Abstract
Investigators need to know the calendar dates of the initiation and cessation of vegetative activity to schedule their fieldwork and, later, to simulate their field observations by means of synchronized computer models. The specific objective of our work in North Carolina is, first, to determine the length of the natural photosynthetic period in the eastern deciduous forest biome of North America, and then to correlate the observed spatial and temporal variation in its length with environ mental variation. This article reports some results of the descriptive and analytical phases of our project.
Contribution No. 89 from the Eastern Deciduous Forest Biome, US/IBP.
Research supported by the Deciduous Forest Biome Project, IBP, funded by the National Science Foundation under Interagency Agreement AG-100, 40-193-69 with the U.S. Atomic Energy Commission-Oak Ridge National Laboratory. Computer time was supplied by the University of North Carolina.
