ND: not detected; mean occurrence with same superscript along the same row is not significantly different (P ≥ 0.05). ∗Frequency of occurrence = (total number of each organism in the sample )/(total number of all organisms in the sample). ∗∗Overall occurrence = (no. of locations that each organism is found /(total no. of locations sampled).
