Brown trout anadromy in the Anthropocene
(PhD Thesis;2024:50, Doctoral thesis, 2024)Recent human-induced changes in both marine and freshwater environments are likely to alter adaptative landscapes in migratory species that utilise both habitats. Anadromous salmonids, like the brown trout (Salmo trutta), ... -
Vulnerability and impacts on peatlands and groundwater by tunnelling in crystalline rocks
(Dr.philos Thesis;2017:01, Doctoral thesis, 2017)The overall aim of the thesis was to contribute to improve the understanding and basis for assessments of environmental consequences and vulnerability of peatlands to morphological effects and hydrological changes caused ... -
Geophysical monitoring of redox influenced degradation near the water table
(PhD Thesis;2018:75, Doctoral thesis, 2018)Soil contamination of organic origin is a major environmental challenge. Redox reactions drive organic matter degradation in the ground. Monitoring these reactions is therefore needed to protect soil and groundwater. This ... -
Water storage dynamics of papyrus wetlands and land use change in the Lake Kyoga basin, Uganda
(PhD thesis;2018:69, Doctoral thesis, 2018)Papyrus wetlands of the upper Nile basin in Eastern Africa provide water and fertile soils that are essential to sustain agricultural production. Due to the need to improve food security, there is increased pressure to ... -
Fusion of airborne laser scanning and hyperspectral data for predicting forest characteristics at different spatial scales

Data, models, and insights for informed decision-making in the management of exclosures in Tigray, northern Ethiopia
(PhD Thesis;2018:89, Doctoral thesis, 2018)In Ethiopia, exclosures are rapidly expanding and performing good to reverse deforestation and land degradation. Local communities, particularly in Tigray show a clear preference for exclosures, which are useful for ecosystem ... -
Isocyanic acid : methodologies for generation, sampling and measurement in workroom air
(PhD Thesis;2018:27, Doctoral thesis, 2018)Isocyanates are mainly used industrially for the production of polyurethane (PUR) products. Thermal decomposition of PUR results in the emission of isocyanates. Workers performing hot-work such as grinding, welding and use ... -
Biomass stock and change estimation in boreal forests using remotely sensed data : results from empirical studies and simulations
(PhD Thesis;2017:69, Doctoral thesis, 2017)Airborne LiDAR (Light Detection and Ranging) has become an important remote sensing tool for forest inventory. In the past two decades, this technology has seen a rapid status transition from experimental to operational, ... -
Detection of root, butt, and stem rot in Picea abies with remotely sensed data
(PhD Thesis;2023:28, Doctoral thesis, 2023)Root, butt, and stem rot fungi (RBSR) are among the most significant forest pathogens in Norway. RBSR leads to decay of the tree stem and disruption of vascular tissue. Impaired vascular function reduces tree growth and ... -
Risk and uncertainties incorporated in the management of root and butt rot infected forest areas
(PhD Thesis;2022:75, Doctoral thesis, 2022)Root and Butt Rot (RBR) caused by the pathogenic fungi Heterobasidion spp. is a significant problem affecting Norway's main coniferous tree species, Norway spruce (Picea abies L. Karst) and Scots pine (Pinus sylvestris ... -
Application of external prediction models in forest management inventories based on airborne laser scanning
(PhD Thesis;2022:28, Doctoral thesis, 2022)The use of airborne laser scanning (ALS) data in forest management inventories (FMI) has become operational during the last decades. Since it was introduced, ALS has improved FMI practices due to their capability to describe ... -
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. ... -
Effect of soil and water conservation management on surface runoff, soil erosion, soil fertility and crop yield in southwest Ethiopia
(PhD Thesis;2020:72, Doctoral thesis, 2020)Soil and water are central resources for crop production. Soil erosion by water (water erosion) is a major cause of soil degradation and cropland productivity decline in the world. In Sub-Saharan Africa (SSA), where food ... -
Quantification of genetic and epigenetic variation in phenology and growth in Norway spruce
(PhD Thesis;2020:39, Doctoral thesis, 2020)Norway spruce is a key forest tree species with high economic and ecological importance in northern Europe. Climate change creates a potential for increased productivity but can cause maladaptation of long‐lived trees to ... -
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 ... -
Climate Smart Agriculture in smallholder farming systems in the central rift valley of Ethiopia : potentials for improving productivity, climate change adaptation and mitigation
(PhD Thesis;2019-95, Doctoral thesis, 2019)Climate Smart Agriculture (CSA) is an approach that aims at achieving sustainable food production and security through providing flexible but socially acceptable cultivation methods. For this, CSA seeks to sustainably ... -
Selenium and other minerals in farm animals, feed, fodder crops and soils in Kosovo, and the bioavailability of selenium to animals from crop biofortification
(PhD Thesis;2019:09, Doctoral thesis, 2019)Micro minerals have important functions in plants and animals. Most of the micro minerals are essential for both plant and animal normal growth. However, some of them are only essential for plants, while the others are ... -
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 ... -
Single and combined toxicity of gamma and ultraviolet B radiation in the aquatic macrophyte Lemna minor
(PhD Thesis;2021:8, Doctoral thesis, 2021)Aquatic plants in the natural environment are exposed to background levels of ionizing radiation originating from cosmic radiation and naturally occurring radioactive materials (NORM), as well as technologically enhanced ... -
Assessing condition and changes in forest ecosystems using remotely sensed data
(PhD thesis;2023:63, Doctoral thesis, 2023)Forest ecosystems yield a range of ecosystem services that directly or indirectly contribute to human wellbeing. The potential of forest ecosystems to deliver services is, however, directly related to their condition, or ...
