Diversification and phenotypic evolution in Neotropical amphibians



Amphibians represent nearly 15% of known vertebrate diversity and include more than 6300 described species. Although roughly 50% of the planet’s amphibians inhabit the American tropics, little is known about the factors that influence tropical diversity patterns. This lack of knowledge becomes increasingly alarming as it has been estimated that nearly one third of amphibian species are threatened with extinction.

In this research line we combine modern phylogenetic, biogeographic, comparative and genomic methods to examine the intrinsic and extrinsic drivers of diversification and phenotypic evolution of Neotropical amphibians at both a micro- and macro-evolutionary scale, providing an essential step forward in the understanding of global diversity patterns.






Carles Vilà is leading this project, which is a collaborative effort.

Álvaro Dugo-Cota and Santiago Montero-Mendieta are two PhD students working on this research line.

Some of our collaborators are:
José Manuel Padial, Carnegie Museum of Natural History (USA)
Santiago Castroviejo-Fisher, Pontifícia Universidade Católica do Rio Grande do Sul (Brasil)
Matthew Webster, Uppsala University (Sweden)
Alejandro Gonzalez-Voyer, Universidad Nacional Autónoma de México (Mexico)
Ignacio de la Riva, National Museum of Natural Sciences - Spanish National Research Council (CSIC) (Spain)
Ariel Rodriguez, Technical University of Braunschweig (Germany)



You can watch how
José Manuel Padial and his team go on a scientific expedition to obtain samples for further analyses.
