Landscape-scale determinants and dynamics of large carnivore density
(PhD Thesis;2023:36, Doctoral thesis, 2023)1. Wildlife populations live in increasingly human-altered landscapes. Either because of their intrinsic values or due to instrumental values to humans, wildlife populations are monitored to inform about their current ... -
Landscape-scale determinants and dynamics of large carnivore density
(PhD thesis;2023:36, Doctoral thesis, 2023)Wildlife populations live in increasingly human-altered landscapes. Either because of their intrinsic values or due to instrumental values to humans, wildlife populations are monitored to inform about their current status ... -
Large carnivore responses to human activity and infrastructure at multiple scales in Scandinavia
(PhD Thesis;2021:94, Doctoral thesis, 2021) -
Large-area forest productivity estimation using bitemporal data from airborne laser scanning and digital aerial photogrammetry
(PhD Thesis;2020:37, Doctoral thesis, 2020)Site index (SI) indicates the magnitude of timber production that can be realized at a given site and is a crucial variable in forest planning. In Norwegian forest management inventories, SI is commonly quanti ed with large ... -
Late Weichselian glacial dynamics and retreat patterns of the Fennoscandian Ice Sheet in Gausdal Vestfjell, southcentral Norway, acquired from spatial data
(PhD thesis;2018:68, Doctoral thesis, 2018)Evidence-based geomorphological research (analyses of glacial landform record) is one of the commonly used types of glacial reconstructions applied for studying the past ice sheets. The work covered by this thesis contains ... -
Leveraging non-invasive monitoring of carnivores using hierarchical models
(PhD thesis;2020:59, Doctoral thesis, 2020)The development of non-invasive approaches for monitoring wildlife populations made it feasible to obtain ecological parameters across landscapes and populations, rather than a few locations or individuals. The two most ... -
Lichen ecohydrology : from water uptake and storage to climate-driven growth rates and distribution patterns
(PhD Thesis;2020:15, Doctoral thesis, 2020)Lichens are optimized to exploit various combinations of hydration sources, such as rain, dew, fog and humid air. Both intra- and interspecific variability in lichen traits reveal the ability to which lichens can acclimatize ... -
LiDAR, habitat structure and the ecology of ungulates in a landscape of fear
(PhD Thesis;2015:5, Doctoral thesis, 2020-11-10)The expression ‘landscape of fear’ describes a situation in which prey behavior and space use across the landscape are shaped by spatial and temporal patterns in predation risk. Yet such behavioral and indirect effects of ... -
Marine transport modeling of radionuclides using a dynamic speciation approach
(PhD Thesis;2019:42, Doctoral thesis, 2019)Anthropogenic radionuclides are introduced to the marine environment from many sources, such as atmospheric fallout, direct releases from nuclear installations (either via operational or accidental discharges) and indirectly ... -
Microplastic particles from roads and traffic : occurrence and concentrations in the environment
(PhD Thesis;2022:34, Doctoral thesis, 2022)The impact of roads and traffic on the environment have been studied for several decades, and negative impact on both the terrestrial and aquatic environment from pollutants have been demonstrated. Road pollution is typically ... -
Mitigation of greenhouse gas emissions by pH management of agricultural soils in Norway
(PhD thesis;2023:2, Doctoral thesis, 2023)Liming has been and still is used to neutralize soil acidity, improve soil nutrient availability, increase yields, and recently it has been recognized as a possible nitrous oxide (N2O) mitigation tool for arable soils. ... -
Mobility of naturally occurring radionuclides and stable elements in alum shale : a case study of Gran, Highway 4, Norway
(PhD Thesis;2019:72, Doctoral thesis, 2019) -
Modelling and estimating tree and forest resources of the Dry Afromontane forests in South-central Ethiopia using field and remotely sensed data
(PhD Thesis;2020:58, Doctoral thesis, 2020)For effective forest management missions, the presence of accurate information about the forest resources is indispensable. However, the absence of such relevant information for most natural forests in Ethiopia have been ... -
Modelling forest sector impacts of increased use of wood-based bioenergy in Europe and US South
(PhD Thesis;2019:01, Doctoral thesis, 2019)The European Union (henceforth, EU) is now well on track to meet the 2020 targets for renewable energy production and consumption, and recently a new 2030 Framework for climate and energy has been proposed. The forest ... -
Modelling infiltration dynamics in the frozen unsaturated zone : implications for flood hazard
(PhD thesis;2024:25, Doctoral thesis, 2024)This PhD research investigated numerical modelling of frozen soil, implications of soil freezing on infiltration, snowmelt flooding in an agricultural landscape, and literature on soil freezing physics. The main goal was ... -
Modelling radionuclide transfer along terrestrial food-chains : conceptual enhancements and region-specific adaptations
(PhD thesis;2024:74, Doctoral thesis, 2024)Models are one of the key tools employed by emergency and response organizations. They play an important role in the assessment of the potential consequences of a nuclear accident and prognosis of its possible progression. ... -
Nitrous oxide emission and turnover in arable cropping in South East Norway
(PhD Thesis;2020:18, Doctoral thesis, 2020)Nitrogen is essential for all life on Earth. With an increasing global population, the use of reactive nitrogen has increased over the last century, resulting in increasing nitrogen pollution. Leaching of nitrate (NO3-) ... -
Nordic district heating and energy system flexibility : challenges and opportunities
(PhD Thesis;2019:81, Doctoral thesis, 2019)This thesis presents framework conditions for Nordic district heating and barriers and opportunities for flexibility in the district heating – electricity interface. District heating has advantages and disadvantages. ... -
A novel framework for coupling mesoscale and steady-state CFD models for wind resource assessment
(PhD Thesis;2020:30, Doctoral thesis, 2020)The estimation of the energy production of wind farms is a key factor for the development of wind energy projects. Currently, these estimations utilize only a few onsite measurement points to estimate the wind resource at ... -
Novel organic contaminants in recycled organic waste and their fate in a mushroom production system
(PhD thesis;2024:3, Doctoral thesis, 2024)Biogas production is a common treatment method for organic waste in Norway. The waste is anaerobically degraded, to stabilize the waste and to produce renewable energy (biogas). Most of the nutrients in the waste are ...
