Table 3. Comparison of the fit of the models tested in BioGeoBEARS, all including or not founder-event speciation (“+j”).
Log-likelihood ln(L), Akaike information criterion corrected for sample size (AICc), difference in AICc value compared with the best model (ΔAICc), and the Akaike weights (ωi) showing the relative likelihood of each model.
