Taxonomic investigation on the protozoan fauna of Japan, with special reference to the diversity crisis due to global climate change.

到目前为止，日本的原生动物区系还没有完整的记录。为此，我们20多位原生动物专家，通过收集原始文献记录，列出种名和采集点，提取可靠的文献目录，为了建立日本原生动物区系的全面编目数据库，我们还进行了全国范围的野外调查，在日本100多个地方，包括北海道的网走地区和冲绳县的南大东岛，生活和寄生原生动物。调查结果已在http://sites.google.com/site/protistsurvey/网站上公布。

Up to the present time, protozoan fauna in Japan has not been fully documented. Therefore, we, more than 20 protozoan specialists, have conducted a systematic survey on the Japanese protozoans by1) collecting original bibliographic records2) listing up species names and collection points, and3) extracting reliable list of literature, in order to construct a comprehensive inventory database of Protozoan fauna of Japan.We have also conducted a nation -wide field survey of free-living and parasitic protozoans at more than 100 locations in Japan, including Abashiri area in Hokkaido and Minami Daito Island in Okinawa prefecture. The result of the survey has been presented on line at http://sites.google.com/site/protistsurvey/.
