The Neotropics contains half of remaining rainforests and Earth's largest reservoir of
amphibian biodiversity. However, determinants of Neotropical biodiversity (ie, vicariance …

Aim We investigate the spatiotemporal context of the diversification of Allobates, a
widespread genus of Amazonian frogs with high species diversity particularly in western …

Abstract Aim Mapping Amazonian biodiversity accurately is a major challenge for integrated
conservation strategies and to study its origins. However, species boundaries and their …

Aim For many taxa, inaccuracy of species boundaries and distributions hampers inferences
about diversity and evolution. This is particularly true in the Neotropics where prevalence of …

Abstract Aim The Caatinga is a widespread but poorly known biome in South America. Its
historical stability is controversial and different types of evidence provide support to …

Abstract The Guiana Shield (GS) is one of the most pristine regions of Amazonia and
