FIG 6.
Principal coordinate analysis of microbiota from sand samples collected from Florida beaches. The relationship between the ordination plot and the distance matrix had an r2 value of 0.74. The families listed represent the taxonomic assignments of OTUs that significantly affected positioning along either axis (P < 0.05) and were present at a mean relative abundance of >1.0% among all samples. Families are listed in order of declining abundance. No families showed significantly higher relative abundances with a decrease in the y-axis coordinate.
