Peer reviewed; Journal article, 2020)The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ... -
Quantifying diets for small pelagic fish: effects of weight versus occurrence methods and sampling effort
Mousing, Erik Askov; Planque, Benjamin; Arneberg, Per; Bjørdal, Vilde Regine; Keulder-Stenevik, Felicia Juanita; Liebig, Penny Lee; Mørk, Herdis Langøy; Skern-Mauritzen, Mette (Peer reviewed; Journal article, 2023)In the Norwegian Sea, assessment of diet composition relies on annual cruise activity combined with visual identification and weight determination of prey from fish stomachs. This weight-based method is labour intensive, ... -
The role of marine mammals in the Barents Sea foodweb
Blanchet, Marie-Anne; Primicerio, Raul; Frainer, André; Kortsch, Susanne; Skern-Mauritzen, Mette; Dolgov, Andrey V.; Aschan, Michaela (Peer reviewed; Journal article, 2019)Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 ... -
Seafood production in Northern Norway: Analyzing variation and co-development in aquaculture and coastal fisheries
Espinasse, Marina; Mikkelsen, Eirik Inge; Sørbye, Sigrunn Holbek; Skern-Mauritzen, Mette; Falk-Andersson, Jannike; Fauchald, Per (Peer reviewed; Journal article, 2023)Norway is one of the leading ocean-based food production nations. Its seafood industry comprises wild-capture fisheries and farmed fish production. Both industries play a provisional role but also contribute to economic ... -
Sensitivity of the Norwegian and Barents Sea Atlantis end-to-end ecosystem model to parameter perturbations of key species
Hansen, Cecilie; Drinkwater, Kenneth F.; Jähkel, Anne; Fulton, Elizabeth A.; Gorton, Rebecca; Skern-Mauritzen, Mette (Journal article; Peer reviewed, 2019)Using end-to-end models for ecosystem-based management requires knowledge of the structure, uncertainty and sensitivity of the model. The Norwegian and Barents Seas (NoBa) Atlantis model was implemented for use in ‘what ... -
Spatio-temporal turnover and drivers of bentho-demersal community and food web structure in a high-latitude marine ecosystem
Pecuchet, Laurene; Jørgensen, Lis Lindal; Dolgov, Andreyv V.; Eriksen, Elena; Husson, Berengere; Skern-Mauritzen, Mette; Primicerio, Raul (Peer reviewed; Journal article, 2022)Assess the spatial and temporal turnover of bentho-demersal marine fauna by integrating ecological metrics at the community and food web levels and evaluate their main environmental and anthropogenic drivers. -
Successive extreme climatic events lead to immediate, large-scale, and diverse responses from fish in the Arctic
Husson, Berengere; Lind, Sigrid; Fossheim, Maria; Solvang, Hiroko Kato; Skern-Mauritzen, Mette; Pecuchet, Laurene; Ingvaldsen, Randi Brunvær; Dolgov, Andrey V.; Primicerio, Raul (Peer reviewed; Journal article, 2022)The warming trend of the Arctic is punctuated by several record-breaking warm years with very low sea ice concentrations. The nature and reversibility of marine ecosystem responses to these multiple extreme climatic events ... -
Temporal Dynamics of Top Predators Interactions in the Barents Sea
Durant, Joël M.; Skern-Mauritzen, Mette; Krasnov, Yuri V.; Nikolaeva, Natalia G.; Lindstrøm, Ulf; Dolgov, Andrey V. (Journal article; Peer reviewed, 2014-11-03)The Barents Sea system is often depicted as a simple food web in terms of number of dominant feeding links. The most conspicuous feeding link is between the Northeast Arctic cod Gadus morhua, the world's largest cod stock ... -
