Impact of climatic variation on growth of Norway spruce and European beech in South-East Norway
(Master thesis, 2015-07-03)The relationship of climate variation with growth of European beech and Norway spruce was investigated in beech-spruce forest stands in South-East Norway. In two study areas in total 81 pairs of beech and spruce trees were ... -
Impact of fertilization on field vegetation and litter layer in a boreal forest
(Master thesis, 2017)Fertilization of Norwegian boreal forests to increase carbon uptake is suggested as a measure to reduce CO2 emissions. However, studies of the effects of fertilization on field vegetation and litter layer in these forests ... -
Impact of Forest Management History on Fine Root Dynamics and Mycorrhizal Colonization in Norwegian Boreal Forests
(Master thesis, 2023)This thesis examines the influence of forest management history on fine root traits in Norwegian boreal spruce forests, focusing on the role of fine roots in carbon sequestration. The study was conducted across various ... -
Impact of frequent cutting of trees in power-line corridors on biological diversity of beetles (Coleoptera)
(Master thesis, 2012-08-06)Abstract Compared to closed-canopy forest, power-line corridors are more frequently disturbed through regular cutting of all trees. The habitat is thus maintained in an early successional stage, with much sun exposed ... -
Impact of gamma irradiation on apoptotic activity in the earthworm Eisenia fetida (Clitellata)
(Master thesis, 2015-02-27)Earthworms are organisms of key importance worldwide. As ecosystem engineers, they constitute one of the main structuring agents of most soil ecosystems. Previous studies have concluded that earthworms appear to be among ... -
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 ... -
The impact of macrophyte removal on macroinvertebrates in the river Otra, Norway
(Master thesis, 2021)Aquatic macrophytes provide complex ecosystems in the freshwaters around the world. Sometimes, macrophytes can grow to very high biomasses and restrict recreational activities in which it starts being perceived as nuisance ... -
Impacts of abiotic stress on priming of defense responses and pathogen resistance in Norway spruce
(Master thesis, 2020)Norway spruce (Picea abies) is one of the most important tree species in Norway due to its high economic and ecological significance in forests. Pathogens, fungi and insects may have detrimental impacts on Norway spruce ... -
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 ... -
Implementering av selvkjørende trucker (AGVer) på et distribusjonssenter for trelast : teknisk gjennomførbarhet og økonomisk lønnsomhet
(Master thesis, 2020)I løpet av tiårene siden 1950-tallet har selvkjørende trucker (AGVer) gradvis blitt til en vanlig del av industrimiljøet i flere næringer (detaljhandel, distribusjon og logistikk, bilindustri, flyproduksjon, helsesektor, ... -
Importance of drivers and barriers for V2G?
(Master thesis, 2021)To meet target CO2 emission reductions, there is a shift in power production, where renewable energy sources are replacing conventional power generation based on carbon dense sources like coal, gas, and nuclear. Increasing ... -
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 ... -
Improvement of the environmental situation in a school by integrating water and sanitation with school farming : a case study of schools in the districts of Chitwan and Kavre, Nepal
(Master thesis, 2018)Nepal is one of the poorest developing countries in Asia. Political tension and nature disasters has severely stunted development the last few decades. At the same time, modernization trends from the western world are ... -
Improving forest inventory and monitoring by combining remotely sensed three-dimensional and spectral information
(PhD Thesis;2011:22, Doctoral thesis, 2011)Forest inventory has benefited from remote sensing for more than 80 years. Spectral information from aerial cameras has been the dominant data source during this period. However, over the past decade the use of three-dimensional ... -
In vivo studies of respiratory physiology in Arctic charr (Salvelinus alpinus) and Atlantic cod (Gadus morhua) exposed to aquaculture relevant levels of hypoxia, hyperoxia and hypercapnia
(PhD Thesis;2010:34, Doctoral thesis, 2010)Fish in aquaculture will be exposed to water oxygen and carbon dioxide levels that they do not normally encounter in the wild. These unnatural environmental conditions may be challenging to fish as they may lack the proper ... -
Incentives, barriers and measures for increased recycling among students in student dorms : a behavioral case study on students living in selective SiÅs housings
(Master thesis, 2017)Waste sorting and recycling has become an important goal in environmental policy. As a result waste management practices has changed radically in many countries around the world. One of the major problems in the management ... -
Individual variation in movement ecology affect body mass in Svalbard reindeer
(Master thesis, 2023)Herbivore foraging is a complex interaction mainly driven by the distribution of forage in the landscape. The forage quantity and quality in the habitat influences the establishment of home ranges and diet selection from ... -
Individually characteristic corncrake Crex crex song reveals long-distance movements within the breeding season
(Master thesis, 2011-04-28)Due to modern agricultural practices, the corncrake is a species of global conservation concern. Mowing of meadows may cause corncrakes to make movements within one breeding season, but such movements are in general poorly ... -
