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.
FRISCO — A bat-killing fungal disease that has wiped out millions of the winged mammals has spread west into Oklahoma, reinforcing concerns that bats across the country are at risk from white-nose syndrome.
Three tricolored bats in a cave in Delaware County tested positive for the fungus, according to Oklahoma wildife biologists. This early detection is likely a precursor to the appearance of the full-blown disease in two to three years, according to conservation biologists with the Center for Biological Diversity.

FRISCO — Bat-killing white-nose syndrome has spread into Iowa, state wildlife officials confirmed this week, announcing that the deadly fungal disease was found on three bats near a cave entrance in Des Moines County (two little brown bats and one northern long-eared) and on four little brown bats collected in Van Buren County this winter.
Biologists first detected the fungus that causes white-nose syndrome in an Iowa cave in 2011, but did not find afflicted bats until this winter. The latest report means that the disease is now present in more than half of the 50 states, concentrated in the eastern half of the country, and once again, conservation groups are sounding the alarm, charging that wildlife agencies aren’t doing enough to protect the flying mammals.

FRISCO —New research by the U.S. Geological Survey and the University of Wisconsin is helping biologists solve the puzzle of white-nose syndrome, the fungal disease that has devastated bat populations in the eastern U.S. The new study how the disease progresses from initial infection to death in bats during hibernation.
“This model is exciting for us, because we now have a framework for understanding how the disease functions within a bat,” said University of Wisconsin and USGS National Wildlife Health Center scientist Michelle Verant, the lead author of the study. “The mechanisms detailed in this model will be critical for properly timed and effective disease mitigation strategies.” Continue reading “Biologists trace physiological course of bat-killing disease”→
