Table 2 Results from DEC* analysis of geographic range evolution on the Distichodus phylogeny. Results are presented for each of the three analyses based on different BEAST2 input chronograms (derived from analyses 5, 8, and 14). Comparison of alternative models (biogeographic hypotheses) and their support as assessed via Akaike weights. M0 (unconstrained, dispersal to and from the Congo Basin); M1 (allowing only dispersal out of the Congo Basin); M2 (allowing only dispersal into the Congo Basin); dispersal (d); extinction (e); number of parameters (k); Akaike information criterion (AIC); Akaike Weights (AW)

From: Pattern and timing of diversification in the African freshwater fish genus Distichodus (Characiformes: Distichodontidae)
