The Bats and the Bees

ROSENDALE, N.Y. — Bats in New York and Vermont are mysteriously dying off by the thousands, often with a white ring of fungus around their noses, and scientists in hazmat suits are crawling into dank caves to find out why.

"White nose syndrome," as the killer has been dubbed, is spreading at an alarming rate, with researchers calling it the gravest threat in memory to bats in the U.S.

"This is definitely unprecedented," said Lori Pruitt, an endangered-species biologist with the U.S. Fish and Wildlife Service in Bloomington, Ind. "The hugest concern at this point is that we do not know what it is."

White nose syndrome has afflicted at least four species of hibernating bats, spreading from a cluster of four caves near Albany last winter to more than a dozen caverns up to 130 miles away.

Alan Hicks, a wildlife biologist with the New York Department of Environmental Conservation, said he fears a catastrophic collapse of the region's bat population and is urgently enlisting experts around the country to find the cause.

It is not even clear if the fungus around the bats' noses — something scientists say they have never seen before — is a cause or a symptom. It may be a sign the bats are too sick to groom themselves, said Beth Buckles, a veterinary pathologist at Cornell University.

The die-offs could be caused by bacteria or a virus. Or the bats could be reacting to some toxin or other environmental factor.

Whatever it is, afflicted bats are burning through their winter stores of fat before hibernation ends in the spring, and appear to be starving.

The Northeast has generally had mild winters in recent years. But Hicks said he doubts that is the culprit in some way, since there are no reports of large die-offs in warmer states.

Nor are there any known links between what is wiping out the bees and what is killing the bats. The cause of the bee deaths is still a mystery, though scientists are looking at pesticides, parasites and a virus not previously seen in the U.S.
