Rescuing the Yellow-Legged Frog

The yellow legged frog is an endangered species that lives in the lake basins of the Sierra Nevada Mountains. Compared to the last 100 years, these frogs have seen a 96% decline in the past 10 years. At this rate, they are expected to become extinct within 5 years. At first, non-native trout introduced to the area were blamed for their disappearance, but it was soon discovered that a fungal disease called chytrid was the culprit. Recently, scientists discovered a symbiotic bacterium that counteracted this deadly fungus. It was tested on these frogs, but the results will not be known until the next generations of tadpoles are born in the spring. This is an example of the bleak future of amphibians, and human efforts to save them, although it may already be too late.
