Invasive pythons have been invading South Florida’s swamps because the Seventies—and lately, the snakes have been spreading north. Within the course of, they’ve drastically decreased native mammal populations within the Everglades and elsewhere. However a brand new research is trigger for optimism.
The research, which was performed by the U.S. Geological Survey and different companions, seemed on the mortalities of 19 child pythons between Might 2021 and February 2022. The purpose of the analysis was to study extra concerning the life cycles of the invasive serpents—that are notoriously arduous to trace or monitor within the wild.
The scientists used implanted radio transmitters to maintain tabs on the snakes—then responded to the scene at any time when one of many transmitters gave off a mortality sign. Of the useless juvenile pythons, 5 had been killed by alligators, three by carnivorous mid-sized mammals, probably bobcats or Florida panthers, and three by cottonmouth snakes. Seven of the deaths had been unattributed. One python died from attempting to eat a hispid cotton rat that was 106 p.c heavier than itself.
The analysis unequivocally reveals that some native species are concentrating on juvenile pythons as a meals supply. This comes on the heels of a 2022 incident during which a bobcat raided a python nest. That incident was described because the first-ever proof of a local animal preying on python eggs. Scientists hope data gleaned from the current research—and others to return— can inform administration techniques going ahead.

“We’d like extra data and are persevering with to trace juvenile pythons in Southern Florida to know their ecology, significantly motion, habitat use, and survival,” biologist Mark Sandfoss informed USA At present. “Our position as scientists is to attempt to tip the scales within the route of the native species and establish the weaknesses of the invasive species that we are able to exploit for administration functions.”
