>>If you’re a fan of frogs, then unfortunately you’ve probably heard of Batrachochytrium dendrobatidis (Bd). More commonly known as chytrid fungus, it’s been decimating amphibian populations around the world.
Bd causes a disease known as chytridiomycosis, which attacks the skin of frogs, toads and salamanders. As a result, the animals lose control of their ability to regulate their water and electrolyte levels, ultimately leading to heart failure. The geographic origins of the fungus have remained a mystery, limiting attempts to stop it at its source.<<
The above has decimated many frog populations throughout the world including Australia.
