Extended Data Fig. 4: Genome scan for differentiated regions between Europe and each invasive range.

a. Empirical p-values for enrichment of C2 (contrast) in 20 kbp windows using the WZA between Europe and each invasive range. Red points indicate the top 1% of WZA scores. Blue bars indicate haploblock locations. b. Overlap between contrast outlier 20 kbp windows and outlier 20 kbp windows within each introduced range (XtX) or across climatic gradients within each range (XtX-EAA).
