Table 1 Indicator species analysis Monte Carlo method (4999 permutations) results, where the observed indicator value (IV) is the percent of perfect indication based on relative abundance and relative frequency, the randomized IV is calculated from randomized groups, and P is the proportion of randomized trials with indicator value equal to or exceeding the observed indicator value. Only species significant at the α < 0.05 level are shown
