Fig. 5.

Box plots showing the richness (S), Shannon diversity index (H) and Pielou’s equitability index (J) in Bouzas (A, C, E, G, I, K) and Cesantes (B, D, F, H, J, L) during the four sampling periods. Lines within the plots represent the mean value. The bottom and top boundaries of each boxplot indicate the 25th and 75th percentiles, respectively. The whiskers are the 5th and 95th percentiles, respectively. Letters in the boxes indicate significantly equal mean values within each sampling site according to the post hoc tests (p-value > 0.05). n.s: not significant differences among sampling periods
