Figure 2

Average diel soil CO2 efflux plotted against average soil temperature for all biotic treatments within soil temperature treatments. Lights were turned on at 09:30 (represented by a triangle) and shut off at 21:30 (represented by a square). Arrows represent the clockwise hysteresis detected in all situations. Fsoil was estimated from 5 cm depth to the surface. Wet and dry conditions are computed together for each soil temperature treatment.
