Supplementary Table 2.
Benthic, pelagic, and terrestrial resource reliance by zoobenthos in ten lakes of varying dissolved
organic carbon (DOC) concentration. We used a Bayesian stable isotope mixing model to
estimate zoobenthos reliance on each of those three resources in each lake, using C, N, and H
stable isotope ratio data. The data in the tables are the percentiles of the posterior probability
distributions for resource reliance. The last row in each table gives the percentiles of the prior
probability distribution. Zoobenthos included in this analysis were Trichoptera, Odonata and
Chironomidae collected from 1 m depth.
