“…Due to this limitation, the peats have low organic sulfur contents (0.32 ± 0.09 wt % S) with δ 34 S values similar to the plants forming the peats and the surface waters in the swamp (18,19). Furthermore, in a study of moss and underlying peats from the Karkonosze Mountains in Southwestern Poland (20), the isotope signal from the moss was transferred to the underlying peat (within about 2 per mil), and in the peat bog "Nad Jagniecym Potokiem" in the Izerska Mountains in Southwest Poland, the δ 34 S of Sphagnum and Polytrichum mosses were consistently within 2-3 per mil of the surface water sulfate source (21). In a comprehensive study of Sphagnum moss from a variety of spruce forest floors in Europe, the δ 34 S of the plant sulfur resembled that of the source sulfate, but with a consistent 2 per mil shift to 34 S-depleted values during assimilation (22).…”

“…The mix of these variable sources will depend on the proximity of the peats to groundwater flow, to riverine input, and on the amounts of sulfate delivered by rain, all of which will change from peat to peat (e.g., refs. 20,25,31). In many modern peats, rainwater is often cited as a major source of sulfate to the plants forming the peat (e.g., refs.…”

Sulfate is the second most abundant anion (behind chloride) in modern seawater, and its cycling is intimately coupled to the cycling of organic matter and oxygen at the Earth's surface. For example, the reduction of sulfide by microbes oxidizes vast amounts of organic carbon and the subsequent reaction of sulfide with iron produces pyrite whose burial in sediments is an important oxygen source to the atmosphere. The concentrations of seawater sulfate and the operation of sulfur cycle have experienced dynamic changes through Earth's history, and our understanding of this history is based mainly on interpretations of the isotope record of seawater sulfates and sedimentary pyrites. The isotope record, however, does not give a complete picture of the ancient sulfur cycle. This is because, in standard isotope mass balance models, there are more variables than constraints. Typically, in interpretations of the isotope record and in the absence of better information, one assumes that the isotopic composition of the input sulfate to the oceans has remained constant through time. It is argued here that this assumption has a constraint over the last 390 Ma from the isotopic composition of sulfur in coal. Indeed, these compositions do not deviate substantially from the modern surface-water input to the oceans. When applied to mass balance models, these results support previous interpretations of sulfur cycle operation and counter recent suggestions that sulfate has been a minor player in sulfur cycling through the Phanerozoic Eon.

“…Broadly, these problems arise from differences in the isotopic composition of different organic macromolecules within Sphagnum, of different moss components, of different peat forming plants (mosses, vascular plants) as well as the admixture of rootlets of e.g. from dwarf shrubs together with differences in the isotopic offsets in time, in the mixing ratio between peat compartments and in decomposition rates (Ménot-Combes and Burns, 2001;Moschen et al, 2009;Skrzypek et al, 2010).…”

In this study, we present a record spanning the last 4000 years from a Baltic bog (Kusowskie Bagno) in northern Poland. Using numerous biotic and abiotic proxies, such as testate amoebae (depth to water table reconstructions), stable carbon isotopes ( 13 C), plant macrofossils (proxies for local vegetation and mire surface wetness), pollen and spores (proxies for regional vegetation and human impact), we reconstructed and identified the regional hydro-climatic signal of Kusowskie Bagno bog and compared it to other bog records around the Baltic Sea. Our aims were to: 1) combine the species traits of bryophytes and testate amoebae, and more common proxies (isotopes, plant micro-and macro-remains) to infer past peatland development, 2) compare the hydroclimatic signal of Kusowskie Bagno bog to existing records around the Baltic Sea. We found that Kusowskie Bagno bog was very wet during the last 4000 years, and even drainage and peat exploitation had not disturbed its hydrology in northern part in the last 200 years. Carbon isotopes and plant macrofossils were significantly related to specific traits of testate amoebae, which in turn reflected the water table changes over the last 4000 years. Kusowskie Bagno recorded at least the following wet shifts: AD 250, 550, 850, 1250 and 1700, while wet conditions occurred during the Migration period at ca AD 550. Furthermore, the testate amoeba-based quantitative wetness reconstruction in Kusowskie Bagno bog resembles the pattern observed in other sites around the Baltic, i.e., Estonia, Finland, Ireland, northern Britain and the 7500-year record from the Stążki bog, northern Poland. Our results provided statistically validated evidence that interactions between plant and microbe need to be more considered further to reconstruct past hydrological. This is the first study of past hydro-climatic changes in peatlands based upon a trait-based approach.

“…According to these authors this relation was probably caused by the direct uptake of sulphur compounds without preference for one of the isotopic forms (de Caritat et al, 1997). Skrzypek et al (2010) believes that mosses do not have the ability to restrict sulphur uptake. In these plants, sulphur concentration and stable sulphur isotope composition are kept at equilibrium with the concentration and stable sulphur isotope composition in the environment.…”

34 S enrichment (up to 4.7‰) in the mosses tested indicates that these plants responded to environmental pollution stress. Sulphur isotopic composition in the transplanted P. schreberi was related to S concentrations in this species after 90 days of the experiment. Higher δ34 S values and S concentrations were noted in native mosses than in those transplanted from rural and urban sites while an opposite situation was reported in industrial sites. The transplanted P. schreberi was a better sulphur bioindicator than the native moss in more polluted industrial sites and worse in less polluted rural and urban sites.
