Digging at study site (VIDEO) University of Florida This video is under embargo. Please login to access this video. Caption Lead author and recent University of Florida graduate Veronica Selden digs around a gopher tunnel so she can surround it with a 50-gallon drum. The drum prevents gopher interference long enough so Selden and co-author Jack Putz can measure how many roots grow back into the tunnel over time.
