Diversification of the Amazon biota: Rivers as vicariant barriers.



-Download georeferenced distributions through the Global Biodiversity Information Facility (GBIF: http://www.gbif.org) for species of the Amazon basin (Aves, Magnoliophyta, Insecta, Squamata, Amphibia, Mammalia).

-Gathering phylogenetic clades for distributed species in the Amazon basin.

-Data cleaning under the protocol proposed by R-Alarcon., & Miranda-Esquivel. (in prep). 

-Delimitation of areas of endemism under the optimality criterion implemented in the program NDM/VNDM. 

-Localization the isolating barriers for different taxa with distribution in the Amazon basin using the Vicariance Inference Program (VIP) (Arias et al. 2011).

-Analysis of events under models (Ronquist, MC, Reconciled) implemented in TreeFitter 1.3B1 (Ronquist, 2002).
