Figures refer to symmetrical measures of molecular diversity (average gene diversity over all loci, see Schneider et al., 2000), and the mean of the asymmetrical Sörensen distance among samples of a given population (only those with n ≥ 5).

Percentages of polymorphic bands were calculated with respect to the number of bands present in a given population.

For G. macrocarpa, Pearson correlations of diversity measures and specimen number are given.
