From: Response of CO2 fluxes and productivity to water availability in two contrasting ecosystems in northern Benin (West Africa)

Fig. 8

Seasonal courses of the parameters characterizing both ecosystems during the four periods: a the coefficient w describing the WUE sensitivity to VPD; b the average canopy conductance (g c ); c NEE at the light saturation, A max; d the quantum efficiency, α; and e the dark respiration, ER d . Savannah (dark discontinuous line) and forest (dark continuous line). The lack of data during period I was due to the selection criterion of NEE and E in the WUE calculation. Error bars are 95 % confidence intervals and very low for g c and w
