“…The estimates reported here assume an immediate return to normal, pre-SO 4 2Ϫ rates of CH 4 emission. However, peatlands are net sinks of sulfur, which undergoes reduction and oxidation over short and long timescales (hours and years), moving between pools of varying biological availability, resulting in a likely extension to the duration of its impact on CH 4 emission (24,36,37). In this respect, any extrapolation is likely to be underestimating the size and duration of the effect of sulfur on wetland methane fluxes.…”

“…Elevated inputs of soil-derived SO; from dust storms of the 1930s a time of severe drought, might explain these profiles. However, because the forms of organic S and the dynamics of their interconversions in peat are not well known (Casagrande et al 1977(Casagrande et al , 1980Wieder et al 1985Wieder et al , 1987Lowe & Bustin 1985;Lowe 1986;Wieder & Lang 1986), diagenesis cannot be ruled out as a possible cause of the subsurface maximum in S content.…”

“…as well as in freshwater wetlands , Urban et al 1989, and S transformations have been demonstrated in peats and wetland systems (Wieder et al 1987). Iron reduction may be important in organic matter decomposition in many surface waters and wetlands Phillips 1986a, Driscoll et al 1987), and seasonal Fe 3+ and SO42 reduction has been demonstrated in a beaver pond in the Adirondacks (Driscoll el al.…”
