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 …

Integration of regional stratigraphic relationships with data on sediment accumulation,
provenance, paleodrainage, and deformation timing enables a reconstruction of Mesozoic …

We provide a general compilation of the diversity and geographical distribution of
Amazonian fishes, updated to the end of 2018. Our database includes documented …

The fish faunas of continental South and Central America constitute one of the greatest
concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living …

• Premise: Bromeliaceae form a large, ecologically diverse family of angiosperms native to
the New World. We use a bromeliad phylogeny based on eight plastid regions to analyze …

Many hypotheses have been proposed to explain high species diversity in Amazonia, but
few generalizations have emerged. In part, this has arisen from the scarcity of rigorous tests …

We review geological evidence on the origin of the modern transcontinental Amazon River,
and the paleogeographic history of riverine connections among the principal sedimentary …

On the basis of paleontological content (vertebrates and palynology) and facies analysis
from river banks, road cuts, and three wells, we have assigned the uppermost levels of the …

Patterns of diversification in species‐rich clades provide insight into the processes that
generate biological diversity. We tested different models of lineage and phenotypic …

The Amazon submarine fan is a large sediment apron situated offshore Pará (Brazil) and
represents the most distal extent of the Amazon River. The age of onset of this …
