Re: [IUFRO RG 7.03 FORENT] Northern records of scolytids

Hi Malcolm, For the Lekander records, you may wish to contact Åke Lindelöw ake.lindelow@ekol.slu.se<mailto:ake.lindelow@ekol.slu.se> to see if he can access the records. You may also want to send an inquiry to Bengt Ehnström bengtaxel37@yahoo.se<mailto:bengtaxel37@yahoo.se>, now retired, but extremely knowledgeable about the beetle fauna of Scandinavia. You may be familiar with Arne C. Nilssen’s work on atmospheric and anthropomorphic long-range dispersal of scolytids in northern Norway. It isn’t really about established populations, but demonstrate the dispersal capability of these insects, which may be relevant with climate change. The two relevant publications that I am familiar with are: A. C. Nilssen, 1976: Sprednings- og etableringsevne hos phytofage barskogsbiller belyst ved undersøkelser i granplantefelter i Nord-Norge, in Cand. real. Thesis, University of Tromsø, pp. 116. (Dispersal and establishment of phytophagous bark beetles illuminated by research in spruce plantings in Northern Norway) A. C. Nilssen and J. Andersen, 1977: Funn av Coleoptera fra Nord-Norge. Norw. J. Ent. 24, pp. 7-9. (Records of Coleoptera from Northern Norway) Arne is now professor and senior curator in Tromsø, and can be contacted at arnec.nilssen@uit.no<mailto:arnec@imv.uit.no> Good luck, Staffan "Discovery consists of seeing what everybody has seen and thinking what nobody has thought" - Albert Szent-Gyorgyi *************************************** B.

Lekander et al. (1977) show map locations (not coordinates) of several tree-infesting scolytids of Norway that approximate the latitude of the Alaska collection. Lekander, B., B. Bejer-Petersen, E. Kangas, and A. Bakke. 1977. The distribution of bark beetles in the Nordic countries. Acta Ent. Fenn. 32: 1-37 + maps. Do you know who might provide the collection data of the scolytids shown on the maps in this reference? Or, do you know of the latitude of any scolytid elsewhere that rivals or exceeds the Alaska collection? Malcolm Furniss Moscow, Idaho, USA
