Assessment of stream macroinvertebrate communities with eDNA is not congruent with tissue-based metabarcoding.

abstract：:Diet strongly influences the intestinal microbial communities through species sorting. Alternatively, these communicates may differ because of chance variation in local microbial exposures or species losses among allopatric host populations (i.e. ecological drift). We investigated how these forces shape enteric commun...
