In the Amazonian lowlands, the shift from a large wetland dominated by flooded forests
(Várzea) to the modern incised valleys bounded by extensive areas of non-flooded forests …

Twelve generic names have been ascribed to the New World tamarins but all are currently
placed in just one: Saguinus Hoffmannsegg, 1807. Based on geographical distributions …

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 …

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 …

Abstract Background Titi monkeys, Callicebus, comprise the most species-rich primate
genus—34 species are currently recognised, five of them described since 2005. The lack of …

To determine the effect of rivers, environmental conditions, and isolation by distance on the
distribution of species in Amazonia. Location: Brazilian Amazonia. Time period: Current …

The squirrel monkey, Saimiri, is a pan-Amazonian Pleistocene radiation. We use statistical
phylogeographic methods to create a mitochondrial DNA-based timetree for 118 squirrel …

Aim Our aim was to investigate how the distance to water (flooding gradients) and riverine
barriers (Tapajós and Jamanxim rivers) influence the distributional patterns of amphibian …

Climate change will redistribute the global biodiversity in the Anthropocene. As climates
change, species might move from one place to another, due to local extinctions and …

Wallace's riverine barrier hypothesis postulates that large rivers, such as the Amazon and its
tributaries, reduce or prevent gene flow between populations on opposite banks, leading to …
