Mismatch distributions of Mytilicola intestinalis (top row) and Mytilicola orientalis (lower row). From left to right: mismatch distributions based on population differences (M. intestinalis: all locations pooled; M. orientalis: Iwaya separate from the rest of the locations), mismatch distributions in the putative native region and in the invaded region(s). The sharp decline in M. intestinalis is indicative of population expansion after a bottleneck or selective sweep; the bimodal distributions in M. orientalis are indicative of stable demographics.
