Local adaptation of Spartina alterniflora to environmental con-ditions may lead to dominance by different suites of genotypes in different locations within a marsh. Interestingly, although Spartina alterniflora marsh responded strongly to sea-level rise, we did not detect significant effects of increased atmospheric CO2 concentration (720 ppm). Salt marshes along the Atlantic coast of North America are frequently characterized by extensive stands of smooth cordgrass, Spartina alterniflora, distributed in two main phenotypes: (i) a tall form (>1 m) that grows near estuarine tidal creeks and (ii) a short form (<50 cm) that dominates the high marsh (Valiela, Teal and Deuser 1978; Mendelssohn and Morris 2000). Plant response to fungal root endophytes varies by host genotype in the foundation species Spartina alterniflora.

Data presented suggests that the short height form of Spartina alterniflora observed in inland areas of Louisiana Gulf Coast marshes is caused by toxic concentrations of sulfide, a result of slightly lower elevation and subsequently lower sediment redox potential than the adjacent productive streamside marsh. They are characterized by fine sediments and halophytic vegetation. Seedlings were spatially very patchy and tended to occur near clones that probably produced them. Official websites use .gov These results indicate that S. alterniflora populations developing on new substrata colonize broadly, but growth and reproduction vary with genotype and are influenced by changes in elevation (range: 11.8 cm), and probably other environmental factors, over relatively small distances.

The accretion rate and elevation change has been indicated as one of the most important factors in ecology of the marshes. One possible future scenario is that S. alterniflora may enhance accretion of the marsh such that the elevation rapidly rises, thereby eliminating these low elevation areas and shifting competitive dominance to S. alterniflora, much like that seen in natural elevation-dependent competitive processes between the lower S. mariqueter and the higher Scirpus tabernaemontani (Sun et al., 2003).
