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.

Et `multifunksjonelt` jordbruk produserer, i tillegg til mat, en rekke fellesgoder slik som landskap som er tilgjengelige og attraktive for turisme, reiseliv, rekreasjon og friluftsliv. Jordbruk kan også være viktig for det biologiske mangfoldet og Direktoratet for naturforvaltning rapporterer at vel 30 % av artene på den såkalte `Rødlista` (arter som anses å være truet eller sårbare) er knyttet til jordbrukslandskap. Å ivareta mange ulike funksjoner innenfor ett areal krever i beste fall en balansegang, i verste fall skapes det dyptgripende konflikter. Et viktig spørsmål i den forbindelse er om disse funksjonene best kan ivaretas gjennom bruk eller vern av jordbrukslandskapet.

Svarthjorten kan regnes til de artene som kalles urskogsarter. De krever ikke urskog i strengeste forstand, men at skogen har noen av de samme egenskapene. Gamle grove graner som kan ligge og brytes ned over lang tid er en viktig faktor for denne sjeldne billen.

Mange skadeinsekter har liten betydning som skadegjørere ute i skogen. Noen av disse kan imidlertid gjøre stor skade når de opptrer på nyplantede trær i parker og alléer. I mange treplantinger brukes litt større trær, og jo større de er, jo høyere er risikoen for at de blir angrepet av skadeinsekter allerede i planteskolen. Planteskolene og mottakskontrollen bør derfor være svært nøye med å undersøke trærne før utplanting. Dette er særlig viktig ved import.

Mange problemer kan oppstå når trær blir plantet i grøntanlegg langs veier. Nye eller mer ukjente skader kan oppstå, men også gamle, velkjente skadegjørere kan blomstre opp.I en bjørkeallé i Spydeberg plantet høsten 2004 har en praktbille [Agrilus viridis (Linnaeus, 1758)] forårsaket store skader.

Over the last decades the forestry sciences have been opened for new topics and methods. In addition to traditional forestry topics they have participated in environmental and ecosystem research. So far this type of research has been perceived as “applied”. From the modelling perspective there has been a misunderstanding among the participating disciplines of the character of knowledge being applied. Here we introduce two types of models of forest utilization and discuss their possibilities and limits for forestry sciences. The first perspective of forests is the one dominating in modelling today and in forestry sciences. It has been adopted from physics. The second perspective of forests has implicitly been adopted in the past for pragmatic reasons.

In recent years several forest insects have been recorded as newcomers or as more abundant than before towards northern latitudes and higher elevations in Norway. Such observations are from different groups of forest insect, including herbivorous geometrids, phloeophagous bark beetles and insects in cone seed .......

Moisture content, volatile in nature, is an important trait for any timber customer. Commercial board samples were observed to yield formulas for EMC reduction by kiln temperature, for hysteresis by board length, and for MC sorption dynamics by temperature. Industrial kiln practice lowers the EMC to approximately 95% of tabulated values. In this work, hysteresis was verified, and the most significant impact in natural ambient is that moisture migration to the board center appears to catch up with surface adsorption, reducing the influence of temperature and surface resistance. A concluding procedure for estimating MC dynamics for timber boards on stickers is outlined.

Rural communities in Norway have been under great economic stress in recent years. There has been an increasing debate about how to utilize the large potential in a growing tourism industry to promote rural employment and income. This study is based on the institutional view of innovation with a focus on institutions that are important for stimulating innovations. The objectives are: 1) to determine if networking is positively related to innovativeness and if innovativeness is positively related to performance in the nature-based tourism industry in Norway and 2) to develop an in-depth understanding of how different actors trigger a member of the industry to change, create, or otherwise innovate. An email survey was conducted of companies across the country followed by a qualitative study in one Norwegian municipality. Results indicate that there is a positive connection between networking and innovativeness, and between innovativeness and performance. A qualitative case example illustrates the interaction among actors and the resulting impacts on the innovation process.

An international EU/Interreg III Kolarctic project `Development and implementation of an environmental monitoring and assessment program in the joint Finnish, Norwegian and Russian border area`, was carried out during 2003–2006 as a joint undertaking between Norwegian, Finnish and Russian research institutes and environmental authorities. The aim of the terrestrial ecosystem sub-project of the Pasvik project was to develop and implement a monitoring and assessment programme for terrestrial ecosystems in the joint Finnish, Norwegian and Russian border area...
