Temperature-dependent development of embryonic, planktonic, and parasitic stages of the sea lice Caligus elongatus
(Master thesis, 2021-09-11) -
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 ... -
Effect of different arachidonic acid levels in broodstock diet on egg quality of ballan wrasse (Labrus bergylta)
(Master thesis, 2021-07-31)The production of ballan wrasse (Labrus bergylta) is growing and is becoming a focus area for the aquaculture industry. As a result of rising louse numbers and problems with resistance, biological methods such as cleaner ... -
Ecological Consequences of Ash Dieback in Western Norway
(Master thesis, 2021-06-30) -
A Field Study on the Effects of Norwegian Aquaculture Farms on the Intertidal Rocky Shore Community
(Master thesis, 2021-09-13)The aquaculture industry has more than doubled since the early 2000s, and the growth is not predicted to stagnate any time soon. Norwegian salmonid aquaculture cages are usually open where waste is flushed from the cage ... -
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 ... -
USING LIGAND-ACTIVATED RECEPTORS FROM ATLANIC COD (Gadus morhua) AND ZEBRAFISH (Danio rerio) TO ASSESS BIOLOGICAL EFFECTS OF PHARMACEUTICALS IN WASTEWATER IN BERGEN, NORWAY
(Master thesis, 2021-09-01)Pharmaceuticals and personal care products are continuously released into the marine environment through wastewater. Understanding the possible biological implications of pharmaceuticals specifically may be particularly ... -
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 ... -
Effects of vgll3 on maturation and its interaction with salinity in Atlantic salmon (Salmo salar, L)
(Master thesis, 2021-06-17)New emerging strategies in the production of Atlantic salmon (Salmo salar), for instance post-smolt and big smolt in land-based facilities experience maturation. High production rates, such as 24 hours photoperiods and ... -
Investigating the genetic origin of three Fucus morphotypes using microsatellite analysis
(Master thesis, 2021-06-30) -
Tegning som læringsstrategi blant biologistudenter: En kvantitativ pilotstudie av studenters syn på og bruk av tegning som læringsstrategi i biologi
(Master thesis, 2021-08-01)Tegning som læringsstrategi assosieres med langsiktig læring, og kan bidra til økt kritisk tenking, forståelse, engasjement og motivasjon. Visualisering er en sentral del av naturvitenskapelige disipliner. Tegning anerkjennes ... -
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 ... -
Comparing density of lumpfish (Cyclopterus lumpus) used in aquaculture to different welfare indicators
(Master thesis, 2021-05-31)Farmed lumpfish are commonly used as cleaner fish in the salmonid aquaculture industry, but a knowledge gap exists with regards to their density. Filling this knowledge gap is of importance, as the lumpfish have no swim ... -
A pilot study of lumpfish (Cyclopterus lumpus) skin health, reared with three different treatments in land-based facilities and commercial net-pens
(Master thesis, 2021-06-01)Biological delousing by the means of deploying cleanerfish is one of the methods applied in Atlantic salmon aquaculture to combat the sea lice (lepeophtheirus salmonis) infestation problem. The method is based on the natural ... -
Knagger og krydder - En kvalitativ intervjustudie av biologilæreres syn på evolusjon som sammenbindende faktor i biologiundervisningen
(Master thesis, 2021-05-31)Evolusjonsteorien regnes som en av de viktigste teoriene innen naturvitenskap, og er et overordnet rammeverk for alt innen biologi. I denne kvalitative studien ble seks biologilærere på videregående skole intervjuet om ... -
Læreboka si rolle i evolusjonsundervisninga
(Master thesis, 2021-05-31)Evolusjonsteorien er den store samlande ideen i biologivitskapen, og det er derfor viktig at befolkninga generelt har kunnskap om han. Skulen er den staden der det er størst potensiale for at opplysning om denne sentrale ... -
A comparison of egg investment in lesser black-backed gulls (Larus fuscus) from urban and non-urban colonies
(Master thesis, 2021-06-01)While the increasing worldwide urbanization generally has negative effects on biodiversity, some animals, like roof nesting gulls, are able to take advantage of these areas and have generated large populations in a number ...
