A biologist who once spent hours catching tadpoles as a child has now dedicated his life to saving hundreds of species on the brink of extinction. Dr Anthony Waddle, 35, is an award-winning conservation biologist working in Australia to combat the deadly chytrid fungus that has wiped out 90 species and threatens over 500 more.
Frogs play a critical role in the ecosystem, consuming insects that transport human diseases, and their skin holds potential as a source of new painkillers. However, the fungus is almost always fatal, rapidly wiping out populations. Waddle's innovative approach involves building mini saunas for frogs to raise their body temperatures and stave off the disease.
The experiment was successful: frogs in warmer shelters were less likely to fall prey to the fungal pathogen, which is temperature-sensitive. They also showed resistance when re-exposed. This good news for some species but Waddle aims to develop scalable solutions to help many more at risk.
Synthetic biology, a discipline that involves editing organisms by introducing or deleting genetic material, holds promise. Waddle and his team are experimenting with gene replacement for critically endangered species like the southern corroboree frog, which no longer breeds in the wild. The goal is to test this method across multiple Australian species and potentially share it globally.
While challenges keep him up at night, Waddle remains optimistic, driven by anticipation of potential solutions rather than dread. His excitement often keeps him awake - thinking about experiments and ideas that could make a difference in conservation efforts.
