Alligator pond food-web sampling in Shark River Slough and Taylor Slough, Everglades National Park, Florida, USA, 2018–2019

These datasets were used to investigate if American Alligators engineer differences in nutrient availability and changes to community structure by their creation of “alligator ponds” compared to the surrounding phosphorus (P)-limited oligotrophic marsh in the Everglades. We used a halo sampling design of three distinct habitats extending outward from ten active alligator ponds across a hydrological gradient. We performed nutrient analysis on basal food-web resources and quantitative community analyses, and stoichiometric analyses on plants and animals. These data underly the work in Strickland et al. (2023). An apex predator engineers wetland food-web heterogeneity through nutrient enrichment and habitat modification. Journal of Animal Ecology.
