Fit of equilibrium distributions for E. verticillata-1 population and E. verticillata-2 population. a) E. verticillata-1. b) E. verticillata-2. X axis: Pairwise Differences. Y axis: Frequency. The circles show the observed distribution of pairwise difference. The solid lines represent the expected equilibruim distributions. In equilibrium populations, the expected curves are free of waves. The observed curves with many peaks or resemblance to expected curves mean equilibrium population. On the contrary, unimodal curves represent population expansion [39].
