    Poachers push 2 Madagascar tortoises to brink

    Turtle Conservancy

    The ploughshare tortoise, found only in Madagascar, is being collected out of existence by illegal wildlife traffickers.

    By Douglas Main
    LiveScience

    Things just got much worse for two critically endangered tortoise species in Madagascar. Illegal poaching is "raging out of control" and pushing radiated and ploughshare tortoises to the brink of extinction, according to a statement from the Wildlife Conservation Society (WCS).

    More than 1,000 of the animals have been confiscated from smugglers in the first three months of 2013 alone, the environmental group reported. A total of 54 ploughshare tortoises were intercepted in Thailand, and the species is "now the most common tortoise for sale in Bangkok's infamous Chatuchak wildlife market," according to the statement.

    The ploughshare tortoise was once common in northern Madagascar but as of 2008 it was estimated that there were only 400 left in the wild, according to the International Union for Conservation of Nature. These reptiles can grow up to 19 inches (47 centimeters) long and weigh up to 42 pounds (19 kilograms).

    The radiated tortoise has disappeared from wide areas of its native habitat in southern Madagascar due to hunting for food and the illegal pet trade.

    The radiated tortoise lives in the country's south. Its dark brown or black domed shell is covered with bright yellow or orange starlike patterns and can grow up to 16 inches (40 cm) long. They can live for an estimated 100 years, according to the IUCN.

    "These tortoises are truly one of Madagascar's most iconic species," James Deutsch, executive director of the Africa Program at WCS, said in the statement. "This level of exploitation is unsustainable. Unless immediate action is taken to better protect the wild populations, their extinction is imminent."

    Due to their unique beauty, many of the animals are taken for the illegal pet trade. Illegal poaching and smuggling has increased about tenfold since Madagascar's political crisis began in 2009, accompanied by eroded law and order, the WCS said. In the past, it was considered taboo to harm the tortoises, although this tradition has faded with years of drought and increasing poverty, according to the statement.

    Embryos of world's most endangered cat preserved

    Iberian Lynx Conservation Breeding Program

    The Iberian lynx is the most endangered wild cat species worldwide.

    By Megan Gannon
    LiveScience

    It seems counterintuitive that castration could help save a species facing extinction. But through removing the ovaries of a female Iberian lynx, scientists say they were able to collect and preserve embryos from the world's most endangered wild cat for the first time.

    Conservationists are hoping the fertilized eggs could be implanted into a surrogate mother of a closely related species, possibly a Eurasian lynx female. Even one successful surrogate pregnancy could be a boost for felines, whose declining population had been estimated to be less than 200 a decade ago.

    One Iberian lynx named Azahar, which was part of a breeding program in Silves, Portugal, had problems giving birth and underwent two emergency Caesarean sections in two consecutive pregnancies. Conservationists decided that, for health reasons, they shouldn't try breeding Azahar again and the cat's ovaries were removed by castration.

    But immediately after Azahar's castration surgery, scientists say they obtained embryos and ovarian pieces from the feline in a process adapted from one used on domestic cats. [Feline Fun! 10 Amazing Facts About Cats]

    "Seven days after mating we expected to flush embryos from the uterus," Katarina Jewgenow, a specialist from the Leibniz Institute for Zoo and Wildlife Research (IZW) in Berlin, said in a statement. But instead, the oocytes (unfertilized eggs) and embryos had to be flushed out of the oviducts. This told the team something new about Iberian lynxes — their embryos develop more slowly than those of domestic cats.

    The group of specialists also intervened when scientists decided to castrate a female Iberian lynx in captivity in Doñana, Spain. Named Saliega, this cat was relatively old (12 years), already gave birth to 16 cubs, and developed a mammary tumor last summer after her last lactating period.

    "From her we only flushed unfertilized eggs, thus the male was not fertile," Natalia Mikolaewska, an IZW doctoral student, said in a statement. But the team was at least able to recover and freeze those oocytes, which could later be fertilized and implanted in a surrogate.

