Giant tortoise makes 'miraculous' stable recovery

Where once there were 15, now more than 1,000 giant tortoises lumber around Espanola, one of the Galapagos Islands.
After 40 years' work reintroducing captive animals, a detailed study of the island's ecosystem has confirmed it has a stable, breeding population.

Lonesome George's genetic legacy survives as scientists uncover Pinta Tortoise hybrids in the Galapagos Islands

Scientists have discovered several giant tortoises with partial Pinta Island ancestry on Isabela Island in the Galapagos Islands. The death of Lonesome George, the last known pure Pinta Island Giant Tortoise (Chelonoidis abingdoni), on June 24, 2012, may not have signalled the end of his species.

Lonesome George

Spoiler

Lonesome George the last of the species from la Pinta Island died June 24 2012. A video from May 17 2012 shows George in the Charles Darwin research foundation.

Last Pinta giant tortoise Lonesome George dies

Staff at the Galapagos National Park in Ecuador say Lonesome George, a giant tortoise believed to be the last of its subspecies, has died.
Scientists estimate he was about 100 years old.

'Extinct' Galapagos tortoise may still exist

A giant Galapagos tortoise believed extinct for 150 years probably still exists, say scientists.
Chelonoidis elephantopus lived on the island of Floreana, and was heavily hunted, especially by whalers who visited the Galapagos to re-stock.
A Yale University team found hybrid tortoises on another island, Isabela, that appear to have C. elephantopus as one of their parents.
Some hybrids are only 15 years old, so their parents are likely to be alive.

Genetic Analysis Gives Hope That Extinct Tortoise Species May Live Again

Thanks to genetic data gleaned from the bones found in a several museum collections, an international team of researchers led by scientists from Yale believes it may be possible to resurrect a tortoise species hunted to extinction by whalers visiting the Galapagos Islands during the early 19th century, before Charles Darwin made his famous visit.
A genetic analysis of 156 tortoises living in captivity and the DNA taken from remains of specimens of the now-extinct Chelonoidis elephantopus revealed that nine are descendents of the vanished species, which once made its home on Floreana Island in the Galapagos. Over a few generations, a selective breeding program among these tortoises should be able to revive the C. elephantopus species, said Adalgisa Caccone, senior research scientist in the department of ecology and evolutionary biology at Yale and senior author of the piece published this week in the online journal PLoS ONE.

Lonesome George at the Charles Darwin Research Station. "Lonesome George," a giant Galapagos tortoise and conservation icon long thought to be the sole survivor of his species, may not be alone for much longer, according to a multinational team of researchers headed by investigators at Yale University.
Lonesome George, a native of Pinta, an isolated northern island of the Galápagos, is the "rarest living creature." By the late 1960s, it was noted that the tortoise population on this island that is visited only occasionally by scientists and fishermen, had dwindled close to extinction, and in 1972, only this single male of the species Geochelone abingdoni was found.
Population analyses of a large database including individuals from all 11 existing species of Galápagos tortoises was compared to the genetic variation within two of the G. becki populations. DNA data for the nearly extinct G. abingdoni species from Pinta was available for the first time from six museum specimens -- and from Lonesome George.
There are well over 2,000 tortoises of G. becki living on the neighbouring volcanic Isabela Island, which has only two sites accessible from the sea. The research team collected samples from a total of 89 tortoises -- 29 at one location, 62 on the other side of the island. Because the subset of the population they sampled was so small, the researchers hope that thorough sampling will locate a genetically pure Pinta tortoise.
