Aromatic plants in nests of blue tits (Cyanistes caeruleus)
(Master thesis, 2024-11-20)Blue tits (Cyanistes caeruleus) build their nests out of moss and line them with insulating materials such as feathers, fur, and hair. In the southern areas of the species distribution range, blue tits often add aromatic ... -
Hvilke klimavariabler er viktig for variasjon i diversitet og komposisjon av floraen på fjelltopper i Nord-Norge?
(Master thesis, 2024-11-20)Denne studien undersøker hvordan diversitet og komposisjon av karplanter på fjelltopper i Nord-Norge påvirkes av dagens klimatiske situasjon. Lignende studier har blitt gjennomført tidligere, men gjerne på et mer globalt ... -
Hvilken effekt har klimaendringer hatt på økologiske samfunn i alpine områder?
(Master thesis, 2024-11-20)Hensikt: Økende global oppvarming kan skape store konsekvenser for det biologiske mangfoldet. Med økende temperaturer er det observert en økning av termofile arter, og/eller nedgang av kuldetolerante arter i alpine områder. ... -
Does pollinator-dependency in vascular plants affect the elevational range expansion of species in the northern Scandinavian mountains?
(Master thesis, 2024-11-20)Rising temperatures have led to the number of species increasing on mountain peaks across Europe. A greater increase in species richness leads to more competition for resources on the mountains which threatens local species. ... -
Effekter av klimaendringer på artskomposisjon av karplanter på fjelltopper i Nord-Norge
(Master thesis, 2024-11-20)Global oppvarming fører til omfattende endringer i strukturen og sammensetningen av plantesamfunn. Særlig utsatt er økosystemer som befinner seg på de kaldeste marginene på jorden, som fjelltopper. Planter i disse områdene ... -
Investigating shifts in epifaunal communities in Zostera marina meadows and Fucus serratus beds in the Norwegian Skagerrak
(Master thesis, 2024-06-03)Coastal ecosystems are under increasing pressure from climate change and other anthropogenic stressors, including along the coast of Norway. Seagrass meadows and macroalgal beds are two highly productive coastal ecosystems ... -
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 ... -
Histological analysis of intestine in Atlantic Halibut (Hippoglossus hippoglossus) larvae – looking for clues to explain larval mortality
(Master thesis, 2024-06-03)The value of the Atlantic halibut (Hippoglossus hippoglossus) has increased a lot over the last years, as well as the Atlantic halibut aquaculture industry. The aquaculture industry has always dealt with problems, and one ... -
Piscine orthoreovirus-1 (PRV-1) infection dynamics: Investigation through temporal profiling of factors affecting viral susceptibility, infectiousness, and persistence in Atlantic salmon
(Master thesis, 2024-02-15)In recent years, Norway has accounted for >50% of the global commercial production of Atlantic salmon. This growth in production has also resulted in an increased emergence of several viral diseases. Heart and skeletal ... -
Pacific white shrimp (Litopenaeus vannamei) cultured in recirculating aquaculture systems (RAS). Effects of density on growth, mortality, and welfare
(Master thesis, 2024-06-03)Aquaculture is a rapidly growing industry and one of the most vital pillars in addressing the increasing global demand for food. Different farming systems and strategies have been developed to achieve more modern and ... -
The effect of dissolved oxygen on feed intake, growth and nutrient utilization in Atlantic salmon (Salmo salar)
(Master thesis, 2024-06-03)Atlantic salmon (Salmo salar) is a species of significant economic importance in aquaculture. Optimal growth and nutrient utilization are critical for the efficient production of Atlantic salmon. However, especially during ... -
Varying back-calculated growth in Atlantic herring (Clupea harengus) along the Norwegian coast based on scales and otoliths
(Master thesis, 2024-06-03)Atlantic herring display a wide spatial distribution where its numerous populations encounter various environmental factors and selective forces, thus having different prerequisites for growth. This report aims to provide ... -
Using a greenhouse experiment to test the consistency in the chemical response of Pinus sylvestris and Pinus uncinata pollen to UV-B radiation
(Master thesis, 2024-06-17)Previous studies have suggested that the amount of UV-B absorbing compounds (UAC) found in pollen grains increases when the plants are exposed to UV-B radiation. If this response is consistent across and within populations, ... -
A rational approach for estimating antioxidant capacity: from dietary fish formulations to bioreactor water samples
(Master thesis, 2024-06-03)Concern about the harmful properties of synthetic antioxidants, such as butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), or ethoxyquin, in fish feed has led to the banning of ethoxyquin by the European Union ... -
A study of bee flight activity in relation to flowering in a fruit-growing region in western Norway
(Master thesis, 2024-04-03) -
Spatial and Temporal Variation in length-at-Age in Northeast Arctic haddock (Melanogrammus aeglefinus)
(Master thesis, 2024-06-03)Summary: The growth of fish is one of the most important factors in fisheries management. As fish grow, their lifestyles often change considerably including their food sources and the species that prey on them. Growth is ...