    "The next step we are discussing right now is to implant these embryos into a foster mother, which might be an Eurasian lynx female," said Jewgenow.

    The Iberian lynx is the only wild cat to be listed as critically endangered by the International Union for Conservation of Nature (IUCN) and IZW is working with the Iberian lynx Conservation Breeding Program to help save them.

    If reviving a dying species sounds ambitious, consider the scientists who are trying to bring back animals that are already extinct. Biologists did actually resurrect the extinct Pyrenean ibex in 2003 by creating a clone from a frozen tissue sample harvested before the goat's entire population vanished in 2000. But that clone survived for only a few minutes after birth. Researchers gathered in Washington, D.C., on March 15 for a forum called TEDxDeExtinction, hosted by the National Geographic Society, to dive into some of the practical and ethical questions surrounding current efforts to revive animals that have been dead for much longer than the Pyrenean ibex, such as the passenger pigeon and woolly mammoth.

    International shark trade regulations backed

    Wayne Davis

    On Aug. 22, 2012, fish spotter Wayne Davis found this school of 20 scalloped hammerhead sharks above Oceanographer's Canyon, 100 miles southeast of Nantucket, Mass.

    By Megan Gannon
    LiveScience

    Conservationists voted Monday to regulate the international trade of five species of sharks that are threatened by overfishing and targeted for their valuable fins.

    Oceanic whitetip sharks, porbeagle sharks, scalloped hammerheads, great hammerheads and smooth hammerheads — as well as two species of manta rays — are set to get new protections after this week's votes at the meeting of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in Bangkok.

    If the proposals are upheld at a plenary session later this week, all seven animals will be listed under Appendix II of the CITES Treaty, which includes species that may become threatened with extinction if they are traded unsustainably. So far, basking sharks and great white sharks are the only species of elasmobranch (a family that includes sharks, rays and skates) listed on Appendix II.

    Sharks are apex predators that help balance ecosystems in the world's oceans, and they have slow growth and reproductive rates, making it difficult for their populations to bounce back from big losses. The votes at CITES were applauded by conservationists and biologists who say overfishing is by far the biggest pressure faced by sharks. [On the Brink: A Gallery of Wild Sharks]

    The fish are harvested for their meat, liver oil and cartilage, as well as their fins, which are cut off to be used in shark fin soup, an ancient and prized delicacy in East Asia. According to the World Wildlife Fund, a shark's fin can sell for up to $135/kg in Hong Kong.

    "That market has created a lot of demand for shark fins and even spawned a brutal practice in some fishing communities called 'finning,' in which sharks have their fins cut off (the most valuable part) and are then thrown back alive but finless, where they most certainly die," Alistair Dove, a marine scientist at the Georgia Aquarium, told LiveScience in an email. "Manta rays are facing a similar challenge, except that in those species it is the gill rakers that have developed a market for use in Chinese traditional medicine, leading to unsustainable harvest of those peaceful and graceful plankton feeders."

    David Shiffman, a shark biologist, told LiveScience that for the species what will be covered under the new CITES listing, "a lot of the trade is largely unregulated and it's led to massive population declines, particularly for hammerheads and oceanic whitetips."

    Though the decline of shark populations has been documented, scientists don't have great data on how bad the problem is since unregulated and illegal catches often go unreported. A study out earlier this month estimated that about 100 million sharks are killed each year, but researchers said the real number of annual shark deaths could fall in a rather large range, between 63 million and 273 million. Shiffman was hopeful that more regulation will give scientists a better idea of the numbers.

    "This will lead to additional data about the harvest of these species, which will allow us to make more informed management decisions in the future," Shiffman said. "More data is always better for science."

    To help drum up support for shark-protecting proposals, the U.S. delegation to CITES says it worked with other countries, including Brazil, Colombia, the European Union, Costa Rica, Honduras, Ecuador, Mexico and Egypt.

