Effects of fish farm activities on the sponge Weberella bursa, and its associated microbiota
(Journal article; Peer reviewed, 2021)Sustained growth of world-wide sea farming and the search of optimal growing conditions have driven several countries, including Norway, to establish new finfish sites in more exposed, high current locations. Characterized ... -
Effects of formaldehyde and ethanol preservation on body and otoliths of Maurolicus muelleri and Benthosema glaciale
(Peer reviewed; Journal article, 1998)First of its kind, this study examines effects of preservatives on otoliths as well as on fish size and weight. Effects of 200 days of preservation in 4 % seawater formaldehyde solution and 80 % ethanol were investigated ... -
Effects of gas supersaturation on migrating Atlantic salmon smolt (Salmo salar) in Evangervatnet
(Master thesis, 2016-11-21)Total dissolved gas supersaturation (TDGS) downstream of power plants may cause harmful effects on the fauna in many rivers. The harmful effects of TDGS are known as gas bubble disease (GBD). TDGS has been proposed as one ... -
Effects of genetic complexity and time resolution in an individual-based model of mesopelagic fish with hunger and fear
(Master thesis, 2014-06-02)Many studies have shown that emotion systems are in use to direct behavior, which has also been utilized in a recent mathematical model. To investigate the general validity on the results from this model for vertical ... -
Effects of geography and species variation on selenium and mercury molar ratios in Northeast Atlantic marine fish communities
(Peer reviewed; Journal article, 2019-11-01)Methylmercury (MeHg) is a potent neurotoxin that bioaccumulates in seafood. Co-occurrence of selenium (Se) may affect the bioavailability and toxicity of MeHg in organisms. Here we report the concentrations of total mercury ... -
Effects of geophysical parameters on the seismic expression of the Maghlaq Fault, Malta: insights from outcrop-based 2D seismic modeling
(Master thesis, 2020-06-25)Faults are heterogenous zones comprising highly complex geometries, which can be studied in detail from field outcrops. The internal complexity of a fault zone is however difficult to interpret from seismic images, due to ... -
Effects of habitat enrichment and food availability on the foraging behaviour of juvenile Atlantic Cod (Gadus morhua L)
(Peer reviewed; Journal article, 2011-04-13)The environment can play an important role in shaping how an animal behaves, and how well the animal performs in a particular environment can be influenced by early experiences. The tradition of releasing captive-reared ... -
The effects of leptin and ghrelin on voluntary feed intake and appetite in Atlantic salmon Salmo salar
(Master thesis, 2013-10-01)Salmon farming has expanded dramatically in recent years, increasing the demand for both traditional feed ingredients and alternative proteins and oils. Developing new feed requires a deep understanding of appetite, feed ... -
Effects of magmatic intrusions on temperature history and diagenesis in sedimentary basins – and the impact on petroleum systems
(Doctoral thesis, 2020-04-23)For many volcanic basins, the thermal effect of igneous intrusions is decisive for their petroleum potential because such thermal impact may lead to maturation of organic material in areas that otherwise would remain ... -
Effects of Management on Heathland Vegetation in Western Norway
(Doctoral thesis, 2009-03-31)Aims: This synthesis of studies examines the effects of anthropogenic disturbance regimes; the traditional management practices of livestock grazing and prescribed burning, on vegetation and seed banks in coastal heathlands ... -
Effects of methane hydrates on two-phase relative permeability in sandstone: Numerical simulation of laboratory experiments
(Journal article; Peer reviewed, 2022)To identify the challenges and limitations in measuring and modelling gas relative permeability in hydrate bearing sandstone, we simulate a series of experiments. Experimental and numerical results are used to examine the ... -
Effects of motion correction, sampling rate and parametric modelling in dynamic contrast enhanced MRI of the temporomandibular joint in children affected with juvenile idiopathic arthritis
(Journal article; Peer reviewed, 2021)The temporomandibular joint (TMJ) is typically involved in 45–87% of children with Juvenile Idiopathic Arthritis (JIA). Accurate diagnosis of JIA is difficult as various clinical tests, including MRI, disagree. The purpose ... -
Effects of Multi-Shell Free Water Correction on Glioma Characterization
(Journal article; Peer reviewed, 2021)Diffusion MRI is a useful tool to investigate the microstructure of brain tumors. However, the presence of fast diffusing isotropic signals originating from non-restricted edematous fluids, within and surrounding tumors, ... -
Effects of multiple mating and male harassment on female fecundity and longevity in the seed beetle Callosobruchus maculatus.
(Master thesis, 2019-12)Polyandry is a common mating system in many species, however females may experience considerable costs related to multiple mating including male harassment, energy use and in some cases physical damage. Male harassment of ... -
Effects of near-surface thawing on elastic properties and signatures of seismic surface waves
(Master thesis, 2023-09-04)The ongoing temperature rise in the Arctic may have severe effects on large areas of today’s permanently frozen ground. Therefore, it is important to establish robust systems that can monitor permafrost changes with time. ... -
Effects of negative shear on loads for a 15 MW offshore wind turbine during low-level jet events
(Journal article; Peer reviewed, 2023)Wind turbines are more often interacting with the negative shear region of a low-level jet due to increasing turbine sizes. However, the effects of negative shear on wind turbines are not sufficiently studied, particularly ... -

Effects of nuisance submerged vegetation on the fauna in Norwegian rivers
(Journal article; Peer reviewed, 2021)The abundance of aquatic vegetation is increasing in rivers and lakes worldwide. The aim of this study was to find how the macrophyte Juncus bulbosus Linnaeus affects salmonids and benthic macroinvertebrates in Norwegian ... -
Effects of perceived predation risk on extra-pair mating in blue tits (Cyanistes caeruleus)
(Master thesis, 2017-10-28)Trivers’ theory of sexual conflict in parental investment has laid the groundwork for immense quantities of research, especially within the avian taxa. Although male benefits of extra-pair copulation (EPC) are argued to ...
