Searching for a Solution to White-Nose Syndrome

bats

In the five years since the fungal disease white-nose syndrome was discovered in New York, the disease has spread to more than 190 sites in 16 eastern states and two four Canadian provinces. At one Canadian site alone, 5,000 bats died.

In this week's ScienceNews, the bats -- and the scientists working to study the disease -- are the subject of the cover article. 

Named for its devastating impact, the fungus,  Geomyces destructans latches onto living bats in the dead of winter. The fungus takes root during the winter hibernation period for bats such as the little brown bat, which suffers a 90 percent mortality rate from the fungus. At one New York location, the number of bats hibernating there went from 200,000 to only 2,000 in just three years. 

Scientists aren't just documenting the disease's spread and its potential devastation to ecosystems. They are also looking for antifungal solutions to halt the spread of the disease or help the bats resist it.

Bat Visitors Offer Insect Opportunity

batsWe occasionally noticed a bat flying around our lab space but didn’t pay too much attention to it. On our last night however, when it was unseasonably cold, several bats decided to use our lab as shelter. Often when the door opened one would fly in and around and then perch underneath one of our lab benches; five in fact were roosting together there at one point. I didn’t think too much of it until I recalled that bats have some pretty bizarre fly parasites that wander about through their fur. Suddenly this became an opportunity to make a novel entomological find. So eventually we got one in a butterfly net, and, while Choru held it down, I picked off the small flies with forceps. We let the bat go outside, but I suspect it may have flown right back in again.
