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

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 …

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

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

In cryptic amphibian complexes, there is a growing trend to equate high levels of genetic
structure with hidden cryptic species diversity. Typically, phylogenetic structure and distance …

Amphibians are characterized both by a strongly increasing number of newly discovered
species and by a high degree of decline. The observed increase in species numbers, over …

Few studies to date have examined genetic variability of widespread tropical amphibian
species over their distributional range using different kinds of molecular markers. Here, we …

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 …

Morphologically cryptic species act as a wild card when it comes to biodiversity assessments
and conservation, with the capacity to dramatically alter our understanding of the biological …

Background The forests of the upper Amazon basin harbour some of the world's highest
anuran species richness, but to date we have only the sparsest understanding of the …
