Drivers of spatial variability in spring bloom onset and magnitude along a latitudinal gradient in the Nordic Seas
(Master thesis, 2018-06-21)Spring phytoplankton blooms in the Nordic Seas contribute a large proportion of global primary production, and their timing and magnitude heavily impacts higher trophic levels. Two key drivers of bloom development, ... -
Driving forces in the distributions of the three most common deep-water coral species in Norway: Lophelia pertusa, Paragorgia arborea, and Primnoa resedaeformis
(Master thesis, 2017-12-20)This thesis explores a set of environmental variables may be used to predict the spatial distribution of the three most common cold-water coral (CWC) species in Norway: Lophelia pertusa, Paragorgia arborea, and Primnoa ... -
The effect of aerobic training on growth, muscle development and heart condition in Atlantic salmon (Salmo salar) post-smolts in large-scale semi-closed containment systems.
(Master thesis, 2017-06-24)Exposing fish to moderate water currents as a form of exercise is often perceived as positive for fish welfare, growth, muscle development and heart condition. This thesis examines what effect rearing Atlantic salmon (Salmo ... -
The effect of climate variation and food availability on breeding success in Atlantic puffins at Hjelmsøya, Northern Norway
(Master thesis, 2016-05-27)The colony of Atlantic puffins (Fratercula arctica) at Hjelmsøya, in Northern Norway has experienced extensive annual fluctuations in breeding success. To investigate how climate variability affects the population dynamics ... -
The effect of foraging ecology on the onset of dawn song for passerine species
(Master thesis, 2018-11-20)Passerine birds have a burst of energetic singing prior to sunrise during the breeding season, called the dawn chorus. In this thesis, I examine how interspecific differences in foraging ecology can explain the scheduling ... -
The effect of grazing and hiking on the elevational range shift of vascular plant species in the Scandes during recent decades
(Master thesis, 2016-06-01)Resurvey of historical plant distribution data can provide valuable information about how plant communities have changed, a topic which is of great interest due to recent decades of climate and land use change. Range shifts ... -
The effect of halide salts on the uptake, deposition and depuration rate of radioiodine in zebrafish (Danio rerio)
(Master thesis, 2013-07-01) -
The effect of hydrodynamics on benthic macrofaunal composition and functioning under salmon fish farms
(Master thesis, 2015-08-17)The fish farming industry has continued to increase over the last years, and salmon fish farms in Norway continue to grow in numbers. With this growing aquaculture, there is also a larger need to quantify the environmental ... -
The effect of plant proteins and vegetable oils on the sterol metabolism of Atlantic salmon (salmo salar)
(Master thesis, 2011-05-27)To ensure responsible use of the valuable marine ingredients a major effort is being invested in understanding effects of replacing fish meal and fish oil partially or completely with plant proteins and vegetable oils in ... -
Effect of tag weight on vertical behavior of Atlantic salmon (Salmo salar) smolts: an overlooked tag effect?
(Master thesis, 2021-06-01) -
Effects of Fertilizers on the Species Composition of Bryophytes in Grazed Pastures in Rogaland, Norway
(Master thesis, 2014-06-02)This study has aimed at looking at how the species composition of bryophyte communities in grazed pastures is affected by fertilizers. Bryophyte species were collected from 25 different sites in Rogaland in Norway, of which ... -
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 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 ... -
The effects of persistent organic pollutants (POPs) on the steroidogenesis in the mouse Y1 adrenocortical cell line
(Master thesis, 2015-10-01)The endocrine system refers to glands which secrets hormones that regulates a variety of physiological processes. The adrenal cortex is part of the endocrine hypothalamus-pituitary-adrenal axis, and produces and secretes ... -
Effects of rapid temperature changes on Atlantic salmon, Salmo salar, post-smolts
(Master thesis, 2017-06-28)Year round production of Atlantic salmon post-smolts in closed or semi-closed systems opens up for use of seawater from different depths, which will permit stocking of fish from closed containment system to the open sea ... -
