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.

I første omdrev av 3Q ble det utarbeidet årlige feltkontroll-rapporter, men det ble av økonomiske årsaker ikke prioritert å utarbeide en samlet rapport med totaldata fra hele Norge. Derfor presenterer vi ikke her en detaljert rapport over endringsdata fra 2. omdrev, med resultater på nivå 3 i tolkingsinstruksen. Derimot presenterer vi sammenlignbare resultater på nivå 2, og legger hovedvekt på tolkingsresultater fra de viktigste arealtypene i jordbrukets kulturlandskap, og de arealtypene som har vist seg spesielt vanskelig å tolke fra flybilder.....

The effect of four different growing locations from Stjørdal, Norway (63,36N) to Conthey, Switzerland (46,12N) on the composition of bioactives in strawberry /Fragaria x ananassa Duch.) of three genotypes (cvs Clery, Elsanta and Korona) was evaluated. Principal component analysis (PCA) was used to characterize differences in bioactives between genotype within a location. Despite harvest period and year-to-year effects, a clear clustering related to the effects of the cultivars was shown. Furthermoe, PCA was able to separate locations within a cultivar due to differences in bioactive compounds and this effect was stronger than the local variations by temporary weather changes or even year-to-year effects. As a result, the northern samples had principally lower anthocyanin amounts than the southern ones and, moreover, distribution of individual anthocyanins was different. In contrast, the content of vitamin C and the antioxidant capacity (TEAC, ORAC, total phenols) was generally increased with higher latitudes calculated on fresh weight basis. Results of proanthocyanidins and individual polyphenols detected by high performance liquid chromatography indicated that the higher contents were mainly due to tannin-related components. For all these observations, cultivars responded in general similarly. A north-South division was identified but no clear trend towards latitud could be recorded, mainly since major impact factor for the biosynthesis of phenolics and ascorbic acid is temperate, which is altering not only by latitude, but also by the shift of the harvest period and the current weather conditions prior to harvest. In conclusion, genetic effects were generally stronger than environmental effects.

During recent decades, forests have expanded into new areas throughout the whole of Norway. The processes explained as causing the forest expansion have focused mainly on climate or land use changes. To enable a spatially explicit separation of the effects following these two main drivers behind forest expansion, the authors set out to model the potential for natural forest regeneration following land use abandonment, given the present climatic conditions. The present forest distribution, a number of high-resolution land cover maps, and GIS methods were used to model the potential for natural forest regeneration. Furthermore, the results were tested with independent local models, explanatory variables and predictive modelling. The modelling results show that land use abandonment, in a long-term perspective, has the climatic and edaphic potential to cause natural forest regeneration of 48,800 km2, or 15.9% of mainland Norway. The future natural forest regeneration following land use change or abandonment can now be spatially separated from the effects of climate changes. The different independent model tests support the main findings, but small fractions of the modelled potential natural forest regeneration will probably be caused by other processes than land use abandonment.
