New study reveals link between population crash and leaf litter

A recent study published in the National Academy of Sciences reveals new evidence about the cause of declining amphibian populations in Centeral and South America. Scientists have been studying these regions for decades, pointing to such factors as fungal infections and human impact as a cause for declines. But recently, it was noted that reptiles have also suffered, though they are not susceptible to the same range of disease that amphibians carry. Scientists began to investigate areas where humans are not a factor, and discovered that leaf litter levels have also deceased as climate change alters the health of the forests that these animals inhabit.
