The Infection Cycle of Marteilia pararefringens sp. nov. in the blue mussel, Mytilus edulis L.
(Master thesis, 2019-06-18)In 2016 the first case of marteiliosis in Norway was reported by the Institute of Marine Research. The discovery occurred in Agapollen, Bømlo, a previously active oyster pond. The parasite Marteilia pararefringens sp. nov. ... -
The influence of re-establishing Eurasian otter (Lutra lutra) on the activity of invasive American mink (Neovison vison) on the southwest coast of Norway
(Master thesis, 2023-06-02)Invasive species are one of the most impactful sources of biodiversity loss worldwide. Generalist predators may be especially damaging, as they can reduce survival and fecundity in native species and can compete with native ... -
The neighborhood matters: warming and novel competitors alter flower production of alpine plants
(Master thesis, 2022-06-01)Sexual reproduction, and the genetic variation it entails, could prove vital for plants’ ability to persist under a changing climate. Climate warming is causing species to shift their ranges to higher elevations and ... -
The Potential of Small Fish to Alleviate Micronutrient Deficiencies. A Case Study of Ghana.
(Master thesis, 2021-08-02)Abstract Micronutrient deficiency also referred to as “hidden hunger” is one of the prevalent forms of malnutrition with about 340 million children deficient in essential vitamins and minerals globally (FAO, 2020). Fish ... -

The role of bioluminescent prey in the diet of two hatchetfish species and four lanternfish species in the North Atlantic Ocean in relation to eye-size
(Master thesis, 2023-06-16)The mesopelagic zone, often referred to as “the twilight zone” can be defined as the area of the ocean at 200-1000 m depth. Here, light levels vary greatly and provides a varying visual scene. At shallow depths, down-welling ... -
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 ... -
The role of marine nutrients in 2,3,7,8-tetrachlorodibenzo-p-dioxin toxicity in vitro and in vivo
(Master thesis, 2022-06-01)2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is the most potent dioxin congener and is associated with several adverse health effects. As a result of its high lipophilicity and slow degradation the compound easily accumulates ... -
The role of spatial dependency in niche shifts of invasive species
(Master thesis, 2023-09-01)Invasive species are an ongoing threat to nature and human interests. Species distribution models are used to predict the current and potential distribution of invasive species, but doing so has proved difficult. One ... -
The small-scale fisheries of Timor-Leste and the impacts of the COVID-19 pandemic
(Master thesis, 2021-08-02)Small-scale fisheries (SSFs) of developing countries are an important yet neglected part of the world’s capture fisheries. The general lack of fisheries dependent and independent data makes it difficult to predict the ... -
Tilrettelegging for elever med lese- og skrivevansker under praktisk arbeid i biologi. En kvalitativ studie av læreres kunnskaper om og tilrettelegging for elever med lese- og skrivevansker under praktisk arbeid i biologi i videregående skole
(Master thesis, 2023-11-20)Biologifaget inneholder abstrakte og komplekse prosesser og teorier som kan føre til vanskeligheter med å tilegne seg kunnskapen særlig for dem som har lese- og skrivevansker. Praktisk arbeid kan være spesielt viktig fordi ... -
Tissue tropism and optimization and evaluation of diagnostics test for the detection of Pilchard orthomyxovirus (POMV) in Atlantic salmon (Salmo salar)
(Master thesis, 2020-06-12)Since 2012, pilchard orthomyxovirus (POMV) has been of major concern to the Tasmanian salmonid industry. The virus was first discovered in pilchards, and is, so far, only shown to be highly infectious to Atlantic salmon ... -
Tolerance limits to fluctuating water currents in Atlantic salmon (Salmo salar): A novel method to simulate the impact of ocean waves on salmon welfare in the laboratory
(Master thesis, 2023-06-02)The Norwegian aquaculture industry aims to expand the production of Atlantic salmon (Salmo salar) to offshore locations where the fish will be experiencing more extreme weather conditions compared to traditional sheltered ... -
Towards a challenge model for the tapeworm Eubothrium crassum - incubation of cestode eggs and maintenance of a marine intermediate host, Acartia tonsa
(Master thesis, 2022-06-01)Bendelormen Eubothrium crassum Bloch (Cestoda: Bothriocephalidea) er en parasitt som forekommer hovedsakelig hos laksefisker i både ferskvann og sjøvann. Den er et økende problem i norsk oppdrettslaks (Salmo salar Linnaeus) ... -
Tracking the time course of reproductive events in the Northeast Arctic haddock (Melanogrammus aeglefinus)
(Master thesis, 2021-06-15)An important objective of fisheries management is to ensure harvest rates that allows the population to maintain its reproductive potential over time. Reproductive biology is thus of key importance when managing a fish ... -
Trichlorfon, a salmon lice pesticide, and the effect on metabolism and inflammation in Atlantic salmon (Salmo salar, L.)
(Master thesis, 2020-06-26)Since the beginning of the salmon farming industry in Norway, the substantial fish health and welfare and economic costs caused by the parasitic salmon lice (Lepeophtheirus salmonis) has increased in tandem with the expanding ... -
Trophic structure of mesopelagic species in the Northeast Atlantic Ocean based on stable isotopes of carbon and nitrogen
(Master thesis, 2021-09-03)The mesopelagic zone is one of the largest, yet among the least explored habitats of the planet. Possible estimates of fish living in this zone range from around 1 to 15 billon tones of biomass which is 10 to 15 times that ...
