Sniffing for pythons in the Everglades

Some bomb-sniffing dogs trained to fight terrorism are being taught to find a different nemesis — Burmese pythons  in Florida’s Everglades National Park.

The dogs are members of “EcoDogs,” a three-year-old collaboration at Alabama’s Auburn University between the science departments and the school’s Canine Detection Research Institute, which trains dogs to detect explosives.

Environmentalists fear the non-native pythons are upsetting the ecological balance of South Florida. Their spread is generally attributed to irresponsible pet owners dumping their snakes and 1992′s Hurricane Andrew, which destroyed an adjacent exotic snake warehouse.

Now they’ve adapted to the Everglades, and park officials say there’s no way of eradicating them. Instead, with help from dogs, they hope to keep them from further spreading.

In a trial run, the dogs showed they can cover a search area 2.5 times faster than a person.

“People can only see that the snake is there if they can see the snake. The dogs can smell the snake even if it’s not visually apparent to us,” said Christina Romagosa, a biologist at Auburn.

Two black Labrador retrievers from EcoDogs, Ivy and Jake, were sent to the 2,358-square-mile park in 2010 and demonstrated their skills to the U.S. Army Corps of Engineers, according to a Reuters report that appeared in the Chicago Tribune.

Todd Steury, an Auburn conservation biologist and co-founder of the project, said training a new dog to detect a scent takes six to 10 weeks. Training for each additional scent, he said, takes “about 10 minutes. You can do it by accident if you’re not careful.”

In controlled experiments, the EcoDogs success rate in finding pythons at the park was 75-92 percent, Romagosa said. The dogs helped researchers trap 19 pythons, including a pregnant snake with 19 eggs, according to an EcoDog report.

Are dogs the answer to lax airport security?

Could dogs have prevented Umar Farouk AbdulMutallab from boarding a plane with explosives hidden in his underwear?

CNN asked the question yesterday — the answer to which is, with enough properly trained dogs, probably.

But explosives-detecting dogs, the report points out, aren’t generally trained to sniff out humans, and having them do so might raise some privacy concerns.

Still, those quoted in the report say, something as low-tech as dogs could be our best solution to the problem.

“The fact that this individual showed up with a one-way ticket, purchased with cash and no checked baggage — he should have been pulled aside,” said security expert Larry Berg, a consultant with Berg Associates. “And at that point, if inspected by a dog, he literally could have been detected.”

“A well-trained dog and a very good, well-trained handler can find explosives with little or no false alarms,” said trainer Patrick Beltz said. “And if they had been doing it, it might have deterred him from trying to get on the plane in the first place.”

About 700 bomb-sniffing dogs currently work at U.S. airports, and they are trained to detect up to a dozen different explosive compounds, including PETN, the compound that AbdulMutallab is alleged to have smuggled aboard Northwest flight 253 to Detroit on December 25.

The report also looks at research underway at Auburn University in Alabama, where dogs are being used to sniff not people, but the air they leave in their wake when they pass by. The Auburn trainers believe their dogs can detect very small traces of explosives and then follow the trail to the person carrying a bomb.
