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
