Høstskudd og toppskader i genetiske forsøk med gran; variasjon og sammenhenger med vekst og vekstrytme
(NIBIO Rapport;3(23) 2017, Research report, 2017-03-03)Grantrærne danner høstskudd dersom knoppene som dannes etter vekstavslutning, bryter på nytt samme sommer. Dette kan føre til skader og feil på stammen i form av gankvist og krok som gir redusert virkeskvalitet. Denne ... -
Ice melt-induced variations of structural and functional traits of the aquatic microbial community along an arctic river (Pasvik river, Norway)
(Peer reviewed; Journal article, 2021-08-22)The effects of climate change-induced ice melting on the microbial communities in different glacial-fed aquatic systems have been reported, but seasonal dynamics remain poorly investigated. In this study, the structural ... -
Identification and in silico characterization of novel and conserved microRNAs in methyl jasmonate-stimulated Scots Pine (Pinus sylvestris L.) needles
(Peer reviewed; Journal article, 2020-03-28)MicroRNAs (miRNAs) are non-protein coding RNAs of ~20–24 nucleotides in length that play an important role in many biological and metabolic processes, including the regulation of gene expression, plant growth and developmental ... -
Identifying old Norway spruce and Scots pine trees by morphological traits and site characteristics
(Peer reviewed; Journal article, 2021-11-05)Old trees are important for biodiversity, and the process of their identification is a critical process in their conservation. However, determining the tree age by core extraction, ring counts, and eventually, cross-dating ... -
Impact of non-native tree species in Europe on soil properties and biodiversity: a review
(Peer reviewed; Journal article, 2022-11-21)In the context of global change, the integration of non-native tree (NNT) species into European forestry is increasingly being discussed. The ecological consequences of increasing use or spread of NNTs in European forests ... -
The impact of rainforest area reduction in the Guineo-Congolian region on the tempo of diversification and habitat shifts in the Berlinia clade (Leguminosae)
(Peer reviewed; Journal article, 2020-09-29)Aim: The Guineo‐Congolian region in Africa constitutes the second largest area of tropical rainforest (TRF) in the world. It covered an estimated 15–22 million km2 during the late Miocene (55–11 Ma) and it has experienced ... -
Impacts of human disturbance on flight response and habitat use of red deer
(Peer reviewed; Journal article, 2022-11-09)Many wild animals perceive humans as predators, and human disturbance,especially in the form of hunting, triggers antipredatory behavior among prey.Yet, knowledge of how game species react to different types of human ... -
Importance of Surface Roughness for the Local Biogeophysical Effects of Deforestation
(Journal article; Peer reviewed, 2019-08-14)Deforestation influences surface properties such as surface roughness, resulting in changes in the surface energy balance and surface temperature. Recent studies suggest that the biogeophysical effects are dominated by ... -
Imprints of management history on hemiboreal forest ecosystems in the Baltic States
(Journal article; Peer reviewed, 2018-11-15)In the Baltic States region, anthropogenic disturbances at different temporal and spatial scales mostly determine dynamics and development phases of forest ecosystems. We reviewed the state and condition of hemiboreal ... -
Improved detection and identification of the sudden oak death pathogen Phytophthora ramorum and the Port Orford cedar root pathogen Phytophthora lateralis
(Journal article; Peer reviewed, 2019-04-22)Early detection provides the best way to prevent introduction and establishment of alien plant pathogens. Amplification of DNA by PCR has revolutionized the detection and monitoring of plant pathogens. Most of those assays ... -
Improving living biomass c-stock loss estimates by combining optical satellite, airborne laser scanning, and nfi data
(Peer reviewed; Journal article, 2021-02-16)Policy measures and management decisions aimed at enhancing the role of forests in mitigating climate change require reliable estimates of carbon (C)-stock dynamics in greenhouse gas inventories (GHGIs). The aim of this ... -
Individmerking i reindriften – muligheter og utfordringer
(NIBIO-rapport;6(157) 2020, Research report, 2020-12)Innføring av obligatorisk individmerking av tamrein i Norge ble vedtatt av Stortinget 13. juni 2019. NIBIO har i denne rapporten belyst hvilke merkemetoder for individmerking som finnes på markedet i dag og hvordan disse ... -
Inferring Surface Albedo Prediction Error Linked to Forest Structure at High Latitudes
(Journal article; Peer reviewed, 2018-05-17)Predicting the surface albedo of a forest of a given species composition or plant functional type is complicated by the wide range of structural attributes it may display. Accurate characterizations of forest structure are ... -
Influence of mechanical site preparation on regeneration success of planted conifers in clearcuts in Fennoscandia – a review
(Peer reviewed; Journal article, 2020-03-25)In the Nordic countries Finland, Norway and Sweden, the most common regeneration method is planting after clearcutting and, often, mechanical site preparation (MSP). The main focus of this study is to review quantitative ... -
Influence of Spatial Resolution on Snow Cover Dynamics for a Coastal and Mountainous Region at High Latitudes (Norway)
(Peer reviewed; Journal article, 2019-06-07)Climate models show that global warming will disproportionately influence high‐latitude regions and indicate drastic changes in, among others, seasonal snow cover. However, current continental and global simulations covering ... -
