STREAM FISH ECOLOGY AND CONSERVATION
MARK SCHORR, PH.D.
My research interest is in stream fish ecology. Stream conservation has been the major theme in my graduate research program. Most of my graduate students have studied the influence of watershed urbanization and/or riparian buffers on water quality, habitat features, and biotic health in Chattanooga area streams.
