^† Values with different letters within rows are significantly different using Kruskal-Wallis and Mann-Whitney Tests: abundance between sites, K=15.92, DF=2, p=0.0003; richness between sites, K=8.17, DF=2, p=0.0157; abundance between seasons, K=42.42, DF=3, p=0.000; richness between seasons, K=50.15, DF=3, p=0.000.

^‡ Diversity values with different letters within rows are significantly different at p<0.05, using permutation and bootstrap tests in PAST program.
