Penn researcher helps identify 'superfast' muscles responsible for bat echolocation
Date:9/29/2011

ers also did an experiment in which bats hunted insects in a chamber wired with microphones in order to determine the theoretical maximum frequency for a buzz without overlapping echoes, which could confuse the bat.

"We determined the power the muscles can deliver, much like how you measure a car's performance," Denmark's Elemans said. "We were surprised to see that bats have the superfast muscle type and can power movements up to 190 times per second, but also that it is actually the muscles that limit the maximum call rate during the buzz."

"You can think of it like a car engine," Mead said. "It can be tuned to be efficient, or tuned to be powerful depending on what you want it to do. It turns out that bats trade off a lot of force to be able to get these rapid oscillations. In a way it's like an engine that's been tuned for extremely high RPM."

Mead and Elemans plan further study of superfast muscles from a molecular and genetic perspective.

"With more and more genomes being sequenced, including one species of bat, and one from a bird we've studied,' Mead said, "we have some powerful tools to start pick apart whether or not similar genes are involved in various important roles."
