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 ... -
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 ... -

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 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
(Peer reviewed; Journal article, 2021)During summer, there is great spatial variability in bottom water temperature on the northern shelf of the Yellow Sea. This variability is associated with a thermal front along the shelf. Oscillatory currents from semidiurnal ... -
Rapport om forsøksfiske etter kolmule vest av De Britiske Øyer i februar-mai 1973
(Journal article, 1973)The experiments were carried out with four boats. Two of a different size working as one boat midwater trawlers and two as a twoboat midwater trawl unit. It is concluded that the spawning stock is dense enough for commercial ... -

Rather-high-frequency sound scattering by swimbladdered fish
(Journal article; Peer reviewed, 1985)A new model describes acoustic scattering by swimbladdered fish of lengths from at least 8 to 36 wavelengths. It represents a fish by an ideal pressure-release surface having the exact size and shape as the swimbladder. ... -

Reaction norm analysis reveals rapid shifts toward delayed maturation in harvested Lake Erie yellow perch (Perca flavescens)
(Journal article; Peer reviewed, 2019)Harvested marine fish stocks often show a rapid and substantial decline in the age and size at maturation. Such changes can arise from multiple processes including fisheries‐induced evolution, phenotypic plasticity, and ... -
