“…In this paper, the sediment moisture in tidal flat demonstrated LM > MM > HM (Table 1) and higher decomposition rates generally occurred in LM (high salinity and moisture) ( Table 2), indicating that the water regime in LM might be proper, which, to some extent, promoted the decomposition of the three halophytes. Similar result was reported by Haraguchi et al (2002) who found that the cellulose decomposition rate in Masukata mire (central Japan) showed significant positive correlation with the oxygen consumption rate. Tidal inundation was also an important factor influencing litter decomposition in tidal flat of the Yellow River estuary.…”

“…At present, many studies on the litter decomposition process in wetland ecosystems have been reported, and the research objects have related to freshwater marsh (Vargo et al 1998;Villar et al 2001;Anderson and Smith 2002;Welsch and Yavitt 2003;Xie et al 2004), salt marsh (Mendelssohn et al 1999;Bouchard and Lefeuvre 2000;Pereira et al 2007), mangrove swamp (Holmboe et al 2001;Dick and Osunkoya 2000;Tam et al 1998;Nielsen and Andersen 2003) and peat bog (Haraguchi et al 2002(Haraguchi et al , 2003Freeman et al 2004;Laiho et al 2004). Overall, the current research not only relates to the litter decomposition characteristics, the changes of organic matter composition and element [such as nitrogen (N), phosphorus (P), potassium(K), sulphur(S)] contents in litter in the decomposition process, but also focuses on the responses of litter decomposition to global changes (Cotrufo et al 1998;Dilustro et al 2002;Sowerby et al 2005).…”

From May 2005 to September 2006, the potential effects of marsh flooding regimes on the decomposition and nutrient (N, P) dynamics of Calamagrostis angustifolia litter were studied in the typical waterlogged depression in the Sanjiang Plain, Northeast China. The decomposition of C. angustifolia litter was related to four sites with different hydrologic regimes [F1 (perennial flooding, average water depth of 480 days was 40.14 ± 8.93 cm), F2 (perennial flooding 33.27 ± 6.67 cm), F3 (perennial flooding 23.23 ± 5.65 cm) and F4 (seasonal flooding 1.02 ± 1.09 cm)]. Results showed that flooding regimes had important effects on the litter decomposition, the decomposition rates differed among the four sites, in the order of F3 (0.001820d, and the values in the perennial flooding regimes were much higher. Flooding regimes also had significant effects on the N and P dynamics of litter in decomposition process. If the perennial flooding regimes were formed in C. angustifolia wetland due to the changes of precipitation in the future, the litter mass loss would increase 23.28-48.88%, the decomposition rate would increase 13.41-98.47%, and the t 0.95 would decrease 1.07 yr-4.50 yr. In the perennial flooding regimes, the net N accumulated in some periods, while the net P released at all times. This study also indicated that the changes of N and P content in the litter of the four flooding regimes were probably related to the C/N or C/P ratios in the litter and the N or P availability in the decomposition environment. If the nutrient status of the decomposition environment did not change greatly, the decomposition rates depended on the substrate quality indices of the litter. Conversely, if the nutrient status changed greatly, the decomposition rates might depend on the supply status of nutrient in the decomposition environment.
