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 ... -
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 gypsum and açai as amendments on bauxite residue as a growth medium: chemical properties, mobility of toxic trace elements and vegetation experiment
(Master thesis, 2022)As the third most common element in the earth's crust, aluminum possesses functional qualities for a variety of industrial and household applications. The extraction of primary aluminum from bauxite ore accelerated in ... -
The effects of increased soil moisture on the timing of senescence of three plants grazed by Svalbard reindeer
(Master thesis, 2023)Climate change is affecting the Arctic faster than anywhere else on the planet, with increases in temperature and precipitation predicted to have significant effects on Arctic ecosystems. Water availability is of key ... -
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 effects on soil physical properties of long term soil tillage and soil compaction
(Master thesis, 2014-11-04)Soil degradation in crop production is becoming increasingly important because of the growing concern it poses on soil functions. Prominent among the degradation factors is soil compaction. It impairs soil productivity ... -
The environmental occurrence, fate, and behavior of airborne organic contaminants of emerging concern in Norwegian terrestrial ecosystems
(Master thesis, 2019)Airborne organic contaminants of emerging concern (AOCs) are a large assembly of organic compound groups. AOCs consist of legacy persistent organic pollutants (POPs) and new POP- like compounds. These compound groups are ... -
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 exposure of terrestrial biota to naturally occuring radiation and stable elements : case Orrefjell, a risk assessment
(Master thesis, 2018)Naturally occurring radioactive materials (NORM) can be found all over the world. Investigations of possible effects on humans and the environment have mostly focused on exploited sites like mines and their vicinity, while ... -
The fate of nitrogen in an Acrisol in Zambia under different management practices
(Master thesis, 2019)A 10-day 15N tracer experiment, using 15N-NO3 and 15N-NH4, was conducted on an Acrisol in Mkushi, Zambia, in a rain-fed maize field. The addition of the 15N label, as either 15N-NO3 or 15N-NH4, was equivalent to 0.1g/m2 ... -
