Effect of seed treatment with putative defence priming chemicals on defence-related gene expression and pathogen resistance in Norway spruce (Picea abies) seedlings
(Master thesis, 2020)Chemical seed treatment may be a simple method to protect conifer seedlings from pests and pathogens in plant nurseries and forest stands. In this study, I tested the ability of eight putative defence priming chemicals ... -
The effect of Silene acaulis on soil bacterial communities across elevational and latitudinal gradients in Scandinavia
(Master thesis, 2022)Microbes are ubiquitous, extremely diverse, and contribute to important ecosystem functions. Soil bacterial communities, in particular, play an important role in carbon and nutrient cycling, through decomposition and carbon ... -
The effect of tunnel construction particles on Daphnia magna
(Master thesis, 2022)Particles originating from drilling and blasting during tunnel construction have the potential to end up in the environment, however, there is a knowledge gap concerning the effect of these particles on aquatic biota. In ... -
Effects from environmental factors and individual characters on activity and depth use in a Northern pike (Esox lucius) population subjected to recreational fishing : an acoustic telemetry study
(Master thesis, 2018)Northern pike (Esox lucius) is a common top- predator in freshwater systems all over the Northern Hemisphere. For centuries it has been a popular target for recreational anglers. In many freshwater ecosystems, recreational ... -
Effects of biochar and crop rotation with pigeon pea on soil phosphorus availability in Mkushi and Kaom, Zambia
(Master thesis, 2022)Low phosphorus (P) availability in sub-Sahara African agriculture strongly effects yield and food production negatively. As fertilizer prices increases, the need for human interventions to increase soil plant available P ... -
The effects of biochar on immobilizing Pb, Zn, Cu and Cd in contaminated soils from the mining sites in Kabwe (Zambia) and Folldal (Norway)
(Master thesis, 2021)Mining activities and resulting waste products are among the main sources of severe heavy metal pollution in the world. This study aims to examine i) the level of soil contamination, ii) mobility and ii) bioavailability ... -
Effects of boreal forest fertilization on carbon storage and ectomycorrhizal fungi
(Master thesis, 2020)Boreal forests represent a large fraction of the global carbon (C) stock. Increasing attention is given to utilizing these forests in the battle against climate changed driven by increased atmospheric CO2. Part of this ... -
Effects of electrochemical treatment of mixed liquor in submerged ceramic membrane bioreactor
(Master thesis, 2019)Our most valuable and irreplaceable resource is water. Humanity withdraws 3.928 km3 of freshwater per year. Approximately 44% is used for agricultural purposes, the other 56% discharged as wastewater (WW). A large amount ... -
Effects of elevation on the lichen community palatability in an alpine ecosystem
(Master thesis, 2021)Lichens are present in almost all terrestrial ecosystems, and in some of them, they are the main primary producers. Most studies focus on vascular plant communities, even studies on ecosystems where lichens represent an ... -
Effects of forest management history on fine roots and mycorrhizal colonization in Norwegian boreal spruce forests
(Master thesis, 2023)Fine roots play critical roles in carbon cycling in boreal forests. However, they are poorly represented in the studies of forest management effects on forest soil, likely due to the labour- intensive methods of soil ... -
Effects of fork length on the utilization distribution and habitat preferences of anadromous Arctic charr (Salvelinus alpinus) in a sub-arctic lake
(Master thesis, 2021)This was an acoustic telemetry study investigating lacustrine habitat utilization of anadromous population of Arctic charr (Salvelinus alpinus) located in Storvatnet in Hammerfest multiplicity northern Norway. Arctic charr’s ... -
Effects of gut microbiota composition on vitellogenin expression in honeybees
(Master thesis, 2020)The relationship between animals and their gut microbiota is one of the most important symbiotic relationships in nature. The western honeybee, Apis mellifera, has received particular attention in microbiota research because ... -
Effects of long-term experimental warming on alpine bryophytes : trends in functional traits
(Master thesis, 2019)Functional traits are becoming increasingly important tools to evaluate plant community response to climate change. Artificial warming treatments can shift community-level trait values as a consequence of intraspecific ... -
Effects of long-term experimental warming on fitness, morphology and species interactions of Silene acaulis
(Master thesis, 2020)The global annual average surface temperature has increased significantly during the past century and is predicted to continue rising. Studies have shown that alpine ecosystems can be particularly sensitive to climate ... -
Effects of macrophyte removal on habitat use of brown trout (Salmo trutta)
(Master thesis, 2021)Aquatic macrophytes play an important role in freshwater ecosystems. They are primary producers, promote good water quality, and provide food and habitats for various organisms, including fish. When macrophytes have ... -
EFFECTS OF MICROBIOME ON CONIFER HEALTH AND RESISTANCE TO BIOTIC AND ABIOTIC STRESS: A SYSTEMATIC REVIEW
(Master thesis, 2023)ABSTRACT The dynamics of plant-microbiome interactions under different stress conditions are important to understand in order to elucidate the mechanisms underlying forest decline and tree mortality. This study aims to ... -
Effects of plant-plant interactions on the performance and abundance of Campanula uniflora in Dovre, Norway
(Master thesis, 2021)Anthropogenic environmental changes cause direct and indirect negative effects on alpine ecosystems. Human activities are accelerating the greenhouse effect and fragmenting and changing habitats. Increased temperature has ... -
Effects of plastic additives on precision cut liver slices (PCLS) from Atlantic cod (Gadus morhua)
(Master thesis, 2019)A vast amount of the plastic we use end up in the ocean and estimates suggest a doubling of plastic in the ocean, to 250 million tonnes by 2025. Plastic contain additives such as phthalates, and these are known to have ... -
The effects of precipitation on parental food provisioning in the barn owls (Tyto alba) breeding in Norfolk, UK
(Master thesis, 2021)Even though scientists have extensively studied the barn owl (Tyto alba), there is limited information on how climatic conditions influence parental food provisioning in barn owls on a local scale. Worsened climatic ... -
Effects of repeated captures on Svalbard reindeer (Rangifer tarandus platyrhyunchus) : implications for animal welfare and scientific bias
(Master thesis, 2021)Capturing and marking animals is an essential component of wildlife research. However, data gathered using invasive methods may lead to scientific bias and compromise animal welfare. It is therefore important to evaluate ...
