H.  aClimate seasonality limits leaf carbon assimilation and wood productivity in tropical forests.h[electronic resource]  c2016  aThe  seasonal  climate  drivers  of  the  carbon  cy- cle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combina- tion of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measure- ments and 35 litter productivity measurements), their asso- ciated canopy photosynthetic capacity (enhanced vegetation index,  EVI)  and  climate,  we  ask  how  carbon  assimilation and aboveground allocation are related to climate seasonal- ity in tropical forests and how they interact in the seasonal carbon cycle. We found that canopy photosynthetic capacity seasonality  responds  positively  to  precipitation  when  rain- fall is &lt 2000 mm yr-1 (water-limited forests) and to radia- tion otherwise (light-limited forests). On the other hand, in- dependent of climate limitations, wood productivity and lit- terfall are driven by seasonal variation in precipitation and evapotranspiration, respectively. Consequently, light-limited forests present an asynchronism between canopy photosyn- thetic capacity and wood productivity. First-order control by precipitation likely indicates a decrease in tropical forest pro- ductivity in a drier climate in water-limited forest, and in cur- rent light-limited forest with future rainfall &lt 2000 mm yr-1.  aCarbon sinks  aClimate change  aTropical forests  aWood  aCarbono  aFloresta tropical  aMadeira  aMudança Climática1 aHÉRAULT, B.1 aBONAL, D.1 aSTAHL, C.1 aANDERSON, L.
