The four species sampled were Florida bass (Micropterus floridanus), bowfin (Amia calva), common snook (Centropomus undecimalis), and red drum (Sciaenops ocellatus). We sampled diets via pulsed gastric lavage, a relatively non-lethal and effective sampling technique used to measure trophic interactions. We quantified trophic transfer of marsh biomass to the estuary when a focal piscivore consumed a prey species that was likely a migrant from adjacent marshes. A more detailed description of these methods can be found in citation #28. In the presented data, we combined estimates of relative abundance of piscivores from standardized electrofishing techniques (# of piscivores/ 100 meters of sampled shoreline) with biomass of marsh species consumed in the estuary to calculate the biomass (g) transferred to the estuary per 100 meters of shoreline. These values serve as our index of how much biomass is being exported off of the marsh to the estuary through consumer mediated habitat linkages. An important key finding from this work is that disturbance, in particular drought, can sever this biomass linkage, and conserve biomass export off of karstic wetlands to estuaries through of marsh secondary consumer trophic pathways.

Boat electrofishing is an effective sampling technique in freshwater habitats, including the Everglades, and has been used successfully to sample upper estuarine fish communities (Rehage and Loftus 2007). We conducted three replicate electrofishing bouts (timed sampling transects) at fixed locations in each site, each 200 m apart. For each bout, we ran the boat at idle speed at a randomly-selected creek shoreline and applied power for 5 min of time, during which two netters captured all immobilized fishes. We standardize power output to 1500 Watts, given temperature and conductance conditions measured at the beginning of each bout.

We hypothesize that disturbance, not only has an immediate effect on these wetland trophic biomass linkages but also leaves a multiple year legacy on these linkages. We also hypothesize the directionality of effects (either positive or negative effects) on these marsh-estuary linkages from disturbance will vary depending on disturbance.
