The first objective of this paper is to make the link between the
seasonality of fine root dynamics and soil respiration in a ponderosa pine (Pinus ponderosa P. & C. Lawson)
plantation located in the Sierra Nevada of California. The second objective is
to better understand how canopy photosynthesis influences fine root initiation,
growth and mortality in this ecosystem. We compared CO2 flux
measurements (NEE, soil CO2 efflux) with aboveground and belowground
root dynamics. Soil respiration was measured in a control and a trenched plot
to separate heterotrophic and autotrophic soil respiration.
