2.b. Variation among populations
In concurrence with previous population genetic studies of I. scapularis (Gulia-Nuss et al., 2016; Ludwig, 2015; Norris et al., 1996; Van Zee et al., 2015), we found an overall moderate amount of genetic differentiation throughout the species range while expanding the geographic and genomic regions surveyed. We were also able to observe varying amounts of differentiation when examining different population comparisons.
