Summary
All samples were collected within a 9km stretch of the Santa Fe River in northern Florida, USA. In 2019 and 2020 we sampled claw tissue from Macrochelys suwanniensis, Chelydra serpentina, and Trachemys scripta scripta, from three different sampling locations. We collected Vegetation and potential prey tissue samples within close proximity of turtle captures from two of the three capture locations. All tissues were used for stable carbon and nitrogen isotope analysis.

We collected these data to investigate the trophic interactions among three omnivorous species by examining their isotopic niche. Basal resources from the upper and lower Santa Fe River sampling locations were collected to establish isotopic baselines of the food web at each location. In addition to identifying current critical habitat and resources, this data will provide a baseline for comparison with future samples to facilitate interpretation of demographic changes that may be detected during long-term study of this population.
