Fig 2. F_ST estimates based on 2001–2014 barcode data plotted with respect to inter-clinic distance.

Annotations refer to site comparisons using abbreviated clinic names (MLA for Maela, 212 parasite samples; WPA for Wang Pha, 457 parasite samples; MKK for Mae Kon Ken, 116 parasite samples; and MKT for Mawker Thai, 388 parasite samples). All parasite samples were single-infection. For a clinic pair, A and B say, the F_ST estimate was based on n_A + n_B parasite samples, where n denotes the number of parasite samples per clinic. Error bars represent 95% confidence intervals based on bootstrapping over SNPs.
