A deadly fungus, chytrid, is attacking frogs’ skin and wiping out hundreds of species worldwide. A chytrid infection prevents the normal movement of water and nutrients through the amphibians’s skin.
In the San Francisco Bay Area, Mountain yellow-legged frogs, found only in California’s alpine lakes, have been in steep decline due to the fungus (as well as predation by non-native trout). More than 90 percent of the population has disappeared.
Now in a last-ditch effort, scientists are trying something new: build defenses against the fungus through a kind of fungus “vaccine.”
