Population genetic statistics for the four major clades, as well as among populations within the two largest clades (V & VII).

R80S = the population genomic dataset used to calculate these statistics (see Table S2).
HO = Observed Heterozygosity; He = Expected Heterozygosity; Gis = Inbreeding Coefficient; SD = Standard Deviation, 95%c.i. = 95 confidence interval.
To test for differences in genetic diversity due to different sample sizes among clades, we calculated genetic diversity statistics on random 14 sample subsets of Clade V and VII (Table S8) but did not find significant differences.
