The fungal infection called chytridiomycosis has swept through the diversity-rich continent in little more than two decades, a new study finds.
in the journal Frontiers in Conservation Science. Ominous news from the study suggests that one lineage of the fungus assumed to be benign is more common and possibly more virulent than previously thought.
The devastation to amphibian species is wreaking havoc on ecosystems around the world. Frogs and salamanders feed on disease-causing mosquitoes and other insects, keeping their populations in check. They also provide food for larger frogs, snakes and some bird species.
The fungus kills by causing an amphibian’s skin to grow up to 40 times its normal thickness, making it hard for the animals to breathe and causing them to become dehydrated. Eventually, many get conditions that cause their hearts to stop. “I like to see studies like this that combine a lot of different methods to tell a story,” said Andrea J. Adams, assistant researcher at the Earth Research Institute at the University of California at Santa Barbara.
