Protozoa-driven micro-food webs shaping carbon and nitrogen cycling in reservoir ecosystems.

ABSTRACT: Protozoa-driven micro-food webs are pivotal regulators of microbial community structure and carbon-nitrogen cycling. By mediating trophic cascades that regulate bacterial and algal populations, protozoa influence nutrient remineralization and energy flow. Their regulation is crucial for stabilizing biogeochemical processes and preventing harmful algal blooms. However, little is known about the detailed relationship between the traits of micro-food webs and carbon/nitrogen cycling processes. Using metagenomic data, we investigated the complexity and stability of micro-food webs in three distinct zones of the Fenhe Reservoir-the inflow river zone, shallow wetland, and deep-water zone-to assess their impacts on carbon and nitrogen cycling. Our findings revealed distinct spatial patterns in mi
