Effects of temperature and food availability on larval cod survival: A model for behaviour in vertical gradients
(Peer reviewed; Journal article, 2015-06-08)Recruitment success in living marine resources is variable due to high survival variability of early life stages. Improving our understanding of how environmental and ecological factors mechanistically interact and influence ... -
Effects of temperature and natural disturbance on growth, reproduction, and population density in the alpine annual hemiparasite euphrasia frigida
(Peer reviewed; Journal article, 1999)The effects of temperature and "natural disturbance" on growth, seed production, and population density in the facultative hemiparasitic annual Euphrasia frigida (Scrophulariaceae) were examined in the middle alpine zone ... -
Effects of temperature on tissue-diet isotopic spacing of nitrogen and carbon in otolith organic matter
(Peer reviewed; Journal article, 2019)Reconstruction of the trophic position of a fish can be performed by analysing stable nitrogen and carbon isotopes in otolith protein. However, ambient temperature may affect the tissue–diet isotopic spacing of stable ... -
Effects of temperature regimes on proportion of early maturation and the activation of the BPG axis in male Atlantic salmon (salmo salar L.) postsmolts
(Master thesis, 2023-06-02)Early maturation of Atlantic salmon (salmo salar L.) male postsmolts is a growing concern for the Norwegian aquaculture industry due to an increasing occurrence in intensive rearing facilities, negatively impacting growth, ... -
The effects of the chemotherapeutants hydrogen peroxide, deltamethrin and azamethiphos on non-target crustaceans
(Doctoral thesis, 2021-09-16)I present new knowledge on the toxicity of three major bath treatment chemotherapeutants used in Norway. Previously, regarding the toxicity studies of hydrogen peroxide (H2O2) alone, a total of twelve non-target crustaceans ... -
Effects of the emerging marine aquafeed mycotoxins beauvericin (BEA) and enniatin B (ENNB) in Atlantic Salmon (Salmo salar) – Implications on cellular pathways and functions, and tissue responses
(Doctoral thesis, 2023-06-14)Plantebaserte fôringredienser er en kilde til mykotoksinene enniatin B (ENNB) og beauvericin (BEA) for oppdrettslaks (Salmo salar). Dette har skapt bekymring for fiskehelse og fôrsikkerhet, siden disse mykotoksinene foreløpig ... -
Effects of the guide field on electron distribution functions in the diffusion region of asymmetric reconnection
(Peer reviewed; Journal article, 2019)Crescent electron distribution functions in the electron diffusion region in asymmetric reconnection with a guide field (strength less than 50% of the upstream magnetic field) are investigated by theory and fully kinetic ... -
Effects of thermally-dependent rock parameters on fracture reactivation
(Master thesis, 2019-07-09)The slip tendency is an important tool to measure fracture reactivation in thecontext of subsurface engineering applications. In this thesis, the effects of thermally-dependent rock parameters such as Young’s modulus on ... -

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 ... -
Effects of wave-induced processes in a coupled wave-ocean model on particle transport simulations
(Journal article; Peer reviewed, 2021)This study investigates the effects of wind–wave processes in a coupled wave–ocean circulation model on Lagrangian transport simulations. Drifters deployed in the southern North Sea from May to June 2015 are used. The ... -
Effects of within-lake variability of fossil assemblages on quantitative chironomid-inferred temperature reconstruction
(Peer reviewed; Journal article, 2003)We studied the effects of within-lake variation of subfossil chironomid assemblages on chironomid-inferred temperatures in five lakes in southern Norway. In each lake six replicate surface-sediment samples in the deepest ... -
Effects on individual level behaviour in mackerel (Scomber scombrus) of sub-lethal capture related stressors: Crowding and hypoxia
(Peer reviewed; Journal article, 2019-03-13)Stress to fish during harvest in wild capture fisheries is known to negatively influence subsequent survival in catches that are released. Therefore, if fisheries are to be conducted sustainably, there is a need to promote ... -
Effects on schooling function in mackerel of sub-lethal capture related stressors: Crowding and hypoxia
(Peer reviewed; Journal article, 2017-12-28)The selectivity of fishing gears with respect to fish species and size is important, both for fisheries management and fishing operations. Purse seining is an efficient, environmentally friendly fish capture methodology ... -
Effekt av ferskvassbehandling på gjeller hjå laks (Salmo salar L.) med amøbegjellesjukdom (AGD): gjellepatologi, prevalens og tettleik av Paramoeba perurans
(Master thesis, 2020-06-23)Eit av dei største problema ein opplever i sjøfasen hjå oppdrettslaks er dårleg gjellehelse. Det har eit komplekst årsakstilhøve og er ofte assosiert med eit breitt spekter av patogen. Eit av patogena som kan infisere ... -
