Abstract
an epilithic periphyton community howed
significant seasonal changes I species composition , abundance and photosynthetic rates in a slow-flowing , mammade stream. Blue green algae were dominant during summer, diatoms were dominant during spring and winter, and green algae dominated the community during fal. The highest photosynthetic rates were found in winter with 240C as the optimum temperatures for
production in all seasons.
