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 …

Abstract The Caatinga of northeastern Brazil is the largest nucleus of the seasonally dry
tropical forest biome. Number of bird species in lists of the Caatinga often are quite different …

Only a fraction of species found so far has been described, particularly cryptic species
uncovered by molecular data. The latter might require the use of molecular data for its …

Determining the relative importance of dispersal and vicariance events across neotropical
regions is a major goal in biogeography. These events are thought to be related to important …

Cryptic species are a common phenomenon in cosmopolitan marine species. The use of
molecular tools has often uncovered cryptic species occupying a fraction of the geographic …

Many anuran species remain to be formally named and described in Amazonia, notably in
the Guiana Shield, and particularly in megadiverse groups such as Pristimantis. Several …

Here we describe a new species of Lancehead (Bothrops jabrensis sp. nov.) based on three
individuals sampled from a previously unknown population from Pico do Jabre, an isolated …

Sky Islands present unique landscapes for organismal evolution because they comprise
high mountain peaks separated by low valleys with vastly different environmental conditions …

Pristimantis is the most diverse Neotropical genus of terrestrial vertebrates and is distributed
from Central America to Argentina. The last few years have seen the description of several …

We describe two new species of Brazilian geckos of the genus Phyllopezus based on
morphological and molecular data. The first species is currently known from a relictual …
