Ecotoxicological impacts of surface water and wastewater from conventional and advanced treatment technologies on brood size, larval length, and cytochrome P450 (35A3) expression in Caenorhabditis elegans
(Journal article; Peer reviewed, 2018)Anthropogenic micropollutants and transformation products (TPs) negatively affect aquatic ecosystems and water resources. Wastewater treatment plants (WWTP) represent major point sources for (micro)pollutants and TPs in ... -
Effect of Cadmium on the marine diatoms Seminavis robusta and Phaeodactylum tricornutum: A comparative study
(Master thesis, 2016)Background: Heavy metals cause a harmful effect on marine ecosystems because of their toxicity, persistence and bioaccumulation properties. Cadmium (Cd) is speculated to be a unique heavy metal due to its diverse toxic ... -
Effect of Calibration Data Subsetting on Boolean Model Calibration and Drug Synergy Predictions
(Master thesis, 2023)Kreft er et samlebegrep for en rekke sykdomstilstander som kjennetegnes av unormal og ukontrollert celledeling, og forårsakes av avvikende regulering av ulike cellulære signalveier knyttet til cellevekst og celledød. Med ... -
The effect of climate change on avian offspring production: A global meta-analysis
(Peer reviewed; Journal article, 2023)Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders ... -
Effect of diet on molecular relationships between Atlantic cod larval muscle growth dynamics, metabolism, and antioxidant defense system
(Peer reviewed; Journal article, 2022)We studied molecular effects (RNAseq and qPCR) of first feeding prey types (copepods or rotifers/Artemia) on skeletal muscle myogenesis and growth dynamics (proliferation, differentiation), metabolism (glycolysis, ... -
Effect of dietary ARA/EPA/DHA ratios on growth performance and intermediary metabolism of gilthead sea bream (Sparus aurata) juveniles
(Peer reviewed; Journal article, 2019)Vegetable oils (VO) are generally accepted as valuable alternatives to fish oils but are devoid of n-3 LC-PUFA (Long-Chain-Polyunsaturated Fatty Acids) and rich in C18-PUFA. Marine fish have limited capacity to express ... -
Effect of dietary components on the gut microbiota of aquatic animals. A never-ending story?
(Peer reviewed; Journal article, 2015)It is well known that healthy gut microbiota is essential to promote host health and well-being. The intestinal microbiota of endothermic animals as well as fish are classified as autochthonous or indigenous, when they are ... -
Effect of different dietary arachidonic, eicosapentaenoic, and docosahexaenoic acid content on selected immune parameters in gilthead sea bream (Sparus aurata)
(Peer reviewed; Journal article, 2021)The increasing replacement of fish oil (FO) by vegetable oils (VO) in aquafeeds for marine carnivorous species may lead to modifications of the dietary arachidonic (ARA), eicosapentaenoic (EPA) and docosahexaenoic (DHA) ... -
Effect of environmental factors on growth and development of Phaeodactylum tricornutum
(Master thesis, 2023)Diatoms are eukaryotic photosynthetic organisms found in marine and freshwater environments as primary producers accounting for ~20% of total world photosynthetic output and ~50% of oceanic biomass. Diatoms are of industrial ... -
Effect of experimentally increased adult foraging effort on the offspring in black legged kittiwakes (Rissa tridactyla)
(Master thesis, 2011)The Black legged Kittiwake (Rissa tridactyla) is one of the more extensively studied seagull species, and much of their nesting behaviour and physiology concerning the breeding period has already been examined to a high ... -
Effect of forest management history on understorey vegetation via changes in soil biota– A study of beech forests in Denmark
(Master thesis, 2023)Jordsmonn er et svært komplekst økosystem som globalt sett representerer det største karbonsluket, som hver for seg støtter omfattende nettverk av funksjonelt forskjellige biotiske samfunn, og som bidrar til 98 % av ... -
Effect of high dietary ARA and EPA on intestinal health of Atlantic salmon (Salmo salar) before and after chronic stress
(Master thesis, 2020)Redusert bruk av marine fettsyrer i fiskefôr har ført til en høyere n-6/n-3 fettsyresammensetning i vev og organer til Atlantisk laks (Salmo salar). Siden langkjedede flerumettede fettsyrer (LC-PUFA) har sentrale roller i ... -
Effect of human–elephant conflict on local attitudes toward the conservation of wild Asian elephants in Myanmar
(Peer reviewed; Journal article, 2022)The study of attitudes toward wild elephants and human–elephant conflict (HEC) is vital to understanding what attitudes are held by local people and how to incorporate them into wild elephant conservation. This study ... -
Effect of hydroxamate and catecholate siderophores on iron availability in the diatom Skeletonema costatum: Implications of siderophore degradation by associated bacteria
(Journal article; Peer reviewed, 2019)The bioavailability of iron (Fe) across marine ecosystems, mainly determined by Fe speciation and species-specific requirements of phytoplankton, remains largely unresolved. Siderophores are relevant within the pool of ... -
“Effect of inbreeding on egg size and clutch size in an insular house sparrow metapopulation in northern Norway”
(Master thesis, 2023)Innavlsdepresjon er en av de største truslene mot overlevelsen til små, isolerte bestander. For å få en fullstendig forståelse av innavlens innvirkning på populasjonens levedyktighet er det nødvendig å kvantifisere ... -
The Effect of Management on Effective Population Size in the Arctic Fox (Vulpes lagopus) Metapopulation in Scandinavia.
(Master thesis, 2017)Estimates of effective population size (Ne) may provide insight to patterns of changes in allele frequencies and heterozygosity in a population. Furthermore, by estimating Ne, one can predict future changes in genetic ... -
Effect of Manipulated Stress Levels of Adult Kittiwakes (Rissa tridactyla) on Offspring Immunocompetence
(Master thesis, 2013)Low food availability increase food stress and can cause a shift of energy expenditure to invest in self-survival rather than reproductive effort in breeding Black-legged kittiwakes (Rissa tridactyla). This affects early ... -
The effect of mild whole-body cold stress on isometric force control during hand grip and key pinch tasks
(Peer reviewed; Journal article, 2020)Prolonged exposure to cold can impair manual performance, which in turn can affect work task performance. We investigated whether mild whole-body cold stress would affect isometric force control during submaximal hand grip ... -
