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 …

During the Pleistocene, long-term trends in global climate were controlled by orbital cycles
leading to high amplitude glacial-interglacial variability. The history of Amazonian vegetation …

The Amazonian landscape evolution is the result of the combined effect of Andean
tectonism, climate and the Earth's interior dynamics. To reconstruct the landscape evolution …

Large Amazonian rivers impede dispersal for many species, but lowland river networks
frequently rearrange, thereby altering the location and effectiveness of river barriers through …

The role of climate as a speciation driver in the Amazon has long been discussed.
Phylogeographic studies have failed to recover synchronous demographic responses …

Spatial arrangement of distinct Amazonian environments through time and its effect on
specialized biota remain poorly known, fueling long-lasting debates about drivers of biotic …

Arsenic enrichment in groundwater resources in deltas and floodplains of large sediment-
rich rivers is a worldwide natural hazard to human health. High spatial variability of arsenic …

Aim We investigate the spatiotemporal context of the diversification of Allobates, a
widespread genus of Amazonian frogs with high species diversity particularly in western …

Although vicariant processes are expected to leave similar genomic signatures among
codistributed taxa, ecological traits such as habitat and stratum can influence genetic …

Understanding the factors that govern variation in genetic structure across species is key to
the study of speciation and population genetics. Genetic structure has been linked to several …
