WHY DO THESE TWO FROG SPECIES LOOK AND SOUND DIFFERENT?

We can do an experiment to find out!

(Teachers can email Dr. Ryan Taylor for the answer key at rctaylor@salisbury.edu)

For background information on these frogs and to hear their calls, see their species profiles here.

Female Mate Choice Experiments

The experiment setup:

​

We present the female with two speakers, each playing a different call. The females perceive the calls as coming from a male and approach the speaker that broadcasts the call she prefers. When the female approaches to within 5 cm of the speaker and stays within that vicinity for at least 3 seconds, we record this as her mate choice.
