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 ... -
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 ... -
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) ... -
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 ... -
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 ... -
Impediments to forest recovery in bracken-dominated clearings in the African Highlands
(PhD Thesis;2018:70, Doctoral thesis, 2018)Vegetation dynamics in disturbed forested landscapes remain incompletely understood. Considerable areas with stalled forest recovery occur worldwide and may reflect the effects of dense and persistent understorey plants ... -
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 ... -
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 ... -
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 ... -
Large carnivore responses to human activity and infrastructure at multiple scales in Scandinavia

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 ... -
Late Weichselian glacial dynamics and retreat patterns of the Fennoscandian Ice Sheet in Gausdal Vestfjell, southcentral Norway, acquired from spatial data
(PhD thesis;2018:68, Doctoral thesis, 2018)Evidence-based geomorphological research (analyses of glacial landform record) is one of the commonly used types of glacial reconstructions applied for studying the past ice sheets. The work covered by this thesis contains ... -
Leveraging non-invasive monitoring of carnivores using hierarchical models
(PhD thesis;2020:59, Doctoral thesis, 2020)The development of non-invasive approaches for monitoring wildlife populations made it feasible to obtain ecological parameters across landscapes and populations, rather than a few locations or individuals. The two most ... -
LiDAR, habitat structure and the ecology of ungulates in a landscape of fear
(PhD Thesis;2015:5, Doctoral thesis, 2020-11-10)The expression ‘landscape of fear’ describes a situation in which prey behavior and space use across the landscape are shaped by spatial and temporal patterns in predation risk. Yet such behavioral and indirect effects of ...
