A deadly fungus is killing hundreds of thousands of amphibians and putting the golden frog at risk of extinction. ...the golden frog was already in critical danger, however, the advance of the fungus outbreak makes matters worse to a point that this species is likely to become extinct, said STRI research associate Roberto Ibáñez to Reuters. According to popular beliefs in Panama, those that see the golden frogthat graces Panama's lottery tickets and tourism brochureswill be blessed with good luck. The mysterious mold threatening the frog is spreading quickly in Panama, according to a group of scientists including Karen Lips, STRI visiting scientist from Southern Illinois University, to be published anytime in the Proceedings of the National Academy of Sciences (Check Neal Smith's sendings). Many frogs use their skin as we use our lungs. If it gets blocked up, they die, explains Lips. A separate study published last month in Nature cited global warming as a probable cause for the proliferation of the fungus. "We don't have actual numbers on population size. Such figures are notoriously difficult to confirm," said Ibáñez. "But the fungus has the capacity to completely wipe out populations of any size, and if the fungus doesn't kill them, the areas where they can be found are being deforested and polluted or developed," he said. Researchers say the fungus, which causes the infectious disease chytridiomycosis that affects amphibians, arrived in Panama in 1993 and was detected in El Copé, near the Caribbean with many frogs, in October 2004. Within four months, it had wiped out 57 out of a total of 70 frog, toad and salamander species, including many golden frogs, in the area. It was one of the species we found dead and infected with the fungus at El Copé. As far as we know, every species at the site was probably infested with it and died," added Lips. The fungus exists in much of the world and the Panama study is the latest example of its potential to wipe out entire amphibian populations. Scientists do not know where the fungus came from, but it has been spreading through the Americas, Australia and Europe since 1970. Its first documented appearance was in South Africa in the 1930s, Lips said. "It's as if we came across a disease that regularly kills everyone in a city, but also dogs, cats, horses, whales, bats and so on. It's a very unusual pathogen, with an incredible impact." On the other hand, The Washington Times recently published the efforts by the Maryland Zoo, the first to breed Panamanian golden frogs in captivity. The only hope is for us to keep them going, said the zoo spokesman Kerry Graces. In a few years, we may actually go back to Panama to create a conservatory there. According to St. Louis Zoo, golden frogs could become extinct in five years. They survive by eating small insects and other invertebrates. Females lay their eggs in water, where they hatch, usually within 24 hours. Adults have a poisonous chemical in their skin that protects them from predators. Last year, the National Zoo in the District borrowed four males and four females from the Maryland Zoo. They laid a "clutch" of golden frog eggs, all of which hatched in just a few hours. The Maryland Zoo, as well as the Detroit Zoothat reported on February 6 the hatching of hundreds of Panamanian golden frog tadpolesare members of the Project Golden Frog, established in collaboration with STRI.
