             abstract = "This article discusses seasonal and interannual variations of the 
                         evapotranspiration (ET) rates in Bananal Island floodplain, 
                         Brazil. Measurements included ET and sensible heat flux using the 
                         eddy covariance method, atmospheric forcings (net radiation, Rn, 
                         vapor pressure deficit, VPD, wind speed and air temperature), soil 
                         moisture profiles, groundwater level and flood height, taken from 
                         November 2003 to December 2006. For the hydrological years 
                         (October-September) of 2003/2004, 2004/2005 and 2005/2006, the 
                         accumulated precipitation was 1692, 1471, 1914 mm and the 
                         accumulated ET was 1361, 1318 and 1317 mm, respectively. Seasonal 
                         analyses indicated that ET decreased in the dry season (average 
                         3.7 mm day1), despite the simultaneous increase in Rn, air 
                         temperature and VPD. The increase of ET in the wet season and 
                         particularly in the flood period (average 4.1 mm day1) showed that 
                         the free water surface evaporation strongly influenced the energy 
                         exchange. Soil moisture, which was substantially depleted during 
                         the dry season, and adaptative vegetation mechanisms such as leaf 
                         senescence contributed to limit the dry season ET. Strong drainage 
                         within permeable sandy soils helped to explain the soil moisture 
                         depletion. These results suggest that the Bananal flooding area 
                         shows a different pattern in relation to the upland Amazon 
                         forests, being more similar to the savanna strictu senso areas in 
                         central Brazil. For example, seasonal ET variation was not in 
                         phase with Rn; the wet season ET was higher than the dry season 
                         ET; and the system stored only a tiny memory of the flooding 
                         period, being sensitive to extended drought periods.",
