Note: For unsimulated samples, sample size is 36, and two groups were analyzed using 999 permutations. For simulated samples, sample size is 360, and two groups were analyzed using 999 permutations. The test statistic (R), p value, and percent variation explained in the first the PCoA axes are presented for each comparison
