Annual variation in the diet of the European shag (Phalacrocorax aristotelis) at Sklinna, central Norway, and a possible relationship between reproduction and abundance of year class 1-saithe in the diet
(Master thesis, 2011-05-09)Monitoring of seabirds is an important task due to large current environmental and ecosystem changes which have affected many species of seabirds severely through affecting their food supplies. Declines in food supplies ... -
Anrikning og omsetning av metaller i innsjøer utsatt for veiavrenning, studert med paleolimnologiske metoder
(Master thesis, 2018)Ved hjelp av paleolimnologiske metoder kan man undersøke metallkonsentrasjonene for de ulike lag i en sedimentsøyle og hvordan konsentrasjonene har endret seg over tid. En uforstyrret sedimentsøyle som går langt tilbake i ... -
Anthocorid bugs (Hemiptera, Anthocoridae) as natural predators of apple aphids and pear psyllids using spatial and temporal scales
(Master thesis, 2016-09-02)Farmers in Norway are facing challenges like reduced access to pesticides, climate change and problems associated with increased homogeneity of crops in farming. Biological control may provide a solution to these challenges, ... -
Anthropogenic effects on spatiotemporal activity patterns and interactions in a predator-prey assemblage
(Master thesis, 2016-08-31)Evidence is accumulating that human presence and anthropogenic features in the environment impact the spatiotemporal activity patterns of both predators and prey. This is liable to affect predator-prey interactions, one ... -
Antioxidant enzyme system in fish from contaminated lakes in Chernobyl exclusion zone
(Master thesis, 2020)Akvatiske organismer i Tsjernobyl-eksklusjonssonen har blitt kronisk eksponert for ioniserende stråling siden atomkraftulykken i Tsjernobyl i 1986. Fisk anses som de mest radiosensitive akvatiske organismene, og i den høyt ... -

Applicability of natural porous materials and lime with conditioning and sorption properties for wastewater treatment
(PhD Thesis;2016:77, Doctoral thesis, 2016)Urban wastewater streams are produced in large quantities and removal of contaminants is required for compliance with environmental regulations. The water separation, concentration of particles as solid phases (e.g., ... -
Application of Aerogel-based plaster for refurbishment and preservation of a listed historic masonry building in Norway : an in-situ energy efficiency study
(Master thesis, 2018)This thesis examines the energy efficiency effects of refurbishing historic masonry buildings in a Norwegian climate with the use of an aerogel-based plaster (FIXIT222) for cold side insulation. Additionally, it aims to ... -
Application of waterborne electrical resistivity tomography and ground penetrating radar in the delta area of Numedalslågen, Norway
(Master thesis, 2018)Two non-invasive geophysical methods have been tested in the lowermost reaches of the river Numedalslågen, Southern Norway. The aim were to estimate thickness of sediments, possible layering and the depth to the bedrock. ... -
Arctic fox (Vulpes Lagopus) use of feeding dispensers and bait stations in Central Norway : impact of intra-guild competition and rodent abundance
(Master thesis, 2015-03-10)Despite being protected since 1930 in Norway, the arctic fox has not recovered. The small population size, lack of food availability and competition by the red fox are suggested to be the main reason inhibiting the recovery. ... -
