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 male and female genitalia characters of the European species of Monochamus Dejean, 1821, are described and compared in detail for the first time. The sclerites inside the median phallomer (internal sac) of M. sutor (Linnaeus, 1758) and M. galloprovincialis (Olivier, 1795) differ from those of all other examined species, and appear to be the best characters to separate M. sutor from M. galloprovincialis. There are no differences between the male or female genitalia characters of M. sartor (Fabricius, 1787) and M. urussovi (Fischer von Waldheim, 1805). Thus, M. urussovi is regarded as a subspecies of M. sartor: M. sartor urussovi nov. stat. The present results also support that the previously considered subspecies M. galloprovincialis pistor (Germar, 1818) is a true junior synonym of M. galloprovincialis galloprovincialis. No sclerites occur inside the internal sac of M. saltuarius (Gebler, 1830). The internal sac of M. sartor sartor (Fabricius, 1787), M. sartor urussovi and M. impluviatus impluviatus (Motschulsky, 1859) are distinctly different from the other European species of Monochamus: there is an elongated tube (terminal segment) inside the internal sac containing two very small and weakly sclerotized plates in M. sartor sartor and M. sartor urussovi and a larger sclerite in M. impluviatus impluviatus. A key to the European species and subspecies of Monochamus, incorporating male genitalia characters, is provided.

Wood protection by means of electro pulsing Electric fields have been evaluated for the protection of wood against attack by wood-destroying fungi. We could show that a low-pulsed electric field (PLEOT) had an inhibiting effect on wood destroying fungi compared with the tested reference power sources alternating and direct current. The study examined the suitability of PLEOT for use in wood preservation and evaluated the use of different wood and fungi species, different wood dimensions, the use in ground contact, as well as the test setup in the laboratory and the installation of the technology in the field. Different wood species could be protected by means of PLEOT against degradation by white and brown rot. Additionally, the degradation of wood could be stopped after four weeks establishment of the fungi. The use of PLEOT in ground contact resulted in lower weight loss of PLEOT-protected samples compared with untreated samples.

The recent economic downturn severely affected the US forest sector from a macro-economic perspective but little is known about changes in firm-level performance. In this study we investigate the changes in financial, social and environmental performance of forest sector firms during a period approximately corresponding to the downturn. We also assess industry dynamism and industry’s view about social and environmental responsibility as a competitive tool. We conducted a national survey of wood, furniture and paper companies. Approximately sixty percent of our respondents reported a decline in financial performance during the downturn. With respect to social and environmental performance, customer oriented actions show mixed trends, employee matters remained somewhat unaltered, community engagement significantly decreased, and engagement in environmental activities significantly increased. Respondents view their operating business environment as highly dynamic and difficult and they do not view engagement in social and environmental responsibility activities leading to either financial or non-financial benefits.
