Bayesian skyline plots (BSP) showing estimates of effective population sizes (N<i>_ef</i>) into the past for each of 6 loci.

<p>Each locus is represented by a separate line on each graph. Time (in years before the present) is on the x-axes and N<i>_ef</i> is on the y-axes. Black lines indicate the approximate time of the LGM at 20,000 years before present.
