Establishment of a piscine myocarditis virus (PMCV) challenge model and testing of a plant-produced subunit vaccine candidate against cardiomyopathy syndrome (CMS) in Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2021-08-30)Cardiomyopathy syndrome (CMS) is a severe cardiac disease occurring in the grow-out sea phase of farmed Atlantic salmon with approximately 100 outbreaks annually in Norway. Piscine myocarditis virus (PMCV) is believed to ... -
Estimating and managing broad risk of chronic wasting disease spillover among cervid species
(Peer reviewed; Journal article, 2023-09-10)The management of infectious wildlife diseases often involves tackling pathogens that infect multiple host species. Chronic wasting disease (CWD) is a prion disease that can infect most cervid species. CWD was detected in ... -
Estimating Carbon Sink Strength of Norway Spruce Forests Using Machine Learning
(Peer reviewed; Journal article, 2022-10-19)Forests sequester atmospheric carbon dioxide (CO2) which is important for climate mitigation. Net ecosystem production (NEP) varies significantly across forests in different regions depending on the dominant tree species, ... -
Estimating local-scale forest GPP in Northern Europe using Sentinel-2: Model comparisons with LUE, APAR, the plant phenology index, and a light response function
(Peer reviewed; Journal article, 2023-01-03)Northern forest ecosystems make up an important part of the global carbon cycle. Hence, monitoring local-scale gross primary production (GPP) of Northern forest is essential for understanding climatic change impacts on ... -
Estimating stand level stem diameter distribution utilizing harvester data and airborne laser scanning
(Journal article; Peer reviewed, 2019-08-07)Accurately positioned single-tree data obtained from a cut-to-length harvester were used as training harvester plot data for k-nearest neighbor (k-nn) stem diameter distribution modelling applying airborne laser scanning ... -
Estimating the Permeability of Naturally Structured Soil From Percolation Theory and Pore Space Characteristics Imaged by X-Ray
(Journal article; Peer reviewed, 2018-10-30)The saturated hydraulic conductivity of soil, Ks, is a critical parameter in hydrological models that remains notoriously difficult to predict. In this study, we test the capability of a model based on percolation theory ... -
Estimating unconsolidated sediment cover thickness by using the horizontal distance to a bedrock outcrop as secondary information
(Journal article; Peer reviewed, 2017)Unconsolidated sediment cover thickness (D) above bedrock was estimated by using a publicly available well database from Norway, GRANADA. General challenges associated with such databases typically involve clustering and ... -
Estimation of Forest Growing Stock Volume with UAV Laser Scanning Data: Can It Be Done without Field Data?
(Peer reviewed; Journal article, 2020-04-14)Laser scanning data from unmanned aerial vehicles (UAV-LS) offer new opportunities to estimate forest growing stock volume ( V ) exclusively based on the UAV-LS data. We propose a method to measure tree attributes and using ... -
Estimation of phosphorus-based flame retardant in wood by hyperspectral imaging—a new method
(Journal article; Peer reviewed, 2018-02-15)It is recognised that flame retardant chemicals degrade and leach out of flame-protected wood claddings when exposed to natural weathering. However, the ability to survey the current state of a flame retardant treatment ... -
The Ethiopian staple food crop enset (Ensete ventricosum) assessed for the first time for resistance against the root-lesion nematode Pratylenchus goodeyi
(Peer reviewed; Journal article, 2021-02-08)Pratylenchus goodeyi appears to be the most prevalent nematode pest of enset in Ethiopia, where it can occur in extremely high densities. However, the damage to yield or how different enset cultivars react to the nematode ... -
Ethnic Variation in Immigrants’ Diets and Food Acculturation – United States 1999–2012
(Peer reviewed; Journal article, 2020-07-24)Immigration has changed the United States from having a predominantly white to a more ethnically diverse population. People who move to the U.S. may initially have diets unlike native-born Americans but gradually adopt ... -
European Agriculture after Brexit: Does Anyone Benefit from the Divorce?
(Peer reviewed; Journal article, 2020-08-30)The UK exited the EU on 31 January 2020, with a transition period agreed as part of the Withdrawal Agreement. During this transition period the UK and the EU will decide on their future trading relationship. No matter what ... -
A European map of groundwater pH and calcium
(Peer reviewed; Journal article, 2021-03-17)Water resources and associated ecosystems are becoming highly endangered due to ongoing global environmental changes. Spatial ecological modelling is a promising toolbox for understanding the past, present and future ... -
European mushroom assemblages are darker in cold climates
(Peer reviewed; Journal article, 2019-10-10)Thermal melanism theory states that dark-colored ectotherm organisms are at an advantage at low temperature due to increased warming. This theory is generally supported for ectotherm animals, however, the function of colors ... -
European-wide forest monitoring substantiate the neccessity for a joint conservation strategy to rescue European ash species (Fraxinus spp.)
(Peer reviewed; Journal article, 2022-03-19)European ash (Fraxinus excelsior) and narrow-leafed ash (F. angustifolia) are keystone forest tree species with a broad ecological amplitude and significant economic importance. Besides global warming both species are ... -
