The Rate of Extinction: 3 Species per Hour

The Rate of Extinction: 3 Species per Hour
About 6 waves of massive extinction are known in the history of the Earth. The last one wiped out the dinosaur world 65 million years ago and was probably due to a meteorite collision. But the recent one has no natural causes. It is man made and rampant, eliminating three animal or plant species every hour. Scientists and environmentalists issued reports about threats to creatures and plants including right whales, Iberian lynxes, wild potatoes and even wild peanuts. Experts gathered on May 22, at the International Day for Biological Diversity, a report on the threatened species from whales and Iberian lynxes to wild potatoes and wild peanuts. The threats to the wildlife diversity vary from habitat loss due to land clearance for farms or cities, poaching, pollution and rising human populations to global warming. determination at all levels - global, national and local," he said. UE's goal is to stop biodiversity loss by 2010, not just to slow down the process. Related:  Recent Extinctions (1600 - 2020)

11 Extinct Animals That Have Been Photographed Alive Animals Published on April 2nd, 2009 | by Bryan Nelson The current rate of extinction is 100 to 1000 times higher than the average, or background rate, making our current period the 6th major mass extinction in the planet’s history. Although fossil reconstructions or pictorial representations can sometimes be difficult to connect with, it’s impossible to ignore the experience of seeing a photograph of an animal on the brink of extinction. Thus, what follows is a list of 11 extinct animals that were photographed while still alive. Tasmanian Tiger The last Tasmanian Tiger, or Thylacine, known to have existed died in the Hobart Zoo, in Tasmania, Australia, on September 7th, 1936. Although commonly referred to as ‘tigers’, and despite having the look of a canid, the Thylacine isn’t remotely related to cats or dogs. >> Also see our latest post: 10 Animals on the Brink of Extinction Quagga Passenger Pigeon Colonial hunters happened.

Tasmanian tiger DNA 'lives' again Seventy years after the ferocious Tasmanian tiger went extinct, its marsupial DNA has been resurrected inside mice. This is the first time that genetic material from an extinct animal has functioned inside a living host. The technique has huge potential, say the researchers. For instance, it might help to reveal how dinosaurs or Neanderthals looked. Andrew Pask at the University of Melbourne, Australia, and colleagues extracted DNA from four 100-year-old Tasmanian tiger, or thylacine, samples. The samples were taken from three infant animals preserved in alcohol and one adult pelt. The DNA was badly fragmented, but the team managed to isolate one specific DNA sequence from each of the animals. Bigger questions The team then copied the DNA snippet, coupled it with a gene that produces a blue pigment, and injected it into very early mouse embryos. "We could see it very clearly in the developing cartilage," says Pask. This work isn't a step towards cloning the entire thylacine, Pask stresses.

Clouded leopard declared extinct in Taiwan Ministry of Foreign Affairs, Republic of China (Taiwan) A Formosan cloud leopard, now extinct in Taiwan. By Douglas Main, OurAmazingPlanet The Formosan clouded leopard, a clouded-leopard subspecies native to Taiwan, is now extinct, according to a team of zoologists. "There is little chance that the clouded leopard still exists in Taiwan," zoologist Chiang Po-jen told Taiwan's Central News Agency (CNA). Zoologists from Taiwan and the United States have looked for the animal on and off since 2001, to no avail. Now, the only one left in the country is a stuffed specimen at the National Taiwan Museum, zoologist Liu Jian-nan told CNA. The range of clouded leopards (Neofelis nebulosa) spans from the hills of the Himalayas to Southeast Asia to China. In 2006, research revealed that clouded leopards found in the Sunda Islands of Southeast Asia — which include Borneo, Java, Sumatra and Bali — were a separate species, now known as Sunda clouded leopards (Neofelis diardi).

A moment of silence for the Western Black Rhino Officially extinct Another beautiful species that we won't see again. The western black rhino, which is a sub-species of black rhino, was was once widespread in the savanna of sub-Saharan Africa, but no more. The last individual was spotted in 2006, and after years without any new sightings, it was officially declared extinct by the International Union for Conservation of Nature (IUCN), who maintains the famous Red List of Threatened Species. Wikimedia/Public Domain The IUCN warns that other rhinos could follow saying Africa's northern white rhino is "teetering on the brink of extinction" while Asia's Javan rhino is "making its last stand" due to continued poaching and lack of conservation." Conservation efforts certainly are not futile! Here are some black rhinos (though obviously not western black rhinos...) filmed by the BBC: Via CNN See also: Aw, cute!

Extinct frog hops back into the gene pool In what may be considered an early Easter miracle, an extinct species of native frog has begun its rise from the dead. Australian scientists have grown embryos containing the revived DNA of the extinct gastric-brooding frog, the crucial first step in their attempt to bring a species back to life. The team from the aptly named Lazarus project inserted the dead genetic material of the extinct amphibian into the donor eggs of another species of living frog, a process similar to the technique used to create the cloned sheep Dolly. Extict since 1983: The bizarre gastric-brooding frog. "This is the first time this technique has been achieved for an extinct species," said one of the project scientists, conservation biologist Michael Mahony. Advertisement While many scientists have argued it would be impossible to bring a species back from the dead like in the film Jurassic Park, the Lazarus project's breakthrough suggested the revival of extinct species was no longer the realm of science fiction.

