The snakes are part of a study at the Savannah River Site that's testing the contention that pythons are capable of surviving in climates similar to their natural habitat, which includes much of the Southeast U.S.
Of the seven snakes released into the enclosure, many were reluctant to leave their traveling bins and remained coiled when ushered out. Although some snakes assumed a defensive position, the inactivity isn't unusual for Burmese pythons.
"These guys tend to sit around until something comes by to eat," said Michael E. Dorcas, the Davidson College associate professor of biology who's leading the study in conjunction with SREL researchers.
The study has come about because Burmese pythons, kept as pets for decades, have been introduced into a new habitat. The snakes - which can grow longer than 20 feet, live for 15-25 years and are native to Southeast Asia - were either released or escaped into the Florida Everglades where they are wreaking havoc in the foreign ecosystem.
"There are certainly thousands of them in the Everglades," said John D. Willson, of SREL, who is one of many technicians involved with the study working primarily as a volunteer. "They camouflage so well, we can't really determine how many there are."
There is concern over what the pythons would do if there were a mass migration north.
The year-long study, which is being filmed by National Geographic and will air early in 2010 on the National Geographic channel, will examine the ability of invasive Burmese pythons to survive in a semi-natural enclosure at a different temperature than the Everglades. The study will specifically monitor the survivorship, body condition, weight, behavior and thermal biology of the pythons.
"It's not going to be definitive but it will provide insight to determine if the climate models are accurate," Dorcas said of the study, which is being funded in a joint effort by SREL, Davidson, the University of Florida and the U.S. Geological Survey. "The information will be important in determining what course of action can be taken so they can't be established in South Carolina."
The snakes will be checked daily to ensure they are in the enclosure. It's for this reason that, when the first snake was released, someone cautiously cheered, "Be free ... Within the enclosure."
In the unlikely chance any python escapes, it can be tracked by tracing a radio transmitter that was surgically implanted into each snake Wednesday. The pythons are also identifiable by an ID tag that was also implanted during surgery and an ID number scrawled on it. Additionally, the technicians can identify the pythons by their distinctive patterns.
Aiken is an ideal location for the study since it fits the climate model in question. SRS is a logical site to conduct the study since it's the home of SREL, which already had a snake-proof enclosure.
"It provides opportunities found nowhere else in the world," said Dorcas.
