The spread of fungal diseases among frogs worries scientists


17/06/2011

Rapidly spreading lethal disease of amphibians animals reached the place bordering Darien National Park in Panama - the last area in the entire Neotropical region, where there was no trace of the disease even as scientists said this week. The disease is associated with a noticeable decline in the population and the disappearance of frog species in all stranah.Infektsionnaya fungal disease called hitridiomikozom (chytridiomycosis), as scientists assume, kills his victims, clogging their skin, thus contributing to their strangulation. And that, at least in part has to do - along with climate change, destruction and pollution of the environment - the disappearance of 94,120 species of frogs that are considered extinct since 1980 goda.Eto factors struck amphibians in South America, western North America, Central America , eastern Australia, Dominica and Montserrat in the Caribbean. And now, it may face Darien National Park, which is located in eastern Panama and is considered part of the neotropical - tropical highlands Ameriki.Osnovyvayas on the study of the disease that has spread to El Cope in western Panama, the scientists say they have little time left to save the frogs in Darien. In the five months since the first case of the disease in El Cope disease destroyed 50 percent of frogs characteristic species for this area, and 80 percent of its total population of frogs. "We want to keep all kind of in Darien, but now it’s absolutely no time" - said in a statement Gretvik Brian (Brian Gratwicke), a biologist from the Smithsonian Institute of Biology and International Project Coordinator Protection and Conservation of amphibians in Paname.V 2007, Doug Woodhams (Doug Woodhams), a researcher at the Smithsonian Tropical Research Institute, tested 49 frogs living in the neighborhood bordering the Darien, and found that none of them had positive results on the analysis of the fungus. But when he tested the 93 frogs from the same area in January 2010, he found that 2 percent were infected with the disease. "Finding hitridiomikoza frogs in the neighborhood bordering the Darien happened much faster than anyone could have predicted," - said Woodhams. "Perseverance and spread extremely rapidly transmissible fungus disturbs us greatly." In an attempt to save some of the Darien frogs from extinction, scientists Design Protection and Conservation of amphibians in Panama have already succeeded in breeding three species in captivity and are going to save more than 20 species. "These animals, which we print in captivity, will give us some time for us to find a way to control the disease in the world of wildlife, as well as a way to temper the threat directly," - concluded Vudhems.Original: LiveScience Translation: M.
