Bat Survival in Arkansas Mines

White-nose syndrome has been spreading through U.S. bat populations since 2006 and has caused mass die-offs in various regions of the country. The syndrome is caused by Pd (Pseudogymnoascus destructans), a fungus that invades the skin of bats while they hibernate. White-nose syndrome (WNS) symptoms include dehydration and irritation. These symptoms awake the bats frequently…  More 

Green Line Meeting in Arkansas Promotes Collaboration

On September 10, a Green Line meeting brought USDA Forest Service researchers and managers together, along with state partners. Participants represented the Southern Research Station, the Ouachita National Forest, the Ozark National Forest, and the Arkansas Forestry Commission. Twenty-eight people attended the meeting, including leadership from SRS, the Southern Region and Arkansas state forester Joe…  More 

Research for Mississippi and Beyond

Water defines the Mississippi Delta, an alluvial plain in northwest Mississippi. The Delta is sandwiched between the Yazoo and Mississippi Rivers, and a network of levees and pumps aim to keep the land dry enough for habitation and agriculture. In 2019, however, historic flooding left fields inundated for months. USDA Forest Service scientists have served…  More 

Can Southeastern Bats and Rock Climbers Share Cliffs?

“Researchers haven’t really studied cliffs as foraging areas for bats,” says USDA Forest Service scientist Susan Loeb. “When so little is known about that habitat, it can be hard to gauge the impacts of different uses or management plans.” Rapid growth in technical climbing has put rock climbers in the same spots as bats. How…  More 

Seminole Bats on the Move

Over the past 48 years, Seminole bats (Lasiurus seminolus) have drastically expanded their range. “The northern edge of their summer range has expanded by 323 miles,” says Roger Perry, a USDA Forest Service research wildlife biologist. “That’s approximately 7 miles a year since 1970.” The western range is also expanding, possibly because forests are replacing…  More 

E-Noses Detect Disease in Plants, Animals & Humans

The fragrance of a rose comes from volatile organic compounds. Living plants, animals, humans, and even inanimate objects emit complex mixtures of VOCs. VOC mixtures are so distinctive that new words are used to describe them: volatilome, breathprint, and smellprint. “There are over 2,000 VOCs in a person’s breath,” says USDA Forest Service scientist Dan…  More 

SRS Researcher Receives Grant to Study White-Nose Syndrome

White-nose syndrome (WNS) has killed more than six million bats over the past decade. WNS is caused by the fungus Pseudogymnoascus destructans (Pd). Studies show that bats eat enough insect pests to save the U.S. corn industry more than $1 billion a year in crop damage and pesticide costs, and more than $3 billion per…  More 

Story Maps: A New Approach to Communicating about Forests

The U.S. Forest Service Southern Research Station (SRS) Forest Inventory and Analysis (FIA) unit is increasing the interactivity and reach of forest science by using FIA and other data to create story maps on topics that range from southern forest products to white-nose syndrome. Developed on Esri’s ArcGIS Online platform, story maps are stand-alone web-based…  More 

Managing Forests to Conserve Bat Populations Affected by White-Nose Syndrome

In March 2016, scientists found bats infected with white-nose syndrome (WNS), a fungal disease that’s killed millions of North American bats across the eastern United States, in Washington state, over 1,000 miles from the nearest confirmed infection site in eastern Oklahoma. Because most bat species in the U.S. eat phenomenal numbers of insects, bats are important to agriculture and to forests and…  More 

Expanding the Reach of Forest Data and Research with Story Maps

The USDA Forest Service Southern Research Station (SRS) Forest Inventory and Analysis (FIA) unit is increasing the interactivity and reach of forest science by using FIA and other data to create storymaps on topics that range from southern forest products to white-nose syndrome. Developed on Esri’s ArcGIS Online platform, storymaps are stand-alone web-based resources that…  More
