Studies have shown that the molecular tools can be helpful in their conservation efforts. In India, more than 80% of amphibians are endemic and most show a narrow range of distribution.

According to the Nature study, which evaluated more than 8,000 amphibian species worldwide, two out of every five amphibians are now threatened with extinction. Climate change is one of the main drivers. Habitat destruction and degradation from agriculture, infrastructure, and other industries are the most common threats to these animals.Serendipitously, Stanford Professor Walter Brown came to Silliman later on, taking Dr. Alcala under his wing as they worked on herpetological research, or the study of amphibians.

The State of Amphibians in the United States. Amphibian declines are an acknowledged biodiversity crisis. Scientists noticed that amphibians were getting harder to find 30 years ago but causes, and the extent of the problem, were unclear.
