  1. H o observed heterozygosity; H e expected heterozygosity; A pr private allelic richness.
  2. For each estimator, the relative reduction of diversity was determined by calculating 1-(DIV1/DIV2), where DIV1 is the estimator of diversity in the supposed original gene pool and DIV2 is the estimator of diversity in the supposed original gene pool.
  3. Bold values represent significant reduction of diversity at *P < 0.05, **P < 0.01, and ***P < 0.001.
  4. 1 computed based on all SSR loci used in this study (25 loci); 2 computed based only on 24 SSR loci under the assumption of neutrality.
