abstract = "The carbon and water cycles for a southwestern Amazonian forest
site were investigated using the longest time series of fluxes of
CO2 and water vapor ever reported for this site. The period from
2004 to 2010 included two severe droughts (2005 and 2010) and a
flooding year (2009). The effects of such climate extremes were
detected in annual sums of fluxes as well as in other components
of the carbon and water cycles, such as gross primary production
and water use efficiency. Gap-filling and flux-partitioning were
applied in order to fill gaps due to missing data, and errors
analysis made it possible to infer the uncertainty on the carbon
balance. Overall, the site was found to have a net carbon uptake
of approximate to 5 t C ha(-1) year(-1), but the effects of the
drought of 2005 were still noticed in 2006, when the climate
disturbance caused the site to become a net source of carbon to
the atmosphere. Different regions of the Amazon forest might
respond differently to climate extremes due to differences in dry
season length, annual precipitation, species compositions, albedo
and soil type. Longer time series of fluxes measured over several
locations are required to better characterize the effects of
climate anomalies on the carbon and water balances for the whole
Amazon region. Such valuable datasets can also be used to
calibrate biogeochemical models and infer on future scenarios of
the Amazon forest carbon balance under the influence of climate
change.",
