Wilcoxon test results for the support of genetic bottlenecks in the past of the Psidium guajava populations of Isabela (ISA), Santa Cruz (SCZ) and San Cristobal (SCY) islands (software BOTTLENECK).

Both, the SMM and TPM mutation models implemented in BOTTLENECK were used. One-tailed tests were performed in order to determinate whether the genetic bottleneck occurred because of a heterozygosity (H) deficiency (which may happen after a dramatic expansion on the population size) or a H excess (which may happen after a dramatic reduction on the population size).
