Brachycephaloidea is a monophyletic group of frogs with more than 1000 species
distributed throughout the New World tropics, subtropics, and Andean regions. Recently, the …

Frogs are ideal organisms for studying sex chromosome evolution because of their diversity
in sex chromosome differentiation and sex-determination systems. We review 222 anuran …

Background and Research Aims: Globally, Colombia is the country with the largest extent of
Páramos (delimited in 36 complexes) and with the greatest number of amphibian species in …

While global amphibian declines are associated with the spread of Batrachochytrium
dendrobatidis (Bd), undetected concurrent co-infection by other pathogens may be little …

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

Comparative phylogeography allow us to understand how shared historical circumstances
have shaped the formation of lineages, by examining a broad spectrum of co-distributed …

Genomics has great potential to advance understanding of amphibian evolution, ecology,
and behavior, as well as to improve conservation of this highly imperiled class of …

Geographic barriers and elevational gradients have long been recognized as important in
species diversification. Here, we illustrate an example where both mechanisms have …

The geology of the northern Andean region has driven the evolutionary history of
Neotropical fauna through the creation of barriers and connections that have resulted in …

Although biodiversity gradients have been widely documented, the factors governing broad‐
scale patterns in species richness are still a source of intense debate and interest in …
