Table 3 Output of the PERMANOVA analysis carried out to test for differences in total meiofaunal abundance, richness of higher taxa, taxonomic composition between undisturbed and disturbed mangrove areas (df = degrees of freedom; MS = mean square; Pseudo-F = F statistic; P(MC) = probability levels obtained from Monte Carlo asymptotic distributions).
