Equilibrium factor of radon progenies in Norwegian homes
(Master thesis, 2021)Several hundred deaths each year are caused by radon-induced lung cancer in Norway. Lung cancers are mainly caused by the inhalation of radon and alpha radiation from the airborne short-lived radon or progenies but not by ... -
Er det lønnsomt å produsere hydrogen fra solenergi til tungtransportformål i Norge?
(Master thesis, 2017)Large volumes of Norway's greenhouse gas emissions are associated with road transport, of which about one third of the emissions come from the heavy transport sector. The problem is that the heavy transport sector has such ... -
Er det størrelsen det kommer an på? : en studie om vern av økologiske funksjonsområder som verktøy for bevaring av biologisk mangfold
(Master thesis, 2014-02-13)I den senere tid er det satt økt fokus på og vokst frem en bredere forståelse for at samspillet i naturen er svært komplisert. Økosystemtilnærmingen er kommet på banen. Erkjennelse av at det er viktig å ta vare på det ... -
Er skogkartlegging med flybåren laser en mer hensiktsmessig måte for å finne områder med naturskog, enn Natur i Norge (NiN)'s naturskogkriterier? : en gjennomgang av to metoder for å skille gammel plukkhogd skog fra gammel flatehogd skog
(Master thesis, 2019)Skogen i Norge har ulike naturgitte forutsetninger på regional skala, hvor klima, vekstforhold og skogbrukshistorie påvirker det biologiske mangfoldet. Fragmentering av skogområder, langtransportert forurensning, skogbruk, ... -
Er vegetasjon og insektsamfunnet forskjellig rundt gamle og unge eiker? : en sammenligning av vegetasjon, biller og veps rundt gamle og unge eiker i Vestfold og Telemark, Norge
(Master thesis, 2019)Store, grove eiketrær er viktige habitat for veldig mange forskjellige arter, fra fugler til insekter. Nedgang i antall eiker har ført til at artene som har spesialisert seg på eiker har blitt mindre vanlige, noen til og ... -
Erfaringer, lønnsomhet og muligheter knyttet til bruk av fornybar energi til korntørking
(Master thesis, 2023)Tørking av korn er en energikrevende prosess som krever høy effekt i en kort periode. Korntørking på gårdsnivå i Norge baserer seg i stor grad på bruk av fossil energi. For at landbruket skal klare å innfri sine mål om ... -
Erioderma pedicellatum : an ecophysiological study of a globally threatened pioneer lichen on thin spruce branches in old forests
(Master thesis, 2021)Lichen extinction occurs at a fast rate due to human activity, and species yet to be discovered are likely go extinct every year. Many species close to extinction may still be rescued by conservation management based on ... -
Espedal-sjøfasen under siste isavsmelting
(Master thesis, 2020)I denne oppgaven er det brukt LiDAR data og georadarundersøkelse til å få innblikk i utviklingen i nordlige Espedalen under siste isavsmelting. Dette er gjort ved undersøkelse av to deltaavsetninger ved innsjøene Olstappen ... -
Establishing a biodiverse meadow roof in Oslo, Norway : an evaluation of the effect of soil type and soil depth on sown native and local species and spontaneously colonizing species
(Master thesis, 2020)The loss of biodiversity is happening faster now than ever in human history, being mainly driven by changes in land use. Concurrently, cities are expanding and are expected to reach over 1.2 million km2 within 2030. The ... -
Establishment, survival and dispersal limitations of pioneer plants in a Norwegian glacier foreland as revealed by seed sowing, transplantation and seed bank experiments
(Master thesis, 2016-09-02)Glaciers are melting and retreating on a global scale due to climate change. Rapid glacier retreat leave behind large areas of barren ground, in which primary succession and plant establishments can start. However, a typical ... -
Estimates of wolf density, abundance, and population dynamics in Scandinavia, 2012 - 2021
(MINA fagrapport;72, Report, 2021)Background The Scandinavian wolf (Canis lupus) population is being monitored annually using non-invasive genetic sampling (NGS) and recovery of dead individuals. DNA extracted from faeces, urine, hair, and tissue is used ... -
Estimating and analysing the occupancy of the introduced shrew Crocidura russula in Norway
(Master thesis, 2021)The Greater white-toothed shrew (Crocidura russula) is a shrew that was discovered in Norway in 2017. The species is of concern because it is invasive and has a history of environmental impact. It is native around the ... -
Estimating densities of red foxes using non-invasive genetic sampling and spatial capture-recapture modeling
(Master thesis, 2020)Spatial capture-recapture modelling (SCR) is a powerful tool for estimating densities, population size and space use of elusive animals. However, SCR modeling has not been widely applied to ecologically important mesopredators ... -
Estimating global demand for coniferous sawnwood taking uncertain variables into account
(Master thesis, 2019)This thesis aims at providing new estimates regarding the global demand for coniferous sawnwood. Individual and representative elasticities of demand for the sample of 92 countries that represented 97 % of the global ... -
Estimating the size of the Scandinavian wolf population with spatial capture-recapture and conversion factors
(MINA fagrapport;57, Report, 2019)Monitoring of wolves (Canis lupus) in Scandinavia is a coordinated effort between Swedish and Norwegian management authorities. Since 2012/13, the size of the Scandinavian wolf population is being estimated indirectly by ... -
