Yet compound-specific trophic discrimination factors have not been estimated for a broad range of habitats, taxa, and diets. We conducted a controlled-feeding experiment to characterize the variation in compound-specific (TDF<jats:sub>AA</jats:sub>) and bulk (TDF<jats:sub>Bulk</jats:sub>) trophic discrimination factors of four freshwater fish species fed on three distinct diets. We also compared TDF<jats:sub>AA</jats:sub> of fish muscle and scale to evaluate the viability of scales for making food web inferences. Mean ± 1 SD TDF<jats:sub>Bulk</jats:sub> was 2.2‰ ± 0.9‰, and there were significant effects of species and diet trophic position on TDF<jats:sub>Bulk</jats:sub>. Mean ± 1 SD TDF<jats:sub>AA</jats:sub> was 6.9‰ ± 0.8‰. Although there was no effect of species on TDF<jats:sub>AA</jats:sub>, there were significant differences in TDF<jats:sub>AA</jats:sub> across the three diets. TDF<jats:sub>AA</jats:sub> from fish scales were not significantly different from those of muscle. Our study illustrates the advantages of estimating trophic position using compound-specific stable isotopes and the need for continued investigation of factors resulting in variation in TDF values. </jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320096333956","@type":"Researcher","foaf:name":[{"@value":"Chelsey M.
