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.

Rapporten inneholder revidering av to skjøtselsplaner for verdifull slåttemark i Sollia, Ørskog kommune; BN00079373 Vagsvika: Sollia, austre del og BN00079372 Vagsvika: Sollia – øvre Begge lokalitetene innehar verdi A som følge av arealstørrelse, tilstand og artsmangfold. Slåttemarkene utgjør også habitat for rødlistearten solblom (VU – Sårbar). Det er avgjørende med en videreføring av tradisjonell ekstensiv skjøtsel for å kunne opprettholde verdien på disse slåttemarkene.

Hvert år produseres i snitt 300 liter melk per innbygger i Norge. Vi beregnet summen av all energi som brukes både direkte og indirekte for å produsere melk for 20 gårder med melkeku i Møre og Romsdal. Resultatet viser at energibehovet varierer mye og tyder på at mange kunne spare både mye energi og en del utgifter.

Nibio og SSB har gjennom tidligere undersøkelser vist at ti prosent av landets store utmarkseiendommer mangler eiendomsgrenser og eier i det nasjonale eiendomsregisteret. Til sammen utgjør disse eiendommene rundt en femdel av Norges landareal. Tall fra Kartverket viser at fundamentale opplysninger som gårds- og bruksnummer mangler for om lag 3,5 prosent av landets 2,6 millioner eiendomsteiger i form av grunneiendommer og festegrunn.

Vannområde Glomma og Grensevassdragene utgjør et areal på nesten 30 000 km2. Som grunnlag for arbeidet med tiltaksplanlegging er det behov for å definere en del mindre tiltaksområder som skal ha særlig fokus. Inndelingen er basert på analyse av data om sårbare vannforekomster og tilførsler fra fulldyrket mark, husdyrhold, avløp i spredt bebyggelse og/eller gruvevirksomhet. Datagrunnlaget er hentet fra digitale kart og registre. Resultatet fra prosjektet er digitale kart over 8 tiltaksområder. Disse er også koblet til tiltaksdatabasen i rapporteringsverktøyet Glommadata.

BACKGROUND: In the past few years, much effort has been invested into developing a new blue economy based on harvesting, cultivating and processing marine macroalgae in Norway. Macroalgae have high potential for a wide range of applications, e.g. as source of pharmaceuticals, production of biofuels or as food and feed. However, data on the chemical composition of macroalgae from Norwegian waters are scant. This study was designed to characterize the chemical composition of 21 algal species. Both macro- and micronutrients were analysed. Concentrations of heavy metals and the metalloid arsenic in the algae were also quantified. RESULTS: The results confirm that marine macroalgae contain nutrients which are relevant for both human and animal nutrition, the concentrations whereof are highly dependent on species. Although heavy metals and arsenic were detected in the algae studied, concentrations were mostly below maximum allowed levels set by food and feed legislation in the EU. CONCLUSION: This study provides chemical data on a wide range of algal species covering the three taxonomic groups (brown, red and green algae) and discusses both benefits of and potential limitations to their use for food and feed purposes.

We investigated climatic trends in two contrasting locations in Europe at a regional level and at two specific sites, and we analysed how these trends are associated with the dry matter yield (DMY) of agriculturally improved grasslands. Trends of different meteorological variables were evaluated for Wielkopolska province, central Poland (1985-2014) and Troms county, northern Norway (1989-2015), as well as for two research stations located in these regions. Significant trends of increased mean air temperatures annually, and in April, June, July, August and November were identified both at the regional and site levels in Wielkopolska. In addition, growing degree days were increasing in Wielkopolska. In Troms, the common trends for the region and site studied were increase in mean air temperature in May and decrease in January. Grassland DMY was subsequently regressed against those meteorological variables for which significant trends were detected. In the Wielkopolska region, yields were negatively associated with the increase in air temperature in June, August, and the annual air temperature. The last relationship was also detected at the site level. We did not find any significant effects of climate trends on grassland DMY in the Norwegian study site or region.

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 to attribute climate effects to anthropogenic activities like forest management, good accounts of forest structure are necessary. Here, using Fennoscandia as a case study, we make use of Fennoscandic National Forest Inventory (NFI) data to systematically classify forest cover into groups of similar aboveground forest structure. An enhanced forest classification scheme and related lookup table (LUT) of key forest structural attributes (i.e., maximum growing season leaf area index (LAImax), basal-area-weighted mean tree height, tree crown length, and total stem volume) was developed, and the classification was applied for multisource NFI (MSNFI) maps from Norway, Sweden, and Finland. To provide a complete surface representation, our product was integrated with the European Space Agency Climate Change Initiative Land Cover (ESA CCI LC) map of present day land cover (v.2.0.7). Comparison of the ESA LC and our enhanced LC products (https://doi.org/10.21350/7zZEy5w3) showed that forest extent notably (κ = 0.55, accuracy 0.64) differed between the two products. To demonstrate the potential of our enhanced LC product to improve the description of the maximum growing season LAI (LAImax) of managed forests in Fennoscandia, we compared our LAImax map with reference LAImax maps created using the ESA LC product (and related cross-walking table) and PFT-dependent LAImax values used in three leading land models. Comparison of the LAImax maps showed that our product provides a spatially more realistic description of LAImax in managed Fennoscandian forests compared to reference maps. This study presents an approach to account for the transient nature of forest structural attributes due to human intervention in different land models.
