Entries are the average (standard error) across 100 100-tip birth-death trees.

1

Mean percent of the 100 trees that differ in the identity of the top 5 (or 20) ranked species under contrasting transformations. Standard errors in brackets.

2

The mean across 100 trees of the sum of the differences in the ranks between two transformations. Standard errors in brackets.
