| Research Abstract |
Various benthic dinoflagellates were collected for species identification and establishment of clonal cultures from macroalgae growing in Pacific coastal areas of several prefectures such as Okinawa, Wakayama, Shizuoka, Tokyo. Chiba, and Iwate. Gambierdiscus and Ostreopsis were found from wide areas, although their population densities were low. Physiological characters analyzed using the cultures showed that clones from Honshu had similar optimum salinity range, but better tolerance to low temperature(<20 degree), comparing with those from tropical areas. This fact is important for consideration of distribution expansion mechanisms.
