Bat populations in the western portion of the US are threatened by the rapid westward expansion of White-nose Syndrome (WNS), a disease implicated in the loss of over a million bats since 2006. Pseudogymnoascus destructans (Pd), the fungus believed responsible for WNS, has been confirmed in southeastern Wyoming, southcentral Kansas, western Oklahoma and the Texas panhandle, potentially placing at least 13 of the 18 bat species native to Colorado at...

"White-nose syndrome" (WNS) is an emerging fungal disease of hibernating North American bat species. To date, WNS has likely killed between 5.7 and 6.7 million hibernating bats in caves and inactive mines in the eastern USA, and has contributed to the imperilment of some bat populations and species. The WNS fungus (Geomyces destructans) has the potential to kill individuals of many of the 18 bat species native to Colorado. Bats are ecologically and...
