Sår og sårheling hos atlantisk laks (Salmo salar L.) i RAS med sjøvannstilsetning og i tradisjonelle sjømerder
(Master thesis, 2020-12-12)Produksjon av postsmolt atlantisk laks (Salmo salar) i resirkulerende akvakultursystemer (RAS) med sjøvannstilsetning er tatt i bruk for å forkorte produksjonstiden i sjø. Dette er som følge av store utfordringer knyttet ... -
Does Brownification and Iron Affect Microbial Communities and Mixotrophic Activities? Experiences From a Mesocosm Experiment
(Master thesis, 2020-11-13)In one millilitre of seawater there is on average approximately a million microbial cells, and these are largely responsible for nearly half of all primary production on Earth. Mixotrophic microorganisms are ubiquitous in ... -
Er BIO 101 studentene anvendelsesorienterte? En kvantitativ studie om biologistudentenes læringsstrategier basert på Vermunts læringsmønster
(Master thesis, 2020-11-11)Bakgrunn: Denne biologididaktiske mastergraden tar for seg Vermunts lærings- mønstre (ILS ), som er bygget på SAL og SRL tradisjonen. Basert på dette fant Vermunt (1996) fire læringsstrategier (læringsorienteringer) som ... -
Systematic revision of the genus Jorunna (Nudibranchia: Discodorididae) in Europe with a focus on the J. tomentosa species complex
(Master thesis, 2020-09-01)Jorunna is a genus of Nudibranchia in the family Discodorididae, currently comprising 21 recognized valid species with a worldwide coastal distribution in the four main biogeographical regions Eastern and Western Atlantic, ... -
Infection dynamics of marine Eubothrium sp. (Cestoda) in farmed Atlantic salmon
(Master thesis, 2019-06-21)Infections with marine tapeworms have been reported as an increasing problem in aquaculture of Atlantic salmon (Salmo salar L.) in Norway over the last few years. These are caused by the cestode Eubothrium sp. Little is ... -
Effect of sex ratio variation on mating behaviour in a parasite, the salmon louse (Lepeophtheirus salmonis)
(Master thesis, 2020-09-01)In sexual organisms, females produce large gametes and their reproductive success is generally more limited by resources compared to males that produce many small gametes and are more limited by the number of mates. Because ... -
Can environmental toxins increase parasite fitness? Ecotoxicological studies on the effects of microcystin on the host-parasite dynamics of Schistocephalus solidus
(Master thesis, 2020-08-21)Background: Eutrophication of aquatic biomes and exacerbated climate change effects are expected to result in a global increase in harmful cyanobacterial blooms. Cyanotoxins are detrimental to animal health, but how they ... -
How will thawing permafrost affect the microbial abundance and diversity in the Arctic?
(Master thesis, 2020-07-09)Permafrost, permanently frozen soil, constitutes a major portion of the Earth’s terrestrial cryosphere and represents a unique niche for cold-adapted microorganisms. As the global temperature increases, it is still unknown ... -
Avfallsvann som et alternativt dyrkingsmedium for mikroalger med et høyt innhold av EPA og DHA
(Master thesis, 2020-07-02)Mikroalger har mulighet til å danne flere ulike komponenter av kommersiell verdi. Av spesielt stor interesse er deres innhold av de flerumettede fettsyrene eikosapentaensyre (EPA) og dokosaheksaensyre (DHA). Disse fettsyrene ... -
