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

Some bats may only survive in remnant populations
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.
For at least one species, the outlook isn’t all that bright, according to U.S. Geological Survey scientists who took a close look at the once-common little brown bat. Continue reading

Ophidiomyces ophiodiicola, a fungus that is afflicting snakes across the Midwest and Eastern US, shares many traits with Pseudogymnoascus destructans, the fungus that causes white-nose syndrome in bats, researchers report.

Numerous species, including rattlesnakes, affected by emerging fungal disease
FRISCO — Biologists say they’re tracking an emerging new fungal disease afflicting snakes that’s “eerily similar” to the fungus that has wiped out millions of bats across the eastern U.S.
The snake and bat pathogens emerged in North America in the mid-2000s. Both are moving from east to west across the United States and into parts of Canada. Continue reading

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.
White-nose syndrome has killed millions of bats since it was first detected in 2006, and more than 1 million have been killed at wind energy facilities since 2000. Combined with intensified pressure from land-use changes, scientists say there’s a real need for a continent-wide standardized monitoring system. Continue reading

Are western bats at risk?
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.

UC Santa Cruz research suggests preventive treatment may be possible
FRISCO — While most of the news about bats and white-nose syndrome is not good, there’s a glimmer of hope for a preventive treatment, according to scientists at the University of California, Santa Cruz.
In recent lab experiments, researchers at the university identified bacteria found naturally on some bats that “strongly inhibited” the he growth of the white-nose syndrome fungus.
“We are analyzing data from tests on live bats now, and if the results are positive, the next step would be a small field trial,” said Joseph Hoyt, a UC Santa Cruz graduate student who led the study. Continue reading

Conservation advocates say more protection needed
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.
