Current Ph.D projects
About 20,000 years ago an ice sheet covered northern Europe including most of the North Sea. As the ice receded, a landscape visibly scarred by the movements of the glaciers was revealed.
Science communication is a fundamental task for the Norwegian University Museums. However, today`s information society brings new challenges to the old museum institutions, as traditional criteria for presenting science to a wider public no longer seem sufficient in competition with more entertaining types of media.
The PhD-project "Dwellings and societal changes during the Late Mesolithic" is rooted in the archaeological record of the Ormen Lange Project, which took place in Nyhamna on the island Gossen in North-West Norway in 2003-2004.
The dipteran family Chironomidae, also called non-biting midges, is the most ubiquitous and usually most abundant insect group in all types of freshwater and even saltwater, with more than 6000 species worldwide. Due to their high diversity, they are useful in biomonitoring of freshwaters; and since larval head capsules are preserved in lake sediments, they are useful in climate reconstructions.
The influence on physiology and environmental variables on the migration patterns and habitat use of brown trout
In coastal areas where Brown trout (Salmo trutta L.) have free access to the sea, some individuals remain as residents in the watercourse, while other conspecifics conduct periodical feeding migrations to the marine habitat. Whether an individual becomes resident or anadromous (often termed as sea trout) is affected both by genetic and environmental variables.
To study some of the complicated interactions between large herbivores, vegetation, and climate, we compare field measurements made inside and outside large exclosure fences that have been erected on recent logging sites. By using long-term ecological data collected in several different forest types with known herbivore densities, we hope to be able to explain the observed differences in forest development.
