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.

所有样本均采集于美国佛罗里达州北部圣达菲河（Santa Fe River）9公里长的河段范围内。2019年至2020年间，我们在3处不同采样点位对苏旺尼鳄龟（Macrochelys suwanniensis）、拟鳄龟（Chelydra serpentina）以及红耳龟指名亚种（Trachemys scripta scripta）的爪部组织进行了采样。我们在3处捕获点位中的2处龟类捕获点周边，采集了植被及潜在猎物的组织样本。所有采集的组织样本均用于稳定碳、氮同位素分析。
