The effect of artificial light and latitude on foraging activity in resident passerines in Northern Europe
(Master thesis, 2020)Over the last couple of decades, there has been an increasing interest in the ecological consequences of artificial light on wildlife. At northern latitudes, winter is characterized by short days and low temperatures, ... -
Effect of Elevation Differences in Alpine Insect Activity on Silene Acaulis at Finse, Norway
(Master thesis, 2021)Global annual average temperature has increased since the industrial revolution and is predicted to continue to increase in the future resulting in altered species distributions. Alpine ecosystems are particularly vulnerable ... -
Effect of farmland type and vegetation height on habitat use and breeding success of northern lapwings in south-east Norway
(Master thesis, 2020)Habitat use is a key element to understanding how endangered species should be protected from further decline. The northern lapwing (Vanellus vanellus) is a red-listed farmland species threatened by multiple factors such ... -
Effect of macrophyte removal on CO2 emissions in the river Otra, Norway
(Master thesis, 2021)The main goal of this study is to examine how macrophyte removal affects CO2 emissions in rivers with a secondary aim of quantifying CO2 concentrations and emissions in the river over the course of 24 hours. The study was ... -
Effect of nanoplastics in the marine organism Tisbe battagliai
(Master thesis, 2019)Plastic is a material made out of polymer chains derived from oil and gas, and together with additives these polymers have numerous applications. Plastic is used in daily life as wrapping around food, in cosmetics and in ... -
Effect of nitrogen fertilization on decomposition in boreal forest
(Master thesis, 2021)Anthropogenic activities have resulted in escalating deposition of nitrogen in many forms that impact several aspects of ecosystem especially lying on boreal region where N is a limiting factor for tree growth. Although N ... -
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 ... -
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 ... -
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 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 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
