“…However, detailed studies involving these cladogenic processes in the Andes and the Neotropics are more common in vertebrates than in plants to date (Young et al, 2002;Hall, 2005;Weir, 2006;Brumfield & Edwards, 2007;Ribas et al, 2007;Torres-Carvajal, 2007;Elias et al, 2009;Santos et al, 2009;Chaves et al, 2011), in part because of greater baseline field knowledge and collecting efforts in some animal groups compared with plant groups. Historical biogeographical explanations for Andean radiations are increasingly based on timecalibrated phylogenies and use of explicit biogeographical models (Richardson et al, 2001;Berry et al, 2004;Kay et al, 2005;Moore & Donoghue, 2007;Alzate, Mort & Ramirez, 2008;Drummond, 2008;Antonelli et al, 2009;Cosacov et al, 2009;Givnish et al, 2011;Luebert, Hilger & Weigend, 2011;Särkinen et al, 2011;Drummond et al, 2012).…”
