Earthworms are keystone animals stimulating litter decomposition and nutrient cycling. However, earthworms comprise diverse species which live in different soil layers consume types of food. Microorganisms the gut likely to contribute significantly their ability digest organic matter, but this may vary among earthworm species. Here, we analyse effect food (litter) quality on microbiota changes during passage (from foregut hindgut) ecological groups. The endogeic (soil living) Aporrectodea caliginosa anecic (litter feeding) Lumbricus terrestris were fed with high- (rape leaves) low-quality (wheat straw) a microcosm experiment for 18 weeks. Irrespective species, alpha diversity bacterial fungal communities changed little passage, composition microbial generally resembling those more than litter. In addition, supported higher complex high-quality Further, L. less A. caliginosa, especially when Our findings indicate that predominantly shaped by they ingest, modulated feed group. Overall, results suggest primarily influence mixing spreading microorganisms from microhabitats through bioturbation rather digesting microorganisms.
