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 ... -
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 ... -

(NIBIO Rapport;5(93) 2019, Research report, 2019-08-15)I denne rapporten presenteres resultater fra prognosekjøringer der vi har beregnet poensiell virkestilgang for et område avgrenset til fylkene Rogaland, Hordaland og Sogn og Fjordane, med utgangspunkt i data registrert på ... -
Evaluering av teknologiske løsninger mot tamreinpåkjørsel langs Nordlandsbanen
(NIBIO Rapport;5(99) 2019, Research report, 2019-09)Reindeer-train-collisions (RTC) are a challenge for Norwegian society and the northern Norwegian train company Bane NOR with regard to animal welfare, wildlife ecology, animal husbandry, reindeer herding and the working ... -
Evaluation of leaf-level optical properties employed in land surface models
(Journal article; Peer reviewed, 2019-09-05)Vegetation optical properties have a direct impact on canopy absorption and scattering and are thus needed for modeling surface fluxes. Although plant functional type (PFT) classification varies between different land ... -
Developing a monthly radiative kernel for surface albedo change from satellite climatologies of Earth's shortwave radiation budget: CACK v1.0
(Journal article; Peer reviewed, 2019-09-09)Due to the potential for land-use–land-cover change (LULCC) to alter surface albedo, there is need within the LULCC science community for simple and transparent tools for predicting radiative forcings (ΔF) from surface ... -
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 ... -
The effect of diammonium phosphate and sodium silicate on the adhesion and fire properties of birch veneer
(Peer reviewed; Journal article, 2019-09-24)In built environments the combustibility of wood is a great concern, which limits the use of wood as a building material due to legislation. The reaction-to-fire properties of wood can be altered with the use of fire-retardant ... -

Lønnsomhet ved grøfterensk etter hogst
(NIBIO Rapport;5(115) 2019, Research report, 2019-10)I Norge har store skogarealer tidligere blitt grøftet fordi grunnvannstanden var så høy at den hemmet skogens vekst. Dels er dette myrjord, dels fastmark. Når skogen på slike areal hogges går vegetasjonens vannforbruk mye ... -
Detecting change-point, trend, and seasonality in satellite time series data to track abrupt changes and nonlinear dynamics: A Bayesian ensemble algorithm
(Peer reviewed; Journal article, 2019-10)Satellite time-series data are bolstering global change research, but their use to elucidate land changes and vegetation dynamics is sensitive to algorithmic choices. Different algorithms often give inconsistent or sometimes ... -
European mushroom assemblages are darker in cold climates
(Peer reviewed; Journal article, 2019-10-10)Thermal melanism theory states that dark-colored ectotherm organisms are at an advantage at low temperature due to increased warming. This theory is generally supported for ectotherm animals, however, the function of colors ... -
Re-evaluation of the genus Englerodendron (Leguminosae–Detarioideae), including Isomacrolobium and Pseudomacrolobium
(Peer reviewed; Journal article, 2019-10-11)On the basis of a new phylogeny of the Detarioideae, with a particular focus on Englerodendron Harms, Anthonotha P.Beauv. and related genera, the possible options for delimiting monophyletic genera are discussed. As a ... -
Carnivore Management Zones and their Impact on Sheep Farming in Norway
(Journal article; Peer reviewed, 2019-10-17)We investigated the impact of Norway’s current zonal carnivore management system for four large carnivore species on sheep farming. Sheep losses increased when the large carnivores were reintroduced, but has declined again ... -
Large-scale genomic sequence data resolve the deepest divergences in the legume phylogeny and support a near-simultaneous evolutionary origin of all six subfamilies
(Peer reviewed; Journal article, 2019-10-30)Phylogenomics is increasingly used to infer deep‐branching relationships while revealing the complexity of evolutionary processes such as incomplete lineage sorting, hybridization/introgression and polyploidization. We ... -
A global view of aspen: Conservation science for widespread keystone systems
(Peer reviewed; Journal article, 2019-10-31)Across the northern hemisphere, six species of aspen (Populus spp.) play a disproportionately important role in promoting biodiversity, sequestering carbon, limiting forest disturbances, and providing other ecosystem ... -
