Analyses of molecular variance (AMOVA) estimating the amount of genetic variance explained by RO (Guadeloupe, Martinique and Puerto Rico) and RI (French Guiana, Senegal and Réunion; top three rows, in bold) or by all sampling regions (considering all sampled regions individually; bottom three rows, in italic)

Source of variation	Variance components	Percentage of variance
Among RO and RI	0.09 n.s.	6.56 %
Among sites a within RO, RI	0.38 ***	28.30 %
Within sites	0.88 ***	65.15 %
Among sampling regions	0.30 ***	22.35%
Among sites a within regions	0.16***	12.20%
Within sites	0.88***	65.46%
