Carbon and nitrogen isotopic values from three omnivorous turtles, vegetation, and potential prey resources in the Santa Fe River, Florida sampled 2019-2020
June 16, 2023
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.

Dietary niche of three omnivorous turtle species in a northern Florida river: Insights from stable isotope analysis
Macrochelys suwanniensis (Suwannee Alligator Snapping Turtle) coexists with 2 other native large omnivorous turtle species (Chelydra serpentina [Snapping Turtle] and Trachemys scripta scripta [Yellow-bellied Slider]) in a 9-km section of the Santa Fe River in northern Florida. A major shift in dominant submersed aquatic vegetation prompted us to quantify trophic position and niche overlap among th
