Table 1 Sequence variation for each gene region and for the three concatenated matrices (mitochondrial: cox1 + 16S; nuclear: PEPCK + EF-1α + wg; combined: all five gene fragments combined)

From: Molecular phylogeny and timing of diversification in Alpine Rhithrogena (Ephemeroptera: Heptageniidae)

  1. n = number of sequences, bp = size of aligned matrices, K = number of haplotypes (cox1, 16S) or genotypes (PEPCK, EF-1α, wg) or a combination of both (combined), S = number of polymorphic sites, S i = number of parsimony-informative sites, Model = best evolutionary model selected following the second-order Akaike information criterion (AICc). Concatenated matrices were examined with partitioned analysis using the best model for each gene fragment (see Methods)
