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 toadsThe 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 eggsFrogs 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 frogsThe 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?How does species size affect the eating habits of anurans? We believe that larger frogs will have more diverse dietsWe believe that larger frogs will have more diverse diets We also believe that larger frogs will grow in biomass more rapidly than smaller onesWe 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 wormsEvery 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 consumedDuring each feeding time, we note which items have been consumed Every week, we weigh the frogsEvery 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 14Several Blanchard’s Cricket Frogs, on an apparent hunger strike, have perished (May they rest eternally in peace).
