Tasmanian Devils Decimated by Mystery Cancer

The team is working on the disease's chromosome structure and has just identified the karyotype. (Karyotypes are pictures of cellular chromosomes that are used to check for abnormalities.)

The researchers say they have also been able to develop tumor cells in the lab, enabling them to run tests without actual tumors.

A diagnostic test and, ultimately, a vaccine are the scientific team's main aims. But while the scientists race to learn more about the disease, the Tasmanian government is trying to stop the disease from spreading farther.

To stop infected animals from moving in, trapping lines are being set in the north of Tasmania, an area that so far appears to be disease free.

The government is also considering whether to list the species as threatened under Australia's threatened-species laws. Threatened status would give the devils protection from other perils, such as habitat destruction caused by water pollution or land development.

The move would also require the government to draw up a plan for recovery of the species. Such a plan would focus on managing the disease where it already exists and on preventing it from affecting more animals.

The disease "is having a very serious impact on the wild population, but at this stage we don't believe that the species is headed for extinction," Scott said.

"In the areas where it has been present but [where] there's only a low level population, it has had a major impact. One of the problems is that the devil is nocturnal, and many people never see it in the wild. So it's very difficult to pick up changes in the population.''

Insurance Colony

The devil's plight has touched mainland Australia, where wildlife sanctuaries and zoos are being contacted about the possibility of establishing reserve populations of Tasmanian devils.

Melbourne's Healesville Sanctuary has been charged with keeping records of their Tasmanian devils' lineages, to ensure genetic diversity.

Adam Battaglia, a keeper at Taronga Zoo in Sydney, is preparing to send one of the zoo's two male devils to Tasmania.

"One male has been recalled to Tasmania because his genes are so valuable,'' Battaglia explained.

"He is going down to be part of the breeding program, so he will be very busy. All resources are being pulled back to the region. A national breeding program will be put back together because of what's happening in Tasmania."

"This example just validates other breeding programs we have like the platypus. They are common but there is always the fear something might happen."

There are 150 devils in captivity on mainland Australia and Tasmania. Making sure the animals stay healthy is a priority for their keepers.

If the situation among wild Tasmanian devils grows worse, captive devils may be moved to the mainland. But Scott, the Tasmanian environment official, says the island dwellers will remain where they are for the time being until more is known about the disease.
