Skyline plots. Bayesian skyline plots showing the demographic history for each of the three clades of redside shiner. Black lines represent mean population sizes plotted over time, and blue lines represent 95% confidence intervals surrounding those means. All three clades show a signature of population expansion, albeit beginning at different times in the Pleistocene. The Northern Inland Clade shows the most recent (and most pronounced) expansion beginning ~50,000 years ago.
