Extended Data Fig. 6: Canopy nitrogen and stem biomass.
From: Remote spectral detection of biodiversity effects on forest biomass
Field-measured canopy nitrogen concentration was positively associated with spectrally predicted canopy nitrogen concentration in both (a) the fifth growing season and (d) the sixth growing season. Field-measured stem biomass was positively associated with both (b) field-measured canopy nitrogen concentration and (c) spectrally predicted canopy nitrogen concentration in the fifth growing season, and with both (e) field-measured canopy nitrogen concentration and (f) spectrally predicted canopy nitrogen concentration in the sixth growing season. Thick line represents the regression line (P < 0.001).
