Cyclic Occurrence of Fire and Its Role in Carbon Dynamics along an Edaphic Moisture Gradient in Longleaf Pine Ecosystems
Figure 3
Interactive effect of Windspeed*Site and PAR*Site on NEE.
Least square mean values of NEE at the xeric, intermediate and mesic sites over (a) a range of wind speeds, and (b) a range of PAR values. FCT 1 is the first 28 days following fire, FCT 2 and 3 are the next two 28 day periods, FCT 4 represents the next 140 days, and FCT 5 represents the next 224 days. To mitigate for autocorrelation PAR and NEE are 28 day means.
