Jonathan Kolby, a policy specialist with the US Fish and Wildlife Service and the director of the Honduras Amphibian Rescue & Conservation Center, studies the global spread of amphibian chytrid fungus (Batrachochytrium dendrobatidis). Chytrid is a waterborne pathogen that causes chytridiomycosis in amphibians, a skin infection that can lead to lethargy and death. Kolby was part of a team that conducted a global assessment of chytrid infection released in Science earlier this year. The researchers found that over the past 50 years, chytrid has had a role in the decline of at least 501 species of amphibians worldwide, which include 90 species thought to be extinct.

This video, co-produced by Kolby, describes recent findings about chytrid’s devastating effects.
