Outline of Final Research Achievements

Fossil insects were found from geological strata of Last Glacial Maximum. Distributions of the extant beetle species are investigated at alpine zones in Japan and in Alaska. To analyze the paleoclimate, data at climatic stations in East Asia and Alaska are gathered using internet. Many beetle specimens in Osaka Museum of Natural History are identified newly, and the dissected specimens for comparison with fossils are produced. The low temperature at the Last Glacial period in Nojiriko, Nagano Pref. is numerically shown. The beetle assemblage at Last Glacial Maximum in Tsugaru, Aomori Pref. is summarized to a report.
