Population genetics parameters and tests.

-Abbreviations: n-sample size, %C-frequency of common invasive haplotype.-Descriptive statistics: π-nucleotide diversity, HD-haplotype diversity, τ-the date of population growth in mutational time under the expansion model, rg-raggedness, F*-Fu&Li’s F*, D*-Fu&Li’s D*, D-Tajima’s D, Fs-Fu’s Fs.-Statistical tests: ND-probability of non-differentiation (used to justify combining India, Israel, and select invasive populations as panmictic), ED-test of demographic expansion p-value, ES-test of spatial expansion p-value.-Descriptive statistics could not be calculated for populations with HD = 0.-Expansion tests were conducted for panmictic populations and populations where n>7.-Significance is assessed under a two-tailed test for all test statistics and ND and a one-tailed test for ED and ES.-Bold denotes significance favoring expansion while italics denote significance rejecting an expansion model.1Farris et al. [12];2The invasive panmictic population includes all populations with a sample size >7 and a common invasive haplotype frequency >90%.Population genetics parameters and tests.
