About the Arkansas Unit

The Arkansas Unit is led by Brett DeGregorio -Wildlife - who oversees Unit operations. Dan Magoulick is the Assistant Unit Leader – Fisheries, and Diane Moler is the administrative assistant for Unit activities. David Krementz is the former unit leader and is an emeritus faculty member at the University of Arkansas.

Drs. DeGregorio, Krementz and Magoulick hold research faculty rank at the University of Arkansas, conduct research projects, mentor graduate students and teach graduate level courses. Research projects usually support graduate students and post-docs and address a variety of topics ranging from the invasive crayfish ecology in the Spring River to understanding waterfowl and freshwater turtle harvest in Arkansas. Research funds for the Arkansas Unit come from a variety of sources including AGFC, USFWS, USFS, and USGS.


The Fullbright College of Arts and Sciences at the University of Arkansas at Fayetteville is the home of the Arkansas Unit. Unit offices are currently located on the 5th floor of the Science and Engineering Building.
