Case Study: Evolution of Tungara Frog Mating Calls
In recent years, the scientific community has renewed its interest in establishing the relationship between the evolution of animal behavior and phylogenetic characteristics. Dr. Michael Ryan at the University of Texas, Austin, and Dr. A. Stanley Rand, staff scientist at the Smithsonian Tropical Research Institute, have dedicated years to developing a deeper understanding of the intricacies of Physalaemus frog recognition mechanisms, breeding behavior and how & why animal communication systems evolve.

In this case study, you will use some of the techniques Ryan and his colleagues have available in their labs to help characterize the evolutionary relationships of Physalaemus frogs, including
molecular information, acoustic parameters, and observed female frog response.
