  • Dataset Abstract
    This data package contains peripihyton and environmental data collected annually during the wet season between 2005 and 2014 from sites distributed throughout the greater Everglades ecosystem. This project is part of the Comprehensive Everglades Restoration Program's Monitoring and Assessment Plan intended to document baseline variability in periphyton attributes for assessing the effectiveness of restoration projects. A total of 200 primary sampling units (PSU) of 800 m x 800 m are nested in 32 landscape units and each year, random coordinates are 'drawn' within each PSU and one sampleable draw is visited in each. Sampled periphyton is processed for diatoms, slides are prepared, and 500 frustules are enumerated and identified to the lowest possible taxonomic resolution per slide. Taxon abundances are then relativized to the total count. These data accompany environmental, periphyton biomass, and soft algal abundance datasets.

    Study Extent Description
    Between February 2005 and November 2014, samples were taken in the Everglades ecosystem, from LOX to ENP (NE to SW; see Dataset geographic description).

    Bounding Coordinates
    Data were collected in Principal Sampling Units (800m x 800m) in the following regions (see list of sites at row 121). LKO: Lake Okeechobee; LOX: the Arthur R. Marshall Loxahatchee National Wildlife Refuge (Water Conservation Area 1); Pal Mar (PAL); Pennsuco (PEN), Lostman’s Creek (LMC), the ‘Oligohaline’ area (OLG), Southern Marl Prairie (SMP), Shark River Slough (SRS) and Taylor Slough (TSL); Holey Land Wildlife Management Area (HOL), Water Conservation Areas (WCA) 2 and 3.

  • Methods
    Sampling Description
    Using generalized random-tessellation stratification, we chose a representative set of locations (800 m x 800 m principal sampling units, PSU), within which we sampled three sites in a habitat drawn from a pool of GPS coordinates. At sites where depth was < 1 m, and vegetation not too dense to hamper the formation of periphyton, and our movement in the field, we threw a 1 m3 enclosure, open both at the top and bottom, and collected samples of periphytic algae with a 120 mL plastic beaker from floating or benthic periphyton mats, depending on the depth. Where no mats were present, we took flocculent detritus from the benthos, as this also hosts algae; we then transported the samples back to the laboratory and froze them until analysis. We measured water depth (cm) with a metal ruler, and TP concentrations in the periphyton (μg g−1 dry weight) by means of colorimetry after dry combustion because water column concentrations are often below detection in this extremely oligotrophic wetland [Marazzi, L., E.E. Gaiser, V.J. Jones, F. Tobias, A.W. Mackay. 2017. Algal richness and life-history strategies are influenced by hydrology and phosphorus in two major subtropical wetlands. Freshwater Biology 62: 274-290. DOI: 10.1111/fwb.12866 ].

    Method Step

    Description
    A 120 mL sample of periphyton was collected at each site. Percent aerial cover of periphyton was estimated visually in the field. Ash-free dry mass per area (g/m2), Chlorophyll a (ug/m2), TP (ug/g), % organic content were measured in the laboratory, and water temperature, water depth, conductivity, and pH were measured in a sample brought back from the field. Hydroperiod data come from the Everglades Depth Estimation Network (EDEN; http://sofia.usgs.gov/eden/). Information on mat type, soil type, and plants to which periphytic algae were attached was also gathered from field observations.


    Quality Control
    Data were entered into excel files and then cross-checked and validated by two individuals before migrating into a database.
