In more extreme cases, the frogs body becomes rigid, and its back legs trail behind it. One glimmer of hope in the devastation caused by these two fungi is there are frog and salamander species that do not develop the disease.

A National Geographic team has made the first ascent of the remote Mount Michael, looking for a lava lake in the volcanos crater. Bd remains a very serious threat, says Scheele, especially to unexposed amphibian populations, such as those in Papua New Guinea.

The news garnered headlines across the media, including National Geographic. But how big and how bad are questions that are critical to the conservation of frogs and salamander species that remain, argue the commenters.

As the fungus only affects keratinised tissue it does not cause the death of tadpoles they only have keratin in their mouthparts and so carry the disease until they metamorphose. The spores can also travel in wet mud in boots or on equipment. WebSigns of infection can be seen within 12-15 days following exposure.

Bd infects the keratin layer of the skin, where it multiplies by producing zoospores, which are shed into the environment. We use special filters to remove chytrid fungus and other harmful chemicals from the water we use. The striking decline in snakes is likely to have its own ecological effects, and hints at a much broader impact to the overall food web. A second related fungus, B. salamandrivorans or Bsal, primarily affects salamanders and was responsible for the decline of one species. Doing an analysis like this is challenging, but important, says Allan Pessier, a veterinary pathologist at Washington State University in Pullman who helped first identify Bd in amphibians.
