Fluctuating water table affects gross ecosystem production and gross radiation use efficiency in a sedge-grass marsh
Original language description
The eddy covariance method was used for continuous measurement of the seasonal courses of the following parameters of the carbon cycle in a sedge-grass marsh type of wetland ecosystem, gross ecosystem production (GEP), net ecosystem production (NEP) andecosystem respiration. During a 3-year series of measurements, we recorded marked fluctuations of the water table, which affected the overall water regime of the wetland studied. Between-year differences in the water regime strongly influenced the totalannual carbon sequestration. The lowest annual GEP and NEP of 996 and 152 g m2 of carbon, respectively, were recorded in 2006, a year with two large floods, one in the spring, the other in the summer. By contrast, in the dry year of 2007, with no flood,the highest annual GEP and NEP were recorded: 1,328 and 274 g m2, respectively. Significant differences were found in the efficiency of solar energy use for GEP [gross radiation use efficiency, GRUE = GEP/PhAR (photosynthetically active r
