Spatial patterns in DGR diversification. The proportion of aggregates showing diversification is shown for each DGR locus at each sampling site. A DGR locus was considered to be diversified if at least one of its VRs showed diversification at positions targeted by the DGR mechanism based on the nucleotide diversity. Similar results were obtained when using the proportion of non-reference alleles. Colors correspond to sampling sites, with blue shades corresponding to Little Sippewissett (LS), green to Great Sippewissett (GS), and red shades to Penzance Point (PP). SI Appendix, Figs. S8 and S9 show these results at the target and VR level as well as the number of diversified aggregates in each case.
