项目摘要

Morphology of species belonging to the genus Alexandrium were observed in details, including several toxic ones that cause paralytic shellfish poisoning (PSP). Plankton samples collected from many areas in the world were used for the study as well as cultures maintained in several culture collections. Efforts were made to collect samples at the type locality of each species, in order to increase taxonomic accuracy.These results obtained were ;1. Totally 22 species, which were previously described in taxonomic articles, were observed. They are : A.acatenella, A.affine, A.andersonii, A.catenella, A.compressum, A.concavum, A.fraterculus, A.fundyense, A.hiranoi, A.insuetum, A.leei, A.lusitanicum, A.margalefii, A.minutum, A.monilatum, A.ostenfeldii, A.peruvianum, A.pseudogonyaulax, A.satoanum, A.tamarense, A.tamiyavanichii, A.taylorii, and A.tropicale. These species were carefully observed and described again in the report with photographs. Several species were compared with specimens collected at the type locality for taxonomic discussion.2. Several taxonomically undescribed morphotypes were also collected and observed.3., Sixteen described species among the 22 species, and two undescribed morphotypes were occurred in Japanese coastal waters, .4. Three species, A.andersonii, A.minutum and A.ostenfeldii, which are known to cause PSP in some countries outside Japan, were found in Japanese waters for the first time in this study. Monitoring on the occurrence of the three species is inevitable as well as three species that already recognized as PSP causative species in Japan A.catenella, A.tamarense and A.tamiyavanichii.5. Though the toxicity of culture strains established in the present study were analyzed, any new toxic species has not been found.

在细节上观察到了属于亚历山大属的物种的形态，其中包括几种引起麻痹贝类中毒（PSP）的有毒毒性。从世界许多领域收集的浮游生物样本都用于研究，以及在几种文化收藏中维持的文化。为了提高分类学的准确性，已努力在每个物种的类型中收集样品。这些结果是； 1。总共观察到了22种，这些物种以前在分类学文章中进行了描述。 They are : A.acatenella, A.affine, A.andersonii, A.catenella, A.compressum, A.concavum, A.fraterculus, A.fundyense, A.hiranoi, A.insuetum, A.leei, A.lusitanicum, A.margalefii, A.minutum, A.monilatum, A.ostenfeldii, A.peruvianum, a.pseudogonyaulax，a.satoanum，a.tamarense，a.tamiyavanichii，a.taylorii和a.tropicale。在报告中仔细观察并再次描述了这些物种的照片。将几种物种与在类型地区收集的分类学讨论中收集的标本进行了比较。2。还收集并观察到了几种分类学未描述的形态。3。，在22种中描述了16种的物种，在日本沿海水域中发生了两种未描述的形态，.4。在这项研究中，在日本水域中发现了三种物种，即众所周知，在日本水域中引起了众所周知的PSP。对这三种物种的发生进行监测是不可避免的，三种物种在日本a.tamarense和a.tamiyavanichii.5。尽管分析了本研究中建立的培养菌株的毒性，但尚未发现任何新的毒性物种。
