Alternative responses to rare selection events are differentially vulnerable to changes in the frequency, scope, and intensity of environmental extremes
(Journal article; Peer reviewed, 2019)Extreme weather events are becoming more frequent, severe, and/or widespread as a consequence of anthropogenic climate change. While the economic and ecological implications of these changes have received considerable ... -
Among-river pattern in relative abundance of two salmonid fishes reflects temperature-dependent competition
(Journal article; Peer reviewed, 2024)Temperature is a key driver in determining species distribution and abundance across climatic and geographical gradients. This occurs through direct physiological effects of temperature on performance, but may also result ... -
An assessment of critical steps in cultivating Palmaria palmata in Norwegian waters
(Master thesis, 2022)Makroalger som et bærekraftig alternativ har de siste tiårene fått økt oppmerksomhet da de har vist stort potensiale med mange bruksområder. Rødalgen Palmaria palmata er en av artene som har fått økt fokus grunnet dens ... -

An assessment of gains in conservation: A case study in Sør-Trøndelag, Norway
(Master thesis, 2012)SummaryForest ecosystems are important due to the services they are providing (e.g. food, timber, water and air clearance, etc.). This study investigated the change of forest habitat representation in the protected area ... -
An experimental test of optimal sampling behaviour in Siberian jays (Perisoreus infaustus)
(Master thesis, 2010)Optimal foraging models tend to assume that animals have perfect information. However, the world is constantly changing, and so it is likely that animals benefit from gathering better knowledge much of the time. Therefore, ... -
An ice-tethered buoy for fish and plankton research
(Chapter, 2018)I.In this paper the authors present bio-acoustical icetethered platform for optical, physical and ecological sensors (POPE), i.e. an ice-tethered buoy, equipped with an AZFP scientific echosounder for fish and plankton ... -
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 ... -
