“…KCl-extractable Fe, was of minor importance, which is in agreement with other studies (Wieder, 1988;Henrot & Wieder, 1990;Tarutis et al, 1992). However, it was shown in an earlier study (Norrstrôm, unpublished results) that the concentration in H3 varied greatly between separate soil samples.…”

“…Henrot & Wieder (1990) found that the binding of Fe to peat organics was the predominant mechanism of Fe retention up to saturation of the organic binding sites. Tarutis et al (1992) demonstrated that oxidizable Fe (defined as Fe bound to organic matter and sulphides) increased in a nonlinear fashion with Soil water was water sampled with suction lysimeters in the peat layer. The ranges were from three or four samples for all parameters.…”

“…Studies on Fe in wetlands have mostly been restricted to ones influenced by acid coal mine drainage (AMD). Wieder & Lang (1986), Wieder (1988), Henrot & Wieder (1990) and Tarutis et al (1992) all tried to identify characteristics and properties optimal for a maximal retention of Fe. Studies in non-polluted wetlands have measured total and exchangeable Fe only from the botanical point of view (Maimer, 1962;Sonesson, 1970;Danman, 1978).…”

“…A high positive correlation between Fe +2 and OM indicates the importance of OM for retention of Fe +2 , which is consistent with other studies (Henrot & Wieder 1990;Tarutis et al 1992;Grybos et al 2007). In an investigation of Welsh wet meadow soils, the concentration of Fe 2+ and OM were positively correlated with acidity in the soil (Blackstock et al 1998).…”

Abstract:The mountain wetlands studied represent a unique habitat on the southern slopes of the Alborz mountain range, the second largest range in Iran. In comparison with other parts of this range the western section is ecologically and botanically unknown. Floristic and vegetation variation were assessed using diverse environmental variables along a broad altitudinal span (350 m to 3200 m a.s.l.). Using both statistical and ordination analyses floristic variation was assessed on three defined altitudinal belts which were delimited based on Alborz macro-climatic boundaries. The distribution of individual wetland plant species, of phytogeographic elements and of life-forms all differ among altitudinal belts. This result is also shown in both direct and indirect analyses of ordinations. The proportion of geophytes significantly increases with altitude and geophytes are very well represented in the upper altitudinal belt. The number of species of a narrow phytogeographical distribution (e.g. endemics) increases with altitude, soil pH and EC declined with altitude. The first axis of DCA ordination with passively projected environmental variables indicates that, organic matter and concentration of Fe 2+ are increased toward higher altitude. The second axis of ordination is related to both soil texture and slope inclination. The distribution of species in the CCA species plot is also close to the distribution of those in the DCA ordination. This study indicates that altitude and slope together with other dependent environmental variables (pH, EC, Ca 2+ and soil texture) are the main ecological factors controlling species distribution across the Western Alborz wetland sites.

“…Wetlands are a traditional method for oxidative precipitation of Fe from AMD, and are attractive because wetland vegetation enhances residence time and retains Fe(III) (hydr)oxides (Kirby et al, 1999;Johnson and Hallberg, 2005). However, due to the inherently high productivity of wetlands (with the subsequent degradation of organic matter), anoxic zones develop where Fe(II) oxidation is limited and the reduction of Fe(III) (hydr)oxides by anaerobic bacteria may lead to the re-release of Fe(II) (Tarutis et al, 1992;Vile and Wieder, 1993;Tarutis and Unz, 1995;Johnson and Hallberg, 2002). By designing AMD treatment systems that mimic the GB system, the O 2 -dependent limitations on Fe(II) oxidation may be alleviated.…”

Characterization of Fe(II) oxidizing bacterial activities and communities at two acidic Appalachian coalmine drainage-impacted sites

We characterized the microbiologically mediated oxidative precipitation of Fe(II) from coalminederived acidic mine drainage (AMD) along flow-paths at two sites in northern Pennsylvania. At the Gum Boot site, dissolved Fe(II) was efficiently removed from AMD whereas minimal Fe(II) removal occurred at the Fridays-2 site. Neither site received human intervention to treat the AMD. Culturable Fe(II) oxidizing bacteria were most abundant at sampling locations along the AMD flow path corresponding to greatest Fe(II) removal and where overlying water contained abundant dissolved O 2 . Rates of Fe(II) oxidation determined in laboratory-based sediment incubations were also greatest at these sampling locations. Ribosomal RNA intergenic spacer analysis and sequencing of partial 16S rRNA genes recovered from sediment bacterial communities revealed similarities among populations at points receiving regular inputs of Fe(II)-rich AMD and provided evidence for the presence of bacterial lineages capable of Fe(II) oxidation. A notable difference between bacterial communities at the two sites was the abundance of Chloroflexi-affiliated 16S rRNA gene sequences in clone libraries derived from the Gum Boot sediments. Our results suggest that inexpensive and reliable AMD treatment strategies can be implemented by mimicking the conditions present at the Gum Boot field site.
