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 ... -
Prediksjon av vankant på plank ved hjelp av data fra automatmåling
(Master thesis, 2013-07-09)Bergene Holm avd. Haslestad er et relativt stort sagbruk i norsk sammenheng som produserer det meste innenfor trelast. Der har man observert en betydelig andel planker med vankant på midten. Dette er et problem fordi det ... -
Prediksjonsmodeller for bonitet ved hjelp av flybåren laserskanning og digitale kartdata
(Master thesis, 2012-06-18)I frykt for knapphet på de norske skogressursene ble det på starten av 1900-tallet et større fokus på en bærekraftig skogforvaltning med skogbruksplanlegging som verktøy. Etter bestandsskogbrukets inntog på 1950-tallet ble ... -

Prey choice, prey deliveries and prey handling in a generalist predator : video monitoring at a nest of the eagle owl (Bubo bubo)
(Master thesis, 2016-07-26)To record prey delivery and handling, and nest of the eagle owl (Bubo bubo), a breeding pair was video monitored during 6 June – 25 July in Meland municipality in Hordaland County, Norway. A total of 49 prey items were ... -
Prey deliveries at nests of the tawny owl (Strix aluco): diet and diel pattern
(Master thesis, 2016-03-30)I used continuous video monitoring to record prey items delivered at four tawny owl (Strix aluco) nests in Akershus county in southeast Norway during May 2014. A total of 1635.5 hours of video recordings were gathered, and ... -
Prey delivery and diet of the Eurasian kestrel (Falco tinnunculus) in a peak year of the wood lemming (Myopus schisticolor)
(Master thesis, 2012-09-12)I used video monitoring to study diet and prey delivery rate of six breeding pairs of the Eurasian kestrel (Falco tinnunculus) in Trysil, south eastern Norway, during the breeding season 2011. A total of 284 prey items ... -
