(Master thesis, 2018)The Eurasian Curlew (Numenius arquata) is a species in decline, classified as near threatened (NT) worldwide, and vulnerable (VU) in Norway. In the region of Akershus (SE Norway), no recent update exists of the breeding ... -
Population monitoring of Great Crested newts in a developmental area – use of ventral side photography and automatic image recognition
(Master thesis, 2023)1. Amphibian species all over the world are in a decline due to climate change as well as human activities. To mitigate negative impacts on amphibians, especially in urban development areas, it is important to understand ... -
Post-fledging parental care in the female great grey owl (Strix nebulosa) : a trade-off between provisioning and guarding
(Master thesis, 2018)Post-fledging parental care is generally little studied in birds. By use of radio telemetry, I studied the post-fledging parental behaviour of female great grey owls (Strix nebulosa), measured as number of prey deliveries ... -
Potensielle konflikter ved havvindutbygging : en kvalitativ studie av Utsira Nord
(Master thesis, 2021)De siste årene har den landbaserte vindkraftutbyggingen i Norge økt betydelig. Imidlertid er vindkraft på land forbundet med mange konflikter som har ført til at det stadig blir vanskeligere å finne egnede og akseptable ... -
Potential energy output from horizontally inclined rooftop solar power systems in relation to electricity consumption. A case study of Sørhellinga.
(Master thesis, 2024)This thesis investigates the potential energy output of rooftop solar power systems in relation to electricity consumption. The aim was to quantify the impact a horizontally inclined rooftop solar power system could have ... -
Potential for treatment of household wastewater by using waste seashells as a biofilter media
(Master thesis, 2018)In Norway, approximately 17% of the population is served by decentralized wastewater treatment systems. In these systems, a septic tank only is used, especially in those areas where sea is the final recipient of the treated ... -
Potential Interactions of Sediment Characteristics and Oxygen Availability: Effects on Embryonic Development of Rainbow Trout (Oncorhynchus mykiss)
(Master thesis, 2024)Increasing sediment influx from construction activities threatens salmonid spawning habitats, impacting the development and hatching success of embryos due to finer sediments. This study investigates the interplay between ... -
Predicting living and dead wood volumes in a mature managed Swedish forest with airborne laser scanning
(Master thesis, 2022)Detecting dead wood with airborne laser scanning (ALS) would have many benefits. It would make it easier to find areas with high mortality rates, help make better decisions on which areas to preserve, and increase the ... -
Predicting the Extent of Root and Butt rot in Stems of Norway Spruce (Picea abies)
(Master thesis, 2020)Commercially, Norway spruce (Picea abies (L.) Karst) is the most important tree species in Norway, representing 72% of the industrial timber volume sold in 2019. However, Norway spruce is particularly prone to infection ... -
Predikering av friskkvistlengde i furu med skog- og trevariabler og data det er mulig å ekstrahere fra industriell CT-skanning
(Master thesis, 2021)Formålet med denne studien er å utvikle friskkvistmodeller som baserer seg på variabler som kan registreres ved CT-skanning av tømmerstokker. Trelast med frisk kvist har visuelle egenskaper som er attraktive i forhold til ... -
Prediksjon av bonitet i ungskog ved hjelp av laserdata
(Master thesis, 2023)I skogforvaltningen er presis bonitetsinformasjon viktig for å ta riktige beslutninger, både med hensyn til valg av tiltak og optimalt tidspunkt for gjennomføring av tiltakene. I de senere årene har flybåren laserskanning ... -
Preparerade skidspår - en fri nyttighet eller en kommersiell vara? En jämförande studie mellan Røros och Funäsfjällen
(Master thesis, 2023)I både Norge och Sverige är längdåkning en folksport och under vinterhalvåret förvandlas många destinationer till skidparadis med otaliga mil preparerade skidspår. Att underhålla och preparera skidspår är kostbart, men ... -
