Demographic history of M. leidyi for invasive and native populations. PSMC model with estimates of the demographic changes (Ne = effective population size) over time (generations, log scale) for all populations including the native southern (Miami, red, n = 15) and northern (Woods Hole, blue, n = 16) populations as well as the invasive southern (Black Sea, Varna, green, n = 16; Western Mediterranean, Villefranche, orange, n = 9) and northern (North Sea, Sylt, purple, n = 16) populations.
