Amphibians are among the most threatened vertebrates globally, facing multiple welfare and conservation crises.
Amphibian welfare in the wild is catastrophically affected by the chytridiomycosis fungal pandemic, which has caused extinctions and mass die-offs unprecedented in vertebrate history. Infected amphibians suffer from skin dysfunction that impairs their ability to breathe, regulate electrolytes, and move — a drawn-out death from metabolic failure. Habitat loss, pesticide contamination, and climate change create additional welfare stressors. Conservation breeding programs have saved some species from extinction while researchers develop bioaugmentation strategies using beneficial skin bacteria.
