Image database system of type specimens of, Cenozoic smaller foraminiferal species, and taxonomic study of foraminifera from Japan.

为提高有孔虫分类学的稳定性，建立了日本新生代小有孔虫模式标本图像数据库系统，主要内容如下：1.在日本岛屿及周边海域模式标本有孔虫物种数据库的基础上，对数据库进行了修改，增加了若干补充数据，并上传至互联网系统。2.对日本及周边海域的有孔虫物种，考察了日本几个研究所和博物馆的正型和模式系列的保存状况。这一结果发表在日本古生物学会年会上。3.为了了解该物种的形态变异和古生态背景，我们对每个类型的地点进行了调查，并收集了地形标本。4.利用低真空扫描电子显微镜、数字高清显微镜等手段制作了数百种主要类型的图像数据，建立了有孔虫图像数据库。5.通过7期《有孔虫》通讯、熊本、秋田、鹿贺、仙台4次研究会、动物分类电子邮件等，计划开展有孔虫等微体化石分类、(古)生态学、地层学、(古)生物地理学、古海洋学等方面的信息交流。

For stability of foraminiferal taxonomy, an image database system has been prepared on the type specimens of Cenozoic smaller foraminifera from Japan, as follows :1.On the database of foraminiferal species with the type specimen from the Japanese Islands and the surrounding seas, we revised the data set and added several additional data, and has loaded it up the internet systems.2.On foraminiferal species from the Japan and the surrounding seas, we inspected the state of storage of holotype and the type series at several institutes and museums in Japan. This result was reported at an annual meeting of the Palaeontological Society of Japan.3.To understand the morphologic variation and paleoecologic background of the species, we have surveyed each type locality, and have collected topotypic specimens.4.An image database of foraminifera was constructed on the base of image-data of primary types of a few hundreds species, which were made by using a low-vacuum scanning electron microscope (L-SEM), digital HD micro-scope and so on. This database is introduced to the public tentatively on the Internet before the future general release.5.The exchange of various information such as taxonomy on foraminifera and other microfossils, advanced researches of foraminifera on (paleo-)ecology, stratigraphy, (paleo-)biogeography, paleoceanography, etc. was planned through seven issues of news letter "Forams-Net", research meetings of four times held at Kumamoto, Akita, Kaga, and Sendai, the debate about zoological classification by E-mail, and so on.
