WNS Hits Mammoth Cave NP

MACA_long_cave_MYSE_4Jan2013_forReleaseMammoth Cave in Kentucky used to be one of the largest bat hibernaculums in the world. Indiana bats were particularly fond of the place, and the decline of the cave as a hibernaculum served as a warning to how vulnerable that species is.

On Wednesday, the National Park Service announced that white nose syndrome (WNS) had been confirmed in a northern long-eared bat in Long Cave, a cave in Mammoth Cave National Park that had been closed to visitors for more than 80 years.

“It grieves me to make this announcement,” said Mammoth Cave National Park Superintendent Sarah Craighead in a press release.

Mammoth Cave National Park is home to two federally endangered species of bats and one considered a species of special concern by the US Fish and Wildlife Service. It is also home to two state endangered bat species, two state threatened bat species and one species of special concern to the Kentucky State Nature Preserves Commission, according to the National Park Service.

WNS was first discovered in Kentucky in April 2011. The US Fish and Wildlife Service’s white nose syndrome map shows another detection in Kentucky this season, in Bell County, making these the first reports of WNS this season.

Belly Up to the Cobble Bar

Cobblestone tiger beetles are found in 11 states, plus New Brunswick, Canada. A study in New York State published in American Midland Naturalist found that while one beetle moved 322 meters from its original capture point, the rest were recaptured at points ranging from zero to 123 meters away. One male that was captured three times over 21 days was found at distances from six to 68 meters from his original point of capture.

A total of five beetles moved between cobble bars during the study. Sometimes the beetles traveled a distance farther than the next cobble bar. The study found cobblestone tiger beetles in cobble bars with greater interior areas and higher shrub covers than other cobble bars. The paper includes a habitat model.

The idea was to collect data for a management plan, and it could contribute to your own.
