Descriptions on the Plate Patterns of Genus Protoperidinium for Plankton Monitoring Network

플랑크톤 모니터링 네트워크를 위한 Protoperidinium속의 패각 유형 기재

In thecate dinoflagellates, the thecal plate pattern has been considered to be important criteria in their classifications. Due to this fact the shape of the theca and the arrangement of the theca were studied. In the pictures, the distinctions between the plates in the cells were so vague that I drew a diagram to illustrate the plate pattern. To identify the genus Protoperidinium, the shape of the first apical plate and the second anterior intercalary plate were used. Depending the shape of first apical plate, will be designated as meta(4), meta(5), para(4), para(5) or para(6). The shape of first apical plate is considered an important factor. From this point of view, the genus Protoperidinium as a group of planktonic protist in the coastal environment was classified.
