Brett Smith for redOrbit.com - Your Universe Online A report published in the journal PLOS ONE from a pair of researchers at Griffith University in Australia has refined the species status for the New Zealand moa – a large, extinct flightless bird. "Despite more than 100 years of research being devoted to the issue, determining species status is challenging, especially where there is an absence of substantial morphological, physiological, and behavioral data," explained study author...

Giant Moa Not So Giant

Brett Smith for redOrbit.com - Your Universe Online A new study of the extinct giant moa has found the massive flightless birds were actually less robust than previously believed. In the study, which was published in the journal PLOS ONE, researchers conducted computer tomography (CT) scans of full giant moa skeletons to create comprehensive digital images which were used to determine the birds' mass and general constitution. The team also scanned a smaller moa species called Pachyornis...

Extinct Moa Females Up To Three Times Larger Than Males

Brett Smith for redOrbit.com - Your Universe Online Sexual dimorphism, in which male and females of the same species differ significantly in appearance, is fairly common among birds. Typically, the male of the species either towers over the female or is equipped with elaborate plumage, as in the case of the peacock. However, for New Zealand´s extinct, flightless giant moa, the roles were reversed, with the female often weighing three times as much as her male suitors....

Birds In New Zealand Face Extinction

redOrbit Staff & Wire Reports - Your Universe Online Keys to survival today differ from those of the past. This is revealed in a new study of nearly 300 species of New Zealand birds – from pre-human times to the present. Lead author Lindell Bromham of Australian National University said, "Taking into consideration the growing number of studies that try to predict which species could be lost in the future based on what kinds of species are considered most threatened today the...

DNA recovered from fossilized bones of the moa, a giant extinct bird, has revealed a new geological history of New Zealand, reports a study published this week in the Proceedings of the National Academy of Sciences. A team of scientists led by the University of Adelaide has reconstructed a history of marine barriers, mountain building and glacial cycles in New Zealand over millions of years, using the first complete genetic history of the moa. After almost being totally submerged around 25...

Scientists have performed the first DNA-based reconstruction of the giant extinct moa bird, using prehistoric feathers recovered from caves and rock shelters in New Zealand.Researchers from the University of Adelaide and Landcare Research in New Zealand have identified four different moa species after retrieving ancient DNA from moa feathers believed to be at least 2500 years old.The giant birds - measuring up to 2.5 metres and weighing 250 kilograms - were the dominant animals in New...

A treasure trove of information about pre-human New Zealand has been found in feces from giant extinct birds, buried beneath the floor of caves and rock shelters for thousands of years. A team of ancient DNA and palaeontology researchers from the University of Adelaide, University of Otago and the NZ Department of Conservation have published their analyses of plant seeds, leaf fragments and DNA from the dried feces (coprolites) to start building the first detailed picture of an ecosystem...
