Table 1.

Location, sample size and genetic diversity parameters for each of the 14 populations of Livistona mariae and L. rigida. We divided the 14 populations into three regional groups based on their locations. n, sample size; H_E, expected heterozygosity; allele richness [16], allelic richness; private allele, mean number of private alleles (i.e. those that are unique to a given population, p and region, r) per individual. Allelic richness values denoted by the same letters are not significantly different from each other at the p < 0.01 level (Scheffé's multiple comparison test.)
