Current Projects
 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.

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.
