A fungal pathogen that has wiped out bat populations across the eastern third of the U.S. has now been found in Texas, according to state wildlife officials, who documented the fungus for the first time on two new bat species: the cave myotis and a western subspecies of Townsend’s big-eared bat.
White-nose fungus first emerged in 2006 in New York and his since spread into 30 states and killed at least 5.5 million bats. Wildlife conservation advocates said the recent announcement from is a biological disaster, considering the potential risks to huge, world-famous bat colonies that thrive in unique cave ecosystems in the state.

Small hibernating bat colonies need protection to prevent extinction
Between collisions with wind turbines and deadly white-nose syndrome, endangered Indiana bats may not have much of a chance of recovering, according to a recently published U.S. Geological Survey study.
Are humans responsible for the big jump to the West Coast?
Genetic analysis shows that the bat-killing fungus recently detected for the first time in western North America is similar to strains found in the eastern United States. That means there is a good chance that humans were involved in spreading the disease, according to conservation advocates who want resource managers to step up efforts to halt the spread of the fungus by restricting cave tourism.
The new study, published in the journal mSphere, has implications for resource managers battling the spread of a disease that has wiped out millions of bats in North America. It provides new clues about the origin of this strain of the Pseudogymnoascus destructans fungus, or Pd. The latest case of WNS near North Bend, Washington was about 1,300 miles from the previous westernmost detection in Nebraska.

Conservation groups say agency sold out to special interests
Federal biologists say they won’t designate critical habitat for a species of bat threatened by white-nose syndrome. The decision was immediately protested by conservation advocates, who claim the U.S. Fish and Wildlife Service caved to industry pressure in making the decision.
In a press release, the USFWS explained that designating critical habitat wouldn’t be prudent, because it might increase the risk of vandalism and disturbance to bats at hibernation sites and could hasten the spread of white-nose syndrome. The decision doesn’t affect the bat’s threatened status under the Endangered Species Act.
Nebraska officials confirm presence of white-nose syndrome
Bat-killing white-nose syndrome has been confirmed in Nebraska, which means the deadly fungus has now spread to 26 states and five Canadian provinces, wiping out populations of hibernating bats along the way.
“While the presence of the fungus is disappointing, it is not surprising,” said Mike Fritz, a zoologist with the Nebraska Game and Parks Commission. “With the fungus being present in states around us and the migratory nature of bats, it was probably only a matter of time before it was documented in Nebraska.” Continue reading “Bat-killing fungus has spread across 26 states”→
LINZ — Even as they grapple with the devastating decline of bat populations caused by white-nose syndrome, researchers are starting to take a look at how, if and when some bats might recover from the fungal disease that has decimated colonies across the eastern U.S.
Standardized monitoring to help assess population trends
FRISCO — U.S. Forest Service scientists hope a new report will help scientists across the country track bats more effectively in an era when the flying mammals are facing unprecedented threats, including habitat loss and fragmentation, white-nose syndrome , wind energy development, and climate change.
Better tracking can help resource managers get the information they need to manage bat populations effectively, by detecting early warning signs of population declines, and estimating extinction risks.
