What’s killing the Bats
First it was bees. Now it is bats. Biologists in America are working hard to discover the cause of the mysterious deaths of tens of thousands of bats in the northeastern part of the country. Most of the bats affected are the common little brown bats(Myotislucifugus,) but other species, such as the long-eared bat, the small-footed bat, the eastern pipistrelle, and the Indiana bat have also been affected, In some caves, more than 90 percent of the bat populations have died.
One possibility is disease. A white fungus(真菌) known as fusarium has been found on the noses of both living and dead bats. However, scientists don’t know if the fungus is the primary cause of death, a secondary cause of death, or not a cause at all, but the result of some other conditions.
