Abstract

Protists are important microbial consumers and phototrophs in terrestrial ecosystems and play pivotal roles in nutrient cycling and plant performance. The predation pressure of protists significantly impacts the composition and function of microorganisms, and in turn bacteria and fungi, as the key food sources of protists, may shape the distribution of protists. However, how trophic interactions (i.e. biotic factors), together with environmental factors, regulate the community structure and functional traits of protists in natural soil ecosystems – with no or limited anthropogenic impacts - remains largely unknown. Here, we assessed the influences of biotic (vegetation types, bacteria, fungi..
