Seasonal Transformations of Manganese in a Palustrine Emergent Wetland

Soil Science Society of America Journal, 2002
Naturally occurring wetlands need to be investigated to assess their role in contaminant sequestration. Accordingly, aqueous‐ and solid‐phase analyses were conducted to monitor Mn response to changing physicochemical conditions within a Palustrine Emergent Wetland. A rhodochrosite‐like phase (MnCO 3

Growth Rates of American Alligators in Estuarine and Palustrine Wetlands in Louisiana

Estuaries and Coasts, 1991
A comparative study of American alligator (Alligator mississippiensis) growth rates was made in estuarine and palustrine wetlands in southwestern Louisiana. In the estuarine wetlands, where characteristic salinity levels were ≤5%, alligators grew faster and therefore reached sexual maturity earlier than did those in palustrine wetlands, which are ...

Studies toward the Synthesis of (+)-Palustrine:  The First Asymmetric Synthesis of (−)-Methyl Palustramate

The Journal of Organic Chemistry, 1998
The stereoselective synthesis of (-)-methyl palustramate, a possible intermediate for the synthesis of (+)-palustrine, is described. The key step of the synthesis is a conformationally restricted Claisen rearrangement to afford the highly functionalized 1-benzylpipecolic ester 10.

Paleocene palustrine and ephemeral alluvial facies in southern Sardinia (Italy)

Italian Journal of Geosciences, 2015
Paleocene ephemeral alluvial and palustrine deposits have been recognized in several small outcrops in southern Sardinia. Three sedimentary units have been distinguished: the basal one, mainly terrigenous, made up of alluvial pedogenized deposits, the intermediate one, entirely carbonate, made up of pedogenized fresh water deposits, and the third one ...

Flood Tolerance Indices for Palustrine Forest Species

1988
Since a definite relationship exists between plant species distribution and timing, frequency and duration of inundation/soil saturation (Bedinger, 1971; Hook and Scholtens, 1978; Whitlow and Harris, 1979; Huffman, 1980; Larson, Bedinger, Bryan, Brown, Huffman, Miller, Rhodes and Touchet, 1981), it should be possible numerically to express the optimum ...

Phosphate Removal Capacity of Palustrine Forested Wetlands and Adjacent Uplands in Virginia

Soil Science Society of America Journal, 1999
We examined the ability of soils in six nontidal palustrine forested wetlands (PFOs) in Virginia's Piedmont (PD) and Coastal Plain (CP) to remove dissolved inorganic P from solution, and we compared the P sorption capacities of wetlands with those of streambanks (within wetlands) and ...
