Table 5. Biomass (g FW m -2) (A.) and density (ind m -2) (B.) of the main taxa contributing to similarities within and dissimilarities among seasons and among submersion periods within the seasons (from SIMPER analysis).
Mean ± standard deviation values are presented. Grey colour identifies increasing values with increasing submersion period in each season.
