Soil carbon storage in the forest-tundra ecotone : insights from field- and remotely sensed data
(PhD Thesis;2023:84, Doctoral thesis, 2023)Due to climate warming, forests are moving to higher elevations and latitudes at the expense of treeless tundra. Recent studies suggest that these vegetation shifts promote soil organic carbon (SOC) losses that exceed ... -
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 ... -
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 ... -
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 ... -
The effect of biochar in combination with mineral or organic fertilizers on crop production in Nepal
(PhD Thesis;2018:23, Doctoral thesis, 2018)The majority of poor people in Nepal relies on agriculture for employment and livelihood sustenance. Declining soil fertility and ongoing climate change are the key challenges faced by farmers, with adverse effects on crop ... -
Timeliness in seedbed preparation for spring cereals : studies to prepare for climate change in Norway
(PhD Thesis;2019:13, Doctoral thesis, 2019)Future increases in winter and spring precipitation in Norway may exacerbate the dilemma of spring fieldwork that farmers have, concerning topsoil compaction versus delayed sowing on autumn-ploughed soil. Both topsoil ... -
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 ... -
Understanding the structure-function relationship of honey bee Vitellogenin
(PhD Thesis;2022:8, Doctoral thesis, 2022)This thesis focuses on the structure and molecular function of Vitellogenin (Vg) from honey bees (Apis mellifera). Vg is an ancient protein found in animals. Most biological processes depend on proteins' activities, and ... -
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 ... -
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 ... -
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 ... -
