                         productivity and growth in forest ecosystems is key to 
                         understanding how these ecosystems will respond to global 
                         anthropogenic change, yet the linkages among these components are 
                         rarely explored in detail. We provide the first comprehensive 
                         description of the productivity, respiration and carbon allocation 
                         of contrasting lowland Amazonian forests spanning gradients in 
                         seasonal water deficit and soil fertility. Using the largest data 
                         set assembled to date, ten sites in three countries all studied 
                         with a standardized methodology, we find that (i) gross primary 
                         productivity (GPP) has a simple relationship with seasonal water 
                         deficit, but that (ii) site-to-site variations in GPP have little 
                         power in explaining site-to-site spatial variations in net primary 
                         productivity (NPP) or growth because of concomitant changes in 
                         carbon use efficiency (CUE), and conversely, the woody growth rate 
                         of a tropical forest is a very poor proxy for its productivity. 
                         Moreover, (iii) spatial patterns of biomass are much more driven 
                         by patterns of residence times (i.e. tree mortality rates) than by 
                         spatial variation in productivity or tree growth. Current theory 
                         and models of tropical forest carbon cycling under projected 
                         scenarios of global atmospheric change can benefit from advancing 
                         beyond a focus on GPP. By improving our understanding of poorly 
                         understood processes such as CUE, NPP allocation and biomass 
                         turnover times, we can provide more complete and mechanistic 
                         approaches to linking climate and tropical forest carbon 
                         cycling.",
