Long-term effects of environmentally relevant doses of 2,2 ',4,4 ',5,5 ' hexachlorobiphenyl (PCB153) on neurobehavioural development, health and spontaneous behaviour in maternally exposed mice
(Journal article; Peer reviewed, 2011-01-13)Background: Polychlorinated biphenyls (PCBs) are widespread in the environment, human food and breast milk. Seafood is known to contain nutrients beneficial for the normal development and function of the brain, but also ... -
The long-term fate of deposited nitrogen in temperate forest soils
(Peer reviewed; Journal article, 2020-06-20)Increased anthropogenic nitrogen (N) inputs can alter the N cycle and affect forest ecosystem functions. The impact of increased N deposition depends among others on the ultimate fate of N in plant and soil N pools. ... -
Long-term monitoring of protected Cultural Heritage Environments in Norway: Development of methods and first-time application
(Journal article; Peer reviewed, 2019-04-27)Norway has a political goal to minimize the loss of cultural heritage due to removal, destruction or decay. On behalf of the national Directorate for Cultural Heritage, we have developed methods to monitor Cultural Heritage ... -
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 ... -
