Table 4 The tempo of labrid diversification.

From: Does evolutionary innovation in pharyngeal jaws lead to rapid lineage diversification in labrid fishes?

# of shifts clade r ε AIC ΔAIC
0 (whole-tree birth-death model) whole tree 0.053 0.912 307.76

  1. Clade number refers to rate shifts identified in Fig. 2. r is the net diversification rate, ε is the extinction fraction (d/b). AIC and ΔAIC show improvement of AIC score over a constant rates birth-death model as clades are allowed to change rates. Background shows background rates of other labrid clades under the two-rate model.
