Table 1 Comparative analyses conducted with the Concentrated-Changes Test [9] in Araceae.

From: A comparative analysis of pollinator type and pollen ornamentation in the Araceae and the Arecaceae, two unrelated families of the monocots

  1. P-values obtained through a Fisher's exact test performed on the distribution of events with the coding 1 ('Psilate/Verrucate' (P/V) vs. 'Other Ornamentation' and 'Beetle' (B) vs 'Other Pollination') and the coding 2 ('Echinulate' (E) vs. 'Other Ornamentation' and 'Fly' (F) vs 'Other Pollination'). The results are given when the character 'pollination type' depends on the 'ornamentation type' (P/V → B, E → F) and conversely (B → P/V, F → E) and only with ACCTRAN optimization (complete and detailed results in additional files 6 and 7). Polymorphic species were removed.
