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

Background Amphibians are rapidly vanishing. At the same time, it is most likely that the
number of amphibian species is highly underestimated. Recent DNA barcoding work has …

One of the greatest challenges for biodiversity conservation is the poor understanding of
species diversity. Molecular methods have dramatically improved our ability to uncover …

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

Lack of resolution on species boundaries and distribution can hamper inferences in many
fields of biology, notably biogeography and conservation biology. This is particularly true in …

Several hypotheses have been proposed to explain the biogeographic processes that
generate the high species richness of the Amazon basin. We tested two of them in a terra …

Pluralistic approaches to taxonomy facilitate a more complete appraisal of biodiversity,
especially the diversification of cryptic species. Although species delimitation has …

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 …

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

Species distributed across vast continental areas and across major biomes provide unique
model systems for studies of biotic diversification, yet also constitute daunting financial …
