(Master thesis, 2024-06-03) -
Factors affecting the degree of vertical stratification of fatty acids in grey seal blubber
(Peer reviewed; Journal article, 2019)The biochemistry of marine mammal blubber differs vertically from skin to muscle, which forms a challenge for using fatty acids (FAs) from differently sampled blubber as a proxy for dietary studies required for ecosystem-based ... -
Factors affecting the efficiency and selectivity of the Andaman Sea demersal sampling trawl
(Master thesis, 2011-12-05)The average catch per unit of swept area (CPUE) from bottom trawl surveys by research vessels are used as an index of abundance for the demersal fish resources of the Thai waters of the Andaman Sea. The surveys are carried ... -
Factors leading to variation of spawning time in the Barents Sea capelin (Mallotus villosus)
(Master thesis, 2015-11-20)Barents Sea capelin (Mallotus villosus) is a semalparous fish species, and the timing of spawning both in terms of age and season is variable. The present thesis explores potential factors leading to variation in timing ... -
Fangst av krill og torsk (Gadus morhua) ved bruk av lys; effekt av lyskildens egenskaper.
(Master thesis, 2018-06-26)Krillens adferd rundt lys er lite studert i felt, men er viktig med tanke på utviklingen innen teinefiske etter fisk (Torsk, Gadus morhua), da det brukes lys for å tiltrekke levende bytte og motivere fisken til å gå i ... -
Fast and Quantitative Phospholipidomic Analysis of SH-SY5Y Neuroblastoma Cell Cultures Using LC-MS/MS and 31P NMR
(Peer reviewed; Journal article, 2019)Global lipid analysis still lags behind proteomics with respect to the availability of databases, experimental protocols, and specialized software. Determining the lipidome of cellular model systems in common use is of ... -
Fast evolving 18S rRNA sequences from Solenogastres (Mollusca) resist standard PCR amplification and give new insights into mollusk substitution rate heterogeneity
(Peer reviewed; Journal article, 2010-03-09)Background: The 18S rRNA gene is one of the most important molecular markers, used in diverse applications such as molecular phylogenetic analyses and biodiversity screening. The Mollusca is the second largest phylum within ... -
Fast water currents reduce production performance of post-smolt Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2015-09-17)In the future, an increasing number of salmon farms may be located in areas with fast water current velocity due to limited availability of more sheltered locations. However, there is little information as to how fast ... -
Fauna associated with non-native Sargassum muticum (Fucales, Phaeophyceae) vary with thallus morphology and site type (sounds and bays)
(Journal article; Peer reviewed, 2021)The invasive brown alga Sargassum muticum was first recorded in Norway in 1988 and is presently common in the sublittoral fringe on the sheltered coast in South Norway. Here, results from a study on mesofauna associated ... -
Faunal Colonization of Submarine Mine Tailings: An Intertidal Experiment to Investigate the Infuence of Sediment Organic Carbon Content
(Master thesis, 2014-06-02)Current financial estimates of mineral mining in Norway are approximately 12 billion NOK per year. Most of the industry is located close to the coastline and the inert waste produced ( tailings', granulometrically similar ... -
Faunal trophic structure at hydrothermal vents on the southern Mohn's Ridge, Arctic Ocean
(Peer reviewed; Journal article, 2013)We explore the trophic ecology of heterotrophic fauna associated with a high temperature (HT) vent, 2 low temperature vents, a ‘near-HT vent’ habitat and a non-vent site situated at upper bathyal depths on the southern ... -
Fe(II) stability in coastal seawater during experiments in Patagonia, Svalbard, and Gran Canaria
(Journal article; Peer reviewed, 2020-03)The speciation of dissolved iron (DFe) in the ocean is widely assumed to consist almost exclusively of Fe(III)-ligand complexes. Yet in most aqueous environments a poorly defined fraction of DFe also exists as Fe(II), the ... -
Feeding behavior and bioenergetic balance of the great scallop (Pecten maximus) and the blue mussel (Mytilus edulis) in a low seston environment and relevance to suspended shellfish aquaculture.
(Doctoral thesis, 2009-11-20)The length of the rugged Norwegian coastal line including all islands exceeds the circumference of the earth, and the coastal zone contains many sheltered areas that are potentially suitable for bivalve farming. However, ... -
Feeding ecology of Benthosema glaciale across the North Atlantic
(Journal article; Peer reviewed, 2023-02-16)The glacier lanternfish Benthosema glaciale is a key myctophid with a wide distribution in the northern Atlantic. It is a species that has a strong vertical migration capacity and have the potential to move between the ... -
Feeding ecology of Coryphaenoides rupestris from the Mid-Atlantic Ridge
(Peer reviewed; Journal article, 2010-05-03)The Macrourid fish roundnose grenadier, Coryphaenoides rupestris, is one of the most common benthopelagic fishes on the northern mid-Atlantic Ridge. The ecology of the species is comparatively well studied in continental ... -
