Partial migration as a response to ground icing events in a high arctic ungulate
(Master thesis, 2014-08-19)Partial migration – a phenomenon where only part of a population performs annual migrations, is common in ungulates. Despite partial migration being well documented, little is known about the annual partial migration ... -
Partitioning of prey for nestlings by female Eurasian kestrels (Falco tinnunculus). Effect of prey type, prey size and brood size.
(Master thesis, 2011-04-28)I used the video recordings from 19 nests of the Eurasian kestrel (Falco tinnunculus) located in south-eastern Norway to investigate allocation of food from parents to nestlings. Prey was both avian and mammalian. The mass ... -
Performance Assesment of a Solar PV-Grid Connected Installation in Ås, Norway
(Master thesis, 2014)The Norwegian government is committed to increase the renewable energy share of the Norwegian primary energy consumption to 67.5%, and to increase the share of energy in transport to 10% renewable by 2020. In order to ... -
Plant Response to Biochar Augmented Soils from Different Biogeographic Regions
(Master thesis, 2012-11-14)The objective of this study is to use plant phytometers to test whether biochar amendment increases soil fertility. The phytometric method has the asset of measuring the actual effect of biochar ... -
Plantekvalitet og etableringsevne hos toårige planter av gran (Picea abies)
(Master thesis, 2017)Foryngelse er det første og viktigste steget etter hogst for å sikre bærekraftig bruk og utnyttelse av skogressursene. Gran (Picea abies) utgjør omtrent halvparten av stående volum i norsk skog og forynges i hovedsak gjennom ... -

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 ... -
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
(Master thesis, 2017)På 73,5 % av det produktive skogarealet i Norge kan det drives konvensjonelt skogbruk og her er hensyn til biologisk mangfold og naturtyper ivaretatt av skogloven og skogsertifisering. I denne studien undersøkes det hvordan ... -
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 ... -
Prediksjon av tynningsbehov ved hjelp av data fra flybåren laserskanning
(Master thesis, 2012-06-18)Tynningsanbefalinger basert på data fra flybåren laserskanning er et nytt produkt fra takstselskapene, men metodene som ligger til grunn for anbefalingene er i dag lite kvalitetssikret. Hovedproblemstilling i denne oppgaven ... -
