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.

The Norwegian Institute for Agricultural and Environmental Research (BIOFORSK) - is a national R&D institute under the Norwegian Ministry of Agriculture and Food. Bioforsk is a new institute as a result of the merger of The Norwegian Centre for Soil and Environmental Research, The Norwegian Crop Research Institute and Norwegian Centre for Ecological Agriculture. The main areas of competence are linked to food quality and safety, agriculture and rural development, environmental protection and natural resources management. The R&D activities of Bioforsk are organized in seven research divisions, located in different regions of Norway. Bioforsk encompasses a wide range of competence within natural sciences, with long traditions in field and laboratory-based experimental studies. This includes also the development and application of a range of tools and models for management and policy support linked to agriculture and environment. During the last 2 years, the institute published 233 per-reviewed articles and is closed relation with Norwegian industrial partners and farmers. Bioforsk offers postgraduate training for Ph D students. BIOFORSK has a staff of about 450, with an annual turnover of EUR 40 millions. The new Bioforsk Nord Bodø (BNB) team is in charge of developing a new research strategy into the blue-green zone. BNB wish to arrange for researchers from different specialization (physiologists, biochemists, ecologists, molecular biologists and agronomists) to collaborate and conduct integrated research in the ecophysiology of coastal species. BNB aims to make available information that will assist coastal management but can also be the first step towards a future sustainable development of integrated aquaculture systems and organic farming. BNB is a dynamic research team that has its expertise in plant & growth physiology, phycology, microbiology and organic farming. Therefore, BNB has expertise in environmentally friendly production and organic farming techniques. For 2008-2011, BNB is involved in several projects concerning coastal plant biology, ecology and production. By participating in the "algesymposium 2008" graciously organized by the Norwegian Institute for Water Research (NIVA), BNB wishes to develop collaboration to increase knowledge on seaweeds cultivation, technologies related to seaweeds production and the use of seaweed in agriculture (bioactive feed additive "functional food", fertilizers), bioenergy and waste (water)treatment.

Prosjekt Arvesølv fikk i oppdrag fra Fylkesmannen i Vest-Agder å oppsøke 4 områder hvor grunneier hadde søkt om RMP- (Regionalt miljøprogram) midler til skjøtsel av artsrik slåtte- og beitemark. Følgende områder blei besøkt og vurdert: Stokke i Farsund kommune, Guddal og Liland i Sirdal kommune, Bjerland i Marnadal kommune og Bryggesåhommen i Hægebostad kommune. Denne rapporten oppsummerer feltregistreringene og gir råd for videre skjøtsel av biomangfoldverdiene.

Hisdal ligger i Setesdals Vesthei i nedre deler av Bykle kommune. Selve dalen går inn i øst ved Otra ved Hislii og strekker seg vestover mot Støyldalen og Hisvatnet.Under Hisdalsfjellet ligger det to fjellgårder på ca 650 m.o.h. Disse to gårdene kalles Hisdal, og det er det tidligere innmarksarealet rundt disse to gårdene som er utgangspunktet for denne registreringen.Det er et mål at stedegent kulturavhengig biomangfold på Hisdal skal bli ivaretatt og utviklet i årene framover. Denne rapporten legger opp til konkret restaurering og skjøtsel av avgrensede verdifulle biomangfoldlokaliteter, samt gir generelle skjøtselsråd for annet kulturmarksareal på Hisdal.

Commercial products sold as "Jumping beans" are seed capsules of the scrubs Sebastiana paovniana, S. palmeri or  S. bolcularis containing larvae of Cydia deshaisiana. The larva makes the capsule move when heated. The risk assessment concluded that the larvae depend on a host not present in Norway to complete its life cycle. As the host plants only grow under extreme hot, desert conditions the expected climatic changes in the foreseable future will not lead to establishment and spread of the pest.

Bursaphelenchus xyliphilus, the Pine Wood Nematode (PWN) is not known to occur in Norway. With the present trade pattern the probability of entry of PWN into Norway is high. The most probable pathway is wood packing material. The probability that PWN will establish and spread in Norway is high. The beetle Monochamus sutor is regarded as a potential vector, but this has not been established in nature. The currently low density may retard PWN, but it will probably not stop establishement in a longer perspective.

To understand mycotoxin accumulation and the infection cycle of the wheat head blight pathogen Fusarium graminearum sensu stricto,fungal gene expression profiles were monitored during plant infection. Strains containing mutations in genes for three transcription factors were found to control deoxynivalenol (DON) accumulation in planta and pathogenicity. Expression profiles were compared between wildtype and these mutants during infection of wheat. Mutants deleted for the StuA gene were greatly decreased in sporulation and produced no perithecia in culture. Unlike "stuA mutants in F. oxysporum, F. graminearum "stuA mutants were greatly reduced in pathogenicity. Reduced pathogenicity may be due to decreased DON levels in planta, which in the mutant were

The apple fruit moth (Argyresthia conjugella) is a serious pest in apples. It is a specialist seed predator of rowan, but the females will lay eggs on apples when rowan berries are scarce. Olfaction is important for many insect species in locating host plants. The odorant detection results from the association of odorous ligands with specific olfactory receptors, which are located in the membrane of the olfactory neurons. The aim of this work is to identify and characterize the odorant receptor genes and the genes involved in the regulation of the circadian olfactory response rhythm in the female apple fruit moth. In order to identify ORs, and other genes involved in olfaction, in the apple fruit moth a library of mRNA up-regulated in the antenna compared to the legs was made using subtractive hybridization. So far 37 of the clones containing sequences that were found to be up-regulated in the antenna, out of in total 1045 clones, have been sequenced. BLAST searches were performed (BLASTx and BLASTn) to try to identify the transcripts. Those sequences that did not give a useful hit in the blast searches were translated to protein sequences in all six reading frames and the possible protein sequences were investigated for the presence of trans-membrane domains. The blast searches yielded useful hits for most of the sequences. 20 sequences were assigned to be probable odorant binding proteins and these seem to represent 12 different genes. Seven sequences were assigned to be glutathione S-transferases and 1 sequence were assigned to be cytochrome P450. Seven sequences gave no useful hits in the blast searches. These sequences seemed to represent 4 different genes and 2 of these have were predicted to contain transmembrane domains. These are possible odorant receptors.
