  • a All averages of diversity measures were calculated using 10 iterations of data rarefied to the lowest number of isolates obtained on a single growth medium. Significant differences (P < 0.05) indicated by letters across rows were calculated using Student's t tests of all the iterated data for replicates for each sample source-medium combination.
