The history of Psophia, in combination with new geological evidence, provides the strongest direct evidence supporting a role for river dynamics in Amazonian diversification, and the absence of such a roles for glacial climate cycles and refugia.

It is found that the Furnariidae exhibit nearly constant rates of lineage accumulation but show evidence of constrained morphological evolution, suggesting that lineage accumulation in tropical continental radiations may not be as limited by ecological opportunities as in temperate or island radiations.
The drivers of tropical speciation
It is shown that spatial and temporal patterns of genetic differentiation in Neotropical birds are highly discordant across lineages and are not reconcilable with a model linking speciation solely to landscape change, and the strongest predictors of speciation are the amount of time a lineage has persisted in the landscape and the ability of birds to move through the landscape matrix.

Important predictions of both riverine barrier and Miocene marine incursion hypotheses were supported, indicating that they are not mutually exclusive; in fact, the data presented herein suggest that an interaction among geology, sea level changes, and hydrography created opportunities for cladogenesis in the X. spixiilelegans superspecies at different temporal and geographical scales.
Annotated checklist of the birds of Brazil by the Brazilian Ornithological Records Committee / Lista comentada das aves do Brasil pelo Comitê Brasileiro de Registros Ornitológicos
For the first time, all bird subspecies known from Brazil that are currently accepted by at least one key ornithological reference work are listed.

Recon reconstructing passerine evolutionary history and producing the most comprehensive time-calibrated phylogenetic hypothesis of the group, which suggests more complex mechanisms than temperature change or ecological opportunity have controlled macroscale patterns of passerine speciation.

Abstract Among those few hypotheses of Amazonian diversification amenable to falsification by phylogenetic and population genetics methods, three can be singled out because of their general…
Effects of palm heart harvesting on avian frugivores in the Atlantic rain forest of Brazil
This result indicates that Euterpe palms in the lowland forests do not fulfil the role of keystone species, because they bear ripe fruits during the period of peak overall fruit availability and because birds may switch their diets to other food sources when palms are removed.
Phylogeography of the chestnut‐tailed antbird (Myrmeciza hemimelaena) clarifies the role of rivers in Amazonian biogeography
The findings implicate rivers as barriers driving diversification in the M. hemimelaena complex, and underscore the pervasiveness of cryptic endemism throughout Amazonia and the importance of DNA-based taxonomic and phylogeographic studies in providing the accurate estimates of diversity that are essential for conservation planning.
