In earlier greenhouse and field studies, we found that upper leaves of Phragmites australis (common reed) and Spartina alterniflora (cord grass) tended to have lower levels of metals than lower leaves. Since lower leaves are produced earlier in the season and are older than upper leaves, there are two possibilities: (1) leaves produced earlier in the season have more metals than those produced later...
Marsh vegetation plays an important role in trophic ecology of estuaries. Once broken down to detritus, it is an important food source for manyorganisms. In Atlantic Coast marshes, the reed Phragmites australis hasbeen invading many areas once dominated by smooth cordgrass, Spartina alterniflora. In this study we evaluated the growth of and trophictransfer of metals to estuarine invertebrates when...
