Photo by Chris Hauer.<\/p><\/div>\n Emerging infectious diseases pose an increasing global threat to wildlife species in several taxa.\u00a0 Our lab has focused extensively on white-nose syndrome, a devastating disease of hibernating bats caused by an invasive fungal pathogen.\u00a0 This disease has killed millions of bats, reducing their beneficial roles in insect regulation, pest control, and the maintenance of rare cave communities.\u00a0 We are currently studying the impacts of white-nose syndrome on regional populations of bats, the ecological and behavioral responses of bats to the disease, and the identification of novel and effective means to manage the pathogen and protect wild bats from the worst effects of the disease.<\/p>\n Ecological restoration within working landscapes Prescribed fire for land management at Fort Indiantown Gap.
