  • Dataset Abstract
    Periphyton data and environmental data collected between February 2005 to November 2014
    "The Comprehensive Everglades Restoration Plan (CERP) focuses on “getting the water right” in the south Florida ecosystem—getting the right amount of water of the right quality to the right places at the right time" (USACE & DoI, 2015. Central and Southern Florida Project Comprehensive Everglades Restoration Plan) in the Everglades ecosystems. To inform CERP, since February 2005 we have been investigating the spatio-temporal variations of distribution, biomass and diversity of algae (key aquatic primary producers) in periphyton mats in relation to hydrology, nutrients and pH, and other environmental conditions.

    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 et al. (accepted) Freshwater Biology].

    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 in 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 thoroughly checked by Luca Marazzi and Franco Tobias.
