A principal coordinates analysis (PCoA) (Fig. 3) was performed using unweighted UniFrac distances allowed to further analyze the factors responsible for significant differences between groups of samples in the second sequencing event. Fig 6 shows a clear grouping along both the x-axis (PC1 = 29.36% of variability) and the y-axis (PC2 = 12.24%) between the control, acetone and atrazine3 samples. The remaining treatment groups clustered farther away with increasing dosages of atrazine, indicating more similar microbial compositions were the result of the atrazine treatments.
