The chytrid fungus devastating amphibian populations around the world has contributed to the presumed extinction of a Darwin's frog species, named after naturalist Charles Darwin. The fungus has also been implicated in the sharp decline of a second type of Darwin's frog. Both are in the genus Rhinoderma. The fungus blocks the absorption of vital nutrients, ultimately leading to death. Chytrid can be treated at an individual level, according to Marcus Rowcliffe of the Zoological Society of London. "That's not a large-scale solution ... but as part of a captive rearing program, it could be a very important part of the picture," he said.
