2007年10月和2008年1月至2009年12月，分别在日本东海湾工业港的一个站点通过形态学扫描电镜观察和以大亚基（LSU） rDNA为主的分子分析，鉴定了7种骨骼类。我们指的是一种使用LSU rDNA鉴定的as . dohrninia，但使用小亚单位（SSU） rDNA鉴定的as . marinonia，因此我们使用术语。marinoi-dohrniicomplex。这是第一次。浪漫的年代。costatums.s。, and。在日本有记录的假海龟。menzeliiandS。热带植物已在日本通过分子方法鉴定。帖前。marinoi- dohrniiccomplex一年四季高频分离。日本病菌在美国夏季也有较高的分离频率。热带从9月到12月被隔离，但是。ardensandS。costatums.s。只有在水温超过20℃时才会被分离假花只在夏天开过一次，但是。menzelii于5月和10月被分离出来。s。costatums.l。海湾里的生物是由这七个物种的演替支撑的。六种，除了。门氏藻是海湾中藻华的重要组成部分。每个月都能分离出一到四种骨瘦体。月物种多样性较高时。花园；, and。通常与热带或亚热带水域有关的热带植物被分离出来。总体而言，东海湾内的骷髅属物种多样性非常高。
SevenSkeletonemaspecies were identified at one station in the industrial harbor Dokai Bay, Japan, in October 2007 and then monthly from January 2008 to December 2009 by morphological scanning electron microscopy observations and molecular analyses of mainly the large subunit (LSU) rDNA. We refer to one species identified asS. dohrniiusing LSU rDNA, but asS. marinoiusing the small subunit (SSU) rDNA and consequently we use the termS. marinoi-dohrniicomplex. This is the first time thatS. ardens,S. costatums.s., andS. pseudocostatumhave been recorded in Japan and thatS. menzeliiandS. tropicumhave been identified by molecular methods in Japan. TheS. marinoi-dohrniicomplex was isolated with high frequency all year-round, andS. japonicumwas also isolated with high frequency but not so in summer.S. Tropicumwas isolated from September to December, butS. ardensandS. costatums.s. were isolated only when the water temperature exceeded 20°C.S. pseudocostatumbloomed just once, in summer, butS. menzeliiwas isolated in May and again in October. The continuous year-round occurrence ofS. costatums.l. in the bay is supported by the succession of these seven species. Six of the species, exceptS. menzelii, were important components of algal blooms in the bay. One to four species ofSkeletonemawere isolated every month. Monthly species diversity was higher whenS. ardens, S. costatums.s., andS. tropicumthat are usually associated with tropical or subtropical waters, were isolated. In general, species diversity of the genusSkeletonemawas very high in Dokai Bay.
