U.K. zoo builds a "love shack" for critically endangered frogs

What does it take to encourage endangered species to breed? In the case of two frog species living at Bristol Zoo Gardens in England it takes creating a very special environment, and not just one that plays romantic music.Bristol Zoo just finished building AmphiPod, a high-tech facility that "will allow us to adjust the temperature, humidity and day length to create the perfect conditions to encourage the frogs to breed," said Tim Skelton, the zoo's curator of reptiles, in a prepared statement.In addition to mimicking the frogs' natural habitat, AmphiPod will also help to protect them against disease, including the deadly chytrid fungus that is rapidly devastating frog populations around the world.The frogs taking up residence in the new "love shack" are the lemur leaf frog ( Hylomantis lemur ) from Panama and Costa Rica and Madagascar's golden mantella frog ( Mantella aurantiaca )...
