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. ... -
Characterisation of Postia placenta colonisation during 36 weeks in acetylated southern yellow pine sapwood at three acetylation levels including genomic DNA and gene expression quantification of the fungus
(Journal article; Peer reviewed, 2016-05-09)One way to protect timber in service against basidiomycete deterioration is by means of acetylation via reaction with acetic anhydride. The reason why acetylated wood (WAc) is resistant against decay fungi is still not ... -
Using Optical Sensors to Identify Water Deprivation, Nitrogen Shortage, Weed Presence and Fungal Infection in Wheat
(Journal article; Peer reviewed, 2016-05-26)The success of precision agriculture relies largely on our ability to identify how the plants’ growth limiting factors vary in time and space. In the field, several stress factors may occur simultaneously, and it is thus ... -
Effect of replacing organic grass-clover silage from primary growth with regrowth on N digestion in dairy cows
(Journal article; Peer reviewed, 2016-07-22)Clover proportions, and thereby chemical composition of herbage, differ between primary growth (PG) and regrowth (RG) in organic managed grass-clover fields. The characteristics of PG and RG silages suggest different ... -
Balancing public goods in agriculture through safe minimum standards
(Journal article; Peer reviewed, 2016-08-05)We develop a general framework in which public goods are conflicting (complementary) if an increase in the provision of one public good raises (lowers) the marginal cost of providing another public good. The framework is ... -
Functional growth analysis of ‘Sonata’ strawberry plants grown under controlled temperature and daylength conditions
(Journal article; Peer reviewed, 2016-08-17)In order to investigate the relationship between environmental conditions and vegetative growth and reproductive development in the strawberry, freshly rooted runner plants of the cultivar ‘Sonata’ were grown in a phytotron ... -
Positive responses of coastal dune plants to soil conditioning by the invasive Lupinus nootkatensis
(Journal article; Peer reviewed, 2016-08-26)Invasive nitrogen-fixing plants drive vegetation dynamics and may cause irreversible changes in nutrient-limited ecosystems through increased soil resources. We studied how soil conditioning by the invasive alien Lupinus ... -
Conflicting interests of ecosystem services: Multi-criteria modelling and indirect evaluation of trade-offs between monetary and non-monetary measures
(Journal article; Peer reviewed, 2016-10-19)Ecosystems provide services for many stakeholder groups, often with a conflict of interests that hampers sustainability. Core to these conflicts is the challenge of trading-off monetary and non-monetary measures. Using the ... -
DON content in oat grains in Norway related to weather conditions at different growth stages
(Journal article; Peer reviewed, 2016-12)High concentrations of the mycotoxin deoxynivalenol (DON), produced by Fusarium graminearum have occurred frequently in Norwegian oats recently. Early prediction of DON levels is important for farmers, authorities and the ... -
Yield and herbage quality from organic grass clover leys—a meta-analysis of Norwegian field trials
(Journal article; Peer reviewed, 2016-12)A meta-analysis based on experiments in organically cultivated grasslands in Norway was conducted to quantify the effects of management factors on herbage yield and feed quality. A dataset was collected that included 496 ... -
Phenology, flowering and yield performance of 13 diverse strawberry cultivars grown under Nordic field conditions
(Journal article; Peer reviewed, 2016-12-14)As part of an overall assessment of the commercial suitability of strawberry cultivars for the Nordic environment, we studied 13 diverse cultivars in an experimental field in South East Norway. Early-maturing cultivars ... -
Effect of combined seasonal coverage on northern production of strawberry (Fragaria ananassa Duch)
(Journal article; Peer reviewed, 2017)Two field trials with five strawberry cultivars planted on a woven black polyfibre ground cover sheet with or without translucent sheet plant coverage during winter and the growing season as combined treatments were started ... -
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 ... -
The Invasive Liriomyza huidobrensis (Diptera: Agromyzidae): Understanding Its Pest Status and Management Globally
(Journal article; Peer reviewed, 2017)Liriomyza huidobrensis (Blanchard) is native to South America but has expanded its range and invaded many regions of the world, primarily on flowers and to a lesser extent on horticultural product shipments. As a result ... -
Mapping of quantitative trait loci associated with resistance to net form net blotch (Pyrenophora teres f. teres) in a doubled haploid Norwegian barley population
(Journal article; Peer reviewed, 2017)Barley net blotch caused by the necrotrophic fungus Pyrenophora teres is a major barley disease in Norway. It can cause grain shriveling and yield losses, and resistance in currently grown cultivars is insufficient. In ... -
Redistributing Phosphorus in Animal Manure from a Livestock-Intensive Region to an Arable Region: Exploration of Environmental Consequences
(Journal article; Peer reviewed, 2017)Specialized agricultural production between regions has led to large regional differences in soil phosphorus (P) over time. Redistribution of surplus manure P from high livestock density regions to regions with arable ... -
The Influence of Local Governance: Effects on the Sustainability of Bioenergy Innovation
(Journal article; Peer reviewed, 2017)This paper deals with processes and outcomes of sustainable bioenergy development in Emilia Romagna. It draws on an on-going research project concerning inclusive innovation in forest-based bioenergy and biogas in Norway, ... -
Towards inclusive innovation praxis in forest-based bioenergy
(Journal article; Peer reviewed, 2017)In this paper, we apply grounded innovation platforms (GRIPs) as a tool for inclusive innovation in relation to forest-based bioenergy in Norway. We use cases studied in the Triple Bottom Line Outcomes for Bioenergy ... -
Major shifts in species' relative abundance in grassland mixtures alongside positive effects of species diversity in yield: a continental-scale experiment
(Journal article, 2017)1. Increased species diversity promotes ecosystem function; however, the dynamics of multi-speciesgrassland systems over time and their role in sustaining higher yields generated by increased diver-sity are still poorly ... -
A study of variance estimation methods for systematic spatial sampling
(Journal article; Peer reviewed, 2017)An undesirable property of systematic spatial sampling is that there is no known method allowing unbiased estimation of the uncertainty of statistical estimates from these surveys. A number of alternative variance estimation ...
