However, many of the causes of amphibian declines are still poorly understood, and the topic is currently a subject of ongoing research. Modeling results found that the current extinction rate of amphibians could be 211 times greater than the background extinction rate. This estimate even goes up to 25,000–45,000 times if endangered species ...
