An Extensive Study and Analysis of System Modeling and Interfacing of Vanadium Redox Flow Battery. Several means of control and eradication have been employed against Spartina alterniflora where it has become a pest.  It grows in a wide range of salinities, from about 5 psu to marine (32 psu), and has been described as the "single most important marsh plant species in the estuary" of Chesapeake Bay.

Zonation of Spartina patens and Spartina alterniflora in a New England salt marsh. In New England salt marshes the boundary between frequently flooded low marsh habitats and less frequently flooded high marsh habitats is characterized by striking plant zonation.

Spartina alterniflora – U.S. Forest Service; Quick Facts. Palaemon vulgaris 44: 389–410. These results support the hypothesis that S. alterniflora is restricted to low marsh habitats by competitive displacement. , In Willapa Bay of Washington state, Spartina alterniflora was probably an accidental introduction during oyster transplants during the nineteenth century and may have dispersed from there to other parts of the state. Salinity and disturbance mediate direct and indirect plant–plant interactions in an assembled marsh community. Normally grows with Distichlis spicata. The hybrids also produce much larger numbers of fertile seeds than the native Spartina, and are producing a hybrid population that, left unchecked, can increase not only in population size but also in its rate of population growth. Spartina alterniflora monocultures dominate low marsh habitats while the seaward border of high marsh habitats is generally dominated by Spartina patens. Tidal flooding diminishes the effects of livestock grazing on soil micro-food webs in a coastal saltmarsh. var. The hybrids produce enormous amounts of pollen, which swamp the stigmas of the native S. foliosa flowers to produce even larger numbers of hybrid offspring, leaving the affected native Spartina little chance to produce unhybridized offspring. S. alterniflora thrives in anoxic low marsh habitats due to its ability to oxygenate its roots and rhizosphere. Callaway, J.C., and M. N. Josselyn. Duncan, Wilbur H.; Duncan, Marion B. Soil-geomorphology relationships and landscape evolution in a southwestern Atlantic tidal salt marsh in Patagonia, Argentina. Response and resilience of Spartina alterniflora to sudden dieback. This suggests that the success of S. alterniflora in anoxic habitats is size dependent and may be driven by group benefits of rhizosphere oxidation. Spartina alterniflora (Spartina) is the only halophyte in the salt marsh.However, the molecular basis of its high salt tolerance remains elusive. Plant distribution along an elevational gradient in a macrotidal salt marsh on the west coast of Korea. One example of an invasive Spartina alterniflora hybrid is that of Spartina anglica.

Grows between the low- and high-tide marks in salt and brackish marshes, forming dense colonies that usually parallel the shoreline. King, C. Ferris, D. R. Ayres, and D. R. Strong. As of 2016, the infestation had been reduced to less than 3 solid hectares (7 acres). Rhizosphere oxidation by S. alterniflora, however, is not evident in seedlings and small colonizing patches and both seedlings and small colonizing patches of S. alterniflora are stunted in anoxic low marsh substrates. • CT, MA, ME, NH, RI.
