| Abstract: | The annual growth potential of the benthic microalgal community inhabiting tidal flat sediments in Shinkawa-Kasugagawa estuary in the Seto lnland Sea，Japan was investigated. The growth activity of the community increased with increasing temperature. The growth rates at 6-23℃ (autumn-early summer) were 0.3-3.0 divisions d-1，which were similar to those of pelagic phytoplankton species. Much higher growth rates up to ca.5 divisions d-1 were observed in summer at around 30℃. The growth rate of a unialgal culture strain of Nitzschia sp.，dominated in the hot season was high (close to 4 divisions d-1) at around 30℃. Growth activity was low during low tide when the tidal flat was exposed and high when the flat was submerged. Our results indicate that the benthic microalgal community inhabiting the subtropical tidal flat has an extremely high growth potential in summer，and sustains the majority of higher trophic organisms as a major primary producer of the tidal flat ecosystem. |
