Climate warming feedback from mountain birch forest expansion: Reduced albedo dominates carbon uptake
(Journal article; Peer reviewed, 2013)Expanding high elevation and high latitude forest has contrasting climate feedbacks through carbon sequestration (cooling) and reduced surface reflectance (warming), which are yet poorly quantified. Here, we present an ... -
Climatic and soil factors explain the two-dimensional spectrum of global plant trait variation
(Peer reviewed; Journal article, 2021-12-23)Plant functional traits can predict community assembly and ecosystem functioning and are thus widely used in global models of vegetation dynamics and land–climate feedbacks. Still, we lack a global understanding of how ... -
Clonal growth buffers the effect of grazing management on the population growth rate of a perennial grassland herb
(Journal article; Peer reviewed, 2016-04-19)Grazing is an important management action to conserve biodiversity in semi-natural grasslands but it is important to understand how grazing influences the life-history components and population dynamics of plant species. ... -
Clopyralid applied to winter oilseed rape (Brassica napus L.) contaminates the food products nectar, honey and pollen
(Peer reviewed; Journal article, 2022-05-28)Clopyralid is a systemic herbicide used in oilseed rape and other crops. It was found in Danish honey from 2016 in concentrations exceeding the maximum residue level (MRL) of 0.05 mg kg−1. About 50% of the Danish honey is ... -
Closing global P cycles: The effect of dewatered fish sludge and manure solids as P fertiliser
(Peer reviewed; Journal article, 2021-09-09)The aim of this study was to contribute to closing global phosphorus (P) cycles by investigating and explaining the effect of fish sludge (feed residues and faeces of farmed fish) and manure solids as P fertiliser. Phosphorus ... -
A Cloud-Free Approach to Modeling Daily Downwelling Longwave Irradiance at Global Scale
(Peer reviewed; Journal article, 2023-06-27)Parametric modeling of downwelling longwave irradiance under all-sky conditions (LW↓) typically involves “correcting” a clear- (or non-overcast) sky model estimate using solar-irradiance-based proxies of cloud cover in ... -
CNash - A novel parameter predicting cake solids of dewatered digestates
(Journal article; Peer reviewed, 2019-04-23)Efficient digestate dewatering is crucial to reduce the volume and transportation cost of solid residues from anaerobic digestion (AD) plants. Large variations in dewatered cake solids have been reported and predictive ... -
Co-composting of digestate and garden waste with biochar: effect on greenhouse gas production and fertilizer value of the matured compost
(Peer reviewed; Journal article, 2022-06-22)Biogas digestate is a nitrogen (N) rich waste product that has potential for application to soil as a fertilizer. Composting of digestate is recognized as an effective step to reduce potentially negative consequences of ... -
CO2-equivalence metrics for surface albedo change based on the radiative forcing concept: a critical review
(Journal article, 2021-07-01)Management of Earth’s surface albedo is increasingly viewed as an important climate change mitigation strategy both on (Seneviratne et al., 2018) and off (Field et al., 2018; Kravitz et al., 2018) the land. Assessing the ... -
Coastal heathland vegetation is surprisingly resistant to experimental drought across successional stages and latitude
(Peer reviewed; Journal article, 2021-09-28)In the last decade, several major dwarf-shrub dieback events have occurred in northern European coastal heathlands. These dieback events occur after extended periods with sub-zero temperatures under snow-free conditions ... -
Coffee, child labour, and education: Examining a triple social–ecological trade-off in an Afromontane forest landscape
(Peer reviewed; Journal article, 2022-10-08)In biodiversity rich agriculture–forest moasic landscapes in south-western Ethiopia, the production of coffee and food crops, including guarding them from forest-dwelling mammals, requires a high input of labour, which is ... -
Cold acclimation in warmer extended autumns impairs freezing tolerance of perennial ryegrass (Lolium perenne) and timothy (Phleum pratense)
(Journal article; Peer reviewed, 2017-02-01)The effect of variable autumn temperatures in combination with decreasing irradiance and daylength on photosynthesis, growth cessation and freezing tolerance was investigated in northern- and southern-adapted populations ... -
Combined column test for characterization of leaching and transport of trace elements in contaminated soils
(Peer reviewed; Journal article, 2023-02-24)Environmental assessments are required prior to remediation and redevelopment of contaminated sites. To date, regulatory guidelines are commonly based on total concentrations. Occasionally, simple leaching procedures are ... -
The combined effects of centralization and carnivore management on sheep farmers and sheep farming in Norway
(Peer reviewed; Journal article, 2020-09-12)Sheep farmers in areas with large carnivores experience economic loss, psychological stress, and perceived alienation from political processes. This can result in decisions that differ from those made by farmers in areas ... -
Combined effects of climate change and policy uncertainty on the agricultural sector in Norway
(Journal article; Peer reviewed, 2017-05)Farmers are exposed to climate change and uncertainty about how that change will develop. As farm incomes, in Norway and elsewhere, greatly depend on government subsidies, the risk of a policy change constitutes an additional ... -
Combining FDR and ERT for monitoring soil moisture and temperature patterns in undulating terrain in south-eastern Norway
(Peer reviewed; Journal article, 2022-02-21)The occurrence of freeze–thaw cycles modifies water infiltration processes and surface runoff generation. Related processes are complex and are not yet fully investigated at field scale. While local weather conditions and ... -
