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 ... -
Environmental impact of fertilization with biogas digestates : studies of inorganic and organic contaminants
(PhD thesis;2018:78, Doctoral thesis, 2018)Sustainable and safe energy and food production are important issues affected by climate change. Biogas production is among the technologies with a potential to reduce negative effects on the environment that increased ... -
Establishing new methods for PSE-like pork defects detection and diagnostics
(PhD thesis;2024:28, Doctoral thesis, 2024)This thesis focuses on establishing innovative tools as new methods for assessing the quality of pork meat (Sus scrofa domestica). The conversion from muscle to meat consists of a complex interaction between factors such ... -
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 ... -
Fusion of airborne laser scanning and hyperspectral data for predicting forest characteristics at different spatial scales

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 ... -
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 ... -
Historical and contemporary drivers of organic soil and charcoal carbon stocks in boreal forests
(PhD Thesis;2024:71, Doctoral thesis, 2024)Boreal forests are evergreen landscapes that store vast amounts of carbon belowground in the form of soil organic carbon (SOC). These ecosystems act as carbon (C) sinks in their natural state as long as temperatures ... -
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 ... -
How termites and large mammalian herbivores influence tree communities, seed removal and wood decomposition in an African savanna
(PhD Thesis;2018:71, Doctoral thesis, 2018)The heterogeneity and extent savannas makes them resilient, diverse and socioeconomically important. Abiotic factors determine large-scale variation on a, but biotic factors matter at small-scales. In the African savannas, ... -
Human-mediated effects on brown bear behavior and potential cascading effects
(PhD Thesis;2018:79, Doctoral thesis, 2018)Human disturbance has been found to influence wildlife in various ways, e.g., changing their distribution in the landscape or other behavioral traits as a response to the perceived predation risk. Brown bears (Ursus arctos) ...
