Despite the impressive growth of knowledge on the phylogenetic systematics of dart-poison
frogs and their relatives (Dendrobatoidea) over the past decade, many problems remain to …

Rising habitat loss is one of the main drivers of the global amphibian decline. Nevertheless,
knowledge of amphibian diversity needed for effective habitat protection is still highly …

ABSTRACT The Acoustic Adaptation Hypothesis (AAH) predicts that acoustic signals
emitted at sites with greater vegetation density should have spectral and temporal …

In the Amazon basin, the distribution of many vertebrate species is delimited by large rivers,
which are frequently considered as biogeographical barriers strongly related to the origin …

The small size, low vagility, territoriality, and reproductive mode of some Amazonian frogs
undermine the wide geographical distribution assigned to them. Species with these features …

The Amazon basin region, which harbors the largest river system in the world, and which is
drained by the Amazon River, has experienced several geomorphological and climatic …

Cryptic diversity is extremely common in widespread Amazonian anurans, but especially in
nurse frogs of the genus Allobates. There is an urgent need to formally describe the many …

Limited knowledge about species diversity restricts inferences about biogeography and
macroecology in Amazonia, where biodiversity documentation has become particularly …

The small nurse frogs of the genus Allobates (Anura, Aromobatidae) represent one of the
most challenging taxonomic issues of the Neotropics. During several amphibian surveys in …

The use of acoustic signals is a common characteristic of most anuran species to mediate
intraspecific communication. Besides many social purposes, one of the main functions of …
