Description: This radio broadcast features an interview with a herpetologist who studies the native toads of the Sonoran Desert and an invasive species from the east, the American bull frog. The herpetologist, Dr. Cecil Schwalbe, describes the mating cycle of the native toads, which is connected to the yearly monsoon rains that wet the Sonoran Desert, as well as the impacts of the American bullfrog, a voracious predator with no natural enemies in the Sonoran ecosystem. He also points out that frogs and toads are regarded as sentinel species whose numbers are falling around the world. Users can hear recordings of toad calls and view a slide show of some of the toads. The broadcast is 8 minutes and 45 seconds in length.
