Australia's top conservation biologist is on a mission to save hundreds of frog species from extinction. Dr Anthony Waddle has spent years studying the deadly chytrid fungus that has wiped out 90 species, but now he's working on a novel solution: mini saunas for frogs.
Waddle's journey began when he was just eight years old, catching tadpoles in the Mojave desert with his bare hands. The experience sparked a passion for amphibians that has driven him to become an award-winning conservation biologist. After completing his PhD from the University of Melbourne, Waddle is now working in Australia to develop frog-saving technologies.
One of his most innovative projects involves building mini saunas to warm up frogs during the winter months when the fungus is at its strongest. By raising the temperature, Waddle hopes to reduce the impact of the fungus and help stave off extinction. The first batch of saunas was built in a lab using masonry bricks and greenhouses over them, with eight little frog-sized holes for amphibians to curl up in.
Thanks to this experiment, frogs that spent their winters in these tiny greenhouses were much less likely to be infected by the fungus. The results suggest that synthetic biology could hold the key to saving many more species from extinction.
Waddle is now working on another project using gene replacement to support the reintegration of critically endangered southern corroboree frogs into the wild, a species that no longer breeds naturally due to disease and habitat loss. He believes his work may provide hope for turning around the dire plight of global amphibian populations.
In an interview from his lab, Waddle revealed that some might be concerned about synthetic biology's potential risks, but he's confident in its ability to add diversity to struggling populations or give vulnerable species a fighting chance against disease.