    "We are extremely pleased that CITES member nations have given greater protections to these commercially exploited marine species," Bryan Arroyo, head of the U.S. delegation, said in a statement. "Through the cooperation of the global community, we can begin addressing the threats posed by unsustainable global trade in shark fins and other parts and products of shark and ray species."

    The CITES Treaty is signed by 178 countries, and a meeting is held every two to three years to review and negotiate changes to the international trade of species covered by the agreement. Whereas sharks fared well during this year's meeting, another highly anticipated proposal to ban the trade of polar bear hides and parts was shot down.

    So, no pun intended, but does this treaty protecting sharks have teeth? What's to stop the nations that benefit most from the fishing from just ignoring it and trading anyway? Also, it seems like this treaty only targets international trade in these species. Does this effect purely domestic fishing  …

    Syrian violence threatens ancient treasures

    Reuters file

    People shop at the main market, or souk, in the Syrian city of Aleppo.

    By Reuters

    AMMAN — Syrian museums have locked away thousands of ancient treasures to protect them from looting and violence but one of humanity's greatest cultural heritages remains in grave peril, the archaeologist charged with their protection said.

    Aleppo's medieval covered market has already been gutted by fires which also ripped through the city's Umayyad mosque. Illegal excavations have threatened tombs in the desert town of Palmyra and the Bronze Age settlement of Ebla, and Interpol is hunting a 2,700-year-old statue taken from the city of Hama.

    In a country which also boasts stunning Crusader castles, Roman ruins and a history stretching back through the great empires of the Middle East to the dawn of human civilization, the task of safeguarding that heritage from modern conflict is a daunting responsibility.

    Maamoun Abdulkarim, head of Syria's antiquities and museums, says it is a battle for the nation's very existence.

    "We emptied Syria's museums. They are in effect empty halls, with the exception of large pieces that are difficult to move," Abdulkarim told Reuters during a visit to neighboring Jordan.

    Tens of thousands of artifacts spanning 10,000 years of history were removed to specialist warehouses to avoid a repeat of the storming of Baghdad's museum by looters a decade ago, in the wake of the U.S. invasion and overthrow of Iraqi President Saddam Hussein, he said.

    Syria's own 23-month-old conflict is tearing the country apart and has raised international concerns over the fate of one of the richest and most diverse historical collections of any single nation.

    The UN cultural body UNESCO says it is concerned for the fate of six World Heritage sites including the old cities of Damascus, Aleppo and Bosra and the imposing Crusader castle, Crac des Chevaliers.

    Many have become battlegrounds between rebels taking cover among ruins and troops who shell indiscriminately, the damage recorded in relentless video images of the fighting.

    If looters ever got their hands on the museum treasures, that would mark the final demise of Syria, Abdulkarim said.

    "If they reach these places then my conviction is that Syria would no longer exist... It would signal the end of the end," said the 46-year-old French-educated archaeology professor who took over as Syria's Director General of Antiquities and Museums six months ago. "Syria as we know it would then be over."

    Bronze statue
    Numerous Bronze Age civilizations left successive marks on Syria including Babylonians, Assyrians, and Hittites. They in turn were replaced by Greeks, Sassanians, Persians, Romans and Arabs, many choosing Syrian cities for their capitals.

    European Crusaders left impressive castles and the Ottoman Empire also made its mark over five centuries.

    Abdulkarim said the most significant pieces to go missing since the start of the conflict were a gilt bronze statue from around 2,000 years ago that was stolen from the city of Hama — and placed on Interpol's 'Most Wanted' list of art works a year ago - and a marble piece looted from the garden of Apamea museum.

    But priceless artifacts in the northern town of Maarat al-Noman were saved when the local community ensured the museum's famous mosaic portals were kept safe during fierce clashes.

    In Hama, local neighborhood youths protected the museum's Roman and Byzantine statues from looters until they were taken to safety, Abdulkarim said. "They closed the doors of the museum and were able to protect it from disaster."

    Dozens of archaeological sites have been targeted by illegal excavation and trafficking, though they account for less than 1 percent of the 10,000 sites across the country, he said.

