| Seasonal changes of the phytoplankton and the periphyton community were investigated from August 1998 to April 1999 at five stations at the Suer stream in Kwangyang. A total of 112 species of phytoplankton were identified. Of those, the diatoms were present at all stations but the green algae, the bluegreen algae, and the dioflagellates were present at Station 4 and Station 5 more frequently than the other stations. The phytoplankton standing crops varied from 10,100 cells/1 at Station 4 in April 1999 to 1,489,100 cells/1 at Station 4 in October 1998. The seasonal variation patterns of phytoplankton standing crops were different among stations as well as the pattern of presence. The dominant species were as follows: Achnanthes minutissima, Aulacoseira distans v. alpigena, Cocconeis placentula v. lineata, Cymbella minuta, C. silesiaca, Fragilaria arcus v. recta, Peridinium cinctum, Rhizosofenia longiseta, Synedra rumpens and filamentous algae. Of those, Achnanthes minutissima, Rhizosolenia longiseta, Synedra rumpens and filamentous algae showed the highest rate of occupation in the phytoplankton standing crops during the investigated periods. A total of 99 species of periphyton were identified. Among those, the diatoms of the periphyton community were observed frequently rather than those of the phytoplankton community. The ecological indicator values showed ${ate}$-mesosaprobous in saprobity and was close to eutraphentic in trophic state. There were no considerable differences between the ecological indicator values by planktonic diatoms and periphytic diatoms. |
