Fig. 5: The ‘fast-slow forest spectrum’ and soil fertility as potential drivers of aboveground biomass and biomass productivity.
From: Functional composition of the Amazonian tree flora and forests
a ‘Slow’ forests (positive value) have much higher above ground woody biomass (AWB) than ‘fast’ forests (negative values) b Absolute above ground woody productivity (AGWP) does not vary significantly with the ‘fast-slow forest spectrum’. c Biomass produced per biomass standing (= Relative AGWP [100*AGWP/AGB]) is highest in ‘fast’ forests (negative values for slow-fast forest spectrum). d Relative AGWP is positively correlated with predicted sum of bases16. Red lines indicate 95% confidence intervals. Biomass data from sources55,83,168. Colours: Red, terra firme Pebas formation; brown, terra firme Brazilian Shield; orange, terra firme Guiana Shield; yellow, white sand forest; purple, swamp forest; light blue, várzea.
