The timing of diversification within the most divergent parrot clade

New psittaciform DNA sequence data is examined, and previously published sequences are combined to shed light on the poorly understood timing of diversifi cation within the Strigopidae, showing a Late Pliocene or Early Pleistocene divergence between the two Nestor species.

Phylogeny and biogeography of the parrot genus Prioniturus (Aves: Psittaciformes)

According to the biogeographic reconstruction, Prioniturus has diversified by a complex combination of colonization of islands and subsequent divergence in allopatry among and within island groups and documents a rare case of faunal exchange between these two regions.

Cyclestheria hislopi (Crustacea: Branchiopoda): a group of morphologically cryptic species with origins in the Cretaceous.

Resolving a phylogenetic hypothesis for parrots: implications from systematics to conservation

An overview of published genetic data of parrots, characterise sampling depth across the phylogeny, and evaluate support for existing systematic treatments reveal well-supported relationships among recently proposed clades.

Parrot interrelationships—morphology and the new molecular phylogenies

Abstract Molecular analyses have started to provide a congruent picture of parrot interrelationships but the affinities of some taxa remain uncertain and there have been few attempts to correlate the

Model selection in statistical historical biogeography of Neotropical insects—the Exophthalmus genus complex (Curculionidae: Entiminae)

It is established that in situ diversification acts as a dominant biogeographic force in the evolution of the Exophthalmus genus complex and the colonization of the Neotropical mainland from Caribbean islands reinforces the notion that islands can be an important source of continental diversity.

Support for a phylogeny and area cladogram that does not fit a simple vicariant history for chameleons is shown, using molecular and morphological evidence for 52 chameleon taxa.

It is concluded that most of the present-day biota of Madagascar is comprised of the descendents of Cenozoic dispersers, predominantly with African origins.

A multilocus molecular phylogeny of the parrots (Psittaciformes): support for a Gondwanan origin during the cretaceous.

The results support a Cretaceous origin of Psittaciformes in Gondwana after the separation of Africa and the India/Madagascar block with subsequent diversification through both vicariance and dispersal.

Phylogeny and diversification of the largest avian radiation.

The historical framework suggests multiple waves of passerine dispersal from Australasia into Eurasia, Africa, and the New World, commencing as early as the Eocene, essentially reversing the classical scenario of oscine biogeography.

Mitochondrial and nuclear DNA sequences support a Cretaceous origin of Columbiformes and a dispersal-driven radiation in the Paleocene .

Bayesian and maximum likelihood inferences of ancestral areas, accounting for phylogenetic uncertainty and divergence times, favor an ancient origin of Columbiformes in the Neotropical portion of what was then Gondwana.

Repeated trans‐Atlantic dispersal catalysed a global songbird radiation

The data reject the alternative hypothesis that connections between Old and New World Turdus species can be attributed to movement through Beringia with subsequent extinction and suggest an increased likelihood of successfully colonizing new areas, post-dispersal.

Phylogenetic relationships and historical biogeography of neotropical parrots (Psittaciformes: Psittacidae: Arini) inferred from mitochondrial and nuclear DNA sequences.

Estimates suggest that the Neotropical parrots shared a common ancestor with Australian parrots 59 Mya, well before Australia separated from Antarctica and South America, implying that ancestral parrots were widespread in Gondwanaland, and indicated that amazons and allies are in turn a sister group to parrotlets.
