Myotis lucifugus, also known as the little brown bat, was once the most common wild mammal in the United States. Since 2006, however, millions of little brown bats, as well as several other bat species, have fallen victim to a highly contagious fungal disease known as white-nose syndrome (WNS). Named for the distinctive white growth on the snouts of infected bats, WNS is caused by the fungus Pseudogymnoascus destructans, which has thrived in caves since it was introduced to North America under mysterious circumstances. WNS causes deterioration of bats' skin and connective tissue and has been linked to a variety of abnormal behaviors, such as disrupted hibernation. The prognosis for an infected bat is grim: WNS's mortality rate is more than ninety percent in some species. Some scientists have predicted that, if no cure is found, little brown bats may go extinct before 2030.
