Current Projects:

A young Eastern Pipistrelle, covered with dew, a "Dew Baby"

The effects of human impacts on the restoration of bat populations in Dunbar Cave State Natural Area
The project is determining near-neighbor spacing and site utilization by Eastern Pipistrelles (Pipistrellus subflavus) and other bat species in a severely impacted cave system, Dunbar Cave.  The research to date has focused on site fidelity of Pipistrelles in various chambers of the cave after the construction of a new "bat friendly" cave gate.  Project site

Determining the use of visual cues by Eastern Gray Squirrels (Sciurus carolinensis) in self or kin recognition
The project studied behaviors of Eastern Gray squirrels and the extent of use of visual cues used in identification of other individuals to identify kin during agonistic bouts.  Variation in aggressive behaviors of Sciurus carolinensis during feeding resulted in social behaviors similar to those described as self recognition or kin recognition.

Determining water quality impacts to Pleasant Grove Creek, Adairville, Logan County Kentucky
This project is funded by the Common Wealth of Kentucky's Nonpoint Source Program and the Environmental Protection Agency. With the cooperation of the APSU-GIS Center staff, the Center is developing a watershed plan for restoring the wetlands and stream riparian habitat. Online maps. Data portal.
