Testing host choice of Ips typographus in Norway spruce and two North American spruce species, using field studies and lab analysis
(Master thesis, 2019)The spruce bark beetle Ips typographus is one of the most damaging pests in Europe’s boreal forests and cause catastrophic tree mortality during outbreaks. Norway spruce (Picea abies), an economically important forest tree, ... -
Testing og videreutvikling av et GISbasert verktøy for terrengtransport planlegging
(Master thesis, 2016-08-31)Det norske skogbruket har hatt en rivende utvikling siden 50-tallet med tanke på utstyr til hogst og tømmertransport. Etter dette har det blitt forsøkt og forenkle planleggingsprosessen av hogster og tiltak med tanke på ... -
The combined effect of depleted uranium, sodium arsenite and gamma radiation on survival, growth and reproduction of Caenorhabditis Elegans
(Master thesis, 2017-03-31)The purpose of this work was to study the effect of depleted uranium, sodium arsenite and gamma radiation on three biological endpoints of Caenorhabditis Elegans. The three endpoints studied were survival, growth, and ... -
The cushion plant Silene acaulis : biotic interactions along an environmental gradient at alpine Finse, southern Norway
(Master thesis, 2013-07-24)Plants interact with each other in many ways. Competition for resources and space is well documented among a wide variety of plants. Positive interactions, or facilitation, may also be important for plant survival, ... -
The decline of moose (Alces alces) fitness : a result of poor browse availability and high browsing pressure? - A comparative study of two Norwegian Moose ranges
(Master thesis, 2013-08-26)There has been a recorded difference in carcass weights among moose (Alces alces) on the western side of the Oslo fjord compared to the eastern side over the last decades. So far, this reduction has been credited to ... -
The Diversity and Behavior of Pollinating Insects in Apple Orchard
(Master thesis, 2023)Diverse assemblages of insects improve the overall productivity and stability of natural and agricultural ecosystems. Cultivated fruit crops, such as apples, that require pollination services by insects are particularly ... -
The effect of a wind farm on native vegetation and area use of three cervid species : a case study into the planning and ecological effects of constructing a wind power plant in Southern Norway
(Master thesis, 2016)Wind energy is increasingly popular globally, with numerous wind farms also being planned and constructed in Norway. Wind production is considered to have a low impact on the environment, yet research on local ecological ... -
The effect of biochar in combination with mineral or organic fertilizers on crop production in Nepal
(PhD Thesis;2018:23, Doctoral thesis, 2018)The majority of poor people in Nepal relies on agriculture for employment and livelihood sustenance. Declining soil fertility and ongoing climate change are the key challenges faced by farmers, with adverse effects on crop ... -
The effect of distance from forest edge on flower visitor frequency and fruit set : a case study of Cucumis sativa around Kakamega forest
(Master thesis, 2018)Pollination is a key ecosystem function that is important for food production. This service is maintained by natural habitats which provide a dwelling place for these pollinators. However, these natural habitats are on the ... -
The effect of experimental warming on insect herbivory in an alpine plant community
(Master thesis, 2013-08-23)Climate warming is predicted to affect species and trophic interactions worldwide, and alpine ecosystems are expected to be especially sensitive to changes. There are few studies on how insect herbivory respond to warming. ... -
The effect of freezing and thawing on transport of pesticides through macroporous soils and the potential risk towards the aquatic environment
(Master thesis, 2017)Pesticides and their metabolites can leach rapidly through agricultural soils through macropores, be transported further into surface waters and potentially cause negative effects in aquatic organisms. Cold climate with ... -
The effect of ground icing events on Svalbard reindeer (Rangifer tarandus platyrhynchus) space use and habitat selection
(Master thesis, 2012-09-14)Den arktiske vinteren er preget av ustabile værforhold der temperaturen kan øke til over frysepunktet. Disse mildværsperiodene fører til endrede egenskaper til snødekket og nedbør faller som regn på snø (rain on snow, ROS). ... -
The effect of long-term experimental warming on lichens and vascular plants in an alpine Dryas heath
(Master thesis, 2018)Global warming affects species diversity and ecosystems throughout the world, and alpine and arctic plant communities are considered to be particularly sensitive. During the last decades, several studies have shown a shift ... -
The effect of proximity to forest on bee visit frequency to six plant species in an oil palm landscape in Borneo
(Master thesis, 2018)Pollination is critical for global food security as it ensures the reproduction of many wild and crop plants. Pollination services may be at risk as tropical rainforests are rapidly being destroyed and degraded, largely ... -
The effect of Red Deer browsing pressure on the subsequent selection of bilberry plants by Red Deer and Lepidoptera Larvae
(Master thesis, 2015-08-10)Browsing by deer may induce defence in plants which may subsequent affect food quality for herbivores. Lepidoptera larvae are thought to be more sensitive to defence substances in plants than larger herbivores, like red ... -
The effect of secondary metabolites, nutrients and invertebrates on fungal establishment and decomposition rates in European Aspen (Populus tremula)
(Master thesis, 2019)Fungal decomposer communities play an essential role in nutrient cycling and are one of the main drivers of decomposition. Although fungal community composition has been seen to influence the rate of wood decay, little is ... -
The effect of selective logging on the community of chewing lice and feather mites associated birds in Sabah, Malaysia
(Master thesis, 2016-09-02)Selective logging is degrading tropical rainforests worldwide at high rates altering its microclimate and structure. Hence, changes in the assemblages of some taxa have been recorded after selective logging. This is the ... -
