Oxygen Deficiency in Spartina alterniflora Roots: Metabolic Adaptation to Anoxia
TL;DR: The aerenchyma (air-space) tissue in the wetland macrophyte Spartina alterniflora conveys sufficient oxygen to roots for predominately aerobic respiration in moderately, but not highly, reduced substrates.

Abstract: The aerenchyma (air-space) tissue in the wetland macrophyte Spartina alterniflora conveys sufficient oxygen to roots for predominately aerobic respiration in moderately, but not highly, reduced substrates. Continuously flooded plants survive by respiring anaerobically, although growth is decreased. Two metabolic adaptations to flooding are displayed in this species, depending on the degree of soil reduction.

Determinants of Pattern in a New England Salt Marsh Plant Community
TL;DR: Physical disturbance and interspecific competition appear to be major determinants of the spatial pattern of marsh plant communities.

Zonation of Spartina Patens and Spartina Alterniflora in New England Salt Marsh
TL;DR: The results support the hypothesis that S. alterniflora is restricted to low marsh habitats by competitive displacement and suggest that the maintenance of intertidal zonation in rocky beach and marsh plant communities is very similar.

Interspecific Interactions among High Marsh Perennials in a New England Salt Marsh
TL;DR: The role of interspecific interactions among these marsh perennials in maintaining marsh plant zonation is examined and patch colonization by competitive subordinates appears to reduce substrate salinity by passively shading the substrate and facilitate the invasion of a superior competitor.

Fiddler Crab Regulation of Spartina alterniflora Production on a New England Salt Marsh
TL;DR: Experimental reduction of fiddler crab density for a single growing season decreased aboveground production and increased root mat density, while crab burrows were shown to increase soil drainage, soil oxidation- reduction potential, and the in situ decomposition of belowground plant debris.

Nitrogen vs. phosphorus limitation across an ecotonal gradient in a mangrove forest
TL;DR: In this paper, a factorial experiment with three nutrient treatment levels (control, N,P) and three zones along a tree-height gradient (fringe, transition, dwarf) on offshore islands in Belize was conducted.

The Chemistry of Submerged Soils
TL;DR: In this paper, the chemistry of submerged soils is discussed and the role of lake, estuarine, and ocean sediments as reservoirs of nutrients for aquatic plants and as sinks for terrestrial wastes.

Elemental analysis of deposits on the roots of spartina alterniflora loisel.
TL;DR: A study of streamside roots using scanning electron microscope and energy dispersive X-ray microanalysis demonstrated that the coatings are restricted to the outer cell wall of the epidermis and are composed primarily of iron as discussed by the authors.

Alcohol Dehydrogenase Activity in Relation to Flooding Tolerance in Roots
TL;DR: There was an increase in ethanol production under anaerobic conditions in those species whose growth was reduced by flooding, and it is suggested that species in which activation occurs are excluded from wet areas because of the accumulation of toxic quantities of ethanol.

Inductive Flood Tolerance in Swamp Tupelo (Nyssa sylvatica var. biflora (Walt.) Sarg.)
TL;DR: The combined adaptations of accelerated anaerobic respiration in the absence of 0 2, oxidation of the rhizosphere, and CO2 tolerance of new roots appear to be sufficient conditions to account for flood tolerance in this species.
