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).
