Table 4. A comparison of the total and exclusive diet taxa identified in the foregut and hindgut digesta.

The taxa identified in each of the reactions pertain to diet taxa, therefore taxa identified as lobster (Astacidea), matching the DNA negative sample or identified as terrestrial were removed. The ‘diet hit count’ refers to the number of sequence reads matching a potential dietary reference sequences (identified as diet taxa) in the databases. The ‘exclusive taxa’ are those taxa found only in one category i.e., in the foregut digesta but not in the hindgut digesta.
