Stem taper and bark functions for Norway spruce in Norway
(Journal article; Peer reviewed, 2019-09-16)Based on data from long-term experimental fields with Norway spruce (Picea abies (L.) H. Karst.), we developed new stem taper and bark functions for Norway. Data was collected from 477 trees in stands across Norway. Three ... -
Importance of Surface Roughness for the Local Biogeophysical Effects of Deforestation
(Journal article; Peer reviewed, 2019-08-14)Deforestation influences surface properties such as surface roughness, resulting in changes in the surface energy balance and surface temperature. Recent studies suggest that the biogeophysical effects are dominated by ... -
Estimating stand level stem diameter distribution utilizing harvester data and airborne laser scanning
(Journal article; Peer reviewed, 2019-08-07)Accurately positioned single-tree data obtained from a cut-to-length harvester were used as training harvester plot data for k-nearest neighbor (k-nn) stem diameter distribution modelling applying airborne laser scanning ... -
Mass spectrometry reveals the presence of specific set of epigenetic DNA modifications in the Norway spruce genome
(Journal article; Peer reviewed, 2019-12-17)5-Methylcytosine (5mC) is an epigenetic modification involved in regulation of gene expression in metazoans and plants. Iron-(II)/α-ketoglutarate-dependent dioxygenases can oxidize 5mC to 5-hydroxymethylcytosine (5hmC), ... -
Belowground Biodiversity Relates Positively to Ecosystem Services of European Forests
(Journal article; Peer reviewed, 2019-03-19)Biodiversity of ecosystems is an important driver for the supply of ecosystem services to people. Soils often have a larger biodiversity per unit surface area than what can be observed aboveground. Here, we present what ... -
