Declining Frog Species (Image 2)

A Bob's robber frog (Craugastor punctariolus, in the family Craugastoridae). This picture was taken in 2002 near EI Cope, Panama, two years before the chytrid fungus outbreak. Today, the species not only may be extirpated from this location, but globally as well. Researchers are looking for populations of the species to find out its current status.

First noted when the golden toad and about half of the frog species disappeared in Monteverde reserve in Costa Rica in 1987, the killer fungus has been spreading eastward through the Central American highlands and also through a large portion of the Andes Mountains (likely from a separate introduction) ever since.

Researchers like Andrew J. Crawford, an associate professor in the department of biological sciences at the University of the Andes, Columbia, and a research associate at the Smithsonian Tropical Research Institute in Panama, are studying the decline in frog populations in parts of South America.

You can read more about the deadly chytrid fungus in the National Science Foundation press release "Frog Killer Caught in the Act." To learn more about Crawford's research and what you can do to help with frog species decline, visit his website Here.
