Phylogenomics has revealed the remarkable frequency with which introgression occurs
across the tree of life. These discoveries have been enabled by the rapid growth of methods …

The origin, distribution, and function of biological diversity are fundamental themes of
ecology and evolutionary biology. Research on birds has played a major role in the history …

An updated version of the checklist of birds of Brazil is presented, along with a summary of
the changes approved by the Brazilian Ornithological Records Committee's Taxonomy …

Human impact is noticeable around the globe, indicating that a new era might have begun:
the Anthropocene. Continuing human activities, including land‐use changes, introduction of …

Most species are extinct, those that are not are often unknown. Sequenced and sampled
species are often a minority of known ones. Past evolutionary events involving horizontal …

Background Hybridisation and introgression play key roles in the evolutionary history of
animal species. They are commonly observed within several orders in wild birds. The …

Behavioral changes, such as those involved in mating, foraging, and migration, can
generate reproductive barriers between populations. Birds, in particular, are known for their …

Evolution is a continuous trial and error process in which most lineages go extinct without
leaving fossil remains. Many of these lineages would be closely related and occasionally …

Phylogenetic trees based on genome-wide sequence data may not always represent the
true evolutionary history for a variety of reasons. One process that can lead to incorrect …

The translocation of individuals around the world is leading to rising incidences of
anthropogenic hybridization, particularly between domestic and wild congeners. We apply a …
