Quantitative mismatch between empirical temperature-size rule slopes and predictions based on oxygen limitation
(Peer reviewed; Journal article, 2021)In ectotherms, adult body size commonly declines with increasing environmental temperature, a pattern known as the temperature-size rule. One influential hypothesis explaining this observation is that the challenge of ... -
Quantitative transcriptomics, and lipidomics in evaluating ovarian developmental effects in Atlantic cod (Gadus morhua) caged at a capped marine waste disposal site
(Peer reviewed; Journal article, 2020)In the present study, a previously capped waste disposal site at Kollevåg (Norway) was selected to study the effects of contaminant leakage on biomarkers associated with Atlantic cod (Gadus morhua) reproductive endocrinology ... -
Radiative forcing geoengineering causes higher risk of wildfires and permafrost thawing over the Arctic regions
(Journal article; Peer reviewed, 2024)Radiative forcing geoengineering is discussed as an intermediate solution to partially offset greenhouse gas-driven warming by altering the Earth’s energy budget. Here we use an Earth System Model to analyse the response ... -
Radiological detection of nephrocalcinosis in farmed Atlantic salmon Salmo salar L.

Rainfall seasonality predicts the germination behaviour of a tropical dry-forest vine
(Journal article; Peer reviewed, 2019)Seed dormancy is considered to be an adaptive strategy in seasonal and/or unpredictable environments because it prevents germination during climatically favorable periods that are too short for seedling establishment. ... -

Rapid Determination of Per- and Polyfluoroalkyl Substances (PFAS) in Harbour Porpoise Liver Tissue by HybridSPE®–UPLC®–MS/MS
(Journal article; Peer reviewed, 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 determination of thyroid hormones in blood plasma from Glaucous gulls and Baikal seals by HybridSPE®-LC-MS/MS
(Peer reviewed; Journal article, 2021)A rapid hybrid solid phase extraction (HybridSPE®) protocol tailored to liquid chromatography–electrospray ionization tandem mass spectrometry (LC–ESI–MS/MS) analysis, was developed for the determination of four thyroid ... -
Rapid development of brood-parasitic cuckoo embryos cannot be explained by increased gas exchange through the eggshell
(Journal article; Peer reviewed, 2014)Obligate avian brood parasites lay their eggs in hosts' nests and play no role in the provisioning of the progeny. Many parasites, including Cuculus cuckoos, hatch before their hosts and the altricial chick evicts hosts ... -
Rare earth element distribution in the ne Atlantic: Evidence for benthic sources, longevity of the seawater signal, and biogeochemical cycling
(Journal article; Peer reviewed, 2018)Seawater rare earth element (REE) concentrations are increasingly applied to reconstruct water mass histories by exploiting relative changes in the distinctive normalised patterns. However, the mechanisms by which water ... -
Rearing water treatment induces microbial selection influencing the microbiota and pathogen associated transcripts of cod (Gadus morhua) larvae.
(Journal article; Peer reviewed, 2018)We have previously shown that K-selection and microbial stability in the rearing water increases survival and growth of Atlantic cod (Gadus morhua) larvae, and that recirculating aquaculture systems (RAS) are compatible ... -
Recent immigrants alter the quantitative genetic architecture of paternity in song sparrows.
(Peer reviewed; Journal article, 2020)Quantifying additive genetic variances and cross-sex covariances in reproductive traits, and identifying processes that shape and maintain such (co)variances, is central to understanding the evolutionary dynamics of ... -
Receptor-mediated toxicity of the chemicals extracted and migrated from plastics.
(Master thesis, 2023)Plast er tilstede i alle aspekter av dagliglivet. Plast er komplekse blandinger av kjemikalier som enten er petroleumsbaserte eller biobaserte. Flere studier rapporterte virkningene og truslene fra plastbruk på det ... -
Recommendations for quantitative uncertainty consideration in ecology and evolution
(Peer reviewed; Journal article, 2023)Ecological and evolutionary studies are currently failing to achieve complete and consistent reporting of model-related uncertainty. We identify three key barriers – a focus on parameter-related uncertainty, obscure ... -
Reconstruction and Registration of three Bilateral Protocerebral Neurons in the Standard Brain Atlas of the Moth Heliothis virescens
(Master thesis, 2013)Insect behaviour is tightly connected to their ability to detect important sensory information from their environment. The tobacco moth Heliothis virescens moth follows airborne stimuli to acquire partners, food and suitable ... -
Recovery, body mass and buoyancy: a detailed analysis of foraging dive cycles in the European shag
(Peer reviewed; Journal article, 2021)Foraging dives in birds and mammals involve complex physiological and behavioural adaptations to cope with the breaks in normal respiration. Optimal dive strategies should maximize the proportion of time spent under water ... -
Recruitment dynamics of Periphylla periphylla in the Trondheimsfjord
(Master thesis, 2013)Periphylla periphylla (Péron and Lesueur 1809) is a deep sea coronate scyphomedusa distributed in all oceans of the world, where it is normally found in low abundances. Over the last decades, however, it has established ... -
Red and white chinook salmon (Oncorhynchus tshawytscha): Differences in the transcriptome profile of muscle, liver, and pylorus
(Journal article; Peer reviewed, 2020)Astaxanthin (Ax), the main carotenoid responsible for the distinct red flesh color in salmonids (Oncorhynchus, Salvelinus, Salmo, and Parahucho), is added to the diet of farmed fish at a substantial cost. Despite the great ... -
Red-listed vascular Plant Species in Sub-Alpine and Alpine Landscapes: How does Land-use affect their Distribution?
(Master thesis, 2012)A major threat to red-listed vascular plant species in semi-natural habitats is land use change. In this study the effect of land use on the distribution of red-listed vascular plant species was investigated in a protected ... -
Redefining the oceanic distribution of Atlantic salmon
(Peer reviewed; Journal article, 2021)Determining the mechanisms driving range-wide reductions in Atlantic salmon marine survival is hindered by an insufcient understanding of their oceanic ecology and distribution. We attached 204 pop-up satellite archival ...
