The Amazonian rainforest is arguably the most species-rich terrestrial ecosystem in the
world, yet the timing of the origin and evolutionary causes of this diversity are a matter of …

Lower C entral A merica (LCA) provides a geologically complex and dynamic, richly
biodiverse model for studying the recent assembly and diversification of a N eotropical biota …

Modern attempts to produce biogeographic maps focus on the distribution of species, and
the maps are typically drawn without phylogenetic considerations. Here, we generate a …

Species are the fundamental units of biology, ecology and conservation, and progress in
these fields is therefore hampered by widespread taxonomic bias and uncertainty …

There is much evidence to support past contact between the Atlantic and the Amazon forests
through the South American dry vegetation diagonal, but the spatiotemporal dynamics of this …

The Amazon River and its major tributaries delimit the distributions of hundreds of terrestrial
taxa. It remains unclear whether river-bounded distributions and taxon replacements reflect …

Evaluar las especies endémicas y casi-endémicas de un país es una herramienta
importante y complementaria para identificar y determinar prioridades de conservación y …

Recent studies have increasingly implicated deep (pre-Pleistocene) events as key in the
vertebrate speciation, downplaying the importance of more recent (Pleistocene) climatic …

Abstract The Guiana Shield (GS) is one of the most pristine regions of Amazonia and
biologically one of the richest areas on Earth. How and when this massive diversity arose …

Andean uplift contributed importantly to the build‐up of high Neotropical diversity. Final uplift
of the Eastern Cordillera of Colombia separated once‐contiguous lowland faunas east and …
