DNA-overvåkning av brunbjørn i Karasjok 2019 ved bruk av hårfeller
(NIBIO Rapport;6(76) 2020, Research report, 2020-05)DNA-overvåkning av brunbjørn i et 400 km2 stort område nær Karasjok i Finnmark ble utført med hårfeller med luktstoff i 2 måneder fra juni til august i 2019. Vi brukte et 5 x 5 km rutesystem med 16 ruter med én hårfelle i ... -
Diplodia sapinea – en ny skadegjører på furu
(NIBIO POP;6(24) 2020, Journal article, 2020-05)Soppen Diplodia sapinea er en nylig oppdaget skadegjører på furu i Norge og andre nordiske land. Soppen kan skade både frø, småplanter og større trær. Soppen er relativt varmekjær og har tidligere stort sett gjort skade ... -
«Animal Sense» – elektronisk reinvarsling Lavkost-teknologi skal forhindre dyrepåkjørsler
(NIBIO POP;6(25) 2020, Journal article, 2020-05)Når vilt, tamrein og husdyr skal krysse vei og jernbane, skjer ikke det alltid med et lykkelig resultat. I Europa har dyrepåkjørsler økt de siste 40 årene. I tillegg til å være et alvorlig velferdsproblem for dyr og ... -
The taxonomic significance of ddRADseq based microsatellite markers in the closely related species of Heracleum (Apiaceae)
(Peer reviewed; Journal article, 2020-05-07)Many studies on Heracleum have shown poor correspondence between observed molecular clusters and established taxonomic classification amongst closely related species. This might reflect both unresolved taxonomy but perhaps ... -
A sensor-fusion-system for tracking sheep location and behaviour
(Peer reviewed; Journal article, 2020-05-13)The growing interest in precision livestock farming is prompted by a desire to understand the basic behavioural needs of the animals and optimize the contribution of each animal. The aim of this study was to develop a ... -
Subalpine fir (abies laciocarpa) and Norway spruce (picea abies) seedlings show different growth responses to blue light
(Peer reviewed; Journal article, 2020-05-15)Blue light (BL) affects different growth parameters, but information about the physiological effects of BL on conifer seedlings is limited. In northern areas, conifer seedlings are commonly produced in heated nursery ... -
An extension to: Systematic assessment of commercially available low-input miRNA library preparation kits
(Peer reviewed; Journal article, 2020-05-21)High-throughput sequencing has emerged as the favoured method to study microRNA (miRNA) expression, but biases introduced during library preparation have been reported. We recently compared the performance (sensitivity, ... -
An annotated checklist of bryophytes of Europe, Macaronesia and Cyprus
(Peer reviewed; Journal article, 2020-05-28)Introduction. Following on from work on the European bryophyte Red List, the taxonomically and nomenclaturally updated spreadsheets used for that project have been expanded into a new checklist for the bryophytes of Europe. ... -
Hyperspectral NIR time series imaging used as a new method for estimating the moisture content dynamics of thermally modified Scots pine
(Peer reviewed; Journal article, 2020-06-04)The purpose of this research is to develop a method for estimating the spatially and temporally resolved moisture content of thermally modified Scots pine (Pinus sylvestris) using remote sensing. Hyperspectral time series ... -
A stand-level growth and yield model for thinned and unthinned managed Norway spruce forests in Norway
(Peer reviewed; Journal article, 2020-06-05)A new stand-level growth and yield model, consisting of component equations for stand volume, basal area, survival, and dominant stand height, was developed from a dataset of long-term trials for managed thinned and unthinned ... -
Leachability and Decay Resistance of Wood Polyesterified with Sorbitol and Citric Acid
(Peer reviewed; Journal article, 2020-06-06)Research Highlights: Polyesterification of wood with sorbitol and citric acid (SCA) increases decay resistance against brown-rot and white-rot fungi without reducing cell wall moisture content but the SCA polymer is susceptible ... -
A simple grid-based framework for simulating forest structural trajectories linked to transient forest management scenarios in Fennoscandia
(Peer reviewed; Journal article, 2020-06-16)Forest structural properties largely govern surface fluxes of moisture, energy, and momentum that strongly affect regional climate and hydrology. Forest structural properties are greatly shaped by forest management activities, ... -
Efficiency drivers in harvesting operations in mixed Boreal stands: a Norwegian case study
(Peer reviewed; Journal article, 2020-06-17)This paper uses Data Envelopment Analysis (DEA) to evaluate how the technical efficiency of forest harvesting operations is influenced by terrain conditions and forest attributes, in addition to exploring the existence of ... -
Evaluating the terrestrial carbon dioxide removal potential of improved forest management and accelerated forest conversion in Norway
(Peer reviewed; Journal article, 2020-06-19)As a carbon dioxide removal measure, the Norwegian government is currently considering a policy of large-scale planting of spruce (Picea abies (L) H. Karst) on lands in various states of natural transition to a forest ... -
A chlorophyll-deficient, highly reflective soybean mutant: radiative forcing and yield gaps
(Peer reviewed; Journal article, 2020-06-22)Sunlight absorbed at the Earth’s surface is re-emitted as longwave radiation. Increasing atmospheric concentrations of CO2 and other greenhouse gases trap an increasing fraction of such heat, leading to global climate ... -
