Table 3 Single-level AMOVA results for each Sabatieria species based on ITS sequence data

Source of variation	df	var (%)	Φ _st	P
*Species I*
Among populations	4	88.59	0.886	***
Within populations	195	11.41
*Species II*
Among populations	2	76.48	0.765	***
Within populations	63	23.52
*Species III*

Values are based on a K2P model, as indicated by jModelTest. df = degrees of freedom, var. = percentage of variation, Φ _st = fixation index, P = permutational P-value, based on 1000 permutations. Significant Φ _st values are indicated in bold. Significance codes: *** P < 0.001
