Summary of empirical analyses. Legend: We compare the results of Likelihood and Bayesian analyses of the Pons et al. Rivacindela dataset. The phylogenetic tree is the maximum clade credibility tree from BEAST and the clades highlighted in red represent the Maximum Likelihood species limits. The colored table is a sequence-by-sequence matrix. Cells are colored by the posterior probability that the corresponding sequences are conspecific, and this allows for the visualization of uncertainty in species limits. Off-diagonal color patterns indicate that some uncertainty in species limits owes to uncertainty in the topology of the phylogeny.
