Cod on the dive : investigating Atlantic cod of the Inner Oslofjord during population decline
(Master thesis, 2021)The Atlantic Cod population of the Inner Oslofjord is in the midst of a collapse and a catch ban has been in effect since 2019. This project was designed to study demography, population size and migration in the Atlantic ... -
Condensed tannins in senesced foliage and soil organic layer in response to fertilization in boreal forest ecosystem
(Master thesis, 2021)Anthropogenic nitrogen deposition rate in boreal forests increased over the last century and significantly impacted many parts of these ecosystems. Boreal forests contain a large amount of carbon (C), and nitrogen (N) is ... -
Evaluating wildlife cameras as a method to sample reindeer behavior
(Master thesis, 2021)Increasing amounts of infrastructure intersecting reindeer habitat in Fennoscandia also increases concern over negative effects on reindeer behavior and area use. Previous studies have shown variable results regarding area ... -
Population estimate, trend and habitat preferences of breeding curlews (Numenius arquata) in Akershus, southeast Norway
(Master thesis, 2018)The Eurasian Curlew (Numenius arquata) is a species in decline, classified as near threatened (NT) worldwide, and vulnerable (VU) in Norway. In the region of Akershus (SE Norway), no recent update exists of the breeding ... -
Priming of inducible defenses in Norway spruce : effects of putative defense priming chemicals on tree resistance against the bluestain fungus Grosmannia penicillata and insights into the underlying mechanisms
(Master thesis, 2021)Priming of inducible defenses in Norway spruce could be a cost-effective strategy to protect trees from herbivores and pathogens. In this study, my aim was to identify chemical priming agents that can increase the resistance ... -
Seasonal variation in chemical composition of Chamerion angustifolium pollen as measured by Fourier-Transform Infrared Spectroscopy
(Master thesis, 2019)The quality of pollen is of fundamental importance for male reproductive success in spermatophytes, but our knowledge as to whether pollen quality is plastic and varies throughout the flowering season is limited. Pollen ... -
Short-term effects of Salix plantings and seeding of Festuca ovina on vegetation recovery in a disturbed alpine heathland in the Dovre Mountains, Norway
(Master thesis, 2020)Alpine ecosystems are particularly vulnerable to anthropogenic disturbances and have a slow natural recovery rate. Open questions remain as to which forms of active restoration measures could accelerate alpine ecosystem ... -
Stående og induserbart fenolforsvar hos kulturplanter og naturlig foryngelse av gran (Picea abies)
(Master thesis, 2020)Foryngelse er et viktig tiltak for å sikre bærekraftig forvaltning av skogen. Gran (Picea abies) forynges i hovedsak ved hjelp av foredlede planter som gir økt skogproduksjon sammenlignet med naturlig foryngelse. Gransnutebilla ... -
The hunt for maternity colonies : a pilot study of using radio telemetry to track bats in southeast Norway
(Master thesis, 2018)There is still a gap of knowledge regarding bats in Norway. More studies are needed to explore which habitats are important for the maternity colonies, and which methods are most suited to find them. This is especially ...