Australian mammals on brink of extinction calamity 10 February 2015Last updated at 07:58 ET By Helen Briggs Environment Correspondent The endangered northern quoll, a mammal species native to Australia Australia has lost one in ten of its native mammals species over the last 200 years in what conservationists describe as an "extinction calamity". No other nation has had such a high rate of loss of land mammals over this time period, according to scientists at Charles Darwin University, Australia. The decline is mainly due to predation by the feral cat and the red fox, which were introduced from Europe, they say. Large scale fires to manage land are also having an impact. As an affluent nation with a small population, Australia's wildlife should be relatively secure from threats such as habitat loss. But a new survey of Australia's native mammals, published in the journal Proceedings of the National Academy of Sciences, suggests the scale of the problem is more serious than anticipated.

Elephant bird Description[edit] Size of Aepyornis maximus (centre, in purple) compared to a human, an ostrich (second from right, in maroon), and some non-avian theropoddinosaurs. Each gridline is one meter in height The elephant birds, which were giant ratites native to Madagascar, have been extinct since at least the 17th century. Étienne de Flacourt, a French governor of Madagascar in the 1640s and 1650s, mentions an ostrich-like bird said to inhabit unpopulated regions.[2] The explorer and traveler Marco Polo also mentions very large birds in accounts of his journeys to the East during the 12th and 13th centuries. These earlier accounts are today believed to describe elephant birds.[3] Aepyornis, believed to have been more than 3 m (10 ft) tall and weighing close to 400 kg (880 lb),[4] was at the time the world's largest bird. Species[edit] Genus Aepyornis Genus Mullerornis Etymology[edit] Mullerornis agilis The ancient Malagasy name for the bird is vorompatra, meaning "bird of the Ampatres".

The Sumatran rhino declared extinct in Malaysia Leading scientists and experts in the field of rhino conservation state in a new paper that it is safe to consider the Sumatran rhinoceros extinct in the wild in Malaysia. The survival of the Sumatran rhino now depends on the 100 or fewer remaining individuals in the wild in Indonesia and the nine rhinos in captivity. Despite intensive survey efforts, there have been no signs of the wild Sumatran rhinoceros (Dicerorhinus sumatrensis) in Malaysia since 2007, apart from two females that were captured for breeding purposes in 2011 and 2014. Scientists now consider the species extinct in the wild in Malaysia. The experts urge conservation efforts in Indonesia to pick up the pace. The conclusions are published online in Oryx, the International Journal of Conservation, led by the Center for Macroecology, Evolution and Climate at the University of Copenhagen.

Extinct Galapagos Giant Tortoises Could Be Brought Back To Life When Lonesome George died in 2012, it was thought that so did the last Pinta Island giant tortoise. Discovered roaming the rocky island in the Galapagos archipelago on his own in 1972, it was believed that he was the last of his subspecies. Despite a global search to find him a mate, it proved fruitless over the 80 years of his life. Now, Yale researchers think that his DNA might live on (or at least that of his relatives), diluted in hybrid tortoises found on another island descended from tortoises thrown overboard 150 years ago. The tortoises, originally found living on seven of the Galapagos Islands, are divided into 15 subspecies, of which only 11 survive to this day. Divided into two different types depending on the shape of their shell, the tortoises are known as either domed or saddlebacked. Giant galapagos turtle munching on Floreana. But how did the original purebred tortoises get so far from the islands on which they originated?

Giant Chinese paddlefish declared extinct in China Beijing — Scientists say a giant fish species that managed to survive at least 150 million years has been completely wiped out by human activity. Research published in the Science of The Total Environment this week says the giant Chinese paddlefish, also known as the Chinese swordfish, is officially extinct. The monster fish, one of the largest freshwater species in the world with lengths up to 23 feet, was once common in China's Yangtze River. Due to its speed it was commonly referred to in China as the "water tiger." Study leader Qiwei Wei of the Chinese Academy of Fishery Sciences called it "a reprehensible and an irreparable loss." Zeb Hogan, a fish expert at the University of Nevada, Reno, told National Geographic that it was "very sad" to see the "definitive loss of a very unique and extraordinary animal, with no hope of recovery." According to the researchers, no giant paddlefish have been sighted in the Yangtze since 2003, and there are none in captivity.

Great auk Extinct flightless seabird from the North Atlantic The great auk (Pinguinus impennis) is a species of flightless alcid that became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus. It is not closely related to the birds now known as penguins, which were discovered later and so named by sailors because of their physical resemblance to the great auk. It bred on rocky, isolated islands with easy access to the ocean and a plentiful food supply, a rarity in nature that provided only a few breeding sites for the great auks. The great auk was 75 to 85 cm (30 to 33 in) tall and weighed about 5 kg (11 lb), making it the largest alcid to survive into the modern era, and the second-largest member of the alcid family overall (the prehistoric Miomancalla was larger).[5] It had a black back and a white belly. The great auk was an important part of many Native American cultures, both as a food source and as a symbolic item. Taxonomy and evolution[edit] Diet[edit]
