Hydrogen stable isotopes (dH) are used for quantifying resources supporting food webs. However, application of dH in mixing models requires; (1) correction for environmental water (x) in consumer tissues, (2) consideration of differential fractionation among biochemical constituents, and (3) consideration of differential H-exchange among samples and standards. We present data and sensitivity analyses addressing each of these issues and provide recommendations for future isotope food web studies… CONTINUE READING
