Stand-level mortality models for nordic boreal forests
(Peer reviewed; Journal article, 2020-12-01)New mortality models were developed for the purpose of improving long-term growth and yield simulations in Finland, Norway, and Sweden and were based on permanent national forest inventory plots from Sweden and Norway. ... -
The relationship between volume increment and stand density in Norway spruce plantations
(Peer reviewed; Journal article, 2020-06-29)An understanding of the relationship between volume increment and stand density (basal area, stand density index, etc.) is of utmost importance for properly managing stand density to achieve specific management objectives. ... -
Parasitoids indicate major climate-induced shifts in arctic communities
(Peer reviewed; Journal article, 2020-09-11)Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid ... -

(NIBIO-rapport;6(178)2020, Research report, 2020-12)Sør-Varanger kommune i Øst-Finnmark har vært utsatt for luftforurensning fra russisk smelteverksindustri siden 1930-tallet, særlig fra smelteverket i byen Nikel som ligger bare ca. 10 km øst for den norske-russiske grensen ... -
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 ... -
Using Red List species in designating protection status to forest areas: a case study on the problem of spatio-temporal dynamics
(Peer reviewed; Journal article, 2020-08-12)Red-listed species are often used as target species in selection of sites for conservation. However, limitations to their use have been pointed out, and here we address the problem of expected high spatio-temporal dynamics ... -
Predicting Aggregate Degradation in Forest Roads in Northwest Oregon
(Peer reviewed; Journal article, 2020-07-03)In the Pacific Northwest, forest roads have the potential to cause significant environmental degradation, especially to water resources due to increased sediment production. The goal of this research is to improve the ... -
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 ... -
Genetic characterization of a small closed island population of Norwegian coastal goat
(Peer reviewed; Journal article, 2020-02-24)The Norwegian coastal goat is a national and endangered breed. Coastal goat populations are mainly divided with a large mainland and two small island populations. The objective of this study is to describe genetic diversity ... -
Fungal attack on archaeological wooden artefacts in the Arctic—implications in a changing climate
(Peer reviewed; Journal article, 2020-09-03)Climate change is expected to accelerate the microbial degradation of the many extraordinary well-preserved organic archaeological deposits found in the Arctic. This could potentially lead to a major loss of wooden artefacts ... -
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 ... -
How much water can wood cell walls hold? A triangulation approach to determine the maximum cell wall moisture content
(Peer reviewed; Journal article, 2020-08-31)Wood is a porous, hygroscopic material with engineering properties that depend significantly on the amount of water (moisture) in the material. Water in wood can be present in both cell walls and the porous void-structure ... -
Quantifying regional surface energy responses to forest structural change in Nordic Fennoscandia
(Peer reviewed; Journal article, 2020-07-16)In a climate model, surface energy and water fluxes of the vegetated ecosystem largely depend on important structural attributes like leaf area index and canopy height. For forests, management can greatly alter these ... -
Hot water and cutting for control of Impatiens glandulifera
(Peer reviewed; Journal article, 2020-03-31)Ornamental jewelweed (Impatiens glandulifera Royle) is an alien invasive plant in Europe. This annual plant often grows in riparian habitats where herbicides are prohibited. Several studies have reported the negative effect ... -
Governing dual objectives within single policy mixes: an empirical analysis of large carnivore policies in six European countries
(Peer reviewed; Journal article, 2020-11-03)Policy mixes (i.e. the total structure of policy processes, strategies, and instruments) are complex constructs that can quickly become incoherent, inconsistent, and incomprehensive. This is amplified when the policy mix ... -
A common Nordic-Baltic costing framework for road, rail and sea transport of roundwood
(NIBIO-rapport;7(8) 2021, Research report, 2021-01)Transport cost calculations are fundamental for most types of transport research. Applications can range from estimating the cost benefits of developing transport technologies (e.g. increased truck GVWs) to comparing ... -
