The Qualitative and Quantitative Compositions of Phenolic Compounds in Fruits of Lithuanian Heirloom Apple Cultivars
(Peer reviewed; Journal article, 2020-11-11)As the interest in heirloom cultivars of apple trees, their fruit, and processed products is growing worldwide, studies of the qualitative and quantitative composition of biological compounds are important for the evaluation ... -
Qualitative evaluation of nine agricultural methods for increasing soil carbon storage in Norway
(Peer reviewed; Journal article, 2024-05-22)Carbon content is a key property of soils with importance for all ecosystem functions. Measures to increase soil carbon storage are suggested with the aim to compensate for agricultural emissions. In Norway, where soils ... -
Quality of fish sludge as fertiliser to spring cereals: Nitrogen effects and environmental pollutants
(Peer reviewed; Journal article, 2023-03-14)The aim of this study was to contribute to development of organic fertiliser products based on fish sludge (i.e. feed residues and faeces) from farmed smolt. Four dried fish sludge products, one liquid digestate after ... -
Quality variation in comminuted forest fuels delivered during the winter in north Sweden
(Peer reviewed; Journal article, 2020-10-17)Swedish legislation stipulates the precision required for estimates of parameters used to determine the value of various forest fuels. The net energy value of fuel, as it is received, is often used to set the trade price. ... -
Quantification of accuracy in field-based land cover maps: A new method to separate different components
(Peer reviewed; Journal article, 2021-04-02)Aim Many thematic land cover maps, such as maps of vegetation types, are based on field inventories. Studies show inconsistencies among field workers in such maps, explained by inter-observer variation in classification ... -
Quantifying historical landscape change with repeat photography: an accuracy assessment of geospatial data obtained through monoplotting
(Peer reviewed; Journal article, 2021-01-20)Traditional landscape photographs reaching back until the second half of the nineteenth century represent a valuable image source for the study of long-term landscape change. Due to the oblique perspective and the lack of ... -
Quantifying regional surface energy responses to forest structural change in Nordic Fennoscandia
(Peer reviewed; Journal article, 2020-07-16)In a climate model, surface energy and water fluxes of the vegetated ecosystem largely depend on important structural attributes like leaf area index and canopy height. For forests, management can greatly alter these ... -
Quantifying the drivers of the increasing colored organic matter in boreal surface waters
(Journal article; Peer reviewed, 2010-03-23)Long-term monitoring of surface water quality has shown increasing concentrations of colored dissolved organic matter (CDOM) across large parts of the northern latitudes. This has increased purification costs for domestic ... -
Quantitative and qualitative workload assessment in steep terrain forest operations: fostering a safer work environment through yarder automation
(Peer reviewed; Journal article, 2022-09-27)Many forestry roles have changed from being manual tasks with a high physical workload to being a machine operator task with a high mental workload. Automation can support a decrease in mental fatigue by removing tasks ... -
Quantitative assessment of observed versus predicted responses to selection
(Peer reviewed; Journal article, 2021-06-17)Although artificial-selection experiments seem well suited to testing our ability to predict evolution, the correspondence between predicted and observed responses is often ambiguous due to the lack of uncertainty estimates. ... -
Quantitative trait loci associated with different polar metabolites in perennial ryegrass - providing scope for breeding towards increasing certain polar metabolites
(Journal article; Peer reviewed, 2017-10-10)Background Recent advances in the mapping of biochemical traits have been reported in Lolium perenne. Although the mapped traits, including individual sugars and fatty acids, contribute greatly towards ruminant productivity, ... -
Radiative forcing bias of simulated surface albedo modifications linked to forest cover changes at northern latitudes

Radical Scavenging and Antimicrobial Properties of Polyphenol Rich Waste Wood Extracts
(Peer reviewed; Journal article, 2020-03-10)The main focus of this study is to assess radical scavenging and antimicrobial activities of the 11 wood extracts: oak (Quercus petraea (Matt.) Liebl., Q. robur L., and Q. cerris L.), mulberry (Morus alba L.), myrobalan ... -
Rahnella spp. are commonly isolated from onion (Allium cepa) bulbs and are weakly pathogenic
(Journal article; Peer reviewed, 2019)Aims Bacterial decays of onion bulbs have serious economic consequences for growers, but the aetiologies of these diseases are often unclear. We aimed to determine the role of Rahnella, which we commonly isolated from bulbs ... -
Raman micro-spectroscopy of two types of acetylated Norway spruce wood at controlled relative humidity
(Peer reviewed; Journal article, 2022-09-06)Water is a key element for wood performance, as water molecules interact with the wood structure and affect important material characteristics such as mechanical properties and durability. Understanding wood-water interactions ... -
Range expansion of the small spruce bark beetle Ips amitinus: a newcomer in northern Europe
(Journal article; Peer reviewed, 2019)1 Ips amitinus arrived in Northern Europe at the beginning of 1900s, although its recent expansions to the northernmost conifers have been rapid. 2 Analyses of recent records, MaxEnt models and regional population size ... -
Range-wide whole-genome resequencing of the brown bear reveals drivers of intraspecies divergence
(Peer reviewed; Journal article, 2023-02-06)Population-genomic studies can shed new light on the effect of past demographic processes on contemporary population structure. We reassessed phylogeographical patterns of a classic model species of postglacial recolonisation, ... -
