Frogs use calls to find mates with matching chromosomes, University of Missouri researchers find
Date:12/27/2011

Columbia, MO When it comes to love songs, female tree frogs are pretty picky. According to a new study from the University of Missouri, certain female tree frogs may be remarkably attuned to the songs of mates who share the same number of chromosomes as they do. The discovery offers insight into how new frog species may have evolved.

Carl Gerhardt, Curators Professor of Biological Sciences in the MU College of Arts and Science and doctoral student Mitch Tucker studied two closely related species of grey tree frogs that live in Missouri, the eastern grey tree frog (Hyla versicolor) and the Cope's grey tree frog (H. chrysoscelis).

"To the naked eye human and frog the two frogs look exactly alike," Gerhardt said. "The frogs differ only in the number of chromosomes. The eastern grey tree frog has double the number of chromosomes."

To the ears of potential mates, the two species differ in their vocal performances.

"The males are both singing the same love song just one frog is singing it slower. It's kind of like the difference between Eric Clapton's original and unplugged versions of Layla," Tucker said.

In previous studies, the scientists found that tree frogs with more sets of chromosome have larger cell sizes, which slows down the trill rate. What was not known was whether the calling preferences of females are similarly linked to chromosome number.

To answer this question, Tucker simulated the chromosome duplication event by replicating spring temperatures early in the frog development. Females were grown to maturity and then exposed to computer-generated, synthetic male calls that differed by trill rate. They found that the females hopped toward the calls with the trill rate of the males with matching chromosome numbers, which indicates female preference.

"This shows that chromosome number alone can control the behavior that keeps the species separate," Gerhardt said. "In turn, as chromosome num
