Marine mammal consumption and fisheries removals in the Nordic and Barents Seas
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-28)In this study, we assess prey consumption by the marine mammal community in the northeast Atlantic [including 21 taxa, across three regions: (I) the Icelandic shelf, Denmark Strait, and Iceland Sea (ICE); (II) the Greenland and Norwegian Seas (GN); and (III) the Barents Sea (BS)], and compare mammal requirements with removals by fisheries. To determine prey needs, estimates of energetic requirements ... -
Modelled drift patterns of fish larvae link coastal morphology to seabird colony distribution
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-13)Colonial breeding is an evolutionary puzzle, as the benefits of breeding in high densities are still not fully explained. Although the dynamics of existing colonies are increasingly understood, few studies have addressed the initial formation of colonies, and empirical tests are rare. Using a high-resolution larval drift model, we here document that the distribution of seabird colonies along the ... -
Prey density in non-breeding areas affects adult survival of black-legged kittiwakes Rissa tridactyla
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-08-27)In migratory birds, environmental conditions in both breeding and non-breeding areas may affect adult survival rates and hence be significant drivers of demographic processes. In seabirds, poor knowledge of their true distribution outside the breeding season, however, has severely limited such studies. This study explored how annual adult survival rates of black-legged kittiwakes Rissa tridactyla ... -
The role of marine mammals in the Barents Sea foodweb
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-26)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 marine mammals. As a group, they directly connect to the most central species (i.e cod and haddock) in the Barents Sea (i.e. cod and haddock) and consume over half of the available ... -
Seafood production in Northern Norway: Analyzing variation and co-development in aquaculture and coastal fisheries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-27)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 development of the country and help sustain coastal communities, particularly, in Northern Norway. Coastal fishery has been the staple industry in Northern Norway for centuries, while ... -
Sjøfugl og marine økosystemer. Status for sjøfugl og sjøfuglenes næringsgrunnlag i Norge og på Svalbard
(Research report; Forskningsrapport, 2015)Denne synteserapporten beskriver hvordan endringene og fluktuasjonene i økosystemene i norske havområder påvirker næringsforholdene for sjøfugl. Disse endringene har konsekvenser for sjøfuglsamfunnene langs kysten, og tilstanden for mange bestander har blitt betegnet som kritisk. Selv om mange bestander går tilbake, er bildet langt fra entydig, og vi finner ingen enkle sammenhenger mellom tilstanden ... -
Spatio-temporal turnover and drivers of bentho-demersal community and food web structure in a high-latitude marine ecosystem
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-14)Aim: 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.<p> <p>Location: Barents Sea. <p>Method: We analysed data of benthic and bentho-pelagic fish and megabenthic invertebrates caught in the Barents Sea ecosystem survey in August–Septem ... -
Successive extreme climatic events lead to immediate, large-scale, and diverse responses from fish in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-06)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 (ECEs) are poorly understood. Here, we investigate the ecological signatures of three successive bottom temperature maxima concomitant with surface ECEs between 2004 and 2017 in ...