    The diggers concentrate mainly on sites which have long been the focus of illicit trafficking, such as the ancient city of Apamea, north of Hama, that flourished during Roman and Byzantine periods, and is famous for its 1,850-metre colonnade.

    "Vandalism in the city is an old phenomenon and is not related to the crisis, but the thieves who are active in this area have found greater freedom to operate during this crisis," Abdulkarim said.

    Video footage from March last year, documented in a report by archaeologist Emma Cunliffe at Britain's Durham University, also appears to show tanks stationed alongside the Apamea colonnade.

    Abdulkarim appealed to the warring parties to spare the country's many Crusader castles, some of which have been in the thick of the conflict and even been converted into army barracks or rebel hideouts.

    Crac des Chevaliers, the supreme example of Crusader castle building, has suffered minor damage while Aleppo citadel's main gate was sightly damaged along with its northern tower, he said.

    Gutted souks
    The greatest damage has been to a collection of seven old markets in Aleppo, unsurpassed in the Middle East, that were gutted by fire that also damaged the city's Great Umayyad Mosque, Abdulkarim said.

    "We have lost the seven souks completely, forever," he said, although the continued fighting had prevented any mission from assessing the full extent of the structural damage.

    In northeastern Syria, major ancient sites in Tell Mozan near Qazmishli were well protected by Kurdish groups that have taken control in the region, Abdulkarim said.

    U.S. historian Giorgio Buccellati, who has worked at Tell Mozan and checks photos of the site daily on the Internet, told Reuters there had been "absolutely no looting" there.

    In southern Syria, army shelling had damaged some ancient homes but not the ruin of Bosra, which contains one of the best preserved Roman theaters and a major monument, Abdulkarim said. His comments were confirmed by a refugee who spoke to Reuters this week after fleeing the town.

    "The army had shelled the old quarter where rebels had dug in and there has been damage to an old church," Abdullah Zubi said after crossing into Jordan. But the Roman theater, in an army-controlled sector, suffered no damage although army troops are dug in nearby, he said.

    The ruins of what may be the world's first city, a mound near the Syrian-Iraqi border town called Tell Brak, have so far been spared, while illegal excavation of unexplored tombs in the ancient desert city of Palmyra had halted, Abdulkarim said.

    In some cases those illegal digs stopped simply because thieves failed to locate any treasures, as happened at the Bronze Age site at Ebla after they dug holes in an ancient courtyard at the royal palace.

    More than 4,000 items, including beads, coins, statues and mosaic panels, were turned over by Syrian customs last year to Abdulkarim's department, although nearly a third of those turned out to be counterfeit.

    The department is also working with UNESCO and Interpol to track down 18 mosaic panels smuggled to Lebanon.

    Combined losses so far remained just a modest fraction of Syria's priceless collection, Abdulkarim said, but added that protracted and escalating violence could usher in anarchy and more brazen theft.

    "So far the gangs and thieves are small scale operators and no organized international gangs have surfaced," he said. "But what could be terrifying is that column heads and columns and large stones could be stolen...and smuggled out of Syria."

    "If this happens, God forbid, then we are approaching the start of the tragic demolition of our past and future."

    New hope for saving Indian vultures at death's door

    Goran Ekstrom / RSPB

    A white-backed vulture, one of South Asia's most threatened birds. The scavengers provide a valuable carcass-disposal service in a region where sacred cows abound. The cattle's rotting corpses can be terrible health hazards.

    By Douglas Main
    LiveScience

    Vultures may not be the most pleasant birds to contemplate, given their motley appearance and association with death, but they serve a vital role in an ecosystem by eating dead flesh.

    Throughout India, vulture populations have plummeted to less than 1 percent of what they were a few decades ago, leading to an epidemic of uneaten cattle carcasses and spawning an increase in the number of rats, feral dogs and human rabies cases from dog bites.

