Figure 3. Rarefaction analysis showing the changes in haplotype richness relative to successive increments in sample sizes.

Figure 3

Rarefaction curves of two groups of populations sampled for at least ten individuals. The test was significant for the differences in haplotype richness between these groups (t = 12.5, df = 19, P<0.0001). The mean number of haplotypes found in 10 samples randomly drawn from the group PERD/PESB/SMJ was 7.0 (SD = 1.3), whereas the mean was roughly half as much (X = 3.5, SD = 0.2) for the groups found in smaller areas (RPPN-FMA/RPPN-MS).
