Abstract

Populations of living Foraminifera were studied from six areas of marine marsh in Galveston Bay. The general marsh foraminiferal assemblage is an Ammotium salsum-Miliammina fusca one, with common Ammonia beccarii, Arenoparrella mexicana and Trochammina inflata, and also containing Ammoastuta inepta, Elphidium spp., Tiphotrocha comprimata, and Trochammina macrescens in somewhat smaller frequencies. The following marsh environments have distinctive assemblages of Foraminifera: (1) channel or bay bordering a marsh, (2) fringing Spartina Zone, (3) Salicornia berm, (4) inner Spartina zone, (5) inner Salicornia zone, (6) lagoon barrier marsh, (7) more saline marsh, and (8) less saline marsh. Living populations are very small to very large, living-total population rates are large and deposition rates are high. Extreme range of environmental conditions limits the variety of marsh Foraminifera. Knowledge of the environment is inadequate to explain distributions within the marsh.
