Study Reveals Environmental Factors in Australian Frog Declines from Fungal Disease

A study analyzing historical and recent frog records across Australia, including data from the FrogID project, examined how frog distributions changed following the introduction of the amphibian chytrid fungus (Batrachochytrium dendrobatidis). The research focused on 55 frog species from eastern Australia, finding that species most affected by the fungus disappeared from colder, drier areas with greater temperature variability and higher elevations. The study also revealed that impacted species experienced greater reductions in their environmental niche breadth than in their geographic range. These findings have conservation implications, suggesting that understanding environmental refuges could help protect vulnerable species from additional threats like climate change.
