Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Stående volum er kubikkmassen av trærne i skogen og en av de mest sentrale variabler i de fleste skogregistreringer. I Norge har det de siste 90 årene vært en tredobling i stående volum, fra vel 300 millioner kubikkmeter uten bark i 1925 til nesten 1000 millioner kubikkmeter i 2014.

Since the decision to locate the main Norwegian air fighter base at Ørland, prolonged discussions of compensation to farmers for increased noise levels have taken place. This study is commissioned by the local authorities in order to describe how extra noise that impact living conditions on farms may also impact operating conditions, estate valuation and potential development for the farm entreprise. The study finds that a diversity of impacts may be expected since, in general, housing, residential environments and the farm enterprise form an interdependent set of assets. Removing or damaging one, will affect the integrated unity both near-term and longer-term.

Nitrogen-limited ecosystems are threatened by extensive spread of broom (Cytisus scoparius (L.) Link), a European leguminous shrub that is invasive in several countries. The establishment of invading species may, however, be suppressed by competition from native vegetation. The neighbor impact of the grass Festuca rubra subsp. commutata Gaudin on the performance of C. scoparius was studied in a greenhouse experiment with different arrival order, under low and high nitrogen supply, and with or without inoculation of nitrogen-fixing bacteria. Aboveground biomass of both species was measured after a six-months establishment period, and after a five-months regrowth period. In both periods, presence of F. rubra reduced the performance of C. scoparius as indicated by negative neighbor-effect intensity indices (NIntA). During the establishment period the competitive impact of F. rubra was highest, when planted before C. scoparius, followed by synchronous and late planting. Inoculation with rhizobia and low fertilization decreased the competitive impact of F. rubra. After cutting and regrowth priority effects of F. rubra were still visible. Interaction between the two study species was not affected anymore by inoculation, but strongly by fertilization, with highest competitive impact of F. rubra on C. scoparius under high nitrogen fertilization. In both study periods biomass of C. scoparius was negatively correlated with biomass of F. rubra. Our study provides knowledge about competition processes, which help to improve conservation and restoration measures regarding the spread of C. scoparius. Early sowing of a native grass can help to suppress the invasive species at an early stage. Competitive impact of the grass might be strengthened by high nitrogen availability.
