Development of database on harmful plankton image and related publication on their ecophysiological characters

在项目期间，Fukuyo和Furuya观察了浮游生物样品，Matsuoka观察了孢囊样品，通过对各种形态特征进行详细的形态描述和拍照，确定了样品中的甲藻。照片总数超过1500张，而几个重要的物种经常被拍摄。其中，显示形态特征的照片有利于物种识别，被扫描仪输入计算机数据库。将收集的数据重新整理后，在万维网系统（www.example.com）上以"沟鞭藻图集"的名义从主要研究者的主页上向公众开放。其中包括原甲藻目15种、甲藻目28种、膝沟藻目77种共200余种，并附有相关文献，以说明其毒性和危害性。其中，对有毒有害物种的数据准备较多，如20种亚历山大藻，其中大部分产生PSP毒素，以及30种无甲藻，包括造成有害后果的赤潮的裸甲藻。一张照片通常不足以显示每个物种的形态特征，有时需要从不同角度拍摄十多张照片。Ogata收集了有关其毒性和危害性的科学证据的参考出版物，并将其保存在光盘中。该光盘已邮寄给世界上研究有害藻类的科学家，并分发给在塔斯马尼亚举行的第九届有害藻类水华国际会议的与会者。2000年2月，澳大利亚。由于难以接近计算机系统的科学家希望打印地图集的小册子，因此从计算机数据库中选择了一半的照片并打印了该项目的最终报告。

During the Project, Fukuyo and Furuya observed plankton samples and Matsuoka observed cyst samples, identifying dinoflagellates in the samples by making detailed morphological description and taking photographs on various morphological characteristics. Total number of photographs became more than 1500, while several important species are taken often. Among them, photographs that show morphological features good for species identification were taken into the computer data-base by a scanner. The accumulated data were reorganized and opened to the public from home-page of the main researcher in the world wide web system (dinos.anesc.u-tokyo.ac.jp) under the name of "Atlas of Dinoflagellates". The data were also reorganized and saved in CD-ROM, in which about 200 species including 15 Prorocentrales, 28 Dinophysiales and 77 Gonyaulacales with a list of reference publications to show scientific evidences on their toxicity and harmfulness were saved. Among them, more data were prepared for toxic and harmful species such as 20 species of Alexandrium, most of which produce PSP toxins, and 30 species of unarmored dinoflagellates including Gymnodinium which cases red tides with harmful consequences. One photograph was usually not enough to show morphological characteristics of each species and sometimes more than ten photographs taken from various angles were used. Reference publications showing scientific evidence on their toxicity and harmfulness were collected by Ogata and also saved in the CD-ROM. The CD'ROMS were mailed to scientists studying harmful algae in the world, and distributed to participants of the 9th International Conference on harmful Algal Blooms held in Tasmania. Australia in February 2000. As scientists who have difficulty in approaching to computer system wanted to have printed booklets of the Atlas, a half of photographs from the computer data-base were chosen and printed with the final report of the project.
