Prediction of enteric methane emissions by sheep using an intercontinental database
(Peer reviewed; Journal article, 2022-12-15)Enteric methane (CH4) emissions from sheep contribute to global greenhouse gas emissions from livestock. However, as already available for dairy and beef cattle, empirical models are needed to predict CH4 emissions from ... -
Prediction of forest canopy fuel parameters in managed boreal forests using multispectral and unispectral airborne laser scanning data and aerial images
(Peer reviewed; Journal article, 2020-09-08)This study evaluated the suitability of different airborne laser scanning (ALS) datasets for the prediction of forest canopy fuel parameters in managed boreal forests in Finland. The ALS data alternatives were leaf-off and ... -
Prediction of leaf Bloch disease risk in Norwegian spring wheat based on weather factors and host phenology
(Peer reviewed; Journal article, 2021-02-17)Leaf blotch diseases (LBD), such as Septoria nodorum bloch (Parastagnospora nodorum), Septoria tritici blotch (Zymoseptoria tritici) and Tan spot (Pyrenophora tritici-repentis) can cause severe yield losses (up to 50%) in ... -
Prediction of Sporulation and Germination by the Spider Mite Pathogenic Fungus Neozygites floridana (Neozygitomycetes: Neozygitales: Neozygitaceae) Based on Temperature, Humidity and Time
(Journal article; Peer reviewed, 2018-06-19)Neozygites floridana is a pathogenic fungus and natural enemy of the two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), which is an important polyphagous plant pest. The aim of this study was to reveal ... -
Preharvest application with calcium and maturity at harvest affects postharvest fungal fruit decay of European plum
(Peer reviewed; Journal article, 2023-02-09)The combination of preharvest treatments with calcium chloride and fungicides, and storage of maturity graded fruit were assessed in five European plum cultivars. At harvest, samples of fruit within a commercially suitable ... -
Prevalence and parasite load of nematodes and trematodes in an invasive slug and its susceptibility to a slug parasitic nematode compared to native gastropods
(Peer reviewed; Journal article, 2020-04-09)The invasive slug Arion vulgaris (Gastropoda: Arionidae) is an agricultural pest and serious nuisance in gardens of Central and Northern Europe. To investigate if the success of A.vulgaris in Norway can be attributed to a ... -
Primary Succession of Surface Active Beetles and Spiders in an Alpine Glacier Foreland, Central South Norway
(Journal article; Peer reviewed, 2012)Spiders and beetles were pitfall-trapped in the foreland of the receding Hardangerjøkulen glacier in central south Norway. At each of six sampling sites, ages 3 to 205 years, twenty traps covered the local variation in ... -
Priming of inducible defenses protects Norway spruce against tree-killing bark beetles
(Peer reviewed; Journal article, 2019-11-01)Plants can form an immunological memory known as defense priming, whereby exposure to a priming stimulus enables quicker or stronger response to subsequent attack by pests and pathogens. Such priming of inducible defenses ... -
Priming of marine macrophytes for enhanced restoration success and food security in future oceans
(Peer reviewed; Journal article, 2021-03-23)Marine macrophytes, including seagrasses and macroalgae, form the basis of diverse and productive coastal ecosystems that deliver important ecosystem services. Moreover, western countries increasingly recognize macroalgae, ... -
Probabilistic risk assessment of pesticides under future agricultural and climate scenarios using a bayesian network
(Peer reviewed; Journal article, 2022-09-15)The use of Bayesian networks (BN) for environmental risk assessment has increased in recent years as they offer a more transparent way to characterize risk and evaluate uncertainty than the traditional risk assessment ... -
A process-based model to forecast risk of potato late blight in Norway (The Nærstad model): model development, sensitivity analysis and Bayesian calibration
(Peer reviewed; Journal article, 2021-04-23)Late blight caused by Phytophthora infestans is a serious, worldwide disease on potato (Solanum tuberosum). Phytophthora infestans normally reproduces in a clonal manner, but in some areas, as the Nordic Countries, sexual ... -
Production Function and Farmers' Risk Aversion: A Certainty Equivalent-adjusted Production Function
(Peer reviewed; Journal article, 2023-06-08)Faced with risky yields and returns, risk-averse farmers require a premium to take risks. In this paper, we estimate individual farmers’ degrees of risk aversion to adjust for the risk premium in returns and to replace the ... -
Production methods for high yielding plants of everbearing strawberry in the Nordic climate
(Peer reviewed; Journal article, 2022-03-15)Environmental conditions during plant raising determine the yield potential of everbearing strawberries. We studied the effect of three rooting dates in the cultivars ‘Favori’ and ‘Murano’ in a greenhouse with 18 ℃ and ... -
Production of tetravalent dengue virus envelope protein domain III based antigens in lettuce chloroplasts and immunologic analysis for future oral vaccine development
(Journal article; Peer reviewed, 2018-12-22)Dengue fever is a mosquito (Aedes aegypti) ‐transmitted viral disease that is endemic in more than 125 countries around the world. There are four serotypes of the dengue virus (DENV 1‐4) and a safe and effective dengue ... -
Production Risk, Farmer Welfare, and Bt Corn in the Philippines
(Journal article; Peer reviewed, 2017-12)We determine the production risk effects and welfare implications of single-trait Bt corn adoption in the Philippines. We use a stochastic production function estimation approach that allows for examining the skewness ... -
