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.

NoFence is a virtual fencing system with the aim of finding a solution to the problems with keeping animals within a predefined when physical fences not are an option. The system consists of a collar based on GPS technology. When an animal wearing an activated collar crosses a predefined border, a sound signal will be given. If the animals then turns and walks back into the grazing area, the sound signal will stop. If the animal instead continue to walk over the border, the collar will give the animals an electric correction through two electrodes placed on the neck of the animal. Bioforsk Økologisk was hired to perform an independent evaluation about the welfare situation among animals on NoFence pastures. The aim with the trials 2012 was hence to do a first evaluation if/how NoFence affects sheep welfare and how quick the animals can learn the system.

Aspen trees are exposed to a range of attackers and employ varied strategies to reduce their impact. The diversity of responses may have importance for resistance properties at the stand level, and justifies the search for varied defensive strategies in natural populations. We used transcriptomic tools to evaluate diverse responses at the gene activity level in Populus tremula in response to wounding, and to inoculation with two pathogenic fungi (Melampsora magnusiana vs Ceratocystis sp.) that differ in life style (biotroph vs necrotroph) and host tissue requirement (live leaf vs dead wood tissues). Two aspen genotypes from the SwAsp collection with differences in growth and phenolic composition were used to study differences in resistance properties. High defence gene induction, high growth and elevated defence properties toward the biotroph appeared to support each other in this study exemplified in the more resistant SwAsp clone, whereas the more susceptible SwAsp clone was much less responsive to infections, and displayed more symptoms when infected with M. magnusiana. Interestingly, in the more resistant clone wounding gave greater systemic activity of selected candidate genes than when combined with the necrotroph, suggesting that this pathogen has some ability to suppress the induction or translocation of the systemic defence signal in this particular clone.
