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 Long-Term Changes in Eelgrass Meadows Using Aerial Photography
(Master thesis, 2023-06-02) -
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 ... -

Microbial endocrinology and fish pathogenic bacteria
(Master thesis, 2024-06-03)Yersiniosis caused by Yersinia ruckeri and pasteurellosis caused by “Pasteurella atlantica gv. salmonicida” are bacterial diseases presenting substantial welfare challenges for Atlantic salmon in Norway. In recent years, ... -
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 subsurface water in the South Pacific Ocean
(Master thesis, 2023-07-01)Microplastic (MP) in the world’s oceans is a global concern. Studies on MP are frequently published, but there is limited information on MP in the South Pacific Ocean. Here, a seawater filtration unit collected MPs down ... -
Microplastic in the Urban Environment - Concentrations and Sources in Streets and Sand Traps
(Master thesis, 2020-12-01) -
Miljøoverlevelse hos Spironucleus salmonicida - parasitten som forårsaker systemisk spironukleose hos oppdrettslaks
(Master thesis, 2024-06-03)Spironucleus salmonicida er en alvorlig trussel mot oppdrettsnæringen, spesielt for atlantisk laks i Nord-Norge. Utbrudd av systemisk spironukleose forårsaket av denne encellede flagellaten har ført til betydelige økonomiske ... -
Modelling the Distribution of Norwegian Coastal Cod (Gadus morhua)
(Master thesis, 2023-06-02)Knowledge about a species' distribution, and the factors driving the distribution, is important in both fishery management and conservation. It can help explain distributional shifts and variations in abundance as a response ... -
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 ... -
Morphometric Relationships as Indicators of Sexual Maturation in Atlantic Salmon (Salmo salar)
(Master thesis, 2023-09-01)This study aimed to identify morphometric relationships in fish that could serve as indicators for status on sexual maturation in Atlantic salmon (Salmo salar). To achieve this, 250 salmon were netted out and individually ... -
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 ... -
Network Analysis of Salmon Lice Infestations and Connectivity Between Farms: Exploring Cluster Isolation in Norwegian Salmon Farming
(Master thesis, 2024-06-26)Salmon lice (Lepeophtheirus salmonis) are a major constraint to the sustainable growth of the Norwegian salmon farming industry. Salmon farming in open net pens leads to a proliferation and transmission of salmon lice which ...
