Naturskogsbegrepet i "Natur i Norge" (NiN) og sammenheng med målt epifyttisk lavbiomasse
(Master thesis, 2018)Mer enn 40 % av Norges landareal er dekket av skog og omtrent 60% av alle landets kjente arter er knyttet til dette biomet. Skogbruk har vært en viktig næring i landet i lengre tid, og skogbruket i Norge og Fennoskandia ... -
Naturtypekartlegging i Vindafjord kommune
(Master thesis, 2010-12-03)FN har bestemt at 2010 skal vera det internasjonale Naturmangfaldåret. Dette er for å setja fokus på biomangfaldet i verda, og gjera folk meir bevisste på kor viktig naturen og det biologiske mangfaldet er. Kartlegging ... -
Når er det realistisk at hele fjernvarmesektoren i Norge kan bli 100% fornybar?
(Master thesis, 2015-08-03)Historically, the district-heating industry in Norway has been predominantly driven by fossil energy. More recently, however, there has been a dramatic increase in heat produced from renewable energy sources. This thesis ... -
Når sjøen kommer til syne: Restaurering av kystlynghei ved fjerning av sitkagran (Picea sitchensis) på Silda og Kvalheim
(Master thesis, 2023)Kystlynghei er blant de semi-naturlige naturtypene på rødlisten for naturtyper, med kategori sterkt truet (EN). Naturtypen er i sterk tilbakegang grunnet opphørt drift, siden kystlyngheien er avhengig av helårsbeite og ... -
Nedvasking av fosfor gjennom ulike jordprofiler fra Jæren. Lysimeter forsøk.
(Master thesis, 2014-08-04)Sammendrag. Dette forsøket er utført i samarbeid mellom Bioforsk og NMBU. På Jæren i Rogaland praktiseres det intensivt landbruk. Høy Husdyrtetthet sammen med intensiv gjødsling har ført til at mellom 50 – 60 % av den ... -
Neighboring colonies of Brandt’s bat Myotis brandtii and Whiskered bat M. mystacinus changed their roost activity throughout the breeding season
(Master thesis, 2019)Little is known about bats in Norway, although they constitute > 20 % of our terrestrial mammal species; 13 bats species are registered, but it is not known if all of these reproduce in the country. Many European bat ... -
Nest box selection in the Eurasian kestrel (Falco Tinnunculus) in the Trysil region in Norway
(Master thesis, 2012-09-12)Nest box selection in the Eurasian kestrel (Falco tinnunculus) in Southern Norway was estimated from fieldwork in Trysil Municipality in 2007 and by use of additional field data from 2005 and 2006. Used versus not used ... -
Nesting behaviour of Black Skimmers (Rynchops niger) along the Manu River, Peru
(Master thesis, 2016-08-31)The Black Skimmer (Rynchops niger) nests on the river beaches in the Amazon region during the dry season, where there a lack of studies on its habitat selection and behaviour during nesting. The species exhibits biparental ... -
Niche differentiation among boreal mammals and birds regarding their roles as endozoochorical seed dispersers
(Master thesis, 2019)Plant seed dispersal by endozoochory (seed dispersal via the digestive system of animals) is an important process affecting plant species composition in ecosystems. Recent studies in temperate regions have shown that a ... -
Nitrogen deposition linked to changes in flowering plant and wild bee diversity
(Master thesis, 2022)Nitrogen (N) deposition from anthropogenic activities is a major threat to plant biodiversity, but few studies have investigated effects of N deposition on higher trophic levels, such as on flower-visiting insects. N ... -
Nitrogen dynamics in an organic green manure - cereal rotation and mineralization of clover leaves at low temperature
(PhD Thesis;2016:25, Doctoral thesis, 2017-07-12)In northern temperate regions, grass-clover green manure leys are commonly used as a break crop in stockless organic cereal rotations in order to provide soil fertility and reduce the pressure of weeds, pests and diseases, ... -
Nitrogen turnover and N2O emissions as a function of edaphic and hydrological conditions in subtropical forests of South China
(PhD Thesis;2016:81, Doctoral thesis, 2017-07-12)Forests in the Chinese subtropics receive large amounts of nitrogen (N) from the atmosphere, both as ammonium (NH4 +) and nitrate (NO3 -). Many of these forests are considered to be “N-saturated”, i.e. are not able to ... -
Nitrogenrensning for avrenning fra anleggsvirksomhet og sprengsteinsdeponi.
(Master thesis, 2023)Norge benyttes nesten 70 000 tonn av sivilt sprengstoff. Sprengstoffet som benyttes inneholder om lag 70 % ammoniumnitrat. Fra dette har det blitt beregnet et nitrogentap til vannforekomster ligger på om lag 3000 tonn. Det ... -
Nitrous oxide emission and turnover in arable cropping in South East Norway
(PhD Thesis;2020:18, Doctoral thesis, 2020)Nitrogen is essential for all life on Earth. With an increasing global population, the use of reactive nitrogen has increased over the last century, resulting in increasing nitrogen pollution. Leaching of nitrate (NO3-) ... -
Non-Invasive Monitoring of Insectivorous Bats and Insects in Boreal Forest Habitats
(Master thesis, 2023)Abstract 1. All the Norwegian bat species depend on forest habitats in some parts of their annual cycle. Despite many of the Norwegian bat species being categorised as threatened on the Norwegian Red List and playing key ... -