    But there may be some hope for these much maligned birds: Their decline has slowed, stopped or even reversed in some areas of the Indian subcontinent, according to a paper published Thursday in the journal Science.

    The birds declined largely because ranchers started giving their cattle an anti-inflammatory drug called diclofenac that the birds ingested when they ate the dead cattle, said paper author and Cambridge researcher Andrew Balmford.

    In 2006, following revelations that diclofenac was deadly to the birds, the governments of India, Pakistan and Nepal banned the use of the drug for cattle. Bangladesh followed in 2010, and in May 2012 the four governments reached an "unprecedented political agreement" to prevent unintentional poisoning of vultures from veterinary drugs, Balmford said.

    Many ranchers have adopted an alternative drug that is safe to vultures, Balmford said, but the increase of other drugs is concerning, especially one that's close in structure to diclofenac, Balmford said. Restrictions on these drugs are needed, he added.

    Nevertheless, vulture numbers have leveled off in many areas, and increased elsewhere. In India, all three critically endangered species of vultures did not decline from 2007 to 2011, and one species — the oriental white-backed vulture — may have increased slightly, according to the paper.

    To help these large raptors rebound, conservationists have established vulture-safe zones. Within them are "vulture restaurants" that provide the birds with diclofenac-free carcasses  –  "which offer birdwatchers keen to track down vultures a chance to see them," Balmford said. There are also several successful captive breeding colonies, which act as backup populations until reintroducing birds into the wild becomes a possibility, he said. [How Do Vultures Find Dead Stuff?]

    "Conservation can work, even in extremely challenging circumstances — in this case an elusive and diffuse threat covering an entire subcontinent — provided there is political will, carefully targeted research and a willingness … to work together," Balmford said.

    Balmford elaborates on this theme in a recently published book titled "Wild Hope."

    Wild yaks are back — at least in the Tibetan Plateau

    Tony Lui / World Conservation Society

    Yaks take off running in a rugged northwestern area of the Tibetan Plateau.

    By Douglas Main
    Our Amazing Planet

    Yaks are coming back. At least they are in a remote reserve on the Tibetan Plateau.

    Researchers recently counted nearly 1,000 wild yaks in a rugged northern area of the plateau known as Hoh Xil, which is nearly the size of West Virginia and has very few human residents, according to the World Conservation Society, which helped conduct the census.

    Decimated by hunters in the middle of the 20th century, wild yaks are listed as "vulnerable" by the International Union for the Conservation of Nature, which is one step above "endangered." The animals once ranged in huge numbers throughout Tibet, Nepal, India and western China. Now the population across their entire range may be about 10,000, although the IUCN said this is only a rough estimate in the absence of solid numbers. The animal is protected in several areas throughout its range, such as in Hoh Xil.

    The yak is the third-largest beast in Asia, after the elephant and rhino, but due to its remote location has never been officially weighed. Yaks live in alpine tundra, grasslands and the cold desert regions of the northern Tibetan Plateau, ranging from 13,000 to 20,000 feet (4,000 to 6,100 meters) in elevation, according to the IUCN.

    "Wild yaks are icons for the remote, untamed, high-elevation roof of the world," researcher Joel Berger, who led the yak-counting expedition, said in a statement.  "While polar bears represent a sad disclaimer for a warming Arctic, the recent count of almost 1,000 wild yaks offers hope for the persistence of free-roaming large animals at the virtual limits of high-altitude wildlife."

    Berger and his team found more wild yaks near glaciers, which feed adjacent alpine meadows and provide food for the large beasts, the WCS noted. Less than 1 percent of the yaks varied in color from the rest, suggesting they aren't mixing and hybridizing with domestic yaks, as is often the case in more populated areas of Tibet, according to the release.

    Very little is known about wild yak biology, such as how often the animals breed and how many young yaks survive to adulthood.

    Of course they are running - you would take off running too if some maniac in a noisy helicopter were chasing you. It's good to see so many calves in the group - Ren & Stimpy will rejoice in the comeback of the Yak.
