Bat, Bee, Frog Deaths May Be Linked

Why has disease been killing off bats, bees and frogs? Shared factors may link the deaths.

THE GIST

Habitat loss, climate change and pesticide use may be putting bats, bees and frogs at greater risk for diseases.
Fungal diseases affecting bats and frogs eat through their skin, sometimes even replacing it.
Conservationists are trying to create safe, man-made habitats for the animals.

In recent years, diseases have ravaged through bat, honeybee and amphibian populations, and now animal experts suspect that shared factors may link the deaths, which are putting many species at risk for extinction.

The latest setback affects bats, given this week’s announcement that the deadly fungal disease known as white-nose syndrome has been confirmed in already endangered gray bats. The illness, caused by the fungus Geomyces destructans, has mortality rates reaching up to 100 percent at some sites.

Simultaneously, Colony Collapse Disorder continues to kill honeybees, while yet another fungus, Batrachochytrium dendrobatidis, has wiped out more than 200 frog species across the world.

“It appears that many species are under an immense amount of stress, allowing opportunistic diseases to take hold,” Rob Mies, executive director of the Organization for Bat Conservation, told Discovery News. “Life is far more complex, so a single cause is likely not the only explanation for the bat, bee and frog deaths. There could be five, six or more factors involved.”

May 2012. The U.S. Fish and Wildlife Service has confirmed the presence of white-nose syndrome in federally listed endangered gray bats (Myotis grisecens) in Hawkins and Montgomery counties in Tennessee. White-nose syndrome (WNS) has decimated bat populations across eastern North America, with mortality rates reaching up to 100 percent at some sites. First documented in New York in 2006, the disease has spread into 19 states and four Canadian provinces. Bats with WNS may exhibit unusual behaviour during cold winter months, including flying outside during the day and clustering near the entrances of caves and mines where they hibernate. Bats have been found sick and dying in unprecedented numbers near these hibernacula: here.

October 2012. New findings on white-nose syndrome (WNS) are bringing scientists closer to slowing the spread of this deadly bat disease, according to recent and ongoing studies by the U.S. Geological Survey: here.

The fungus that is known to cause a disease called white-nose syndrome in hibernating bats has recently been discovered for the first time in Mississippi: here.

A parasitic mite has helped a virus wipe out billions of honeybees throughout the globe, say scientists: here.
