Lichen-gastropod interactions : Chemical defence and ecological consequences of lichenivory
(PhD Thesis;2010:2, Doctoral thesis, 2010)Herbivory are considered a significant factor regulating plant communities. Some mammals, e.g. reindeers, substantially influence lichen-dominated communities. The impact on lichens posed by invertebrate grazers is less ... -
Life cycle assessment of mountain forest wood fuel supply chains : case studies from Norway and Italy
(PhD Thesis;2011:57, Doctoral thesis, 2011)Concerns about the fast growth in greenhouse gas emissions have encouraged several countries to increase their use of renewable energy. According to the EU’s Renewable Energy Directive (RED), 20% of all the energy production ... -
Liquid water absorption in wood cladding boards and log sections with and without surface treatment
(PhD Thesis;2010:6, Doctoral thesis, 2010)Water absorption in wood in service is of great importance both because of the resulting dimensional changes of the wood and because of the risk of deterioration by microorganisms at wood moisture content levels above 20 ... -
Local and systemic defence responses in trees against pathogenic fungi : differences revealed at the transcriptional level
(PhD Thesis;2011:43, Doctoral thesis, 2011)Forest trees dominate the earth surface and has special place in the economy and ecology of the planet. Due to the long life span of woody trees they are challenged by the abiotic and biotic factors. Over the long history ... -
Modeling hourly energy consumption in Norwegian buildings
(PhD Thesis;2016:91, Doctoral thesis, 2016)Growing world population, unabated use of fossil fuels, and economies aiming at continuous growth exhaust the planet’s natural resources and add to an augmented greenhouse effect. Besides limiting population growth in less ... -
