“…The eutrophic and relatively dry conditions give rise to the development of highly productive, species-poor vegetation dominated by Phragmites australis at sampling location 0 and to a high abundance of Betula pubescens at sampling location 1. In the ''open mire zone'', permanent inundation of the mire surface (Table 2) facilitates the presence of sedges and Menyanthes trifoliata and prevents the establishment of trees and shrubs, as the latter require (at least periodically) water levels below the surface (Moore and Bellamy 1974;Wassen et al 1992). The high water levels can be ascribed to a large groundwater flux combined with a gentle slope of the mire surface and obstruction of surficial mire water flow by the peat ridges, which run parallel to the Ob River between locations 5 and 6.…”

“…This in turn largely determines the floristic composition and diversity of the vegetation of the mire (Kulczyń ski 1949; Sjö rs 1950; Moore and Bellamy 1974;Succow and Joosten 2001). Mires in river valleys exhibit distinct vegetation zones, both parallel and perpendicular to the river axis (Ratcliffe 1977;Pałczyń ski 1984), which have been shown to reflect different ratios in the supplies of groundwater, surface (river) water and precipitation (Oświt 1968;Wassen et al 1992Wassen et al , 2002bWassen and Joosten 1996). As in the temperate zones of Europe and European Russia, North America and Eastern Asia (China, Japan), these mires have largely been drained for agriculture (Joosten and Clarke 2002), and few studies have addressed the relations between water flow, water chemistry and vegetation in pristine river valley mires (cf.…”

“…Such a descriptive study contributes to our understanding of the eco-hydrological functioning of mires, which in turn is highly relevant for the conservation or restoration of these systems. Because a comparison with other mires might reveal general patterns, we compare our findings in the Ob mire with the characteristics of the well-studied, anthropogenically little affected mires in the Biebrza River valley in Poland (Wassen et al 1992;Wassen and Joosten 1996). Similarities and differences are discussed, and hypotheses are formulated for the differences observed.…”

Relations between vegetation characteristics and eco-hydrological processes were assessed in a pristine mire in the valley of the Ob River (Western Siberia). Along a transect from the terrace scarp to the river, field data were collected on vegetation composition, peat stratigraphy, peat chemistry, hydrology and hydrochemistry. Based on floristic composition, eight vegetation communities were distinguished. Hydraulic head measurements were used to obtain an indication of groundwater flow directions. The water balance of the mire was calculated with a two-dimensional steady-state numerical groundwater model. Water types were defined based on cluster analysis of hydrochemical data. The results revealed that the dominant hydrological factor in the Ob mire is the discharge of groundwater, which supplies about threefold more water than net precipitation. Although the discharge flux decreases with increasing distance from the terrace scarp, high water levels and a ''groundwater-like'' mire water composition were observed in the major part of the study site. Precipitation and river water play only a minor role. Despite dilution of discharging groundwater with rainwater, spatial differences in pH and solute concentrations of the surficial mire water are small and not reflected in the vegetation composition. Although small amounts of silt and clay were found in the peat in the proximity of the river, indicating the occurrence of river floods in former times, no river-flood zone could be recognized based on hydrochemical characteristics or vegetation composition. A comparison of the Ob mire with well-studied and near-natural mires in the Biebrza River valley (Poland) revealed substantial differences in both vegetation characteristics and the intensity and spatial pattern of eco-hydrological processes. Differences in the 123Plant Ecol (2007) 193:131-145 DOI 10.1007 origin and ratios of water fluxes as well as a dissimilar land use history would seem to be key factors explaining the differences observed.

In order to evaluate the impact of reclaimed water on the ecology of bacterial communities in the Typha angustifolia L. rhizosphere soil, bacterial community structure was investigated using a combination of terminal restriction fragment length polymorphism and 16S rRNA gene clone library. The results revealed significant spatial variation of bacterial communities along the river from upstream and downstream. For example, a higher relative abundance of γ-Proteobacteria, Firmicutes, Chloroflexi and a lower proportion of β-Proteobacteria and ε-Proteobacteria was detected at the downstream site compared to the upstream site. Additionally, with an increase of the reclaimed water interference intensity, the rhizosphere bacterial community showed a decrease in taxon richness, evenness and diversity. The relative abundance of bacteria closely related to the resistant of heavy-metal was markedly increased, while the bacteria related for carbon/nitrogen/phosphorus/sulfur cycling wasn't strikingly changed. Besides that, the pathogenic bacteria markedly increased in the downstream rhizosphere soil since reclaimed water supplement, while the possible plant growth-promoting rhizobacteria obviously reduced in the downstream sediment.Together these data suggest cause and effect between reclaimed water input into the wetland, shift in bacterial communities through habitat change, and alteration of capacity for biogeochemical cycling of contaminants.

Detailed modelling of the hydrological setting of fen meadows appears to be possible provided that detailed information on geomorphology, hydrochemistry and piezometric heads is available for a number of years. In the Laegieskamp, a small wetland reserve located in the central part of The Netherlands, a piezometric monitoring network was sampled for water quality analysis and piezometric heads between 1986 and 1992. Average yearly discharge and recharge periods were used for FLOWNET calculations. First, the models were used to determine, with the help of information on water quality, the hydrological systems in the study area. Secondly, they were used to de®ne the present and past hydrological setting of a fen meadow in the reserve. The hydrological systems and water quality in the study area have changed considerably over the past 65 years. At present the fen meadow is mainly fed by precipitation. The mineral-rich conditions favouring the fen meadow vegetation are thought to be maintained thanks to a clayey peat layer and an oscillating shallow water body that prevents rapid leaching of minerals. The sulphate content in the fen exhibits a pattern of temporal variation, which is related to the severity of the annual drought. Our study showed that groundwater¯ow is mainly lateral, instead of the assumed vertical in®ltration of groundwater in previous regional studies. This led us to the conclusion that conservation and restoration perspectives are much better than previously expected. The polluted middle, deep groundwater is not a major threat to this fen at the moment.
