Population recovery following decline in an endangered stream-breeding frog (Mixophyes fleayi) from subtropical Australia.

Amphibians have undergone dramatic declines and extinctions worldwide. Prominent among these have been the stream-breeding frogs in the rainforests of eastern Australia. The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) has been postulated as the primary cause of these declines. We co...
