Fig 1.
Sampling stations in Todos os Santos Bay.
Reefs under normal conditions are represented by white circles while reefs under phase shift (high zoantharian cover) are signed by black circles.
Fig 2.
Probabilities of numbers of fishes species by number of samples with (a) number of species observed (Sobs) in normal (NR) and phase shift (PS) reefs with their respective confidence intervals (95%), and (b) estimators of species richness of reefs in phase shift (PS) in comparison with the number of species observed in normal reef (NR) and its confidence interval less than 95%.
Fig 3.
Multidimensional scaling of trophic structure of reef fishes assemblage on normal reefs (represented by dark balls) and phase shift reefs (dominated by the zoantharian Palythoa cf. variabilis), which in figure are represented by asterisks.
Table 1.
Dissimilarity between the trophic structure of reef fish on normal and phase shift (high zoantharian cover) reefs calculated by Similarity Analysis.
Fig 4.
Density of fish per reef, where a point represents each station-value. The mean value for each group of reef is represented by the dash line and asterisk (*) marks the graph that had a significant difference (p < 0.05) according the Student's t test.
