GGRO 2022 Season Summary: Research

It is no surprise that, as a forty-year-old Community Science program, the GGRO’s scientific publications and presentations should be steeped in collaboration and partnership. It’s not readily apparent from the list below, but the research on this page alone includes collaborators from Colgate University, State University of New York, Syracuse, Hamilton College, Cornell University, University of Florida, University of Georgia, University of California – Davis, National Audubon Society, and the National Park Service. Thanks to all our reasearch partners, and particularly to Dr. Joshua Hull of UC Davis, and Dr. Chris Briggs of SUNY Syracuse, for their leadership.
