The American tropics (the Neotropics) are the most species-rich realm on Earth, and for
centuries, scientists have attempted to understand the origins and evolution of their …

INTRODUCTION Individual processes that shape geographical patterns of biodiversity are
increasingly understood, but their complex interactions on broad spatial and temporal scales …

Abstract The South American Dry Diagonal, also called the Diagonal of Open Formations, is
a large region of seasonally dry vegetation extending from northeastern Brazil to northern …

We studied the phylogeny, biogeography, and diversification of suboscine passerines in the
genus Scytalopus (Rhinocryptidae), a widespread, species-rich, and taxonomically …

The Neotropical region is the most diverse on the planet, largely owing to its mosaic of
tropical rainforests. Multiple tectonic and climatic processes have been hypothesized to …

Simple Summary Recognizing the different species can help us better understand the
nature. One way to differentiate bird species is the bird song. There are mathematical …

In this paper we present a phylogenetic analysis of the treefrogs of the Boana pulchella
Group with the goals of (1) providing a rigorous test of its monophyly;(2) providing a test of …

We evaluated whether the Andean and the Atlantic forests acted as refugia during the
Quaternary, and tested biogeographic hypotheses about the regions involved in the …

Some phylogenetic problems remain unresolved even when large amounts of sequence
data are analyzed and methods that accommodate processes such as incomplete lineage …

Regional species diversity is explained ultimately by speciation, extinction and dispersal.
Here, we estimate dispersal and speciation rates of Neotropical butterflies to propose an …
