Effects of reduced diameter of bag cultures on content of essential fatty acids and cell density in a continuous algal production system
(Peer reviewed; Journal article, 2011-02-16)Cell density and fatty acid (FA) content of Pavlova lutheri and Chaetoceros muelleri were analysed in a continuous algal production system (250-L bags) with reduced diameter. The cell density and FA content and composition ... -
Effects of reforestation and intensified land use on vascular plant species richness in traditionally managed hay meadows
(Peer reviewed; Journal article, 2003)In this study of 130 sites with different management we investigated whether vascular plant species richness is significantly reduced when traditionally managed hay meadows are abandoned and reforested. We also compared ... -
Effects of replacing fish meal with plant protein in diets for Atlantic cod (Gadus morhua L.)
(Doctoral thesis, 2009-09-18)In Northern Europe, interest in farming Atlantic cod Gadus morhua L. has increased steadily over the past decade stimulated by the decline in landings from fisheries, and the more predictable supply by hatchery reared ... -
Effects of salinity on hydrate stability and implications for storage of CO2 in natural gas hydrate reservoirs
(Peer reviewed; Journal article, 2009-02)The win-win situation of CO2 storage in natural gas hydrate reservoirs is attractive for several reasons in addition to the associated natural gas production. Since both pure CO2 and pure methane form structure I hydrate ... -
Effects of sample handling and cultivation bias on the specificity of bacterial communities in keratose marine sponges
(Peer reviewed; Journal article, 2014-11-18)Complex and distinct bacterial communities inhabit marine sponges and are believed to be essential to host survival, but our present-day inability to domesticate sponge symbionts in the laboratory hinders our access to the ... -
Effects of sea-ice and biogeochemical processes and storms on under-ice water fCO2 during the winter-spring transition in the high Arctic Ocean: Implications for sea-air CO2 fluxes
(Peer reviewed; Journal article, 2017-07)We performed measurements of carbon dioxide fugacity (fCO2) in the surface water under Arctic sea ice from January to June 2015 during the Norwegian young sea ICE (N-ICE2015) expedition. Over this period, the ship drifted ... -
Effects of seismic shooting on the lesser sandeel (Ammodytes marinus Raitt) - a field study with grab sampling and in situ video observations
(Master thesis, 2004)Seismic shooting with airguns has been conducted continuously in the North Sea for about 40 years. In the past two decades there has been conflicts of interest between Norwegian industrial trawlers fishing for sandeel and ... -
The effects of selective harvest on Japanese Spanish mackerel (Scomberomorus niphonius) phenotypic evolution
(Journal article; Peer reviewed, 2022)Japanese Spanish mackerel (Scomberomorus niphonius) is an important fish species in the China Seas with wide distribution, extensive migration, and high economic value. This species has been yielding high fisheries production ... -
The effects of selenium on methylmercury toxicity in zebrafish
(Doctoral thesis, 2014-10-31)Methylmercury (MeHg) is a potent neurotoxicant that remains a global concern. Selenium (Se) is an important micronutrient which is able to decrease MeHg toxicity, although the underlying mechanisms for this protection ... -
Effects of short term fasting on mRNA expression of ghrelin and the peptide transporters PepT1 and 2 in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2021)Food intake is a vital process that supplies necessary energy and essential nutrients to the body. Information regarding luminal composition in the gastrointestinal tract (GIT) collected through mechanical and nutrient ... -
Effects of short-term starvation periods on flesh quality in Arctic charr (Salvelinus alpinus) in different seasons
(Journal article; Peer reviewed, 2020)Possible effects of short‐term starvation on flesh quality in Arctic charr were studied in spring (March) and summer (August). Groups of juvenile Arctic charr (mean weight March 536 g ± 24; August 461 g ± 15 SEM) were ... -
Effects of simulated environmental changes on growth and growth form in a late snowbed population of pohlia wahlenbergii (Web. et Mohr) Andr
(Peer reviewed; Journal article, 2003)In a factorial field experiment we increased the temperature (OpenTop Chambers) and nutrients (nitrogen, phosphorus, and potassium[NPK]) to simulate predicted future climate changes and studiedthe growth response of the ... -
Effects of simulated natural variability on Arctic temperature
(Journal article, 2005-09-23)A five-member ensemble with a coupled atmospheresea ice-ocean model is used to examine the effects of natural variability on climate projections for the Arctic. The individual ensemble members are initialized from a 300 ... -
Effects of soil organic matter properties and microbial community composition on enzyme activities in cryoturbated arctic soils
(Peer reviewed; Journal article, 2014-04-04)Enzyme-mediated decomposition of soil organic matter (SOM) is controlled, amongst other factors, by organic matter properties and by the microbial decomposer community present. Since microbial community composition and SOM ... -
Effects of solar irradiance forcing on the ocean circulation and sea-ice in the North Atlantic in an isopycnic coordinate ocean general circulation model
(Peer reviewed; Journal article, 2004)The sensitivity of the ocean circulation to changes in solar irradiance is examined using an isopycnic coordinate, global ocean general circulation model (OGCM) coupled to a thermodynamic/dynamic sea-ice model. In the ... -

(Tellus;56A(2), Journal article, 2004-03)The sensitivity of the ocean circulation to changes in solar irradiance is examined using an isopycnic coordinate, global ocean general circulation model (OGCM) coupled to a thermodynamic/dynamic sea-ice model. In the ... -
The effects of spatial and temporal variations in spawning on offspring survival in Northeast Arctic cod
(Journal article; Peer reviewed, 2024)Climate change and harvesting result in temporal and spatial changes and variability in spawning, and thus in offspring ambient drift conditions. As a result, variable survival of offspring and thereby in recruitment are ... -
Effects of storage on product quality of bivalves (oysters, scallops, and clams)
