Condensed tannins in senesced foliage and soil organic layer in response to fertilization in boreal forest ecosystem
Ferdous, Zannatul (Master thesis, 2021)Anthropogenic nitrogen deposition rate in boreal forests increased over the last century and significantly impacted many parts of these ecosystems. Boreal forests contain a large amount of carbon (C), and nitrogen (N) is ... -
Effect of nitrogen fertilization on decomposition in boreal forest
Subedi, Puspa (Master thesis, 2021)Anthropogenic activities have resulted in escalating deposition of nitrogen in many forms that impact several aspects of ecosystem especially lying on boreal region where N is a limiting factor for tree growth. Although N ... -
Effects of boreal forest fertilization on carbon storage and ectomycorrhizal fungi
Hauken, Karsten Nordal (Master thesis, 2020)Boreal forests represent a large fraction of the global carbon (C) stock. Increasing attention is given to utilizing these forests in the battle against climate changed driven by increased atmospheric CO2. Part of this ... -
Effects of elevation on the lichen community palatability in an alpine ecosystem
Levavasseur, Gaspard Paul Yves Marie (Master thesis, 2021)Lichens are present in almost all terrestrial ecosystems, and in some of them, they are the main primary producers. Most studies focus on vascular plant communities, even studies on ecosystems where lichens represent an ... -
Effects of long-term experimental warming on alpine bryophytes : trends in functional traits
Dahle, Oda Sofie (Master thesis, 2019)Functional traits are becoming increasingly important tools to evaluate plant community response to climate change. Artificial warming treatments can shift community-level trait values as a consequence of intraspecific ... -
Effekt av skoggjødsling på det kjemiske forsvaret hos gran (Picea abies)
Selmer, Ruben Nikolai (Master thesis, 2018)For at Norge skal nå målene i klimameldingen har staten gitt tilskudd til skoggjødsling som et av flere virkemidler. Innen skogbruket har gjødsling blitt godt mottatt og blitt en av de mest lønnsomme investeringene etter ... -
Foliar phenols in beech (Fagus sylvatica L.) seedlings of six European provenances from a latitudinal gradient grown in three common gardens in Norway
Steen, Johanna Sætherø (Master thesis, 2020)With progressive climate change, the total concentration and composition of the chemical defense in European beech (Fagus sylvatica L.) is likely to change, which might impact its fitness and ability to establish beyond ... -
Hvordan ettervirkningene av en 26 år gammel fin-skala forstyrrelse og lystilgang i skogbunnen påvirker etablering og vekst hos gran, furu, rogn, bjørk og hårfrytle i en granskog i SØ-Norge
Lima, Oline Rosnes (Master thesis, 2021)Forstyrrelser og suksesjoner er en del av den naturlige dynamikken i boreal skog, og skaper store og små, romlige og tidsmessige endringer. Endringene fører til heterogenitet i økosystemene og kan øke artsdiversiteten. ... -
Long-term experimental warming in an alpine heath : decrease in cover of the most abundant bryophytes
Sundsbø, Snorre (Master thesis, 2019)Alpine ecosystems have shown to be sensitive to climate warming. Bryophytes are particularly important in alpine ecosystems and are known to support ecosystem services such as water regulation, nitrogen fixation and carbon ... -
Papir som fysisk beskyttelse av granplanter (Picea abies) mot gransnutebillen (Hylobius abietis)
Grande, Erlend (Master thesis, 2021)En vellykket foryngelse er viktig for å sikre en bærekraftig skogforvaltning. Foryngelse av gran (Picea abies) foregår i all hovedsak gjennom planting. Gransnutebillen (Hylobius abietis) utgjør en stor fare for granplanter ... -
Phenolic defense mechanisms in needles of nursery plants and naturally regenerated Norway spruce (Picea abies)
de Ruiter, Femke Emma (Master thesis, 2022)To incorporate sustainable management in increasing forestry practices in Norway, low impact management of Pine weevils (Hylobius abietis), the most common pest on clear cut area in boreal silviculture, is of great importance. ... -
Stående og induserbart fenolforsvar hos kulturplanter og naturlig foryngelse av gran (Picea abies)
Lomsdal, Maren (Master thesis, 2020)Foryngelse er et viktig tiltak for å sikre bærekraftig forvaltning av skogen. Gran (Picea abies) forynges i hovedsak ved hjelp av foredlede planter som gir økt skogproduksjon sammenlignet med naturlig foryngelse. Gransnutebilla ... -
The effect of long-term experimental warming on lichens and vascular plants in an alpine Dryas heath
Hasvik, Åshild (Master thesis, 2018)Global warming affects species diversity and ecosystems throughout the world, and alpine and arctic plant communities are considered to be particularly sensitive. During the last decades, several studies have shown a shift ... -
Variable soil carbon stocks across fine spatial scales in a natural boreal forest landscape
Åsgård, Lisa (Master thesis, 2021)Boreal forests, and especially boreal forest soils, are of considerable importance in global carbon dynamics and climate regulation. There are several studies that have modelled and quantified boreal soil carbon stocks, ... -
Vascular plant and lichen functional trait responses to warming in an alpine ecosystem
Knutsen, Maria Skar (Master thesis, 2018)Functional traits are recognized as potential predictors of plant community responses to climate change. In stressful alpine environments, temperature is a limiting factor and may select for resource conservative individuals. ...
