A new time tree reveals Earth history’s imprint on the evolution of modern birds
Estimates of the timing of evolution of modern birds reveals the influence of paleogeography and paleoclimate on diversification. Determining the timing of diversification of modern birds has beenExpand

Phylogenetic relationships among modern birds (Neornithes): towards an avian tree of life
Modem perceptions of the inonophyly of avian higher taxa {modern birds, Neomiihes) and their interrelationships are the legacy uf systematic work undertaken in the 19th century. Before LlieExpand

A palaeobiogeographic model for biotic diversification within Amazonia over the past three million years
Many hypotheses have been proposed to explain high species diversity in Amazonia, but few generalizations have emerged. In part, this has arisen from the scarcity of rigorous tests for mechanismsExpand

LINEAGE DIVERSIFICATION AND MORPHOLOGICAL EVOLUTION IN A LARGE‐SCALE CONTINENTAL RADIATION: THE NEOTROPICAL OVENBIRDS AND WOODCREEPERS (AVES: FURNARIIDAE)
Patterns of diversification in species‐rich clades provide insight into the processes that generate biological diversity. We tested different models of lineage and phenotypic diversification in anExpand

Area-relationships in the Neotropical lowlands: an hypothesis based on raw distributions of Passerine birds
Using raw geographic distributions for Neotropical species and subspecies of the perching birds (Order Passeriformes), we present an hypothesis of area- relationships for twelve avian areas ofExpand

Phylogeny and phylogenetic classification of the tyrant flycatchers, cotingas, manakins, and their allies (Aves: Tyrannides)
Phylogenetic relationships among the Tyrannides were assessed using over 4000 base pairs of nuclear recombination activating 1 (RAG‐1) and 2 (RAG‐2) DNA sequence data from about 93% of all describedExpand
