  1. Taxa used in comparisons include two sister taxa (=P1, P2), one taxon outside of P1, P2 (=P3), and one outgroup (=O). Positive D-statistics (=D) represent an excess of loci supporting ABBA verses BABA topologies, thus indicating potential introgression between taxa P2 and P3. Range of Z-scores for each set of tests (=RangeZ) and the number of significant tests out of the total number of tests (=nSig/ntest) are also reported, as is the overall Z-score (=Z), average number of alternatively discordant loci (=BABA and ABBA), and the average number of loci per test (=nloci). Significant Z-scores are in bold, as are the species involved with introgression. All tests are represented by species names with the exception of Pantosteus where multiple species occur in the former genus. Some species are divided into region, with abbreviations as follows: UCR Upper Colorado River, TAM Tampico Springs, AGR Agra Remora, RNU Rio Nutria, ULC Upper Little Colorado, WAS Willow and Silver creeks, WEN Wenima Wildlife Area, VR Virgin River BW Bill Williams River, GI Gila River Basin
