A biologist who built mini saunas for frogs has big plans to save hundreds of species. Standing ankle-deep in water between two bare cottonwood trees on a hot spring day, eight-year-old Anthony Waddle was absorbed by an attempt to net tadpoles swimming in a reservoir in the vast Mojave desert.
For him, it was "one of the perfect moments in my childhood", fascinated by the attempt to catch as many tadpoles as possible and admire them. Tadpoles, he says, are so cool because metamorphosis is one reason why kids bring them home to watch that change.
Years later, Waddle has gone from a child obsessed with animal trivia to becoming an award-winning conservation biologist on a mission to save frogs from the deadly chytrid fungus. The experiment worked – frogs that spent winters warmer in their new shelters were less likely to fall prey to the infectious fungal pathogen, which is temperature sensitive.
He's now working on raising and vaccinating hundreds of green and golden bell frogs for release into the wild. Not all species can be vaccinated, however. For those that can't, he's experimenting with gene replacement to help support their reintegration.
Synthetic biology, a discipline in which organisms are edited by introducing or deleting genetic material, is innovative but also controversial. Waddle believes it could help add diversity to populations stuck in genetic bottlenecks and make vulnerable species disease resistant.
The challenges of conservation keep him awake at night – not due to dread, but anticipation of possible solutions. He often finds himself thinking about new experiments he wants to conduct in the middle of the night, grinning as he says "usually if I can't sleep, it's something exciting".
