Final answer:
The article discusses the devastating effects of white-nose syndrome on the Indiana bat and others, caused by the fungus Geomyces destructans introduced from Europe.
Step-by-step explanation:
The article is primarily about the impact of white-nose syndrome on cave-hibernating bats, particularly the Indiana bat, in eastern North America. This fungal disease, caused by Geomyces destructans (also known as Pseudogymnoascus destructans), has been introduced from Europe and has led to widespread population declines and an increased risk of extinction for species that are already endangered. The manner of its introduction is theorized to be through contaminated clothing or equipment of recreational cavers.
