Functional traits and decomposition of lichens, bryophytes and vascular plants in an alpine ecosystem
(PhD Thesis;2019:44, Doctoral thesis, 2019)Functional traits influence how an organism responds to its environment and how this can affect ecosystem processes such as decomposition. The majority of trait-based studies have focused on vascular plants, while non-vascular ... -
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 ... -
Crop pollination by insects in small-scale agroforestry farming in Tanzania
(PhD Thesis;2019:101, Doctoral thesis, 2019)Context. The decline of pollinating insects worldwide threatens pollination services for wild angiosperms and important food crops. The importance of insect pollination services for food production has been documented for ... -
Mobility of naturally occurring radionuclides and stable elements in alum shale : a case study of Gran, Highway 4, Norway

Analyzing aspects of land-use sustainability in Tanzania : current forest degradation, urban charcoal demand, and impacts of future firewood and charcoal consumption
(PhD Thesis;2019:51, Doctoral thesis, 2019)The forest sector plays a significant roles both directly and indirectly in Tanzania. In total 54% of the land area of mainland Tanzania is covered by different types of forests, the main ones being the miombo woodlands, ... -
Forestry and forest management in an uncertain environment : adaptation to climate change in Norwegian forestry
(PhD Thesis;2019:38, Doctoral thesis, 2019)The overall objective of this thesis is therefore to study whether, how, and why (not) risk and uncertainty related to climate change may (or may not) influence the forest management strategies of forestry decision-makers ... -
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 ... -
Functional traits across primary producer groups and their effects on micro-arthropod communities in alpine Norway
(PhD Thesis;2019:71, Doctoral thesis, 2019)The vegetation of alpine ecosystems, i.e. those above the elevation of the tree line, consists not only of vascular plants, but also of non-vascular primary producers such as lichens and bryophytes. The use of functional ... -
Herbivory and climate effects on plant defenses: an ecological and molecular approach
(PhD Thesis;2019:28, Doctoral thesis, 2019)Knowledge of plant defense responses and how they interact with biotic (e.g., herbivores) and abiotic (e.g., temperature) factors is of fundamental importance for understanding ecosystem functioning. Increases in temperature ... -
Effects of conservation farming and biochar on carbon and nitrogen cycling in light textured soils in the sub-humid tropics
(PhD thesis;2019:41, Doctoral thesis, 2019) -
Å legge til rette for naturbaserte reiselivsopplevelser : en studie av forholdet mellom tilbydere, ressurser og produkter
(PhD Thesis;2020:02, Doctoral thesis, 2020)Naturbasert reiseliv er opplevelser, næringsvirksomhet og bruk av ressurser i naturen knyttet til opphold i naturområder. Det omfatter et bredt spekter av steder, aktiviteter og måter å være i naturen på. Det inkluderer ... -
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 ... -
Investigating sensitivity and tolerance to chronic gamma irradiation in the nematode Caenorhabditis elegans
(PhD Thesis;2020:8, Doctoral thesis, 2020)At the cellular level, excitation and ionization of atoms and molecules constitute the fundamental processes leading to harmful effects induced by exposure to ionizing radiation. However, radiosensitivity, defined as the ... -
Assessments of the future role of bioenergy in the Nordic energy and forest sectors
(PhD Thesis;2020:64, Doctoral thesis, 2020)This thesis presents studies that describe different consequences of increased use of forest resources for energy purposes. Forest biomass is widely used in many different applications; in recent years, biofuel has been ... -
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 ... -
Effects of access to renewable energy sources and technologies on rural household energy use and the environment in Ethiopia
(PhD Thesis;2020:50, Doctoral thesis, 2020)Access to modern, affordable, and reliable energy and clean cooking facilities is critical for Ethiopia to drive its economic development, reduce poverty and curb the negative environmental and health impacts of traditional ... -
The conservation value of power-line clearings for native insect-pollinated plants and wild bees in boreal forest landscapes
(PhD Thesis;2020:31, Doctoral thesis, 2020)Worldwide declines in wild pollinators are threatening the provision of vital pollination functions and services to both native plant communities and crops. Habitat loss due to human land use changes is identified as one ... -
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 ... -
Leveraging non-invasive monitoring of carnivores using hierarchical models
