Lack of population genetic structure of lumpfish along the Norwegian coast: A reappraisal based on EST-STRs analyses
(Peer reviewed; Journal article, 2022-04-13)Lumpfish is now the single most important cleaner fish species to date and there is an extensive lumpfish translocation along the Norwegian coast. A reliable baseline information about the population genetic structure of ... -
Lamb performance on island pastures in Northern Norway
(Peer reviewed; Journal article, 2020-07-14)The Norwegian sheep industry is based on utilization of “free” rangeland pasture resources. Use of mountain pastures is dominating, with about two million sheep grazing these pastures during summer. Regional challenges ... -
Land cover classification of treeline ecotones along a 1100 km latitudinal transect using spectral- and three-dimensional information from UAV-based aerial imagery
(Peer reviewed; Journal article, 2022-03-04)The alpine treeline ecotone is expected to move upwards in elevation with global warming. Thus, mapping treeline ecotones is crucial in monitoring potential changes. Previous remote sensing studies have focused on the usage ... -
Land cover in Norway based on an area frame survey of vegetation types
(Journal article; Peer reviewed, 2018-05-21)The Norwegian area frame survey of land cover and outfield land resources (AR18X18), completed in 2014, provided unbiased statistics of land cover in Norway. The article reports the new statistics, discusses implications ... -
Land cover segmentation of airborne LiDAR data using stochastic atrous network
(Journal article; Peer reviewed, 2018-06-19)Inspired by the success of deep learning techniques in dense-label prediction and the increasing availability of high precision airborne light detection and ranging (LiDAR) data, we present a research process that compares ... -
Land-use change in a Nordic future towards bioeconomy: A methodological framework to compare and merge stakeholder and expert opinions on qualitative scenarios
(Peer reviewed; Journal article, 2023-04-23)Future development of bioeconomy is expected to change land use in the Nordic countries in agriculture and forestry. The changes are likely to affect water quality due to changes in nutrient run-off. To explore possible ... -
Land-use dominates climate controls on nitrogen and phosphorus export from managed and natural Nordic headwater catchments
(Peer reviewed; Journal article, 2020-10)Agricultural, forestry‐impacted and natural catchments are all vectors of nutrient loading in the Nordic countries. Here, we present concentrations and fluxes of total nitrogen (totN) and phosphorus (totP) from 69 Nordic ... -
Large herbivores facilitate the persistence of rare taxa under tundra warming
(Peer reviewed; Journal article, 2022-01-25)Ecological rarity, characterized by low abundance or limited distribution, is typical of most species, yet our understanding of what factors contribute to the persistence of rare species remains limited. Consequently, ... -
Large scale mapping of forest attributes using heterogeneous sets of airborne laser scanning and National Forest Inventory data
(Peer reviewed; Journal article, 2021-09-29)Background The Norwegian forest resource map (SR16) maps forest attributes by combining national forest inventory (NFI), airborne laser scanning (ALS) and other remotely sensed data. While the ALS data were acquired over ... -
Large-scale genetic admixture suggests high dispersal in an insect pest, the apple fruit moth
(Peer reviewed; Journal article, 2020-08-12)Knowledge about population genetic structure and dispersal capabilities is important for the development of targeted management strategies for agricultural pest species. The apple fruit moth, Argyresthia conjugella ... -
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 ... -
Late-Autumn Ramet Sprouting of Three Arable Creeping Perennial Weed Species
(Peer reviewed; Journal article, 2022-09-13)Elymus repens (L.) Gould), Cirsium arvense (L.) Scop. and Sonchus arvensis L. are important arable creeping perennial weeds in Europe. These are clonal plants with subterranean reproductive organs (E. repens, rhizomes, the ... -
Leachability and Decay Resistance of Wood Polyesterified with Sorbitol and Citric Acid
(Peer reviewed; Journal article, 2020-06-06)Research Highlights: Polyesterification of wood with sorbitol and citric acid (SCA) increases decay resistance against brown-rot and white-rot fungi without reducing cell wall moisture content but the SCA polymer is susceptible ... -
Leachate emissions of short- and long-chain perand polyfluoralkyl substances (PFASs) from various Norwegian landfills
(Journal article; Peer reviewed, 2019)Restrictions on the use of long-chain per- and polyfluoralkyl substances (PFASs) has led to substitutions with short-chain PFASs. This study investigated the presence of four short-chain PFASs and twenty-four long-chain ... -
Leaching and surface runoff after fall application of fungicides on putting greens
(Peer reviewed; Journal article, 2020-12-08)Many greenkeepers and authorities are concerned about the environmental risks resulting from pesticide use on golf courses. We studied leaching and surface runoff of fungicides and metabolites during two winter seasons ... -
Leaching of Five Pesticides of Contrasting Mobility through Frozen and Unfrozen Soil
(Journal article; Peer reviewed, 2019)Field and laboratory studies show increased leaching of pesticides through macropores in frozen soil. Fast macropore flow has been shown to reduce the influence of pesticide properties on leaching, but data on these processes ... -
Learning for Sustainability in Horticultural Production in Arctic Norway
