Olson, who works at the agency’s Pacific Northwest Research Station, and her colleagues have the daunting task of tracking the disease, known as the amphibian chytrid fungus. Unlike the clearly visible white-nose syndrome killing bats in the U.S., the frog fungus cannot be seen except with a microscope. That makes scientists’ jobs that much more difficult.
