Pollination Efficiency of Native Bees and Honeybees to Apple in Norway
(Master thesis, 2023)Crop pollination is traditionally managed with the European honeybee (Apis mellifera). However, the supply of honeybees may not be sufficient to meet the increasing global pollination demands and beekeepers are met with ... -
Population estimate, trend and habitat preferences of breeding curlews (Numenius arquata) in Akershus, southeast Norway
(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 ... -
Post-fledging parental care in the great grey owl (Strix nebulosa) : female contribution and fledgling movement
(Master thesis, 2019)In owls and birds of prey male and female have distinctive roles in parental care. Our knowledge about these roles mostly concerns the pre-fledging period, because in the post-fledging period fledglings move about and are ... -

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 avoidance and barrier effects of a power line on range use and migration patterns of semi-domestic reindeer (rangifer tarandus tarandus)
(Master thesis, 2011-10-07)Infrastructure like roads and power lines may be a disturbance to, or be perceived as a barrier, for reindeer (Rangifer tarandus tarandus). Possible avoidance and barrier effects, in addition to reindeer habitat selection ... -
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 of rainwater harvesting in Nepal : a case study
(Master thesis, 2016-08-11)This paper gives an overview of RWHS in urban Kathmandu valley (27°32’13”- 27°49’10” N 85°11’31” & 85°31’38” E). The rainwater collection is during monsoon season (June-August) and some amount of water can be collected by ... -
Potential of rainwater harvesting in Nepal : a case study of kathmandu
(Master thesis, 2017-08-15)This paper gives an overview of rainwater harvesting system in urban Kathmandu valley (27°32’13”- 27°49’10” N 85°11’31” & 85°31’38”E) that can be harvested during monsoon season (June-August) and use of collected rainwater ... -
Power line clearings : suitable habitat for semi-natural grassland species?
(Master thesis, 2016-08-09)Owing to land-use changes, abandoning and intensification of agriculture, semi-natural grasslands are becoming increasingly scarce all over Europe. As a consequence many of the species associated with these habitats have ... -
Power line strips provide nest sites and floral resources for cavity nesting bees
(Master thesis, 2014-09-12)English A review by Cadotte et al. (2011) argue for the importance of using a functional diversity approach in conservation of ecosystem processes. In this study I focused on the functional group of cavity nesting bees, ... -
Praktisk implementring av PEFC- og FSC-sertifikatene

Predation on artificial nests in relation to human activity and willow ptarmigan density along landscape gradients in a boreal ecosystem
(Master thesis, 2010-12-16)Sammendrag I et forsøk gjennomført i fem lirypeområder i Midt-Norge fant vi at totale predasjonsrater på falske reir med vaktelegg (Coturnix coturnix) varierte fra 39.8 % til 50.7 % over tre år. De vanligste eggpredatorene ... -
Predation-induced ungulate carcasses mediate vegetation composition in the boreal ecosystem
(Master thesis, 2017)Apex carnivores are mostly recognized for their effects on ecosystem processes through altering population dynamics and behaviour of their prey. Apex carnivores may also affect lower trophic levels through the distribution ... -
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 ... -
