Results of maximum likelihood tests of diversification models.


Best constant model

Best variable model



pure birth (AIC = 5.82)

DDL (AIC = 4.47)

1.36 (p = 0.21)

Aegla A

pure birth (AIC = 12.56)

DDL (AIC = 4.77)

7.79 (p = 0.02)

Aegla B

pure birth (AIC = 11.79)

rvbd (AIC = 6.32)

5.47 (p = 0.03)

Shown are best constant and best variable rate models selected from six candidate models. Tests of significance were conducted by simulating 5000 phylogenies under a constant birth-death model. The best constant model was rejected if the ΔAICrc was significant (two-tailed alpha = 0.05,[49]). DDL is a logistic density dependent model and rvbd is a rate-variable birth-death model. The best-fitting model is in bold.
