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.

A comparative qualitative study of Norwegian and Newfoundland inshore fisheries revealed that compliance with the state’s fisheries regulations was governed by a set of moral distinctions which were strikingly similar in the two cases. Violations of government regulations were followed by informal sanctions only in commercial fisheries. Illegal food fishery was generally accepted. A fisherman could also break the law in commercial fisheries without being met with significant sanctions provided that it was generally perceived to be the only way to ensure a necessary outcome. The empirical findings are connected to the moral meanings of money and food, and it is suggested that the economies of natural resource harvesters include two different moral spheres. One of these spheres is linked to subsistence, small-scale operations and local exchange, and is perceived as morally safe. The other sphere is connected with money, large-scale operations, and exchange with strangers, and is seen as morally perilous.

Trees cover over one-third of the world's land area and carry out about two-thirds of global photosynthesis. Coniferous forests cover 1.2 billion hectares of Alaska, Canada, Scandinavia, and Russia, and comprise one-fourth of the world's boreal and temperate forests. More than 50% of Scandinavia's land area consists of forests, mostly coniferous. Information about the molecular responses in trees to biotic and abiotic factors is therefore of great importance - both scientifically and practically.Transcript regulation in response to drought stress was investigated for Norway spruce (Picea abies) with microarrays including 1,700 cDNAs from 5 EST libraries from Pinus taeda and analyzed using the Expresso Microarray Management System.In order to verify the level of drought stress, we measured the physiological status of the plants. After four days of drought, chlorophyll fluorescence was reduced by 6% and after eight days by over 40 %, compared to the control. Hybridizations of spruce RNA to microarray slides was used to probe for changes in transcripts from two to eight days after watering stopped.Monitoring of transcript levels was accomplished by hybridizing spruce cDNA to the 1700 element microarrays. After two days of drought, circa 2 % of the transcripts in Norway spruce were significantly upregulated and 7 % were downregulated. At the end of the experiment after eight days of drought needle chlorophyll fluorescence was reduced by 40 % compared to the control, and 6 % of the transcripts were upregulated and 12 % of the transcripts were downregulated. Results from inductive logic programming are also presented.
