In Panama City, tungara frogs live in diverse urban environments: from ditches and puddles in neighborhoods close to tropical forest to drains among downtown skyscrapers.In their first experiment, Halfwerk's team played recordings of male tungara frog calls in 22 urban and forest locations and recorded the number of approaching females, predators and parasites using remote, infrared-sensitive cameras.How do city frogs compare with forest frogs when they call to attract females?In their first experiment, Halfwerk’s team played recordings of male tungara frog calls in 22 urban and forest locations and recorded the number of approaching females, predators and parasites using remote, infrared-sensitive cameras.In Nature Ecology and Evolution, researchers working at the Smithsonian Tropical Research Institute (STRI) report that male tungara frogs in Panama City put on sexier mating displays than frogs living in nearby tropical forests.“Tungara frogs sound a bit like pinball machines,” said Wouter Halfwerk, assistant professor at Vrije University in Amsterdam and visiting scientist at STRI.So, the frogs do not add extra garas when they know that predators are present.
Three out of four females preferred urban male calls."To their simple tun sound, they can add extra elements like the sound, gara, to make complex calls: tun gara gara--hence their name.They are nothing to look at, but just like male peacocks have fancy tails to attract females, tungara frogs add extra sounds to their calls to lure females in." But female frogs are not the only ones paying attention to male tungaras' love songs.Funds for this study were provided by a Marie Curie grant, a Veni grant, the Ecology fund of the Royal Netherlands Academy of Arts and Sciences, STRI and the U. by contributing institutions or for the use of any information through the Eurek Alert system.If you know us from AL’s TGP links don’t worry we’re still here!
Finally, they asked how fast frogs adjust their calls.
