White-nose syndrome has been spreading through U.S. bat populations since 2006 and has caused mass die-offs in various regions of the country. The syndrome is caused by Pd (Pseudogymnoascus destructans), a fungus that invades the skin of bats while they hibernate. USDA Forest Service wildlife biologists Roger Perry and Phillip Jordan conducted a study to calculate the survival rates of tricolored bats (Perimyotis subflavus) in the Ouachita Mountains of west-central Arkansas. The research helps satisfy the need for robust estimates of population data amid the WNS outbreak. The scientists chose to study the tricolored bat because it is common across North America and has suffered substantial declines due to WNS. The research highlights the importance of maintaining and protecting small hibernation sites as they may be critical to the conservation of the tricolored bat species.
