Data for Stable isotopes and diet metabarcoding reveal trophic overlap between native and invasive Banded Killifish (Fundulus diaphanus) subspecies

Data associated with the manuscript "Stable isotopes and diet metabarcoding reveal trophic overlap between native and invasive Banded Killifish (Fundulus diaphanus) subspecies." by Jordan H. Hartman, Mark A. Davis, Nicholas J. Iacaruso, Jeremy S. Tiemann, Eric R. Larson. For this project, we sampled six locations in Michigan and Illinois for Eastern and Western Banded Killifish and primary consumers. Using stable isotope analysis we found that Eastern Banded Killifish had higher variance in littoral dependence and trophic position than Western Banded Killifish, but both stable isotope and gut content metabarcoding analyses revealed an overlap in the diet composition and trophic position between the subspecies. This dataset provides the sampling locations, accession numbers for gut content metabarcoding data from the National Center for Biotechnology Information Sequence Read Archive, the assignment of each family used in the gut content metabarcoding analysis as littoral, pelagic, terrestrial, or parasite. and the raw stable isotope data from University of California Davis.

本数据集与Jordan H. Hartman、Mark A. Davis、Nicholas J. Iacaruso、Jeremy S. Tiemann及Eric R. Larson合著的论文《稳定同位素与饮食宏条形码技术揭示本土与入侵带状鳉鱼（Banded Killifish, Fundulus diaphanus）亚种间的营养级重叠》相关。在本项目中，我们于密歇根州和伊利诺伊州的6个地点采集了东部及西部带状鳉鱼样本，以及初级消费者（primary consumers）样本。通过稳定同位素分析（stable isotope analysis），我们发现东部带状鳉鱼在沿岸依赖性（littoral dependence）和营养级位置（trophic position）上的变异程度高于西部带状鳉鱼；然而，稳定同位素分析与肠道内容物宏条形码分析（gut content metabarcoding analysis）均显示，这两个亚种在饮食组成与营养级位置上存在重叠。本数据集包含采样地点信息、美国国家生物技术信息中心序列读取档案库（National Center for Biotechnology Information Sequence Read Archive）中肠道内容物宏条形码数据的登录号、肠道内容物宏条形码分析中涉及的各分类群（family）的生境类型（沿岸、远洋、陆生或寄生）分配，以及来自加州大学戴维斯分校（University of California Davis）的稳定同位素原始数据。
