Table 2. Similarities percentage (SIMPER) analysis for each taxon/group by stations ST1, ST2, and ST3.

Analyses was done on samples for light microscopy (N = 38) and net phytoplankton samples (N = 27), of which N = 15 at ST1, N = 14 at ST2, and N = 36 at ST3. Blank cells are values that could not be determined because there were less than 40 cells in 1L. Taxa with similarity contribution <2 have been excluded from this table. Abbreviations: average contribution/standard deviation (δ/ σ), species contribution (Σδ%).
