  • Dataset Abstract
    Periphyton biomass was measured quarterly at three replicate locations (1, 2, and 3) at FCE LTER marsh sites (SRS 1-3; TS/Ph 1-3). A 1-m2 plot was placed in the marsh and percent cover of periphyton was visually estimated, including cover on the water surface (floating), plant stems (epiphytic), and on the bottom (benthic). Periphyton was then harvested from the quadrats into a 2000 ml perforated graduated cylinder and the volume measured. A 120-ml subsample was removed and taken back to the laboratory for analysis. Data provided include percent cover by substrate, dry, ash, and ash-free dry mass per area, chlorophyll a per gram ash-free dry mass and per area, and the total phosphorus, nitrogen and carbon concentration on a dry weight basis. This is part of a continuous data collection to test the hypothesis that phosphorus and hydrology interact to influence periphyton abundance in Everglades marshes.

  • Methods
    Sampling Description
    Three random throws of the 1m square quadrat are made at each sampling site. Site, water and vegetation characteristics are recorded. Periphyton composition and volume are also recorded, and representative volume is brought back to the lab for processing and analysis

    Method Step

    Description
    Periphyton was characterized, measured and collected from three random throws in each LTER location. Periphyton was picked through for associated macrophytes and homogenized in distilled water. Subsamples were taken for measurements of dry mass, ash-free dry mass, chlorophyll a, species composition and total nutrient (C, N, P) content.
