"Influence of summer flood on the net ecosystem exchange of CO2 in a temperate sedge-grass marsh" . . . "Characteristics of CO2\u2013C exchange were studied in a temperate herbaceous wetland in 2006 and 2007, years with contrasting hydrological regimes. Net ecosystem production (NEP) was calculated from the CO2 fluxes measured by the eddy-covariance technique and was compared with the seasonal course of plant live aboveground biomass. The results show that: (1) the annual net uptake of CO2\u2013C was 199 and 220 g C m1 yr1 in 2006 and 2007, respectively. The daily net CO2\u2013C uptake reached 12\u201320 g C m2 day1 in sunny summer days. (2) Although the observed wetland is adapted to floods, the summer flood substantially reduced its net CO2\u2013C uptake. The daily courses of net CO2\u2013C uptake point to reduced rates of CO2\u2013C fixation by the vegetation cover. (3) A recovery growth of plant biomass was associated with a second peak of NEP in September 2006. (4) Lack of knowledge on the dynamics of methane emissions presently limits deeper understanding of the effect of floods on carbon balance in wetlands." . .
