Extended Data Fig. 2: Population structure within and among native and introduced ranges.
a. Weighted pairwise fst within each range, weighted pairwise fst values between native and introduced populations, and weighted pairwise fst values between populations in different introduced ranges. Pairwise fst values are generally low and similar across all worldwide populations. Number of pairwise comparisons included in each boxplot is presented on x-axis below each box. Box edges in boxplots represent the interquartile range, center line represents the median, and upper and lower whiskers are the largest value either greater or less than, respectively, 1.5 times the interquartile range. b–g. Mantel tests for isolation by distance (b-d) and isolation by environment (e-g) across the native range (b,e), North America (c,f) and South America (d,g). Mantel tests are two-sided.
