An integrated analysis of molecular acclimation to high light in the marine diatom Phaeodactylum tricornutum
(Journal article; Peer reviewed, 2009-11-03)Photosynthetic diatoms are exposed to rapid and unpredictable changes in irradiance and spectral quality, and must be able to acclimate their light harvesting systems to varying light conditions. Molecular mechanisms behind ... -
An integrated population model for a long-lived ungulate: more efficient data use with Bayesian methods
(Journal article, 2015)We develop an integrated population model for Svalbard reindeer Rangifer tarandus platyrhynchus, and demonstrate how this type of model can be used to extract more information from the data and separate different sources ... -
An interspecific assessment of Bergmann’s rule in 22 mammalian families
(Journal article; Peer reviewed, 2016)Background: Bergmann’s rule proposes that animals in cold habitats will be larger than those in warm habitats. This prediction has been tested thoroughly at the intraspecific level, but few studies have investigated the ... -
An investigation into animal personality in early benthic phase European lobster (Homarus gammarus)
(Master thesis, 2016)Consistent individual differences in behavior, also known as animal personality, have been described across a wide range of taxa. In this study, evidence for animal personality was investigated in the European lobster, an ... -
An investigation of biofouling and its management in Norwegian salmon aquaculture, and the potential effects on cleaner fish behaviour
(Master thesis, 2020)Det høyfrekvente notvaskregimet i norsk lakseoppdrett, som er sterkt drevet av å sikre avlusningseffekten og appettitten for lus hos rensefisk, har store negative konsekvenser for merdmiljøet, fiskehelse \& velferd og ... -
An oil containing EPA and DHA from transgenic Camelina sativa to replace marine fish oil in feeds for Atlantic salmon (Salmo salar L.): Effects on intestinal transcriptome, histology, tissue fatty acid profiles and plasma biochemistry
(Journal article; Peer reviewed, 2017)New de novo sources of omega 3 (n-3) long chain polyunsaturated fatty acids (LC-PUFA) are required as alternatives to fish oil in aquafeeds in order to maintain adequate levels of the beneficial fatty acids, eicosapentaenoic ... -
Anaesthetic efficacy of Aqui-S, Benzoak, and MS-222 on lumpfish (Cyclopterus lumpus) fries. Impact from temperature, salinity, and fasting
(Journal article; Peer reviewed, 2019)Large numbers of lumpfish are produced for the Norwegian salmon industry and are used to combat sea lice infestations. Periodically high mortality of farmed lumpfish demonstrates the need to improve farming conditions and ... -
Analyses of charophyte chloroplast genomes help characterize theancestral chloroplastgenomeof land plants
(Journal article; Peer reviewed, 2014)Despite the significance of the relationships between embryophytes and their charophyte algal ancestors in deciphering the origin and evolutionary success of land plants, few chloroplast genomes of the charophyte algae ... -
Analysis and comparision of Transcription Factor - Target Gene databases using network analysis. - The gene regulatory network documented on the basis of experimental evidence is analysed and compared by the graph based analysis method of various resources of gene regulatory network available from various public resource database is performed.
(Master thesis, 2014)Gene regulatory network assembly and analysis requires high quality knowledge sources that cover functional aspect of various components of the gene regulatory machinery. Transcription factor constitutes key gene regulatory ... -
Analysis of Plastic Associated Chemicals in Cinereous Vultures (Aegypius monachus).
(Master thesis, 2023)Sammendrag Plast er en oppfinnelse av vitenskap og teknologi som er nært knyttet til våre moderne liv. Uansett hvilket aspekt vi referer til, har plast en betydelig innflytelse som gjør ting enklere, raskere og billigere. ... -
Analysis of polyphenols and cyclic compounds in plants using derivatization techniques in combination with GC-MS-based metabolite profiling
(Journal article; Peer reviewed, 2015)Metabolite profiling has been established as a modern technology platform for the description of complex chemical matrices and compound identification in biological samples. Gas chromatography coupled with mass spectrometry ... -
Analysis of the Drug Target Combination space of the AGS cancer model CASCADE 1.0 and the generic cancer model CASCADE 2.0
(Master thesis, 2022)Logical models are a promising method to predict the drug combinations without testing the massive number of possible combinations experimentally. In this project we analyzed two logical models the AGS cancer model CASCADE ... -
Analyzing dynamic species abundance distributions using generalized linear mixed models
(Peer reviewed; Journal article, 2022)Understanding the mechanisms of ecological community dynamics and how they could be affected by environmental changes is important. Population dynamic models have well known ecological parameters that describe key ... -
Analyzing the Impacts of Elevated-CO2 Levels on the Development of a Subtropical Zooplankton Community During Oligotrophic Conditions and Simulated Upwelling
(Journal article; Peer reviewed, 2019)Ocean acidification (OA) is affecting marine ecosystems through changes in carbonate chemistry that may influence consumers of phytoplankton, often via trophic pathways. Using a mesocosm approach, we investigated OA effects ... -
Anchoring plant metallothioneins to the inner face of the plasma membrane of Saccharomyces cerevisiae cells leads to heavy metal accumulation
(Journal article; Peer reviewed, 2017)In this study we engineered yeast cells armed for heavy metal accumulation by targeting plant metallothioneins to the inner face of the yeast plasma membrane. Metallothioneins (MTs) are cysteine-rich proteins involved in ... -
Ancient origin and maternal inheritance of blue cuckoo eggs
(Journal article; Peer reviewed, 2016)Maternal inheritance via the female-specific W chromosome was long ago proposed as a potential solution to the evolutionary enigma of co-existing host-specific races (or ‘gentes’) in avian brood parasites. Here we report ... -
