Amazonia (defined herein as the Amazon basin) is home to the greatest concentration of
biodiversity on Earth, providing unique genetic resources and ecological functions that …

A phylogenetic analysis of sequences from 503 species of hylid frogs and four outgroup taxa
resulted in 16,128 aligned sites of 19 genes. The molecular data were subjected to a …

Molecular data have been used to date species divergences ever since they were described
as documents of evolutionary history in the 1960s. Yet, an inadequate fossil record and …

Testing hypotheses on drivers of clade evolution and trait diversification provides insight into
many aspects of evolutionary biology. Often, studies investigate only intrinsic biological …

Anolis lizards (anoles) are textbook study organisms in evolution and ecology. Although
several topics in evolutionary biology have been elucidated by the study of anoles, progress …

Glassfrogs (family: Centrolenidae) represent a fantastic radiation (~ 150 described species)
of Neotropical anurans that originated in South America and dispersed into Central America …

The tropical Andes are an important natural laboratory to understand speciation in many
taxa. Here we examined the evolutionary history of parasites of the Leishmania braziliensis …

Many animals provide parental care to offspring. Parental sex‐roles vary extensively across
taxa, and such patterns are considered well documented. However, information on …

Despite the recent advances in the systematics of snakes, the diversity of several
Neotropical groups of species remains poorly understood. The lack of studies focused on …

The Neotropics harbour the most diverse flora and fauna on Earth. The Andes are a major
centre of diversification and source of diversity for adjacent areas in plants and vertebrates …
