Dataset AbstractWetland food webs have often been characterized as detrital-based ‘brown’ energy pyramids, whereas the relative role of autotrophic (‘green’) vs. microbial (‘brown’) energy sources falls along a continuum set by physical drivers, as well as autochthonous and allochthonous inputs (Moore et al. 2004; Evans-White & Halvorson 2017) that change with ecosystem development (Schmitz et al. 2006). In the Florida Coastal Everglades (FCE), metabolic imbalances, including the collapse of calcareous periphyton mats, begin with a loss of foundation species primary production and legacy organic matter (Gaiser et al. 2006a). This process likely enhances heterotrophic microbial productivity (Schulte 2016) and the supply of detrital energy to consumers by changing bioavailable and recalcitrant carbon supplies (Baggett et al. 2013). A shift from complex periphyton communities to transient planktonic communities under elevated P exposure reduces habitat structure and animal refuges but increases ‘green’ energy supplies and edibility (Trexler et al. 2015; Naja et al. 2017; Fig. 15). Multiple sites (n=9) within the FCE were selected to document changes in coastal food webs as a result of eutrophication and increasing hydrologic variability. The project began in 2019 and is currently ongoing.

MethodsMethod Step
Description
Producers, consumers and organic matter were collected from each site using a variety of methods. Collection, preparation, and stable isotope methodology outlined below: Suspended Particulate Organic Matter (SPOM): Replicates (n) = 2 Collected via 50-m tows of 20μm plankton net. Contents sieved through a 250μm screen into amber bottles, immediately placed on ice, and returned to the lab. Once returned to the lab, contents were, dried at 55°C and ground into a fine powder for stable isotope analysis.
Method Step
Description
Surface Sediment Organic Matter (SSOM): Replicates (n) = 5 Collected from top 2cm of sediment via falcon tubes and immediately placed on ice. Once returned to the lab, contents of falcon tube were sieved through a 500μm to remove detritus and other large particulates. Remaining materials were dried at 55°C and ground into a fine powder for stable isotope analysis.
Method Step
Description
Benthic Algae: Replicates (n) = 5 Rocks, pebbles, and shells not containing macroalgae were collected, immediately placed on ice, and returned to the lab. Once returned to the lab, these materials were brushed with a toothbrush into artificial seawater, sieved through a 250μm screen. Contents were then dried at 55°C and ground into a fine powder for stable isotope analysis.
Method Step
Description
Epiphytes/Periphyton: Replicates (n) = 5 Collected via falcon tubes from macrophytes, mangrove roots, and existing infrastructure (i.e., receiver bases and buoys), immediately placed on ice, and returned to the lab. Once returned to the lab, materials were dried at 55°C and ground into a fine powder for stable isotope analysis.
Method Step
Description
Abundant Flora: Replicates (n) = 5 Collected by hand, immediately placed on ice, and returned to the lab. Once returned to the lab, materials were dried at 55°C and ground into a fine powder for stable isotope analysis.
Method Step
Description
Abundant Invertebrates: Replicates (n) = 5 Collected via traps, throw trap sampler, seines, or by hand. All samples were immediately placed on ice and returned to the lab. Once returned to the lab, materials were dried at 55°C and ground into a fine powder for stable isotope analysis.
Method Step
Description
Abundant Fishes: Replicates (n) = 5 Collected via electrofishing, throw trap sampler, traps, hook & line, or by seine. All samples were immediately placed on ice and returned to the lab. Once returned to the lab, materials were dried at 55°C and ground into a fine powder for stable isotope analysis. *all samples were collected within ~300m of each site point during dry and wet seasons *all samples containing carbonates were acidified with 10%hydrochloric acid and rinsed with deionized water before stable isotope analysis.
Method Step
Description
Stable Isotope Analysis: Dried samples of producer, consumer, and organic matter were weighed, wrapped, and shipped to Washington State University’s Isotope Core Laboratory for analysis: Delta Carbon 13, Delta Nitrogen 15, Delta Sulfur 34, Percent Carbon, Percent Nitrogen, and Percent Sulfur were estimated via mass spectrometry (DELTA Q™ Isotope Ratio Mass Spectrometer, Thermo-Scientific™).
