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 …

Amphibian reproductive modes (RMs) have been extensively described and applied to
amphibian biology studies. However, due to new behavioural observations and past system …

Female fecundity is an important selective force leading to female-biased sexual size
dimorphism (SSD) in frogs. Because anurans exhibit diverse reproductive modes, we …

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 …

We describe a new species of Allobates from the south of eastern Amazonia, Brazil. This
species inhabits fluvial springs and the banks of small streams in terra-firme forests along …

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 …

Despite the historical knowledge on amphibians of the Purus River basin, basic information
on assemblages is fragmented, with gaps in knowledge existing at various scales, which …
