Establishing fin whale fibroblast culture conditions for toxicological studies
(Master thesis, 2022-10-03)Several marine mammal species have been hunted to near extinction by humans. As such, many of these species are vulnerable to population reductions due to changing climate, destruction of habitats, and environmental ... -
Diet variability in black-legged kittiwakes (Rissa tridactyla) in Kongsfjorden in relation to ongoing environmental changes
(Master thesis, 2022-11-21)The Atlantification of the European Arctic is defined as Atlantic water masses increasing their influence further North. This process, which is induced by climate warming, leads to changes in the physical and biological ... -

Effect-directed toxicity assessment of sediments from Bergen harbour (Norway) using luciferase reporter gene and cell-based bioassays
(Master thesis, 2022-10-01)Bergen harbour has been a historically polluted area in line with the harbours of many other major coastal cities in Norway and other countries around the world. With pollutants accumulating to toxic levels in organisms ... -
Pollination, wild bee communities and seed development in apple orchards of Sogn and Hardanger in Western Norway
(Master thesis, 2022-09-06)Human progression has led to and is still creating massive land use changes. This is the main driver of biodiversity loss, and we are currently living in the sixth mass extinction. Increased human populations need increased ... -
Spawning season fidelity in spring and autumn spawning Atlantic herring, Clupea harengus. - A comparative study of genomic and phenotypic separation methods
(Master thesis, 2019-06-14)Atlantic herring have a complex population structure and show a wide range of life history strategies, including spawning times and locations. Time of spawning is a key characteristic for population separation. Spawning ... -
The role of crawling predators in the decline and distribution of blue mussels in Norwegian coastal waters
(Master thesis, 2022-08-22)Blue mussels (Mytilus spp.) are declining in coastal areas around the world. In Norway, they thrive on floating structures, while on rocky shores they have widely disappeared. Proposed and elsewhere reliable drivers such ... -
Characterization of the pregnane X receptor (PXR) from European hake (Merluccius merluccius): cloning, ligand activation, and bioinformatical analyses
(Master thesis, 2022-09-08)As a response to adverse environmental conditions, organisms have throughout evolution generated a collection of gene families and pathways providing protection and repair of damage caused by physical, chemical, and ... -
Valorisation of waste streams from recirculating aquaculture systems by photoautotrophic microalgae
(Master thesis, 2022-09-11)The low water consumption in Recirculating Aquaculture Systems (RAS) can result in relatively high concentrations of polluting nutrients in effluent waste streams (WSs) compared to traditional Flow-through systems (FTS). ... -
Element composition of particulate matter in the North-West Barents Sea
(Master thesis, 2022-08-10)At the dawn of the 21st century, the Arctic Ocean ecosystem is at great risk due to rapid climatic change. The ice edge retreat observed in the Barents Sea and other sub-Arctic areas is so substantial that has led researchers ... -
The effects of water temperature and photoperiod: Investigating the cause of early activation of the BPG axis in male Atlantic salmon (Salmo salar) during the freshwater stages of development
(Master thesis, 2022-05-25)Early sexual maturation of Atlantic salmon (Salmo salar) post-smolts has been a major issue over the years and has recently become a prevalent issue in land-based production systems like the recirculating aquaculture systems ... -
Biologilærarar sine kunnskapar om arbeidsminnet
(Master thesis, 2022-06-01)Arbeidsminnet er ein funksjon i hjernen for å mentalt manipulere informasjon. Arbeidsminnet har avgrensa kapasitet og varigheit, noko som er sentralt i undervisningssamanheng fordi det påverkar elevar sine evner til å ... -
A comparison of the spatial ecology, trophic ecology, and hypoxia tolerance of Velvet belly lanternshark (Etmopterus spinax) and Blackmouth catshark (Galeus melastomus) in Norwegian fjords.
(Master thesis, 2022-06-01)Climate change and ocean warming are major drivers of deoxygenation in the ocean, and the effects of oxygen loss are more pronounced in fjords due to the basic fjord topography. Velvet belly lanternshark (Etmopterus spinax) ... -
Towards a challenge model for the tapeworm Eubothrium crassum - incubation of cestode eggs and maintenance of a marine intermediate host, Acartia tonsa
