Limonium narbonense in bloom in the San Felice salt marsh in the Venice Lagoon. n the background is Matt Ross’ experiment with tensiometers and oxygen sensors testing oxygen concentrations and water content at different elevations and under different vegetation types. Behind that is the Dolomites! The project was part of a collaboration with the University of Padova and the WISeNet IGERT at Duke http://wisenet.pratt.duke.edu.
Dr. Herb Bormann (Duke PhD, Ecology, 1952) returns to the Bormann plot to observe oak and hickory regeneration failure more than 50 years after his studies. March 2006 with Acer rubrum fully in bloom. For more on ecology and statistics of the forest-change data of the Bormann plot and the Duke Forest at large, see: (1) Bormann, F.H. 1953.
