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.

Tørket rekeskall i form av pulver (rekemel) og pellets er undersøkt. Begge formuleringene gir god forsyning av nitrogen, fosfor, kalsium og magnesium i forsøk med potet. Kalium må suppleres. Utnyttelsesgraden er god også ved lave temperaurer. Pulver gir raskere virkning enn pellets, men pellets er mer anvendelig i praktisk gjødsling og vurderes som det mest aktuelle kommersielle produktet. Det var et potensielt større N-tap i form av lystgass fra pellets enn for pulver. Resultatene var sprikende med hensyn til virkning mot flatskurv og andre skurvtyper og gir ikke grunnlag for entydig konklusjon om sjukdomshemmende virkning i potet.

Organohalogen contaminants (OHCs) may affect various physiological parameters in birds including blood chemistry. We therefore examined blood plasma clinical-chemical parameters and OHCs in golden eagle, white-tailed eagle and goshawk chicks from Northern Norway. Correlation analyses on pooled data showed that alkaline phosphatase(ALKP), glucose and creatinine were significantly negatively correlated to various OHCs (all: po0.05; r: 0.43to 0.55; n=23), while alanine aminotransferase(ALAT), total protein, cholesterol, uric acid, total bilirubin, ratios protein:creatinine and uric acid:creatinine were significantly positively correlated to various OHCs (all: po0.05; r: 0.43- 0.96). Based on these relationships, we suggest that the OHC concentrations found in certain raptor chicks of Northern Scandinavia may impact blood plasma biochemistry in a way that indicates impacts on liver, kidney, bone, endocrinology and metabolism. In orderto elaborate further on these relationships and mechanisms, we recommend that a larger study should take place in the near future.

Organohalogen contaminants (OHCs) may affect various physiological parameters in birds including blood chemistry. We therefore examined blood plasma clinical-chemical parameters and OHCs in golden eagle, white-tailed eagle and goshawk chicks from Northern Norway. Correlation analyses on pooled data showed that alkaline phosphatase (ALKP), glucose and creatinine were significantly negatively correlated to various OHCs (all: p<0.05; r: -0.43 to -0.55; n=23), while alanine aminotransferase (ALAT), total protein, cholesterol, uric acid, total bilirubin, ratios protein:creatinine and uric acid:creatinine were significantly positively correlated to various OHCs (all: p<0.05; r: 0.43-0.96). Based on these relationships, we suggest that the OHC concentrations found in certain raptor chicks of Northern Scandinavia may impact blood plasma biochemistry in a way that indicates impacts on liver, kidney, bone, endocrinology and metabolism.

The use of rented land has increased steadily over time in Northern Norway. At the same time there is a common perception that there is an increased regrowth of agricultural land. In this paper we investigate if the use of rented land also is a factor that leads to increased re-growth. We utilize land use data from the 3Q project in Northern Norway. These data are combined with data from the applications for acreage support to divide areas on tree types of properties. The area of abandoned land is explained as a function of property types. Our results show that there is a significant difference between owner used and rented land with respect to the amount of abandoned land on the property. This suggests that when previous farmers have rented out their land, one third of the previously farmed land may have been taken out of productions, and is now identified as abandoned land.
