- Abstract:
- Anaerobic microorganisms produce CH4 and CO2 with a range of delta 13C values in soils of freshwater wetlands. Understanding microbial processes in such systems is important because stable isotope signatures provide an effective means to detect global changes in greenhouse gas sources and sinks resulting from climate change or human activities. Delta 13C values will be measured for soil CH4 and CO2 from a range of wetland types located in southwest England and Wales. Vegetation, porewater chemistry, water table levels, soil temperature and CH4 flux will be characterised at each site. Peat from cores will be incubated with 14C-labelled substrates at in situ soil temperatures to determine the subsurface distribution of methanogenic pathways. New insights will be gained into conditions that favour specific anaerobic microbial pathways which in turn control the delta 13C values of CH4 and CO2.
