Figure 4. Interpopulation FST values between Escherichia coli from 3 species of primates in 3 forest fragments near Kibale National Park, Uganda, and E. coli from both humans and livestock living in villages associated with the fragments. BWC, black-and-white colobus; RC, red colobus; RT, red-tailed guenon. Error bars represent standard errors of the mean, estimated from bootstrap analyses with 1,000 replicates. Different letters within bars indicate statistically significant differences in FST values (exact probabilities <0.05).
