Extended Data Fig. 7: Additional ABBA-BABA tests focused on V. sulcatum.
From: Replicated radiation of a plant clade along a cloud forest archipelago
Tests 1-8 show little discordance, suggesting that V. sulcatum has not been an introgressive donor into Eastern Mexican species of Viburnum. By contrast, tests 9-18 show much greater discordance when Eastern Mexican species are tested as introgressive donors into V. sulcatum compared to a taxon from Chiapas (V. jucundum) or Oaxaca (V. acutifolium). This suggests that V. sulcatum has introgressed with one or more species from the Eastern Mexican clade, but significance at the Z > 5 level is only seen in some tests and varies depending on the P3 and P1 taxa selected.
