Table 2.
Averaged percentage of cell abundance and cell biovolume (mean ± standard deviation, SD) for different groups of diatom relative to the total abundance of large-sized phytoplankton fraction (autotrophic fraction >10 µm), under Spring and Neap tidal regimes. The main characteristics of the diatom groups are described in the Experimental Section and photographs are available in the Supplementary Information.
