By Paul RinconScience editor, BBC News website

Non-native Burmese pythons are the likely cause of a staggering mammal decline in Florida's Everglades.

In PNAS journal, they report that observations of some mammal species have declined by more than 99%.

Burmese python caught in the Everglades  USGSA team studied road surveys of mammals in the Everglades National Park before and after pythons became common.

Researchers found a strong link between the spread of pythons and drops in recorded sightings of racoons, rabbits, bobcats and other species.
