Demographic histories
PSMC identified three major demographic histories: distinct insular and continental histories within M. caurina and a single general M. americana history with greater variance relative to either M. caurina distribution (Fig. 3b). All M. caurinadistributions are lower (Ne) than M. americana , with insular M. caurina exhibiting the lowest Neof all groups examined. Of the populations examined, CHI has the highest historic peak in Ne, while MAK had a larger effective population size recently.
