AUTOMATED UPDATING OF FOREST COVER MAPS FROM CLOUD-FREE SENTINEL-2 MOSAIC IMAGES USING OBJECT-BASED IMAGE ANALYSIS AND MACHINE LEARNING METHODS
(Peer reviewed; Journal article, 2020-08-03)Planning sustainable use of land resources and environmental monitoring benefit from accurate and detailed forest information. The basis of accurate forest information is data on the spatial extent of forests. In Norway ... -
Bark Beetle-Associated Blue-Stain Fungi Increase Antioxidant Enzyme Activities and Monoterpene Concentrations in Pinus yunnanensis
(Journal article; Peer reviewed, 2018-11-27)Yunnan pine is the most important tree species in SW China in both economical and ecological terms, but it is often killed by pine shoot beetles (Tomicus spp.). Tomicus beetles are secondary pests in temperate regions and ... -
Behavioral responses of terrestrial mammals to COVID-19 lockdowns
(Peer reviewed; Journal article, 2023-06-08)COVID-19 lockdowns in early 2020 reduced human mobility, providing an opportunity to disentangle its effects on animals from those of landscape modifications. Using GPS data, we compared movements and road avoidance of ... -
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 ... -
Benthic Microbial Communities in a Seasonally Ice-Covered Sub-Arctic River (Pasvik River, Norway) Are Shaped by Site-Specific Environmental Conditions
(Peer reviewed; Journal article, 2022-05-12)The Pasvik River experiences chemical, physical, and biological stressors due to the direct discharges of domestic sewage from settlements located within the catchment and runoff from smelter and mine wastes. Sediments, ... -
Bilberry seed production explains spatiotemporal synchronicity in bank vole population fluctuations in Norway
(Peer reviewed; Journal article, 2021-01-12)Population fluctuations of small rodents are often synchronized over larger areas (>100 km) than what could be explained by dispersal, suggesting that the synchronizing factor is weather-related and possibly mediated through ... -
Biological durability of pine wood
(Peer reviewed; Journal article, 2022-08-08)The genus Pinus represents more than a hundred different tree species, most of them forming stems that can be commercially utilised for both timber and wood pulp industry. Pines are native to most of the Northern Hemisphere, ... -
Biotic threats for 23 major non-native tree species in Europe
(Peer reviewed; Journal article, 2021-08-06)For non-native tree species with an origin outside of Europe a detailed compilation of enemy species including the severity of their attack is lacking up to now. We collected information on native and non-native species ... -
Body Temperature and Activity Rhythms Under Different Photoperiods in High Arctic Svalbard ptarmigan (Lagopus muta hyperborea)
(Peer reviewed; Journal article, 2021-03-08)Organisms use circadian rhythms to anticipate and exploit daily environmental oscillations. While circadian rhythms are of clear importance for inhabitants of tropic and temperate latitudes, its role for permanent residents ... -
Boreal tree species change as a climate mitigation strategy: impact on ecosystem C and N stocks and soil nutrient levels
(Peer reviewed; Journal article, 2021-11-24)To increase the annual uptake of CO2 as well as the long-term storage of carbon (C) in forests, the Norwegian government consider large-scale replacements of native, deciduous forests with faster-growing species like Norway ... -
Building a high-resolution site index map using boosted regression trees: The Norwegian case
(Peer reviewed; Journal article, 2023-03-15)Accurate estimation of site productivity is essential for forest projections and scenario modelling. We present and evaluate models to predict site index (SI) and whether a site is productive (potential total stem volume ... -
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 ... -
Cell wall changes during brown rot degradation of furfurylated and acetylated wood
(Peer reviewed; Journal article, 2021-05-30)This study explores cell wall changes in Radiata pine (Pinus radiata) after modification with acetylation or furfurylation and subsequent prolonged subjection to the brown rot fungus R. placenta with the aim of better ... -
A century of National Forest Inventory in Norway – informing past, present, and future decisions
(Peer reviewed; Journal article, 2020-07-17)Past: In the early twentieth century, forestry was one of the most important sectors in Norway and an agitated discussion about the perceived decline of forest resources due to over-exploitation was ongoing. To base the ... -
A chlorophyll-deficient, highly reflective soybean mutant: radiative forcing and yield gaps
(Peer reviewed; Journal article, 2020-06-22)Sunlight absorbed at the Earth’s surface is re-emitted as longwave radiation. Increasing atmospheric concentrations of CO2 and other greenhouse gases trap an increasing fraction of such heat, leading to global climate ... -
Climate change drives substantial decline of understorey species richness and abundance in Norway spruce forests during 32 years of vegetation monitoring
(Peer reviewed; Journal article, 2023-05-31)Questions Observations in permanent forest vegetation plots in Norway and elsewhere indicate that complex changes have taken place over the period 1988–2020. These observations are summarised in the “climate-induced ... -
Climate change mitigation potential of biochar from forestry residues under boreal condition
(Peer reviewed; Journal article, 2021-10-18)Forest harvest residue is a low-competitive biomass feedstock that is usually left to decay on site after forestry operations. Its removal and pyrolytic conversion to biochar is seen as an opportunity to reduce terrestrial ... -
Climate targets in European timber-producing countries conflict with goals on forest ecosystem services and biodiversity
(Peer reviewed; Journal article, 2023-04-14)The European Union (EU) set clear climate change mitigation targets to reach climate neutrality, accounting for forests and their woody biomass resources. We investigated the consequences of increased harvest demands ... -
