Long-term preservation of potato leafroll virus, potato virus S, and potato spindle tuber viroid in cryopreserved shoot tips
(Journal article; Peer reviewed, 2018-10-06)Availability of and easy access to diverse plant viruses and viroids is a prerequisite in applied and basic studies related to viruses and viroids. Long-term preservation of viruses and viroids is difficult. A protocol was ... -
Long-term spatiotemporal dynamics in a mountain birch (Betula pubescens ssp. czerepanovii) forest in south-east Norway
(Peer reviewed; Journal article, 2022-08-06)Mountain birch forest covers large areas in Eurasia, and their ecological resilience provides important ecosystem services to human societies. This study describes long-term stand dynamics based on permanent plots in the ... -
Longevity of plant pathogens in dry agricultural seeds during 30 years of storage
(Peer reviewed; Journal article, 2021-10-19)Plant diseases may survive and be spread by infected seeds. In this study we monitored the longevity of 14 seed-borne pathogens in 9 crop species commonly grown in the Nordic countries, in addition to a sample of sclerotia ... -
Longitudinal height-diameter curves for Norway spruce, Scots pine and silver birch in Norway based on shape constraint additive regression models
(Journal article; Peer reviewed, 2018-02-12)Background: Generalized height-diameter curves based on a re-parameterized version of the Korf function for Norway spruce (Picea abies (L.) Karst.), Scots pine (Pinus sylvestris L.) and silver birch (Betula pendula Roth) ... -
The look of agricultural landscapes – How do non-crop landscape elements contribute to visual preferences in a large-scale agricultural landscape?
(Peer reviewed; Journal article, 2020-04-27)Efficiency in agricultural food production has long been in focus and this has affected the spatial structure of agricultural land use. One outcome has been extensive criticism based on a wide range of negative consequences, ... -
Loss of species and genetic diversity during colonization: Insights from acanthocephalan parasites in northern European seals
(Peer reviewed; Journal article, 2023-10-19)Studies on host–parasite systems that have experienced distributional shifts, range fragmentation, and population declines in the past can provide information regarding how parasite community richness and genetic diversity ... -
Losses and grass silage quality in bunker silos compacted by tractor versus wheel loader
(Peer reviewed; Journal article, 2020-04-27)The study aimed to explore whether an increase in bunker silage density obtained by turning to a heavier packing machine than a farm size tractor would reduce losses and improve grass silage quality and aerobic stability. ... -
Low genetic variation of invasive Fallopia spp. in their northernmost European distribution range
(Journal article; Peer reviewed, 2017)Knowledge about the reproduction strategies of invasive species is fundamental for effective control. The invasive Fallopia taxa (Japanese knotweed s.l.) reproduce mainly clonally in Europe, and preventing spread of ... -
Low impact of dry conditions on the CO2 exchange of a Northern-Norwegian blanket bog
(Journal article; Peer reviewed, 2015)Northern peatlands hold large amounts of organic carbon (C) in their soils and are as such important in a climate change context. Blanket bogs, i.e. nutrient-poor peatlands restricted to maritime climates, may be extra ... -
Low precipitation due to climate change consistently reduces multifunctionality of urban grasslands in mesocosms
(Peer reviewed; Journal article, 2023-02-03)Urban grasslands are crucial for biodiversity and ecosystem services in cities, while little is known about their multifunctionality under climate change. Thus, we investigated the effects of simulated climate change, i.e., ... -
Low temperature treatment affects concentration and distribution of Chrysanthemum stunt viroid in Argyranthemum
(Journal article; Peer reviewed, 2016)Chrysanthemum stunt viroid (CSVd) can infect Argyranthemum and cause serious economic loss. Low temperature treatment combined with meristem culture has been applied to eradicate viroids from their hosts, but without success ... -
Low-cost investment with high quality performance. Bleaching earths for phosphorus reduction in the low-temperature bleaching process of rapeseed oil
(Peer reviewed; Journal article, 2020-05-08)Rapeseed oils are a valuable component of the diet. Mostly, there are refined oils deprived of valuable nutrients in the market, hence in recent times cold-pressed and unrefined oils have been available and popular among ... -
The lunar nodal phase cycle and winter atmospheric pressure as possible determinants of moth abundance: Analyses of a 30-year time series from South Norway
(Peer reviewed; Journal article, 2022-10-27)According to the plant stress hypothesis, population peaks of herbivores such as moths are caused by plant stress factors that force plants to reallocate stored defensive proteins to transportable and easily digestive ... -
MA-packages in simulated retail conditions maintained sweet cherry fruit quality
(Journal article; Peer reviewed, 2018)Modified atmosphere packaging (MAP) may inhibit undesirable quality changes of fruit and vegetables. The aim of this experiment was to evaluate the effect of MAP on selected quality parameters for sweet cherries (Prunus ... -
Macrobiological Degradation of Esterified Wood with Sorbitol and Citric Acid
(Peer reviewed; Journal article, 2020-07-19)There is a need for new solutions in wood protection against marine wood borers and termites in Europe. A new solution could be the esterification of wood with sorbitol and citric acid (SCA) since these are inexpensive and ... -
Macronutrient balancing in free-ranging populations of moose
(Peer reviewed; Journal article, 2021-07-15)At northern latitudes, large spatial and temporal variation in the nutritional composition of available foods poses challenges to wild herbivores trying to satisfy their nutrient requirements. Studies conducted in mostly ... -
