Which Bat Is That? The Smell Will Tell

For the first time, people can distinguish one bat species from another by smell alone. Scientists from the USDA Forest Service and Arkansas State University found that a new, portable electronic nose (e-nose) device is capable of distinguishing between bat species by their smells. This study is part of a larger effort to help bats…  More 

Forests for Bats

“Almost all North American bats rely on forests for survival,” says Roger Perry, USDA Forest Service research wildlife biologist. Perry recently led the team that updated Forest Management and Bats, a booklet designed for private landowners and anyone managing forests. It was first published in 2006 by Bat Conservation International, and Daniel Taylor of BCI…  More 

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 

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 

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
