Biogeographic dependent diversification analyses
Diversification models accounting for the influence of biogeographical events on the diversification rates of Preponini suggest that speciation and both the Andean uplift and the closure of the Panama isthmus were exponentially and positively correlated through time (Table 1). In fact, the model with exponentially varying speciation rate depending on Andean uplift had a slightly lower AIC than the time dependent models (Table 1).
