Results of principal components analysis, and morphology versus time relationship.
Panel A: Principal components scatterplot of size-corrected data. Unless otherwise indicated (F), all specimens are male. Panel B: Relationship between “troglomorphy index” and divergence time estimates for troglomorphic populations/taxa.
Figure 4.
Combined-data 50% majority rule consensus Bayesian tree.
Major clades are named, thick branches are supported by a posterior probability of 95 or higher. Troglomorphic populations/taxa indicated by special icons.
Figure 5.
Based on three calibration points (arrows), with 95% confidence intervals for all estimated nodes. Confidence intervals for the root of the tree and the outgroup clade are given below the nodes. Posterior probabilities less than 95 are shown with red node bars. Troglomorphic populations/taxa indicated by special icons.
