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 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 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 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 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 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 ... -
The effect of sheep (Ovis aries) on the abundance of ticks (Ixodes ricinus) on the West coast of Norway
(Master thesis, 2012-08-06)The prevalence of ticks is increasing in many parts of the world, including Norway. There are uncertainties why this is happening, but the suggested main three drivers are climate, encroachment and increased abundance of ... -
The effect of ticks (Ixodes ricinus) on early survival of roe deer (Capreolus capreolus) fawns
(Master thesis, 2017)Parasites can be a burden for many animals and may in some cases affect the survival and reproduction of their hosts. The effect ticks may have on the early survival of roe deer (Capreolus capreolus) fawns is less known. ... -
The Effects of Red Deer (Cervus elaphus) herbivory and forestry on bilberry (Vaccinium myrtillus) and on regeneration of understory trees
(Master thesis, 2015-07-03)Herbivory and forestry activities are two drivers that affect forest vegetation structure. Increased cervid populations is a cause of concern as they have a substantial impact on vegetation structure. In addition, forestry ... -
The effects of UV radiation on the content of phenolic acid and flavonoid, stomatal conductance and taste in red lettuce 'Lollo Rosso'
(Master thesis, 2016-08-31)The use of supplementary light to improve the quality of red lettuce is common practice in today’s greenhouse production. Fluorescent lamps that emit Ultraviolet (UV) radiation have been shown to increase the synthesis of ... -
The expansion of red foxes (Vulpes vulpes) into alpine areas - Effects of human-induced subsidies along roads, and consequences for ground-nesting birds
(Master thesis, 2016-08-15)During the past century, the red fox (Vulpes vulpes) has gradually increased its presence in alpine habitats, threatening endangered species such as the arctic fox (Vulpes lagopus). Several factors have been suggested ... -
The fffects of changes in livestock grazing and agricultural land use on an endangered orchid, Herminium monorchis, in Norway : a correlative and experimental approach
(Master thesis, 2016-08-31)Changes in agricultural practices and land use, with abandonment of low-intensity grazing and the transformation of semi-natural meadows into cultivated agricultural areas, have shown negative impacts on several plant ... -
The forest Carbon Certification Project in Iceland : a case study
(Master thesis, 2011-11-11)This study is a part of a bigger project aimed to develop a certification system for carbon stock changes due to afforestation in Iceland. This is interesting because carbon credits created by removals of CO2 from the ... -
The fungal factor : male spider mites prefer fungally killed females to healthy live ones
(Master thesis, 2016-07-27)The two-spotted spider mite, Tetranychus urticae, is a serious pest in a wide variety of crops worldwide, and can negatively affect the production of strawberries. Males of T. urticae approach and guard quiescent deutonymph ... -
The future importance of short term markets: An analyse of intraday prices in the Nordic intraday market; Elbas
(Master thesis, 2017-05-15)The intraday market allows market participants to trade energy nearer to the period of delivery, and will play an essential role in enabling the expected increase of renewable energy in the European energy mix. This thesis ... -
