Analysis of molecular variance (AMOVA) based on pairwise differences of the plastid trnH–psbA marker for Ficus insipida subsp. insipida. The analysis was run independently using populations grouped by geographical regions (Mesoamerica and Amazonia) and by SAMOVA groups.

Group level	Source of variation	d.f.	Sum of squares	Variance components	Percentage of variation	Fixation indices (P < 0.001)
Geographical regions	Among groups	1	203	0.98	56.21	ΦCT = 0.56
	Among pops within groups	52	218	0.53	30.18	ΦSC = 0.69
	Within populations	356	84	0.24	13.61	ΦST = 0.86
SAMOVA groups	Among groups	6	353	1.21	75.14	ΦCT = 0.75
	Among pops within groups	47	68	0.16	10.13	ΦSC = 0.41
	Within populations	356	84	0.24	14.73	ΦST = 0.85
