Carbon and nitrogen isotopic values from three omnivorous turtles, vegetation, and potential prey resources in the Santa Fe River, Florida sampled 2019-2020 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. Categories: Data; Tags: Ecology, Florida, Lower Suwannee, USGS Science Data Catalog (SDC), Wildlife Biology, All tags...

Red blood cells were collected from terrapins in 2011 (mature females), and whole blood samples were collected in 2015 and 2019 from mature males and females and immature females. Vegetation and invertebrates prey samples were collected within proximity of terrapin capture sites in 2015 and 2019.

Stable isotope ratios of carbon and nitrogen were evaluated from multiple tissues from terrapin populations to determine spatial or temporal variations in resource use within mangrove habitats in Southern Florida. We sampled Diamondback terrapin (Malaclemys terrapin) and potential resources within mainland and island habitats, and evaluated their δ13C and δ15N values. We fit linear regression models to determine the best predictors of isotopic values for both terrapins and their prey, and SIBER analysis to examine terrapin isotopic niche...
