Fewer Leaves Led to Frogs' Decline

Scientists working in Costa Rica have come to a startling conclusion as to the decline of the frogs' species in the region after studying 35+ years' worth of data: fewer leaves on the ground seem to be the cause.

A fungal infection was previously assumed to be the culprit, but scientists noticed that lizards who were immune to the infection were also in decline. Amphibians have declined by up to 75% since 1970 and scientists insist there is no human cause-effect relationship, such as the destruction of their habitat by encroaching civilization. This percentage in decline directly correlated with the decline in leaf litter on the ground, which provides the creatures with both food and shelter.

The new suspect?

Global warming.
