Midwife toads that live in the mountains are highly likely to die from a serious fungal infection, called chytridiomycosis, whereas their infected relatives in the lowlands are not, according to new research published Jan. 24 in Ecology Letters. The authors of the study, from Imperial College London, the Zoological Society of London and the BiodivERsA project RACE, say their findings suggest conservationists may be able to limit the impact of the disease in the mountains by ensuring tourists...

Amphibians like frogs and toads have existed for 360 million years and survived when the dinosaurs didn't, but a new aquatic fungus is threatening to make many of them extinct, according to an article in the November issue of Microbiology Today. The fungus, Batrachochytrium dendrobatidis (Bd),was found to be associated with waves of amphibian extinctions in Central America and north-eastern Australia in the 1990's. Bd infects over 350 amphibian species by penetrating their skin, but little...

Most countries throughout the world participate in the $40-million-per-year culinary trade of frog legs in some way, with 75 percent of frog legs consumed in France, Belgium and the United States. Scientists at the Smithsonian Institution and colleagues have found that this trade is a potential carrier of pathogens deadly to amphibians. The team's findings are published in the scientific journal Frontiers in Ecology, Thursday, Nov. 19. Amphibians are rapidly declining worldwide. More than...

A workshop at the Smithsonian Tropical Research Institute in Panama has dramatically improved the ability of conservationists and regulatory agencies to monitor the spread of chytridiomycosis"”one of the deadliest frog diseases on Earth. Caused by the chytrid fungus, Batrachochytrium dendrobatidis, this disease is probably responsible for the extinction of nearly 100 frog species since the 1970s. During the past decade, the epidemic swept from the highlands of Costa Rica through western...

Sometimes to see something properly, you have to stand farther back. This is true of Chuck Close portraits where a patchwork of many small faces changes into one giant face as you back away. It may also be true of the frogs of Central America, where the pattern of extinctions emerges clearly only at a certain spatial scale. Everyone knows that frogs are in trouble and that some species have disappeared, but a recent analysis of Central American frog surveys shows the situation is worse than...

A U.S. study suggests amphibians might be able to develop immunity to the fatal fungus disease that is reducing the Earth's amphibian populations. Jonathan Richmond of the U.S. Geological Survey and colleagues said they discovered individual amphibians can develop both acquired and innate immunity to the fungal disease chytridiomycosis, which is caused by the fungus Batrachochytrium dendrobatidis. The researchers said scientists should broaden their studies of chytridiomycosis to include...

New evidence suggests that both acquired and innate immunity play a role in fighting off the fungal disease that is leading to dramatic declines in amphibian populations worldwide Amphibian populations are declining worldwide, principally because of the spread of the fungal disease chytridiomycosis. Researchers know that some amphibian populations and species are innately more susceptible to the disease than others. Recent preliminary evidence, described in the April issue of BioScience,...

The "mountain chicken frog" of the tiny Caribbean island of Montserrat is the latest victim of a lethal fungal disease that is devastating amphibian populations throughout the world. British researchers say that just two small pockets of mountain chicken frogs (Leptodactylus fallax) are all that remain disease-free on the entire island.  Conservationists are working to take the surviving frogs, some of the world's largest, into captive breeding programs. Experts believe the chytrid...

Scientists at the University of Idaho currently are involved in a CSI-like investigation of a killer known to have been running rampant for the past decade. But the killer's name can't be found on the FBI's Most Wanted list. Instead, it's on the minds of ecologists on every continent in the world. Its name is Batrachochytrium dendrobatidis (Bd). It is a "chytrid" fungus that lives on keratin, a type of protein found in the skin of amphibians, and is particularly deadly for certain species of...

Scientists from Manchester University and Chester Zoo have ventured into Costa Rica with hopes of finding some of the world's most endangered frogs. Their journey will take them deep into the forests of Monteverde where they will be on the lookout for the rare amphibians, including the golden toad, last seen about 20 years ago. "Costa Rica's highlands used to be major biodiversity hotspots - but in many areas, amphibian populations have been completely decimated," said team leader Andrew...
