Produced water components: uptake kinetics and effects on the metabolism of the Arctic copepod Calanus glacialis
(Master thesis, 2016)The oil exploration and search for new oil production fields is expanding further north and has reached the Arctic. Oil drilling activities release large amounts of produced water (PW) to the marine environment and sub-lethal ... -
Produced water from North Sea offshore oil platforms causes a suite of biological effects on developing lumpfish (Cyclopterus lumpus) eggs.
(Master thesis, 2020)This study investigated the impacts of several produced waters (PWs) from the North Sea on developing Cyclopterus lumpus larvae. Larvae were exposed for 96 hours early in development to 3 concentrations of 5 different PW ... -
Production and nutritional adaptation of the brine shrimpArtemia sp. as live food organism for larvae of marine cold water fish species
(Doctoral thesis, 2001)High nutritional value of Artemia sp. refers to high content of highly unsaturated fatty acids (n-3 HUFA) and in particular the content of DHA. In the enrichment experiments presented in this thesis new diets and one new ... -
Promoting bird conservation in wetland-associated landscapes: Factors influencing avian crop damage and farmers’ attitudes
(Peer reviewed; Journal article, 2022)Integrating agroecosystems as bird habitats are very important for long-term conservation planning because intensified agricultural land use has been a global threat to avifauna. To make agriculture compatible with ... -
Propionate induces intestinal oxidative stress via Sod2 propionylation in zebrafish
(Peer reviewed; Journal article, 2021)Propionate and propionyl-CoA accumulation have been associated with the development of mitochondrial dysfunction. In this study, we show that propionate induces intestinal damage in zebrafish when fed a high-fat diet (HFD). ... -
PROTAX-Sound: A probabilistic framework for automated animal sound identification
(Journal article; Peer reviewed, 2017)Autonomous audio recording is stimulating new field in bioacoustics, with a great promise for conducting cost-effective species surveys. One major current challenge is the lack of reliable classifiers capable of multi-species ... -
Proteininnhold og vekst for Saccharina latissima dyrket ved varierende tilførsel av nitrat og lys
(Master thesis, 2015)Det trengs en økning av matproduksjonen i verden, og en løsning er økning av akvakultur. For at en økning i akvakultur av fôrede arter skal være mulig og bærekraftig trengs det en ny kilde til proteiner som kan supplere ... -
Proteome and Growth Responses of the Key Species Calanus finmarchicus to future Ocean Acidification and Warming
(Master thesis, 2015)The zooplankton Calanus finmarchicus is a key species in the North Atlantic, by linking the primary production with upper trophic levels and by contributing to vertical export of carbon. Copepod eggs were cultured to a ... -
Proteomic study of low temperature responses in strawberry cultivars (Fragaria x ananassa Duchesne) that differ in cold tolerance
(Journal article; Peer reviewed, 2012)To gain insight into the molecular basis contributing to overwintering hardiness, a comprehensive proteomic analysis comparing crowns of Fragaria × ananassa (octoploid strawberry) cultivars that differ in freezing tolerance ... -
Protocol for stable germ-line mutagenesis facilitated by CRISPR/Cas9 RNP complex via peptide nanoparticle microinjection in Salmon lice (Lepeophtheirus salmonis)
(Master thesis, 2021)Aquaculture is a rising economical industry since its inception, that is positioned as sustainable and reliable food source for continuously expanding human population. Salmon farming produces nutrition rich in omega−3 and ... -
Provisioning tactics of great tits (Parus major) in response to long-term brood size manipulations differ across years
(Journal article; Peer reviewed, 2017)Parents provisioning their offspring can adopt different tactics to meet increases in offspring demand. In this study, we experimentally manipulated brood demand in free living great tits (Parus major) via brood size ... -
Proximity to high densities of pastoral settlements reduces grassland regrowth in a protected tropical savanna
(Journal article; Peer reviewed, 2021)Sedentarization of pastoralist communities is reshaping the structure and functioning of tropical savannas. Of particular concern is how permanent pastoral settlements change grassland vegetation inside “protected” areas. ... -
Public health implications of endocrine disrupting chemicals in drinking water and aquatic food resources in Nigeria: A state-of-the-science review
(Peer reviewed; Journal article, 2023)This state-of-the-science review is aimed at identifying the sources, occurrence, and concentrations of EDCs, including potential public health risks associated with drinking water and aquatic food resources from Nigerian ... -
Purification and characterization of an unusual DNA glycosylase in diatoms
(Master thesis, 2012)DNA damage may be caused by many different agents, including radiation, spontaneous mutations and chemical mutagens. If the damage is left unrepaired, it may result in mutations or cell death. All organisms contain repair ... -
Quality Characteristics of Sous-vide Cooked Atlantic Herring--Effect of Natural Plant Antioxidants and Frozen Storage
(Master thesis, 2020)Atlantic herring has a high nutritional value and is a good source of lipids with a high content of PUFAs (polyunsaturated fatty acids) in addition to protein, minerals (calcium, phosphorus, magnesium) and vitamins (A, D). ... -
Quality of Atlantic Cod Frozen in Cell Alive System, Air-Blast, and Cold Storage Freezers
(Journal article; Peer reviewed, 2016)Gutted Atlantic cod, packed in cartons, were frozen immediately after killing in a magnetic field (cell alive system). The results were compared with traditional air-blast freezing or by putting the cartons directly in a ... -
Quantifying fixed individual heterogeneity in demographic parameters: Performance of correlated random effects for Bernoulli variables
(Peer reviewed; Journal article, 2021)1. An increasing number of empirical studies aim to quantify individual variation in demographic parameters because these patterns are key for evolutionary and ecological processes. Advanced approaches to estimate individual ... -
