(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 ... -
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. ... -
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 ... -
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 ... -

(PhD Thesis;2019:105, Doctoral thesis, 2019)With the rise of modern wind turbines, wind energy has grown to become a major source of generated electricity, alongside other renewable and conventional energy sources. The geographical and time dependent nature of wind ... -
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 ... -
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 ... -
