                         America across vegetation and moisture gradients is investigated. 
                         From the moist northwest (Manaus) to the relatively dry southeast 
                         (P´e de Gigante, state of Sao Paulo) simulated seasonal cycles of 
                         latent and sensible heat, and carbon \flux produced with 
                         the Simple Biosphere Model (SiB3) are confronted with 
                         observational data. In the northwest, abundant moisture is 
                         available, suggesting that the ecosystem is light-limited. In 
                         these wettest regions, Bowen ratio is consistently low, with 
                         little or no annual cycle. Carbon \flux shows little or no 
                         annual cycle as well; e\fflux and uptake are determined by 
                         high-frequency variability in light and moisture availability. 
                         Moving downgradient in annual precipitation amount, dry season 
                         length is more clearly de\fined. In these regions, a dry 
                         season sink of carbon is observed and simulated. This sink is the 
                         result of the combination of increased photosynthetic production 
                         due to higher light levels, and decreased respiratory 
                         e\fflux due to soil drying. The di\fferential 
                         response time of photosynthetic and respiratory processes produce 
                         observed annual cycles of net carbon \flux. In drier 
                         regions, moisture and carbon \fluxes are in-phase; there is 
                         carbon uptake during seasonal rains and e\fflux during the 
                         dry season. At the driest site, there is also a large annual cycle 
                         in latent and sensible heat \flux.",
