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 shelf life of plum fruit (Prunus domestica) is limited due to among other factors fungal fruit decay. Absorbent pads (“fruit pads”) are commercially used today in order to absorb juice from the berries and condense water and hence reduce fungal growth. The aim of this experiment was to evaluate the effect of different types of absorbent pads on weight loss, decay and quality for plum fruit under realistic storage conditions. Plum fruit (‘Reeves’ and ‘Jubileum’) were delivered at a commercial packing house, packed in trays on a flow packaging machine with three different types of absorbent pads placed at the bottom of the trays (standard fruit pad and two humidity control pads with different active compounds; denoted active pad 1 and 2). Trays without pads were controls. After packaging, plums were stored at 3 or 6°C for 7 days and thereafter 2 days at 20°C. Fruit quality, weight loss and amount of fungal decay were recorded at the end of the storage period. The different pads had no significant effects on ripeness state measured by DA-meter and fruit firmness measured at end of storage. The pads had significantly different effect on weight loss, and for ‘Jubileum’ the weight loss was 1.5% for the active pad 1, 2.5% for the active pad 2 and below 1% for the standard pad and the control. Significant effects were found for cultivar and absorbent pads on the total amount of decayed fruit. ‘Jubileum’ was more vulnerable to decay than ‘Reeves’, and the active pad 2 had the lowest number of decayed ‘Jubileum’ fruit stored at 3°C. More work and a cost-benefit analysis should be performed before absorbent pads are recommended for plum fruit.

I 2014 ble det for sjette år på rad samlet inn prøver med antatt opphav fra brunbjørn (Ursus arctos) gjennom det nasjonale overvåkingsprogrammet for rovvilt i Norge. Det ble samlet inn 962 prøver i 2014 (703 ekskrementprøver, 247 hårprøver, 11 vevsprøver og 1 blodprøve), noe som er betydelig lavere antall prøver enn forrige år (1246 prøver i 2013). Av disse prøvene var 60 % positive for brunbjørn, og det ble påvist 136 ulike bjørner, hvorav 54 hunnbjørner og 82 hannbjørner. Dette er en reduksjon sammenlignet med forrige år da det ble påvist 55 hunnbjørner og 93 hannbjørner. I løpet av de siste seks årene har andelen hunnbjørner økt, og i 2014 var andelen økt til 40 %. Beregninger av antall ynglinger i samme periode ligger relativt stabilt på ca. 6 ynglinger. Som tidligere år er forekomsten av brunbjørn i hovedsak konsentrert i fylkene Hedmark (43), Finnmark (34) og Nord-Trøndelag (29). Av de 136 individbestemte bjørnene i Norge i 2014 var 93 individer (68 %) tidligere påvist i Norge, noe som utgjør omtrent samme gjenfunnsandel som forrige år.

Graue Energie bezeichnet die Energiemenge, die nötig ist, um Produkte herzustellen und zu transportieren. Die Menge der Grauen Energie in Kuhställen trägt in Dänemark mit etwa 10 % zum gesamten Energiebedarf in der Milchviehproduktion bei (Dalgaard et al. 2000), in der Schweiz mit 32 % (Rossier und Gaillard 2004). Wir stellen hier eine Methode vor, um die Graue Energie (embodied energy) in der Gebäudehülle in landwirtschaftlichen Gebäuden vereinfacht zu berechnen. Unsere Ergebnisse zeigen, dass die Graue Energie pro Stallplatz in der Milchkuhhaltung sehr variiert und wesentlich von Grundfläche, Wandfläche und den verwendeten Materialien abhängt.
