Current Research

My research goals are to understand the biology and ecology of eastern forest bats to develop methods and guidelines for their conservation and recovery. Areas of current research include ecology of threatened and sensitive species such as the Indiana bat and Rafinesque's big-eared bat, effects of forest management practices on bat habitat use and community structure, and developing and testing methods to monitor bat populations across the landscape.

Research Interests

I am interested in the ecology, evolution, and conservation of mammalian species in natural systems and how these species adapt to anthropogenic changes. I am also interested in developing and testing new techniques for furthering our knowledge of mammalian species.

Past Research

My previous research addressed interactions between the southern flying squirrel (Glaucomys volans) and the endangered red-cockaded woodpecker (Picoides borealis). I also studied the importance of coarse woody debris and other forest structural characteristics on small mammals of southeastern forests.

Why This Research is Important

Bats are important components of healthy forest ecosystems and provide critical ecological services in forests, agroecosystems, and urban areas. Bat populations throughout the world have been declining for decades due to habitat disturbance, destruction and fragmentation. However, in recent years bat species have experienced even higher rates of mortality due to collisions with wind turbines and White-nose Syndrome, an emerging disease that has decimated bat populations throughout the eastern U.S. Further, some bat species will likely suffer negative effects due to climate change although other species may benefit from changing climates. Unfortunately, our knowledge and understanding of bat biology and ecology is not sufficient to allow managers to develop comprehensive conservation and recovery plans for most of these species.

Research Highlights

Riparian Zones (2010)
SRS-2010-016 In a recent study on the Nantahala National Forest in western North Carolina, Forest Service scientists investigated the importance of riparian zones to bats and salamanders, and tested the effects of riparian zone width on these important taxa.
Tracking the Decline of Bats in North America (2014)
SRS-2014-136 Though it's well known that bats in North America are declining rapidly from white-nose syndrome (WNS), wind energy development and other causes, the full extent of the decline has only been estimated. The North American Bat Monitoring Program (NABat) provides the statistical and logistical architecture for coordinated bat monitoring to support local, regional, and range-wide inferences about trends in bat distributions and abundances in response to WNS, climate change, wind energy development, and habitat loss. Results from this program will provide managers and policy makers with the information they need on bat population trends to effectively manage bat populations, detect early warning signs of population declines, and estimate extinction risk.
