Distribution of Change in Gene Diversity for M. montanus between 2,525 and 166 ybp, Based on Serial Coalescent Simulations

<p>Sampling is modeled at two points in time. <i>N_{e-mm_ecol}</i> estimates from <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0020290#pbio-0020290-g002" target="_blank">Figure 2</a> are used to specify demographic history. Eight of the nine combinations of mutation rate and density allow us to reject the null hypothesis for a closed population (<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0020290#pbio-0020290-t002" target="_blank">Table 2</a>). This figure illustrates simulation results for moderate density and moderate mutation rate (4% per million years per bp). The probability of the observed change (shown by dashed arrow) is significant (<i>p</i> = 0.015).
