Male mate choice and selectivity in relation to female body size, in the seed beetle Callosobruchus maculatus
(Master thesis, 2019-06-21)Selectivity in mate choice and mating behaviour is a central element of sexual selection, and an important component of evolution in a number of species across the animal kingdom. Mate choice relates to how individuals ... -
Male mate choice and selectivity in relation to female mating status in the seed beetle Callosobruchus maculatus
(Master thesis, 2021-06-01)Sexual selection plays a role in evolution and often follows the pattern where males are fighting to mate, while females are choosy due to their higher gamete investment. Males can also be selective if they have high costs ... -
Mapping the amino acid composition of the peripheral membrane binding interface of PH domains
(Master thesis, 2021-11-24)Biological membranes are important in the organization of cells, and the main components of membranes are different kinds of lipids. Peripheral proteins are soluble and interact transiently and bind reversibly to lipids ... -
Metabolic properties of the hyperthermophilic sulfate reducing archaea of the genus Archaeoglobus in deep-sea hydrothermal vent systems
(Master thesis, 2019-06-21)Along the mid-ocean ridge system, super-heated fluids rich in metal sulfides expel out of the ocean floor, precipitating sulfides and forming black smoker chimneys. The precipitated sulfide forms the chimney wall and the ... -
Metagenomics-based discovery of novel carbohydrate degrading enzymes from deep-sea hydrothermal in situ enrichments; expression, purification and characterization
(Master thesis, 2021-06-01)Deep sea hydrothermal vents located along ocean ridges harbor microorganisms with unique adaptations. These extremophiles have adapted to high temperature and extreme conditions. Carbohydrate acting enzymes with thermostable ... -
Microparasites in selected populations of wild Atlantic salmon (Salmo salar) in Norway – Prevalence, density and diversity
(Master thesis, 2019-06-26)The aim of this study was to investigate the prevalence, density and diversity of microparasites in Atlantic salmon from selected populations in Norway including and to provide an assessment of the possible spreading of ... -
Microplastic in the Urban Environment - Concentrations and Sources in Streets and Sand Traps

Modelling the switch between bite-feeding and filter-feeding in planktivorous fishes
(Master thesis, 2019-12-10) -
Molekylær karakterisering og analyse av uttrykkingsmønsteret til T-cellemarkørene CD4-1 og CD8-alfa i berggylt (Labrus bergylta)
(Master thesis, 2021-06-01)Proteinene CD4-1 og CD8-alfa er essensielle ko-reseptorer på T-celler, og nyttige markører for å identifisere bestemte sub-populasjoner av celler i immunforsvaret. Målet med denne oppgaven var å karakterisere disse molekylene ... -
Nest predation, reproductive investment, and environmental variability in Atlantic puffin (Fratercula arctica)
(Master thesis, 2021-06-30)For many species of birds, nest predation is one of the leading causes of reproductive failure. This has been especially apparent in island nesting seabirds, which have experienced rapid declines due to the introduction ... -
Optimising cell wall disruption of microalgae biomass for release of nutrients and bioactive compounds for aquafeed and food applications
(Master thesis, 2019)Microalgae are photosynthetic organisms and primary producers of essential nutrients in the aquatic food chain. Although currently less exploited, microalgae culture can provide nutrients to cover the increasing demand for ... -
Otolith growth of herring (Clupea harengus) and sprat (Sprattus sprattus) in the Norwegian fjords
(Master thesis, 2022-06-01)Small pelagic fish play an important role in the ecosystem and are an important economical resource. The two most abundant pelagic fish in the Norwegian fjords are herring and sprat. It is documented that offshore sprat ... -
Paramoeba perurans and AGD in Norwegian aquaculture: effect of freshwater treatment against AGD on gill health in commercial production of Atlantic salmon (Salmo salar L.) and experimental testing of virulence of Paramoeba perurans
(Master thesis, 2021-06-11)Gill diseases are a major and increasing challenge with respect to fish health and welfare during the marine stage in Atlantic salmon farming. The causative agents for gill diseases are complex, and several pathogens are ... -
Personlighet og læring blant biologistudenter: En kvantitativ pilotstudie av dyp prosessering og åpenhet for erfaring blant førsteårsstudenter i biologi
(Master thesis, 2019-12)Studenter har ulike måter å tilnærme seg læring på, og dette kan avhenge av for eksempel personlighetstrekk eller hvilken hensikt man har med læringsprosessen. En person som er åpen for nye erfaringer vil gjerne ha en ... -
Perspectives on intended learning outcomes in the field course and their assessment
(Master thesis, 2020-03-31)This thesis examines the assessment practices of biology courses at the University level that feature a fieldwork component (field course). Seven professors who teach and administrate such courses were interviewed about ...
