Extended Data Fig. 5: CO2 treatment effect for all ecosystem fluxes at EucFACE.
From: The fate of carbon in a mature forest under carbon dioxide enrichment
a, The CO2 response of gross ecosystem carbon uptake, including GPPo and GPPu, and soil methane uptake (CH4). b, The eCO2 response of annual incremental change in carbon pool (ΔCpool), including overstorey leaf (ΔCol), stem (ΔCstem), coarse root (ΔCcroot), fine root (ΔCfroot), intermediate root (ΔCiroot), understorey aboveground (ΔCua), leaf litter (ΔClit), soil (ΔCsoil), microbe (ΔCmicr), aboveground insect (ΔCins), and mycorrhizae (ΔCmyco). c, The eCO2 response of NPP, including overstorey leaf (NPPol), stem (NPPstem), coarse root (NPPcroot), fine root (NPPfroot), intermediate root (NPPiroot), understorey aboveground (NPPua), twigs, barks and seeds (NPPother), and leaf insect consumption (NPPins). d, The eCO2 response of ecosystem R and other outgoing fluxes, including respiration fluxes of overstorey leaf (Rol), stem (Rstem), root (Rroot), understorey aboveground (Rua), growth (Rgrow), insect (Rins), heterotroph (Rhetero), and soil (Rsoil), and volatile carbon emission (VC) and DOC leaching. Dots and grey bars represent means and standard deviations of the CO2 treatment difference, predicted by a linear mixed model with plot-specific pre-treatment LAI as a covariate. Red dots indicate negative means and blue dots indicate positive means. Dashed lines indicate change of scale along the x-axis.
