Phylogeographical structure and demographic reconstruction through time inferred from 841 base pairs of the nuclear internal transcribed spacer region (ITS) for the North American vaejovid scorpions Pseudouroctonus reddelli and Pseudouroctonus sprousei . (a) Time-calibrated Bayesian gene tree for P. reddelli and P. sprousei. Nodes that received ≥ 0.95 posterior probability support depicted with white dots. (b) Bayesian skyride plot for P. reddelli, showing change in effective population size since the time of the most recent common ancestor. HPD = highest posterior density; LGM = Last Glacial Maximum.
