A carbon balance of Norway: terrestrial and aquatic carbon fluxes
(Journal article; Peer reviewed, 2015-02-07)Northernlandscapes accumulate carbon in vegetation and soils while rivers transport significant amounts of land-derived carbon to coastal areas. Here, we quantify carbon sources and sinks in main ecosystems (forests, ... -
A comparison of two methods of data collection for modelling productivity of harvesters: manual time study and follow-up study using on-board-computer stem records
(Journal article; Peer reviewed, 2018-04-13)Productivity of a mechanized P. patula cut-to-length harvesting operation was estimated and modelled using two methods of data collection: manual time study and follow-up study using StanForD stem files. The objective of ... -
A guideline for material comparisons using LCA
(NIBIO Rapport, Research report, 2023)The materials used in construction have a significant environmental impact and this is becoming more important as operational energy requirements continue to fall. It is therefore becoming increasingly important to take ... -
A sensible climate solution for the boreal forest
(Journal article; Peer reviewed, 2018-01-02)Climate change could increase fire risk across most of the managed boreal forest. Decreasing this risk by increasing the proportion of broad-leaved tree species is an overlooked mitigation–adaption strategy with multiple benefits. -
Above-ground biomass change estimation using national forest inventory data with Sentinel-2 and Landsat
(Peer reviewed; Journal article, 2021-08-25)This study aimed at estimating total forest above-ground net change (ΔAGB; Gg) over five years (2014–2019) based on model-assisted estimation utilizing freely available satellite imagery. The study was conducted for a ... -
The accuracy and precision of age determination by dental cementum annuli in four northern cervids
(Peer reviewed; Journal article, 2020-10-23)Individual age is an important element in models of population demographics, but the limitations of the methods used for age determination are not always clear. We used known-age data from moose (Alces alces), red deer ... -
Acetylation of Pinus radiata delays hydrolytic depolymerisation by the brown-rot fungus Rhondonia placenta
(Journal article; Peer reviewed, 2018-11-01)Acetylation of wood can provide protection against wood deteriorating fungi, but the exact degradation me- chanism remains unclear. The aim of this study was to determine the effect of acetylation of Pinus radiata wood ... -
Agricultural grasslands buffer density effects in red deer populations
(Peer reviewed; Journal article, 2022-12-29)Population densities of several cervid species have increased in recent decades in North America and Europe, and cervids frequently eat and damage agricultural crops. Competition and depletion of natural food resources are ... -
An automatic pre-processing method to detect and reject signal artifacts from full-shift field-work sEMG recordings of bilateral trapezius activity
(Journal article; Peer reviewed, 2019)Bipolar surface EMG (sEMG) signals of the trapezius muscles bilaterally were recorded continuously with a frequency of 800 Hz during full-shift field-work by a four-channel portable data logger. After recordings of 60 ... -
An enhanced forest classification scheme for modeling vegetation–climate interactions based on national forest inventory data
(Journal article; Peer reviewed, 2018-01-18)Forest management affects the distribution of tree species and the age class of a forest, shaping its overall structure and functioning and in turn the surface–atmosphere exchanges of mass, energy, and momentum. In order ... -
An inverse shortest path approach to find forwarder productivity functions
(Journal article; Peer reviewed, 2018-06-05)This paper presents an optimization model designed to find productivity functions for timber forwarding. Timber forwarding or skidding has for some 25 years been calculated using shortest path formulations on grid networks. ... -
Anaerobic digestion affecting nitrous oxide and methane emissions from the composting process
(Peer reviewed; Journal article, 2021-07-02)Composting and anaerobic digestion are the most common ways to treat organic residues. Sometimes the organic rest after anaerobic digestion is also composted. In this study we investigated greenhouse gas emissions from ... -
Analyse av skogstrukturer registrert i landsskogtakseringen – Sluttrapport fra prosjektet «Viktige strukturer i norsk skog»
(NIBIO Rapport;3(96) 2017, Research report, 2017-07-17)I denne rapporten gis en oversikt over hvordan skog med fleretasjet bestandsstruktur er fordelt innen like arealkategorier i norsk skog. Vi har også sammenstilt data for å belyse om sjiktning i skog overlapper med forekomst ... -
Analyse av størrelse, årsaker til og reduksjonsmuligheter for avskoging i Norge
(NIBIO Rapport;3(152) 2017, Research report, 2017-12-14)I henhold til det Norske klimagassregnskap leder avskoging til en betydelig del av de nasjonale klimagassutslipp. Målet med denne rapporten er en kartlegging av størrelse og årsaker til avskoging som kan forbedre forståelsen ... -
