Tree species effects on litter decomposition and soil carbon
(PhD thesis;2022:18, Doctoral thesis, 2022)Boreal forests soils play an important role in mitigating climate change as they are the largest terrestrial carbon pool. The accumulation of soil carbon is regulated by the balance of carbon and nitrogen input from plant ... -
Impact of low dose rate ionising radiation : studies in mice evaluating immediate and long-term molecular responses and transgenerational genomic instability
(PhD Thesis;2023:40, Doctoral thesis, 2023)Mye av det vi vet om risiko for helseeffekter etter å ha blitt usatt for ioniserende stråling er kunnskap lært fra de som overlevde atombombene i Hiroshima og Nagasaki. Imidlertid er denne kunnskapen basert på effekter ... -
Soundscape analysis for biodiversity monitoring in tropical rainforest ecosystems
(PhD Thesis;2023:71, Doctoral thesis, 2023)Tropical rainforests harbour up to 66% of the world’s terrestrial biodiversity but have been reduced in extent by up to 60% due to persistent deforestation and forest degradation, resulting in the population decline or ... -
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 ... -
Subsoil nitrogen utilization and N₂O formation in Norwegian grass-clover forage systems
(PhD thesis;2023:7, Doctoral thesis, 2023)Value creation in Norwegian agriculture is primarily based on milk and meat production, which depend in part on perennial grassland-based forage production. Roughly 60% of the fully cultivated land in Norway is used for ... -
Strategies for increasing sustainability of wheat (Triticum aestivum L.) and faba bean (Vicia faba L.) production : effect of composts, rotation and biofertilizers
(PhD Thesis;2023:21, Doctoral thesis, 2023)An increasing human population poses extraordinary challenges on agricultural production. Feeding an estimated 10 billion people by 2050 requires more food with good nutritious value. Synthetic fertilizers and herbicides ... -
The European energy transition : economic impacts on Nordic stakeholders in the energy system
(PhD thesis;2023:27, Doctoral thesis, 2023)This thesis assesses the economic impacts that the European energy transition towards net-zero carbon emissions has on Nordic power system stakeholders. The impacts of climate policies, the role of power system flexibility, ... -
Demand flexibility in electricity markets
(PhD Thesis;2021:1, Doctoral thesis, 2021)Demand flexibility integration is an important measure for the decarbonization of energy systems and a more efficient use of resources. Demand flexibility can provide multiple benefits to the power system and reduce system ... -
On-site treatment options for recovery of nutrients in dry toilets
(PhD Thesis;2022:48, Doctoral thesis, 2022)Animal and human excreta had a major role in the development of agriculture in the past, but their role was lost with the development of the modern waterborne sanitation and inorganic fertilizers. To re-envision human ... -
How green is the green shift? : the potential effects of a bioeconomy on ecosystem services in Nordic catchments
(PhD Thesis;2021:67, Doctoral thesis, 2021)In light of the increasing pressures from human activities on ecosystems and the global climate, the Nordic countries have decided that a green shift is necessary to ensure the future wellbeing of society. The transition ... -
The importance of invertebrates on fungi in dead wood
(PhD Thesis;2022:43, Doctoral thesis, 2022)Dead wood is an important energy source in boreal forests and it hosts a high biodiversity dominated by fungi and invertebrates. Wood decay fungi are the initial decomposers of dead wood and invertebrates interact with ... -
Fine-spatial radiation measurements for heterogeneous boreal–alpine and sub-alpine vegetation
(PhD Thesis;2022:37, Doctoral thesis, 2022)Net radiation constitutes the most important component shaping the climate in the lower atmosphere and the land surface below. The flux determines the amount of energy available for exchange as sensible and latent heat, ... -
Biochar for N2O mitigation and improved delivery and retention of mineral nitrogen in compost and soil
(PhD Thesis;2022:15, Doctoral thesis, 2022)Biochar is a promising technology for simultaneously storing carbon in soils, improving crop yields and reducing greenhouse gases. In the last 20 years, research efforts into biochar and its application to soils have been ... -
Emerging challenges in the energy transition in Northern Europe : potentials and impacts
(PhD Thesis;2022:25, Doctoral thesis, 2022)The European energy transition has passed the initial stage, and both the speed and scope of decarbonisation are growing rapidly. Decarbonisation progress has been observed in the power sector, but stronger efforts are ... -
Characterization of radioactive particle exposure using micro and nano-focused X-ray techniques
(PhD Thesis;2021:95, Doctoral thesis, 2021)Radionuclides may be introduced into the environment from a variety of sources both naturally occurring, such as weathering from ore deposits, and anthropogenic, such as releases associated with the nuclear weapons and ... -
Forest disturbance and tree species elevation ranges in Costa Rica
(PhD Thesis;2021:99, Doctoral thesis, 2021)The role of disturbance in influencing interspecific competition and species persistence and distributions remains surprisingly unexplored. Disturbance may increase elevation ranges, especially at the lower range limits, ... -
The role of biotic and abiotic factors on treeline ecotone dynamics : studies using field observations and remote sensing
(PhD Thesis;2022:35, Doctoral thesis, 2022)With global warming, the forest extent is expected to change, and the transition zone between the upper forest boundary and treeless alpine landscape (i.e., the treeline ecotone) is expected to migrate to higher elevations. ... -
Impact of climate and agricultural management on hydrology and water quality : a headwater catchment scale approach
(PhD Thesis;2021:77, Doctoral thesis, 2021)Eutrophication and degradation of water quality are global problems and affect many freshwater and coastal systems. Agricultural areas are major contributors of nutrients and soil particles in streams and lakes. The ... -
Participant experiences in wildlife watching tourism
(PhD Thesis;2021:43, Doctoral thesis, 2021)This dissertation contributes to the wildlife watching tourism literature by investigating which elements are important to participants’ overall experiences and how these elements can contribute to the desired outcomes ... -
Veteran oaks, biodiversity and ecosystem functioning in southern Norway
(PhD Thesis;2021:29, Doctoral thesis, 2021)Veteran trees are keystone structures in landscapes, hotspots for biodiversity and have high cultural value. They are also declining globally, and this threatens the species that are dependent on them, and the ecosystem ...
