16 years of river restoration : effects of restoration measures on macroinvertebrates and salmonids in Bognelv, Northern Norway
(Master thesis, 2022)Lotic ecosystems worldwide are being degraded by human activities, with severe consequences for stream biota. River restoration has gained momentum over the last decade, but many projects lack the long-term monitoring ... -
Acid mine drainage from Folldal mine tailings : geochemical characterization and simulation
(Master thesis, 2018)The mining of certain minerals, such as copper and zinc is commonly connected with acid mine drainage (AMD) problems that can have serious impact on human health and cause ecological destruction. The Folldal mining area ... -
Activated and enriched “designer” biochar as sorbent in remediation of PFAS and metal contaminated soils
(Master thesis, 2019)Soil contamination has become a major environmental problem of global concern, and there is a need for effective remediation methods to counteract this problem. Immobilisation of contaminants in soil using the carbonaceous ... -
Aggregatstabilitet i jord med ulike nivåer av plantetilgjengelig fosfor
(Master thesis, 2021)Aggregatstabilitet brukes som et mål for å vurdere en jords strukturelle kvalitet. Det er viktig å opprettholde høy aggregatstabilitet for å bevare jordens produktivitet, minimere jorderosjon og miljøforurensing som følge ... -
Akkumulering av metaller i en innsjø eksponert for avrenning fra høytrafikkert veg, landbruk, kommunalt avløpsnett og tette flater : vertikal fordeling av metaller i en sedimentsøyle fra Østensjøvannet, Ås kommune
(Master thesis, 2020)Avrenning fra vegnettet kan være en viktig kilde til diffus forurensning, og kan inneholde flere metaller fra ulike vegtrafikkrelaterte kilder. Metaller er av spesiell interesse i tilknytning til vegavrenning grunnet deres ... -
Alunskifer : bergarters svarte får : en redegjørelse for forurensningspotensialet til alunskifer, med særlig fokus på uran
(Master thesis, 2018)It has been acknowledged for a long time, that alum shale is a rock that causes trouble. Already in 1957, reports said that the rock caused technical problems, because it started to swell beneath buildings. An even greater ... -
An evaluation of the efficiency of survey methods to monitor large mammals in Cusuco National Park, Honduras
(Master thesis, 2017)Field sign surveys and camera trap surveys are frequently used in the tropics as the preferred survey technique to monitor large terrestrial mammal communities. However, these methods vary in the efficiency of detecting ... -
Analyse av residuallast og fleksibilitetsbehov i Nord-Europa i 2040
(Master thesis, 2019)Målsetningen med studien var å kvantifisere fleksibilitetsbehovet i Nord-Europe for ulike scenarier i 2040, og undersøke hvor mye at dette behovet som kan dekkes av mer overføringskapasitet mellom landene. Studien tar ... -
Analysing forests naturalness in southern Norway using airborne laser scanning
(Master thesis, 2021)Biological and ecological important areas and species are in increasing focus now. Earlier protected areas have mostly excluded productive forest areas in Norway. The added focus on these areas combined with an increased ... -
Anrikning og omsetning av metaller i innsjøer utsatt for veiavrenning, studert med paleolimnologiske metoder
(Master thesis, 2018)Ved hjelp av paleolimnologiske metoder kan man undersøke metallkonsentrasjonene for de ulike lag i en sedimentsøyle og hvordan konsentrasjonene har endret seg over tid. En uforstyrret sedimentsøyle som går langt tilbake i ... -
Antioxidant enzyme system in fish from contaminated lakes in Chernobyl exclusion zone
(Master thesis, 2020)Akvatiske organismer i Tsjernobyl-eksklusjonssonen har blitt kronisk eksponert for ioniserende stråling siden atomkraftulykken i Tsjernobyl i 1986. Fisk anses som de mest radiosensitive akvatiske organismene, og i den høyt ... -
Application of Aerogel-based plaster for refurbishment and preservation of a listed historic masonry building in Norway : an in-situ energy efficiency study
(Master thesis, 2018)This thesis examines the energy efficiency effects of refurbishing historic masonry buildings in a Norwegian climate with the use of an aerogel-based plaster (FIXIT222) for cold side insulation. Additionally, it aims to ... -
Application of waterborne electrical resistivity tomography and ground penetrating radar in the delta area of Numedalslågen, Norway
(Master thesis, 2018)Two non-invasive geophysical methods have been tested in the lowermost reaches of the river Numedalslågen, Southern Norway. The aim were to estimate thickness of sediments, possible layering and the depth to the bedrock. ... -
Area uses and general habitat preferences of ospreys
(Master thesis, 2021)The area uses and general habitat preferences of ten ospreys from south-eastern Norway were studied in their home ranges, wintering areas, and during their migrations. The ospreys were tracked using GPS transmitters and ... -
Arthropod succession following a mass mortality event of reindeer (Rangifer tarandus) in an Alpine ecosystem
(Master thesis, 2020)Carcasses are of great ecological importance, especially as a resource for arthropods. However, many aspects of carrion ecology remain to be investigated. One of these aspects is the ecological significance of mass mortality ... -
Assessing the effect of environmental variables on microhabitat selection and distribution for seven amphibian species in Colombia using in-situ and MaxEnt approaches
