Tóm tắt

Soil food webs regulate microbial biomass and necromass production and are therefore critical for carbon sequestration. The mechanisms by which top predators regulate microbial necromass formation across multitrophic levels in the real-world soil food web remain nearly unknown. This study investigates how top-down forces-from omnivorous-predaceous nematodes to microbivorous nematodes and microbes-affect the formation of microbial necromass within tritrophic food webs under contrasting tillage regimes (tillage (till) vs. no-tillage (no-till)) on black soils (Mollisols), using a 1-year
