The flight of the Passenger Pigeon: phylogenetics and biogeographic history of an extinct species.

چکیده
The human-caused extinction of the Passenger Pigeon (Ectopistes migratorius) is one of the best known and documented of any bird. This event was particularly alarming because the Passenger Pigeon went from being one of the most numerous avian species in the world to extinct in a period of decades, when the last individual died in captivity in a Cincinnati Zoo in 1914. While a great deal of information exists on the likely direct and indirect causes of its demise, as well as information on life-history, the phylogenetic relationships of this species have been subject to considerable speculation. Here we use DNA sequences obtained from museum specimens to resolve the phylogenetic position of this species with respect to other pigeons and doves (Columbiformes). We show that the Passenger Pigeon is not related to the New World mourning doves (Zenaida) as many authors have suggested, but is the sister taxon of all other New World pigeons (Patagioenas). Biogeographic analysis suggests the Passenger Pigeon lineage may have colonized North America from Asia, and subsequently dispersed into South America, leading to a more extensive radiation of New World pigeons.

The Passenger Pigeon (Ectopistes migratorius) was an iconic species of bird in eastern North America that comprised 25-40% of North American avifauna. Passenger Pigeons went extinct in 1914 due to excessive hunting over the previous 50 years. Current research aims to de-extinct the Passenger Pigeon and someday release the species into its historic range. To determine under which conditions a Pa...

The information from ancient DNA (aDNA) provides an unparalleled opportunity to infer phylogenetic relationships and population history of extinct species and to investigate genetic evolution directly. However, the degraded and fragmented nature of aDNA has posed technical challenges for studies based on conventional PCR amplification. In this study, we present an approach based on next generat...

Passenger Pigeons (Ectopistes migratorius) were once the most abundant bird in North America, with flock sizes estimated in the billions. However, by the turn of the 20th century, this previously abundant species had been driven to extinction. Morphological analyses linked the Passenger Pigeon with the New World mourning doves of the genus Zenaida. However, mitochondrial analyses strongly suppo...

Campanulotes flavus (Rudow, 1869) from Phaps chalcoptera is redescribed and illustrated. C. defectus Tendeiro, 1969, erroneously recorded from the extinct passenger pigeon Ectopistes migratorius, is shown to be a junior synonym of C. flavus, thus removing it from the list of lice thought to have gone extinct with the passenger pigeon. C. flavus elegans (Tendeiro, 1978) from P. elegans is elevat...
