Bob Inger and Harold Voris study the frogs that live in Borneo's tropical rain forests. Here they follow changes in movements of individuals and breeding activity. Their studies provide important information for conservation, and will help to determine whether Borneo's frog populations are undergoing the decline seen in less diverse frog communities elsewhere in the world.

Bob Inger was born in St. Louis, Missouri, and studied at the University of Chicago. Harold Voris was born in Chicago, Illinois, and studied at Hanover College and the University of Chicago.
