Table 1.
Results of PERMANOVA main test for the α-diversity indexes calculated: Shannon Diversity, ChaoI and Observed OTUs.
| Source of variation | Pseudo-F (Shannon/ChaoI/Obs. OTUs) | P (perm) (Shannon/ChaoI/Obs. OTUs) | PERMDISP (P) (Shannon) |
|---|---|---|---|
| Nutrients | 4.3878/5.8915E-2/0.46874 | 0.044/0.816/0.503 | 0.06 |
| Seaweeds | 2.4843/0.98266/1.4276 | 0.094/0.398/0.257 | 7 |
| Nu × Se | 1.938/0.35053/0.65214 | 0.157/0.716/0.512 | 8 |
PERMANOVA values were calculated after Euclidian distances calculation for Shannon values. H0: there are no differences in the α-diversity for the different treatments, H0 rejected if: p < 0.05. Factors abbreviations: Nu, Nutrients; Se, Seaweeds, Bold face values are significant at P < 0.05, P-values based on 999 permutations.
