(Doctoral dissertations at the University College of Southeast Norway;13, Doctoral thesis, 2017-04-21)BACKGROUND: Low cardiorespiratory fitness (CRF) with accompanying metabolic risk factors such as overweight/obesity, reduced blood glucose control, elevated blood pressure, and dyslipidemia, is one of the most important ... -
Territoriality and life history strategies of the Eurasian beaver
(Doctoral dissertations at the University College of Southeast Norway;24, Doctoral thesis, 2017-09-29)We studied life history strategies in the Eurasian beaver (Castor fiber), a territorial, monogamous, long-lived mammal, to increase our understanding of the mechanisms and trade-offs affecting the onset of natal dispersal, ... -
Mercury in freshwater biota in southeastern Norway, with special emphasis on potential antagonistic effects of selenium on mercury bioaccumulation
(Doctoral dissertations at the University College of Southeast Norway;23, Doctoral thesis, 2017-10-06)Mercury (Hg), and in particular methylated Hg (methyl-Hg, MeHg), because of its high potential for bioaccumulation and biomagnification in aquatic food webs, generate health risks to both aquatic top predators and humans ... -
The effects of harvest on the sociospatial and genetic structure of a solitary-living large carnivore, the brown bear Ursus arctos
(Doctoral dissertations at the University College of Southeast Norway;28, Doctoral thesis, 2017-10-20)Understanding the effects of harvest is integral for sustainable wildlife management and conservation. And yet, the focus of managers has predominantly been on the direct mortality of harvest, often ignoring the indirect ... -
Importance of air and soil temperatures for bioclimatic delimitations in Norwegian mountains
(Doctoral dissertations at the University of South-Eastern Norway;4, Doctoral thesis, 2018-06-18)Distribution limits of plants in relation to climatic variables have long interested ecologists. High latitudes and altitudes house distribution limits of forests, treelines, treeline ecotones and vascular plants in alpine ... -
Kontekst for læring. Nærmiljø som læringsarena i utdanning for bærekraftig utvikling
(Doktoravhandlinger ved Universitetet i Sørøst-Norge;23, Doctoral thesis, 2019-02-04)Verden i dag står overfor store miljømessige og sosiale utfordringer som får konsekvenser for framtidas samfunn, lokalt og globalt. Derfor vil det være av stor betydning å utdanne elever som både får nødvendige kompetanser ... -
Ecology of Alpine Lichen Heaths: Relationships Between Vegetation, Soil Temperature, and Edaphic Factors in Southern Norway
(Doctoral dissertations at the University of South-Eastern Norway;29, Doctoral thesis, 2019-03-01)Alpine lichen heaths are found on nutrient-poor and deep soils in the mountain plateaus in southern Norway. These are generally characterized by terricolous or so-called “mat-forming” lichens dominated by those in the ... -
Arctic charr (Salvelinus alpinus) farming in southern Norway
(Doctoral dissertations at the University of South-Eastern Norway;85, Doctoral thesis, 2021-02-03)Arctic charr (Salvelinus alpinus) is a stenothermic cold-water fish with a circumpolar distribution.
