Table 10. Genera represented by single species, with the position of each OTU cluster on each principal component axis and a list of the important characters for each axis (Table 4) and the magnitude (large or small observed values) for the measurements for the most diagnostic characters. See Table 9 for additional explanation of the labeling and interpretation.
