Little Brown Myotis Persist Despite Exposure to White-Nose Syndrome

Abstract We monitored a maternity colony of little brown myotis Myotis lucifugus on Fort Drum Military Installation in northern New York in 2009 and 2010 for impacts associated with white-nose syndrome. Declines in colony numbers presumed to be caused by white-nose syndrome were initially discovered in the spring 2009. Although colony numbers have continued to decline, we determined that a minimum of 12 individual banded female little brown myotis survived over multiple years despite exposure to white-nose syndrome. Our results also provide evidence that 14 of 20 recaptured female little brown myotis were able to heal from wing damage and infection associated with white-nose syndrome within a given year, and seven of eight recaptures from within both 2009 and 2010 showed evidence of reproduction.
