Frogs don’t like living near noisy highways any better than people do, but research from Vanderbilt suggests that frogs, like hardened city-dwellers, can learn to adapt to the constant din of rumbling trucks, rolling tires and honking horns. And, just like those urbanites who can’t get a good night’s sleep without the sporadic sounds of sirens, some frogs have grown accustomed to the rattle and hum of the highway.
“The broad interpretation is that frogs adapted to noise are better able to cope with noise,” said Vanderbilt professor Louise Rollins-Smith, PhD, who conducted the research in collaboration with Penn State and three other institutions. “It suggests that these populations that are exposed to noise from the time of road building, which is 1940s, 1960s onward, have actually kind of evolved to accept these kinds of noise conditions.”
Published in Proceedings of the Royal Society B, the study suggests that traffic noise is harmful to frogs, yet frogs can adapt.
