Frogs demonstrate adaptive changes in sexual signaling in response to urbanization

How do animals adapt to urban environments? In the case of the túngara frog, city males put on a more elaborate display than males in forested areas. By 2050, almost 70 percent of the world's population will live in urban environments, according to the United Nations. But as cities spread, wild animals will also have to adapt. Researchers working at the Smithsonian Tropical Research Institute report that male túngara frogs in Panama City put on sexier mating displays than frogs living in nearby tropical forests.
