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 ... -
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 ... -
Mercury pollution in fish and invertebrates in natural and wildfire impacted lakes in Norway
(Doctoral dissertations at TUC;2014:8, Doctoral thesis; Peer reviewed, 2014-11-14)Mercury (Hg) contamination in fish has become a global issue and remains a major problem of concern in the Nordic countries, with atmospheric long-range transport of Hg being the main source to aquatic ecosystems. Most Hg ... -
The microbiology and geochemistry of a landfill-contaminated aquifer
(Doctoral dissertations at the University of South-Eastern Norway;107, Doctoral thesis, 2021-10-20)Thousands of aquifers worldwide have been polluted by landfill leachates and many more remain threatened. However, the ecology of these perturbed aquifers remained understudied. The current study incorporates aspects of ... -
Modelling and characterization of climate, environment, and human impact during the Holocene and Eemian using an Interactive Physical Downscaling
(Doctoral dissertations at the University of South-Eastern Norway;199, Doctoral thesis, 2024-06-26)The study of the past climate is important as it provides valuable information about how the earth’s climate has changed over long timescales and helps scientists to better understand natural climate processes and distinguish ... -
Natural and human-induced impacts on the genetic structure of Eurasian reindeer
(Doctoral dissertations at the University College of Southeast Norway;11, Doctoral thesis, 2017-03-17)Geografisk variasjon hos arter og populasjoner er basert på genetisk variasjon, som videre er grunnleggende for naturstyrt evolusjon. Genetisk variasjon og struktur er styrt av faktorer som mutasjoner, seleksjon og genetisk ... -
Naturen som arena for utforsking og læring av naturfaglege tema i barnehagen og i barneskulen
(Doctoral thesis, 2021-05-15)Barn lærer best når læringa tek utgangspunkt i noko barna sjølve er interesserte eller engasjerte i, og når dei får ta aktivt del i eigen læringsprosess. Naturen er ein arena som synest å stimulerer barn si nysgjerrigheit ... -
Observing animal behaviour and movement patterns remotely: A case study using bio-logging technology on free-ranging Eurasian beavers (Castor fiber)
(Doctoral dissertations at the University College of Southeast Norway;10, Doctoral thesis, 2017-02-24)Understanding animal behaviour is a fundamental part of biology and has been revolutionized by the invention of bio-logging units, which can be used to study wild animals in their natural habitats. In this thesis, tri-axial ... -
Spatio-temporal foraging behavior, habitat selection and impacts of bio-logging on Eurasian beavers, Castor fiber
(Doctoral dissertations at the University of South-Eastern Norway;126, Doctoral thesis, 2022-06-28)Wild animals deal with a dynamic landscape consisting of both food resources and threats that vary across space and time. This thesis investigated spatio-temporal foraging behavior and habitat selection of Eurasian beavers ... -
Territorial movement behaviour in the Eurasian beaver
(Doctoral dissertations at the University of South-Eastern Norway;162, Doctoral thesis, 2023-06-09)It can be challenging to observe and quantify natural behaviour in wild free-ranging animals. Species that are reclusive or exploit multiple environments, such as semi-aquatic mammals, may be particularly difficult to ... -
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, ... -
The effect of training intensity, age and diet on aerobic capacity and metabolic risk factors: testing procedures and training interventions
(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 ... -
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 ... -
The importance of snow for mountain vegetation in the Hardangervidda area (Southern Norway): plant distribution, plant phenology, plant diversity, and effects of global climate change
(Doctoral dissertations at TUC;2013:4, Doctoral thesis; Peer reviewed, 2013-06-21)Snø er en av de viktigste faktorene for fjellvegetasjon. I fjellet forårsaker den varierende topografien og dens interaksjon med klimatiske faktorer en ujevn fordeling av snøen. Fordeling av snø og snøsmeltingsmønsteret ... -
