Urban frogs croaks different than frogs in the forest

the Study, published in Monday's edition of Nature Ecology & Evolution, has looked closely at the little froskearten tungara in Panama. The conclusion is that they are not croaks in the same way as american oksefrosk.

The panamanian froskens sounds heard with the human ear, more like a high-pitched sound of the kind one might hear in video games. But hunnfrosker hear it more as sengeprat.

Urban froskers paringsrop is faster, repeated more often, and is more detailed, compared with froskers paringsrop in the rainforest in Panama.

The more fancy the love song from the urban frogs are more effective – byfrosker are three times as likely to attract a hunnfrosk, called it in the study.

In the rainforest need hannfrosken to take two considerations: To attract a partner, and to safeguard its own security. In the city there are no froskespisende bats. It is also far less likely that a frog encounters enemies, such as snakes, in a city, point out the authors behind the study.

– An urban hannfrosk are able to assume greater risk, " says lead author Wouter Halfwerk.
