Whats wrong with our frogs?
  • Extensive internal problems
  • Missing or extra legs
  • Unusual bone and cartilage formations in spine
    and lower jaw

4
Whats wrong with our frogs?
  • Eye deformities
  • Reproductive deformities that result in sterility
  • Distended bladders due to nonfunctional digestive
    systems

5
What we wanted to find out...
  • Are the increasing number of frog birth defects a
    sign of the thinning of the ozone layer?
  • Specifically, can we duplicate these deformities
    by using an ultraviolet light to simulate
    over-exposure to the sun?

Xenopus Mating
  • Xenopi are sexually mature at 10 months to 1 year
  • Usually mate during a genetically programmed time
    of year
  • Human Chorionic Gonadotrophin treatments can be
    used to induce breeding at any time

Looking back...
  • We did not get opportunity to see the effects of
    UV radiation of embryonic frogs
  • We still learned from the experience
  • Biological materials are unpredictable
  • Redundancy and experimental flexibility are the
    key to success
