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 charcoal addition on spring wheat : a greenhouse study
(Master thesis, 2012-09-10)Abstract: In this thesis I have investigated if addition of charcoal to the soil improves the growth and yield of spring wheat. My thesis is based on an experimental greenhouse study in which different amounts of charcoal ... -
Effects of climate change on alpine plant species at Finse, Southern Norway
(Master thesis, 2012-09-07)The issue of climate change is one of the most discussed topics on Earth. The Earth is warming up and that is expected to continue in future. Alpine vegetation has already been affected by climate warming and has already ... -
Effects of climate, historical logging and spatial scales on beetles in hollow oaks
(PhD Thesis;2016:90, Doctoral thesis, 2016)Veteran trees are keystone structures and important biodiversity habitats, but they are declining on a global scale. In Europe, old oaks (Quercus spp.) are one of the most important habitat trees for biodiversity, yet the ... -
Effects of conservation farming and biochar on carbon and nitrogen cycling in light textured soils in the sub-humid tropics
(PhD thesis;2019:41, Doctoral thesis, 2019) -
Effects of conversion of natural forest to plantations, traditional agroforestry and cultivated lands on carbon sequestration and maintenance of soil quality in Gambo district, Southern Ethiopia
(PhD Thesis;2009:40, Doctoral thesis, 2009)Clearing and conversion of natural forest to short rotation plantation, traditional agroforestry, crop and grazing land uses are rampant in Ethiopia. The unabated deforestation and the eventual reduction in soil productivity ... -
Effects of culling on the pelagic whitefish population in Lake Randsfjorden aiming at establishing a commercial fishery
(Master thesis, 2015-08-05)The fishery in Lake Randsfjorden has long traditions, and especially the European whitefish Coregonus lavaretus has earlier played an important role as additional food supply for local communities in the area. After a rapid ... -
Effects of disturbance on biological diversity of beetles (Coleoptera) in the field layer: a comparison between power-line corridors and closed-canopy forests.
(Master thesis, 2012-09-07)Since the start of industrial forestry in the 1700 century Norwegian boreal forests have gone true a dramatic change. Modern forestry practices have made the forests more homogenous, due to clear cutting of old forest, ... -
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 fire history on species richness and carbon stocks in a Peruvian puna grassland, and development of allometric equations for biomass estimation of common puna species
(Master thesis, 2011-09-09)High-elevation ecosystems have recently received increasing attention from the carbon financing sector. This has sparked the need for reliable and non-destructive methods to estimate carbon stocks in these ecosystems. The ... -
Effects of forest fire on production of down woody debris in Aust-Agder County in Norway
(Master thesis, 2011-10-07)Forest fires have played an important role in structuring the boreal conifer forest. Forest fires produce dead wood, which is important for biodiversity. Many species, including Red List species, are dependent on dead wood ... -
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 forestry, predators and weather on capercaillie (Tetrao urogallus) and black grouse (Lyrurus tetrix) in South-East Norway
(Master thesis, 2017)The European populations of capercaillie (Tetrao urogallus) and black grouse (Lyrurus tetrix) have declined the last 50 to 100 years. The decline has happened at the same time as changes in forestry practices, predation ... -
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 hunting on primate populations in Pacaya-Samiria National Reserve, Peru
(Master thesis, 2017)De viktigste makrohabitatene av skog som finnes i Amasonas bassenget er terra firme skoger som ikke blir oversvømt og sesongmessig oversvømte várzea skoger. Disse skogene huser ulike ansamlinger av flora og fauna, som ... -
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 ... -
