Dynamics and resilience of earthworm fecal microbiomes under distinct feeding regimes

Popis výsledku v původním jazyce

Earthworms are ecosystem engineers, playing critical roles in soil food webs and ecosystems. Fresh feces from earthworms reflect a high diversity of earthworm's gut microbiome and play a crucial role in formation of soil aggregates. However, the effect of feeding regime switch on microbial community dynamics and resilience in earthworm feces remains elusive. To fill this knowledge gap, we incubated endogeic earthworms Aporrectodea rosea in laboratory microcosms, by feeding oak consistently, and by feeding oak or alder alternately. The earthworms were incubated for 10 weeks to explore dynamics and resilience of fecal bacterial and fungal communities. Both bacterial and fungal communities showed distinct temporal variations under different feeding regimes during 10 weeks incubation. Distinct feeding regimes were major factors determining community composition, taxa co-occurrence patterns, and the tradeoff of stochastic and deterministic processes in community assembly. Fungal communities showed a higher resilience than bacterial communities when diet was changed back, mainly reflected by changes in beta-diversity and alpha-diversity, and the abundance shifts of Ascomycota and Mucoromycota. In conclusion, our findings provide experimental evidences that the fecal microbial communities in the earthworms are determined by complex interplay of the actual food sources and their previous feeding history.
