Table 8 Predicted diet proportion of herbivorous cichlids in Lake Tanganyika from a Bayesian mixing model with δ13 C and δ15 N of each cichlid species as mixture data, those of periphyton within their territories and those of other benthic animals as source data

  1. Analyses were conducted by MixSIAR. δ13C and δ15N of Atyidae and Ephemeroptera are quite similar (as shown in Figure 1) and cannot be distinguished. The dominant dietary items are shown in bold.
