Maps showing pie charts of cytochrome-c-oxidase 1 (COI) haplotype frequencies in the invasive parasite species Mytilicola intestinalis and Mytilicola orientalis. Shown plotted overlaying the maps are pie charts for the different sampling locations, while the large pie charts in the corner of the maps represent the grouped frequencies for all locations in that map. On the side, the large pie charts represent the grouped frequencies for all invaded European locations for M. intestinalis and M. orientalis (“Europe”), and for all invaded locations for M. orientalis that includes the North American samples (“Invaded”). Note that the pie charts from the Mediterranean and Japan represent the overall frequencies of all sampled native sampling locations for M. intestinalis and M. orientalis, respectively. Pie charts are smaller for sampling locations with fewer than 15 individuals, which were not included in our analyses. Colors correspond to large scale differentiation between clusters of haplotypes in the minimum spanning networks presented in Fig. 2. Pie charts were made in R statistical environment version 3.4.383, maps were plotted with R packages rworldmap67 and ggplot68 and Fig. 4 was assembled in Adobe Illustrator.
