Rarefaction curves with 95% confidence intervals of haplotype diversity for populations of I. scapularis in the western and eastern geographical regions. The numbers next to the curves indicate the total estimated number of haplotypes using the non-parametric Chao 2 estimator. See list of abbreviations for the complete names of localities of the tick populations.
