“…The exponential breakdown rates of P. australis leaves at Lake Fertő/Neusiedler See evaluated by Dinka et al (2004) (k = −0.0030 and −0.0025 d −1 ) were similar to those found here, while the breakdown rates of P. australis culms (k = −0.005 d −1 ) were 3.5 times higher. This difference may be due to the differences in physical and chemical conditions of the sampling sites (Lake Fertő is a soda lake with a conductivity of 2000-4000 µS cm −1 , Lake Fehér is an alkaline lake with a conductivity of 489-657 µS cm −1 .…”

“…The nitrogen content in P. australis culms increased after its initial decrease; higher N content was observed here than in P. australis leaves and T. angustifolia litter because of the higher lignocellulose content of the culms (Dinka et al 2004). Increased nitrogen content in decaying plant material has also been observed in aquatic ecosystems (Kaushik & Hynes 1971;Polunin 1982;Hietz 1992;Suberkropp 1998;Casas & Gessner 1999).…”

The accumulation of nitrogen and phosphorus during the growing season can be attributed to the uptake of these elements from the surrounding water by microorganisms associated with the decomposing plant material (Gosselink & Kirby 1974;Mason & Bryant 1975;Davis & Van der Valk 1977;Webster & Benfield 1986;Mann 1988;Dinka & Szabó 2002;Dinka et al 2004). The decrease in the C:N ratio in the remaining litter ( Table 2) also shows that nitrogen was immobilized during the decomposition.…”

“…Probably the strong linkages between the hemicellulose and lignin found in P. australis culms are the reason why hemicellulose decomposed slower than the cellulose. Benner et al (1986) and Dinka et al (2004) also found that the polysaccharide components of Carex walteriana and of P. australis decomposed faster than lignin. Nutrients: Chemical differences in the initial quality of the litter types influenced the rate of decomposition.…”

Decomposition of air-dried live Typha angustifolia (L) stems and leaves and Phragmites australis (Cav. Trin ex Steud.) leaves and culms were studied in a shallow freshwater lake (Lake Fehér, Fertő-Hanság National Park, Hungary) using the litter bag technique. Samples were analyzed for dry mass, fiber (cellulose, hemicelluloses, lignin) and nutrient (C, N, P, S) contents, litter-associated fungal biomass (ergosterol concentration), potential microbial respiration (electron transport activity: ETS) and cellulolytic bacteria. In terms of mesh size, there were no significant differences in the examined parameters of P. australis leaves and culms and T. angustifolia stems with leaves. P. australis leaves had the highest rate of decomposition and P. australis culms the lowest. Hemicellulose degraded more rapidly than the other fibers, while the lignin had the slowest rate of decomposition. The ETS activity of the examined plant litter types increased from day 91 st to 237 th while decomposition processes were most active, ergosterol contents were high, and there were few cellulolytic bacteria. The counts of cellulolytic bacteria fluctuated during the decomposition period, they were high at the beginning then they decreased. In each case bacteria were found to be the first colonizers of plant detritus, and were followed by fungal growth.

“…Common Reed covers 54% of the lake, and 85% of the Hungarian part (75 km 2 ). P. australis, is the dominant species in the littoral zone and it has been shown to play an important role in the biogeochemical nutrient cycle of the lake through the uptake, storage and decomposition [27][28][29][30][31]. The lake has been declared a biosphere reserve by UNESCO, as well as a Ramsar wetland, National Park, and World Heritage site.…”

Reed stands may be employed in the amelioration of water quality or even in the treatment of wastewater. In this study, the nutrient concentrations of (i) the above- and below-ground Common Reed (Phragmites australis) biomass, and (ii) surface and interstitial water were analyzed in a natural stand used in wastewater treatment. The reed stand was located in Hungarian part of Lake Fertő/Neusiedler See, by the shore near Fertőrákos Bay. The nitrate, phosphate and dissolved organic nitrogen concentrations of surface water were found to be higher on the inlet side of the reed stand compared to the outlet. The N and P concentrations in the above-ground biomass and P concentrations in the below-ground biomass increased after the introduction of pre-treated wastewater. The inter-annual differences in the characteristics of sediment interstitial water and in the nutrient content of reed tissues were assessed using statistical methods. The samples taken before and after the introduction of the pre-treated wastewater in the parcel formed different clusters. The results of the study provide further evidence that the nutrient retention capacity of natural stands of P. australis may be employed in the treatment of wastewater while protecting and preserving the valuable natural assets of the lake.

Following the overall withdrawal of papermaking enterprises, Triarrhena lutarioriparia, a most abundant macrophyte of Dongting Lake wetland, will remain to be uncut and decay in the lake water. The decomposition dynamics of T. lutarioriparia tissues and the decomposition effects on water quality are investigated in this study. The results show that two main processes are observed during the 90-day decomposition period of T. lutarioriparia: rapid leaching and gradual biodegradation. During the initial 10-day leaching process, the initial weight loss of leaves, spikes, and stems reached 13.33%, 12.44%, and 4.67%, respectively; meanwhile, 15.12-32.62% of total nitrogen and 24.16-45.45% of total phosphorus in the tissues are released to the water. The decomposition rate of T. lutarioriparia tissues is in the order: spikes (0.0053 day −1 ) > leaves (0.0045 day −1 ) > stems (0.0033 day −1 ). The T. lutarioriparia decomposition exerted adverse effects on the lake water quality, including the depletion of dissolved oxygen, the increase in concentrations of organic matter and nutrients, especially during the rapid leaching process. Such adverse effects are significantly associated with both the biomass (p < 0.001) and the species of T. lutarioriparia tissues (p < 0.05).
