A biologist has invented mini saunas for frogs to help combat a deadly fungus threatening hundreds of species. Anthony Waddle, an Australian conservation biologist, has developed a solution to save green and golden bell frogs from the chytrid fungus, which has wiped out 90 species and is threatening more than 500.
Waddle's experiment involves building frog-sized saunas in masonry bricks, which he hopes will help raise the body temperature of the frogs. By doing so, they would become less susceptible to the fungal pathogen, which thrives at cooler temperatures. The experiment was successful, with frogs that spent their winters warmer in their new shelters being less likely to fall prey to the fungus.
Waddle's next step is to develop a vaccination program for species that cannot be vaccinated using synthetic biology techniques. This involves raising and vaccinating hundreds of green and golden bell frogs, which will then be released into the wild to help boost their population.
While some experts have raised ethical concerns about synthetic biology in conservation, Waddle believes it can be a powerful tool in saving vulnerable species. "We can't just be willy-nilly slapping genes into frogs," he said, but at the research level, they should investigate synthetic biology as a solution to conservation problems.
The challenges of amphibian conservation are daunting, with over 40% of all species threatened with extinction. But Waddle remains optimistic about the potential of his work. "Usually if I can't sleep, it's something exciting," he said. "I'll be sitting in bed, thinking, 'Oh, we can do that experiment. We can do this experiment.'"
