Effects of environmental complexity during rearing and laying on fearfulness, spatial cognition and neural plasticity in laying hens
(PhD Thesis;2023:56, Doctoral thesis, 2023)Due to an increased demand from citizens, the egg industry in the European Union is moving towards more welfare friendly housing systems. However, these environments are often more complex, and hens are still exposed to ... -
Effects of environmental enrichment on social cohesion, aggressive behavior and telencephalon cell proliferation in Atlantic salmon parr
(Master thesis, 2023)Much is known about the life cycle and growth of the Atlantic salmon, but there has been less focus on the behaviour and neurobiology of these animals in captivity and how they interact with each other and their environment. ... -
Effects of environmental pollutants on calcium release and uptake by rat cortical microsomes
(Journal article; Peer reviewed, 2018) -
Effects of extruded pellets on physical feed quality and digestion behavior in dairy cows
(Master thesis, 2018)This thesis consists of a literature study and a presentation of an experimental work. The literature review contains knowledge of raw ingredients, rumen digestion of starch and protein and feed processing techniques. The ... -
Effects of fat soluble vitamins on viral infection and antiviral responses in Atlantic salmon (Salmo salar L.) erythrocytes
(Master thesis, 2017)Viral diseases are vital challenges in the aquaculture industry. In Norway, heart- and skeletal muscle inflammation (HSMI) is one of the major viral diseases affecting Atlantic salmon. In mammals, low vitamin D has been ... -
Effects of feeding naturally contaminated deoxynivalenol diets to sows during late gestation and lactation in a high-yield specific pathogen-free herd
(Peer reviewed; Journal article, 2018) -
Effects of fertilization and time of plowing on nitrous oxide emissions in arable soil in SE Norway
(Master thesis, 2012-04-27)The agricultural sector has been identified as a major anthropogenic source for the greenhouse gases N2O, CH4 and CO2 by the Intergovernmental Panel on Climate Change (IPCC, 2007). Although N2O only accounts for around ... -
Effects of field plot size on prediction accuracy of aboveground biomass in airborne laser scanning-assisted inventories in tropical rain forests of Tanzania
(Journal article; Peer reviewed, 2015) -
Effects of fire history on species richness and carbon stocks in a Peruvian puna grassland, and development of allometric equations for biomass estimation of common puna species
(Master thesis, 2011-09-09)High-elevation ecosystems have recently received increasing attention from the carbon financing sector. This has sparked the need for reliable and non-destructive methods to estimate carbon stocks in these ecosystems. The ... -
Effects of forest fire on production of down woody debris in Aust-Agder County in Norway
(Master thesis, 2011-10-07)Forest fires have played an important role in structuring the boreal conifer forest. Forest fires produce dead wood, which is important for biodiversity. Many species, including Red List species, are dependent on dead wood ... -
Effects of forest management history on fine roots and mycorrhizal colonization in Norwegian boreal spruce forests
(Master thesis, 2023)Fine roots play critical roles in carbon cycling in boreal forests. However, they are poorly represented in the studies of forest management effects on forest soil, likely due to the labour- intensive methods of soil ... -
Effects of forest structure and airborne laser scanning point cloud density on 3D delineation of individual tree crowns
(Peer reviewed; Journal article, 2016) -
Effects of forestry, predators and weather on capercaillie (Tetrao urogallus) and black grouse (Lyrurus tetrix) in South-East Norway
(Master thesis, 2017)The European populations of capercaillie (Tetrao urogallus) and black grouse (Lyrurus tetrix) have declined the last 50 to 100 years. The decline has happened at the same time as changes in forestry practices, predation ... -
Effects of fork length on the utilization distribution and habitat preferences of anadromous Arctic charr (Salvelinus alpinus) in a sub-arctic lake
(Master thesis, 2021)This was an acoustic telemetry study investigating lacustrine habitat utilization of anadromous population of Arctic charr (Salvelinus alpinus) located in Storvatnet in Hammerfest multiplicity northern Norway. Arctic charr’s ... -
Effects of Formic Acid Preservation of Fishbones on the Extractability of Ammonium Lactate–Acetate Soluble Calcium, Phosphorus, Magnesium, and Potassium
(Peer reviewed; Journal article, 2022)Fishbones contain significant amounts of plant nutrients. Fish residues may be preserved by acidification to pH < 4, which may affect the chemical extractability, and the plant availability of nutrients when applied as ... -
Effects of four environmental pollutants on Syrian hamster embryo cells
(Master thesis, 2013-07-12)Hensikten med denne studien var å undersøke de tre kjemikaliene Perfluorooctane sulfonate (PFOS), Perfluorononanoic acid (PFNA) og Tetrabromobispehenol-A (TBBPA) sitt karsinogene potensiale. Dette ble gjort ved å utføre ... -
Effects of functional ingredients from yeast in diets for Atlantic salmon (Salmo salar), from two genetic backgrounds, on growth performance and nutrient utilization
(Master thesis, 2021)The overall aim of this thesis was to determine effects of functional ingredients in diets for Atlantic salmon, extracted from non- saccharomyces yeast, on growth performance and feed utilization. A 13 week (7 weeks in ...
