Urban taunts frogs are more sexy than those in the woods

The turf frogs, which usually live in tropical forests in part of Latin America, change their mating rituals when they are in an urban environment where men are also more attractive to females, according to a study.

Connected calls

In the latest issue of the Ecology of Nature and Evolution, a team from the Smithsonian Institute for Tropical Research (STRI) publishes its findings on the behavior of frog frogs living in ditches, ponds and drains of Panama City

Just as male peacocks use their complicated tails to attract females, túngara frogs do the same by adding extra sounds to their mating.

But they do not know that there are predators like bats or parasitic flies that use these love frog songs to find their food.

Recording cameras with remote control

To conduct their research, the team led by Wuther Polusurk, assistant professor at the University of Vary in Amsterdam, and a visiting scientist at STRI in Panama, is dependent on Smithson of the United States, reproducing calls of frog frogs in 22 urban areas and forestry.

Through cameras with remote control infrared sensors, they monitor and record the number of women approaching as well as predators and parasites.

In the city, fewer women respond to calls, suggesting that men living in an urban environment should try harder to attract them.

In the second experiment, researchers recorded 100 men and discovered that urban men made more complex and familiar calls than those in the woods.

To find out which male frogs are more attractive, in the third experiment they put 40 women to hear calls from urban and forest men, and three out of four prefer the first.

Finally, scientists found that when urban men moved to the forest, they immediately simplified their calls.

The same does not happen with the men in the woods in the city, as they do not make more complex calls right away.

"As we change our social relationships in the cities, animals change their relationships and behavior in the radically changed biological communities we create around the world," concluded Rachel Pei, a STRI scientist and co-author of the study. EFE
