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 …

▪ Abstract As better phylogenetic hypotheses become available for many groups of
organisms, studies in community ecology can be informed by knowledge of the evolutionary …

High species diversity may result from recent rapid speciation in a 'cradle'and/or the gradual
accumulation and preservation of species over time in a 'museum',. China harbours nearly …

Far from a uniform band, the biodiversity found across Earth's tropical moist forests varies
widely between the high diversity of the Neotropics and Indomalaya and the relatively lower …

Introduction Recent decades have seen a major international effort to inventory tree
communities in the Amazon Basin and Guiana Shield (Amazonia), but the vast extent and …

Summary The tropical Andes of South America, the world's richest biodiversity hotspot, are
home to many rapid radiations. While geological, climatic, and ecological processes …

Understanding the processes that cause speciation is a key aim of evolutionary biology.
Lineages or biomes that exhibit recent and rapid diversification are ideal model systems for …

Forest structure and dynamics vary across the Amazon Basin in an east-west gradient
coincident with variations in soil fertility and geology. This has resulted in the hypothesis that …

Abstract The Neotropical region (tropical America) is the most species rich region on Earth.
Several causes have been proposed to explain this extraordinary biodiversity, which may be …
