  1. Picky Tongues A study of the eating habits of anuran species by Zach Moning, Leo Sack, and Willis Okech

  2. Background Information • The Order Anura includes frogs and toads • Frogs spend their entire lives in or around bodies of water, while toads return to water only to lay eggs • The species we study are all frogs

  3. Blanchard’s Cricket Frogs (Acris crepitans blanchardi)

  4. Northern Green Frogs(Rana clamitans melanota)

  5. Leopard Frogs(Rana pipiens)

  6. Research Question and Hypotheses • How does species size affect the eating habits of anurans? • We believe that larger frogs will have more diverse diets • We also believe that larger frogs will grow in biomass more rapidly than smaller ones

  7. Methods • Every other day, we offer each of the 15 frogs the following: crickets, guppies, meal worms, and worms • During each feeding time, we note which items have been consumed • Every week, we weigh the frogs

  8. What’s New, Pussycat…er, Frog? • Several Blanchard’s Cricket Frogs, on an apparent hunger strike, have perished (May they rest eternally in peace). Our specimen number has dwindled to 14 • One of the aquaria has sprung a leak, leaving us resorting to desperate measures • Our data collection has finally begun! w00t!

  9. Relevance of Research • Amphibians are the perfect bio-indicator • Anurans can become hella invasive, yo • American Bullfrogs in the American Midwest • Cane Toads in Australia • Several species of frogs and toads are disappearing, such as Blanchard’s Cricket Frogs • Your mom probably likes frogs

  10. What to do Today! • Aquarium cleaning (YAY!!!) • Taking data/Feeding frogs (YAY!!!) • Attempting to fix the broken aquarium (YAY!!!) • Weighing frogs (YAY!!!)

  11. “Frogs are Neat!”- Charles Darwin (probably) The end.
