A Bayesian stable isotope mixing model for coping with multiple isotopes, multiple trophic steps and small sample sizes

A Bayesian stable isotope mixing model for coping with multiple isotopes, multiple trophic steps and small sample sizes

Abstract We introduce a Bayesian stable isotope mixing model for estimating the relative contributions of different dietary components to the tissues of consumers within food webs. The model is implemented with the probabilistic programming language Stan. The model incorporates isotopes of multiple...
