Outline of Final Research Achievements

At a total of 63 localities in Tohoku area, Japan, we researched littoral beetle fauna before and after Tsunami by the Great East Japan Earthquake. We compared the number of individual of the littoral beetles and the level degree of environmental damages by Tsunami at 24 localities. (1) Serious damaged environment of seashore areas: almost littoral beetles are extinct: e.g. Cercyon spp. (Hydrophilidae), Hypocaccus spp. (Histeridae), Aphela gotoi (Curculionidae). (2) Partly damaged areas: 80 % of populations of the littoral beetles are recovered. (3) A little damaged areas: no change for the population of the beetles.
