AB This study investigated the ecosystem interactions and algal processes in the Florida Everglades, where phosphorus pollution threatens ecological health. Two different studies, 1995 and 1996, were conducted in which algae were sampled along a phosphorus gradient in Water Conservation Area-2A to determine the relationship among phosphorus enrichment and sedimentary algae, floating Cyanoprokaryota mats, and Eleocharis periphyton. The first objective was to explain the effect of phosphorus on living sedimentary algae by using CA, CCA, and Pearson’s correlations. Relative abundance of diatoms declined while Cyanoprokaryota increased with higher P concentrations. Sedimentary phosphorus explained more variation in taxonomic composition of sedimentary algal assemblages than water column or floating mat P. The Cyanoprokaryota with heterocysts, 5 algal genera and 7 algal species were positively correlated to phosphorus concentrations, while 3 genera and 7 species were negatively correlated.
