                         diffusive carbon dioxide flux (FCO2) from a hydroelectric 
                         reservoir located at Amazon rainforest. Our results showed that 
                         for the studied periods (2013 summer/wet and winter/dry seasons) 
                         the surface averaged FCO2 presented similar behaviors, with 
                         regular emissions peaks. The mean daily surface averaged FCO2 
                         showed no significant difference between the seasons (p > 0.01), 
                         with values around -1338 mg C m - 2 day - 1 (summer/wet) and -1395 
                         mg C m - 2 day - 1 (winter/dry). At diel scale, the FCO2 was large 
                         during the night and morning and low during the afternoon in both 
                         seasons. Regarding its spatial distribution, the FCO2 showed to be 
                         more heterogeneous during the summer/wet than during the 
                         winter/dry season. The highest FCO2 were observed at transition 
                         zone (-300 mg C m - 2 h - 1) during summer and at littoral zone 
                         (-55 mg C m - 2 h - 1) during the winter. The total CO2 emitted by 
                         the reservoir along 2013 year was estimated to be 1.1 Tg C year - 
                         1. By extrapolating our results we found that the total carbon 
                         emitted by all Amazonian reservoirs can be around 7 Tg C year - 1, 
                         which is 22% lower than the previous published estimate. This 
                         significant difference should not be neglected in the carbon 
                         inventories since the carbon emission is a key factor when 
                         comparing the environmental impacts of different sources of 
                         electricity generation and can influences decision makers in the 
                         selection of the more appropriate source of electricity and, in
