Frogs worldwide are facing a devastating fungal disease called chytridiomycosis, which has already wiped out 90 species and caused declines in many others. Scientists have discovered a potential solution to help frogs fight off this deadly infection by providing them with warm “saunas” during the winter months.
The disease, caused by the fungus Batrachochytrium dendrobatidis, thrives in cold, wet climates and has been particularly lethal to amphibians in these regions. To combat this, researchers conducted a study focusing on the green and golden bell frog, a species that has been severely impacted by chytrid.
By offering the frogs controlled environments with temperatures around 85 degrees Fahrenheit, researchers found that the frogs were able to clear the infection and develop immunity to future exposure. The use of black-brick structures to create heat-trapping “saunas” was particularly effective in helping the frogs fight off the disease.
While this method showed promise for the green and golden bell frog, researchers caution that it may not be suitable for all frog species, especially those accustomed to colder climates. However, the study represents a significant shift in the field of frog conservation, which has been overshadowed by a sense of hopelessness in the face of chytrid.
Experts like Ana Longo, a disease ecologist and evolutionary biologist, believe that this simple yet innovative approach could pave the way for more bold ideas to combat the spread of the fungus. By changing the narrative from one of helplessness to one of proactive intervention, researchers are opening up new possibilities for protecting endangered frog species from chytridiomycosis.
