Effect of Conservation Agriculture and Biochar on Soil Hydraulic Properties in a Ugandan Plinthosol
(Master thesis, 2023)Conservation agriculture (CA) is regarded as a robust and resilient agricultural practice, able to meet the challenges related to climate change. Conservation farming in combination with biochar (BC) has gained increased ... -
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 grazing in Norwegian outfields related to the quantity and quality of soil organic carbon and other soil properties
(Master thesis, 2022)Utilization of the outfield for grazing have long traditions in Norway. Not only as a pasture, but also mowed to provide food for the winter (Rekdal & Angeloff, 2021). From 1949 to 1999, grazing in Norway changed from ... -
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 salmon lice (Lepeophtheirus salmonis) infestations on the behaviour of prematurely returned sea trout (Salmo trutta) in the Hardangerfjord
(Master thesis, 2022)The expansion of the salmon farming industry along the Northern coasts has caused a higher concentration of salmon lice (Lepeophtheirus salmonis) in the coastal waters and fjords. There has been observed that Sea trout ... -
Effect of Season and Habitat on Two Congeneric Bat Species in a Fragmented Forest Landscape, Central Amazon, Brazil
(Master thesis, 2022)Bats are an important component of Amazonian mammal communities but are often ignored during conventional biodiversity assessments. Much is therefore unknown regarding spatial and temporal forest use and the partitioning ... -
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
