(Rapport fra havforskningen;2024 - 38, Research report, 2024)På oppdrag for prosjektet «Bevar Raet» har av forskningsinstituttet utarbeidet en rapport om kunnskapsstatus for sjøområdene i og rundt Raet nasjonalpark. Formålet med rapporten er å bidra med et kunnskapsgrunnlag for at ... -
Rainbow trout Oncorhynchus mykiss skin responses to salmon louse Lepeophtheirus salmonis: From copepodid to adult stage
(Peer reviewed; Journal article, 2020)The marine crustacean Lepeophtheirus salmonis (salmon louse) is a common ectoparasite of wild and farmed salmonids. The parasite has a complex ontogeny comprising eight instars. The planktonic copepodid stage settles on ... -
Random effects modeling in fisheries science using AD Model Builder

A ranking method of chemical substances in foods for prioritisation of monitoring, based on health risk and knowledge gaps
(Peer reviewed; Journal article, 2020)Chemical contaminants are present in all foods. Data on the occurrence of contaminants in foods that are often consumed or contain high contaminant concentrations are critical for the estimation of exposure and evaluation ... -
Ranking of substances for monitoring in foods, drinks and dietary supplements - based on risk and knowledge gaps
(VKM Report, Research report, 2019) -
A rapid acid hydrolysis method for the determination of chitin in fish feed supplemented with black soldier fly (Hermetia illucens) larvae
(Peer reviewed; Journal article, 2022)Insects are a natural source of feed for fish and have received more attention as a potential source of sustainable high-quality protein. However, contrasting results in different feeding trials have been ascribed to the ... -
Rapid climate-driven circulation changes threaten conservation of endangered north atlantic right whales
(Journal article; Peer reviewed, 2019)As climate trends accelerate, ecosystems will be pushed rapidly into new states, reducing the potential efficacy of conservation strategies based on historical patterns. In the Gulf of Maine, climate-driven changes have ... -
Rapid Coastal Survey in Norwegian Waters

Rapid Determination of Per- and Polyfluoroalkyl Substances (PFAS) in Harbour Porpoise Liver Tissue by HybridSPE®–UPLC®–MS/MS
(Peer reviewed; Journal article, 2021)A rapid hybrid solid phase extraction (HybridSPE®) protocol tailored to ultra-performance liquid chromatography–electrospray ionization tandem mass spectrometry (UPLC®–ESI–MS/MS) analysis was developed for the determination ... -
Rapid faunal colonization and recovery of biodiversityand functional diversity following eelgrass restoration
(Peer reviewed; Journal article, 2023)Seagrass meadows and their associated biodiverse assemblages have declined globally due to environmental and anthropogenic stressors. Restoration of these critical habitats has the potential to reverse coastal biodiversity ... -
Rapid fCO2 rise in the northern Barents Sea and Nansen Basin
(Peer reviewed; Journal article, 2023)Maps of surface water fugacity of CO2 (fCO2) over eastern Fram Strait, south-western Nansen Basin, and the north-western Barents Sea (73–84°N, 5–46°E) from September 1997 to December 2020 were made and used to investigate ... -
Rapid life-history evolution in a wild Daphnia pulex population in response to novel size-dependent predation
(Peer reviewed; Journal article, 2020)The effect of size-selective predation on prey communities and their traits is well documented, but the relative roles of genetic adaptation and phenotypic plasticity continue to be debated. We looked for evidence of genetic ... -
Rapid polymerase chain reaction–restriction fragment length polymorphism method for discrimination of the two Atlantic cryptic deep-sea species of scabbardfish
(Journal article; Peer reviewed, 2009-03)The present investigation provides an efficient diagnostic method based on polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) analysis to discriminate between two cryptic species of scabbardfish, ... -
Rapid respiratory responses of the deep-water sponge Geodia barretti exposed to suspended sediments
(Journal article; Peer reviewed, 2013-09-04)Sponges often dominate deep-water benthic faunal communities and can comprise up to 90% of the benthic biomass. Due to the large amount of water that they filter daily, sponges are an important link between benthic and ... -
Rapid temporal decline of mercury in Greenland halibut (Reinhardtius hippoglossoides)
(Peer reviewed; Journal article, 2021)Mercury (Hg) pollution in the ocean is an issue of global concern, however bioaccumulation regimes of this ubiquitous pollutant in marine apex predators have important knowledge gaps. Our fish length and stable isotope ... -
Rapid water temperature variations at the northern shelf of the Yellow Sea
