Alternate Title

Bluegreen Algae of a Coastal Salt Panne and Surrounding Angiosperm Zones in a Louisiana Salt Marsh

Abstract

A one year study found nineteen species of bluegreen algae associated with a coastal salt panne and four surrounding angiosperm zones in a southwestern Louisiana salt marsh. A thin, unstratified, nearly homogenous algal mat composed primarily of Schizothrix calclcola, S. arenaria, and Nostoc spumigena was widely distributed over the marsh. The standing crop of bluegreens appeared to increase with angiosperm diversity, canopy density and height, and with declining salinity and light intensity.
