Biological Flora Of Coastal Wetlands: Sporobolus Cynosuroides (L.) P.M. Peterson & Saarela, Richard Stalter, Robert I. Lonard
Biology Faculty Publications and Presentations
Sporobolus cynosuroides (L.) P.M. Peterson & Saarela¼Spartina cynosuroides (L.) Roth is a temperate zone rhizomatous grass that often is a dominant species in coastal brackish marshes on the Gulf coast and Atlantic coasts of the United States where salinity ranges from 0 to 10 psu. Sporobolus cynosuroides (L.) P.M. Peterson & Saarela ¼ Spartina cynosuroides (L.) Roth is usually absent where salinity values are .12 psu. Sporobolus cynosuroides occurs in coastal habitats characterized by infrequent tidal flooding and moderate nutrient levels. Also known as big cordgrass, it may account for net productivity in high marshes that rivals productivity of Sporobolus …
Biological Flora Of The Tropical And Subtropical Intertidal Zone: Literature Review For Rhizophora Mangle L., Hudson R. Deyoe, Robert I. Lonard, Frank W. Judd, Richard Stalter, Ilka Feller
Biological Flora Of The Tropical And Subtropical Intertidal Zone: Literature Review For Rhizophora Mangle L., Hudson R. Deyoe, Robert I. Lonard, Frank W. Judd, Richard Stalter, Ilka Feller
Biology Faculty Publications and Presentations
Rhizophora mangle L. is a tropical and subtropical mangrove species that occurs as a dominant tree species in the intertidal zone of low-energy shorelines. Rhizophora mangle plays an important role in coastal zones as habitat for a wide range of organisms of intertidal food webs, as a natural barrier to coastal erosion, and as carbon sequestration. A review of mangrove literature has been performed, but a review specifically on red mangroves has not. The approach was to cover a broad range of topics with a focus on topics that have seen significant work since the 1970s. This review includes a …
The Biological Flora Of Coastal Dunes And Wetlands: Avicennia Germinans (L.) L., Robert I. Lonard, Frank W. Judd, Kenneth R. Summy, Hudson R. Deyoe, Richard Stalter
The Biological Flora Of Coastal Dunes And Wetlands: Avicennia Germinans (L.) L., Robert I. Lonard, Frank W. Judd, Kenneth R. Summy, Hudson R. Deyoe, Richard Stalter
Biology Faculty Publications and Presentations
Avicennia germinans (L.) L. is a pantropical, subtropical, and occasionally warm-temperate mangrove species that occurs on shorelines that have a broad horizontal tidal range. Also known as black mangrove, stands typically develop under anoxic, water-logged conditions in substrates of silt or clay. Black mangrove can tolerate salinity values ranging from 0 to 90 parts per thousand. Salt is excreted from salt glands on both leaf epidermal surfaces, and aerosol salt spray and salt crystals are frequently observed on the upper leaf epidermis. Avicennia germinans is viviparous. The embryos have no dormancy requirements, and there is no seed bank. This mangrove …

Biological Flora Of Coastal Dunes And Wetlands: Borrichia Frutescens (L.) Dc., Robert I. Lonard, Frank W. Judd, Richard Stalter
Biology Faculty Publications and Presentations
Borrichia frutescens (L.) DC. is a New World warm-temperate, subtropical, and tropical zone, perennial subshrub that is an important species in hypersaline coastal sites. Also known as sea ox-eye, it tolerates salinities ranging from less than 20 ppt to 130 ppt. It occurs in substrates low in organic matter and deficient in nitrogen, phosphorus, and potassium. Nearly all reproduction is vegetative from an extensive rhizome system. Populations of this species recover quickly after coverage by wrack. Stands of B. frutescens often dominate the landward border of salt marshes.

Beach morning glory, Ipomoea imperati (Vahl) Griseb. = I. stolonifera (Cirillo) Gmelin is a pantropical, prostrate vine that is an important pioneer species in the backshore of coastal beaches of six continents and many islands. The landward distribution of beach morning glory is influenced by dispersal and competition, and its seaward distribution is determined by the physical environment acting through movement of seeds away from the water and high seedling mortality in the backshore. It is occasionally found in disturbed sites on barrier islands well inland from the shore. Beach morning glory tolerates low levels of soil nutrients, sand scouring, …

The Biological Flora Of Coastal Dunes And Wetlands. Sesuvium Portulacastrum (L.) L., Robert I. Lonard, Frank W. Judd
Biology Faculty Publications and Presentations
Sesuvium portulacastrum (L.) L. (sea purslane, cenicilla) is a pantropical, perennial, trailing herb (Aizoaceae) with pink-purple or occasionally white flowers that grows on coastal beaches of five continents and many islands. Herein we present a review of the biology of S. portulacastrum. It is an important pioneer species on sandy beaches in the subtropics and tropics, where its stoloniferous, mat-forming growth habit promotes embryonic dune formation in belts parallel to the shoreline. Colonies act as barriers to intercept and hold water and wind transported sand. Sesuvium portulacastrum's success as a colonizing species is related, in large part, to its …
