Patterns of sequence variability among individual mitochondrial and nuclear markers, combined mitochondrial genes, combined nuclear loci, and combined mitochondrial and nuclear loci. These data comprise the number and percentage of variable sites, the number and percentage of parsimony informative characters (PIC), the consistency (CI) and retention (RI) indices, and the suggested model of nucleotide substitution, as selected under the Bayesian information criterion (BIC). GTR, HKY, G and I represent the General Time Reversible model, the Hasegawa-Kishino-Yano model, the alpha shape parameter describing gamma distributed rate variation, and a proportion of invariant sites, respectively.
