Abstract
Trait-mediated interactions across trophic levels drive trophic cascades in macroecological systems, yet their relevance in microbially dominated soil ecosystems remains underexplored. We combined a regional field survey with controlled experiments using a defined 122-strain synthetic bacterial community and bacterivorous nematodes to test whether faunal predation reorganizes root-associated microbiomes to suppress soilborne disease. Field observations showed that sites with stronger nematode-Pseudomonadota associations had lower bacterial wilt incidence. In controlled experiments, nematode predation selectively enriched Pseudomonadota in the rhizosphere and reduced Ralstonia solanacearum populations and…
