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 ... -
Cultivating conflict : perspectives on the human dimensions of voluntary Atlantic salmon (Salmo salar) hatcheries in a conservation context
(PhD Thesis;2018:76, Doctoral thesis, 2018)The overall goal of this thesis is to offer a more in-depth human dimensions understanding of voluntary Atlantic salmon hatcheries, focusing on the underlying drivers of conflict over hatchery use in a conservation context. ... -
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 ... -
Density and bending properties of Norway spruce (Picea abies (L.) Karst.) structural timber – Inherent variability, site effects in machine strength grading and possibilities for presorting
(PhD Thesis;2016:43, Doctoral thesis, 2020-11-19)Density, modulus of elasticity (MOE) and bending strength (MOR) are the most important properties for structural timber. These properties vary significantly within European species, both between and within countries. The ... -
Drivers of bat activity and habitat use in boreal forest
(PhD thesis;2024:29, Doctoral thesis, 2024)Bat species in Fennoscandia make up approximately 20% of the terrestrial mammal wildlife and are all reliant on forest habitats to some extent throughout their annual cycle. However, there is a lack of knowledge on ecological ... -
An ecological and socio-economical study of a locally endangered tree species, Olea europaea subsp. cuspidata, in a dry Afromontane forest
(PhD Thesis;2018:94, Doctoral thesis, 2018)Afromontane forests are found in the tropics and are often threatened because of land use changes. These forests have various types of multipurpose tree species that provide different services to the local communities. ... -
Ecological impacts of red deer browsing in boreal forest
(PhD Thesis;2018:66, Doctoral thesis, 2018)The populations of wild ungulates are increasing in the northern hemisphere, and in many areas, their populations have developed from critically low to historically high numbers within the last century. There are multiple ... -
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 ... -
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) -
Effects of selective logging on Amazonian wildlife
(PhD thesis;2023:6, Doctoral thesis, 2023)Selective logging of tropical forests is rapidly expanding, making it inevitable that future tropical landscapes will be dominated by production forests. Any biodiversity conservation strategy must consider the potential ... -
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 ... -
Energetics in seasonal environments: reindeer as a case study
(PhD Thesis;2021:74, Doctoral thesis, 2021)How endothermic animals manage and allocate energy to critical processes (maintenance, reproduction, thermoregulation and activity) can determine their success and survival. The balance in energy expenditure related to ... -
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, ... -
Exploring the link between phytoplankton and environmental stressors using lake sediments as archives : a study of Gonyostomum semen’s expansion in Norwegian lakes
(PhD Thesis;2021:45, Doctoral thesis, 2021)Phytoplankton communities are affected as a result of changing environmental conditions in boreal lakes due to global climate change and local human activities. One species currently undergoing change and expansion is the ... -
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, ... -
Flooding matters : structure, above-ground biomass, and carbon stocks of an Amazonian forestscape
(PhD Thesis;2021:50, Doctoral thesis, 2021)Amazonia accounts for approximately half of the world’s tropical forests and one quarter of all terrestrial species. The forests retain and circulate large amounts of water and store carbon. Amazonia is thus extremely ... -
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, ... -
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 ... -
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 ... -
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 ...
