Spartina-alterniflora root dynamics in a Virginia Marsh [link]Paper  abstract   bibtex   
A litter bag technique was used to measure root and rhizome decomposition and production f or 2 years in creekside and interior sediments in a Spartina alterniflora marsh on the seaside of the Delmarva Peninsula, Virginia, USA. Decay was equally rapid regardless of incubation in either creekside or interior sediments and did not vary with depth. Weight loss during the first growing season was 39 and 35 % (creekside and interior respectively). By the end of the second growing season between 81 and 88 % (creekside and interior respectively) of the starting root and rhizome material had decayed. In creekside sediments, very little root growth was measured during either year and root production was highly variable between years (1253 and 99 g m-2). In the interior marsh, the patterns of root growth and the amount of root material produced were similar each year (2016 and 2269 g M-2) . Root and rhizome turnover was faster in the creekside sediments (2.63 yr-1) than in the marsh interior (0.54 yr-1). The greater root production and slower root turnover in the interior marsh occurred in sediments with elevated salinities and oxidation- reduction potentials, and lower sediment saturation. These results suggest that differences in organic matter accumulation in high and low marsh areas may be explained by differences in root production and not differences in decay processes.
