Demographic patterns of each clade and the total population as determined from the Bayesian skyline plot (BSP).

Abstract

<p>The X-axis is in units of million years in the past and the Y-axis is <i>N</i>_e*µ (effective population size × mutation rate per site per generation). The median estimates for the log10 of the population size are shown as thick solid lines, and the 95% highest posterior density (HPD) limits are shown by the shaded areas.</p
