^a

S_obs, observed richness.

^b

Data represent Good's coverage, calculated as the number of OTUs that were sampled once/the total number of individuals in the sample.

^c

Data represent averages of the results of two replicate experiments.

^d

Data were calculated based on 3,854 sequences per replicate obtained by a random resampling approach.
