Researchers find bats use curled leaves for sound amplification

(Phys.org) —A pair of researchers, one from Universidad de Costa Rica, the other North Dakota State University has found that a type of bat that hides from predators inside a curled leaf plants, gains acoustic advantages from doing so. In their paper published in the journal Proceedings of the Royal Society B: Biological Sciences, Gloriana Chaverri and Erin Gillam describe recording experiments they conducted with the types of plants the bats hide in and found that the plant served as both megaphone and ear horn.
