A systemic study of lipid metabolism regulation in salmon fingerlings and early juveniles fed plant oil
(Journal article; Peer reviewed, 2018)In salmon farming, the scarcity of fish oil has driven a shift towards the use of plant-based oil from vegetable or seed, leading to fish feed low in long-chain PUFA (LC-PUFA) and cholesterol. Atlantic salmon has the ... -
A tale of stress, reproduction, survival and climate change - Case study of the Norwegian Arctic fox (Vulpes lagopus) and measurement of glucocorticoids
(Master thesis, 2020)Klimaendringer setter arktik tundra under press; klimasensitive arter som gnagere kan få syklusen sin forstyrret som et resultat. Gnagere er for de fleste arktiske kjøttetere og omnivore en viktig del av deres diet. Når ... -
A targeted mass spectrometry immunoassay to quantify osteopontin in fresh-frozen breast tumors and adjacent normal breast tissues
(Journal article; Peer reviewed, 2019)Osteopontin (OPN) is a multifunctional protein that can activate cell-signaling pathways and lead to cancer development and metastasis. Elevated OPN expression was reported in different cancer types, including breast tumors. ... -
A test of priority effect persistence in semi-natural grasslands through the removal of plant functional groups during community assembly
(Journal article; Peer reviewed, 2016)Background:It is known that during plant community assembly, the early colonizing species can affect the estab-lishment, growth or reproductive success of later arriving species, often resulting in unpredictable assembly ... -
A unified framework for analysis of individual-based models in ecology and beyond
(Journal article; Peer reviewed, 2019)Individual-based models,‘IBMs’, describe naturally the dynamics of interacting organisms orsocial orfinancial agents. They are considered too complex for mathematical analysis, butcomputer simulations of them cannot give ... -
A Versatile and Robust Serine Protease Inhibitor Scaffold from Actinia tenebrosa
(Journal article; Peer reviewed, 2019)Serine proteases play pivotal roles in normal physiology and a spectrum of patho-physiological processes. Accordingly, there is considerable interest in the discovery and design of potent serine protease inhibitors for ... -
A veterinary perspective on One Health in the Arctic
(Journal article; Peer reviewed, 2017)Exposure to long-range transported industrial chemicals, climate change and diseases is posing a risk to the overall health and populations of Arctic wildlife. Since local communities are relying on the same marine food ... -
Abundance of planktonic sea lice in intensive sea farm locations at Frøya: January-September 2018
(Master thesis, 2019)Lepeiophtheirus salmonis og Caligus elongatus er dei to artane av havlus som som utgjer det største trugsmålet mot lakseoppdrett og villaks i Norge. Spreiing av lusa skjer hovudsakleg i planktoniske stadium. Kunnskap om ... -
Access and openness in biotechnology research collaborations between universities and industry
(Peer reviewed; Journal article, 2019)Biotechnology research can spawn broadly useful technology research platforms such as CRISPR/Cas9, which has frequently been criticised as a knowledge monopoly. The access to such technology can be restricted, and utilisation ... -
Acclimation capacity of critical thermal maximum varies among populations: Consequences for estimates of vulnerability
(Peer reviewed; Journal article, 2023)Adaptive plasticity in thermal tolerance traits may buffer organisms against changing temperatures, making such responses of particular interest in the face of global climate change. Although population variation is integral ... -
Acclimation Potential to a Future Ocean Acidification Scenario in the Key Copepod Species Calanus finmarchicus: - with emphasis on the genetic contribution to the acclimation response
(Master thesis, 2014)Ocean acidification, as a result of the increased concentration of carbon dioxide in the ocean, poses a threat towards marine ecosystems through lowered pH and altered seawater chemistry. The marine copepod Calanus ... -
Accounting for interspecific competition and age structure in demographic analyses of density dependence improves predictions of fluctuations in population size
(Peer reviewed; Journal article, 2019)Understanding species coexistence has long been a major goal of ecology. Coexistence theory for two competing species posits that intraspecific density dependence should be stronger than interspecific density dependence. ... -
Accounting for phylogenetic relatedness in cross-species analyses of telomere shortening rates
(Journal article; Peer reviewed, 2020)Telomeres are repeating DNA sequences found on the ends of chromosomes, which shorten with age and are implicated in senescence. Cross-species analyses of telomere shortening rates (TSR) and telomere lengths are important ... -
Accounting for Uncertainties in Biodiversity Estimations: A New Methodology and Its Application to the Mesopelagic Sound Scattering Layer of the High Arctic
(Peer reviewed; Journal article, 2022)Measures of biological diversity (biodiversity) are important for monitoring the state of ecosystems. Several indices and methods are used to describe biodiversity from field observations. Marine faunal biodiversity is ... -
Accumulation of (Ag(I) by Saccharomyces cereviseae cells expressing plant metallothioneins
(Journal article; Peer reviewed, 2018)The various applications of Ag(I) generated the necessity to obtain Ag(I)-accumulating organisms for the removal of surplus Ag(I) from contaminated sites or for the concentration of Ag(I) from Ag(I)-poor environments. In ... -
Accumulation of Gadolinium in organs of lumpfish (Cyclopterus lumpus)
(Master thesis, 2023)Sjeldne jordarter, også kjent som rare earth elements (REE) er grunnstoffer som vekker økende bekymring som forurensningskilder. Økt menneskelig bruk av REE har ført til rapportering av økte REE konsentrasjoner i naturen, ... -
Acid-base regulation and metabolite responses in shallow- and deep-living marine invertebrates during environmental hypercapnia
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:180, Doctoral thesis, 2012)Global warming is considered to be the most adverse consequence from the increasing anthropogenic emissions of CO2. However, in the marine environment additional problems related to the elevated levels atmospheric CO2 may ... -
Acute and physical effects of water-based drilling mud in the marine copepod Calanus finmarchicus
(Journal article; Peer reviewed, 2017)The aim of this study was to investigate impacts of fine particulate fraction of a commonly used barite-containing drilling mud on the pelagic filter feeding copepod Calanus finmarchicus. The results show that the tested ... -
Acute hydrogen peroxide (H2O2) exposure does not cause oxidative stress in late-copepodite stage of Calanus finmarchicus
(Journal article; Peer reviewed, 2017)Use of hydrogen peroxide (H2O2) for removal of salmon lice in the aquaculture industry has created concern that non-target organisms might be affected during treatment scenarios. The aim of the present study was to examine ... -
