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 ... -
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 ... -
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 ... -
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 ... -
Biomass estimation models and methods for miombo woodlands of Malawi using field and remotely sensed data
(PhD Thesis;2016:92, Doctoral thesis, 2016)Dry tropical forests, such as the miombo woodlands, play an important role in the global carbon budget as well as in contributing towards the sustainable development of countries such as Malawi. To ensure sustainability ... -
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 ... -
Phenology, growth and metabolism of two northern deciduous tree species in relation to temperature and light conditions
(PhD Thesis;2016:33, Doctoral thesis, 2020-11-19)In temperate climates, phenological transitions in tree species allow survival through adverse climatic conditions in winter. Seasonal change is sensed through shifting patterns in daylength, temperature and light quality. ... -
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 ... -
