Microclimatic comparison of lichen heaths and shrubs: Shrubification generates atmospheric heating but subsurface cooling during the growing season
Aartsma, Peter; Asplund, Johan; Odland, Arvid; Reinhardt, Stefanie; Renssen, Hans (Peer reviewed; Journal article, 2021)Lichen heaths are declining in abundance in alpine and Arctic areas partly due to an increasing competition with shrubs. This shift in vegetation types might have important consequences for the microclimate and climate on ... -
New records of lichenized and lichenicolous fungi in Scandinavia
Westberg, Martin; Timdal, Einar; Asplund, Johan; Bendiksby, Mika; Haugan, Reidar; Jonsson, Fredrik; Larsson, Per; Odelvik, Göran; Wedin, Mats; Millanes, Ana M. (Journal article; Peer reviewed, 2015) -
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. ... -
Simulated global warming increases usnic acid but reduces perlatolic acid in the mat-forming terricolous lichen Cladonia stellaris
Asplund, Johan; Siegenthaler, Andy; Gauslaa, Yngvar (Peer reviewed; Journal article, 2017)Lichens as sessile and slow-growing symbiotic associations have evolved various carbon-based secondary compounds (CBSCs) to mitigate the effects of some stressors in the extreme environments in which they often grow. The ... -
Spatial variation of surface soil carbon in a boreal forest – the role of historical fires, contemporary vegetation, and hydro-topography
Haukenes, Vilde Lytskjold; Åsgård, Lisa; Asplund, Johan; Nybakken, Line; Rolstad, Jørund; Storaunet, Ken Olaf; Ohlson, Mikael (Peer reviewed; Journal article, 2022)Knowledge about the spatial variation of boreal forest soil carbon (C) stocks is limited, but crucial for establishing management practices that prevent losses of soil C. Here, we quantified the surface soil C stocks across ... -
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 ... -
Three decades of environmental change studies at alpine Finse, Norway: climate trends and responses across ecological scales
Roos, Ruben Erik; Birkemoe, Tone; Asplund, Johan; Halbritter Rechsteiner, Aud Helen; Olsen, Siri Lie; Vassvik, Linn; van Zuijlen, Kristel; Klanderud, Kari (Peer reviewed; Journal article, 2022) -
Tree species effects on litter decomposition and soil carbon
Ransedokken, Yngvild (PhD thesis;2022:18, Doctoral thesis, 2022)Boreal forests soils play an important role in mitigating climate change as they are the largest terrestrial carbon pool. The accumulation of soil carbon is regulated by the balance of carbon and nitrogen input from plant ... -
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. ...
