Hell: Frozen Over

It's official: White-Nose Syndrome has been found in Tennessee-- photo by Marvin Moriarty/USFWS

Biologists are calling it the most devastating wildlife decline in the past century in North America. Since White-Nose Syndrome was discovered in a New York cave in 2006, an estimated 5.7 million hibernating bats have died in the USA.

The hallmark of the disease is a powdery white fungus on bat noses, ears and wings. The fungus seems to irritate their skin, and bats rouse from hibernation months early. They either fly out of their caves during the daytime, dehydrated and dying, or use up all their fat reserves and freeze to death where they hang.

Over the past three decades, European bat specialists have reported seeing a small number of bats with white noses. But European bats soon groom the fungus off, and appear healthy. Is it the same fungus, and if so, why do European bats survive it?

In this article for Deutsche Welle, I spoke to bat disease specialist, Gudrun Wibbelt, at the Leibniz Institute for Zoo and Wildlife Research in Berlin. Wibbelt is doing her best to find out.
