Florida Everglades Burmese Pythons are on Feeding Rampage

Two years back, scientists confirmed that as the python populace increased in the park, the quantity of small animals declined. At the same time they couldn’t demonstrate for sure that one caused the other.

Burmese pythons eat marsh rabbits in Everglades National Park quicker than any local predator, affirming what biologists have already suspected: the intrusive snake is changing the equalization of the park’s food chain.

A study distributed for the current week puts forth a stronger defense for the connection, taking into account the destinies of 26 rabbits fitted with GPS devices and let loose in the park in September 2012. The rabbits, which are local to the park yet have almost vanished in the most recent decade, did well. They settled in, began producing like bunnies and appeared to flourish, said University of Florida scientist Robert McCleery, one of the study’s authors.

At that point, as temperatures rised, the rabbits began to vanish. Where? Inside the python’s stomach.

Fed by the hot climate, pythons began eating up rabbits quicker than researchers expected — and significantly quicker than the rabbits could replicate.

“None of us would have predicted that 77 percent of the rabbits would be eaten by pythons,” McCleery said.

While McCleery is mindful so as not to say the outcomes demonstrate pythons are behind all other small animals’ decreases in the park, “We’d like to think we’re setting the stage to make it clear that this is a problem.”

Biologists picked the rabbits as an intermediary for all small mammals in light of the fact that they are for the most part flexible to predators, he said. Pythons likewise don’t confine their eating methodologies, so the rate of rabbit consumption could reflect different mammals.

After the 2012 discoveries, the discussion over the snakes’ effect on the park warmed up. A few researchers stressed the discoveries were excessively backhanded and recommended one of the numerous different dangers to the jeopardized environment, such as changing water levels, could be driving away small creatures.

“We saw a 90 to 95 percent decline in raccoons and possums,” said United States Geological Survey biologist Brian Falk. “That made people think, uh-oh, pythons are eating their way through the park.”
“We saw a 90 to 95 percent decrease in raccoons and possums,” said United States Geological Survey scientist Brian Falk. “That made individuals think, uh-gracious, pythons are eating some way or another through the recreation center.”

Working off the speculation of “what would happen if we could get rabbits and put them in Everglades National Park,” the researchers began catching marsh rabbits in stormwater-treatment regions outside the recreation center, strapping on trackers and discharging them inside the park. Like clockwork, the group searched for the rabbits to check their conditions. On the off chance that the rabbits quit moving for six hours, sensors cautioned researchers.

In 16 of the 17 rabbit passings, researchers discovered certain confirmation of the connections: trackers drove researchers specifically to snakes. The seventeenth rabbit had been spewed and was secured with DNA from a python, McCleery said.
