Una barrera importante para el avance de la ornitología es la exclusión sistémica de los
profesionales del Sur Global. Una colección especial de artículos publicada recientemente …

Aim Endemicity is one of the main indicators to describe and compare regional biotas.
Endemic species can originate from inter‐or intra‐regional speciation, but few studies have …

We examined phylogeographic patterns and cryptic diversity within the royal flycatcher,
Onychorhynchus coronatus (Aves: Onychorhynchidae), a widespread Neotropical lowland …

Our understanding of Amazonian biogeography is quickly increasing, catalyzed by the
growing use of genomic datasets, improved knowledge of species distributions, and the …

Studies about diversification of Neotropical open-habitat organisms are scarce, especially in
frogs, in which almost all studied species from Cerrado, Chaco, and Caatinga are mainly …

Aim The drivers of genetic diversity in Amazonia, the most species‐rich set of ecosystems on
Earth, are still incompletely understood. Species from distinct Amazonian ecosystems have …

The refugia hypothesis, often used to explain Amazonia's high biodiversity, initially received
ample support but has garnered increasing criticism over time. Palynological, phylogenetic …

Birds that inhabit white-sand ecosystems (WSE) in the Amazon are adapted to habitats
distributed as isolated patches. These environments occur in sandy soils that are extremely …

Speciation events occurring within biogeographic regions, and historical dispersal between
regions influence diversity patterns observed in present-day assemblages. Such …

Context Amazonian white-sand ecosystems (campinas) are open vegetation patches which
form a natural island-like system in a matrix of tropical rainforest. Due to a clear distinction …
